Phys.org / Animal-bone records reveal how cattle and sheep fueled medieval England's changing economy
As populations expanded in medieval England, key changes occurred in the uses of cattle and sheep to produce food and materials, according to a study published Sept. 2, 2026, in the journal PLOS One by Matilda Holmes of the ...
Phys.org / Young sunlike system reveals comets may carry water toward forming planets
Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star similar to our sun. The observations point to a possible mechanism for how water might be transported ...
Phys.org / New nanostructure makes non-linear light conversion 72,000 times more efficient
Researchers from Graz University of Technology (TU Graz), Harvard and the University of Texas at Austin (UT Austin) have developed an innovative method for coupling light non-linearly. This opens up new possibilities for ...
Phys.org / How cells teach themselves to move together
Scientists have long wondered how cells organized into sheets begin to move together to form organs, especially when the sheets form closed, sphere-like surfaces and tissues with no edges to direct motion. Researchers at ...
Phys.org / Exotic pines in the Southern Hemisphere grow faster and are more drought-resistant, study reveals
A new study published in the journal Nature reveals that conifers planted outside their native range in the Southern Hemisphere not only grow up to four times faster than those in the Northern Hemisphere but also show greater ...
Phys.org / Chemists design extra-sticky adhesives that degrade on command
A good adhesive is unequivocally sticky. A great adhesive is sticky until you don't want it to be sticky anymore—a label on cardboard until it's time to recycle it. Medical tape on a cut until the wound heals. A GWAR poster ...
Phys.org / Tracking emperor penguins from space
For the first time, geographers from Durham University have used freely available satellite radar images to track emperor penguins through the polar winter—giving a year-round view of their movements. Monitoring the endangered ...
Phys.org / Electric fish keep from blinding themselves with these brain cells
The brain cells you see in the above image help an African fish decode electric signals to spot prey, scan its murky surroundings and communicate with its fellows. By rigorously mapping how these cells in the electrosensory ...
Phys.org / Bio-based plastic turns into fertilizer after use
Plastic waste is one of the world's fastest-growing environmental problems. According to the Organization for Economic Co-operation and Development's Global Plastics Outlook: Policy Scenarios to 2060 report, global plastic ...
Phys.org / Why lower-class workers are less likely to negotiate for higher pay—and how it could cost some nearly $800,000
Michele Gelfand has studied and taught negotiation for years. A professor of organizational behavior at Stanford Graduate School of Business, she sees negotiation as a skill that is imperative for everyone to learn. "It's ...
Phys.org / Seven new species show 250-million-year-old marine group is still evolving
Scientists believed there were only two species of hornerid bryozoans in Aotearoa New Zealand, but new research shows several more have been secretly evolving and thriving in the nation's southern waters.
Phys.org / Blue Origin's New Glenn explosion shows infrasound can detect rocket accidents from up to 1,700 kilometers away
When Blue Origin's New Glenn launch vehicle accidentally exploded during a static test fire in May 2026, the explosion generated low frequency soundwaves below the range of human hearing.
