Phys.org / Eagles known as hunting specialists reveal an unexpected taste for goat
Eagles are symbols of hunting prowess. Known as top predators wherever they live, they are often assumed to kill as their primary mode of obtaining food. However, a new study published in the Journal of Raptor Research reports ...
Phys.org / Tracks and tooth marks reveal bone-crushing dogs at Nebraska supervolcano ashfall site
Thirty-five years on—well, 12 million, technically—Ashfall Fossil Beds State Historical Park continues to offer important glimpses of prehistoric life in Nebraska.
Phys.org / Nano-antennas make living cells light up brighter and faster
Researchers at Delft University of Technology have demonstrated for the first time that nano-antennas can enhance the fluorescence of proteins in living human and other mammalian cells. Scientists already use smart fluorescent ...
Phys.org / How methylation sets a parasite in motion to invade host cells
Parasites such as Toxoplasma gondii and the malaria parasite Plasmodium falciparum depend on rapid, precisely controlled movement to complete their life cycles. To start moving, they must assemble actin filaments at their ...
Phys.org / Self-blinking 'fairy lights' allow DNA to be imaged at almost double-helix-width resolution
Researchers have developed fluorescent molecules that permit imaging of how DNA is packaged inside living cells at unprecedented resolution and, in preserved cells, at a resolution close to the width of the double helix itself.
Phys.org / Inspired by nature, scientists engineer tiny 'nitrogen factories' that could help future cereal crops
As fertilizer prices remain elevated, researchers at South Dakota State University are developing an innovative solution to corn's nitrogen supply problems by taking inspiration from an ancient Mexican variety and root nodules ...
Phys.org / Compound with the potential to treat drug-resistant HIV identified
A large international team has developed a new compound that showed strong antiviral activity against HIV, including some drug-resistant variants.
Phys.org / Low oxygen could limit insects' uphill escape from climate warming
Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...
Phys.org / Milky Way's own gravity can mimic dark matter clues, stellar stream simulations suggest
Most of the stars in our Milky Way galaxy sit neatly on a flat plane. But the space around our galaxy is much more chaotic. Rogue bands of stars called "stellar streams" orbit the Milky Way much like planets in our solar ...
Phys.org / Major polluters are worsening the Western US water crisis: A new way to measure who's responsible
Climate change was once something scientists warned us about, and now it's a reality we are living in. In California's Central Valley, about one-third of climate-related groundwater loss between 2003 and 2024 can be attributed ...
Phys.org / Deep underground, SuperCDMS begins hunting light dark matter with 24 cryogenic crystals
In the hunt for one of nature's most elusive substances—dark matter, which makes up 85% of all matter in the universe—scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic ...
Phys.org / Ancient DNA reveals cacao was consumed in present-day Georgia 1,000 years ago
One of the world's favorite sweet treats, chocolate, may have been enjoyed in eastern North America much earlier than previously thought, about 1,000 years ago. New research published in the journal PLOS One suggests that ...
