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 / Tiny, knotted robots jump, fly and plant seeds
When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...
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 ...
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 ...
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 ...
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 / Crab shell by-products could help regulate the marine lifetime of biodegradable plastics
Biodegradable plastics hold potential for reducing marine plastic pollution, but degrade too quickly, limiting their practical use. Researchers from Gunma University now show that crab shell by-products can reduce the breakdown ...
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 ...
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 ...
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 / North African-linked stone tools reached Iberia 700,000 years ago, evidence suggests
Members of the Atapuerca Research Team from the Institut Català de Paleoecologia Humana i Evolució Social (IPHES), the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), the University of Burgos, and the ...
Phys.org / Water simulation of famous quantum effect reveals unexpected wave patterns
In the quirky quantum world, particles can be affected by forces that they never directly encounter. A classic example is the Aharonov–Bohm (AB) effect, where electrons are affected by a magnetic field, despite not passing ...
