Phys.org / How birds are spreading plastic pollution
Hungry gulls do not only steal our chips and sandwiches. They learn our habits, and look for reliable sources of food. That includes waste treatment centers, landfill or anywhere food waste is concentrated. Many gull populations ...
Phys.org / All 5 fundamental units of life's genetic code were just discovered in an asteroid sample
A new study reveals all five fundamental nucleobases—the molecular "letters" of life—have been detected in samples from the asteroid Ryugu.
Medical Xpress / How groups of neurons support the formation of memories
Neuroscientists and psychologists have been trying to understand how the human brain supports learning and the encoding of memories for over a century. Past studies suggest that memories are stored by groups of brain cells ...
Phys.org / Altered colony chemistry reveals a process that destroys termite societies
Several insect species, including ants, honeybees and termites, live in highly organized societies, also known as social insect colonies. Insects living in these colonies can take on different roles, such as reproducing, ...
Phys.org / How young galaxies grew magnetic fields faster than expected
How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter timescales. In a study published ...
Phys.org / How birds send heat into space measured for the first time—a hidden reflectance of feathers
As human-caused climate change continues to raise temperatures across the globe, understanding how birds regulate their temperature is vital for their conservation. But how much heat birds emit—an invisible spectrum of ...
Phys.org / Moons orbiting wandering exoplanets could be habitable—with one catch
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
Phys.org / Are humans naturally violent? New research challenges long-held assumptions
New research from the University of Lincoln, UK, is challenging a common assumption about the evolutionary origins of human violence, suggesting that everyday aggression does not inevitably lead to lethal conflict. The study, ...
Phys.org / What 'Project Hail Mary' gets right—and wrong—about astrophysics
"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning ...
Phys.org / China's earliest Bronze Age meteoritic iron artifact unearthed at Sanxingdui sacrificial site
In a study published in Archaeological Research in Asia, Dr. Haichao Li and a team of researchers analyzed the earliest Bronze Age meteoritic iron artifact from southwestern China, the largest found to date in the country. ...
Phys.org / A Hall 'rectenna' can detect signals over a 100 GHz frequency range
Many current wireless communication, imaging and sensing technologies rely on components that convert oscillating electric and magnetic fields (i.e., electromagnetic waves) into electrical signals. Some of the most used components ...
Phys.org / Hawaii tests asphalt made with recycled plastics and fishing nets for shedding
Hawaii has a plastic problem. The island state faces economic and logistical challenges in recycling plastic waste, including marine debris that lingers in its ocean waters. Researchers in Hawaii are pioneering a method to ...
