Phys.org / 'Rock clock' refines time measurement of Earth's early complex animal life
How can we measure time more than 500 million years into the past? A study recently published in Nature Communications by researchers at the University of Lausanne presents a new geological "rock clock" that allows major ...
Phys.org / AI model predicts chemical effects on gene expression, speeding drug discovery
Inside a diseased cell, the genes are in chaos. Some are receiving signals to overproduce a protein. Others are reducing activity to abnormal levels. Up is down and down is up. The right molecule could restore order, reversing ...
Phys.org / Experiment observes quantum radiation reaction as electrons hit an ultra-intense laser
For the first time, a quantum radiation reaction in strong electromagnetic fields has been demonstrated experimentally by allowing electrons to collide with an extremely intense and powerful laser beam. The research findings ...
Phys.org / The cactus on your desk is an evolution speed machine
The cactus on your windowsill may grow slowly, but new research shows that cacti are surprisingly fast at creating new species. Biologists have long thought that pollinators and specialized flowers drive the formation of ...
Medical Xpress / Gene mutation tied to schizophrenia slows brain's updating of beliefs
One of the symptoms of schizophrenia is difficulty incorporating new information about the world. This can lead patients to struggle with making decisions and, eventually, to lose touch with reality. MIT neuroscientists have ...
Phys.org / More and more teachers and students are using AI, even though it might do more harm than good
K-12 teachers and students across the country are increasingly using AI in and out of classrooms, whether it is teachers turning to AI to refine lesson plans or students asking AI to help them research a particular topic.
Phys.org / TESS discovers a super-Earth exoplanet orbiting nearby star
Using the Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new super-Earth exoplanet orbiting a star located about 83 light years away. The newfound alien world is slightly larger than Earth and ...
Phys.org / Ultrafast laser pulses bring diamond-based quantum internet closer to reality
The controlled generation of single photons is an essential element of numerous quantum technology applications, such as quantum networks and quantum computing. A research team has now demonstrated the successful application ...
Phys.org / Physicists trace the sun's magnetic engine, 200,000 kilometers below its surface
Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and migrate toward the ...
Medical Xpress / Usage of psychedelic psilocybin rises after state decriminalization, new study finds
Psilocybin is a naturally occurring psychedelic compound that is the active ingredient in certain types of mushrooms (also called magic mushrooms), long used by Indigenous communities in parts of Mexico and Central America ...
Phys.org / Ultrathin BiFeO₃ breaks the 30 nm limit, delivering fourfold stronger piezoelectricity
Piezoelectric materials, which convert mechanical stress into electricity and vice versa, are essential components in sensors, actuators, and energy-harvesting devices. However, the best piezoelectric materials, such as lead ...
Medical Xpress / GLP-1 medications used to treat diabetes and obesity may also help alleviate symptoms of anxiety and depression
GLP-1 medications used to treat diabetes and obesity were associated with a reduced need for hospital care and sickness absence due to psychiatric reasons, a new study shows. The large register-based study was carried out ...
