If we think of the universe as a continuous chain of cause and effect and time as the sequence we experience moving forward along that chain, then there is no need for concern.
Under this interpretation, the past, present, and future are all determined by unchangeable physical laws.
Even events that appear random, such as radioactive decay, are predestined and impossible to predict, but should unfold in the same way every time.
Traveling back in time to meet your younger self implies that the event has already occurred in the past.
If you don’t recall, it’s possible you were incognito or had your memory erased afterward, but we have already established how this impacted your future.
Conversely, if you were to journey to the future and encounter your future self, you would need to return to your original time and continue living your life, or else there would be no one to meet in the future.
This means that the future version of you that you meet when traveling forward in time will already have memories of your encounter as a time traveler.
Or, if each cause-and-effect interaction generates parallel universes in an infinite branching series of potential timelines, then every version of reality already exists somewhere, and your actions may not matter in the grand scheme of things.
Fortunately, time travel remains purely theoretical, and all proposed methods require exotic matter or negative energy to operate on a large scale.
This is essentially explaining one impossible concept with another. The only form of time travel we are aware of involves progressing forward at a rate of one second per second.
This article is in response to a question from Andrew Robbins emailed to us: “If time travel were possible, could we actually avoid encountering our past selves?”

Do you think you understand your pets well? What if they could actually talk to you? Veterinarian Jess French Researchers believe that humans may soon be able to communicate with animals, with potential for it to be a significant technological advancement in the near future.
In an interview with BBC Science Focus at the Cheltenham Science Festival, French explained that while humans primarily rely on visual cues, many animals have stronger senses like smell and hearing. She mentioned that artificial intelligence (AI) could be trained to understand animal communication using data and footage of animal interactions.
French envisions a future where this technology could revolutionize how we interact with our pets, potentially changing the way we take our dogs to the vet. While it may not translate a dog’s thoughts into human language, it could help pick up on signals that humans might miss, acting as a more silent version of Dr. Dolittle.
French believes that AI could help bridge the gap between animals “speaking” and humans understanding them, especially in species like whales, bats, parrots, and elephants. This technology can identify and analyze animal noises faster and more accurately than a human could.
She also mentioned that AI could enhance our ability to detect sounds outside the range of human hearing, like bat calls, and even signals in smells beyond what humans can perceive. This advancement in technology could help us better communicate with various animal species.
French highlighted that cats might already be communicating with humans in subtle ways, and AI could help in deciphering their signals. Cats, like other animals, could benefit from AI-powered communication, enabling humans to understand their behaviors and needs better.
She emphasized the importance of using this technology to learn more about animals worldwide, even if it means hearing messages we may not want to hear, such as the impact of human actions on animal populations.
About our expert: Jess French is a veterinarian, zoologist, and presenter known for her work on children’s television shows like BBC’s CBeebies. In addition to her media work, French has authored educational books for children, with her latest publication being The Animal Body Book: An Inside Guide to the World of Animal Anatomy.
TThe state of the art in AI just got a little bit further along: On Friday, Anthropic, an AI lab founded by a team of disgruntled OpenAI staffers, released the latest version of its Claude LLM. From Bloomberg:
The company announced on Thursday that a new model of the technology behind its popular chatbot, “Claude,” is twice as fast as its most powerful predecessor. In its evaluation, Anthropik said the model outperformed leading competitors such as OpenAI in several key intelligence capabilities, including coding and text-based reasoning.
Anthropik just released the previous version of Claude, 3.0, in March. This latest model is called 3.5, and it’s currently only available on the company’s mid-range model, “Sonnet.” The company says a faster, cheaper, less powerful “Haiku” version is coming soon, as well as a slower, more expensive, but most powerful “Opus.”
But even before Opus arrived, Anthropic claimed to have the best AI on the market. In a series of head-to-head comparisons posted on the company’s blog, 3.5 Sonnet outperformed OpenAI’s latest model, GPT-4o, in tasks like math quizzes, text comprehension, and undergraduate-level knowledge. It wasn’t a clean sweep, with GPT maintaining the lead in several benchmarks, but it was enough to justify the company’s claim that it’s on the cutting edge of what’s possible.
From a more qualitative perspective, AI seems to be a step forward. Anthropic states:
They have a significantly improved ability to understand nuance, humor, and complex instructions, and they excel at writing high-quality content in a natural, relatable tone.
They’re grading their own homework, and their explanation matches the changes I’ve noticed: No matter where the technical benchmarks are, I find talking to the latest version of Claude more enjoyable than any AI system I’ve used before.
But the company isn’t just selling power updates. Instead, in a way favored by smaller competitors around the world, Anthropic is focusing as much on cost as it is on features. The company claims that Claude 3.5 is not only smarter than its predecessor, but also cheaper.
Meme coins and NFTs have outlived their relevance and it is time for crypto investors to focus on RWA projects like DePin and ETFSwap (ETFS).
For the past three years, meme coins and non-fungible tokens (NFTs) have been one of the major stories in the cryptocurrency space. Thanks to all the hype surrounding these meme coins and NFTs, cryptocurrency investors are making incredible returns on their investments.
However, there is a shift in the tide that it is time to pivot away from these meme coins and NFT projects and focus on new narratives such as RWA and DePin.
Real-world assets (RWA) and decentralized physical infrastructure (DePin) are two areas that are gaining traction and could soon become the center of attention.
RWA and DePin take over meme coins and NFTs
Tokenization of assets continues to be widely discussed, with BlackRock CEO Larry Fink also Mention We see this as the “next generation of the market.” This led to more emphasis on his RWA project to bring this concept to life. Essentially, these projects utilize blockchain technology to tokenize real-world assets such as real estate, royalties, securities, contracts, ETFs, and artwork.
This will change the way investors interact with these assets by making them easier to access and trade. In terms of accessibility, asset tokenization further facilitates fractional ownership. This means that an individual can own a portion of an asset that they would not otherwise have the means to access.
By making it easier to trade these assets, previously illiquid assets will become more liquid. In general, we expect new capital inflows into all asset classes, which will increase liquidity in all asset classes. Therefore, the RWA industry is predicted to become a $1 trillion market by 2030.
On the other hand, it is worth noting that RWA projects are the tunnel through which this liquidity passes. That is why cryptocurrency investors should pay more attention to them and try to position themselves accordingly.
Similar to the RWA industry, the DePin market also boasts great potential. As the name suggests, these projects manage physical infrastructure in a decentralized manner with the help of blockchain technology and tokenization. These physical infrastructures include telecommunications, healthcare systems, power grids, and road networks.
Unlike traditional enterprises, the decentralized mode of operation of these projects helps simplify operations and reduce operating costs. On the other hand, this business model also benefits users, as they are incentivized (in tokens) to contribute to the services provided by these projects.
Given such huge potential, we expect the narrative shift from meme coins and NFTs to these RWA and DePin projects to happen sooner or later. In fact, these projects may already be the dominant story given that they have recently seen greater success than meme coins and NFT projects this cycle.
Cryptocurrency expert Michael van de Poppe correctly called it just like before the Bitcoin halving. mentioned After the halving, there will be a shift in the narrative towards RWA and the DePin project.
ETFSwap (ETFS) Pre-sale increases demand
of ETFS Wap (ETFS) Token pre-sales are already in high demand, with crypto investors turning their attention to RWA and DePin projects. ETFS is the native token of ETFSwap, a decentralized finance (DeFi) platform that enables on-chain trading of exchange-traded funds (ETFs).
This explains why investors are rushing to accumulate as many ETFSwap (ETFS) tokens as possible, as this platform is already ranked as one of the most promising RWA projects.
Meanwhile, with RWA and DePin being projected as the next big thing in the cryptocurrency space, ETFSwap (ETFS) has been instantly singled out as one of the tokens likely to move wildly in this market cycle. Experts also predict that the price of crypto tokens in particular will rise significantly, saying that it could rise in price like Shiba Inu (SHIB) in 2021.
They say this is possible because ETFSwap (ETFS) has a lot of bullish stories working in its favor. In addition to the RWA story, ETFSwap offers the following ETFs: Spot Bitcoin ETFSince its inception, it has already attracted a lot of attention in the cryptocurrency field.
Additionally, staking rewards have recently become more attractive to investors seeking passive income. ETFSwap (ETFS) stands out in this regard, as it offers a uniquely attractive yield.
Privacy concerns continue to be raised in the cryptocurrency space, with users complaining that many projects are not truly decentralized and their data is not protected. This plays out in favor of his ETFSwap, as the ETFSwap (ETFS) platform prioritizes user privacy above all else. For example, Know-Your-Customer (KYC) requirements are not mandatory on the platform, so users don’t have to worry about sharing sensitive data or having their information tracked and exposed.
Over 30 million so far ETFS Wap (ETFS) The tokens were sold in Stage 1 of the ongoing presale. This pre-sale phase is still ongoing and each token costs $0.00854. However, due to the increased demand for these tokens, we expect them to sell out before the scheduled end date.

A few weeks ago, it was quietly announced that the Future of Humanity Institute, a famous interdisciplinary research center in Oxford, no longer has a future. It closed without warning on April 16th. Initially, its website contained only a short statement that it had been closed and that research could continue elsewhere within or outside the university.
The institute, dedicated to the study of humanity’s existential risks, was founded in 2005 by Swedish-born philosopher Nick Bostrom and quickly made a name for itself beyond academia. Many high-tech billionaires praised the institute, especially in Silicon Valley, and provided financial support.
Mr. Bostrom is perhaps best known for his 2014 best-selling book. super intelligence, which warned of the existential dangers of artificial intelligence, but also became widely known for his 2003 academic paper “Are You Living in a Computer Simulation?” The paper argues that over time, humans are likely to develop the ability to create simulations that are indistinguishable from reality, and if this is the case, it has already happened and we may be the simulation. insisted.
I interviewed Bostrom more than a decade ago, and he had one of those elusive and rather abstract personalities that perhaps lends credence to simulation theory. He was pale, had a reputation for working all night, and seemed like the type of person who didn’t go out much. The Institute appears to be aware of this social shortcoming. final reporta long inscription written by Fuji Heavy Industries researcher Anders Sandberg states:
“We have not invested enough in the politics and socialization of the university to build long-term, stable relationships with faculty…When epistemology and communication practices become too disconnected, misunderstandings flourish.”

Like Sandberg, Bostrom is an advocate of transhumanism, the belief in using advanced technology to improve longevity and cognitive abilities, and is said …
“Get ready!” This immortal motto of the Scout movement will come to the mind of many readers who read the paper “Dynamics of bloodstain patterns in microgravity environment: Pilot study observations on the next frontier of forensic medicine.”
Reader Sarah Rosenbaum flagged feedback on the study’s first clearly stated purpose: “Investigating the ultimate violent criminal acts that occur outside of the global environment.”
This is the most futuristic forensic science. “It’s almost here.” The most effective approach is joint criminal investigation between the United Kingdom and the United States. The researchers are from Staffordshire University and Hull University in the UK, and the University of Louisville in Kentucky and Roswell Police in Georgia in the US.
“We hypothesize that the calculated impact angles would be more accurate if gravity were removed as a force acting on the blood droplet in flight,” they write.
They performed tests, or rather flew, aboard a parabolic flight research airplane that took off and landed at Fort Lauderdale-Hollywood International Airport. (Fort Lauderdale, like many cities in Florida, is no stranger to blood splatter. We see a steady increase in the number of violent crimes According to statistics reported by the local police department’s crime analysis department, it will occur between 2020 and 2023.)
In the experiment, “a 1 cc syringe containing a blood analogue was used to inject the liquid onto a flight path approximately 20 cm long, which was intercepted by a 16.5 cm x 16.5 cm target.” [made of] Fifty pound paper adhered to foam board backing.
The study found that droplets that hit paper at a 90-degree angle behaved as predicted by the traditional forensic blood droplet equation. But while this is a blood-stirring challenge for forensic scientists and true crime enthusiasts alike, someone needs to come up with a better equation for predicting what will happen from the other angle.
Thinking: Inside the box
Seeing sometimes leads to believing. Feeling, hearing, and reasoning are equally powerful when combined.
Shorey Croom, Hanbei Chow, and Chaz Firestone of Johns Hopkins University in Baltimore, Maryland, explain this in the magazine. PNAS How did they try to answer the question “?” “Can you tell what another person is trying to learn just by observing their movements?”
They filmed a volunteer shaking an opaque box and attempting to measure i) the number of objects hidden inside, or ii) the shape of the objects inside. He then asked others to watch the video and tried to determine “who is shaking because of the numbers and who is shaking because of the shapes.” Most observers were pretty good at recognizing who was shaking and why.
Back in 2017, Milte Plesier of Delft University in the Netherlands and Jeroen Smeets of Vrije Universiteit Amsterdam spoke to attendees of the IEEE World Haptics Conference in Fürstenfeldbruck, Germany, about a project they called “How many objects are in this box?”
Their method was simple. “We investigated how accurately participants could determine the number of wooden balls inside a box by shaking it.” They found that while they were able to perform the task accurately, they systematically underestimated the number of more spheres. The larger numbers they tested were 4 and 5. The situation with larger quantities remains theoretically unknown.
stick to fruit
Many scientists will not be able to determine whether the metal sticks to the fruit.
Generally speaking, if properly persuaded, they will. News about this can be found at “Reversibly attaching metals and graphite to hydrogels and tissues” by Wenhao Xu, Faraz Burni, and Srinivasa Raghavan of the University of Maryland.
writing in diary ACS Central Science “We have discovered that hard conductors (such as metals and graphite) can be bonded to soft aqueous materials (such as hydrogels, fruit, and animal tissue) without the use of adhesives.” The adhesion is caused by a low direct current electric field… [This] It can also be achieved underwater, where normal adhesives cannot be used.
“The experiment is very simple,” the study says, anticipating that many people would be surprised by such a simple, hitherto essentially unknown effect.
Accidental genital glow
Faraz Alam sent us the results of his research with colleagues at Imperial College London, published in the journal 2013. PLoS One “This is the paper on which I accidentally made my genitals glow in the dark.” The title is “Non-invasive monitoring of Streptococcus pyogenes vaccine efficacy using intravital optical imaging”. Those reproductive organs belonged to mice.
This spurred feedback that reminded me of a paper on humans published in 1950 by P. A. MacDonald and M. Sidney Margolese. Obstetrics and gynecology questionnaire. They called it “Luminous phenomenon of female external genitalia”.
These are both examples of how scientists perceive the wonders of biology.

Dinosaurs, in the form of birds, continue to exist today. However, traditional dinosaurs like tyrannosaurus, triceratops, and stegosaurus, are unlikely to evolve again if the climate and temperatures return to Cretaceous conditions.
While pondering this idea is entertaining, it is impossible to accurately predict future evolutionary developments. Evolution is largely influenced by chance and natural selection, which occurs in response to immediate needs rather than long-term planning.
The late paleontologist Stephen Jay Gould once contemplated rewinding the tape of life to a past era and playing it again. He theorized that each replay would result in a different world, shaped by random quirks and unpredictable paths.
One thing that becomes clear with fossil record analysis is that once a species goes extinct, it is gone forever. Trilobites, for example, have not reappeared despite similarities in today’s climate to theirs in the past.
Evolution through convergence is a powerful force, leading different species to develop similar traits when faced with similar environmental challenges. Therefore, if Earth were to undergo a Cretaceous-like climate shift, it is possible that new large reptiles may evolve, but not necessarily tyrannosaurus and triceratops.
In response to a reader’s question about the possibility of dinosaurs evolving again under different Earth conditions, this article explores the unpredictable nature of evolution and the potential for new species to emerge under changing circumstances.

From T-shirts with changing messages to carpets that can detect your position, the future of smart textiles seems to come straight out of a sci-fi novel.
Researchers now claim they have created a smart fiber that can achieve just that, without the need for a battery pack.
A team of Chinese researchers have developed textile-based electronics that utilize the human body as part of a circuit to harness electromagnetic energy from the environment.
This innovation could pave the way for a “body-bound” fiber electronics technology that functions without electronic chips or batteries and could be applied in various scenarios.
Co-author Chengyi Hou from Donghua University in Shanghai explained, “When electromagnetic energy passes through a fiber, it is converted into different forms of energy, including visible light or radio waves. Therefore, the fiber not only emits light but also produces an electrical signal when in contact with the human body.”
Hou highlighted that these radio signals are programmable by manipulating different aspects of the system, such as the fiber’s contact area with the body and its diameter.
The team stated that this method resolves a major challenge in integrating electronic systems into textiles, which is the necessity of rigid components.
Hou mentioned, “We have successfully achieved mass production of this new type of fiber electronics, which is as thin and soft as traditional fibers. The next step is to implement it.”
The team has created prototypes like a wearable cloth display with a cloth keyboard, intended for individuals with hearing impairments to aid in communication, as well as textile controllers for gaming.
Additionally, they developed a wireless tactile carpet that illuminates underfoot, providing emergency lighting at night and wirelessly transmitting signals to control household devices like lights.

Read more about the study here. The team assures that the fiber is constructed from three layers of inexpensive materials, making it durable, washable, and sweat-resistant.
An accompanying article suggests that this technology can also be utilized in robots, robotic prosthetics, and capturing haptic information to enhance human interactions and object recognition.
Dr. Luigi Occhipinti, a research director at the University of Cambridge specializing in smart electronics, biosystems, and AI, acknowledged the potential of this approach.
He stated, “By being constantly surrounded by various electromagnetic fields, we are developing innovative electronic textiles with skin sensors and unconventional electronics, powered uniquely through energy harvesting. This has the potential to unlock a new realm of self-powered wearable electronics for continuous health monitoring.”
Please try to imagine. I remember being on the bus or walking in the park and having an important task slip out of my mind. Maybe you were planning to send an email, catch up on a meeting, or have lunch with a friend. Without missing a beat, just say out loud what you forgot, and a small device strapped to your chest or placed on the bridge of your nose will send you a message, summarize a meeting, or remind a friend to go to lunch. Send invitations. No need to poke at your smartphone screen and the job is done.
This is the kind of utopian convenience that a growing wave of technology companies are trying to achieve through artificial intelligence. Generative AI chatbots such as ChatGPT exploded in popularity last year as search engines like Google, messaging apps like Slack, and social media services like Snapchat raced to integrate the technology into their systems.
AI add-ons have become commonplace across apps and software, but as the first AI-powered consumer devices launch and compete for space with smartphones, the same generation technology is poised to enter the hardware realm.
One of the first people out of the gate was eye pin California startup Humane. It’s a wearable device that’s only slightly larger than a can of Vaseline and attaches to your shirt via a magnet. You can send texts, make calls, take photos, and play music. However, there is no app support and no screen. Instead, it uses a laser to project a simple interface onto your outstretched palm. The built-in AI chatbot can be instructed through voice commands to search the web or answer queries in much the same way you’d expect from ChatGPT.
“I plan to train Ai Pin to be my personal assistant to facilitate my writing and creative work,” said the Virginia-based company, which pre-ordered the device ahead of its initial U.S. launch in April, says Tiffany Jana, a consultant with Since she travels a lot, she thinks it would be nice to have a photographer and translator to accompany her. “I don’t have all the assistants and large teams that supported me in the past. I’ve always been a tech guy and enjoy ChatGPT.”
Meanwhile, Facebook’s parent company Meta has already Smart glasses equipped with AI Partnering with Ray-Ban and Chinese companies TCL and Oppo Companies followed suit with their own AI glasses. All of these have pretty much the same functionality as Ai Pin and are sold in a way that connects to an AI chatbot that responds to voice commands.
It’s a way to curb smartphone overuse by providing the same essential functionality without addictive apps.
If all of this sounds a lot like what your smartphone’s voice assistant or your living room’s Alexa already does, that’s because that’s essentially what it does. “Using AI in new devices is still the norm today,” says David Lindlbauer, an assistant professor at the Human-Computer Interaction Institute at Carnegie Mellon University in Pennsylvania. “Everyone uses Google Suggestions, Apple Siri to navigate their phones, or smart suggestions in apps on their phones.” The difference, he says, is that these new and upcoming devices will, which aims to embed AI capabilities in a “less obtrusive and more ubiquitous way.”
Its design intent is most evident in future products pendant From US startup Rewind and software developer Tab AI Avi Shiffman. These small devices hang around your neck and passively record everything you hear and say during the day, then transcribe the most important parts so you can read them back at your convenience later. Designed to summarize. These are essentially productivity tools that bundle the kinds of generative AI capabilities found elsewhere into standalone devices.
But why would you want a device that does more than what your smartphone already has? Partly to free yourself from the less-than-welcome elements. Humane is pitching Ai Pin as a way to curb smartphone overuse by offering the same important functionality without the addictive apps that make you scroll compulsively. “An alcoholic is not dependent on the bottle, but on the contents,” says Christian Montag, chair of molecular psychology at the University of Ulm in Germany, by analogy. He says social media platforms in particular are often interested in intentionally extending screen time in order to show more ads or collect personal data. say. Experiments show that when you use your smartphone in grayscale mode, Reduce user retentionremoving the screen completely can have even more severe effects.
While this may seem counterintuitive to the tech industry’s ever-increasing appetite for new features and gadgets, it’s probably not as alien as it first seems. “Many people wear headphones all day long,” says Lindlbauer. “Therefore, it is entirely possible to move away from the temptation of scrolling through doom and move towards technology that allows us to access the digital world constantly, but unobtrusively.”
However, discussions about their broader applications are beginning to take place. For some, the future of this technology lies not in how it can be integrated into existing platforms, but in whether it can fundamentally change the way platforms are accessed. “There will be no need to use different apps for different tasks,” former Microsoft CEO Bill Gates said in an article. Blog post outlining his vision. “Simply tell your device, in everyday language, what you want to do.” Then, leave it to your device to figure out what apps, platforms, and information it needs to complete the task you set.
This is an idea that will be put into preliminary practice in the next stage. R1. Developed by Rabbit, a Californian AI startup, the R1 is a handheld device that looks a bit like a portable gaming console and operates like a powerful voice assistant. However, it is designed to interact directly with an app on your phone on your behalf, rather than simply connecting to an AI chatbot that generates passive responses to your commands (like other wearable gadgets). Masu. The idea is that R1 acts as an all-in-one interface for your device, a kind of central app that can control everything else.
“We’re not building products for new use cases. We’re developing better, more intuitive ways to address existing use cases.” said Jesse Lyu, Chief Executive Officer of Rabbit. He describes the R1 as a “digital companion” that doesn’t replace your smartphone, but makes it easier to use.
The value of that approach will become clear when R1 launches later this year. However, similar experimental devices are expected to follow. Sam Altman, CEO of OpenAI, which developed ChatGPT, is reportedly already in talks with former Apple chief designer Jony Ive to explore hardware ideas. And a group of startups and Silicon Valley powerhouses are now racing to develop the chips and processors these new devices will need to power their AI models.
Whatever form these AI devices end up taking, they will be hard to compete with the globally connected, highly capable, and intuitively controlled glass rectangles that are in most of our pockets. You’re going to have to work. However, as ubiquitous as smartphones seem, they too have an expiration date. “Smartphones have only been with us for about 15 years,” says Lindlbauer. “I don’t want to believe that smartphones are the pinnacle of technology or that we’ll ever use them the way we do now. [another] 15 years.”
Europe’s longest Hyperloop test line opening has once again sparked hopes for a future that combines maglev and vacuum tube transportation technologies.
Operators believe that this facility will demonstrate the feasibility of Hyperloop, paving the way for a high-speed tube network spanning 6,200 miles (10,000km) across the continent by 2050.
Currently, the testbed at the European Hyperloop Center in Veendam is a 420-meter-long bifurcated white pipe running alongside a track and road, not yet transporting people in the Netherlands.
The test pipe, constructed from 34 connected 2.5-meter-wide prefabricated steel cylinders, partially funded by the EU, falls short of the envisioned two-mile track for 2020 due to speed limitations. The goal is to achieve the required 620 mph (1,000 km/h) in the future.

The Vandeem pipe’s fork will be instrumental in testing “lane switching” during high-speed vehicle course changes, with initial tests conducted by Hard Hyperloop in the Netherlands.
The center’s director, Sacha Lam, hailed this development as a pivotal moment, envisioning a pan-European network with infrastructure branching to various destinations like Paris and Berlin.
The concept of the Hyperloop was introduced by Elon Musk in 2013, proposing a line between San Francisco and Los Angeles. This innovative transportation method could revolutionize travel speed and efficiency.
Despite past setbacks, such as Hyperloop One’s bankruptcy, proponents like Sacha Lam see a bright future where a European Hyperloop network could become a reality within decades, offering a cleaner, quieter, and faster mode of transportation.

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.”

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.

HHydrogen is a fascinating substance, being the lightest element. When it reacts with oxygen, only water is produced and an abundance of energy is released. This invisible gas looks like the clean fuel of the future. Some of the world's top automakers hope it will usurp batteries as the technology of choice for zero-emissions driving.
In our EV myth-busting series, we've looked at a range of concerns, from car fires to battery mining, range anxiety to cost concerns and carbon emissions. Many critics of electric cars argue that gasoline and diesel engines should not be abandoned. This article asks whether hydrogen offers a third way and has the potential to overtake batteries.
Claim
Many of the strongest arguments for the role of hydrogen in the auto industry are coming from CEOs at the heart of the industry. Japan's Toyota is the most vocal promoter of hydrogen, with Chairman Akio Toyoda saying last month that he expects the share of battery cars to peak at 30%, with hydrogen and internal combustion engines making up the rest. Toyota's Mirai is one of the only widely available hydrogen-powered vehicles, along with Hyundai's Nexo SUV.
“Hydrogen is the missing piece of the jigsaw when it comes to emission-free mobility,” Oliver Zipse, president of German automaker BMW, said last year. BMW may be investing heavily in battery technology, but the company is testing the BMW iX5 hydrogen fuel cell vehicle despite using Toyota's fuel cells. “One technology alone is not enough to enable climate-neutral mobility around the world,” said Zipse.
science
Hydrogen is the most abundant element in the universe, but that doesn't mean it's easily available on Earth. Most of today's pure hydrogen is made by decomposing carbon from methane, which releases carbon. Zero-emission “green hydrogen” is produced through electrolysis. In other words, it uses clean electricity to split water into hydrogen and oxygen.
To use hydrogen as a fuel, it can be burned or used in fuel cells. Hydrogen reacts with oxygen in the air in the presence of a catalyst (often made of expensive platinum). This strips the electrons flowing through the electrical circuit and charges the battery, which can power the electric motor.
According to Jean-Michel Billig, chief technology officer for hydrogen fuel cell vehicle development at Stellantis, hydrogen enables refueling in four minutes, higher payload and longer range. (The Mirai can travel 400 miles on a full tank.) Stellantis, which began producing hydrogen vans in France and Poland last month, is targeting companies that want to use their vehicles all the time but don't want the downtime required to charge them. .
“They need to be on the streets,” Billig said. “If there are no taxis running, you will be losing money.”
Stellantis believes it can lower sticker prices. Billig said that although the company manufactures both, he expects “by the end of this decade, hydrogen mobility and BEVs will be on par from a cost perspective.”
Many energy experts do not share hydrogen carmakers' enthusiasm. Tesla CEO Elon Musk has described this technology as “sold by idiots.” Why use green electricity to make hydrogen when you can use the same electricity to power your car?
All energy conversion involves wasted heat. This means that hydrogen fuel necessarily provides less energy to the vehicle. (These losses are even greater when hydrogen is directly combusted or used to make electronic fuels that replace gasoline and diesel in noisy, hot internal combustion engines.)
David Sebon, professor of mechanical engineering at the University of Cambridge, said: “With green hydrogen, it would take around three times more electricity to produce the hydrogen to power a car than just to charge the battery. “It will be.”
This may be a slight improvement, but not enough to cause problems with the battery. “It's hard to do anything much better than this,” Sebon said.
Michael Liebreich, chairman of Liebreich Associates and founder of analyst firm Bloomberg New Energy Finance, is an influential “Hydrogen ladder” – A league table ranking the use of hydrogen in terms of whether there are cheaper, easier or more likely alternatives. He placed automotive hydrogen on the “doom row”, with little opportunity even in niche markets.
Can hydrogen overtake car batteries? “The answer is no,” Liebreich said without hesitation. He added that carmakers betting on a large share of hydrogen would be “completely wrong” and set for costly disappointments.
The main problem with hydrogen cars is not the fuel cells, but actually delivering clean hydrogen where it is needed. This gas is highly flammable, with all the attendant safety concerns, so it must be stored under pressure and easily leaks. It also contains less energy per unit volume than fossil fuels, so unless you use electrolyzers on site, you will need many times more tankers.
The United States and Europe are beginning to invest in hydrogen supplies with heavy government subsidies. But so far, it has been a chicken-and-egg problem. Buyers don't want hydrogen cars because they can't fill them up, and since there are no cars, there are no filling stations. According to the European Hydrogen Observatory, there are 178 hydrogen filling stations in Europe, half of them in Germany. In the UK, he compares nine hydrogen stations to 8,300 petrol stations or his 31,000 public charging locations (not including household plugs).
Are there any precautions?
So why does the International Energy Agency think hydrogen will account for 16% of road transport in 2050 on the path to net zero? The answer lies primarily in heavy vehicles such as buses and trucks .
Liebreich said he is so convinced that batteries will continue to dominate the energy supply for heavy-duty vehicles that he co-founded a truck charging company. “HGVs may contain hydrogen, but it will be in the minority,” he said.
Speaking to Autocar in October, even Toyota admitted that the use of hydrogen in cars has so far been “unsuccessful” primarily due to fuel supply shortages. said Hiroki Nakajima, technical director. Trucks and coaches have high hopes for the technology, and the company is also prototyping a hydrogen version of its Hilux pickup truck.

verdict
As government enthusiasm waxes and wanes, the economics of hydrogen will change as well. Other changes may occur. As technology improves (within limits), gas may become more attractive, and prospectors may be able to find cheap “white hydrogen” drilled out of the ground.
However, when it comes to cars, it seems like the deal has already been settled. Batteries are already the second choice after gasoline for almost all manufacturers. According to the Motor Vehicle Manufacturers and Trade Association, fewer than 300 hydrogen cars will be sold in the UK over 20 years, compared to 1 million electric cars.
The battery advantage is likely to grow even further as research and infrastructure dollars address issues of range and charging time. Compared to that flood of investment, hydrogen is a tiny fraction.
Proponents of hydrogen now face the question of whether they can build a profitable business in transporting long-distance, heavy goods by road. They need answers soon about where they will get enough green, cheap hydrogen and whether that gas is better used elsewhere.
WBack in 2000, the Investigatory Powers Regulation Bill was introduced by the Blair government, which enshrined formidable surveillance powers into law. Long before Edward Snowden revealed his secrets, it was clear to those paying attention that the British deep state was gearing up for the digital age. The powers implicit in this bill were so broad that some expected it to pass the House with a bang.
However, the majority of MPs surveyed didn’t seem interested in the bill. Only a handful of his 659 elected members seemed concerned at all about what was being proposed. Most of the work to improve bills as they pass through Parliament is done by a small number of members of the House of Lords, some of them hereditary members, rather than elected members. It was eventually revised and became law (nicknamed Ripa) in July 2000.
In 2014, the government commissioned David Anderson QC (now KC) to investigate its operation and recommended that new legislation be enacted to clarify the questions Ripa raises. Home Secretary Theresa May introduced a new investigatory powers bill in the House of Commons in 2015, which was scrutinized by a joint committee of the Lords and the House of Commons. This bill became the Investigatory Powers Act (or “Peep Charter”) in November 2016. The following month, the European Court of Justice ruled that the general retention of information legalized by the law was unlawful.
In 2022, the Home Office conducted a review of how the act worked. It concluded that the law had “largely achieved its objectives” but that further significant reforms were needed “to take into account advances in technology and the evolving demands of protecting national security and tackling serious crime.” Spies needed legislative support and more formally sanctioned wiggle room.
The Investigatory Powers (Amendment) Bill is currently before the Lords of Westminster. “The world has changed,” the blurb says. “Technology is advancing rapidly and the types of threats the UK faces continue to evolve.” It aims to enable security and intelligence agencies to respond to a range of evolving threats. And of course, this is global Britain, so “world-leading safeguards within the IPA will be maintained and strengthened”.
Upon closer inspection, the bill should give security services more latitude in building and leveraging so-called “mass datasets of personal information” and collecting and using CCTV footage and facial images. The bill also allows for the “collection and processing of Internet connection records” for generalized mass surveillance.
The bill will force technology companies, including overseas bases, to inform the UK Government of any plans that may require improving security or privacy measures on their platform before these changes take effect. For instance, Apple views this as an “unprecedented overreach by the government” that could see the UK “covertly veto new user protections globally and prevent us from delivering them to our customers”.
A hat-trick, at least for global Britain.

There are TikTok hashtags with millions of followers, endless columns about celebrity waistlines, and a flurry of media coverage when test results come out. It is rare for a new drug to receive so much attention. However, it is even more rare for approved drugs to cause safe and rapid weight loss with minimal effort.
A year ago, most people had never heard of semaglutide. Semaglutide is a drug developed about 10 years ago under the brand name Ozempic to treat type 2 diabetes. It was later approved as a weight loss aid in the US in 2021 under the name Wegovy. With this drug, people can lose a whopping 15% of their body weight.
The impact of this new class of medicines could be unprecedented and could end the world's growing obesity epidemic. “I don’t think it’s fully sunk in yet,” he says. Jonathan Campbell At Duke University in North Carolina, he studies how these drugs affect the body.
First, Wegovy was just the beginning. The next generation of these drugs is in development and will be cheaper, easier to use, and, importantly, even more powerful. Additionally, new evidence suggests that Wegovy and its similar products are more effective when given at a younger age, so doctors are considering their use in teenagers and young children. This increases the possibility of switching from obesity treatment to prevention. “Over the past 40 years, we have seen the obesity landscape change dramatically,” Campbell says. “Now we may be at a tipping point where that goes backwards.”

On the day the world ended, Renku Sketlish, CEO and founder of Fantail Social Network, sat under a redwood forest in a designated natural beauty spot at dawn and tried to inhale through his navel.
The snow-capped peaks of distant mountains capture the imagination with their curves and crevasses. The nearby trees were maroon for fawns and gray-green for sage. The sequoia's trunk was solid, with cords and twisted vine-like patterns, and its surface was softened by moss and grass. Small insects buzzed around in the dense mass.
“There is no way to really know what's going to happen next,” the instructor said.
Well, it was all a shit show. There was no way to know. Something might happen in the next moment. There might be an opportunity, someone might grab a new idea, or a competitor might try to steal your property. It's also possible that company-stealer Ellen Bywater has Medlar's all-seeing eye in his direction, and her gleaming, elegant hardware is an aspirational alternative to the workaday fantail. Medlar Torc is her new thing, and all her communication needs are handled by this stylish device. She now always seems to be one step ahead of him, seducing his key demographic like she stole Medlar.

We always forget the truth about power. Every generation has learned that it is not the individual, not the office, but power that ultimately irreparably corrupts and distorts even the best characters with the best intentions. I need to be reminded of this again.
I thought about this a lot when writing the novel. future. I've always been interested in writing about power. Most of my books are about how power systems change us and how we change power systems. future It is by far the most powerful individuals on the planet today: those of us who operate, for the most part, without tax or government constraints, without term limits, and who are the “citizens” of their online spheres. We're talking about tech billionaires who operate without having to answer to anything. How did they get there? Why is it so difficult to live outside the infrastructure they have created? And how has it turned them into such centers of power?
There was one book that made a big difference in my way of thinking.
In 1974, Robert Caro published a unique and extraordinary book. power broker. This lifted the lid on Robert Moses, the great builder of New York City's infrastructure (roads, bridges, parks, tunnels, public buildings). Those who knew him personally knew him to be a tyrant and a bully. His plans had long since ceased to make sense except as a means to gain more power.
power broker The book is 1100 pages long, but it is so engaging and engaging that I wish it had a few hundred more pages. This work shows that Moses started out as an idealist. At the start of his career, this is a man who aspired to build diaper changing stations in New York parks, but was so changed by his powers that he ended up suppressing major infrastructure projects became. He cannot be in charge of them. At the back of my copy are questions most readers probably asked themselves as they read on. What did it take? ” Behind that lies another question. How can we detect this early and take immediate action?
Humans in the future may choose to live extraterrestrial lives on the Moon, Mars, or even Venus. However, the question arises of how they will continue to reproduce and survive once they get there. What happens to their reproductive systems? Is it possible for babies to be born in space?
To find answers to these questions, we interviewed space gynecologist Dr. Varsha Jain. She has published a paper from the University of Edinburgh on women and reproductive health in space.
What Does It Mean to Be a Space Gynecologist?
A space gynecologist is someone who is interested in space medicine and is also a gynecologist. Dr. Varsha Jain, the first person to be awarded this title, began this work about 10 years ago. She focuses on women’s health related to the health of astronauts.
We’ve had some huge breakthroughs for women in space, and that history starts with some pretty amazing myths. Can you tell us a few things about them?
Dr. Jain discussed how early myths caused a delay between the first woman to fly in space (Valentina Tereshkova) and the first American woman to fly in space almost 20 years later (Sally Ride). There was concern over issues like “retrograde menstruation” and how many menstrual products astronauts would need.
Have Attitudes Towards Women in Space Changed?
Dr. Jain noted a significant improvement in attitudes and how NASA supports open access and evidence-based information about female astronauts’ health. They even support the idea of female astronauts freezing their eggs before going into space.
What Happens to Our Reproductive System in Space?
Dr. Jain explained that astronauts’ hormonal cycles do not seem to change in space. Menstruation still occurs, and women can ovulate, potentially leading to fertilization and pregnancy. Although these things may be possible, the focus is currently more on keeping astronauts healthy than finding out if babies can be born in space.
What Do We Know About the Risks to Women’s Bodies and Pregnancy in Space?
Dr. Jain pointed out that radiation in space poses a risk to a developing fetus and that the effects of space travel on the body, including weightlessness and changes in blood volume, could impact pregnancy. Many unknowns still exist around this topic.
Given That There Are Still Many Gaps in Our Knowledge, How Realistic Are Plans to Start an Extraterrestrial Human Colony?
Dr. Jain believes that, while there’s much to learn and research, human curiosity will likely lead to humans colonizing other planets and moons in the future. However, she stressed that extensive research is needed to ensure the safety of such endeavors.
What Impact Could Space Travel Have on What We Know and Don’t Know?
Dr. Jain described the potential for space travel to provide answers about reproductive health and fertility. She believes that space agencies may investigate these questions in the future, potentially leading to new discoveries.
Are Citizens, Scientists, and Nations Racing to Have a Baby in Space?
Although the concept of reproductive health in space may seem fascinating, Dr. Jain emphasized the need for more funding and research in this area. She believes that reproductive health is often underfunded on Earth and that more focus and funding are necessary to understand the effects of the space environment on the human body.

In the relatively short period of space exploration history, the moon has experienced significant changes as a result of human activity. From the historical significance of our first footprints to the damage caused by spacecraft crashes, our impact on the moon is evident and nearly preserved within the moon’s regolith.
For the past 1.1 billion years, the Moon has been in the Copernican Era, the current epoch. Now, there are calls for a new lunar era to be formally defined: the lunar Anthropocene. This proposed era started in 1959 with Russia’s first-ever landing of the Luna 2 spacecraft on the moon. With upcoming missions like NASA’s Artemis and Lunar Gateway, further changes are expected.
Dr. Justin Holcomb, a space archaeologist, and researcher at the University of Kansas, USA, was interviewed.
What markers suggest that a new era has begun on the Moon?
Unlike the Earth’s Anthropocene, the moon provides a unique setting for human activity to be recorded due to its limited systems and ability to preserve the entirety of human history. The relatively slow impact of meteorite collisions has historically been the primary cause of change on the Moon, contrasting with the addition of the human variable now present on the lunar surface.
What’s the biggest impact we’ve had there?
When humans land on the Moon, they significantly impact the surface. However, accidental impacts, such as spacecraft crashes, pose a significant risk and have occurred multiple times since 2019. These accidents jeopardize planned areas of operation and can potentially erase important historical sites on the Moon.
What else do we have left there?
Various artifacts and items have been left on the Moon, including personal items, scientific equipment, and the national emblem on India’s rover. It’s argued that the space debris on the Moon should be considered as space heritage rather than just waste, and thus, it needs to be protected as such.
How are human activities changing the Moon’s geological processes, and to what extent can humans disrupt the balance of the Moon’s system?
The impact of human activities on the Moon’s geological processes, such as the movement of lunar regolith and potential contamination of ice due to rocket fuel, presents concerns for the future. These impacts could have far-reaching consequences and affect the balance of the Moon’s system.
How will the Moon change further for future space missions after 2024?
With a focus on mining and the potential for private companies to be involved in future space missions, the Moon is expected to experience significant changes in the coming years. The increase in planned lunar missions indicates a new phase in the relationship between humans and the moon. With the rise of private space companies, the landscape of space exploration has shifted.

Researchers are developing a hydrogen-based vehicle fuel system that uses catalytically converted liquids and has zero greenhouse gas emissions. Although this method is still being researched, it faces challenges such as catalyst durability and the environmental friendliness of hydrogen production, highlighting the need for political support for renewable energy.
Researchers at Sweden’s Lund University have developed an innovative vehicle fuel system that minimizes greenhouse gas emissions and operates in a circular manner. The system utilizes a unique liquid that, when combined with a solid catalyst, turns into hydrogen fuel for cars. After use, the used fluid is removed from the vehicle’s tank and refilled with hydrogen, making it available for reuse. This process forms a closed-loop system that significantly reduces environmental impact.
In two research papers, Lund researchers have demonstrated that the method works, and although it is still basic research, it has the potential to become an efficient energy storage system in the future.
“Our catalyst is one of the most efficient, at least according to published studies,” says one of the authors, Ola Wendt, professor in the Department of Chemistry at Lund University.
Addressing climate impacts and exploring hydrogen gas
Reducing our climate impact requires finding alternative ways to produce, store, and convert energy to reduce carbon emissions from fossil fuels. One method involves the hot topic of hydrogen gas, which many see as the future solution for energy storage. Nature stores energy through chemical bonds, and hydrogen contains the highest energy density relative to its weight.
“But gas can be difficult to handle, so we are looking at hydrogen-filled liquid fuels that can be delivered at the pump, in much the same way as is done at gas stations today.” Ola Wendt he says.
This concept is known as LOHC (Liquid Organic Hydrogen Carrier) and is not new in itself. The challenge is to find the most efficient catalyst possible to extract hydrogen from the liquid.
The system is designed to operate using a liquid “filled” with hydrogen. The liquid is pumped through a solid catalyst to extract the hydrogen. This can be used in fuel cells that convert chemical fuels into electricity, and the “spent” liquid is taken to a separate tank. Only water is expelled.
Refueling and large-scale production
Used fluid can be emptied at a filling station before being refilled with new fill fluid. This would likely mean large-scale production of materials comparable to today’s oil refineries.
“We converted more than 99 percent of the hydrogen gas present in the liquid,” says Ola Wendt.
Researchers are also calculating whether the fuel could be used in larger vehicles such as buses, trucks and airplanes.
“With the larger tanks they have, they might be able to cover about the same distance as a diesel tank. They would also convert about 50% more energy than compressed hydrogen,” says Ola. Wendt says.
Components and challenges
The liquids used are isopropanol (a common ingredient in screen wash) and 4-methylpiperidine.
Does this seem a little too good to be true? Yes, many challenges remain, at least for now. One is that catalysts have a fairly limited lifetime. Another reason is that iridium, which is the basis of the catalyst, is a precious metal.
“However, we estimate that each car requires about 2 grams of iridium. ,” says Ola Wendt.
This is a technical solution based on basic research. Ola Wendt believes that if the decision is made to develop a finished product, the concept could be completed within 10 years if it is economically viable and there is interest from society. I am.
Another issue is how hydrogen is produced. Today, most manufacturing is not climate friendly. Next, hydrogen needs to be stored and transported in an effective way, which is not so easy today. Compressed hydrogen refueling also has risks. Lund researchers hope to solve this problem in their own way.
“Ninety-eight percent of all hydrogen today is fossil-based, produced from natural gas. The byproduct is carbon dioxide. From an environmental perspective, the concept of producing hydrogen for steel, batteries, and fuels is “It makes no sense if it’s done using natural gas,” says Ola Wendt, but explains that a lot of research is being done on how to “produce hydrogen in an environmentally friendly way.” To do. “Hydrogen” can be produced by splitting water into hydrogen and oxygen with the help of renewable energy.
At the same time, Ola Wendt believes that political decisions are needed for renewable and climate-friendly alternatives to gain a proper foothold.
“It needs to be cheaper, and that will require a political decision. Renewable energy has the potential to compete with just digging it out of the ground, where transportation is almost the only cost, as is the case with fossil fuels. There is no gender,” he concludes.

Researchers at the University of Nottingham have discovered an important role for diligent proteins in plant roots, regulating water and nutrient uptake by controlling the endothelial lignin barrier. This discovery has important implications for the development of drought-tolerant crops that require fewer resources. The researchers also emphasized the importance of this discovery in adapting agriculture to changing climate conditions and ensuring future food security.
Researchers have identified the role of proteins that seal plant roots and control the uptake of nutrients and water from the soil. This breakthrough could lead to the development of climate-resilient crops that require less water and less chemical fertilizers.
researchers University of Nottingham We have identified a new component of the plant root lignin barrier and a specific function of diligent proteins (DPs) located in the root endodermis that control water and nutrient uptake. Their research results are science.
Root function and endothelium
Plant roots function by absorbing mineral nutrients and water from the soil and controlling the proper balance within the plant. This control is carried out by a specialized layer of root tissue called the endothelium.
The endodermis contains a barrier to solute and water movement made of lignin, the same substance found in wood. This impermeable barrier blocks uncontrolled movement of substances into the roots by forming a tight seal between cells. This seal ensures that the only route for nutrients and water to enter the roots is through the endothelial cells. This gives the cells complete control over what enters and exits the plant through the roots.
Role of Diligent Protein
This study identified a new component of the lignin deposition machinery, focusing on the function of diligent proteins (DPs) present in the root endothelium. These proteins act in conjunction with other described root control components to direct and organize the correct deposition of lignin into the endothelium, ensuring that the plant receives an optimal balance of nutrients from the soil. will do so.
Dr Gabriel Castrillo, from the School of Biological Sciences at the University of Nottingham, one of the study’s leaders, said: They can be future-proofed to secure future food supplies. This study shows how plant roots regulate water and nutrient uptake through DP-regulated lignin deposition. Without these proteins, proper root sealing is not completed and the nutritional balance within the plant is compromised. This knowledge can be used to engineer plants to grow with less water and chemical fertilizers. ”

South African aerospace startup Cloudline is aiming to lead the global frontier of carbon-free autonomous flight and has secured $6 million in funding. The funding comes from supporters including philanthropic venture Schmidt Futures, founded by former Google CEOs Eric Schmidt and Wendy Schmidt. Other supporters include Pan-African Funds such as Raba Partnership, Verod-Kepple Africa Ventures, and 4Di, as well as other venture companies.
The founder and CEO of Cloudline, Spencer Horne, originally intended to build a transportation system that would use lighter-than-air unmanned aerial vehicles to deliver large payloads and connect isolated communities to global supply chains. His interest in the Moonshot project stems from his childhood fascination with trains and passion for transportation technology, particularly aviation.
After spending time at McKinsey and establishing a professional network, Horne returned to Africa to contribute to the field of aeronautics. In 2016, he founded Cloudline at the intersection of technology, transportation, and community impact. The company has since developed an autonomous airship that provides a cost-effective alternative to drones, helicopters, and satellites for real-time data collection in hard-to-reach locations.
Cloudline’s airships can travel more than 400 km with a full payload of 40 kg and fly for up to 10 hours using helium gas and solar power, producing zero emissions and significantly reducing operating costs. The company also combines various sensor data in a single flight, offering solutions for utilities, conservation efforts, and more.
The company has seen a significant increase in revenue and is expected to experience substantial growth in the coming years after signing multi-million dollar enterprise deals. The first-mover advantage and integration of software and hardware give Cloudline a strong market position, particularly in development for the African continent’s specific needs.
International astronauts will join U.S. astronauts on the moon by the end of this decade under an agreement announced Wednesday by NASA and the White House.
The news came as Vice President Kamala Harris convened a meeting of the National Space Council in Washington, the third such meeting under the Biden administration.
There was no word on who the international moonwalker would be or what country he would represent. A NASA spokesperson later said the crew will be assigned to a location close to the lunar landing mission, and no commitments to other countries have been made yet.
NASA has been sending international astronauts on space trips for decades. Canadian Jeremy Hansen About a year from now, it will fly around the moon with three American astronauts.
Another crew member will actually land. This will be the first landing by astronauts on the moon in more than half a century. According to , it is unlikely to happen before 2027. U.S. Government Accountability Office.
All 12 moon walkers on NASA’s Apollo program in the 1960s and 1970s were U.S. citizens. The space agency’s new moon exploration program is named Artemis, after the mythical twin sister of Apollo.
Including international partners is “not only deeply appreciated, but also urgently needed in today’s world,” Hansen told the board.
NASA has long emphasized the need for global cooperation in space, and in 2020 established the Artemis Accords with the U.S. Department of State to promote responsible behavior not only on the moon but everywhere in space. Representatives from all 33 countries that have signed the agreement so far are expected to attend the Space Council meeting in Washington.
“We know from experience that cooperation in space pays off,” Secretary of State Antony Blinken said, citing the Webb Space Telescope, an effort between the United States, Europe and Canada, as an example.
Notably absent from the Artemis Accords are Russia and China, the only countries other than the United States that have sent their citizens into orbit. Russia is her NASA partner on the International Space Station, along with Europe, Japan and Canada. Even in the early 1990s, the Russian and U.S. space agencies collaborated on a shuttle program to launch each other’s astronauts to Russia’s former orbiting Mir base.
At Wednesday’s meeting, Harris also announced new policies to ensure the safe use of space as more private companies and nations take to the skies. The problems the United States is trying to solve include the climate crisis and the growing amount of space junk on Earth. Russia’s anti-satellite missile tests in 2021 added more than 1,500 pieces of potentially dangerous orbital debris, prompting Blinken to join other meetings and urge all countries to conduct such destructive tests. I asked them to cancel it.

Breaking down the pitch deck: Metafuels’ $8 million climate technology seed deck
Metafuel has raised $8 million in seed funding to support its plan to reduce aircraft emissions. However, resident pitch expert Hadje Jan Kamps quickly realized that there were some areas that could be improved. The competition slides are missing, the team his slides are a bit lacking in vibrancy, and the lack of clear questions and use of the funding slides.
Still, Metafuels can paint a picture of a rapidly growing market and how it is positioning itself as a key player within it.

A quick guide to ethical and responsible AI governance

“A strong ethical and risk management framework is essential to navigate the complex landscape of AI applications,” said Phani Dasari, Chief Information Security Officer, Hinduja Global Solutions.
Dasari thoroughly implements key components of AI governance, including policies, procedures, and the processes themselves, helping businesses avoid the risks and benefits of using AI.
It was shocking for AI, as it moved from niche to mainstream technology faster than ever before. But 2024 will be the year when this hype really becomes reality as people consider the capabilities and limitations of AI as a whole. Here are some ways we think that could happen.
OpenAI becomes a product company
After a management shake-up in November, OpenAI will be a different company — it may not look like it on the outside, but the trickle-down effect of Sam Altman taking more full charge will make all the difference. You can feel it on the level. And one of the ways we expect that to manifest is through the idea of “shipping.” You can see that in the GPT store. Originally he was scheduled for release in December, but was understandably delayed due to executive turmoil. “AI app store” will continue to be strongly promoted as a platform to get AI toys and tools. Don’t worry about Hugging Face or any other open source model. They have a great model called Apple and they follow it all the way to the bank. Expect to see more similar moves from OpenAI in 2024, as the prudence and academic reserve exhibited by previous boards gives way to unseemly greed for markets and customers. Other big companies working on AI will likely follow this trend (e.g. we expect Gemini/Bard to get into a ton of Google products), but I suspect it will be more pronounced in this case.
Agents, generated videos, and generated music graduate from quaint to experimental
Some niche applications of AI models, such as agent-based models and generative multimedia, will grow beyond “meh” status by 2024. If AI is going to help you do more than summarize things or create lists, it will need access to spreadsheets, ticket-buying interfaces, transit apps, and more. In 2023, several attempts were made with this “agent” approach, but none really caught on. I don’t expect anything to really take off in 2024 either, but I think agent-based models will look a little more convincing than they did last year. We’ll also see some clutch use cases that are notorious for tedious processes such as submission. Insurance claims. Video and audio will also find a niche where their shortcomings are less obvious. In the hands of skilled creators, the lack of photorealism will not be an issue and AI video will be used in fun and interesting ways. Similarly, generative music models are likely to be adopted by some major productions, such as games, where professional musicians can also leverage the tools to create endless soundtracks.
The limitations of monolithic LLM become clearer
So far, there’s been a lot of optimism about the capabilities of large-scale language models, and they’ve actually proven to be better than anyone expected, and can be used to create more computing power. As more are added, its capabilities further increase accordingly. But 2024 will be the year that something will be given. There is a lot of research going on at the forefront of this field, so it is impossible to predict exactly where this will happen. The seemingly magical “new” features of the LLM will be further studied and understood in 2024. Also, things like LLM not being able to multiply large numbers would make more sense. At the same time, the returns on number of parameters also start to decrease, and while training a 500 billion parameter model might technically yield better results, the compute required to do so could probably be more effectively deployed. may be. A single monolithic model is unwieldy and expensive, whereas a combination of multiple experts (a collection of smaller, more specific and perhaps multimodal models) is much easier to update in parts. However, it may prove to be nearly as effective.
Marketing meets reality
The simple fact is that it will be very difficult for companies to live up to the hype built in 2023. Marketing claims about machine learning systems that companies deploy to keep up will be subject to quarterly and annual reviews…and there is a strong possibility that they will be found to be inadequate. It is high. We expect significant customer withdrawal from AI tools as the benefits do not justify the costs and risks. At the other end of the spectrum, we may see litigation and regulatory action with AI service providers who are unable to substantiate their claims. Capabilities will continue to grow and advance, but it is not far off that all 2023 products will survive, and there will be a round of consolidation as the wave’s erratic riders decline and are consumed.
When a strong laser pulse hits a steel alloy, the material briefly melts where it is irradiated, forming a small magnetic region.Credit: HZDR / Sander Munster
The research team has shown that ultrashort laser pulses can magnetize iron alloys. This discovery has great potential for applications in magnetic sensor technology, data storage, and spintronics.
To magnetize a steel nail, simply stroke its surface several times with a bar magnet. But there is a more unusual method. it is, Helmholtz – Zentrum Dresden – Rossendorf (HZDR) Some time ago, a certain iron was discovered. alloy It can be magnetized with ultrashort laser pulses. The researchers are currently working with the Laser Institute of Mitweida University (LHM) to further investigate this process. They found that this phenomenon also occurs in different classes of materials. This greatly expands the range of potential applications.The working group will publish its results in a scientific journal Advanced functional materials.
Groundbreaking discovery in magnetization
An unexpected discovery was made in 2018. When the HZDR team bombarded a thin layer of iron and aluminum alloy with ultrashort laser pulses, the nonmagnetic material suddenly became magnetic. Explanation: Laser pulses rearrange the atoms in the crystal so that the iron atoms are closer to each other, forming a magnet. The researchers were then able to demagnetize the layer again using a series of weaker laser pulses. This allowed them to discover how to create and erase tiny “magnetic spots” on surfaces.
However, the pilot experiment still left some questions unanswered. “It was unclear whether the effect only occurs in iron-aluminum alloys or in other materials,” explains HZDR physicist Dr. Rantei Bali. “We also wanted to track the process over time.” For further investigation, he collaborated with his Dr. Theo Pflug at LHM and colleagues at the University of Zaragoza in Spain.
Flipbook using laser pulse
Experts especially focused on iron-vanadium alloys. Unlike iron-aluminum alloys, which have a regular crystal lattice, the atoms in iron-vanadium alloys are more randomly arranged, forming an amorphous glass-like structure. To observe what happens during laser irradiation, physicists used a special method called the pump-probe method.
“First, we bombard the alloy with powerful laser pulses to magnetize the material,” explains Theo Pflug. “At the same time, he uses a second, weaker pulse that is reflected off the material surface.”
Analysis of reflected laser pulses reveals the physical properties of the material. This process is repeated several times to continually lengthen the time interval between the first “pump” pulse and subsequent “probe” pulses.
As a result, time-series reflection data are obtained, which can characterize the processes induced by laser excitation. “The whole procedure is similar to creating a flipbook,” he says Pflug. “Similarly, a series of individual images that animate when viewed in succession.”
rapid dissolution
Results: Although they have a different atomic structure than iron-aluminum compounds, iron-vanadium alloys can also be magnetized by lasers. “In both cases, the material melts for a short time at the point of irradiation,” he explains Rantej Bali. “This causes the laser to erase the previous structure and create small magnetic regions in both alloys.”
Promising results: Apparently, this phenomenon is not limited to a particular material structure and can be observed in a variety of atomic arrangements.
The team also tracks the temporal dynamics of the process. “At least we know on what time scale something will happen,” explains Theo Pflug. “Within femtoseconds, a laser pulse excites electrons in the material. After a few picoseconds, the excited electrons transfer their energy to the nucleus.”
Consequently, this energy transfer causes a rearrangement into a magnetic structure, which is then stabilized by rapid cooling. In follow-up experiments, the researchers aim to observe exactly how the atoms rearrange by examining the magnetization process with powerful X-rays.
Perspectives towards applications
Although still in its early stages, this research already provides a first idea of possible applications. For example, one could place small magnets on the chip surface via a laser. “This could be useful in producing highly sensitive magnetic sensors such as those used in vehicles,” he speculates Rantej Bali. “It could also have applications in magnetic data storage.”
Moreover, this phenomenon seems to be related to a new type of electronics: spintronics. Here, instead of electrons passing through transistors as usual, magnetic signals must be used for digital computing processes, providing a possible approach to future computer technology.

Consumers are seeking new ways of social networking that prioritize trust, safety, and decentralization, rather than being controlled by big tech CEOs. Mozilla, the mission-driven technology company behind the Firefox browser and other apps, is investing in the “Fediverse.” The Fediverse is a network of decentralized social networking applications, like Mastodon, that communicate with each other through the ActivityPub protocol. Mozilla believes that current social networks, dominated by large companies and driven by profit, do not always prioritize consumer needs. This belief has been reinforced by events such as Elon Musk buying his Twitter account and launching alternative apps like Mastodon and Bluesky. As a non-profit subsidiary, Mozilla is not motivated by profit and aims to create a collaborative approach that incorporates diverse opinions. Mozilla’s involvement in the Fediverse, particularly with Mastodon, is driven by their dissatisfaction with the harmful content and profit-focused models of incumbent social media companies. Consumers are also growing more aware of these issues and seeking alternatives. While Mozilla aims to compete in the social networking space, their broader goal is to help the Fediverse gain traction and provide users with choice and agency. Mozilla plans to address obstacles to joining the Fediverse, such as technical hurdles and content discovery, through enhancements and features. They are currently experimenting with a private beta version of the Mozilla.Social Mastodon server and plan to roll out additional features gradually. Mozilla also aims to meet the needs of creators and publishers by creating conversations and experiences around high-quality content and building connections to help them reach their audiences. They want to improve the onboarding process and facilitate the formation of communities within the Fediverse. Trust and security are paramount, and Mozilla has strict content policies in place to ensure a safe environment. Overall, Mozilla’s involvement in the Fediverse is driven by their belief in a better way of social networking that prioritizes consumer needs and fosters trust and safety.
