Phys.org / Cool beans, smart roots: Special cell helps seedlings survive drought battered and nutrient poor soils

Researchers have identified a previously unknown cell type hidden on the roots of common beans, a microscopic survival mechanism that could inform the development of more climate-resilient crops and reduce fertilizer dependence.

Phys.org / Cold-triggered ion channel in bacteria may point to broader temperature-sensing mechanism

All lifeforms need to continuously adapt to temperature changes to survive. Now, Weill Cornell Medicine investigators studying a bacterial protein have identified a new mechanism of sensing cold temperatures. The finding ...

Phys.org / How higher temperatures can benefit (or devastate) bumble bee populations

New research finds that higher temperatures can actually benefit some bumble bee species—particularly those that make subterranean nests. However, periods of extreme heat appear to offset those benefits, and may contribute ...

Phys.org / Even the most remote ocean is contaminated with zinc from human sources, research reveals

The vast, deserted South Pacific is considered unspoiled nature. But this ocean is not as unspoiled as we would like to think. A new study by a group of researchers from ETH Zurich and the GEOMAR Helmholtz Center for Ocean ...

Phys.org / Online echo chambers can arise even without algorithmic nudges or seeking like-minded people

A new study of online communities suggests that their interaction dynamics can amplify small, local imbalances in opinions, rapidly turning initially mixed-opinion communities into highly-polarized ones—even without the algorithms ...

Phys.org / 'Indian Niño' drove record heat in 2023 and 2024, new study finds

In 2023 and 2024, Earth's average global surface temperature spiked nearly 0.3 degrees Celsius above what was already expected from climate change. Each year was declared the hottest on record and coincided with deadly wildfires, ...

Phys.org / 'Not just hot water': Marine heat waves can create toxic relationship between seagrasses and microbes

Heat stress from marine heat waves can create a toxic relationship between seagrasses and a hidden ecosystem of bacteria, transforming a previously beneficial co-existence between marine plants and microbes into a harmful ...

Phys.org / Carbon-free ferrocene alternative opens up new possibilities for future materials

About 75 years ago, scientists accidentally synthesized a compound called ferrocene in which the iron (Fe) atom is sandwiched between two C5H5 rings—(C5H5)Fe(C5H5). This compound opened up a new era in transition metal chemistry, ...

Phys.org / Deforestation may push Amazon degradation threshold below 2°C warming

Around two-thirds of the Amazon rainforest could shift into degraded forest or savanna-like ecosystems at 1.5–1.9°C of global warming if deforestation increases to roughly 22–28% of the Amazon, according to a new study from ...

Phys.org / Freshwater mussel protein offers new source of inspiration for medical-grade glues

Researchers at the University of Toronto have identified a protein from the quagga mussel that can stick to surfaces underwater, even though it lacks a chemical feature long thought to be essential for this kind of adhesion. ...

Phys.org / The lost koala: New fossil species was hiding in plain sight for 100 years

In 2024, the Western Australian Museum received a donation. It was a koala skull collected from Moondyne Cave in Margaret River by Lindsay Hatcher, an avid caver. There was something a bit odd about this skull, and we were ...
