Phys.org / Atomic step–terrace ordering enables unprecedented precision in mechanical testing
As modern technologies shrink to the nanoscale, surfaces increasingly dictate how materials deform, yield, and fail. Yet probing this regime has long been hindered by the challenge of preparing and controlling surfaces with ...
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 / 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 / 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 / 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 / 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 / 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 ...
Phys.org / How temperature changes light: New model could guide smarter LEDs, sensors and photonic devices
Technion researchers have developed, for the first time, a comprehensive physical model explaining how the properties of a radiating material, including absorption, emission, and quantum efficiency, affect the fundamental ...
Phys.org / Ancient bacterial toolkit links human gut health to ocean carbon cycling
Our gut is colonized by legions of bacteria, which supply us with essential nutrients and support our health. Among them are Akkermansia bacteria, which might be helpful in the management of conditions like obesity and diabetes.
