No one crafts blockbusters quite like James Cameron. Avatar: Fire and Ash, the highly anticipated third installment set on the enchanting moon of Pandora, is both spectacular and visually stunning. The narrative unfolds with captivating themes ranging from interspecies conflicts to deep family dynamics.

Around 15 years after the ex-Marine Jake Sully was embraced by the Na’vi, he now resides on Pandora with his partner Neytiri and their children, having played a crucial role in defeating the human invaders and merging with their Na’vi bodies.

However, they now face the heart-wrenching loss of their eldest son, Neteyam. Their arch-nemesis, Colonel Quaritch, has allied himself with an influential Na’vi tribe that inhabits a volcano and is led by the formidable Varan (as depicted above).

Shakespeare may not measure up (the dialogue is rather crude, to say the least), but the allure of this intricately designed universe is undeniable.

Prepare to be mesmerized by the breathtaking visuals and the story of Payakan, a member of the sentient whale-like species known as the Tulukun, who serves as the emotional core of the film.

Stress Management Tips

Borut Trdina/Getty Images

If you’re considering running a marathon or starting an intense exercise program this January, why not opt for a simpler goal to enhance your well-being in 2026?

Setting an objective to calm your mind may not sound ambitious, but it offers significant health benefits. A growing body of research highlights the negative impact of stress on overall health, particularly on heart health. Techniques to achieve a calm state can elevate self-reported happiness, enhance emotional regulation, and improve sleep quality research suggests.

This calmness counteracts “allostatic load,” a term used by Sula Windgassen, a health psychologist and author of the upcoming book Everything is Inside Your Body. Chronic stress contributes to wear and tear on the body, overburdening key regulatory systems like metabolic, neuroendocrine, cardiovascular, and immune functions, which can eventually lead to disease.

When discussing stress relief, you’ve likely come across traditional advice such as exercise and deep breathing techniques. While these methods are scientifically validated, there’s emerging evidence pointing to additional calming strategies beyond a digital detox or time spent in nature.

Develop a Sense of Control

Research shows that enhancing your perception of control over stressors can aid in managing them. For example, in a study, participants who completed daily questionnaires about their stressors reported that feeling in control correlated with resolving stress more effectively.

“It’s not that the stressor goes away; rather, individuals feel empowered to address it, letting it go or resolving it,” says David M. Almeida from Pennsylvania State University, a key researcher in the study.

Achieving this sense of control involves small, manageable changes. “Feeling in control doesn’t imply you have everything figured out; it means being aware of factors you can influence during stressful situations.” This might look like deciding your response, determining when to engage, or finding a resolution path.

Interestingly, your age may influence how easily you feel in control. “Longitudinal studies indicate that while older adults may feel less control over work demands and family matters, they often maintain a strong sense of control in interpersonal conflicts,” Almeida explains. “This allows individuals to focus on what truly matters.”

Practice Self-Compassion

Research increasingly supports the idea that self-kindness can mitigate stress’s adverse effects on mental health, as indicated in a 2024 study. This research assessed self-compassion levels and participants rated statements such as, “I strive to understand and be patient with parts of my personality I dislike.” Researchers later investigated how these feelings affected coping mechanisms.

Data revealed that increased self-compassion fostered healthier coping strategies, enhancing psychological well-being while reducing anxiety, depression, and stress during a six-week study period.

Using Various Self-Care Techniques for Inner Calm

These findings support earlier research, which suggests that self-compassion can buffer against the harsh realities of stress. Psychologist Kristin Neff, a pioneer in self-compassion research, emphasizes three components: self-kindness, recognizing our shared humanity, and mindfulness, which allows us to separate ourselves from painful emotions.

Self-compassion works by reducing self-criticism and rumination, according to William Van Gordon, a Chartered Psychologist and Associate Professor of Contemplative Psychology at the University of Derby. However, he advises moderation to avoid self-obsession, which can lead to heightened stress levels.

A balanced approach includes practicing compassion for both yourself and others. Van Gordon recommends active listening when someone shares their struggles with you, making eye contact, putting away your phone, and fully engaging with them (“That sounds really challenging, I’m sorry to hear that.”). Additionally, loving-kindness meditation can be beneficial; spend 10-15 minutes daily sending well wishes to others using phrases like “May you be happy” and “May you be peaceful.”

Revamp Your Self-Care Practices

Self-care strategies play a significant role in stress management, as extensively documented in the literature. Recent studies indicate that integrating diverse self-care methods into your routine yields the best results. For instance, a study published in August explored how individuals coped with stresses during the coronavirus pandemic, analyzing participants’ journaling about their anxiety levels and the coping techniques employed.

I’ve discovered that a blend of strategies such as journaling, exercise, social interaction, and cognitive reframing—like focusing on the positive aspects of not receiving a promotion—has proven most effective.

“Different combinations of tools worked for different individuals on different days,” explains Ethan Cross, an experimental psychologist from the University of Michigan involved in the research. “Those adept at managing emotions benefited from having a wide array of emotional regulation strategies.”

SEO-Optimized Title: “The Late Ordovician Mass Extinction: How It Laid the Foundation for the Evolution of Early Fish”

A significant enigma in vertebrate evolution—why numerous major fish lineages appeared suddenly in the fossil record tens of millions of years post their presumed origins—has been linked to the Late Ordovician mass extinction (LOME). This insight comes from a recent analysis conducted by paleontologists at the Okinawa Institute of Science and Technology Graduate University. The study reveals that the LOME, occurring approximately 445 to 443 million years ago, instigated a parallel endemic radiation of jawed and jawless vertebrates (gnathostomes) within isolated refugia, ultimately reshaping the early narrative of fishes and their relatives.

Most vertebrate lineages initially documented in the mid-Paleozoic emerged significantly after the Cambrian origin and Ordovician invertebrate biodiversity. This temporal gap is often attributed to inadequate sampling and lengthy ghost lineages.

However, paleontologists Kazuhei Hagiwara and Lauren Saran from the Okinawa Institute of Science and Technology Graduate University propose that the LOME may have fundamentally transformed the vertebrate ecosystem.

Utilizing a newly compiled global database of Paleozoic vertebrate occurrences, biogeography, and ecosystems, they identified that this mass extinction coincided with the extinction of stylostome conodonts (extinct marine jawless vertebrates) and the decline of early gnathostomes and pelagic invertebrates.

In the aftermath, the post-extinction ecosystems witnessed the initial definitive emergence of most major vertebrate lineages characteristic of the Paleozoic ‘Age of Fish’.

“While the ultimate cause of LOME remains unclear, clear changes before and after the event are evident through the fossil record,” stated Professor Saran.

“We have assimilated 200 years of Late Ordovician and Early Silurian paleontology and created a novel database of fossil records that will assist in reconstructing the refugia ecosystem,” Dr. Hagiwara elaborated.

“This enables us to quantify genus-level diversity from this era and illustrate how LOME directly contributed to a significant increase in gnathostome biodiversity.”

LOME transpired in two pulses during a period marked by global temperature fluctuations, alterations in ocean chemistry—including essential trace elements—sudden polar glaciation, and fluctuations in sea levels.

These transformations severely impacted marine ecosystems, creating post-extinction ‘gaps’ with reduced biodiversity that extended until the early Silurian period.

The researchers confirmed a previously suggested gap in vertebrate diversity known as the Thalimar gap.

Throughout this time, terrestrial richness remained low, and the surviving fauna consisted largely of isolated microfossils.

The recovery was gradual, with the Silurian period encompassing a 23-million-year recovery phase during which vertebrate lineages diversified intermittently.

Silurian gnathostome lineages displayed gradual diversification during an early phase when global biodiversity was notably low.

Early jawed vertebrates appear to have evolved in isolation rather than rapidly dispersing into ancient oceans.

The researchers noted that gnathostomes exhibited high levels of endemism from the outset of the Silurian period, with diversification occurring primarily in certain long-term extinction reserves.

One such refuge is southern China, where the earliest conclusive evidence of jaws is present in the fossil record.

These primitive jawed vertebrates remained geographically restricted for millions of years.

Turnover and recovery following LOME paralleled climatic fluctuations similar to those at the end of the Devonian mass extinction, including prolonged epochs of low diversity and delayed dominance of jawed fishes.

“For the first time, we discovered the entire body fossil of a jawed fish directly related to modern sharks in what is now southern China,” Dr. Hagiwara noted.

“They remained concentrated in these stable refugia for millions of years until they evolved the capability to migrate across open oceans to new ecosystems.”

“By integrating location, morphology, ecology, and biodiversity, we can finally understand how early vertebrate ecosystems restructured themselves after significant environmental disruptions,” Professor Saran added.

“This study elucidates why jaws evolved, why jawed vertebrates ultimately became widespread, and how modern marine life originated from these survivors rather than earlier forms like conodonts and trilobites.”

For more information, refer to the study published on January 9th in Scientific Progress.

The likelihood of older fathers transmitting disease-causing mutations to their offspring is greater than previously believed. Genome sequencing indicates that, in men in their early 30s, approximately 1 in 50 sperm contain harmful mutations, escalating to nearly 1 in 20 by the age of 70.

Rahele Rabari

Matthew Neville, also affiliated with the Sanger Institute, states, “This is something families should consider when making their own choices.” For instance, younger men might want to consider freezing their sperm if they anticipate delays in having children until later in life, while older men aiming to start families could explore available testing methods.

Research indicates that each individual typically carries around 70 new mutations present in most body cells that their parents do not possess, with 80% of these mutations arising in the father’s testes (excluding large-scale chromosomal abnormalities that are more frequent in the mother’s eggs). It was previously thought that the number of mutations in sperm increased steadily with age due to random mutation, but certain genetic conditions, such as achondroplasia (dwarfism), are notably more prevalent than random mutation rates would suggest.

In 2003, Anne Goriely from the University of Oxford found that this phenomenon likely stems from specific stem cells that produce sperm becoming “selfish.” This behavior causes these particular stem cells to proliferate more than usual, leading to an exponential rise in the proportion of sperm exhibiting these mutations as a man ages, rather than a steady increase. Goriely demonstrated that mutations in various genes can induce this selfish behavior in sperm stem cells, suspecting that even more factors are at play.

To date, Rahbari, Neville, and their research team have sequenced over 100,000 sperm cells sourced from 81 men of differing ages, as well as blood cells. Utilizing a unique method to sequence both strands of the DNA double helix, they overcame the high error rates in standard sequencing techniques. Thus, if a mutation is present on both strands, it is extremely unlikely to be a sequencing error.

Despite these selfish mutations comprising only a small fraction of total mutations, their impact is significant.

Ruben Arslan from the University of Witten in Germany emphasizes the discovery that these selfish mutations increase in a non-linear fashion. He suggests that, in youth, adding a year to a father’s age has a lesser negative effect compared to adding a year during older age.

Another investigation, involving Ravari and Neville, employed new sequencing methods on skin cells in the mouth, uncovering a similar trend of growth-promoting mutations that raised the ratio of specific stem cell lineages.

“These patterns of selection appear to extend beyond sperm cells,” asserts Rahbari. Although growth-promoting mutations may progress toward malignancy, they can also lead to troubles and potentially accelerate aging, she explains.

Larry Ellison is Pursuing Elon Musk for the Title of World’s Richest Person

U.S. tech mogul Larry Ellison has surpassed Elon Musk to become the wealthiest individual globally, primarily through his holdings in Oracle, the company he co-founded.

Ellison’s fortune surged after Oracle, in which he holds a 41% stake, reported stronger-than-anticipated financial performance.

In early trading, Oracle’s shares skyrocketed by over 40% to $340 each, valuing the enterprise software firm at $958 billion (£70.7 billion) and pushing Ellison’s net worth to $393 billion.

This stock surge marks the largest single-day increase in the company’s history and represents the highest one-day wealth gain ever recorded on the Bloomberg Index. Ellison and Musk currently lead ahead of Facebook founder Mark Zuckerberg and Amazon’s Jeff Bezos.

In addition to Oracle, Ellison’s wealth stems from various ventures, including Musk’s sailing team, the Indian Wells Open Tennis Tournament, and investments in Tesla, the electric vehicle manufacturer based in Hawaii, according to Bloomberg.

Musk, often at odds with different figures in business and politics, maintains a close relationship with Ellison, who is regarded as a trailblazer among South African-born tech entrepreneurs.

Ellison served on Tesla’s board from 2018 to 2022 and has invested $1 billion in Musk’s Twitter since its rebranding as X. In Walter Isaacson’s biography of Musk, it is mentioned that when the Tesla CEO asked Ellison to invest in Twitter, he replied, “What do you recommend?” The book also highlights Musk’s frequent visits to Lanai, the Hawaiian island owned by Ellison.

Ellison is known to support Donald Trump and regularly appears alongside the U.S. President, including the launch of the Stargate project, which commits $500 million to American AI infrastructure. Musk, a well-known backer of Trump’s 2024 campaign, previously had close connections with Trump before they deteriorated earlier this year.

Oracle plays a significant role in Ellison’s financial portfolio, driven by the rising demand for cloud services from AI companies needing computing capabilities, such as those utilized by ChatGPT developer OpenAI.

As reported by Bloomberg, Musk, who also leads SpaceX, first claimed the title of the richest person in the world in 2021.

He regained the title last year, but just 300 days later, it passed back to Ellison, now 81 years old.

Alternative Title: What Would Happen if Mark Zuckerberg Hadn’t Acquired Instagram and WhatsApp?

In 2012, when Facebook CEO Mark Zuckerberg cut a billion-dollar check to buy the photo sharing app Instagram, most people thought he had lost his marble.

“Billion dollars?” I was kidding John Stewart and then The Daily Show host. “For something that would ruin your photos?”

Stewart called the decision “really unfree.” His audience, and much of the world, agreed that Zuckerberg overpaid for an app that highlighted a lot of photo filters.

Two years later, Zuckerberg opened his wallet again. Facebook has agreed to buy WhatsApp for $19 billion. Many Americans had never heard of messaging apps that were popular internationally but less well-known in the US.

No one knew what would happen with these transactions. However, hindsight seems to be 20/20.

The government on Monday in a landmark antitrust trial that both acquisitions are now considered the greatest in Silicon Valley history – is the action of a lawn-protected monopoly. Zuckerberg was set up to argue that his company, renamed Meta, is merely an afterthought in the social media situation, not for these transactions.

However, this incident could lead to the division of one of the most powerful companies in technology, dealing primarily with hypotheses. Neither the government nor Zuckerberg could predict how technology would advance from Instagram’s $1 billion checks or what would happen if regulators didn’t approve the purchase. This makes Meta’s antitrust case one of the slipperyest things in the tech industry, which has long been defined by unpredictability.

“It was a very different time in Silicon Valley,” said Margaret O’Mara, a technical historian at the University of Washington, about the Facebook acquisition. “There was a vibe like, ‘Oh, wow, Facebook is a bunch of kids who really spend their luxury!” “

I happened to have a front row seat for Facebook deals, especially on Instagram. As a reporter for Wired Magazine, my office in San Francisco was next to my Instagram headquarters. We frequently visited the Kimchi Burrito location (a green slice of city) across the street near South Park Commons and ate it on a bench outside our Instagram office.

Kevin Systrom, the 6-foot-5-foot co-founder of Instagram, was 28 years old. He often roamed around the wood and iron swings of South Park Commons, calling employees and speaking about product ideas. Twitter co-founder Jack Dorsey, who identified as an arts child rather than a technician, played in the same South Park playground and meditated to a friend about the idea that eventually became his social media app.

This was a time when social apps were dismissed as play, in order to post art for lattes and to tell people what they had for breakfast. WhatsApp, which was growing rapidly internationally, was a text messaging app with no business model. And clones of these apps were abundant, including photo sharing colors, Flickr, VSCO, Message Kik, Skype, Viber, and more.

Even Facebook faced questions about whether it was a viable business. Two months after the Silicon Valley Company announced it was buying Instagram, it held one of the most Disastrous early technology revealed Since the late 1990s, it has been on the .com era.

By the time Systrom testified three months later to the California Corporation Bureau of Corporations, a condition that would close its Facebook deal, Facebook’s shares had fallen almost half the price.

However, in Silicon Valley, fortunes rise quickly. Companies move from frivolous fantasies to juggernauts in just a few years. And what might seem like a wise business move by one moment of executives can be ridiculed immediately as a mistake in the next moment. (Half of the aforementioned apps are dead, dying or have been sold as parts for a long time. Also, my favorite Kimchi Burrito locations. It’s not around anymore. )

At the time, Systrom made a positive spin on Instagram trading as the future looked increasingly tough for Facebook.

“I have been taught throughout my life that all open markets have opposites and shortcomings,” he attended the August 2012 Department of California hearing on the sixth floor of the downtown San Francisco division. “I still firmly believe in the long-term value of Facebook.”

He turns out to be right. Today, Instagram and WhatsApp are two of the most important parts of the meta business. Postings, videos and communications on the platform regularly drive global conversations for sports, news, politics and culture. The app has billions of users.

In some respects, antitrust testing is about competitive versions that may have had a history of technology. For example, what would have happened if Zuckerberg lost his Instagram bid? I’m also about to buy a photo sharing app for Twitter? What happens if WhatsApp is sold to Google? I’ll defend a little How to add a messaging app to your own portfolio?

What if other competitors create a great photo sharing app that could thrive if Facebook didn’t use Instagram to crush them? What happens if Facebook has ruined both deals or can’t keep up with competing apps and still fall behind after purchasing Instagram and WhatsApp?

These are unknown and can only be answered by those who have a time machine. Each side claims a version of what would have happened if Meta’s acquisition was not approved.

In the same Daily Show segment in 2012, senior youth correspondent Jessica Williams said that Facebook’s Instagram purchases made perfect sense.

“If you wanted a photo before Instagram that looks like it was taken in the ’60s, you’d have to invent a time machine and go back to 50 years ago,” she said. “Do you know how much it costs to build a time machine?”

“Easy billion dollars.”

Get in the Race with Mario Kart World: Nintendo’s Must-Have Title for Switch 2 Launch

hDoes OW follow just as complete and wide-ranging games as Mario Kart 8 Deluxe? Nintendo has banked in the answer: it’s getting bigger. Double the number of racers to 24. Increase the number of characters (total of 60). More weapons. And, by catching the eye the most, more exploration.

While this is not a term related to closed circuits, the three-lap formula that the series has completed over the past 30 years, in the upcoming Switch 2 flagship launch title, Mario Kart World, Nintendo has demolished the tire barrier and offers players a For the Horizon style open world. It’s not exactly a complete reinvention of the wheel, but it’s a major change in format since the series began. Considering that a physical copy of Mario Kart World is retail for £75, is that enough?

I had the opportunity to spend some time playing new games, but what immediately struck me was that it was what I would expect from the next generation Mario Kart title. It’s familiar, incredibly refined, it plays perfectly no matter what’s slaughtered, and it looks fantastic. As I ran through the course, the temptation was to slow down and incorporate all the small, quirky details.

The famous internet… Mu Moo Meadows Beef. Photo: Nintendo

Perhaps you’ll have the opportunity to do that with the free roaming element of the game. I didn’t get much opportunity to explore this. It was essentially a lobby while waiting for 24 players to join. I had two modes. First it was the Grand Prix. This is your traditional Mario Kart incident: start, 3 laps, finish. The slight tweak here is that it’s not using closed circuit courses, but sprints all over the world. The moment you are in Boo’s cinema, the next moment you’ll become a prehistoric jungle. I chose to play as a cow of Mu Moo Meadows, a breakout star known for the recent Nintendo direct internet.

As a veteran Mario Kart player (to put it gently), I found you to play as expected. Muscle Memory Takes over: You skid (maybe less agile than the MK8D to explain the wider track). You throw a shell at the enemy. Just like he was trying to use the boost, he screams in frustration when he gets hit by lightning. The level’s design is beautiful, with each track apparently packing with alternative routes and small secrets. Wideer roads mean that the game will lose some of the claustrophobic massacre and cannot escape the sense that the emphasis on weapons rather than promoting skills in the series iterations, but I can live with it. Anyway, I win my first race – I want to record it – and my cow is given a glorious crown.

My time in the game also had one race in the knockout tour mode in Nintendo’s Battle Royale Style series. Follow the course and you will encounter checkpoints on the horizon. Crossing these, the four racers below block continuous and dropouts. This continues up to the final track where the remaining four races compete on the podium. I hadn’t noticed that I would race 23 other journalists in the room with me, so I chose to choose a racing comedy choice as a Wiggler on the Pink cruiser. If I had noticed the stakes, I would have been a Wario/Monster bike, but it’s my fault to assume that it’s a race that doesn’t matter. They are all important.

Knockout Tour mode is refreshing. If, like me, you believe you can achieve a godlike position in the MK8D and run each course during your sleep, if you are used to cruising in the first place without any single bananas in your name, prepare yourself. In Knockout mode, you may start from 24th to 24th.

The solution is to embrace the massacre. I feel that weapons are more important (I lost the number of golden mushrooms, bullet bills, and star powers I experienced). Amidst all the enthusiastic confusion, I had no idea how long the race had lasted – I think I’m somewhere between 3 minutes and 3 hours. I see the checkpoint and know that I know there is only one scary, timing red shell apart. Clearing the checkpoints provided relief. It was a hurry. I finished fifth and couldn’t qualify for the final section. Aside from this shame mark, my first impression of knockout mode is that it is an exciting reinvention of form and there is a strong chance that it is trying to become my whole personality.

Possible Title: Potential Evidence of ‘Sun Stones’ Used by Ancient Societies to Combat Volcanic Winters

A stone tablet with a sun motif discovered on the Danish island of Bornholm

Antiquity Publications/John Lee, National Museum of Denmark

Hundreds of mysterious carved “sun stones” excavated in Denmark may have been ritually buried after the sun disappeared in a volcanic eruption around 2900 BC.

A total of 614 stone tablets and fragments inscribed with decorative motifs of the sun and plants have been unearthed in recent years. Basagard West Ruins Located on the island of Bornholm in Denmark. They were discovered in geological formations dating back some 4,900 years, when Neolithic people were farming the region and building enclosures surrounded by earthworks of banks and ditches.

Most of the carved sun stones were found in ditches around these enclosures, which were covered with cobblestones containing pottery shards and other items. This pottery is typical of the Late Funnel Beaker culture, which existed in the area from about 2900 to 2800 BC.

It was originally proposed that the stone carving of the sun was buried to ensure a good harvest. They say the sun was central to early Nordic agricultural culture. Rune Iversen at the University of Copenhagen, Denmark.

“But why did they store all these images at the same time?” Iversen asks. “The last thing they basically did here was deposit these sun stones and cover them with animal bone fragments and all kinds of artifacts and stuff like that. And then it went from trench to trench. You can see it being repeated. So it's some kind of action or event.”

Now he and his colleagues have found the answer. They looked at data from ice cores taken in Greenland and Antarctica and found that high concentrations of sulfate were deposited in the years following volcanic eruptions around 2900 BC.

Researchers say the relative proportions of sulfate deposition in Greenland and Antarctica suggest the eruption was somewhere close to the equator, and its effects appear to have spread over a vast area. . Ash clouds may have blocked out the sun and cooled temperatures for years.

A severe cold period around 2900 B.C. is supported by sources such as preserved wood rings from the Main River Valley in Germany and long-lived rock pine tree rings from the western United States.

This eruption would have had a devastating impact on the Neolithic peoples of northern Europe. “If we don’t have a harvest and the crop is not accepted, we won’t be able to sow anything next year,” Iversen says. “They must have felt quite punished at the time, because endless catastrophe was just going to befall them.”

He and his colleagues say burying the sculptures may have been an attempt to bring back the sun, or a celebration after the skies finally cleared.

say “that's a good explanation” jens winter johansen At the Roskilde Museum in Denmark. “There is no doubt that our staunchly agricultural society must trust the sun.”

Lars Larsson Researchers from Sweden's Lund University asked why, if climate impacts are widespread, evidence of such behavior is only found on Bornholm and not elsewhere in southern Scandinavia. Ta.

That may be because the people there had an abundance of slate, a hard stone with which to carve statues of the sun, whereas much of the rest of southern Scandinavia is mostly clay and has fewer stones suitable for carving. The body, Iversen says. “They may have carved wood or leather from other locations,” he says, but these would not normally have been preserved.

Or it may reflect cultural differences, Johansen says. “These societies are not isolated, but they are more isolated on the islands. That may be why they developed their own customs and culture.”

I have rewritten the title as: “Using Lights on Surfboards and Wetsuits as a Defense Against Shark Attacks”

A great white shark attacks a dummy seal during an experiment in which lights were used to deter shark attacks

Nathan Hart, Macquarie University

Lighting the underside of surfboards, kayaks, and wetsuits could prevent the majority of great white shark attacks on humans.

It has long been known that sharks often attack humans, mistaking their silhouettes on the water for prey such as seals. Now, researchers have conducted an experiment to see what happens when a decoy seal's silhouette is distorted by illuminating its underside to disguise its shape.

laura ryan Researchers from Macquarie University in Sydney spent nearly 500 hours towing seal-shaped decoys around Mossel Bay in South Africa's Western Cape region, where great white sharks (carcharodon carcharius) gather in large numbers to hunt.

The team tested multiple light treatments. I covered the underside of the decoy with dim, medium, and bright LED and strobe lighting, as well as horizontal and vertical strip lighting. Each time we towed with any of the light treatments, we immediately towed the control decoy seal without using any underside lighting. As an additional experiment, we conducted a paired test in which an unlit control dummy was towed 3 meters away from a lit dummy.

Unlit decoys were more likely to be attacked or chased by sharks than lit decoys. The brightest light appeared to be the most effective, with zero predator incidents when the decoy illumination was at its brightest.

Vertical strip lighting was less effective than horizontal strips, Ryan said, perhaps because it broke up the silhouette into long sections that could be identified as seals.

Strobe lighting was less effective than continuous lighting, likely because the sharks could still see the silhouette of their likely prey between flashes.

Ryan said the team expected it would be important to match the decoy's lighting with the background light and make sure it was no brighter than the surrounding underwater conditions, but that wasn't the case.

“The most important thing was that the brightness of the decoy had to be brighter than the background light,” she says. “As long as the lighting doesn't make the silhouette look black, it seems to work.”

The research team has now developed a prototype lighting array to be used as a deterrent for great white sharks. “We are now moving from research to providing protection for swimmers and surfers,” Ryan says. “We took an approach that involved understanding the sensory systems of these animals, how they see the world, and their behavior.”

Ryan cautioned that lighting deterrents have not been tested against other species known to attack humans, such as tiger sharks (Galeocerdo Cuvier) and bull sharks (Porgy whale), each with a different hunting strategy.

david booth The University of Technology Sydney conducts a number of field studies off the Sydney coastline, where sharks, including great whites, are common. Based on these findings, he says he will definitely order a counter-illuminated wetsuit when it becomes available.

“I was surprised to find that ‘destructive camouflage’ was more effective, as I thought low lighting to match the background was most effective,” he says.

“These results apply only to great white sharks, and only to this feeding mode, so it is unclear at this point how broadly applicable they are.”

A doctor explains if this fluffy mushroom truly deserves the title of ultimate superfood

If you’ve been browsing the internet recently, you’ve likely come across advertisements for Lionsman Mushroom supplements that claim to enhance health and prevent illness. But are these claims and products scientifically supported, or are they just a passing trend?


What exactly is a Lionsman mushroom?

The lion’s mane mushroom, scientifically known as Yamabushitake mushroom, is a sizable, hairy edible mushroom with a sweet taste and soft texture. It is used in gourmet cuisine and has a lengthy history in traditional medicine, attracting attention from both Western scientists and modern marketers.

There have been numerous studies on Lionsman mushrooms, with at least 410 research papers published in the last decade. However, only about a quarter of these studies have been conducted on humans, with the rest utilizing model systems like rodents or cell cultures. There have been a total of seven human clinical trials to date.

Is Yamabushitake good for your health?

Heart Health

Around one in three adults in the UK suffers from high blood pressure, and elevated cholesterol levels increase the risk of cardiovascular diseases. Lionsman extract has been studied for its potential to improve blood lipid levels, reduce oxidation, and possibly act as an anticoagulant.

Diabetes

Research suggests that Lionsman mushrooms may help control blood sugar levels, but this has only been demonstrated in rodents and cell studies, not in humans, especially those with diabetes.

Cancer Prevention

Studies have identified substances in lion’s mane mushrooms that may inhibit the growth of various cancer cells. However, more research is needed to determine if these effects translate to human consumption.

Mental Health and Cognition

Studies have shown that Lionsman extract can promote nerve cell growth, reduce oxidation and inflammation, and improve brain health. Small-scale studies have indicated potential benefits for memory and cognitive function.

Immunity and Inflammation

Lionsman compounds have been shown to have antioxidant and anti-inflammatory properties, but their effects on immunity in humans are yet to be fully understood.

Supports Gastrointestinal Health

Lionsman mushrooms have shown promise in limiting the growth of harmful bacteria and reducing the severity of gastrointestinal disorders in animal models. Human studies are still ongoing to confirm these effects.

So, can Lionsman mushroom supplements be beneficial for humans?

Most Lionsman products on the market focus on extracts, capsules, and powders, as these are easier to study than the whole mushroom. Dosage recommendations are challenging to determine due to the variability in products and the lack of conclusive data.

Are there any side effects?

Lionsman supplements are generally well-tolerated but may cause gastrointestinal upset, nausea, and skin rashes. It is important to consult with a healthcare provider before taking them, especially if you are on other medications.

Title: “How Banning my Daughter from Her iPhone Led to Positive Changes”

The signature on this essay is a pen name.

My daughter is one of the kids the U.S. Surgeon General has warned about. Our nation’s children have become “unwitting participants” in a “decades-long experiment.” Social media use poses mental health risks to young people. Young people’s “near-constant” use of social media leads to poor sleep, depression, and anxiety.

Before sixth grade, my daughter saved up her dog-walking money to buy a phone. She found a used iPhone 13 Mini on Craigslist. I set high expectations for her to get good grades, keep her room clean, take out the trash, etc. Little did I know then that the iPhone would systematically undermine her ability to accomplish these tasks and so much more.

When my daughter walked under an inflatable arch into her classroom on her first day of middle school, I took comfort in the fact that I could reach her. Like most parents, I associated my cell phone with safety, not danger. I didn’t know that social media developers were controlling her next swipe, or that her “human future” was being sold to the highest bidder, enriching the richest corporation in the history of mankind.

I learned the hard way through my daughter’s lies, manipulation, failing grades, through the “zebra stripes” scars painted on her arms.

Her school photo from sixth grade captures my daughter in her “emo” phase: feather earrings, Pink Floyd T-shirt, crooked smile. The innocence of the photo was quickly replaced by selfies: selfies with pursed lips making a peace sign; selfies with her head tilted to one side, half-face, full-body; selfies in bed. Her camera roll records her degradation: selfies of her crying, selfies with swollen eyes, selfies of her unable to leave her bedroom.

By spring semester, my daughter’s grades were slipping. I assumed she had ADHD, so I took her to a psychiatrist for a psychiatric evaluation. The afternoon sun filtered through the faux-wood blinds, casting strips of light on the black hoodie she always wore. The doctor’s questions started out predictably: Can’t concentrate in class? Can’t finish your homework? Can’t sleep? Then the interview took a scary turn. Do you feel like your life isn’t worth living? Have you ever hurt yourself? Have you ever wanted to die?

I widened my eyes at the child’s profile and answered, “Yes.” Tearing out my guts.

Doctors diagnosed her with depression and anxiety. Further testing revealed that she spent 80% of her attention on gaining the approval of her peers. No wonder she was failing math. It was a miracle she was passing her classes when only 20% of her brain was dedicated to school.

The doctor prescribed therapy and Lexapro. These helped, but he didn’t inform me of the epidemic of cell phones among middle schoolers. I later learned that my daughter is the first generation of 10-14-year-olds to actively use social media. These girls have a 151% increase in suicide rates and a 182% increase in self-harm. Her treatment assumed that her suffering was personal, not structural. In our country, we prescribe drugs to solve this societal crisis.

At the time, I was unaware of this and allowed my daughter to continue using social media. One day, I got a text message from another mother. I stared at the screen, wondering why this mother was sending me such a revealing selfie. Then I noticed a mole on the woman’s chest. It was my daughter’s.

When I showed the photo to my daughter, she gasped. She handed over her phone. I discovered she had circumvented screen limits and been on social media until the early hours of the morning. She had sent the image on Snapchat to someone named PJ. He claimed to be a 16-year-old boy, but his responses were so graphic I suspected he was older. I was horrified to learn that a cell phone is a two-way street and a platform that adults can use to abduct and traffic children.

I had a family meeting with my daughter, her father, and my mother-in-law. We agreed that my daughter would delete her social media accounts and get rid of her phone until the new school year started. After a summer of traveling, relaxing in person, and spending time with family, my daughter’s energy returned. The bags under her eyes faded, and she stopped sighing, shrugging, and rolling her eyes. She woke up and laughed. Sometimes she even wanted me to hug her.

It was hard to give my daughter’s phone back before seventh grade, but we had made a commitment. I wanted to reinforce her good behavior. I created new rules: no social media, no devices in the bedroom, turn off the phone at 8 p.m. Charge the phone on the kitchen counter. I bought an alarm clock and a sound machine. We endured a digital detox. My daughter started playing soccer. My insomnia was cured. We joined a gym and worked out together.

But within a few months, my daughter had relapsed again. Little lies, big lies. A friend’s mother sent me an email with selfies of her daughters vaping and hanging out at the mall with boys they’d never met. We had another family meeting.

“This might seem weird, but maybe my daughter doesn’t need a cell phone,” her mother-in-law said.

The words rippled through my mind. Why hadn’t I thought of that? Cell phones were destroying my daughter, but I couldn’t imagine life without them. I stayed true to the idea of the cell phone, its ideals. I had a cell phone again.

When I told her my daughter had lost her cell phone until she was in high school, she threw a tantrum. that She was the only child in her class without a cell phone, but once the tantrum subsided, she began to regain her composure. Then, within a few weeks, signs of her addictive behavior began to reappear.

I found an iPhone charger in the outlet next to her bed. She said it was to charge her AirPods. She threw herself on the ground to stop me from searching under the bed. One night, I was lying in bed thinking and it occurred to me. My daughter two Phone. I accidentally broke my Mini on a weight training machine while working out, so I bought her a new iPhone 13. I confiscated the 13, but I was able to give the Mini to her.

When I asked her the next morning, she said, “I sold it to a friend at school.” She couldn’t tell me who she sold it to or how much she paid for it.

“I’ll find it,” I said. I see you Gestures. I was distraught, but with calm confidence and a little humor, I went through backpacks and drawers, rifled through pockets, entered rooms unannounced, and tried to catch her in the act. My daughter remained calm the whole time I searched. I began to wonder if I had gone completely crazy. I bought a metal detector.

Then one night, I walked into my daughter’s room. She jumped up and pulled back the comforter. I ran to the bed and reached under the covers. The charging cord! My fingers traced its length to the plugged-in phone.

We stared at the Mini in my hands, the Snapchat app glowing beneath the cracked screen, and she looked at me, her eyes wide and filling with tears.

That night, my heart pounded against the pillow as I scrolled through her social media. Her communications were urgent and earnest. She begged one boy in particular, Damien, to get back to her. When he didn’t respond, she said she was depressed and began sexting him and sending him pictures of her breasts.

Through my sister, I found the answer in Johan Hari’s Stolen Focus. The book explores why and how our attention span is declining: “The phones we own and the programs that run on them have been purposefully designed by the smartest people in the world to capture and hold the most of our attention.” Of course. My daughter was young and vulnerable to this manipulation. She measured her self-worth within a system that was both attention-addicted and attention-starved at the same time. She had internalized an algorithm where provocative content wins. “The more outrageous something is, the more attractive it is,” Hari writes.

Our social experiment is being replicated in homes across the country. As parents, we want our kids to be safe. We want them to contact us if a shooter comes to school. But the biggest danger is At the inner Make phone calls on your cell phone, not outside.

One of the reasons our kids are addicted to their phones is because we are. My friends complain of insomnia, but they can’t imagine leaving their phones outside of their bedrooms. Addressing my kids’ phone use means addressing my own. I have to restrain myself from texting while driving. I’ve also stopped rushing to the charging station each morning to check if I’ve missed any messages.

After the seventh grade, my daughter that A child. Without a phone, she’s the kid who dribbles a soccer ball in her living room, races down the street on her skateboard, becomes an honor student and joins the track team. The kid who wags her hands while chatting with friends, braids her hair, falls asleep reading a book.

These days, we use my phone to plan outings together, listen to audiobooks, and sing along to her songs and mine (Shakira, Sade, Ice Cube, Fugees). Last weekend, we drove up the Pacific Coast Highway to visit family. As the June gloom settled over the shoreline, my daughter and I bodysurfed into the crashing waves. “Again!” she said, jumping up, enthralled by the feeling of the waves rolling under her belly.

My daughter is not the only child like this. A woman I met recently confiscated her 11-year-old son’s phone after she discovered him sexting. Since schools were required to wrap their phones in rubber bands, the sick middle-schooler has built community and focused in class. The trend is spreading fast. UK children have been learning mostly in “no-phone environments” since the Department for Education ordered it.

Individuals and and Changes to the system to check cell phone usage. I’m interested to see what happens with this change when my daughter reaches high school.

I’ll hold the phone until then.

Instagram surpasses TikTok to claim title of world’s most downloaded app

Instagram has surpassed TikTok as the most downloaded app globally, thanks to its Reels feature that helped it recover from its previous losses to its Chinese-backed competitor.

Since its launch in 2010, this photo and video-sharing platform has gained immense popularity, often associated with celebrities like the Kardashians, and giving rise to the influencer trend. However, in recent years, it has evolved into a short video platform facing tough competition from TikTok.

Instagram faced backlash in 2020 for introducing a short-form video feature that seemed to mimic TikTok. In 2023, the app was downloaded 767 million times globally, marking a 20% increase from the previous year, while TikTok’s downloads grew by 4% to 733 million.

According to market intelligence firm Sensor Tower, Instagram’s resurgence is largely attributed to the popularity of its Reels feature, along with other features like photo sharing and disappearing Stories, which mimic Snapchat.

Farhad Divecha, owner of UK-based digital marketing agency Acuracast, noted that Instagram’s quick response to the TikTok threat and its broad appeal across demographics have contributed to its success.

Mark Zuckerberg, CEO of Meta (Instagram’s parent company), acknowledged TikTok as a serious competitor and the growing competition for user attention in the digital space.

TikTok faces political challenges in the US due to concerns about Chinese ownership and data security. Lawmakers have proposed a bill that would require TikTok’s parent company, ByteDance, to sell the app within six months or face a ban.

US lawmakers and Western officials have raised concerns about TikTok’s data privacy and its potential ties to the Chinese government, allegations that TikTok has consistently denied.

Apple overtakes Samsung to claim the title of world’s top smartphone seller

Apple overtook Samsung as the world’s top smartphone seller, ending the South Korean tech company’s 12-year reign as the industry leader.

According to statistics from International Data Corporation (IDC), iPhone sold 234.6 million units in 2023, overtaking Samsung’s 226.6 million units.

IDC said Apple’s laurels with the launch of the iPhone 15 in September were due to trends such as the growing popularity of high-end devices, which now account for more than 20% of the market.

“The last time a company other than Samsung topped the smartphone market was in 2010, and in 2023, it is now Apple,” IDC said. “A sort of change in power at the top in the largest consumer electronics market was propelled by Apple’s record market share, putting it on top for the first time.”

The $2.8 trillion (£2.2 trillion) US tech company had a 20.1% market share, ahead of Samsung’s 19.4%, according to IDC. Apple has established itself as the largest smartphone maker in terms of sales and profits, but this is the first time it has led the market in terms of unit sales.

The sales data was released ahead of the launch of Samsung’s latest models on Wednesday, with the South Korean conglomerate expected to launch the Galaxy S24, S24 Plus and S24 Ultra with features powered by artificial intelligence.

Ben Wood, principal analyst at research firm CCS Insight, said the IDC data was a “mental” blow to Samsung, but he expected the competition to remain close this year.

“While I think it will remain a close race throughout 2024, there is little doubt that Apple is on a strong trajectory, and the loyalty that consumers have for Apple devices will continue to grow once they are acquired,” he said. This means that they rarely switch to something else.”

Wood said this data further emphasizes the importance of Samsung’s new product announcements on Wednesday.

“This means Samsung needs to do everything it can to not only attract new customers for its devices, but also to retain existing users.”

IDC also pointed to the increasing fragmentation of the smartphone market running on the Android operating system, citing low-end Samsung rivals such as Transsion, Xiaomi, Honor and Google.

IDC said the success of Huawei products, which were well-received in China, also contributed to Samsung’s sales decline. The data provider added that Huawei remains a competitive threat to Apple in China, the US company’s biggest market.

Global smartphone shipments fell 3.2% to 1.17 billion units in 2023, according to IDC, but the group said the industry is recovering after a downturn.

IDC added: “Growth in the second half of this year solidified the recovery expected in 2024.”

Last week, Apple was overtaken by Microsoft as the world’s most valuable company at $2.9 trillion.

Microsoft Surpasses Apple to Reclaim Title of Most Valuable Company after Two Years

Microsoft's stock closed above Apple's for the first time since 2021 on Friday, making it the world's most valuable company, as demand concerns hit the iPhone maker's stock price.

On Friday, Apple rose 0.2% and Microsoft rose 1%. This brings Microsoft's market capitalization to $2.887 trillion, an all-time high, according to LSEG data. Apple's market capitalization, calculated based on Thursday's filing data, was $2.875 trillion.

Concerns about smartphone demand have pushed Apple stock down 3% so far in 2024 after rising 48% last year. Microsoft is up about 3% since the beginning of the year after soaring 57% in 2023 on a bull run driven in part by its lead in generative artificial intelligence through its investment in ChatGPT maker OpenAI.

According to LSEG, Apple's market capitalization peaked at $3.081 trillion on December 14th.

Microsoft is incorporating OpenAI's technology into its suite of productivity software, which helped fuel a recovery in its cloud computing business in the July-September quarter. His AI leadership at the company has also created an opportunity to challenge Google's dominance in web search.

Meanwhile, Apple is grappling with sluggish demand, including for its cash cow iPhone. Demand in China, a major market, is sluggish as the Chinese economy has been slow to recover from the coronavirus pandemic and a revived Huawei is eating away at market share.

Sales of Apple's Vision Pro mixed reality headset will begin in the US on February 2nd, marking Apple's biggest product launch since the iPhone in 2007. However, UBS estimated in a report this week that Vision Pro sales are “relatively insignificant” to Apple. Earnings per share in 2024.

Since 2018, Microsoft briefly overtook Apple as the most valuable company, and most recently in 2021, when concerns about pandemic-related supply chain shortages affected the iPhone maker's stock price.

In its latest quarterly report in November, Apple gave a holiday quarter sales forecast that was lower than Wall Street's expectations due to weak demand for iPads and wearables.

Analysts on average expect Apple's December quarter sales to rise 0.7% to $117.9 billion, according to LSEG. As a result, sales will increase year-on-year for the first time in four quarters. Apple announced its financial results on February 1st.

Analysts expect Microsoft to report a 16% increase in revenue to $61.1 billion in the coming weeks due to continued growth in its cloud business.
