ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study
Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established as essential signaling molecules in various organisms, t
Camera traps reveal the true culprit behind crop damage in Honduras
A new study from the Honduran Mosquitia shows how simple, noninvasive technology can help solve one of the most common challenges in wildlife conservation: identifying the species actually responsible for crop damage. The full detailed results have been published in Neotropical B
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.
