Phys.org / Chip-sized optical amplifier can intensify light 100-fold with minimal energy
Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists recently found a way to make ...
Phys.org / Great white sharks grow a whole new kind of tooth for slicing bone as they age
A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialized for stealth, speed ...
Phys.org / Essential oils may provide a natural remedy for antibiotic resistance
Thyme, rosemary, and lavender have long been associated with natural medicine. Today, however, these aromatic plants are increasingly being studied by researchers. "In an era of ever-increasing microbial resistance to antibiotics, ...
Phys.org / Overlooked threat: Dams trigger temperature-driven disease in iconic salmonid fish
A new study published in Communications Biology reveals a critical, yet previously overlooked, environmental consequence of man-made dams constructed across rivers and streams. By investigating a key indicator species of ...
Phys.org / Massive runaway stars in the Milky Way: Observational study explores origins and ejection process
Researchers from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), in collaboration with the Institute of Astrophysics of the Canary Islands (IAC), ...
Phys.org / Small-scale farmers produce more of the rich world's food than previously thought
Who grows our food? This seemingly simple question is getting harder to answer in a world where our food crosses borders to get to our plate.
Phys.org / Rare fossils reveal 91 new species that survived ancient mass extinction
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday.
Phys.org / Pesticides significantly affect soil life and biodiversity, study finds
Seventy percent of soils in Europe are contaminated with pesticides. A Europe-wide study co-led by researchers of the University of Zurich now shows that their effects on soil life are substantial, as pesticides suppress ...
Phys.org / Hearing angry or happy human voices is linked to changes in dogs' balance
In a small study, dogs experienced both stabilization and destabilization of their balance upon hearing angry or happy human voices, but angry voices were linked to the biggest destabilizing effects. Nadja Affenzeller and ...
Phys.org / Laser beam flips a ferromagnet's polarity without heating the material
Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create adaptable electronic circuits ...
Phys.org / Novel 'XFELO' laser system produces razor-sharp X-ray light
A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the process, much like happens ...
Phys.org / How a superionic state enables long-term water storage in Earth's interior
The cycling of water within Earth's interior regulates plate tectonics, volcanism, ocean volume, and climate stability, making it central to the planet's long-term evolution and habitability and a key scientific question. ...
