Phys.org / This tiny grain-of-rice sensor gives robots a new sense and changes what delicate tools can detect
Researchers have developed a sensor about the size of a grain of rice that can measure forces and twisting motions in all directions using light instead of traditional electronics. The new sensor could help robotic tools ...
Phys.org / Northern Sri Lanka's oldest confirmed settlement reshapes what archaeologists thought about early island life
A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation ...
Phys.org / The moon's largest impact crater scattered something priceless—and Artemis may be heading straight into it
A new study, published in Science Advances, has refined some important details about the moon's largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of the moon. The new details ...
Phys.org / Old bottles and battery acid can drive production of valuable industrial chemicals
Battery acid from old cars, with a little help from a catalyst, can give plastic waste a new purpose, using it to drive the production of useful chemicals, powered by sunlight alone. A recent study by researchers at the University ...
Phys.org / Dinosaur dental fossils reveal bird-like parental care bonds
Baby dinosaurs were likely fed more nutritious food than their adult counterparts, a finding that could offer insights into their social evolution, suggests a new study. Paleontologists uncovered this finding by studying ...
Phys.org / The first direct observation of laser-created isolated hopfions
Over the past few decades, some physicists worldwide have been investigating unusual particle-like magnetic structures known as topological solitons. These structures could potentially be leveraged to develop new cutting-edge ...
Phys.org / TikTok algorithm showed a pro-Republican bias during the last US presidential election
TikTok's algorithm did not treat Democrats and Republicans equally during the 2024 US presidential election. According to a paper published in Nature, its recommendation system showed a Republican-leaning skew in three states. ...
Phys.org / Spiral galaxy's brilliant heart shines bright in a new picture from NASA's Webb telescope
A spiral galaxy's brilliant heart outshines everything within sight in a new picture from NASA's Webb Space Telescope.
Phys.org / From flying discs to glowing orbs, these newly opened Pentagon files point somewhere stranger than expected
The Pentagon on Friday released a first batch of secret files documenting reported sightings of unidentified flying objects—some dating back to the 1940s—fanning speculation over whether alien life exists.
Phys.org / Antarctica sea ice collapse driven by triple whammy of climate chaos, scientists find
Antarctica is being ravaged by a triple-whammy of climate chaos that has melted sea ice to record lows, a new study has revealed. For decades, the frozen wilderness at the bottom of the world defied global warming trends, ...
Phys.org / Scientists split gentoo penguins into four species, one totally new to science
The four-foot-tall Emperor penguin of Antarctica may be the most iconic member of this unique family of birds, but 17 other species of penguins populate the Southern Hemisphere, many of them confined to isolated islands that ...
Phys.org / Anion swap unlocks sevenfold CO₂ capture in polyionic liquids
A joint research team from Nitto Boseki Co., Ltd. (Nittobo) and Tohoku University has revealed that polyionic liquids (PILs) can achieve high carbon dioxide (CO₂) adsorption when their counter anions are exchanged. This discovery ...
