Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Research reveals best conditions for storing graphene oxide
A research team from Skoltech and other scientific organizations conducted a study to determine which conditions are the most suitable for storing graphene oxide—a promising material that can be used for manufacturing composite materials, gas senso.....»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»

Real-time Linux is officially part of the kernel after decades of debate
Now you can run your space laser or audio production without specialty patches. Enlarge / Cutting metal with lasers is hard, but even harder when you don't know the worst-case timings of your code. (credit: Getty Images).....»»
Research predicts rise in tropical hydraulic failure
Hydraulic failure in tropical environments is expected to increase, according to new research published in New Phytologist. As weather patterns change and temperatures rise, plants will need to adapt in order to survive. Hydraulic failure occurs when.....»»
Strange Visual Auras Could Hold the Key to Better Migraine Treatments
Research on the visual patterns that foreshadow migraines may reveal clues on how painful headaches arise from the brain even though it has no pain receptors......»»
How humans are affecting the Northern Hemisphere"s wind patterns
The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to intense droughts and heat waves in North America.....»»
Tracking plasma progression in a picosecond: Physicists develop ultra-fast laser method to study high-density plasmas
In a few picoseconds (trillionths of a second), a small, thin piece of copper momentarily becomes dense plasma, specifically a state called warm dense matter, warm being a relative term—the metal is nearly 200,000 degrees Fahrenheit. With the short.....»»
Hidden Patterns Show Nobel Prize Science Trends
Time lags between discoveries and awards show how the Nobel Prizes reward science.....»»
Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»
Scientists decipher the energy patterns in our cells
Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this relates to health outcomes—.....»»
Disappearing scientists: Attrition and retention patterns of 2.1 million scientists in 38 OECD countries
Research has been showing that women scientists continue to disappear from science at a significantly higher rate and in higher percentages than men. This is what social scientists have thought for decades—but this is no longer the case today, acco.....»»
