After spaceflight, astronauts often experience symptoms that affect their sensory systems, such as unsteadiness when walking or standing, blurred vision, and fatigue. These symptoms are called Bilateral vestibular disorder or BVP. Patients on Earth can also experience BVP, but they have different symptoms than astronauts who suffer from BVP. Scientists believe these differences occur in the part of the sensory system responsible for tracking head movement and body orientation in space. This includes the set of nerves in your ear. vestibular nerve.
Astronauts experience lower gravity than on Earth. Under these conditions, the organs in the inner ear that our brains use to sense head movement and spatial orientation don’t work properly. This makes it difficult for astronauts to determine their body’s actual position, movement, and altitude. After returning to Earth’s gravity, astronauts typically need to undergo rehabilitation to correct any resulting balance and coordination problems.
French researchers recently compared the symptoms of BVP experienced by astronauts during readjustment to Earth’s gravity with those of BVP patients on Earth. The team wanted to test strategies to help people on Earth adapt to BVP during rehabilitation, in hopes of establishing or improving rehabilitation strategies for astronauts returning from space.
The researchers recruited 28 astronauts, seven men and 11 women, with an average age of 48, all of whom lived on the spacecraft. international space station For 6 to 11 months. They also recruited 30 patients, including 13 men and 17 women with an average age of 61 years, all of whom had BVP but had never left Earth. They asked each participant to perform his five tests designed to examine mobility and reaction time.
To examine participants’ balance, we measured the time it took them to stand up from a sitting position and establish a stable posture.“Standing test”. They then measured how long it took them to walk around the cone. “Walk around test”. We then asked participants to: from heel to toe This is called the “tandem walk test” and is similar to walking a tightrope with your arms crossed in front of your chest. The researchers recorded each participant repeating this procedure twice and examined each recording to determine the correct number of steps taken during each trial.
The researchers also asked patients to track their progress for one minute while wearing the device. Virtual reality (VR) devices and earphones that mask external noise. The VR device instructed the patient to press the “run” button on the laptop mouse, wait 1 minute, and then press the “stop” button. They used this test, known as the “Duration Judgment Test,” to see how well each participant performed. I felt the passage of time. Finally, the participant who turned on the VR device was asked to respond as quickly as possible to a blue square that was displayed for 50 ms at random intervals.reaction time test. The researchers gave these tests to astronauts about three months before launch, once a month during spaceflight, two hours after returning to Earth, and 24 hours after returning to Earth. A test was conducted.
Researchers found that earthbound BVP patients walked around the cone more slowly than Astronauts did so during and after spaceflight. They also found that BVP patients took fewer correct tightrope steps than astronauts in the 24 hours after returning to Earth. However, the time it took for BVP patients on Earth to calm down during the sit-to-stand test fell between the day the astronauts landed and 24 hours later. Both BVP patients and astronauts who remained on Earth were unable to properly sense the passage of time and were slow to respond to blue squares.
The researchers concluded that problems with balance, sensing the passage of time, and reaction time experienced by astronauts after spaceflight are similar to those experienced by BVP patients on Earth. Therefore, they proposed that these problems, similar to those in earthbound patients, are caused by central nervous system dysfunction that affects the senses. To reduce these post-flight health problems, the researchers recommended that astronauts undergo training designed to improve their vision, hearing, and touch during orbit and after spaceflight.
The researchers cited two limitations of the study: the age difference between the astronauts and the Earth-bound group, and the fact that the BVP subjects on Earth received rehabilitation therapy, while the astronauts did not. I was warned that there was a point. They also were unable to test the astronauts post-flight to properly diagnose central nervous system conditions, so further research is needed to confirm whether the central nervous system is causing these symptoms. He pointed out that.
TThe ending of 1985’s Super Mario Bros., soundtracked by the iconic 8-bit NES beeps and blips, sees Mario finally find the princess who’s been in a different castle throughout the game. As her mustachioed hero jumps to her side, a speech bubble displays the digitized name of the damsel in distress: Princess Peach. She expressed her gratitude, her credits rolled, and we bid her farewell.
As anyone who saw Anna Taylor-Joy’s performance in last year’s Mario movie will know, the ruler of the Mushroom Kingdom has become rather less one-dimensional these days – the past 40 years have seen the rise of video games and feminism. You guessed it, considering how far we’ve come in the years. However, this is the second game in which she plays the leading role, after the 2005 DS game “Super Princess Peach.” On Showtime, Nintendo’s Pink She Princess literally takes the spotlight. When her trip to the theater goes awry, she must take to the stage to save theatrical art from…the evil vines.
It’s a strange but fun setting, allowing Peach to dive into a series of genre-themed side-scrolling levels. Each new setting provides a new starring role for our heroine, whether she’s traversing through grass, running across rooftops, riding a horse through railroad tracks, or lassoing bandits as the dagger-wielding ninja Peach. All of them are impressively handsome. Showtime’s colorful visuals are a joy, with well-animated bosses that fill the screen and attractive cakes. Still, it only takes a few minutes of play before you figure out the repetition.
From pressing buttons to stir cake mix as Patisserie Peach to the simple jumps and combat that define everything from swordplay to superhero fistfights, Showtime’s gameplay is thinner than Paper Mario. An unusual highlight here is his level of ice skating as Peach, wearing a leotard, races through a whimsical winter wonderland. There’s even a few smiles during the action-packed kung fu scenes, and the visuals lend an enjoyable level of kitsch to the rudimentary fisticuffs pastiche.
The problem is that while Mario’s House usually strikes a good balance between depth and accessibility, Showtime feels shallow. Whether it’s the demonic mermaid level or Detective Peach’s hilariously incomplete investigation, many of these potentially fun ideas feel like prototypes that prematurely escaped from Nintendo headquarters.
While last year’s Super Mario Wonder entertained all ages, Princess Peach: Showtime has little to offer those of us who have mastered the multiplication tables. Brilliantly scripted cinematic moments and visual variety provide color and flourish, but it’s a great shame that the inventive animation and narrative setting aren’t accompanied by the same level of gameplay innovation. is.
Despite a fun premise and high production values, Peach’s long-awaited turn to stardom feels disappointingly condescending, one-dimensional and forgettable, compared to the more capable heroines of the Super Mario Bros. movies. It is the exact opposite. As the Nintendo Switch enters her final years, this was the perfect moment to give the monarch of the Mushroom Kingdom the celebration she deserves. But whereas in The Forgotten Land Kirby received an Iliad-esque epic worthy of Mario, this one is more of a flimsy pop-up book.
I was going to start this article differently. But that was before my 10-year-old daughter intervened. In fact, I had already started writing when she got up and tried to trick me. She offered to bet me her ten pounds that I could write red with a regular pencil. Unfortunately for this budding entrepreneur, I turned down the bet. She was so confident that she suspected he was up to something. But I let her reveal the trick. She took her lead pencil in her hand and she wrote, “In red color.” Then she laughed like a hyena and went out to fool her mother.
Our bright little sparks have opinions on everything from video games to sports to books. She’s learning basic algebra and coding, but her Taylor Swift expertise far exceeds mine. But even with all this knowledge, she still has many years to go before she reaches adulthood. If she lives out her average lifespan, she will spend a quarter of her year as a minor.
It is truly strange that humans have long childhoods. No other primate takes this long to reach adulthood. During the evolution of our species, childhood has become significantly longer, along with more obvious physical changes. Traditionally, paleoanthropologists have paid little attention to children, but that is now changing. A series of interesting discoveries over the past few years are building a complete picture of human childhood. When did this seemingly unproductive life stage expand, why was it so long, and what did prehistoric children do? This discovery does more than just shed light on a dark corner…
Security officials have determined that Chinese state-backed hackers orchestrated two “malicious” digital campaigns targeting democratic institutions and politicians in the UK.
The UK holds China accountable for a cyberattack on its electoral commission, where the Chinese government allegedly accessed personal information of approximately 40 million voters.
The National Cyber Security Center, part of GCHQ, revealed that four British MPs critical of the Chinese government were targeted in a separate attack but were able to identify and prevent any compromise before it occurred.
The UK has imposed sanctions on two individuals and a front company associated with the Chinese state-backed cyber group APT31, believed to be behind the hack. “Beijing’s attempts to interfere in Britain’s democracy and politics have not succeeded,” noted Oliver Dowden.
Dowden emphasized that protecting democratic institutions is a top priority for the UK government and vowed to continue calling out and holding the Chinese government accountable for such activities.
The Foreign Office will summon the Chinese ambassador to answer for these actions, with Dowden stating that strong action will be taken if UK interests are threatened.
Since the cyberattacks in 2021 and 2022, the UK has bolstered its cyber defenses, established a Democracy Defense Task Force, and enacted the National Security Act of 2023 to empower security agencies to thwart hostile activities.
Members of Congress targeted by the cyberattacks are expected to be named by the government as victims of a Chinese state-sponsored cyber attack.
Former Conservative Party leader Iain Duncan Smith called for a new approach to the UK’s relationship with China, recognizing the modern Chinese Communist Party for what it is.
China denied the accusations, stating that the cyberattack claims are fabricated and defamatory, and that they do not condone cyberattacks.
Prime Minister David Cameron addressed the cyberattacks directly with Chinese Foreign Minister Wang Yi, condemning the targeting of UK democratic institutions.
The UK remains vigilant in protecting its values and democracy from threats, and emphasizes the importance of awareness of such threats for all countries.
In April, a total solar eclipse is expected to occur, promising great scientific success thanks to new spacecraft, telescopes, and cosmic coincidences.
The upcoming eclipse will feature the Moon very close to Earth, resulting in a prolonged period of darkness, and an anticipated increase in solar activity with possible dramatic plasma bursts. Additionally, densely populated areas from Mexico to America to Canada will witness this phenomenon.
During the eclipse, citizen scientists among the tens of millions of spectators will assist NASA and other research groups in studying our planet and stars. They will capture images of the sun’s corona as the moon blocks sunlight for up to 4 minutes and 28 seconds on April 8. The atmosphere will witness calm among birds and animals as darkness envelops midday. Other activities include measuring temperature drops, monitoring clouds, and using amateur radio to assess interruptions in communications.
Simultaneously, a rocket carrying scientific instruments will be launched into the ionosphere near the edge of the universe. This launch, from Wallops Island, Virginia, aims to study the electrically charged region of the atmosphere during the partial solar eclipse, obscuring 81% of the sun. NASA’s high-altitude jets will also be deployed with improved telescopes to observe the eclipse’s effects on the sun’s corona and surrounding dust.
Various scientific activities will take place along the eclipse path across different locations. More than 600 weather balloons will be launched for live-streamed atmospheric studies by university students, irrespective of cloudy skies. The eclipse will provide a rare opportunity to observe the sun’s corona, which is usually hidden by its glare, and offer valuable insights into the corona’s extreme temperatures.
The eclipse will traverse through several U.S. states, into Canada, and finally exit into the Atlantic Ocean. Scientists are looking forward to the event to gather valuable data and insights, especially with the heightened solar activity compared to the 2017 eclipse. With new spacecraft studying the sun and advanced scientific instruments in place, April’s solar eclipse promises a wealth of scientific discoveries.
This eclipse, passing through U.S. radar sites monitoring space weather, will offer a unique opportunity for scientific observation closer to home.
Some zoo animals contracted SARS-CoV-2 from humans

Animals such as rats are often considered carriers of the disease. But when it comes to the spread of disease, it turns out that other animals have more reason to fear us than we do.
Analysis of the viral genome found that when viruses move between humans and other animals, in 64% of cases they are transmitted from humans to other animals, rather than vice versa.
“We give more viruses to animals than they give us,” he says. Cedric Tan At University College London. For example, after the SARS-CoV-2 virus passed from bats to humans, likely through another species, humans passed the virus on to many other species.
Tan and his colleagues have been using a global database of sequenced viruses to study how viruses move between species. There are nearly 12 million sequences in the database, but many are incomplete or lack data on when and from which host species they were collected.
So the researchers narrowed down the 12 million to about 60,000 high-quality sequences with complete accompanying data. They then created a “family tree” of related viruses.
In total, approximately 13,000 virus lineages and 3,000 jumps between species were identified. Of the 599 jumps involving humans, most were from humans to other animals, not the other way around.
Tan says the team didn't expect this, but in retrospect it makes sense. “Our population size is huge. And our global footprint is basically everywhere.”
In other words, a virus that circulates among humans has many opportunities to spread to many other species around the world, whereas a virus that circulates among non-human species confined to a single region does not. That's far less.
Studies have found that SARS-CoV-2, MERS-CoV, and influenza viruses are the viruses most commonly transmitted by humans to other animals. This is consistent with other studies showing, for example, that SARS-CoV-2 spread from humans to pets, zoo animals, domestic animals such as mink, and wild animals such as white-tailed deer.
However, even when SARS-CoV-2, MERS-CoV, and influenza viruses were excluded from the analysis, the researchers found that 54 percent of infections were from humans to other animals.
The spread of viruses from humans to other species is a threat to many endangered animal species, Tan said. For example, outbreaks of human metapneumovirus and human respirovirus have killed several wild chimpanzees in Uganda.

Great tits appear to flap their wings to signal their mates to enter the nest, suggesting that birds may use a variety of gestures to communicate.
Signals such as hand waving are common aspects of communication between humans and other great apes. To learn more about such behavior of birds, Toshitaka Suzuki Professors at the University of Tokyo installed hundreds of nest boxes in forests where great tits live (minor pulse) For the past few years, near the town of Karuizawa.
To mimic the tree cavities that great tits normally inhabit, each box had a 7.5-centimeter-wide hole, just large enough to fit one bird at a time.
During the breeding season, the researchers observed 321 nest visits by eight pairs, with great tits often carrying food to feed the hatchlings.
When the couple arrives at the nest together, each tit perches on a nearby branch before entering the nest. About 40 percent of the time, the female turned her chest toward the male and flap her wings for a few seconds. Immediately the male entered the nest first, followed by the female.
However, when neither bird was flapping, which accounted for 44 percent of nest visits, the female usually entered the nest first. Only one male was observed flapping its wings repeatedly, and then the female moved in first. No flapping of wings was observed when each bird arrived separately.
“We can conclude that this wing flapping conveys ‘after you’ and encourages the male to enter the nest first,” Suzuki says. “This study is the first to demonstrate that birds can use wing movements to convey specific meanings.”
The findings suggest that great tits, and perhaps other bird species, communicate in a much more complex way than previously thought.
“There is a hypothesis that language evolved from communication through gestures,” Suzuki says. “Thus, these studies help us understand the evolution of complex communication, including our language.”
Gender gaps within science, technology, engineering, and mathematics (STEM) still persist despite significant advancements. Women continue to be underrepresented, with only 29.2% of STEM employees being women compared to nearly 50% in non-STEM occupations, as reported in the Global Gender Gap Report (2023).
However, the urgent need to address goes beyond just getting women into STEM. A recent study at UCL revealed that female she-STEM students are twice as likely to have experienced sex discrimination compared to non-STEM students.
With advancements in hackers and digital technologies, the demand for cybersecurity professionals is on the rise to combat digital threats. The global cybersecurity market is projected to reach $424.97 billion by 2030, highlighting the importance of closing the gender gap to address this deficit.
Throughout history, women in STEM fields have overcome barriers, but there is still a long way to go. Here are five remarkable women who have significantly contributed to STEM:

Cars have weight issues. The example of the Mini, designed to save fuel during rationing, highlights this trend. The size of cars is increasing, especially with the surge in popularity of SUVs.
Electric cars may look similar to traditional cars for now, but the key difference is the heavy battery they carry.
In our series debunking electric vehicle myths, we address common misconceptions about EVs, including range anxiety, carbon emissions, mining, and air pollution. In this final episode, we investigate whether electric cars will be too heavy for our roads and infrastructure.
Claim
As roads have evolved over time, concerns have arisen about whether electric cars will strain infrastructure like roads, bridges, and parking lots due to the weight of their batteries.
Matthew Lin, a columnist for the Daily Telegraph, recently questioned the readiness of charging infrastructure and the capacity of roads and bridges to handle heavier vehicles.
Conservative MP Greg Knight urged the UK government to test the structural integrity of multi-storey car parks and bridges against the added weight of electric vehicles.
The Asphalt Industry Alliance warned that small roads could suffer more potholes, while the Daily Mail suggested that multi-storey car parks might be at risk of collapse due to the weight of electric vehicles.
Science
Electric cars can be quite heavy. For example, General Motors’ Hummer weighs over four tons, with a significant portion of that weight attributed to its battery pack. On the other hand, the Tesla Model Y, a more affordable electric car, weighs 2 tons, still lighter than some traditional vehicles like the Range Rover or Ford F-150.

According to a transport and environment advocacy group, EVs are on average 300-400kg heavier than traditional vehicles. The weight of the battery increases by approximately 100kg for every 150km of range.
The increased weight of electric cars leads to more road wear and faster deterioration of roads. However, a study found that the wear is primarily caused by heavy vehicles like buses and trucks, rather than cars and motorcycles.

Regarding bridges, most in the UK can support vehicles weighing up to 7.5 tonnes, with a safety margin built into the design. There are no concerns about national highways, which are built to accommodate heavy goods vehicles.
There are limitations to the weight of electric vehicles, especially in older car parks. While newer facilities can accommodate heavier vehicles, older structures may require reinforcement to handle the increased weight.
Options for multi-storey car park owners include strengthening the building or reducing the number of cars on each floor, which can impact profits.
Regular inspections are essential for car park owners to ensure the structural integrity of their buildings amid the transition to heavier electric vehicles.
Governments could encourage smaller cars through policies such as taxes and parking fees. Photo: Christopher Thomond/The Guardian
It’s worth noting that advancements in battery technology may address the weight concerns of electric vehicles in the future. Continued progress in battery energy density could lead to lighter EVs in the long run.
Encouraging smaller cars through policy measures like taxes and fees can have additional benefits beyond reducing road wear, such as resource conservation, carbon emission reductions, and improved parking lot management.
While EVs are heavier than traditional vehicles, it’s unlikely that their weight will significantly impact road infrastructure. Concerns about weight should not overshadow the importance of transitioning to zero-emission vehicles.
In a new paper in the journal Nature Machine Intelligence, leading computer scientists from around the world review recent advances in machine learning that are converging towards creating collective machine-learned intelligence. They propose that this convergence of scientific and technological advances will lead to the emergence of new types of AI systems that are scalable, resilient, and sustainable.
Saltoggio other. In other words, we will see the emergence of collective AI, where many artificial intelligence units, each able to continuously acquire new knowledge and skills, form a network and share information with each other.
Loughborough University Dr. Andrea Sortoggio and colleagues recognize striking similarities between collective AI and many science fiction concepts.
One example they give is Borg – a cybernetic life form that appears in the Star Trek universe that operates and shares knowledge through a linked collective consciousness.
However, unlike many science fiction stories, the authors envision that collective AI will bring major positive breakthroughs across a variety of fields.
“Instantaneous knowledge sharing across a collective network of AI units that can continuously learn and adapt to new data enables rapid response to new situations, challenges, and threats,” said Dr. Sortogeo.
“For example, in a cybersecurity environment, when one AI unit identifies a threat, it can quickly share knowledge and prompt a collective response, which helps the human immune system protect the body from external intruders. It’s the same as protecting it.”
“It could also lead to the development of disaster response robots that can quickly adapt to the situation they are dispatched to, and personalized medical agents that combine cutting-edge medical knowledge with patient-specific information to improve health outcomes. Yes, the potential applications are vast and exciting.”
Researchers acknowledge that there are risks associated with collective AI (such as the rapid spread of potentially unethical or illegal knowledge), but that AI units have their own objectives and independence from the collective. The authors emphasize the important safety aspect of their vision: to maintain
“This will enable democracy for AI agents and greatly reduce the risk of AI domination by a few large systems,” said Dr. Sortoggio.
After analyzing recent advances in machine learning, the authors concluded that the future of AI lies in collective intelligence.
The study focuses global efforts on enabling lifelong learning (where AI agents can extend their knowledge throughout their operational life) and developing universal protocols and languages that allow AI systems to share knowledge with each other. It became clear that it was.
This differs from current large-scale AI models such as ChatGPT, which have limited lifelong learning and knowledge sharing capabilities.
Such models are unable to continue learning because they acquire most of their knowledge during energy-intensive training sessions.
“Recent research trends are extending AI models with the ability to continuously adapt once deployed, allowing their knowledge to be reused in other models, and effectively recycling knowledge to increase learning speed and energy.” It’s about optimizing demand,” said Dr. Sortogeo.
“We believe that the currently dominant large-scale, expensive, non-sharable, non-lifetime AI models will be replaced by sustainable, evolving, and shared collections of AI units in the future. I don’t believe I will survive.”
“Thanks to communication and sharing, human knowledge has increased step by step over thousands of years.”
“We believe that similar movements are likely to occur in future societies of AI units that achieve democratic and cooperative collectives.”

IIn 1956, a man TK “Ken” WhitakerAn Irish civil servant by training as an economist, he was appointed Permanent Secretary to the Treasury in Dublin at the relatively young age of 39. From his vantage point as the head of the national treasury, the outlook was bleak. The Republic of Ireland was in deep economic and social crisis. It had no natural resources, little industry, and was in deep depression. Inflation and unemployment were high. Ireland’s main export was young people, who fled by the thousands each year in search of work and a better life. The proud dream of Irish independence produced an impoverished nation of priests on the verge of collapse.
Mr. Whitaker quickly assembled a team of young officials to critically analyze the country’s economic failures and devise a series of policies to remedy them. As a result, a report titled “First Plan for Economic Expansion” was published in November 1958, and subsequently Sean Lemas He was elected Taoiseach (Prime Minister) in 1959 and became Ireland’s survival strategy.
At its heart were several important proposals. Ireland will have to embrace the idea of free trade. That would mean boosting competition and ending the protectionism that had been a feature of Irish economic policy under Lemas’s predecessor Airmon de Valera (whose economic philosophy was once described as “non-British”). But most importantly, the strategy requires that Ireland must welcome foreign capital in the future, which essentially means being nice to national companies, giving multinationals generous tax breaks, giving them help finding land to build on, and generally being responsive to their needs.
Whittaker’s strategy was bold, but it worked. (Of course, joining the European Economic Community in 1973 didn’t hurt either.) The republic moved from a state of deep socio-economic problems to an apparent paradigm of neoliberal prosperity. I have transformed. Foreign companies (mainly American companies) flooded in. German crane manufacturer Liebherr was an early entrant. In 1980, he was followed by Apple, and then came pharmaceutical companies. (Perhaps Viagra is manufactured in Ireland, once the holy land of Catholicism.) Then along came the big technology companies, many of which now have their European headquarters in Dublin.
If any of these behemoths had any doubts about coming to the Emerald Isle, two things would have reassured them. The first is Brexit. These companies had to join the EU. The second was how the republican government rushed to the rescue of one of its compatriots, Apple. When the European Commission concluded in 2016 that the company had been unfairly granted €13 billion in tax exemptions by Irish authorities, Apple not only successfully appealed this decision in 2020 but also had a similar ruling in 2020. was lowered. The republican government did it.. Think about it for a moment. A small country is refusing to accept her 13 billion euro payment. (Incidentally, the Commission has appealed this decision, and it appears Apple may still have to pay an additional €1.2 billion in interest. This money is currently held in an escrow fund with the Irish government.)
But the subconscious message to corporate bosses was: “If you run into trouble with the EU, we will support you.” This message may have reached Beijing as well. In any case, it is interesting to learn It comes just as the US and EU are considering cracking down on TikTok (whose owner ByteDance, coincidentally, is based in Dublin), and the Irish government is considering cracking down on popular e-commerce app Temu and other companies. It says that it welcomes Chinese-funded companies. Shein, and tech company Huawei.
I might regret this for the rest of my life, but for now, isn’t that all the treble? Only up to a certain point. On the one hand, the influx of foreign capital into Ireland was transformative. Tax revenue from resident high-tech companies is, on paper, making the country richer. The government is paying out of its ear. surplus
Meanwhile, Ireland faces some difficult problems. For example, corporate wealth has done to Dublin what Silicon Valley did to San Francisco, turning a once livable city into a highly unaffordable metropolis. There is a huge lack of affordable housing. A related homelessness crisis: around 12,000 people are in emergency accommodation, with an average monthly rent of €1,468. Add to that a creaky public health service (along with lavish and expensive private health services).
There is a paradox here. Mr. Whitaker’s strategy is to build enough affordable housing to build all the affordable housing the country needs, to fund a world-class public health system, and to build a mass transit system that frees up the nation’s capital. It brought in tax revenue and created a society that was clearly richer than his wildest dreams. Traffic congestion, electrification of everything, etc. Nevertheless, it is ruled by a coalition government that appears unable to look ahead to the next election. Perhaps it is true that we are getting the government we deserve.
Let’s prepare for an amazing event. A stunning lunar eclipse is set to occur on Monday, March 25, 2024, when the Earth aligns between the Sun and the Moon. This alignment causes the Earth’s shadow to fall on the Moon, resulting in a dimmer appearance.
This event coincides with the Festival of Colors, a traditional Hindu celebration marking the arrival of spring and new beginnings. For locations more than 6 hours behind GMT (west of Chicago), the eclipse will start on the night of March 24, 2024.

A penumbral lunar eclipse is scheduled for March 24th to 25th, 2024.
For viewers in the UK, the eclipse will take place a few hours before sunrise, with the moon setting as it reaches its maximum phase. In Bristol, the sunrise will be at 6am GMT on March 25th, placing the eclipse in the early morning sky just before the moon sets.
At 6:03 a.m. GMT, the eclipse will peak while the moon is still above the horizon. The true maximum at 7:12 a.m. won’t be visible as the moon will have set by then.
The moon will start to set at 6:11 a.m. GMT, but its proximity to the horizon and the eclipse phase may dim it before its descent, possibly making it almost invisible.
During a lunar eclipse, the moon will be above the horizon, providing better visibility for observers in the United States.
For Bristol, UK:
A penumbral solar eclipse begins: March 25th, 4:53 a.m. GMT (Moon visible on the horizon)
Maximum eclipse: March 25, 7:12 a.m. GMT (moon below the horizon)
Penumbral eclipse ends: March 25, 9:32 a.m. GMT (moon below the horizon)
For New York City, USA:
A penumbral solar eclipse begins: March 25th 12:53am ET (Moon visible above the horizon)
Maximum eclipse: March 25th, 3:12 a.m. ET (Moon visible on the horizon)
Penumbral eclipse ends: March 25th, 5:32am ET (moon visible on the horizon)
For San Francisco, USA:
A penumbral solar eclipse begins: March 24th, 9:53 PM PST* (Moon visible on the horizon)
Maximum eclipse: March 25th, 12:12am PST (Moon visible on the horizon)
Penumbral eclipse ends: March 25th, 2:32 a.m. PST (Moon visible on the horizon)
* In the United States, clocks changed to daylight saving time on March 10th. In the UK, clocks change to BST on March 31st.
Where can I see the lunar eclipse?
The lunar eclipse on March 25, 2024, will be visible across the United States, South America, Canada, the United Kingdom, Europe, Africa, Asia, Western Australia, and the Arctic and Antarctic regions.
For locations west of Chicago, Illinois, the eclipse will begin on March 24 and last until sunrise.
What exactly is a penumbral eclipse?
All objects cast two shadows when in front of a light source: the dark umbra and the bright penumbra. This remains true when the Earth is between the Sun and the Moon.
During a lunar eclipse, when the moon enters Earth’s penumbra, a partial shadow is formed. Penumbral eclipses are subtle and may be challenging to observe. On Earth, this translates to a gradual dimming of the Moon’s brightness.

During a total lunar eclipse, as the Moon enters Earth’s umbra, it takes on a reddish hue for a more dramatic effect. The intensity of the red color depends on the Moon’s position in Earth’s shadow, appearing blood red in the deepest shadow and pale red in partial shadow.
For future lunar residents, standing on the Moon during a lunar eclipse would reveal Earth blocking the Sun, a scenario where a solar eclipse is witnessed.
What causes a lunar eclipse?
A lunar eclipse occurs when the Earth moves in front of the Sun, casting its shadow on the Moon. Since the Moon reflects sunlight back to us, its visibility during a lunar eclipse is affected when this sunlight is obstructed.
There are different stages to a lunar eclipse: transition through Earth’s penumbra, entry into the dark umbra, return to the penumbra, and finally exit from the shadow completely.
During the upcoming lunar eclipse on March 24-25, 2024, the Moon will stay within the penumbra without entering the central umbra.
What constellation is the moon in?
The penumbral eclipse on March 24-25, 2024, will take place while the Moon is in Virgo, mirroring the placement of Spica, the brightest object in the constellation but slightly to the west.
Will the moon turn red?
Unfortunately, the lunar eclipse on March 24-25, 2024, will not be total, meaning the Moon will not turn red. At most, observant viewers may notice a slight darkening, far less dramatic than during a total lunar eclipse.
Under most circumstances, the lunar eclipse will go unnoticed: “Regrettably, this full moon will only pass through Earth’s darker outer shadow. The lunar eclipse will not be observable at all!” Dr. Darren Baskill, University of Sussex, remarks.
To visualize the distinction, Dr. Baskill suggests placing your hand between a bright light and a surface at night, observing the fainter penumbra surrounding the dark umbra of your hand.
Why do solar eclipses come in pairs?
Observant viewers will notice solar and lunar eclipses occurring successively. After the lunar eclipse on March 24-25, 2024, a solar eclipse will follow on April 8, 2024, promising an even more impressive celestial event.
This phenomenon arises from the alignment of the Sun, Earth, Moon, and their orbital planes.
The Moon’s orbit is slightly inclined compared to Earth’s orbit around the Sun, leading it to pass slightly above or below Earth’s orbital path. Despite this, specific points where the Moon’s orbit intersects Earth’s orbital path—termed “nodes”—exist.
During a solar eclipse season, recurring approximately every six months, alignments near these nodes permit both solar and lunar eclipses to occur. The full moon’s passage through Earth’s shadow creates a lunar eclipse, which is followed by a solar eclipse two weeks later, during the new moon phase, with the Sun, Earth, and Moon aligning perfectly.
When is the next lunar eclipse?
Following March 25, 2024, a partial lunar eclipse is slated for September 18, 2024, preceding a total lunar eclipse about a year later, on March 14, 2025.
Subsequent total lunar eclipses will occur in three consecutive instances, on September 7, 2025, and March 3, 2026.
Here is a list of upcoming lunar eclipses:
March 25, 2024: penumbra
September 18, 2024: Partial
March 14, 2025: total
September 7, 2025: total
March 3, 2026: total
August 28, 2026: Partial
February 20, 2027: penumbra
July 18, 2027: penumbra
August 17, 2027: penumbra
January 12, 2028: Partial
July 6, 2028: Partial
December 31, 2028: total
June 26, 2029: total
December 20, 2029: total
Tips for viewing the lunar eclipse
No special equipment is needed to observe a lunar eclipse, as it is entirely safe to view the moon even during the event. The moon reflects sunlight and lacks dangerous radiation. Therefore, it poses no threat to human eyes.
On a clear night, simply use your eyes to witness the eclipse. A reclining chair may enhance comfort during outdoor viewing. For UK spectators, the eclipse will transpire before dawn, with the moon low on the horizon, possibly visible from indoors if not obstructed by foliage.
To maximize visibility, avoiding areas with high light pollution remains crucial.

On the morning of March 28th, in a downtown Manhattan courtroom, Sam Bankman Freed, a tech genius turned con artist who remained unrepentant despite his trial and conviction, finally learned his fate.
Bankman Fried, who founded the virtual currency exchange FTX, was found guilty on November 2, 2023, of seven counts of wire fraud and money laundering conspiracy.
Fallen Bitcoin booster was found to have siphoned billions of dollars in customer funds to FTX’s sister hedge fund Alameda Research to stay solvent – His pockets were then stuffed with money from unlucky customers, precipitating the organization’s collapse.
“Sam Bankman Freed carried out one of the biggest financial frauds in American history, a multi-billion dollar scheme to make him the king of cryptocurrencies. However, the crypto industry was new and Sam Bankman Players like Bankman Fried may be new, but this type of corruption has been around for a long time,” Manhattan U.S. Attorney Damien Williams said after the conviction. “This case has always been about lies, deceit and theft, and we have no patience for that.”
Prosecutors then asked Judge Lewis Kaplan to impose a prison sentence of 40 to 50 years. They emphasized the “extremely serious nature of the harm to thousands of victims” and said:[prevent] Defendant shall not commit fraud again; [send] This sends a strong signal to those who attempt to engage in financial misconduct that the consequences will be severe. ”
In order to seek a heavier sentence, prosecutors submitted victim impact statements, revealing how individual and institutional investors were harmed by Bankman Freed’s actions.
“In 2022, at the age of 24, I lost all my life savings, which amounted to more than $20,000,” said one person who did not even try to invest in cryptocurrencies, but simply took advantage of the interest rate operated by FTX. I wrote that it was for a reason. – Bearing Savings Account.
Another victim, who said she had “invested a significant portion of her savings in FTX,” said she was staring at an uncertain future, adding: “Immense anxiety, stress and uncertainty about how I'm going to support myself and my family.” “It's causing sex,” he said.
The “disbelief and fear” the victim described upon learning of FTX’s financial crisis reflected the widespread shock at the exchange’s collapse. Bankman Fried has long been a rising star in the crypto world, attracting both investors and politicians with his trading platform.He argued that exchange was safer. – and less risky – than any other such platform. FTX rose to fame on the back of his advocacy, boosting Bankman Freed’s profile and lining his pockets.
FTX is a huge success: SBF became a millionaire before he was 30 years old
Before Bankman Fried turned 30, his fortune was in the billions. FTX and its biggest competitor, Binance, used to process most crypto transactions around the world.
All the while, with his uniform of T-shirts and shorts and lofty philosophical pronouncements, Mr. Bankman-Fried developed the persona befitting the next tech impresario. His parents, both law professors at Stanford University, studied utilitarianism (in effect, the concept that moral actions are those that achieve the greatest good for the greatest number of people), and it was through this context that he learned about commerce. declared that it would evaluate.
Bankman-Fried said he believes in effective altruism. This is a philanthropic endeavor beloved by big tech leaders who believe strategic giving to achieve the greatest number is a virtue. Some proponents of effective altruism promote an “earn to give mentality.” This means that accumulating extreme wealth is moral because it can be donated.
The former mogul's enthusiasm for contributing to society has also permeated politics. He has donated more than $40 million to the 2022 election.
Most of Mr. Bankman Fried’s donations went to the Democratic Party and related committees, but he also poured large sums of money into “dark” contributions to Republican candidates. According to CBS NewsBankman Fried wondered if she might have been the “second or third-largest” donor to the 2022 midterm elections.
While at the top, Bankman Freed chatted with celebrities including Bill Clinton and Tony Blair at the 2020 Cryptocurrency Conference in the Bahamas. He moved FTX to Caribbean countries because it employs a trading mechanism that is prohibited in the United States. new york times report.
Among Bankman Fried’s closest friends was Alameda Research CEO Caroline Ellison. Although their business relationship was complicated, Ellison and Bankman Freed continued an on-and-off romantic relationship over the years.
Like Bankman Freed, Ellison made lofty declarations. “Nothing makes us realize how stupid the normal unmedicated human experience is like regular amphetamine use,” she said in the paper. bomb tweet.
The FTX team's life in the Bahamas seemed to reflect the quirkiness that the tech industry loves. Bankman Freed, Ellison, and eight other members of his entourage lived together in the penthouse. reportedly Access to stimulants – Our in-house clinic will be happy to prescribe it for you.
Everything goes wrong: FTX goes bankrupt, SBF goes to court
Bankman Fried’s fortunes reversed in November 2022. That month, crypto industry publication CoinDesk report He reportedly held billions of dollars in FTT, FTX’s own cryptocurrency. There was a problem because the CEO was using FTT as collateral for a huge loan. When news broke about Binance’s FTT holdings, Binance CEO Changpeng Chao said that the company would dispose of its $500 million FTT holdings due to “recently revealed facts.” FTT plummeted, creating a virtual bank run among customers. FTX, like Alameda Research, sought bankruptcy protection.
It became clear to the outside world that there was an $8 billion hole in FTX’s budget. In December, the U.S. Attorney’s Office in Manhattan charged Bankman Freed with financial crimes for allegedly using customer and investor funds to make risky trades and assist Alameda Research.
At Bankman Freed’s trial in late 2023, the prosecution alleged that Bankman Freed was involved in a malicious fraud from 2019 until November 2022, when FTX went bankrupt. They claim Bankman Freed “misappropriated and misappropriated” FTX customers’ deposits and funneled “billions of stolen dollars” to bloat wallets and fund high-risk investments. did.
Prosecutors also said Bankman Freed shuffled funds to pay for his expensive lifestyle. They say the “exorbitant expenditures” unrelated to FTX covered Mr. Bankman Freed’s personal expenses, including more than $200 million in real estate in the Bahamas, speculative investments and repayments to Alameda’s lenders. said.
During Mr. Bankman-Fried’s month-long trial, his aides took the stand against him. Some of the most damning testimony came from his ex-girlfriend Ellison, who served as the prosecution’s star witness.
“Did you commit any crimes while working in Alameda?” Ellison was asked. She answered: “Yes, I did…” [Bankman-Fried] directed me to commit these crimes. ”
Despite numerous revelations about FTX’s questionable internal affairs, Bankman Fried made the shocking decision to testify in his own defense. “I made a lot of little mistakes and I made a lot of big mistakes,” Bankman Freed told jurors. “There was a serious oversight.”
Bankman Freed made management errors, including failing to establish a dedicated risk management team. But when attorney Mark Cohen asked if he had defrauded his clients or stolen their money, Bankman Fried responded, “No, I didn’t.”
When it came time for the prosecution to cross-examine Bankman-Fried, the lawyers questioned him on everything from his character. Mr Ellison told jurors that his appearance as limp and bedridden was an act and that he drove a Toyota Corolla as part of his branding. – Discrepancies between FTX’s public and private announcements.
“Mr. Bankman Freed, do you agree that you know how to tell a good story?” asked prosecutor Daniel Sassoon. “I don’t know. It depends on what metrics you use,” he said, without giving a direct answer.
Mr. Sassoon asked about his colleague’s comments. new york timesIn it, Ms. Bankman-Fried claimed that she considered cutting her hair to have negative value because, “I think it’s important that people think I’m crazy.“ From.“ “I don’t think I meant that,” Bankman Fried said.
“Do you consider yourself an intelligent man?” Sassoon pressed.
“Not in all respects, but in many respects,” Bankman-Fried said.
“As CEO of FTX, did you think highly of yourself?”
“Hooray.”
Unrepentant SBF faces decades in prison
During Bankman Freed’s trial, his lawyers pressed him to portray him as a “math nerd who doesn’t drink or party” and is crazy. Prosecutors pushed back against the baby-in-the-woods argument during sentencing submissions, pointing out that he hardly led a life of hardship.
“With all the advantages afforded by a comfortable upbringing, an education at MIT, a prestigious start to a career in finance, and a worthy idea for a start-up business, Bankman Fried was able to achieve the rewards he envisioned.“ “He could have pursued a productive and altruistic life,” they said.
“Rather, his life in recent years has been one of unparalleled greed and arrogance: ambition and rationalization, risk-seeking and repeated gambling with other people’s money.”
In response, Bankman Fried’s team painted him as a victim, writing that prosecutors presented their version of him as a “depraved supervillain.” [with] Dark and megalomaniac motives. ”
“The government seeks to complete the sentence of 32-year-old Sam Bankman Freed,” his attorneys wrote in a statement regarding prosecutors’ 40 to 50-year sentence. “There’s no need to crush Sam like this.”
They, too, suggested a sentence ranging from 63 to 78 months, citing his elite education.
“Offenders with no criminal history, like Sam, are the least likely to reoffend,” they said. “And college-educated offenders are less likely to reoffend.”
In a February petition seeking a reduced sentence, Bankman Fried said there was “zero harm to customers, lenders and investors…The company was solvent at the time of the bankruptcy filing…The money was there.” “It is not lost.”
John Ray, who was appointed FTX CEO to oversee the bankruptcy, denounced Bankman Freed’s claims in a court filing.
“Mr. Bankman Freed continues to live a life of delusion. The ‘business’ he left on November 11, 2022 was neither solvent nor secure. “A large amount of money was stolen by Mr. Bankman Freed,” Ray wrote.
It seems unlikely that they will receive lenient treatment.
Neema Rahmani, president of the West Coast Trial Lawyers Association and a former federal prosecutor, said Bankman Freed “will serve a significant prison term.”
“He refused to accept responsibility and tried to shift the blame onto others. This is one of the greatest
Mike Lynch, known as ‘Britain’s Bill Gates’ and the top technology entrepreneur in Britain, reached the pinnacle of his career when he transformed his software company into an $11bn (£8.6bn) acquisition by a Silicon Valley giant. More than a dozen years later, the acquisition has become the focus of a trial in San Francisco that began last Monday.
Lynch is facing 16 charges of wire fraud, securities fraud, and conspiracy by U.S. authorities, alleging that Hewlett-Packard’s purchase of Autonomy was based on deceitful information. If found guilty, he could be sentenced to up to 25 years in prison. Lynch has pleaded not guilty.
The trial will center on the events of 2011 when HP acquired Autonomy. In the coming weeks, jurors will hear from numerous witnesses in a courtroom directly above the former Autonomy skyscraper site in San Francisco.
Once hailed as “Britain’s Bill Gates,” Lynch spent the first week of his trial quietly listening as federal prosecutors targeted his former empire. He occasionally interacted with his lawyer or worked on his laptop, at times wearing a smile.
1. 2011 Revisited
In 2011, David Cameron was still in office, Barack Obama was president, and movie buffs were enthralled by the final Harry Potter film.
Lynch has consistently claimed that HP mishandled the Autonomy acquisition, leading to its downfall. However, Judge Charles Breyer ruled that the trial’s focus should not include the aftermath of the deal.
Explaining financial transactions and complex arguments from over a decade ago to a new jury presents a significant challenge.
The trial started with the prosecution highlighting a crucial meeting in early 2011 where Lynch allegedly misled HP executives about Autonomy’s success, leading to the $11 billion fraud accusation.
The defense painted Lynch as a tough but brilliant inventor who delegated tasks to talented managers, minimizing his involvement in daily operations.
2. Simplifying the Complex
Government prosecutors accused Lynch of repeatedly lying to investors and auditors, orchestrating a multi-year fraud through deceptive accounting practices.
As the trial progresses, Lynch’s team plans to portray him as a hands-off leader who was unfairly blamed for HP’s struggles and the Autonomy deal.
Historically, the brain was not always recognized as the center of thought. In ancient Egypt, it was believed that the heart held intellect and the soul, resulting in the preservation of the heart in mummified bodies, while the brain was discarded.
In the 5th century B.C., Greek scholar Alcmaion of Croton made claims about the brain, but two centuries later, Aristotle still upheld the belief that the heart was the seat of intelligence.
Octopuses are an interesting example, as about two-thirds of their neurons are found in their tentacles, allowing for semi-independent responses to stimuli. This challenges the idea of a central location for thought.
Advancements in AI models, like ChatGPT, show that conscious thought can be produced without physical sense organs, resembling human thought processes.
While modern neuroscience confirms that the brain controls perception, thinking, and language, cultural and religious beliefs can shape ideas about consciousness and its origins.
In various indigenous cultures, consciousness is often associated with spirits or ancestors, separate from the physical body. Sensations like hunger and pain also demonstrate that thought is not solely contained in the brain.
If our brains and stomachs were reversed, we might view conscious thought as originating in the stomach, with the head serving as a sensory and input location.
This article explores the question of whether we would “think from our stomachs” if our brains were located there, reflecting on the nature of consciousness.

On February 21, a meter-wide space capsule landed in the Utah desert after eight months in orbit. The cargo is a batch of ritonavir, an antiviral drug used to treat HIV and COVID-19.
Carried out by a California startup Varda Space Industries, the mission aims to showcase the potential of automated drug manufacturing in space, potentially opening doors for more efficient ways to develop medications.
Varda’s W-1 mission was launched on a SpaceX Falcon 9 rocket in June 2023. The capsule itself weighs about 90 kg, capable of producing nearly 100 kg of product during several months in orbit.
However, the initial mission produced only a small amount of ritonavir during a 27-hour test run.
In-flight analysis indicates that the manufacturing process was executed as planned, and while final results are pending, Varda is gearing up for its second mission carrying its first commercial payload.

The UK Government has initiated a consultation to gather public and industry input on increasing the legal power of electric bike models from 250W to 500W in the UK. This move has sparked concerns in the fire protection community.
Electric bicycles utilize various types of batteries, with lithium-ion technology being the common choice. These batteries come in different shapes and sizes, such as cylindrical or box-shaped configurations.
Battery packs in electric bikes are composed of multiple cells connected in series and parallel to provide the necessary voltage and capacity. Incidents of fires linked to lithium-ion batteries are on the rise, posing risks to users of electric bikes and e-scooters.
Recent data disclosed in May 2023 by the Guardian newspaper revealed that defective electric bikes and e-scooters have caused injuries to 190 individuals and claimed eight lives in the UK. The London Fire Brigade noted a substantial increase in battery-related fires in 2023, with a rise of 78% compared to the previous year.
Potential causes of fires in lithium-ion batteries include mechanical or thermal shock, overcharging, and reactive materials interacting with each other, leading to heat generation and abnormal electrical behavior. Despite the benefits of higher wattage batteries in electric bikes, there are concerns about the increased risk of fires and other safety issues.
To mitigate the risk of battery fires, users are advised to avoid tampering with batteries, charge them within the recommended parameters, and store them in a safe environment away from flammable materials. Adherence to manufacturer guidelines and proper disposal of damaged batteries are crucial in preventing incidents of fires.
NASA stays in touch with its space probes, like Voyager 2, through the Deep Space Network (DSN), which consists of radio receiving antennas located in three different spots globally. These locations include Goldstone in California, Robredo near Madrid, and Tidbinbilla near Canberra.
Voyager 2 can only be observed from the southern hemisphere, making the DSS-43 antenna at the Australian site the sole antenna on Earth that can communicate with the spacecraft.
Currently positioned more than 20 billion kilometers from Earth, Voyager 2 has a transmitter that outputs approximately 23 watts (around eight times more powerful than a typical cell phone). By the time a radio signal reaches Earth, it has only about one-tenth of this power.
undefined
To detect this extremely faint signal, DSS-43 and Voyager 2’s transmitters use narrowband, high-frequency signals that are highly directional and transmitted at slow bit rates.
Advanced signal processing techniques, minimal interference, and the fact that radio signals can travel through space with little obstruction allow DSS-43 to overcome long distances.
The antenna can transmit a signal to Voyager 2 at a much higher power level (up to about 400,000 watts) than it receives. This strong output can be easily picked up by the spacecraft even at far distances.
This piece (by Elouise Pace) addresses the question, “How can we communicate with Voyager 2, which is billions of miles away?”

When something strange happens in your neighborhood, who do you call? Most likely, the police, as ghosts and Ghostbusters are not real. However, that doesn’t stop people from believing in the paranormal.
“It tends to be driven by two factors,” says Richard Wiseman, Professor of Public Understanding in Psychology at the University of Hertfordshire. “One is personal experience. Many claim to have experienced paranormal phenomena after losing a loved one.
“The second factor is popular media. Most experiences are easily rationally explained. For instance, phenomena like double exposures in photography used to be common but have decreased with the rise of camera phones, making ghosts less common.”
Wiseman explains that both drivers tap into various psychological traits, some universal and others unique to certain individuals.
“Humans have imaginative minds,” he says. “We seek to imagine a world free of pain and suffering, where loved ones are still present. We are creatures that seek patterns, but sometimes we overwork ourselves and see patterns that aren’t real.”
Wiseman connects belief in ghosts to creativity. For example, a 2013 study at the University of British Columbia found that people are more likely to attribute human characteristics to non-human objects, making them more likely to believe in ghosts.
“Those who believe in such phenomena typically share similar psychological traits,” Wiseman notes. “They are open-minded, creative, and excel at immersing themselves in experiences like plays and movies, identifying patterns.”
However, one can harness this inherent creativity. A study by psychologist Dr. James Horan in the 1990s found that people were more likely to believe in the paranormal when “primed,” a psychological term describing how one stimulus affects subsequent stimuli.
“He took two groups around disused movie theaters,” Wiseman elaborates. “One group was told it was an architecture tour with nothing out of the ordinary, while the other group was told it was haunted. As a result, the latter group began experiencing phenomena. Ambiguity and suggestions can influence how we perceive and report experiences. Psychics often utilize this technique.”
The power of human beliefs can shape our reality, sometimes leading to belief in foolish things like ghosts or harmful notions like conspiracy theories. Yet, Wiseman chooses to focus on the positive aspect of this phenomenon.
“When we consider great scientific achievements like landing a man on the moon or developing a coronavirus vaccine in record time, we realize the power of belief in achieving near-impossible feats. Despite sometimes being led astray by ghosts, we can achieve remarkable things through belief, even with minimal evidence. That’s the trade-off for greatness.”

The newly identified structures, called Shakti and Shiva, are between 12 billion and 1 billion years old, making them so old that they are even older than the spiral arms and oldest parts of the present-day Milky Way galaxy's disk. may have been formed before.
This image shows the location and distribution of Shakti (yellow) and Shiva (blue) stars throughout the Milky Way. Image credit: ESA / Gaia / DPAC / K. Malhan.
“What's really amazing is that we can detect these ancient structures at all,” said Dr. Kati Malhan, an astronomer at the Max Planck Institute for Astronomy.
“The Milky Way has changed so much since these stars were born that we didn't expect to be able to see them so clearly as a group. But the unprecedented data obtained from ESA's Gaia satellite Thanks to you, this is possible.”
Using Gaia observations, Dr. Mulhan and Dr. Hans-Walter Rix of the Max Planck Institute for Astronomy were able to determine the orbits of individual stars in the Milky Way, as well as their content and composition.
“When we visualized the orbits of all these stars, we found that two new structures stood out from the rest among stars of certain chemical compositions. We named them Shakti and Shiva. '' said Cati.
Each stream contains the mass of about 10 million suns, and the stars, all 12 to 13 billion years old, have similar compositions and move in very similar orbits.
The way they are distributed suggests that they may have formed as separate pieces that merged with the Milky Way early in their lives.
Shakti and Shiva both lie towards the center of the Milky Way.
Gaia explored this part of the Milky Way in 2022 using a type of galactic archaeology. This indicates that this region is filled with the oldest stars in the entire galaxy, all of which were born before the Milky Way disk was properly formed.
“The stars there are so old that they lack many of the heavy metal elements that were created later in the life of the universe,” Dr. Ricks says.
“Because the stars at the center of our galaxy are metal-poor, we named this region the 'poor old heart' of the Milky Way.”
“Until now, we were only aware of very early fragments that came together to form the ancient core of the Milky Way.”
“In Shakti and Shiva we see the first works that appear to be relatively ancient but are located further out.”
“These represent the first steps in the galaxy's growth towards its current size.”
The two streams are very similar, but not identical. The star Shakti orbits a little farther from the center of the Milky Way galaxy and has a more circular orbit than the star Shiva.
Fittingly, these streams are named after the divine couple in Hindu philosophy who come together to create the universe.
About 12 billion years ago, the Milky Way was very different from the orderly spiral we see today.
They believe that our galaxy was formed by the merging of multiple long, irregular filaments of gas and dust that all formed stars and intertwined, giving rise to the galaxy as we know it. It is being
Shaki and Shiva appear to be two of these components, and future Gaia data releases may reveal more.
The authors also created a dynamic map of other known components that play a role in galaxy formation and were discovered using Gaia data.
These include Gaia-Sausage-Enceladus, LMS1/Wukong, Arjuna/Sequoia/I'itoi, and Pontus.
These groups of stars all form part of the Milky Way's complex genealogy that Gaia has been working to build over the past decade.
Dr Timo Prusti, ESA astronomer and Gaia project scientist, said: “Learning more about the early life of the Milky Way is one of Gaia's goals, and we are well on our way to achieving it.”
“To understand how our galaxy formed and evolved, we need to pinpoint subtle but crucial differences between the Milky Way's stars.”
“This requires incredibly accurate data, and now, thanks to Gaia, we have that data.”
“As we discover surprising parts of our galaxy, such as the Shiva and Shakti rivers, we are filling in the gaps and painting a complete picture not just of our current homeland, but of the earliest history of the universe.”

International trade may have helped medieval elites obtain the best horses for jousting tournaments
Prisma Archive / Alamy
Analysis of horse teeth unearthed in a London cemetery suggests that the horses owned by medieval England's elite were likely imported from continental Europe and may have traveled hundreds of kilometers.
In the 1990s, a commercial excavator accidentally discovered an unusually large horse burial ground in central London. Subsequent excavations at the site, now known as Elberton Street Cemetery, uncovered the full or partial remains of 70 horses. Some graves date him from 1425 to 1517, but the cemetery may have been in use over a wider period.
“This is a great example of the only true horse cemetery in medieval England,” he says. Oliver Clayton at the University of Exeter, UK. “We usually [horse remains] Very few are scattered on archaeological sites. ”
To learn more about the origins and lives of these medieval horses, Creighton and his colleagues collected and analyzed molars from 15 horses buried at the site.
Plants from different parts of the world contain different levels of carbon, oxygen, and strontium isotopes, or atoms with different numbers of neutrons. When animals eat these plants, these isotopes accumulate in their bones and teeth over time. By analyzing the chemical signature of the horse's teeth, the researchers were able to determine where it likely came from.
It said this revealed that at least seven people came from abroad, possibly from Scandinavia or the Western Alps. alexander pryoralso at the University of Exeter.
“These were also the largest medieval horses ever discovered in Britain,” Pryor said, noting that Britain's elite may have sought out the best horses from Europe. Suggests.
The arrangement of their teeth seemed to suggest the use of special mouthpieces normally reserved for horses groomed for combat and jousting tournaments.
“The horse likely came from the equestrian arena at the Palace of Westminster, just a kilometer away,” Clayton said.
“The nature of horse teeth, with their very tall crowns growing over many years, offers great potential for research using isotopes to track the movements of individual horses over their lifetime,” he said. To tell. david orton At York University, UK. “But this is the first paper I've seen that seems to take full advantage of that potential.”

Instruments aboard a NASA spacecraft scheduled to launch to Europe later this year could directly detect cellular material ejected from Jupiter’s icy moons, increasing the chances of finding life.
Europa is of scientific interest because researchers believe there is a vast saltwater ocean beneath its thick icy shell. It is also surrounded by an orbiting blanket of ice grains and dust, believed to be the remains of material kicked up after the meteorite struck.
NASA’s Europa Clipper spacecraft was launched in October and is scheduled to arrive at its destination in 2030, flying close to the moon but not landing on it. Ten experiments will be carried out aimed at studying Europa’s internal structure, including its ocean chemistry and potential habitability for extraterrestrial life.
One of these is the SUrface Dust Analyzer (SUDA), a type of instrument known as a mass spectrometer. The mission will collect material ejected from the moon and reveal its chemical composition, including potential organic molecules and salts.
SUDA was not designed to look for signs of life in Europe, but now Frank Postberg and his colleagues at Germany’s Freie Universität Berlin, who are working on the device, have shown that it can detect fragments of cellular material, potentially providing evidence of modern life.
“If life on Europa follows the same principle of having membranes and DNA made from amino acids… [those chemicals] “It will be the deciding blow of my life,” he says.
“This is an interesting result because these ice grains hit the instruments in space at speeds of 4 to 6 kilometers per second,” say team members. Fabian Krenner at the University of Washington. “We showed that we can still identify cellular material.”
These extreme velocities cause particles to collide with SUDA with high kinetic energy, breaking large molecular structures into smaller component parts for analysis. To simulate this kinetic energy, the team shot water droplets with a laser. I put the following sample into water. Sphingopyxis alascensisa bacterium known to survive in frigid marine environments, making it a potential alternative to life on Europa.
When the laser hits the droplet, it breaks up into tiny droplets that hit the SUDA detector. The researchers discovered that they could distinguish between fragmented cellular material, including fatty acids and amino acids, which are abundant in cell membranes.
“We have now simulated the presence of cells inside a single ice grain without any pretreatment, which may be a valid case for what we see in Europe,” Klenner said. To tell. The next step, he says, is to repeat the experiment using different types of cell cultures.
Murti Gudipati He works on SUDA at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., but is not involved in the research. The results should reflect what could happen to the spacecraft, he said. Watch while on duty.
But the ability to clearly distinguish cellular material from other organic molecules and salts depends on the specific composition of the ice grains released from Europa, he says. If SUDA detects many other complex organic molecules and salts mixed in with the ice grains, it may be difficult for researchers to reliably detect cellular material, Gudipati says.
the current, NASA says When asked, “Europa Clipper is not a life-detecting mission. Its primary science goal is to determine whether there is a place beneath Europa’s surface where life could exist.” new scientist The agency was unable to respond prior to publication about whether the new research changes the mission’s goals.
Astronomers used NASA’s Chandra X-ray Observatory and NSF’s Carl G. Jansky Very Large Array (VLA) to locate H1821+643, the closest quasar hosted by a galaxy cluster, about 3.4 billion light years away. The quasar was found to be more powerful than many supermassive black holes in other galaxy clusters.

Quasars are a rare and extreme class of supermassive black holes that violently pull matter inward, producing intense radiation and sometimes powerful jets.
This quasar, known as H1821+643, is about 3.4 billion light-years from Earth and contains a black hole with a mass of 4 billion solar masses.
Most growing supermassive black holes pull matter in at a slower rate than quasars.
Astronomers have been studying the effects of these more common black holes by observing black holes at the centers of galaxy clusters.
Periodic explosions from such black holes prevent the massive amount of superheated gas embedded in the black hole from cooling down, increasing the number of stars forming in its host galaxy and the fuel pouring toward the black hole. limit the amount of
Little is known about how much influence quasars within galaxy clusters have on their surroundings.
“Our research shows that quasars appear to have given up much of the control imposed by slower-growing black holes. The appetite of black holes is unmatched in their influence,” Nottingham said. University astronomer Dr Helen Russell said.
To reach this conclusion, Russell and his colleagues used Chandra to study the hot gas surrounding H1821+643 and its host galaxy.
But the bright X-rays from quasars have made it difficult to study the weaker X-rays from hot gases.
“To reveal the effects of a black hole, we had to carefully remove the X-ray glare. Then we found that it actually had little effect on its surroundings,” says Harvard University. said Dr. Paul Nalsen, an astronomer at the Smithsonian Center for Astrophysics.
Using Chandra, astronomers discovered that the density of gas near the black hole at the center of a galaxy is much higher than in more distant regions, and the temperature of the gas is much cooler.
Researchers believe that when there is little or no energy input (usually from an explosion from a black hole), hot gas behaves this way to prevent it from cooling and flowing toward the center of the cluster. Expect.
“The supermassive black hole generates far less heat than other black holes at the center of galaxy clusters. This allows the hot gas to cool rapidly and form new stars, which fuel the black hole. It also acts as a source,” said Dr Lucy Crews, an astronomer at the Open University.
The researchers determined that the equivalent of about 3,000 solar masses per year of hot gas has cooled to the point where it is no longer visible in X-rays.
This rapid cooling easily supplies enough material for the 120 solar masses of new stars observed to form each year within the host galaxy and the 40 solar masses consumed by black holes each year. be able to.
The scientists also investigated the possibility that radiation from quasars directly causes cooling of the cluster's hot gases.
This involves photons of light from the quasar colliding with electrons in the hot gas, increasing the energy of the photons and causing the electrons to lose energy and cool down.
This study showed that this type of cooling is probably occurring within the cluster containing H1821+643, but is too weak to explain the large amount of gas cooling seen.
Dr Thomas Braben, an astronomer at the University of Nottingham, said: “This black hole may not be producing enough because it isn't pumping any heat into its surroundings, but the current situation won't last forever.'' ” he said.
“Ultimately, the rapid uptake of fuel by the black hole should increase the jet's power and strongly heat the gas.”
“After that, the growth of the black hole and its galaxy should slow down significantly.”
“Ash light” or AL is a faint mysterious glow or hue seen in the night hemisphere of Venus. It is often compared to Earthshine, the reflected light that illuminates the far side of the Moon.
First described by Italian astronomer Giovanni Riccioli in 1643, AL has been observed many times since then, but its faint, ephemeral, and elusive nature has prevented serious research. It’s here.
Even more problematic, AL has so far only been detected by the human eye, and no scientific instruments, either earth-based or space-based, have recorded this phenomenon.
Some authorities have declared this phenomenon to be an illusion, perhaps an eye contrast effect or even an “expectation bias.” Some have suggested that a defect in the equipment could explain the phenomenon. Light scattering, optical aberrations, background sky brightness, weather, etc.
But there are enough reliable reports about AL that some scientists can offer an explanation. These include reflected light from Earth, auroras, “airglow” radiation, lightning, and infrared (thermal) radiation from Venus’ atmosphere.
Most of these explanations are ignored for some reason. However, there is ample evidence that not only ultraviolet light from the sun, but also high-energy solar wind particles can excite oxygen atoms in Venus’ atmosphere.
This creates a pale green glow similar to that seen in the aurora borealis on Earth. However, the process is somewhat different because auroras on Earth are caused by Earth’s magnetic field interacting with solar particles, whereas Venus has no appreciable magnetic field.
It remains to be seen whether this explanation can explain all or some of the AL observations. Therefore, the long-standing mystery of AL may still turn out to be an illusion.

Records of dogs’ brain activity show that dogs seem to understand that words refer to specific objects.
Some dogs can retrieve a variety of objects on command, but few do well in such tests in the lab. Additionally, it is unclear whether dogs understand words as names of objects rather than instructions.
To explore this question further, Marianna Boros Researchers at Eötvös Lorand University in Budapest, Hungary, tested 18 dogs from a wide range of breeds, including border collies, toy poodles and Labrador retrievers.
Owners selected five objects that were familiar to each dog. In the test, they said the name of an object and showed the dog either the named object or another object.
Each dog’s brain waves were monitored using electroencephalography (EEG) to see if there was a difference in activity compared to when the word and object were the same, such as when the dog’s owner said “ball” and showed a stick. Ta.
“The idea was that if dogs understood the meaning of words, their brains would respond differently when presented with matching objects than when presented with mismatched objects,” Boros says.
The researchers found that the brainwave signals were different when the objects did not match, and that the effect was stronger for words that the individual dogs were familiar with. This is similar to results seen in humans and suggests that dogs know that certain words represent certain objects.
“The most important takeaway from this study is not only that non-humans have the ability to understand words referentially, but also that this ability appears to be present in dogs in general as well,” Boros said. says. “This study shows that dogs may understand more than they show.”
No one breed of dog seemed to exhibit better language skills than the other, Boros said.
susan hazel Researchers from the University of Adelaide in Australia say their study adds to our knowledge of dog cognition.
“I think both dogs understand more than we realize,” says Hazel. “This study shows that dogs seem to have mental representations of words they know, such as ball. This shows how dogs understand some words. This is no surprise at all to most dog owners.
On the other hand, many dog owners anthropomorphize their pets, ascribing emotions and understanding abilities to them that don’t exist, she says.
“Canine cognition is currently one of the most researched areas in the world,” says Hazell. “I love all the research about dogs, but I’d also like to learn more about the other animals we live closely with: cats, rabbits, horses.”
Living a healthier life can be achieved in many ways. Simple activities like daily walks, healthy eating, and brain-boosting puzzles like Sudoku can keep your mind and body active. For a unique approach, consider trying neuromodulation, which involves sending electric shocks to the brain.
Neuromodulation is an innovative method that uses a stimulator placed on the head to deliver electrical shocks directly to the nervous system. This non-invasive technique offers numerous health benefits and has gained traction as a cutting-edge technology for enhancing well-being.
The concept of neuromodulation has been around for some time, but companies like Parasin and gamma core have reignited interest in recent years. These companies claim to improve mental performance and overall health with their devices that can be used conveniently at home.
Research from reputable institutions like UCL, Harvard University, and University College London supports the effectiveness of neuromodulation. Even tech entrepreneurs like Brian Johnson have shown interest in this technology.
What is neuromodulation and how does it work?
Neuromodulation is a technique that alters neural activity by delivering electrical signals to specific areas. Imagine it as a dimmer switch that can increase or decrease nerve or brain activity. This method can excite or inhibit nerves to alleviate pain and modify neural patterns associated with various conditions like epilepsy and Parkinson’s disease.
Companies like Parasym use “auricular vagal neuromodulation therapy” to deliver electrical signals through the ear to target the vagus nerve, which plays a crucial role in connecting the brain, heart, and digestive system.
How technology can slow aging
Neuromodulation can help slow down the aging process by combating chronic inflammation, enhancing cognitive function, and improving cardiovascular health. Research shows promising results in addressing age-related issues like Alzheimer’s disease and heart conditions.
While neuromodulation offers benefits like improved heart rate variability and reduced fatigue and depression, it remains in the early stages of development. Safety concerns and experimental results underscore the need for further research and validation.
Is neuromodulation safe?
Neuromodulation has evolved since its inception in the 1960s, with modern devices providing safer options for users. Implantable devices offer more effective treatment but come with higher risks, including infections and other complications.
Non-invasive wearable devices like those from Parasym are considered safer, with minor side effects like skin irritation being the main concern. These devices require consistent use to deliver optimal results, making them a more accessible but less durable alternative to implantable devices.
While neuromodulation technology shows promise in improving health and well-being, users should weigh the benefits against the costs and potential risks before investing in these innovative devices.
A colony of black garden ants in a nest with several eggs, pupae, larvae and a large queen bee

When a black ant queen notices that her young are sick, she eats them before the disease spreads to other parts of the nest.
Cannibal queens may not win the “Mother of the Year” award, but research suggests this strategy could be an effective way to protect the kingdom. The findings provide insight into the evolution of “filial cannibalism,'' the practice of parents consuming their children.
Ants and other colony-dwelling social insects can prevent the spread of disease by forcing workers to self-isolate when they become sick and by eliminating infected nestmates. These “social immunity” obligations are well known, he writes. Flynn Bizzell and christopher pull at Oxford University. But since the ant queen starts colonies alone, how does she protect herself from disease as she builds and grows her nest?
To find out, Bizell and Puru collected newly mated black ants (Lasius Niger) took the queen to the laboratory. Once the ants had laid eggs and started building nests, the researchers removed the larvae from the queen and exposed some to deadly ant spores. Metahydium A fungus that infects wild ant nests. After a period of time during which these larvae developed a potentially fatal infection, the researchers returned all of the larvae to their mothers, even though they were not yet contagious.
The queen ate 92 percent of the diseased larvae, but only 6 percent of the larvae were uninfected, indicating that the queen was able to detect infection and intervene. Failure to catch the infection can have dire consequences. When the researchers exposed the colonies to the carcasses of highly infectious larvae that had sprouted spore-producing fungi, all the larvae died. And even after spraying the carcasses with an acidic antibacterial toxin, only 20 percent of the queens survived.
Despite these risks, queen bees that feed on infected larvae appear to avoid harm. Researchers suggest that queen bees may be ingesting their own antimicrobial toxins to make their intestines hostile to fungal spores. Based on this conclusion, they Observation of worker ants before they swallow the poison The team then observed the queen bee tending to the openings of her venom glands.
“If the queen gets infected and dies, the colony dies as well,” he says. sebastian stockmeyer She is at the University of Tennessee, Knoxville, as she is the only one with the ability to reproduce. Therefore, it makes sense that evolved strategies to deal with disease would emphasize queen survival.
There are other benefits to eating sick babies as well. The researchers found that queens that ate sick offspring laid 55% more eggs than queens that did not, suggesting that they recycled these caloric resources. The researchers argue that this benefit and the elimination of disease risk could indicate how filial cannibalism evolves in some species.
Joel Meunier Researchers at the University of Tours in France believe that offspring that hatch after their older siblings are eaten may have immune systems that better protect against fungal infections. If so, proving this may reveal the “double benefit” of filial cannibalism for both mother and offspring.
This finding suggests that there is overlap in the behaviors needed to care for young and prevent disease in young colonies. As a result, Bizell and Pule argue that workers' disease prevention behaviors may have evolved from common parental care found in many types of insects.
An uncommon cosmic eruption is set to happen in the Milky Way galaxy soon, resembling the appearance of a “new” star in the night sky for a brief period.
Referred to as Nova, this event presents a unique sky-watching opportunity for individuals in the northern hemisphere. NASA states that such explosions occur infrequently in our galaxy.
This stellar eruption will take place in the T Coronae Borealis star system, situated 3,000 light-years away from Earth. This system consists of two stars, one being a deceased star, or “white dwarf,” orbiting near a red giant star that is nearing the end of its life cycle. According to NASA, our solar system’s sun will face a similar fate.
In systems like T Coronae Borealis, the proximity between the two stars causes material from the red giant to overflow onto the white dwarf’s surface over time. This leads to a buildup of pressure and heat, culminating in an eruption.
“The buildup of material on the white dwarf’s surface results in increased temperature and pressure until it eventually explodes. It’s a runaway reaction,” explained Bradley Schaefer, a retired physics and astronomy professor from Louisiana State University.
Schaefer likened a nova explosion to a hydrogen bomb detonating in space, creating a visible fireball from Earth’s perspective. (Not to be confused with a supernova, which occurs when a massive star collapses and dies.)
At the peak of the eruption, it should be visible to the naked eye, making it easy to observe from your backyard, Schaefer stated.
Astronomers anticipate the nova explosion happening between now and September. The last eruption from this system occurred in 1946, with the next expected eruption in about 80 years.
Astronomers worldwide are monitoring the North Star system for activity. If an eruption is detected, it could quickly reach a brightness similar to Polaris in less than 24 hours, offering a spectacular view. The explosion might remain visible to the naked eye for several days before fading.
According to NASA, skywatchers could potentially spot the eruption for around a week after dark using binoculars.
NASA
Typically too faint to be seen with the naked eye, T-corona systems can be identified by looking for the constellation or northern cap. This constellation forms a small semicircular arc between Hercules and Boes.
Schaefer, who extensively researched the T Coronae system, encourages catching a glimpse of this incredible phenomenon.
“This system has a recurrence time scale of less than 100 years, with most cycles lasting around 1,000 years,” he stated.
In a recent publication by the Astronomical History Journal, Schaefer unveiled two previous “long-lost” Ti Coronae Borealis eruptions from historical records, observed in 1217 by a German monk and in 1787 by English astronomer Francis Wollaston.
Schaefer shared a historical anecdote, recalling the monks near Augsburg, Germany, describing such an eruption as a significant yearly event, even naming it “signum mirabile,” which translates to ‘great omen’ in Latin. It was considered a favorable omen.
Yet, predicting the exact viewing period for this “wonderful omen” presents a challenge.
“This event could happen tonight,” Schaefer stated. “Most likely in the next few months, possibly by the end of summer.”

“I remember rushing home from school just to play Rollercoaster Tycoon,” says Merlin Entertainments, the owner of UK-based theme parks including Olton Towers, Chessington World of Adventures, and Legoland Windsor. John Burton, senior creative lead at Yahoo! He is designing the 72-meter (236-foot) Hyperia roller coaster planned for Thorpe Park. “Then I went to sleep dreaming of being the next Walt Disney.”
As an adult, Burton looks back on the game with the excitement of a teenager on a sugar high. “I learned so much about how roller coaster systems work with block zones and even little tricks at theme parks like adding side cues and strategically placed restrooms,” he said, continued, confirming my suspicions that a Jumanji-themed jungle world was his idea. The piece, which Chessington helped design, has what he calls “subliminal similarities” to his Jolly Jungle scenario from the classic PC game. “When I have to go to a theme park overseas for work, I still load the original game onto the plane and sketch out ideas. I never really stopped playing.”
John Burton of Chessington World of Adventures…he grew up playing on rollercoasters and now designs real-life rides.
Released 25 years ago today, RollerCoaster Tycoon (the best-selling PC game of 1999) was a viral success before online virality was established, with users sharing their favorite real-world designs and recreations. It has inspired countless geosite forum communities. vehicle. These communities still exist, and one designer recently created a nightmarish existential roller coaster that took him 12 years to cringe. complete.
The 1999 theme park strategy game RollerCoaster Tycoon sold 700,000 copies in its first year and helped keep publisher Atari afloat. Today is its 25th anniversary. RollerCoaster Tycoon not only provided millions of fans with an endless toolbox of fun to build the theme park of their dreams (more on that later), but the entire adjacent theme park industry. He has solved the mysteries of men and contributed to reducing the male-dominated industry.
“I remember for many years I was the only woman working on roller coaster projects,” says Legoland Resort Executive Creative Director and creator of the world’s first vertical drop roller coaster at Alton Towers, says industry heavyweight Candy Holland, who helped design Oblivion. “But when Roller Coaster Tycoon came out, there was a sudden surge in young women applying for jobs. I think I had a deeper understanding.”
One of those young women was Flora Louie, a senior project manager for Merlin’s “Magic Creation” team in California. She argues that unlike many games of the time (Resident Evil, GoldenEye 007), Roller Coaster Her Tycoon attracted male and female players because it traded the fantasy of death and destruction for fun creativity. . “Playing Rollercoaster Tycoon was radical,” she says.
“Graphic styles are now seen as quirky and unique, rather than as outdated and restrictive as they were back then,” says Roller Coaster Tycoon designer Chris Sawyer. Photo: Atari
“I remember changing the color so that all the rides were pink. We spent a lot of time creating maze-like lines, making the customers laugh and confuse them, and even telling our parents that all the designs were different.” As a project manager, I have to consider the push and pull of the budget; the impact of increased visitor numbers; safety; managing the flow of guests and delivering the magic; As I’m participating, I’m thinking about all these things and remembering how Roller Coaster Tycoon set me on this path.”
From tranquil lush lakes to more exhilarating Haunted Harbor and Diamond Heights, each of the game’s 21 scenarios is a theme park where you can find quick solutions to dilemmas and give pixelated attendees the time of their lives was intended to create. “The success of this game really kept Atari in business,” admits Atari CEO Wade Rosen. “The fact that you can build these very complex roller coasters and you can completely ignore all of them and launch them. [customers] It was really genius to jump into the lake and see how many fish you could gag. ”
Rosen claims that everyone who played it had a “different experience” and said that the canvas of creativity that existed in Rollercoaster Tycoon was essentially a prototype for what would become Minecraft. He was a ruthless player in capitalism, he says. “I really liked the business side of it…When it was raining, I would put a price on an umbrella right away. It’s like $20 now. And I brought a lot of cash. Sho.”
This mesmerizing shot of the perfect alignment of the sun and full moon over Utah's Valley of the Gods last October is raising expectations for next month's total solar eclipse in North America.
This image, a collaboration between photographers Andrew McCarthy and Daniel Stein, shows an annular solar eclipse in which an outer “ring of fire” forms because the moon is too far from Earth to completely cover the sun. I am. The shot is the result of digitally stitching together thousands of images, combining Stein's landscape photography skills with McCarthy's experience capturing images of the sun.
After months of planning, the pair set up cameras and telescopes at carefully selected desert locations to capture the key shots, taking into account weather patterns, eclipse duration, and terrain features. did.
The image was published by Social media March 8th, exactly one month before a total solar eclipse, in which the moon completely covers the sun, will pass over North America. It will blanket much of the continent in darkness or completely, from Canada to the United States and Mexico. The path of the total eclipse will be much wider than the last similar solar eclipse in the region, covering almost 200 kilometers compared to about 115 kilometers in 2017.
“It’s easy to take the sun for granted, but [sun and moon] When combined during a solar eclipse, they are breathtakingly beautiful. I feel that incorporating landscape elements adds a sense of grounding to the images and allows the viewer to connect more deeply with the work,” says Stein.
Starbucks has been actively resisting unionization efforts for over two years, but now they seem willing to engage in negotiations.
In a surprising move, Starbucks and its union released a joint announcement at the end of February, expressing a willingness to make progress on organizing and collective bargaining.
The union representing Starbucks employees announced plans to resume direct negotiations with the company in late April to establish a basic framework agreement involving over 400 unionized stores.
This development has brought hope not only to Starbucks employees but also to workers at companies like Amazon, Trader Joe’s, and REI, who have been struggling to move contract negotiations forward.
The possibility of Starbucks potentially unionizing after years of aggressive anti-union tactics has sparked curiosity about which company may follow suit in the future.
Claire Chan, an REI employee, expressed excitement about the progress, highlighting the persistence required to bring a company like Starbucks to the negotiating table. She described it as a significant step forward.
John Logan, a labor studies professor, remains cautious about Starbucks’ intentions and whether they will truly commit to ending anti-union practices and reaching an initial contract.
The union representative for Starbucks, Michelle Eisen, remains optimistic about the future collaboration between Starbucks and the union, emphasizing the importance of valuing employee input for business success.
Starbucks has offered a settlement to the union following backlash over union-busting allegations, stock price declines, and disruptive strikes, showing a potential shift towards supporting unions.
Legal experts and union representatives see Starbucks’ possible unionization as a significant step that could inspire other companies to consider similar actions.
Overall, the announcement from Starbucks has far-reaching implications for workers’ rights and the future of unionization in major corporations.
A brown male Thomisus guangxicus Spider (center) in a Hoya pandurata flower with a pale amber female just below it.
Wu Shimao
A species of spider discovered in China may have evolved a male-female pair that looks like a flower, allowing it to blend into the background.
“This may be the world's first case of cooperative imitation,” said Shi-Mao Wu of Yunnan University, who observed it with colleagues. Jiang Yun Gao.
Spiders of the family Tomicidae, also known as crab spiders, are ambush predators that usually live on or near flowers.
They are known for their excellent camouflage abilities that prevent them from being detected by prey or predators. Some species can even change color to match the color of the flower they sit on.
Wu and Gao were in the rainforest of southwestern China's Yunnan province when a male crab spider attacked them. Tomysus guanxicus Something caught Mr. Wu's attention.the spider was sitting on the flower Hoya pandurataa plant that lives on ancient tea trees in the forest.
“The first time I observed a male spider, I didn't see a female spider,” Wu said. Only when I got closer did I notice that the male spider was lying on the female's back. “They tricked my eyes really well,” he says.
Researchers hypothesize that the small, dark-colored males mimic pistils (female organs in the center of flowers), while the females mimic fused petals.
Researchers say that only when individual spiders of both sexes come together will the flowers match in appearance.
but, Gabriele Greco A professor at the Swedish University of Agricultural Sciences is not convinced. “It's very difficult to determine the nature of the observed behavior,” he says.
In fact, in many spider species it is common for the male to stand over the female during mating. “A simpler explanation might be simple interactions related to courtship and mating,” Greco says.
The social media platform Reddit’s stocks, traded under the symbol RDDT.N, closed the first day of trading in New York with a 48% increase. This suggests that there is renewed investor interest in initial public offerings (IPOs) of promising yet money-losing companies.
Reddit’s shares closed at a value 48% higher than their initial offering price on the first day of trading, valuing the company at over $9 billion. The stock rose to $57.80 per share, a 70% increase, before settling at $50.44 per share by the day’s end.
The IPO price for the San Francisco-based company was $34 per share, giving it a market value of $6.4 billion. The company and its selling shareholders raised $748 million.
Reddit’s highly anticipated IPO had been in the works for over two years. An IPO filing was made secretly in December 2021 but was delayed due to market volatility. The current valuation marks a decrease from 2021 when it was valued at $10 billion in a private funding round.
Reddit’s strong market entry could yield significant gains for its largest shareholder, Advance Publications. The parent company of Condé Nast, which owns magazines like The New Yorker and Vogue, stands to profit up to $1.4 billion from the IPO. Advance purchased Reddit for $10 million just 18 months after its launch.
Reddit’s co-founder and CEO, Steve Huffman, received a compensation package totaling $193 million last year. While the site’s other co-founder, Alexis Ohanian, has been a public figure, he does not appear in the company’s filings with U.S. financial regulators.
Major shareholders of Reddit include Chinese gaming company Tencent with an 11% stake, Fidelity with 9.5%, and OpenAI CEO Sam Altman with 8.7%. Reddit was part of the first batch of startups from Y Combinator, where Mr. Altman later served as president.
Reddit’s IPO amid a tech frenzy is expected to give the company a strong market position. However, Julian Klimochko, CEO of Accelerate Financial Technologies, suggests that market performance in the coming weeks will be closely monitored.
“A poor trade by Reddit could impact the IPO market, leading many companies to pause their IPO efforts,” Klimochko stated.
Since its founding in 2005, Reddit has become a cornerstone of social media culture, known for its alien logo on an orange background and its tagline “Front Page of the Internet.”
Reddit hosts over 100,000 online forums called “subreddits” covering a wide range of topics. The platform has been used for various activities, including support groups and interviews, such as the one conducted with Barack Obama in 2012.
Despite its cult status, Reddit has not matched the success of larger rivals like Facebook and Tesla. The company has about 73 million daily unique visitors compared to Facebook’s 2 billion daily logins.
Reddit allocated 8% of its IPO shares to eligible users, moderators, board members, and acquaintances of employees and directors as part of its user appreciation plan. The company is in early stages of monetization and has yet to turn a yearly profit, raising questions about its path to profitability.
“The true test will be after the first earnings report. The results and strategic changes made post-IPO will be crucial,” said Leena Agarwal, director of Georgetown University’s Psaros Center for Financial Markets.

“Such radio bursts were detected about 40,000 kilometers (25,000 miles) above sunspots (relatively cool, dark, magnetically active regions of the Sun) that had previously been observed only on planets and other stars. It was done.”
On other planets like Earth, Jupiter, and Saturn, auroras sparkle in the night sky when solar particles get caught up in the planet's magnetic field and are pulled toward the poles where the magnetic field lines converge.
As the particles accelerate toward the poles, they generate powerful radio emissions at frequencies around a few hundred kilohertz that collide with atoms in the atmosphere and emit light as auroras.
The research team's analysis shows that radio bursts on sunspots likely occur in a similar way, when high-energy electrons are captured and accelerated by magnetic fields converging on sunspots. It suggests.
However, unlike Earth's aurora borealis, the radio bursts from sunspots occur at much higher frequencies, from hundreds of thousands of kilohertz to approximately one million kilohertz.
“This is a direct result of the sunspot's magnetic field being thousands of times stronger than Earth's magnetic field,” Yu says.
Similar radio emissions have been previously observed from several types of low-mass stars.
This discovery raises the possibility that auroral-like radio emissions originate from large spots on these stars, in addition to previously proposed polar auroras.
“This discovery excites us as it challenges existing concepts of solar radio phenomena and opens new avenues for exploring magnetic activity both in the Sun and in distant star systems. ” said Dr. Yu.
“NASA's ever-growing heliophysics fleet is well suited to continue investigating the source regions of these radio bursts,” said NASA Goddard Space Flight Center heliophysicist and solar radio researcher. said Dr. Nachimthuk Gopalswamy.
“For example, the Solar Dynamics Observatory continuously monitors the active regions of the Sun, which could be causing this phenomenon.”
In the meantime, the authors plan to review other solar radio bursts to see if any resemble the aurora-like radio bursts they discovered.
“We aim to determine whether some previously recorded solar outbursts may be examples of this newly identified emission,” Dr. Yu said.

Pebanista Yacluna About 16 million years ago, it lived in the Miocene Amazon of Peru.
The ancient dolphin was estimated to be 2.8–3.5 m (9.2–11.5 ft) long, making it the largest freshwater dolphin species. dentate (Dolphins, porpoises, and all other toothed whales) are known.
Such large sizes have also been recorded in other proto-Amazonian inhabitants (i.e. fish and crocodiles) and may be due to the greater availability of resources in the proto-Amazonian ecosystem.
“16 million years ago, the Peruvian Amazon looked very different from what it looks like today,” said Dr. Aldo Benitez Palomino, a paleontologist at the University of Zurich.
“Most of the Amazon plain was covered by large lake and swamp systems called pebas.”
“This landscape included aquatic, semi-aquatic, and terrestrial ecosystems (swamps, floodplains, etc.) and spanned what is now Colombia, Ecuador, Bolivia, Peru, and Brazil.”
“When the Pebas system began to give way to what is now the Amazon about 10 million years ago, the new habitat caused Pebanista Yaclunaprey disappears, and the giant dolphin is driven to extinction. ”
“This opened up an ecological niche that is used by relatives of today's Amazon river dolphins (genus Delphinus). inia), and with the rise of new cetaceans such as modern dolphins, they were on the brink of extinction in the oceans. ”
Pebanista Yacluna was a member of platanist ideasa group of dolphins that were common in oceans around the world from 24 million to 16 million years ago.
“We discovered that size is not the only thing to note,” said Dr. Aldo Benitez Palomino, a paleontologist at the University of Zurich and the Natural History Museum of the National University of San Marcos. Told.
“With this fossil record excavated in the Amazon, we expected to find a living relative of the Amazon river dolphin, but instead we found the Amazon river dolphin's closest relative. Pebanista Yacluna It is a river dolphin from South Asia. ”
“Pebanista Yacluna and Platanista Both share a highly developed facial crown, a specialized bone structure associated with echolocation, the ability to emit high-frequency sounds and “see” by listening to their echoes, which is useful for hunting. relies heavily on this. ”
“Echolocation and biosonar are even more important for river dolphins because the waters they live in are very murky, which impedes their vision,” said Dr. Gabriel Aguirre Fernandez, a paleontologist at the University of Zurich.
“The elongated snout with many teeth suggests that: Pebanista Yacluna Like other species of river dolphins today, they eat fish. ”
large adult skull Pebanista Yacluna It was discovered in 2018 at an exposed stratigraphic level along the Rio Napo in Loreto, Peru.
“After 20 years of research in South America, we have discovered several giant dolphins in this region, but this is the first of its kind,” said Dr. Marcelo Sánchez Vilagra, a paleontologist at the University of Zurich. .
“We were particularly intrigued by its unique and deep biogeographical history.”

berry Sea buckthorn (Hippophae rhamnoides) The Canadian-grown fruit shows promising health benefits driven by its rich and diverse polyphenol profile and should be considered for further commercial expansion as a bioactive-loaded superfruit.
Sea buckthorn is a deciduous, spiny plant that grows along the coasts of northwestern Europe and in temperate regions of central Asia.
Its fruits and leaves are widely used Sea buckthorn oil has nutritional, medicinal, and functional properties and is rich in omega-3 and omega-6 fatty acids, vitamins E, B, A, and polyphenols.
The plant was introduced in Canada in the early 2000s following research into the crop's commercial potential by government agencies.
“Sea buckthorn is a unique crop with great potential for use,” said Dr. Renan Danielski. student at the University of Newfoundland.
“Popular in Asia and northwestern Europe, there is an opportunity to replicate this success in North America by leveraging the unique qualities of locally grown varieties.”
Danielski and Professor Fereydoun Shahidi of Memorial University of Newfoundland were motivated by the experimental status and limited commercialization of sea buckthorn in North America to date, and research on the antioxidant properties of Canadian cultivars. We set out to characterize the unique composition of polyphenols, a type of chemical compound.
“Understanding how our varieties compare globally will help us communicate our benefits to consumers and establish our presence in the market,” Professor Shahidi said.
The findings highlight the presence of key polyphenolic compounds in sea buckthorn pomace and seeds, each boasting potential health benefits ranging from cardiovascular protection to anti-inflammatory properties. .
Importantly, geographic factors influence the polyphenol profile of sea buckthorn berries, and researchers found that several different compounds with enhanced bioactivity are present only in sea buckthorn varieties grown in Newfoundland. is that we have identified.
Additionally, sea buckthorn extract has demonstrated promise in vitro It has anti-diabetic and anti-obesity potential, paving the way for further research into its mechanisms and potential therapeutic applications.
“This is a first step toward understanding how sea buckthorn polyphenols can modulate our physiology in beneficial ways,” Danielski said.
“Future research should focus on understanding the mechanisms behind those effects and further experiments using animal models and humans.”
“If these effects are confirmed, in vivoWe can imagine using sea buckthorn polyphenols for therapeutic and pharmacological purposes to help prevent and treat diabetes, obesity, and many other conditions. ”

Cancer is the leading cause of death in humans, accounting for almost 13% of deaths worldwide. Global Health Observatory by the World Health Organization. Biological males (or those assigned male at birth) account for 56% of cancer-related deaths, while biological females (or those assigned female at birth) account for only 44%.
The researchers showed that these differences between biological sexes are not limited to mortality rates, but are also evident in cancer development, progression, and treatment. For example, in the United States, women have a higher risk of developing breast and thyroid cancers, while men are more likely to develop prostate, colon, and stomach cancers.
Doctors also found that women tend to have colorectal cancer more often on the right side of the body, while men tend to have colorectal cancer more often on the left side of the body. Doctors want to know how biological sex affects different aspects of cancer so they can develop treatments tailored to a patient’s gender.
A team of scientists from Adityunchanagiri Pharmaceutical University in Karnataka state, India recently reviewed research on the role of biological sex in cancer. They explained that because every cell in the human body is controlled by DNA, gender can influence cancer growth at the genetic, molecular, and hormonal levels. Every patient’s biological sex changes the types of hormones and enzymes they produce, as well as the way their bodies respond to and metabolize carcinogens.
Researchers have previously found that men and women have different immune responses to cancer and chemotherapy. Women tend to have stronger immune systems that respond more strongly to cancer than men. The researchers suggested that this discrepancy may explain why fewer women die from cancer.
They also looked at data from doctors treating cancer patients and showed that similar treatments for male and female patients with the same cancer diagnosis resulted in different levels of side effects. For example, female cancer patients experience higher levels of drug-induced toxicity, infection, nausea, and vomiting during treatment than male cancer patients. They found that some anti-cancer treatments can even cause women to develop diabetes.
The researchers concluded that cancer behaves differently in male and female patients. However, despite differences in immune responses and side effects, physicians are still unable to customize immunotherapy treatments for different patients based on their biological sex. They suggested that the typical “one size fits all” approach to cancer treatment could be better tailored to specific cancer patients.
They recommended that drug companies test how new drugs affect male and female cancer patients during clinical trials before the drugs are approved. They suggested that drug companies could use this data to better estimate how much medication male and female patients should take, or for how long. They proposed that treatments tailored to each patient’s biological sex could help doctors treat patients in a more efficient manner with minimal side effects.
Cerebellum of a person suffering from kuru disease
Liberski PP (2013)
Genetic research in a very remote community in Papua New Guinea has revealed new insights into a brain disease that is spread when people eat dead relatives and has killed thousands of people over two decades.
Dotted with mountains, gorges, and fast-flowing rivers, Papua New Guinea’s Eastern Highlands province is extremely isolated from the rest of the world, and it wasn’t until the beginning of the 20th century that outsiders realized that about 1 million people lived there.
Some tribes known as the Fore practiced a form of cannibalism called “funeral feasts,” in which they consumed the bodies of their deceased relatives as part of their funeral rites. This could mean they ingested an abnormally folded protein called a prion, which can cause a fatal neurodegenerative condition called kuru associated with Creutzfeldt-Jakob disease (CJD). However, the local people believed that the Kuru phenomenon was caused by witchcraft. At least 2,700 Kuru deaths have been recorded in the eastern highlands.
Simon Mead Researchers at University College London examined the genomes of 943 people representing 68 villages and 21 language groups in the region. Although this region of Papua New Guinea covers just over 11,000 square kilometers, smaller than Jamaica, researchers say the different groups are as genetically different as the peoples of Finland and Spain, some 3,000 kilometers apart.
The study found that not everyone who attended the funeral died from the disease. Mead and his colleagues say it appears communities were beginning to develop a resistance to kuru, which led to tremors, loss of coordination, and, ultimately, death.
The study found that some of the elderly women who survived the feast had mutations in the gene encoding the prion protein, which likely conferred resistance to kuru disease.
By the 1950s, funeral feasts had become illegal, and the kuru epidemic began to subside, but visitors say that the number of women in some villages had dwindled because so many women had died from kuru. It pointed out. Mead said women and children are most susceptible to the disease, likely because they ate the brains of deceased relatives.
However, genetic evidence shows that despite fears of the disease, there was a large influx of women into Fora tribal areas, particularly in areas where the highest levels of kuru were present.
“We believe it is likely that the sexual prejudice caused by Kuru caused single men in Kuru-affected communities to look further afield for wives than usual because they were unable to find potential wives locally. “We will,” Meade said.
He said the team wants to understand what factors confer resistance to prion diseases such as CJD, which caused a severe epidemic in the UK in the 1990s.
“[Our work sets] “This is a site to detect genetic factors that may have helped the Fore people resist kuru,” Mead said. “Such resistance genes may suggest therapeutic targets.”
Ira Debson Researchers from the Garvan Institute of Medical Research in Sydney, Australia, say the study provides new insight into the “rich and unique cultural, linguistic and genomic diversity” of the Eastern Highlands region.
“This is a demonstration of how genomics can be used to look almost back in time, reading the genetic signature of past epidemics and understanding how they have shaped today’s populations. It helps.”
Lava erupts from a fissure near Grindavik, Iceland, on March 20th.

A recent eruption on the Reykjanes Peninsula in Iceland released a huge plume of sulfur dioxide (SO2) currently floating around Europe. Fortunately, no significant weather or health impacts are expected.
yes2 On March 20 in the EU, the plume moved across Ireland and the United Kingdom towards Scandinavia. Copernicus atmospheric monitoring service I said it today. It is scheduled to arrive in the Baltic states, Poland and Russia on Friday.
A person working at the Blue Lagoon Resort on the Reykjanes Peninsula, Iceland was hospitalized March 20, after being exposed to high levels of SO.2 gas. However, the plumes moving over Europe are far above the ground and do not affect the air quality below.
Say, “The plume is at a higher altitude.” Mark Purrington At Copernicus Atmospheric Monitoring Service.
Last November, a gigantic fissure, 15 kilometers long and several kilometers deep, formed under part of the Reykjanes Peninsula. Magma that had been accumulating deeper was poured into it at the fastest rate ever recorded.
On December 18, lava began erupting along part of the fissure. So far it has erupted four times, and the most recent and largest eruption began on March 17th.
“SO plume”2 All of Europe was created at an early stage [of the latest eruption]” Freistein Sigmundson At the University of Iceland in Reykjavik.
Freistein said the eruption continued as of the afternoon of March 21, although the flow slowed from its initial stages. “This eruption is different from previous ones,” he says. “It's longer than last time.”
Some volcanic eruptions release enough SO2 Although it has the potential to affect the global climate, the Icelandic eruption is not on this scale. Parrington said the plume's duration is too short to affect the weather.
Unlike the 2010 eruption of Eyjafjallajokull, which disrupted air traffic over Europe for about a week, the Reykjanes eruption is of a different type and is not expected to produce large amounts of volcanic ash.
