Phys.org / Hormone-disrupting chemicals found in range of natural and drinking water sources
A new study has found that chemicals that can affect fertility and reproductive health are contaminating natural and drinking water supplies. The researchers involved in the study have also developed a tool to help detect ...
Phys.org / Astrophysicists use wave simulations to open a new window on dark matter
Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to testing how ultralight, or "fuzzy," dark ...
Phys.org / How evolution shaped the human skeleton: Clues from cartilage
Human and chimpanzee genomes are more than 98% identical, and the genes themselves barely differ. The changes that make us human are thought to hide instead in the DNA that controls when and where genes switch on.
Phys.org / Roaming black holes may tell the hidden history of galaxies
If you want to understand the origins of black holes, Yale astronomers say, you need to look beyond the centers of galaxies and start searching in the nooks and crannies. That's where you'll find the "wanderers"—black holes ...
Phys.org / Bat genomes and fossils point to a European origin 65 million years ago
New research from the University of St Andrews has created the largest combined study of bat genomes and fossils ever undertaken, finding that bats most likely originated in Europe around 65 million years ago before spreading ...
Phys.org / Biologists battle over North America's largest crayfish
When Caitlin Bloomer wrestled the massive Crawzilla crawdad—yes, that's its actual common name—out of the muck during a biological survey in Kentucky, she was convinced it was the largest crayfish ever recorded.
Phys.org / Earth may have gained optimal conditions for life's chemistry 4.33 billion years ago
Conditions on early Earth may have become stable enough to sustain the chemistry associated with the origins of life around 4.33 billion years ago, according to new research co-led by Planetary Science Institute senior scientist ...
Phys.org / Adding limestone to Mississippi River Basin farmlands acts as a major carbon sink, study finds
In a discovery as broad and far-reaching as the Big Muddy itself, a new Yale–led study says farmers in the Mississippi River Basin are storing more carbon dioxide (CO2) in the soil than they emit when they add limestone to ...
Phys.org / DIY filter systems improve air quality in classrooms
As students return to school and cold and flu season begins, researchers are studying ways to improve indoor air quality and reduce the risk of airborne disease transmission.
Phys.org / Hairy feet, red eyes: Salish Sea reveals two sea spider species new to science
If you're swimming in the Salish Sea late at night and feel a skittering along your calves, tiny hairy feet tip-tapping their way higher and higher toward your face, don't worry—it's probably just the stuff of nightmares: ...
Phys.org / Can this biotech innovation halt the destructive march of a cereal killer?
A UK-led research collaboration has taken a significant step in the global effort to protect cereal crops from the devastating blast fungus. Researchers at the John Innes Centre explored a recently discovered class of plant ...
Phys.org / Silicon solar cells could cut satellite power costs by up to 90%
Switching to modern silicon solar cells could cut the cost of powering satellites by as much as 90% based on beginning-of-life (BOL) performance, according to a review led by the University of Surrey. The switch to silicon ...
