Unexpected pathway turns water and CO₂ into climate‑neutral methane on nickel–zirconia

Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible to synthesize natural gas, or methane (CH4), using CO2

Scientists may have finally found how Alzheimer's spreads through the brain

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow

Loss of DNA protector gene exposes vulnerabilities in cancerous cells

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.

Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure

Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. Niclas Lundsgaard of The University of Queensland (UQ), Aus

Brown leaves before fall could signal lasting heat damage, researchers warn

Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water transport or whether browning leaves are a consequence o

Bottlenose dolphins in the Adriatic Sea seem to be heavily reliant on trawlers for food

Bottlenose dolphins in the Adriatic Sea are spending much of their time following trawlers to scavenge for food, scientists say. The Adriatic seabed has been plowed by bottom trawlers for decades, resulting in ecosystem damage. Many apex predators are no longer present there. Onl

A benchmark for how different disturbances influence the loss and recovery of carbon and C

Tropical moist forests account for 70% of global living biomass. Deforestation and degradation—that is, the partial damage to tree stands—as well as the subsequent regeneration of forests therefore play a pivotal role in the global carbon cycle. While the effects of large-scale t

Scientists discover why some brains resist Alzheimer's

Some brains appear to fight back against Alzheimer's by helping immature brain cells survive damage instead of succumbing to it. Understanding this natural resilience could point researchers toward entirely new ways to protect memory and slow dementia.

Drinking to cope with stress may permanently rewire your brain

Using alcohol to cope with stress when young may permanently alter the brain, making it harder to adapt to challenges and increasing the risk of returning to drinking later in life. Researchers also found signs of brain damage associated with early dementia, suggesting the effect

'Major' damage as super typhoon hits US islands

A "super typhoon" with the force of a Category 5 hurricane tore through the U.S. Pacific territories of the Northern Marianas and Guam on Monday, with authorities saying they had received reports of "major" damage on the small island of Rota.

Wasted pumpkin peel can keep your food fresh

Researchers at Kyushu University have developed a new food preservation solution. Using pumpkin peel as a raw material, they synthesized a nanomaterial for food packaging that slows the deterioration of fruit and other produce while reducing transport damage. The findings were pu

New research finds connection to place predicts hurricane response among US coastal reside

For U.S. coastal residents, storm surge is among the deadliest hurricane hazards, causing catastrophic property damage and loss of life, and scientists expect tropical storms to grow more intense. During Hurricane Ian in 2022, storm surge accounted for 41 of the 66 direct deaths.
