  • Space, Tech, And AI: What Astronaut Tim Peake Can Teach Us About The Future Of Humanity

    Space, Tech, And AI: What Astronaut Tim Peake Can Teach Us About The Future Of Humanity

    When you’ve spent 6 months orbiting Earth in the International Space Station, your perspective on the planet and its problems is likely to change forever. Few people understand this more intimately than Tim Peake, the British astronaut, test pilot, and ambassador for STEM (Science, Technology, Engineering and Mathematics) education, who joined me for a fascinating conversation about space, AI, and the future of life on Earth.

    What struck me most in our conversation was how clearly Tim connects the dots between space exploration and the challenges we face on Earth, drawing on his remarkable experience and expertise. Whether it’s the climate crisis, the energy transition, or the role of AI in decision-making, space is not some distant frontier. It is deeply entangled with our present and our future.

    Looking Down On Earth From Orbit

    Peake vividly describes the emotional and intellectual impact of seeing our planet from above.

    “It gives you a fresh appreciation of how isolated and remote the planet is,” he told me. “A lot of people say fragile. I caution against using that word because I think the Earth’s pretty robust. But in terms of being remote and isolated, it makes you realize that this small rock is perfectly designed to support the life that has evolved on it.”

    And while the view from orbit can feel peaceful and serene, it’s also a powerful reminder of just how interconnected and dynamic our ecosystems really are. From wildfires in one region to dust storms in another, the visible signs of global interdependence are unmistakable from space.

    Peake explained, “You see wildfires and the smoke spreading across continents. You see sandstorms in the Sahara drifting across Northern Europe. That’s because the atmosphere is so thin, so tiny, and you see that very clearly from space.”

    The Promise Of Space-Based Technology

    Beyond the view, Peake is just as excited about what space can do for us back on Earth. Advances in manufacturing, communications, and energy are all being accelerated by what’s happening in orbit.

    One of the most compelling developments he pointed to is space-based manufacturing. In the absence of gravity, new kinds of structures can be created with unprecedented purity and precision.

    “For example, we can grow very large protein crystals in space that you can’t grow on Earth,” he said. “That can help pharmaceutical companies create better drugs with fewer side effects and lower dosages. Or if you’re trying to print out a human heart, doing that on Earth needs some sort of scaffolding. In space, gravity is not distorting the cellular structure.”

    He also believes that space-based solar power is not just science fiction. It could soon become a meaningful contributor to our global energy mix.

    “If we can make two-kilometer square solar arrays that beam energy back to Earth using microwaves, we can reduce the pressure on our grid and use space to help solve the energy crisis,” Peake explained.

    The falling cost of getting into orbit is a key enabler. As heavy-lift launch costs continue to drop, opportunities that once sounded fantastical, like factories in space or orbital data centers, suddenly look commercially viable.

    AI, Space Missions, And Human Judgment

    Naturally, we also discussed artificial intelligence. Peake believes that AI has a crucial role to play in helping humanity manage the deluge of data coming from satellites, sensors, and scientific instruments.

    “AI can analyze vast amounts of data and make good assumptions from it,” he said. “If a government is introducing a carbon emission policy in a city, AI can help measure the impact, evaluate the policy, and improve it based on outcomes.”

    But Peake also emphasized the continued need for human oversight. When it comes to critical decisions, especially in high-stakes environments like space missions or healthcare, humans must remain in the loop.

    “If you’re screening for breast cancer, for example, AI can assist doctors. But you still want the diagnosis coming from a person,” he said. “As humans, we like that reassurance. We want someone to put their intelligence on top of the AI’s assessment.”

    In other words, AI is not a replacement for human decision-making but a powerful augmentor, especially in environments where timely action matters.

    Why The Future Needs STEM… And STEAM

    Throughout our conversation, one theme kept coming up: the importance of inspiring the next generation, especially around STEM. For Peake, this is not a side mission; it’s central to why he does what he does.

    “I try to encourage kids to get involved in STEM, even if they don’t see themselves taking it to higher education,” he said. “The more you know about science and tech today, the more doors it opens for your future.” One initiative doing an outstanding job of sparking that curiosity is the Future Lab at the Goodwood Festival of Speed, where Peake serves as an ambassador. Curated by Lucy Johnston, the Future Lab showcases cutting-edge innovations from across the globe, from robotic rescue dogs and deep-sea exploration tools to mind-blowing space tech like the James Webb Space Telescope. “It’s hands-on, inspiring, and brilliantly curated,” Peake said. “You see people of all ages walking around in awe, and that’s exactly the kind of experience that can ignite a lifelong passion for science and technology.”

    Having taken my own son to Future Lab, I can say with certainty that it works. There’s something magical about seeing kids light up as they touch, feel, and interact with the technology that’s shaping tomorrow.

    The Space Economy Is Already Here

    Another eye-opener in our chat was just how much space already affects daily life. “On average, everyone touches about 42 satellites a day,” Peake said. Whether it’s making an online purchase, using navigation, or checking the weather, you’re using space infrastructure.

    And that footprint is only growing. Companies are already working on putting data centers in orbit to reduce energy consumption and cooling requirements on Earth. Communications, navigation, Earth observation, and climate monitoring are all becoming more dependent on space-based assets.

    But with growth comes risk. Peake is also an ambassador for The Astra Carta, an initiative supported by King Charles aimed at ensuring space is used sustainably. Space debris, orbital traffic, and light pollution are becoming serious issues.

    “We need rules of the road for space,” he said. “If we want to keep using it safely, we need to manage how we operate up there.”

    Reaching Beyond Earth And Into The Unknown

    As we wrapped up our conversation, I asked Tim the big one: Does he believe there’s intelligent life out there?

    “I absolutely do,” he said without hesitation. “Statistically, the odds are too strong. When you’re in space, and you see 200 billion stars in our galaxy alone, and then remember there are hundreds of billions of galaxies, it’s hard to believe we’re alone.”

    He also believes that space exploration will help answer some of the biggest questions humanity has ever asked about life, existence, and our place in the universe. But even if we don’t find extraterrestrials any time soon, the journey itself has value.

    Space inspires. It informs. And, increasingly, it enables.

    That, I think, is what makes Peake’s perspective so valuable. He’s lived at the intersection of science, technology, and wonder. And he reminds us that the frontier of space is not just about what lies out there but about what it can help us achieve here on Earth.

  • Paddling 30,000 years into the past: Scientists replicate prehistoric seafaring with a primitive canoe

    Paddling 30,000 years into the past: Scientists replicate prehistoric seafaring with a primitive canoe

    • Canoe is paddled 140 miles (225km) across the open sea
    • The journey is from Taiwan to Japan’s Yonaguni Island
    • Research is reminiscent of famed 1947 Kon-Tiki expedition

    TOKYO, June 30 — Our species arose in Africa roughly 300,000 years ago and later trekked worldwide, eventually reaching some of Earth’s most remote places. In doing so, our ancestors surmounted geographic barriers including treacherous ocean expanses. But how did they do that with only rudimentary technology available to them?

    Scientists now have undertaken an experimental voyage across a stretch of the East China Sea, paddling from Ushibi in eastern Taiwan to Japan’s Yonaguni Island in a dugout canoe to demonstrate how such a trip may have been accomplished some 30,000 years ago as people spread to various Pacific Islands.

    The researchers simulated methods Palaeolithic people would have used and employed replicas of tools from that prehistoric time period such as an axe and a cutting implement called an adze in fashioning the 25-foot-long (7.5-metre) canoe, named Sugime, from a Japanese cedar tree chopped down at Japan’s Noto Peninsula.

    Researcher Kunihiro Amemiya uses a period-accurate axe to chop down a Japanese cedar tree in Noto Peninsula, Japan, to make a dugout canoe for a crossing across a region of the East China Sea from Taiwan to Yonaguni Island, in this handout image released on June 25, 2025. — Yousuke Kaifu handout pic via Reuters

    A crew of four men and one woman paddled the canoe on a voyage lasting more than 45 hours, traveling roughly 140 miles (225km) across the open sea and battling one of the world’s strongest ocean currents, the Kuroshio. The crew endured extreme fatigue and took a break for several hours while the canoe drifted at sea, but managed to complete a safe crossing to Yonaguni.

    Just as prehistoric people would have, the voyagers navigated by the sun and stars, as well as the direction of the ocean swells, though for safety’s sake they were accompanied by two escort craft. Yonaguni is part of the Ryukyu chain of islands stretching from Kyushu, the southernmost of Japan’s four main islands, down to Taiwan.

    The researchers previously failed with attempted crossings using reed rafts and then bamboo rafts, finding that they were too slow, insufficiently durable and unable to overcome the strong ocean current.

    “Through the project with many failures, we have learned the difficulties of crossing the ocean, and this experience gave us a deep respect for our Palaeolithic ancestors,” said University of Tokyo anthropologist Yousuke Kaifu, lead author of the study published on Wednesday in the journal Science Advances.

    “We found that the Palaeolithic people could cross the sea with the strong ocean current if they had dugout canoes and were skilful, experienced paddlers and navigators. They had to face the risk of being drifted by the strong ocean current and the possibility that they would never be able to come back to their homeland,” added Kaifu, who was aboard one of the escort boats.

    Archaeological evidence indicates that people approximately 30,000 years ago first crossed from Taiwan to some of the Ryukyu islands, which include Okinawa. But scientists had puzzled over how they could do this with the rudimentary technology of the time — no maps, no metal tools and only primitive vessels. And the Kuroshio current, comparable in strength to the Gulf Stream off Mexico, presented a particular challenge.

    The research was in the vein of the famous 1947 Kon-Tiki expedition in which Norwegian explorer Thor Heyerdahl carried out a much longer journey by raft from South America across the Pacific to the Polynesian islands. Heyerdahl aimed to show how prehistoric people from the Americas could have colonised Polynesia.

    “His theory is now countered by a series of pieces of evidence, but it was a great trial at the time. Compared to the time of the Kon-Tiki, we have more archaeological and other evidence to build realistic models” of prehistoric voyages, Kaifu said.

    The researchers in a companion study published in the same journal used simulations of sea conditions between Taiwan and Yonaguni 30,000 years ago to examine whether such a crossing was attainable at a time when the Kuroshio was even more powerful than today.

    “As our paleo-ocean model simulation showed, crossing the Kuroshio was possible in ancient times, so I believe they achieved it,” said physical oceanographer and study lead author Yu-Lin Chang of the Japan Agency for Marine-Earth Science and Technology.

    “However, ocean conditions were highly variable. Thus, ancient people may have encountered unpredictable weather conditions during their journey, which could have led to failure,” Chang added. — Reuters

  • NASA exoplanet-hunting spacecraft and citizen scientists discover a cool new alien world

    NASA exoplanet-hunting spacecraft and citizen scientists discover a cool new alien world

    A new gas giant world discovered by citizen scientists using data from NASA’s exoplanet-hunting spacecraft TESS is cool, literally and figuratively.

    The extrasolar planet, or “exoplanet,” designated TOI-4465 b is located around 400 light-years from Earth. It has a mass of around six times that of Jupiter, and it’s around 1.25 times as wide as the solar system’s largest planet. What is really exciting about TOI-4465 b, however, is the fact that it circles its star at a distance of around 0.4 times the distance between Earth and the sun in a flattened or “elliptical” orbit. One year for this planet takes around 102 Earth days to complete. Its distance from its star gives it an estimated temperature of between 200 and 400 degrees Fahrenheit (93 to 204 degrees Celsius).

  • Labels Are Everything: New Study Reveals Role of Popularity in News Articles

    Labels Are Everything: New Study Reveals Role of Popularity in News Articles

    BYLINE: Savannah Peat

    Newswise — News readers often click on articles not based on topic but rather the behavior of their fellow audience members, according to new research from the University of Georgia.

    And the way that news organizations label those articles could directly influence how much attention they receive and ultimately impact their revenue.

    When you go to a news organization’s homepage, they typically label articles that readers are engaging with the most. The researchers focused on two common labels: “most shared” and “most read.” 

    “These types of labels are not going anywhere. Popularity even in news labels is a psychological phenomenon,” said Tari Dagago-Jack, lead author of the study and an assistant professor of marketing in the UGA Terry College of Business. “Popularity labels on news outlets are taking advantage of the idea that we follow the lead of others and that our decision-making is influenced by what other people are doing.”

    Article section labels influence click rate

    At first glance, you may assume that these labels, “most shared” and “most read,” mean the same thing: A lot of people checked out the article. But there’s a clear difference that consumers pick up on.

    “If something is most shared, we might assume that means many people had to read it and then deem it interesting enough or important enough to pass it on,” Dagogo-Jack said. “But then there’s this other reality where we know a lot of things that are widely shared are often extremely frivolous like cat videos or funny memes.”

    In nine surveys and experiments involving hundreds of people, the study found respondents interpreted “most read” stories as being more informative. “Most shared” articles were viewed as less serious and more entertainment based.

    “The primary goal for reading news is to gain information, and the label ‘most read’ is a stronger signal of an article’s information value.” —Tari Dagago-Jack, Terry College

    “We as readers have two primary motives: to be informed or to be entertained — that is, for a welcome diversion,” said Dagogo-Jack. “At a baseline level, we were finding that people were choosing ‘most read’ at a way higher rate than ‘most shared.’ The primary goal for reading news is to gain information, and the label ‘most read’ is a stronger signal of an article’s information value.”

    That means if editors want certain articles to get more attention, they should tailor the label to the readers’ goals.

    Knowing your audience, content is key for engagement

    The same went for articles advertised on social media. Posts from faux news organizations that had captions describing a more educational article as “most shared” received fewer clicks.

    This wasn’t the case, however, for news stories that were less serious and newsworthy. In that case, the “most shared” label worked as well as the “most read” label.

    It’s a key message for reporters, editors and web developers: Know your audience and your content.

    “People should ask themselves: Why am I even clicking on this thing? Is it just because everyone else read it?” —Tari Dagago-Jack

    “For pop culture, sports or music — more entertainment — in those sections you should highlight what is ‘most shared,’” Dagogo-Jack said. “But for world news, politics and science sections, you should be using things like ‘most read’ or ‘most viewed.’”

    Dagogo-Jack also recommends putting thought into labels. Ambiguous choices like “trending” or “most popular” may stump readers altogether, as there are so many things this could mean.

    “Providing these lists helps us get over information overload or choice paralysis,” he said. “It’s a crutch and makes the decision process easier, but I often wonder: At what cost?

    “You’re clicking on something that a lot of people like and social proof is valuable, but it may not necessarily provide what you are looking for, and you just gave up on the search. People should ask themselves: Why am I even clicking on this thing? Is it just because everyone else read it?”

    This study was published in the Journal of Consumer Research and was co-authored by New York University assistant professor Jared Watson.

  • How can the James Webb Space Telescope see so far?

    How can the James Webb Space Telescope see so far?

    Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to CuriousKidsUS@theconversation.com.


    How does the camera on the James Webb Space Telescope work and see so far out? – Kieran G., age 12, Minnesota


    Imagine a camera so powerful it can see light from galaxies that formed more than 13 billion years ago. That’s exactly what NASA’s James Webb Space Telescope is built to do.

    Since it launched in December 2021, Webb has been orbiting more than a million miles from Earth, capturing breathtaking images of deep space. But how does it actually work? And how can it see so far? The secret lies in its powerful cameras – especially ones that don’t see light the way our eyes do.

    I’m an astrophysicist who studies galaxies and supermassive black holes, and the Webb telescope is an incredible tool for observing some of the earliest galaxies and black holes in the universe.

    When Webb takes a picture of a distant galaxy, astronomers like me are actually seeing what that galaxy looked like billions of years ago. The light from that galaxy has been traveling across space for the billions of years it takes to reach the telescope’s mirror. It’s like having a time machine that takes snapshots of the early universe.

    By using a giant mirror to collect ancient light, Webb has been discovering new secrets about the universe.

    A telescope that sees heat

    Unlike regular cameras or even the Hubble Space Telescope, which take images of visible light, Webb is designed to see a kind of light that’s invisible to your eyes: infrared light. Infrared light has longer wavelengths than visible light, which is why our eyes can’t detect it. But with the right instruments, Webb can capture infrared light to study some of the earliest and most distant objects in the universe.

    Infrared cameras, like night-vision goggles, allow you to ‘see’ the infrared waves emitting from warm objects such as humans and animals. The temperatures for the images are in degrees Fahrenheit.

    Although the human eye cannot see it, people can detect infrared light as a form of heat using specialized technology, such as infrared cameras or thermal sensors. For example, night-vision goggles use infrared light to detect warm objects in the dark. Webb uses the same idea to study stars, galaxies and planets.

    Why infrared? When visible light from faraway galaxies travels across the universe, it stretches out. This is because the universe is expanding. That stretching turns visible light into infrared light. So, the most distant galaxies in space don’t shine in visible light anymore – they glow in faint infrared. That’s the light Webb is built to detect.

    A golden mirror to gather the faintest glow

    Before the light reaches the cameras, it first has to be collected by the Webb telescope’s enormous golden mirror. This mirror is over 21 feet (6.5 meters) wide and made of 18 smaller mirror pieces that fit together like a honeycomb. It’s coated in a thin layer of real gold – not just to look fancy, but because gold reflects infrared light extremely well.

    The mirror gathers light from deep space and reflects it into the telescope’s instruments. The bigger the mirror, the more light it can collect – and the farther it can see. Webb’s mirror is the largest ever launched into space.

    Inside the cameras: NIRCam and MIRI

    The most important “eyes” of the telescope are two science instruments that act like cameras: NIRCam and MIRI.

    NIRCam stands for near-infrared camera. It’s the primary camera on Webb and takes stunning images of galaxies and stars. It also has a coronagraph – a device that blocks out starlight so it can photograph very faint objects near bright sources, such as planets orbiting bright stars.

    NIRCam works by imaging near-infrared light, the type closest to what human eyes can almost see, and splitting it into different wavelengths. This helps scientists learn not just what something looks like but what it’s made of. Different materials in space absorb and emit infrared light at specific wavelengths, creating a kind of unique chemical fingerprint. By studying these fingerprints, scientists can uncover the properties of distant stars and galaxies.

    MIRI, or the mid-infrared instrument, detects longer infrared wavelengths, which are especially useful for spotting cooler and dustier objects, such as stars that are still forming inside clouds of gas. MIRI can even help find clues about the types of molecules in the atmospheres of planets that might support life.

    Both cameras are far more sensitive than the standard cameras used on Earth. NIRCam and MIRI can detect the tiniest amounts of heat from billions of light-years away. If you had Webb’s NIRCam as your eyes, you could see the heat from a bumblebee on the Moon. That’s how sensitive it is.

    NASA

    Because Webb is trying to detect faint heat from faraway objects, it needs to keep itself as cold as possible. That’s why it carries a giant sun shield about the size of a tennis court. This five-layer sun shield blocks heat from the Sun, Earth and even the Moon, helping Webb stay incredibly cold: around -370 degrees F (-223 degrees C).

    MIRI needs to be even colder. It has its own special refrigerator, called a cryocooler, to keep it chilled to nearly -447 degrees F (-266 degrees C). If Webb were even a little warm, its own heat would drown out the distant signals it’s trying to detect.

    Turning space light into pictures

    Once light reaches the Webb telescope’s cameras, it hits sensors called detectors. These detectors don’t capture regular photos like a phone camera. Instead, they convert the incoming infrared light into digital data. That data is then sent back to Earth, where scientists process it into full-color images.

    The colors we see in Webb’s pictures aren’t what the camera “sees” directly. Because infrared light is invisible, scientists assign colors to different wavelengths to help us understand what’s in the image. These processed images help show the structure, age and composition of galaxies, stars and more.

    By using a giant mirror to collect invisible infrared light and sending it to super-cold cameras, Webb lets us see galaxies that formed just after the universe began.

  • New database maps olfactory gene diversity across chordates

    New database maps olfactory gene diversity across chordates

    CORD: A Comprehensive Portal into Chordate Olfactory Receptors.

    GA, UNITED STATES, June 30, 2025 /EINPresswire.com/ — How animals sense and respond to smells plays a pivotal role in their survival, communication, and evolution. Recently, a groundbreaking online database has compiled the most expansive collection of olfactory receptor (OR) genes ever assembled in chordates—animals with backbones. Encompassing over 1.1 million sequences across nearly 2,800 species, this resource offers a unified platform for exploring both functional genes and pseudogenes. It integrates advanced tools for visualizing molecular structures, mapping odor interactions, and analyzing evolutionary relationships. With its comprehensive design, the database opens new avenues for researchers to decode how animals perceive chemical cues and adapt to diverse ecological environments.

    Olfactory receptors (ORs) are key to how animals perceive their surroundings, guiding behaviors like foraging, mating, and avoiding danger. In chordates, the genes encoding these receptors are remarkably diverse and evolve rapidly, shaped by species-specific environmental pressures. Despite the explosion of genomic data in recent years, the annotation of these genes has struggled to keep pace. Many species still lack reliable OR gene catalogs, and most existing databases focus narrowly—often omitting pseudogenes or comparative frameworks. These limitations hinder the broader understanding of OR gene function and evolution. Due to these issues, a comprehensive and scalable platform for OR annotation and integration is urgently needed.

    To meet this need, researchers from ShanghaiTech University and Research Center for Life Sciences Computing, Zhejiang Lab, etc. have developed the chordata olfactory receptor database (CORD), published (DOI: 10.1093/procel/pwae050) in Protein & Cell on September 20, 2024. The online platform compiles and standardizes more than 1.1 million OR gene entries from 2,776 chordate species, offering a massive leap in the coverage, consistency, and accessibility of olfactory genomic data. By integrating functional receptors, pseudogenes, and odorant-interaction data, CORD sets a new benchmark for studying the genetic basis of smell across evolutionary lineages.

    At the heart of CORD lies Genome2OR, a high-performance gene annotation tool built on hidden Markov models. Its latest update simplifies the annotation pipeline and supports custom profiles, enabling the accurate identification of over 663,000 functional ORs and more than 513,000 pseudogenes. The database spans seven major chordate groups—from mammals and birds to jawless fish—highlighting the evolutionary richness of olfactory systems. CORD’s interface is designed with researchers in mind, featuring nine functional modules for genome browsing, structural prediction, and comparative analysis. Tools include BLAST search, sequence logos (WebLogo), and OpenFold-based 3D modeling. Users can explore complex gene–odorant relationships, supported by 3,118 receptor–ligand pairs and data on nearly 24,000 odorant compounds. Advanced visualization techniques such as snake diagrams and interactive heatmaps reveal how ORs are structured and distributed across species. Further, protein clustering datasets (CORDclust30–90) and community network analysis offer new insight into OR gene families and their evolutionary pathways. Altogether, CORD blends depth with usability, empowering researchers to unravel the biology of smell with unprecedented precision.

    Scent is one of the most ancient and intricate senses, said Dr. Suwen Zhao, one of the co-corresponding authors. Yet until now, researchers lacked a unified, scalable tool to study the extraordinary diversity of ORs in chordates. CORD fills this gap. It not only delivers a vast quantity of high-quality data, but it also makes that data discoverable and usable across disciplines—from molecular neuroscience to comparative genomics. Dr. Zhao highlighted the database’s potential to illuminate how olfactory genes function beyond the nose, impacting broader biological processes.

    With its wide-ranging data and flexible interface, CORD is poised to transform multiple research fields. Evolutionary biologists can now trace how OR gene repertoires expand and contract across ecological niches. Biomedical researchers gain a new tool to study the role of ORs in conditions like inflammation, metabolic disorders, and cancer—where these receptors are increasingly found outside the nose. In computational biology, CORD’s modular structure supports machine learning applications for modeling protein–ligand interactions. Future updates will incorporate experimentally derived OR structures, integrate AlphaFold3-based odor–receptor simulations, and launch a genome browser to map gene neighborhoods. By unifying data and tools under one roof, CORD is set to propel olfaction research into its next frontier.

    NIT Rourkela-led study reveals how dust and ice shape Mars’ atmosphere

    The study focused on three major elements of Martian weather: dust devils, small spinning columns of air…

    Representational Image | Photo: AP/NASA 

    New Delhi: In a groundbreaking study, an international team of researchers led by the National Institute of Technology (NIT) Rourkela has explored the impact of spinning dust devils, massive dust storms, and extensive water-ice clouds on the Martian atmosphere. Collaborating with scientists from the UAE University and Sun Yat-sen University in China, the team analysed more than two decades of data from multiple Mars missions, including India’s Mars Orbiter Mission (MoM).

    Understanding these processes will also help in preparing for human exploration missions. Knowing how Martian weather works can help protect spacecraft, support future astronauts, and improve our understanding of whether Mars may once have supported life, said the researchers in the paper published in the prestigious journal New Astronomy Reviews.

    “Advancing the weather prediction on Mars is not just a scientific pursuit; it is the cornerstone of ensuring that future missions can sustain there and realise the past and future habitability of the red planet,” said Prof. Jagabandhu Panda, Professor at the Department of Earth and Atmospheric Sciences, NIT Rourkela.

    Mars, also known as the Red Planet, is home to some of the most dramatic weather systems in the solar system. The dust raised by local and regional storms can travel far and disturb wind patterns, resulting in changes in temperatures and some cases, reshaping the Martian atmosphere in dramatic ways.

    The study focused on three major elements of Martian weather: dust devils, small spinning columns of air that are common during the summer and more frequent in the northern hemisphere; large dust storms, driven by a loop in which sunlight heats the dust, and can grow to cover entire regions or even the whole planet; water-ice clouds, thin, wispy clouds made of frozen water particles.

    Using imaging data from over 20 years, the researchers have traced how changing seasons on Mars affect the dust and cloud formation and movement. These findings refine human knowledge and understanding of Mars’ climate system and may be useful for predicting future weather on the planet.

    As more missions head to the Red Planet, long-term studies like this one offer essential clues about its ever-changing skies.

    “It would be great if ISRO could conduct more missions to Mars and invest more in the university system to carry out such research. It will help in advancing science and technology further,” Panda said. IANS

    Liquid metal used in novel circuit board scan self-heal and work after taking heavy damage

    A new type of self-healing and reconfigurable circuit board can withstand heavy damage and still work effectively, scientists say. It can even be completely recycled once it reaches the end of its life.

    The new breakthrough is owed to a material called a vitrimer, a special polymer capable of remaining rigid and durable at normal temperatures but malleable and reshapable at higher temperatures. The scientists outlined their findings in a new study published 1 June in the journal Advanced Materials.
