Phys.org / Scientists recover the oldest wooden tools from a site in Greece
Two artifacts found at a lake shore in Greece are the oldest wooden tools to be uncovered so far and date back 430,000 years.
Phys.org / From fleeting to stable: Scientists uncover recipe for new carbon dioxide-based energetic materials
When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday conditions. These configurations are often fleeting: when the pressure is released, the atoms typically ...
Medical Xpress / Being a night owl may increase your heart risk, research suggests
Middle-aged and older adults who were more active in the evenings had poorer cardiovascular health compared to their peers who were more active during the day. This may be especially true among women, according to new research ...
Phys.org / Artificial nighttime lighting is suppressing moth activity, new research shows
Moths move significantly less when exposed to artificial nighttime light, new research shows. Moths' attraction to artificial light, such as streetlights, is common knowledge and has been much studied. But, as many people ...
Tech Xplore / Low-cost system turns smartphones into emergency radiation detectors
Prompt, individual-based dose assessment is essential to protect people from the negative consequences of radiation exposure after large-scale nuclear or radiological incidents. However, traditional dosimetry methods often ...
Medical Xpress / Scientists develop first gene-editing treatment for skin conditions
Gene-editing tools like CRISPR have unlocked new treatments for previously uncurable diseases. Now, researchers at the University of British Columbia are extending those possibilities to the skin for the first time. The UBC ...
Phys.org / Collaboration of elementary particles: How teamwork among photon pairs overcomes quantum errors
Some things are easier to achieve if you're not alone. As researchers from the University of Rostock, Germany have shown, this very human insight also applies to the most fundamental building blocks of nature.
Medical Xpress / Scientists identify a brain region that differs between males and females and may influence social behavior
Scientists have uncovered a previously unknown cluster of brain cells that may help explain differences in social behavior between males and females. The small neural circuit appears to function like an on/off switch, showing ...
Phys.org / Cells' built-in capacity limit for copying DNA could impact cancer treatment
For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a cell divides, which happens constantly. Without this process, we would die. These essential, ongoing ...
Medical Xpress / The neuroscience of practice: How birds master singing
A baby's babbling may sound like nonsense, but it's actually an extended act of trial-and-error learning. As babies produce different sounds, their brains note which attempts succeed and which ones fail. Over time, that feedback ...
Phys.org / Aerial lidar mapping can reveal archaeological sites while overlooking Indigenous peoples and their knowledge
Picture an aircraft streaking across the sky at hundreds of miles per hour, unleashing millions of laser pulses into a dense tropical forest. The objective: map thousands of square miles, including the ground beneath the ...
Phys.org / World not ready for rise in extreme heat, scientists say
Nearly 3.8 billion people could face extreme heat by 2050 and while tropical countries will bear the brunt cooler regions will also need to adapt, scientists said Monday.
