Phys.org / Nature might have a universal rhythm
Animal communication can look wildly different—flashing lights, chirping calls, croaking songs and elaborate dances. But new research from Northwestern University suggests many of these signals share a surprising feature: ...
Phys.org / Two bacteria join forces to turn chemical signals into electricity, opening up low-cost sensing options
Bacterial sensors usually rely on emitting light to transfer information about what they're sensing, but that method isn't practical in many settings. That's why most information transmission is done via electricity. And ...
Phys.org / Machine learning detects more than 60,000 earthquakes during 2025 Santorini sequence
The seismic crisis that gripped the Greek island of Santorini and its neighbors in 2025 contained more than 60,000 earthquakes, according to a unique machine learning study that identified the earthquakes as they occurred ...
Phys.org / Iron plus UV light turns alcohol into hydrogen with catalyst-like efficiency
Publishing in Communications Chemistry, researchers from Kyushu University have discovered a simple method of generating hydrogen gas by mixing methanol, sodium hydroxide, and iron ions, then irradiating the solution with ...
Phys.org / Methane emerges from interstellar comet 3I/ATLAS as it exits the solar system
Interstellar comet 3I/ATLAS is now on its way out of our solar system, never to return. The comet was only the third-ever detected object to originate from outside our solar system. Traveling at high speeds, it looped around ...
Medical Xpress / Osteopenia: Loss of bone mineral density affects millions of people. Here's what you need to know
Around 40% of adults worldwide are affected by osteopenia: a loss of bone mineral density. This condition is extremely common, particularly in postmenopausal women and elderly adults. It's estimated that more than 500,000 ...
Phys.org / Want to restore oyster reefs? Find a site where they don't wash away or become buried under the sand
Restoring once abundant oyster reefs in temperate marginal seas such as the North Sea is a challenging task. New research by NIOZ marine ecologist Zhiyuan Zhao and colleagues shows that it is necessary to consider the short-term ...
Phys.org / Nanobody repairs misfolded CFTR inside cells, boosting function in cystic fibrosis
A tiny antibody component could fundamentally transform the treatment of cystic fibrosis: For the first time, researchers have succeeded in developing a so-called nanobody that penetrates directly into human cells and can ...
Phys.org / Blended satellite data reveal what drove methane's 2019–2024 rise worldwide
Because methane has around 80 times the warming potential of CO2 over a 20-year period, it has been a major focus for climate action groups. The Global Methane Pledge, launched at COP26 in November 2021, aims to cut human-caused ...
Phys.org / Salty drinking water could be increasing your blood pressure. People living in coastal areas are most at risk
When people consider what causes high blood pressure, they often think of lifestyle factors, such as eating salty foods, lack of exercise or smoking. However, an unexpected source of salt might also be raising blood pressure ...
Phys.org / Warmer streams may be draining river food webs by sending more carbon into the air
Rising stream temperatures may be weakening the foundation of river food webs by altering how carbon moves through these watery ecosystems. In a new study published in the journal Ecosphere, researchers from Northern Arizona ...
Phys.org / Saving coral reefs will require ruthless selection over generations to beat future heat waves
Assisted evolution could help corals survive future heat waves, but careful trait choice and strong repeated selection will be needed for it to be effective. As global temperatures rise, marine heat waves are becoming more ...
