Researchers used mouse models and human post-mortem brain tissue to study the molecular underpinnings that may increase the risk of Alzheimer's after traumatic brain injury (TBI).
Fearful memories of others seen in mouse brain
Researchers have revealed that the CA1 and CA2 regions in the brain respectively encode the locations and individuals linked with a threatening experience. The results show that, beyond simply recognizing individuals, CA2 helps record more complex aspects of social memory: in this case, whether another individual is safe or risky.
New research reveals how large-scale adoption of electric vehicles can improve air quality and human health
A new study suggests that large-scale adoption of electric vehicles (EVs) could lead to significant population-level health benefits. The research team used computer simulations to show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between...
Machine learning analysis sheds light on who benefits from protected bike lanes
A new analysis leverages machine learning to help answer a thorny question: where should new protected bike lanes be placed to provide maximum benefit? The research team use machine learning and optimization to help inform such decisions. It's a challenge that required new computational approaches.
NASA, NOAA: Sun reaches maximum phase in 11-year solar cycle
Experts have announced that the Sun has reached its solar maximum period, which could continue for the next year. Scientists will not be able to determine the exact peak of this solar maximum period for many months because it's only identifiable after they've tracked a consistent decline in solar activity...
Bonobos may be more vulnerable than previously thought, suggests genetics study
Bonobos, endangered great apes that are among our closest relatives, might be more vulnerable than previously understood, finds a genetics study that reveals three distinct populations.
Tube sock-like skunk covers more ground than deer, impacted by winter weather, study finds
A study in the Cascade Range in Oregon of a tiny, elusive skunk found the animal can cover more ground than deer and is sensitive to climate change, particularly severe winter weather.
Seven new frog species discovered in Madagascar: Sounds like something from Star Trek
Researchers have discovered seven new species of tree frogs that make otherworldly calls in the rainforests of Madagascar. Their strange, high-pitched whistling calls sound more like sound effects from the sci-fi series Star Trek. As a result, the researchers have named the new species after seven of the series' most...
Scientists have successfully bred corals to improve their heat tolerance
A new study has shown that selective breeding can lead to a modest rise in coral heat tolerance. The study documents the world s first effort to selectively breed adult corals for enhanced heat tolerance, i.e. the ability of adult corals to survive intense marine heatwaves. The breeding effort was...
Let there be light: Bright future for solar panels, TV screens and more
From brighter TV screens to better medical diagnostics and more efficient solar panels, new research has discovered how to make more molecules stick to the surface of tiny nanocrystals, in a breakthrough that could lead to improvements in everyday technology.
