Phys.org / Did NASA's Curiosity rover find signs of ancient life on Mars? An astrobiologist explains how we determine 'life'
NASA's Curiosity rover has identified seven new organic compounds on the planet Mars, according to new research published in Nature Communications.
Tech Xplore / Excuse me, is that solar panel pointing in the right direction?
On a bright morning, graduate student Jeremy Klotz and professor Shree Nayar walked through upper Manhattan with a tall tripod and a camera that takes 360-degree images. Their route took them to bike docking stations, which ...
Phys.org / A huge tectonic boundary shook the ground where dinosaurs once stood
Scientists have discovered a Jurassic tectonic plate boundary that could help to predict what the planet might look like millions of years into the future. Dr. Jordan Phethean, Senior Lecturer in Earth Sciences at the University ...
Phys.org / Bonuses can lower self-set goals and reduce performance, experiment suggests
Financial bonuses are often used to motivate employees to meet targets and boost productivity. But do they actually work? New research from Tilburg University suggests these incentives can sometimes have the opposite effect. ...
Phys.org / How cells turn mechanical forces into biochemical signals
Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. ...
Phys.org / Brazil unearths a bizarre beaked reptile with a trans-Atlantic prehistoric link
Paleontologists from the Federal University of Santa Maria (UFSM) have published a new study in the scientific journal Royal Society Open Science, in which they describe a new species based on a fossil skull approximately ...
Phys.org / Turning vibrations into value—a new catalyst converts CO₂ into useful CO
Researchers at The University of Osaka have developed a catalyst that uses vibrational energy to convert carbon dioxide (CO2) into carbon monoxide (CO), an important industrial feedstock. The work, published in the Journal ...
Medical Xpress / Genetic study reveals likely cause of common heart valve defect
New clues from genetic research may help explain what causes the most common heart defect present at birth. Researchers at KTH Royal Institute of Technology and Karolinska Institutet have identified rare DNA changes during ...
Tech Xplore / These penny-size ultrasonic tags ditch batteries and silently turn everyday objects into private smart home trackers
Most smart home devices require power one way or another. You have to plug them in, recharge them, or replace their batteries at some point. Georgia Tech researchers think they have a better way with small metal tags that ...
Medical Xpress / Dopamine deficiency found to drive memory impairment in Alzheimer's disease
Why do memories fade in Alzheimer's disease—and can they be restored? University of California, Irvine researchers have uncovered a key mechanism underlying memory loss, showing for the first time that dopamine dysfunction ...
Medical Xpress / US dentists still prescribe far more opioids for pain than peer nations
People getting their teeth pulled or drilled by dentists in the United States are still much more likely to get powerful opioid medications than dental patients in other developed countries or even the U.S. territory of Puerto ...
Medical Xpress / Impaired cell recycling leads to muscle weakness in rare genetic disorder
Myofibrillar myopathy type 6 (MFM6) is a rare genetic muscle disorder that leads to severe muscle weakness and a drastically shortened life expectancy due to a disruption in muscle protein regulation. Researchers at the University ...
