Phys.org / Arctic cyclone clusters batter sea ice, leaving coasts more exposed to storms
In the Arctic, weather plays a key role in determining how much ice covers the ocean. Arctic cyclones are one weather phenomenon with a significant influence, causing unusually warm and stormy conditions that typically lead ...
Phys.org / Oxytocin nudges distrustful men to invest 15% more in anonymous trust game
In 2005, a research team led by University of Zurich economics professor Ernst Fehr published a study in the journal Nature that provided evidence for the first time that intranasally administered oxytocin can increase trusting ...
Phys.org / Bumblebees can learn to associate new smells with their queen
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For ...
Phys.org / New hurricane graphic helps people identify watch areas, doesn't change risk perception
Hurricane warnings are only effective if people understand them. A new study by Florida State University faculty members in the School of Communication in the College of Communication and Information and the Department of ...
Phys.org / Mathematical model shows how birds create a synchronized dawn chorus
Every morning, groups of birds start singing and chirping around the same time, typically when the sun starts rising. While zoologists have been studying this collective bird behavior, called the dawn chorus, for decades, ...
Phys.org / Genome study reveals centromeres as one of the fastest-changing regions in human DNA
A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite their essential role, ...
Phys.org / Historical DNA reveals largetooth sawfish have lost much of their genetic diversity
The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past century and a half, according to a study published in the Proceedings of the Royal Society B: Biological ...
Phys.org / First evidence of Neanderthal bone tool use in Romania discovered
Deep in the Vârghiș Gorges, tucked away in the dark recesses of a cave, researchers have found the first evidence that Neanderthals used bone tools in Romania.
Phys.org / Many US public parks sit surprisingly close to hazardous waste sites and facilities that release toxic chemicals
While parks, playgrounds and hiking trails are generally thought of as "healthy" spaces, researchers from the University of Michigan have found that many of them overlap with old toxic waste sites or sit dangerously close ...
Phys.org / Late Paleozoic Ice Age warming event hints at potential climate 'tipping point'
Researchers say a spike in temperatures during an ice age 304 million years ago could inform what climate scientists are learning about rapidly changing conditions today.
Phys.org / Want a happier marriage? Study suggests one simple habit
Research has long shown that exercise benefits both physical and mental health. Now, a new study from researchers at BYU suggests that it may also strengthen marriages, especially when couples exercise together.
Phys.org / New CERN measurement challenges conventional models of how gluons behave inside atomic nuclei
A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished.
