Chemical Pollution Has Passed Safe Limit For Humanity, Say Scientists
The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends, scientists have said. The Guardian reports: Plastics are of particularly high concern, they said, along with 350.....»»
Male or female? Scientists discover the genetic mechanism that determines sex development in butterflies
Scientists of the Biology Centre, Czech Academy of Sciences, in collaboration with University of Liverpool have found the genetic mechanism that determines whether individuals of the butterfly species Bicyclus anynana become male or female......»»
Economies take off with new airports: Research shows positive impacts of airport investments
Be it for work or vacation, chances are that many will have passed through an airport. In the largest cities, the airport presents to travelers the first glimpse of a new land and a reflection of the surrounding city. Beyond first impressions, airpor.....»»
Hungry, hungry white dwarfs: Solving the puzzle of stellar metal pollution
Dead stars known as white dwarfs, have a mass like the sun while being similar in size to Earth. They are common in our galaxy, as 97% of stars are white dwarfs. As stars reach the end of their lives, their cores collapse into the dense ball of a whi.....»»

Tweaking isotopes sheds light on promising approach to engineer semiconductors
Research led by scientists at the Department of Energy's Oak Ridge National Laboratory has demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening.....»»
Cold sintering may rescue plastic, ceramics, battery components from landfills
Recycling does not necessarily prevent an item from eventually ending up in a landfill, according to Enrique Gomez, interim associate dean for equity and inclusion and professor of chemical engineering in the Penn State College of Engineering. Instea.....»»
Physicists pioneer new quantum sensing platform
Quantum sensors detect the smallest of environmental changes—for example, an atom reacting to a magnetic field. As these sensors "read" the unique behaviors of subatomic particles, they also dramatically improve scientists' ability to measure and d.....»»
New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
Novel chemical tool for understanding membrane remodeling in the cell
In a study published in Proceedings of the National Academy of Sciences, Umeå researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell......»»
Novel triple drug combination effective against antibiotic-resistant bacteria
Scientists at the Ineos Oxford Institute (IOI) have found a new potential combination therapy to combat antimicrobial resistance (AMR) by targeting two key bacterial enzymes involved in resistance. The study, "The Triple Combination of Meropenem, Avi.....»»
Nepal court orders limit on Everest climbing permits
Nepal's Supreme Court has ordered the government to limit the number of mountaineering permits issued for Everest and other peaks, a lawyer confirmed Friday, just as expeditions prepare for the spring climbing season......»»
Mini Settlers is a city builder that you can both enjoy and actually put down
No zoning, no pollution, no advisers—just squares, circles, people, and time. Enlarge / Are you enticed by this kind of orderly madness with a clean graphical layout? Then I suggest you… settle in. (credit: Goblinz Studio).....»»
Researchers develop "founding document" on synthetic cell development
Cells are the fundamental units of life, forming the variety of all living things on Earth as individual cells and multicellular organisms. To better understand how cells perform the essential functions of life, scientists have begun developing synth.....»»
Research quantifies "gap" in carbon removal for first time—shows countries need more awareness, ambition and action
New research involving the University of East Anglia (UEA) suggests that countries' current plans to remove CO2 from the atmosphere will not be enough to comply with the 1.5ºC warming limit set out under the Paris Agreement......»»
Scientists advance research of harmful PFAS chemicals and their impacts
A bemused fishmonger at a seafood market in Portsmouth, N.H., weighed and packaged a dozen filets of fish and three lobster tails for his unusually exacting customers, Dartmouth researchers Celia Chen, Guarini, a research professor of biological scie.....»»
Human activity is causing toxic thallium to enter the Baltic Sea, finds new study
Human activities account for a substantial amount—anywhere from 20% to more than 60%—of toxic thallium that has entered the Baltic Sea over the past 80 years, according to new research by scientists affiliated with the Woods Hole Oceanographic In.....»»
Physicists arrange atoms in close proximity, paving way for exploring exotic states of matter
Proximity is key for many quantum phenomena, as interactions between atoms are stronger when the particles are close. In many quantum simulators, scientists arrange atoms as close together as possible to explore exotic states of matter and build new.....»»
When scientists and K-12 teachers team up, the results can be spectacular or lackluster
The results of an in-depth review of published research on scientists conducting K-12 science, technology, engineering and mathematics (STEM) outreach suggest that increased collaboration with K-12 educators could improve such projects......»»
New eco-friendly lubricant additives protect turbine equipment, waterways
Scientists at the Department of Energy's Oak Ridge National Laboratory have developed lubricant additives that protect both water turbine equipment and the surrounding environment......»»
