Scientists develop a statistical fix for archaeology"s dating problem
Archeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there's never been.....»»
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.....»»
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......»»
Study shows rising temperatures affect air quality over Los Angeles
Particulate matter and ozone are a major problem for people and the environment. Dr. Eva Pfannerstill, young investigator group leader at Jülich's Institute of Energy and Climate Research (IEK 8), is investigating where the volatile organic compound.....»»
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.....»»
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.....»»
iPad power user tip: Hide the floating keyboard row so it won’t hide your content
When using an iPad with an external keyboard attached, iPadOS places a floating keyboard row at the bottom of your screen. Apple calls this the Shortcuts bar. The problem with the Shortcuts bar is that it often gets in the way of other important c.....»»
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.....»»
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.....»»
Q&A: New method confines light inside an organic material to form a hybrid quantum state
A team of international scientists led by the University of Ottawa have gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states......»»
Researchers develop novel AI algorithm for analyzing microfossils
Microfossil analysis allows us to map the subsurface and understand past geological times. In research labs all over the world, geologists spend countless hours looking through the microscope identifying and counting microfossils extracted from sedim.....»»
Recovering lost wages is nearly impossible for Australia"s underpaid migrant workers. Here"s how to fix the problem
