Phys.org / A direct leap into terahertz: Dirac materials enable efficient signal conversion at room temperature
Highspeed Internet, autonomous driving, the Internet of Things: data streams are proliferating at enormous speed. But classic radio technology is reaching its limits: the higher the data rate, the faster the signals need ...
Phys.org / Birds shift to higher mountain elevations in Europe as climate warms
Many bird species have moved toward colder areas in the mountains of Europe as the climate has warmed over the past two decades. Sunny southern slopes attract birds to live at higher elevations than do shadier northern slopes.
Phys.org / An adolescent growth spurt in young stars helps giant planets form
Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. ...
Phys.org / Spain not ruling out lab leak as cause of swine fever outbreak
Spain's government said Friday it had not ruled out an accidental laboratory leak as the cause of an outbreak of African swine fever that has rocked the country's lucrative pork industry.
Phys.org / Close brush with two hot stars millions of years ago left a mark just beyond our solar system
Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost like the scent of perfume ...
Tech Xplore / Zinc-ion batteries get a boost from protective film that reduces dendrite formation
While burning electric vehicles, exploding e-bikes and melting smartphones no longer make the headlines, the issue of battery safety has yet to be fully resolved. To address this, UBC researchers recently made a crucial breakthrough ...
Phys.org / Increasing plant diversity in agricultural grasslands boosts yields, reducing reliance on fertilizer
Higher plant diversity in agricultural grasslands increases yields with lower inputs of nitrogen fertilizer. That is the headline finding of a landmark, international study led by Trinity College Dublin that paints a promising ...
Phys.org / Ancient stalagmite provides insights into how climate affected early communities in cradle of civilization
The Fertile Crescent, a boomerang-shaped region spanning modern-day Middle Eastern countries, is considered the cradle of civilization and where farming first emerged. But little is known about how climate change influenced ...
Tech Xplore / Overparameterized neural networks: Feature learning precedes overfitting, research finds
Modern neural networks, with billions of parameters, are so overparameterized that they can "overfit" even random, structureless data. Yet when trained on datasets with structure, they learn the underlying features.
Tech Xplore / Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds
Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, ...
Phys.org / Probing the quantum nature of black holes through entropy
In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, ...
Medical Xpress / A single shot of HPV vaccine may be enough to fight cervical cancer, study finds
A single HPV vaccination appears just as effective as two doses at preventing the viral infection that causes cervical cancer, researchers reported Wednesday.
