Materials that are incredibly thin, only a few atoms thick, exhibit unique properties that make them appealing for energy storage, catalysis and water purification. Researchers have now developed a method that enables the synthesis of hundreds of new 2D materials.
A healthier diet is linked with a slower pace of aging, reduced dementia risk, study shows
A healthier diet is associated with a reduced dementia risk and slower pace of aging, according to a new study. The findings show that a diet-dementia association was at least partially facilitated by multi-system processes of aging. Until now, the biological mechanism of this protection was not well understood.
An electricity generator inspired by the drinking bird toy powers electronics with evaporated water
Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a new study.
Chimp moms play with their offspring through good times and bad
A recent study observing wild chimpanzees over a period of more than 10 years revealed that when food gets scarcer, the adults put play aside and focus on survival, while mother chimps continue to be their children's primary playmate -- suggesting their indispensable role to foster their young's physical and social development.
What kinds of seismic signals did Swifties send at LA concert?
Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic tremors.
Robot ANYmal can do parkour and walk across rubble
The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Cheers! NASA's Webb finds ethanol, other icy ingredients for worlds
What do margaritas, vinegar, and ant stings have in common? They contain chemical ingredients that NASA's James Webb Space Telescope has identified surrounding two young protostars known as IRAS 2A and IRAS 23385. Although planets are not yet forming around those stars, these and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds.
The future is likely less skiable, thanks to climate change
Annual snow cover days in all major skiing regions are projected to decrease dramatically as a result of climate change, with 1 in 8 ski areas losing all natural snow cover this century under high emission scenarios, according to a new study.
New high-speed microscale 3D printing technique
A new process for microscale 3D printing creates particles of nearly any shape for applications in medicine, manufacturing, research and more -- at the pace of up to 1 million particles a day.
Supply chain disruptions will further exacerbate economic losses from climate change
Global GDP loss from climate change will increase exponentially the warmer the planet gets when its cascading impact on global supply chains is factored in, finds a new study.
Menopause explains why some female whales live so long
Females of some whale species have evolved to live drastically longer lives so they can care for their families, new research shows.
Explaining a supernova's 'string of pearls'
Physicists often turn to the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but that may not be the full story when it comes to the ring of hydrogen clumps around supernova 1987A, research suggests. It looks like the same mechanism that breaks up airplane contrails might be at play in forming the clumps of hydrogen gas that ring the remnant of supernova 1987A.
New AI technology enables 3D capture and editing of real-life objects
Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.
Giant volcano discovered on Mars
A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars' equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration.
Scientists develop ultra-thin semiconductor fibers that turn fabrics into wearable electronics
Scientists have developed ultra-thin semiconductor fibers that can be woven into fabrics, turning them into smart wearable electronics.
Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change
Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.
Milk to the rescue for diabetics? Cow produces human insulin in milk
An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes.
Grounding zone discovery explains accelerated melting under Greenland's glaciers
Researchers have conducted the first large-scale observation and modeling study of northwest Greenland's Petermann Glacier. Their findings reveal the intrusion of warm ocean water beneath the ice as the culprit in the accelerated melting it has experienced since the turn of the century, and their computer predictions indicate that potential sea level rise will be much worse than previously estimated.
Alaska dinosaur tracks reveal a lush, wet environment
A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.
Study: Best way to memorize stuff? It depends...
Recent experiments by psychologists shed new light on how we learn and how we remember our real-world experiences. In two experiments, researchers asked participants to repeatedly study pairs of items and scenes that were either identical on each repetition or in which the item stayed the same but the scene changed each time. Researchers found that spaced learning benefited item memory, but they also found that memory was better for the items that had been paired with different scenes compared wi...
Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
A coral superhighway in the Indian Ocean
Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'
Scientists propose new theory that explains sand ripples on Mars and on Earth
Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Cheetahs' unrivalled speed explained by their 'sweet spot' size, finds Imperial study
A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.
Peering into the tendrils of NGC 604 with NASA's Webb
The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Nasa's Webb, Hubble telescopes affirm universe's expansion rate, puzzle persists
When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.
