A new study reveals how the duplication of the salivary amylase gene may not only have helped shape human adaptation to starchy foods, but may have occurred as far back as more than 800,000 years ago, long before the advent of farming.
New method for measuring luminescence lifetime offers breakthrough in scientific imaging
Researchers introduce an innovative approach to image luminescence lifetimes. This simple approach uses readily-available cost-effective equipment, paving the way for advanced studies of chemical dynamics in environmental and biological systems. For example, it allows to record oxygen dynamics with much higher temporal and spatial precision.
Forever Chemicals found in bottled and tap water from around the world
Scientists have discovered toxic 'Forever Chemicals' present in samples of drinking water from around the world.
Invention quickly detects earliest sign of heart attack
With heart attacks, every second counts. A new blood test diagnoses them in minutes rather than hours and could be adapted as a tool for first responders and people at home.
Study explores how traumatic brain injury (TBI) may be linked to Alzheimer’s disease
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.
