Scientists create new idea on how to hack a warming planet: drying the upper atmosphere
Government scientists have cooked up a new concept for how to potentially cool an overheating Earth: Fiddle with the upper atmosphere to make it a bit drier......»»
Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown by scientists at Tokyo Tech to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation......»»
Human activity: A double-edged sword in the face of drought
Earth and environmental scientists have reported that, as human socio-economic activities increase, greenhouse gas emissions will rise, leading to more frequent extreme weather events such as droughts and floods. However, a research team from Pohang.....»»
Exploring the roots of the Anthropocene
Understanding how tropical land use and deforestation affects the dynamics of the global Earth system and identifying potential tipping points are key to the future of our species on this planet. By exploring the long history of human societies in tr.....»»
Study challenges popular idea that Easter islanders committed "ecocide"
Some 1,000 years ago, a small band of Polynesians sailed thousands of miles across the Pacific to settle one of the world's most isolated places—a small, previously uninhabited island they named Rapa Nui. There, they erected hundreds of "moai," or.....»»
Scientists solve the puzzle of directional hearing underwater
When underwater, humans cannot determine where a sound comes from. Sound travels about five times faster there than on land. That makes directional hearing, or sound localization, nearly impossible because the human brain determines the origin of a s.....»»
I have a mysterious problem with my iPhone 15 Pro Max
I've had enough of the iPhone 15 Pro Max's unpredictable battery life, but I have no idea what needs to change for it to be fixed......»»
Science Is Full of Errors. Bounty Hunters Are Here to Find Them
A new project is paying researchers to find errors in other scientists’ work. The only problem? Even error hunters make mistakes......»»
Scientists use heart and lung model to calculate potential health threats facing future space tourists in microgravity
Space exploration has always captivated our imagination, offering the promise of discovering new worlds and pushing the boundaries of human capability. As commercial space travel becomes more accessible, individuals with various underlying health con.....»»
What happened when NASA simulated an asteroid hitting Earth
NASA ran the world's most dramatic roleplay, simulating what would happen if a dangerous asteroid were spotted on a collision course with the planet......»»
New insights into how cell shape influences protein transport rates
When a cell spreads out or changes its shape to adapt to its environment, the transport rate of proteins between the nucleus and cytoplasm changes. Previously, scientists assumed this change was caused by a shift in the size of the nuclear envelope's.....»»
Spectroscopic technique that singles out water molecules lying on the surface reveals how they relax after being excited
A more complete picture of how excited water molecules at an interface with air lose their energy has been uncovered by RIKEN scientists in a study published in the journal Nature Communications. This finding will be valuable for better understanding.....»»
Scientists discover surprising link between ancient biology and restricted human hair growth
University of Manchester scientists have linked one of the ways that cells respond to stressful conditions with restricted healthy hair growth......»»
New photonic chip spawns nested topological frequency comb
Scientists on the hunt for compact and robust sources of multicolored laser light have generated the first topological frequency comb. Their result, which relies on a small silicon nitride chip patterned with hundreds of microscopic rings, appears in.....»»
Why scientists are intrigued by air in NASA"s Mars sample tubes
Atmospheric scientists get a little more excited with every rock core NASA's Perseverance Mars rover seals in its titanium sample tubes, which are being gathered for eventual delivery to Earth as part of the Mars Sample Return campaign. Twenty-four h.....»»
Cleaning up cow burps to combat global warming
New tools for lowering methane emissions from livestock are on their way. Enlarge (credit: Tony C. French/Getty) In the urgent quest for a more sustainable global food system, livestock are a mixed blessing. On the one h.....»»
Citizen scientists gather eDNA in water samples for global biodiversity census
Kara Andres, a postdoctoral fellow with the Living Earth Collaborative at Washington University in St. Louis, collected samples of water from Simpson Lake, in Valley Park, Mo., as part of a coordinated global effort to use environmental DNA—genetic.....»»
Defunct satellites burning up in the atmosphere could damage the ozone layer
Communications companies such as Starlink plan to launch tens of thousands of satellites into orbit around Earth over the next decade or so. The growing swarm is already causing problems for astronomers, but recent research has raised another questio.....»»
Researchers uncover enzyme communication mechanism that could aid drug development
A mechanism that could help scientists harness enzymes for use in drug discovery has been discovered in a research breakthrough at the University of Birmingham......»»
AI can help forecast toxic "blue-green tides"
A team of Los Alamos National Laboratory scientists plan to use artificial intelligence modeling to forecast, and better understand, a growing threat to water caused by toxic algal blooms. Fueled by climate change and rising water temperatures, these.....»»
Researchers create power-generating, gel electret-based device for wearable sensors
A team of researchers from NIMS (National Institute for Materials Science), Hokkaido University and Meiji Pharmaceutical University has developed a gel electret capable of stably retaining a large electrostatic charge. The team then combined this gel.....»»
