Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.
Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years – Aniakchak II. In the process, they narrowed down potential dates for the Thera volcano eruption.
To understand the unique experience of Black loss, grief and bereavement, it's necessary to consider the collective grief Black Americans have suffered as the result of America's long history of racialization and racist violence, UArizona researchers say.
Ponds, lakes, rivers and streams cover only a tiny fraction of Earth's surface, yet they are home to a comparatively large number of different species, according to a study led by University of Arizona ecologists. The findings have implications for conservation efforts around the globe.
Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much sleep associated with poorer cognitive performance and mental health, say researchers from the University of Cambridge and Fudan University.
Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say a team of scientists from the University of Cambridge and Imperial College London.
It’s often said that a little stress can be good for you. Now scientists have shown that the same may be true for cells, uncovering a newly-discovered mechanism that might help prevent the build-up of tangles of proteins commonly seen in dementia.
Ultra-powerful 7T MRI scanners could be used to help identify those patients with Parkinson’s disease and similar conditions most likely to benefit from new treatments for previously-untreatable symptoms, say scientists.
A study of ancient faeces uncovered at a settlement thought to have housed builders of the famous stone monument suggests that parasites got consumed via badly-cooked cow offal during epic winter feasts.
Watching too much TV is associated with increased risk of coronary heart disease regardless of an individual’s genetic makeup, say a team of scientists at the University of Cambridge and the University of Hong Kong.
Autistic individuals are more likely to have chronic mental and physical health conditions, suggests new research from the University of Cambridge. Autistic individuals also report lower quality healthcare than others.
Researchers have shown that aggregation of amyloid-beta, one of two key proteins implicated in Alzheimer’s disease, causes cells to overheat and ‘fry like eggs.’
Social isolation is linked to lower brain volume in areas related to cognition and a higher risk of dementia, according to research published today in Neurology. The study found that social isolation was linked to a 26% increased risk of dementia, separately from risk factors like depression and loneliness.
Scientists have released the first real-world data from Africa on the effectiveness of two doses of AstraZeneca/ChaAd0x-1 COVID-19 vaccination, showing that while protective against SARS-CoV-2, immunity against the Delta and Omicron variants was lower, even in the context of prior infection or infection after vaccination.
A graduate student from the Department of Physics and Astronomy at The University of Alabama in Huntsville (UAH) made a remarkable discovery.
In what is possibly the first direct evidence of a planet forming during an "intense and violent" breakup of a disk of swirling gas and dust, a nascent gas giant was spotted a long distance from its host star.
UArizona researchers were leaders in a worldwide effort to understand tropical trees and their futures under climate change.
