Phys.org / Ancient climate records reveal a wetter Levant that may have guided early humans out of Africa
For modern residents of the Levant, the "Red Sea Trough" usually brings a brief, dusty transition between seasons. But 127,000 years ago, this same weather pattern may have been the literal key to human history. A new study, ...
Phys.org / Scientists create a new state of matter at room temperature using light and nanostructures
Researchers at Rensselaer Polytechnic Institute (RPI) have created a new and unusual state of matter—known as a supersolid—by engineering how light and matter interact inside a nanoscale device. The work, published in ...
Phys.org / High-resolution atlas shows how thirsty plants hold out during drought
The United States and Mexico have been in a historic megadrought since the turn of the century. For more than 25 years, the American Southwest has faced the severe social and economic consequences of this megadrought—including ...
Phys.org / Using cow dung for sustainable carbon dioxide capture
Climate change is one of the most pressing global challenges in the present times. Increasing carbon dioxide (CO2) concentrations in the atmosphere are a major factor contributing to this phenomenon. Activities such as the ...
Phys.org / Plastic bottles transformed into Parkinson's drug using bacteria
A drug to treat Parkinson's disease can be made from waste plastic bottles using a pioneering method, a study shows. The approach harnesses the power of bacteria to transform post-consumer plastic into L-DOPA, a frontline ...
Phys.org / Ice satellite detects powerful geomagnetic storm with precision
It seems improbable that a satellite designed to monitor polar ice sheets and floating sea ice could accurately measure a disturbance in Earth's magnetic field. But that is just what ESA's CryoSat mission did earlier this ...
Medical Xpress / Psilocybin combined with psychotherapy shows significant efficacy in treatment-resistant depression
There is an urgent need for new and more effective treatments for depression. The results of a recent study show that psilocybin, an active compound found in certain mushrooms, can have a significant antidepressant effect. ...
Phys.org / Global insect rescue plan requires new technology to ensure success
Cameras that photograph insects overnight and AI that identifies them are among a new generation of tools that could finally allow scientists to track whether the world's plan to save nature is working for its most overlooked ...
Medical Xpress / I'm a kidney surgeon: Here's why I hope I never see you
As a urological surgeon, I meet many patients with chronic (long-term) kidney disease. Sometimes, I see patients that have progressed to the point where their kidneys do not work at all. This leads to the toxic build-up of ...
Medical Xpress / Direct nervous system link promises more natural leg prostheses
A research team led by researchers at Chalmers University of Technology in Sweden, has, for the first time, successfully decoded leg movements directly from the remaining nerves in people with above-knee amputations. Using ...
Phys.org / New study shows democracy has deep global roots—not just Greece and Rome
A new study on ancient societies from around the world is rewriting what we thought we knew about democracy. A team of researchers analyzed archaeological and historical evidence from 31 ancient societies across Europe, Asia, ...
Medical Xpress / Study offers single explanation for two major symptoms of schizophrenia
Scientists have long known that dopamine helps the brain learn from rewards, but a new computational model shows how for people with schizophrenia this learning system can break down and simultaneously produce two very different ...
