Phys.org / Gravitational waves from colliding black holes may allow detection of dark matter
Dark matter is thought to make up most of the matter in the universe, but the only way it interacts with its surroundings is through gravity. If two colliding black holes spiral through a dense region of dark matter and merge, ...
Phys.org / Gravitational wave detectors can now 'autotune' signals to harmonize the heavens
Gravitational wave researchers working on the world's most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.
Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice
Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...
Phys.org / Why are some people mosquito magnets? Clues are emerging
Ever felt like mosquitoes bite you while ignoring everyone else? Scientists are now making progress in deciphering the complex chemical cocktail that makes particular people more enticing to these disease-spreading bloodsuckers.
Phys.org / Meet the whistling mice that use inflatable air sacs to sing
Mice do more than just squeak when they want to make a noise. They can also sing. And the way they do it is different from most mammals that produce sounds by vibrating their vocal cords. When Alston's singing mouse (Scotinomys ...
Phys.org / Bright blazar reveals 433-day optical quasi-periodic oscillation across nine years
By analyzing the data from the Whole Earth Blazar Telescope (WEBT), an international team of astronomers has discovered optical quasi-periodic oscillation (QPO) in a bright quasar known as 3C 454.3. It is so far one of the ...
Phys.org / Work songs can improve team coordination, study finds
Work songs, musical pieces designed to be performed or sung while working, have been widely documented across various cultures and in different historical periods. For instance, people in different nations have been known ...
Phys.org / Largest-ever survey of physicists puts Standard Model of cosmology under scrutiny
The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of physics's most important questions, from the nature of black holes and dark matter, to the still-incomplete ...
Phys.org / Atoms vibrate on circular paths—with an unexpected twist
An international team of researchers, including scientists from HZDR and Fritz Haber Institute of the Max Planck Society, for the first time directly observed how angular momentum is transferred and conserved within a crystal ...
Phys.org / Human childbirth is not uniquely difficult among mammals
Human childbirth is commonly viewed as uniquely difficult and dangerous. The reason: The combination of bipedalism and large brains creates a tight fit between the baby and the birth canal. Research at the University of Vienna ...
Phys.org / Wine's leftovers could help wean chicken farms off antibiotics
Every year, millions of gallons of wine are pressed, leaving behind a mountain of pulpy residue—grape skins, seeds, stems and peels—that wineries struggle to dispose of. Now, researchers say this overlooked byproduct could ...
Phys.org / A baby bird's wish list: Mild weather, attentive parents, not being the smallest sibling
Experiences in the first days and weeks of life can have a profound impact on humans—and birds. A new study led by Sage Madden, a graduate student in evolution and ecology at the University of California, Davis, shows how ...
