When physicists fire beams of fast electrons at materials, they often need to know exactly how much energy those electrons will lose as they travel through. Through new research published in Physical Review Letters, a team led by Ke Jiang at Shenzhen Technology University in
Tenets of quantum mechanics and special relativity, among other theoretical ideas, lead inexorably to string theory.
Alaska's Cook Inlet was home to nearly 1,300 beluga whales in the late 1970s, but today the population hovers around 300. Despite almost two decades of recovery work, the whales aren't bouncing back. The Cook Inlet belugas are likely struggling under multiple pressures,
When you hear the word "epoxide," what do you think? If anything, likely "glue." But epoxides are quite common in our everyday lives. You might be sitting on a foam seat cushion made from epoxides. There is a good chance the synthetic textiles in your clothing involve epoxides
Big corporations are not just influenced by governments anymore—they are being increasingly influenced by the military, according to a new study from the University of Surrey. The research, published in the Journal of World Business, shows many multinational firms now build
Seasonal influenza can spread rapidly, and timely information on rising cases is essential for public health decisions and health care resource planning. However, conventional surveillance based on reported patients can lag behind real-world infection trends because it depends
You're an anaerobic microbe sunbathing on a Martian beach billions of years ago listening to the small waves hit the shoreline as you take in the perchlorates in the Martian regolith. This is because while Mars is warm and wet, it still lacks sufficient oxygen, so anaerobic
In the spring of 2025, baseball fans were treated to a surprise when the New York Yankees began the season with a unique style of bat. Termed "torpedo bats," these new designs tapered slightly toward the end, so the widest points of the bats were closer to the "sweet spot"—the
New research shows how climate change is reshaping protected area management, though more funding and scientific knowledge are needed to facilitate the process. The Natura 2000 network, the world's largest network of protected areas, aims at protecting important species and
Researchers at the University of Bristol have developed a new method which could help scientists perform large-scale climate simulations at a fraction of the cost and time needed compared to traditional climate models. The team, led by Dr. Charles Williams, Senior Lecturer in
In Olympic weightlifting, a single kilogram plate can be the difference between gold and silver. As much as possible, elite athletes must use everything they can to their advantage.
Every year in the West Pacific, as summer ends and September rolls around, typhoons are not far behind. Typhoons are the most impactful extreme weather events affecting Japan and East Asia, and due to climate change, extremely strong typhoons are becoming more frequent. In

In 2012, a wildfire ripped through 42 square kilometers of alpine moorland in Africa's Rwenzori Mountains, a range of glaciated peaks on the border of Uganda and the Democratic Republic of Congo. The blaze, which occurred at an elevation of over 13,000 feet, was shocking to
How do fish survive relentless sunlight in the open waters without getting burned? They make their own natural sunscreen—and now, humans could be one step closer to using it too.
Our personal identity is composed of many dimensions, such as age, gender, ethnic background, or socioeconomic status. A research team led by Fariba Karimi from the Institute of Human-Centered Computing at Graz University of Technology (TU Graz) and Samuel Martin-Gutierrez from
It's a tough world for microbes. When resources grow limited and environments worsen, microbes have figured out ways to hunker down and go dormant until conditions improve.
A Dartmouth study shows that annual rainfall in much of the world has consolidated over the past four decades into heavier storms with longer dry periods in between.
It's been 37 years since scientists first demonstrated the ability to move single atoms, suggesting the possibility of designing materials atom by atom to customize their properties. Today there are several techniques that allow researchers to move individual atoms in order to
Scientists from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences have uncovered new information suggesting a potential connection between Homo erectus and modern humans, while also developing new, less invasive
Mapping their starting point like bees do helps autonomous drones find their way
It’s evolved far beyond a rotten apple The post The Genetic Secrets of the Fruit Fly That Hunts Its Prey appeared first on Nautilus .
Many drug and antibody discovery pathways focus on intricately folded cell membrane proteins. When molecules of a drug candidate bind to these proteins, like a key going into a lock, they trigger chemical cascades that alter cellular behavior. Understanding how proteins fold
In many primate species, males are much larger than their female counterparts, which is generally attributed to male competition for mates (sexual selection). But bigger bodies may not just be about alpha males defeating rivals. They could also come about because of competition
A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful plaque buildup associated with
The impacts were severe: Within a very short time, tropical storm Doksuri intensified into a super typhoon in July 2023. Exceptionally strong winds tore roofs from houses along the coasts of China and the Philippines, trees were uprooted, and torrential rain flooded streets and
When you think of outer space, you're likely picturing stars, planets and moons. But much of space is filled with clouds of gas, plasma and stardust—known as interstellar clouds.
As debate intensifies over data center construction and how to regulate artificial intelligence (AI), a new nationally representative survey finds that Americans are broadly pessimistic about the impact of AI and want more government action to regulate the technology.
Africa’s Turkana Rift Zone, a hotbed of hominin fossils, is caught in the act of “necking," a critical transition toward continental breakup.
Last night, Labor unveiled a budget designed to tackle intergenerational equity in Australia through bold tax reform. It comes at a time when politics is consumed with the international shocks created by US President Donald Trump, whether through chaotic tariff announcements or
For nearly 100 years, reinforced rubber has powered everything from car tires to airplanes, yet scientists never fully understood why adding tiny particles of carbon black made rubber so incredibly strong. Now, researchers at the University of South Florida have finally cracked
Researchers at the Technion have discovered how changes in genetic regulatory sequences can lead to alterations in the form and structure of animals—even when genetic regulatory systems are stable and resistant to change. The study, published in Science Advances, was led by Dr.
When third-year veterinary students at Cummings School of Veterinary Medicine at Tufts University step into the operating room to undertake their inaugural surgery, the energy in the room is palpable: there's excitement, but also nerves.
As modern technologies shrink to the nanoscale, surfaces increasingly dictate how materials deform, yield, and fail. Yet probing this regime has long been hindered by the challenge of preparing and controlling surfaces with true atomic precision, particularly at the outermost
Malaria incidence is increasing, progress on maternal mortality is stalling, and some childhood vaccine rates are plateauing or have dipped below the threshold for herd immunity
A medieval monk may have beaten Edmond Halley to one of astronomy’s greatest discoveries by nearly 700 years. Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989. At the time, comets were viewed as
Humans may have returned to Britain far earlier than scientists once believed — not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of reindeer and horses across a
Geological faults hold many secrets that may help us answer important questions about the nature of our planet and what really happens deep underground. One of the biggest mysteries lies within the Atotsugawa Fault System in Japan. What makes the area unusual is that, despite
When inorganic nanoparticles come together, their optical, electronic, and magnetic properties depend strongly on how they are arranged. Being able to reorganize these arrangements in a controlled way could therefore provide a powerful method for tuning material properties.
Describing new species can take decades. But scientists are working to identify new ways to speed up our understanding of this hidden biodiversity. By looking at the genetic data of thousands of beetle species, our researchers are able to reveal the true breadth of tropical
Government departments and other public bodies in the UK must consider requests to release information about AI-produced content, regulators have confirmed. The move follows a successful request by New Scientist for the release of a minister's ChatGPT logs
Medications are designed to treat diseased tissues while sparing healthy ones, often by attaching the drug to something that helps guide it directly to its target. But drugs also need time to work, which means they need to stay near the diseased tissues long enough.
More than 500 million years ago, during what is known as the Cambrian period, the seas and oceans on Earth were filled with a myriad of marine animals, many of which have now become extinct. This evolutionary burst in new forms of life, referred to as the Cambrian explosion,
People exposed to the Andes strain of the hantavirus may not develop symptoms for up to 42 days, a delay that makes tracing infections more difficult
With millions of people now using GLP-1 drugs such as Wegovy and Zepbound, scientists are racing to find ways to help people retain their weight loss after they stop taking the medication
Long-held assumptions tell us that atoms with the same number of protons, neutrons and electrons are indistinguishable, but one physicist wants to put this idea to the test
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside a crystal, while their centers of charge lie in
Are we really falling short on protein—or is the high-protein craze overblown?
Tropical forests store more than 60% of the world's vegetation biomass and are among the most important ecosystems for regulating the global carbon cycle and climate. However, their regulatory role is greatly influenced by the forests' carbon residence time—how long carbon
In a forest of pine and eucalyptus trees in central Portugal, chainsaws and diggers hum away clearing paths blocked by trees uprooted in winter storms, but the threat now is a high risk of summer fires.
