Study finds high prevalence of hidden brain changes in people with heart disease
A new analysis involving over 13,000 people has found changes to blood vessels in the brain that can increase the risk of stroke and dementia are common in people with a range of heart conditions, regardless of whether they have experienced a stroke.
New genetic analysis tool tracks risks tied to CRISPR edits
While CRISPR has shown immense promise as a next-generation therapeutic tool, the gene editing technology’s edits are still imperfect. Researchers have developed a new system to test and analyze CRISPR-based DNA repair and related risks from unintended…
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming. A …
Researchers find energy development and tree encroachment impact Wyoming pronghorn
While Wyoming is home to some of North America’s most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
