An ischemic stroke is a type of stroke that occurs when a blood clot in an artery, also known as thrombus, or the progressive narrowing of arteries, blocks the blood and oxygen flowing to the brain. This process can cause both temporary and permanent brain damage, for instance, leading to partial paralysis, cognitive impairments and other debilitating impairments.

Statistics suggest that older age increases the risk of experiencing ischemic strokes...

The past century of human-induced warming has increased rainfall variability over 75% of the Earth’s land area—particularly over Australia, Europe and eastern North America, new research shows.

The findings, by Chinese researchers and the UK Met Office, were published in the journal Science. They provide the first systematic observational evidence that climate change is making global rainfall patterns more volatile.

Climate models had predicted this variability would worsen under climate change. But these new findings show rainfall variability has already worsened over the past 100 years—especially in Australia.

Past studies of the observational record either focused on long-term average rain, which is not systematically changing globally...

New insights into the prevalence and mechanisms of gene misexpression in a healthy population could help in diagnosing and developing treatments for complex diseases.

Scientists have uncovered that ‘gene misbehaviour’ – where genes are active when they were expected to be switched off – is a surprisingly common phenomenon in the healthy human population.

The team also identify several mechanisms behind these gene activity errors. This may help inform precision medicine approaches and enable the development of targeted therapies to correct expression.

Researchers from the Wellcome Sanger Institute, the Univer...

A research team at Rice University led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.

The team has pioneered a new method to extract purified active materials from battery waste as detailed in the journal Nature Communications on July 24. Their findings have the potential to facilitate the effective separation and recycling of valuable battery materials at a minimal fee, contributing to a greener production of electric vehicles (EVs).

“With the surge in battery use, particularly in EVs, the need for developing sustainable recycling methods is pressing,” Tour said.
