Pangenome unlocks potential of barley's closest wild relative

Wild plants can contribute valuable genes to their domesticated relatives. Fertility barriers and a lack of genomic resources have hindered the effective use of crop-wild introgressions. An international research team led ...

Study analyzes 400 million years of enzyme evolution

Enzymes catalyze chemical reactions in organisms—without which life would not be possible. Leveraging AlphaFold2 artificial intelligence, researchers at Charité—Universitätsmedizin Berlin have now succeeded in analyzing ...

Large-scale DNA study maps 37,000 years of disease history

A research team led by Eske Willerslev, professor at the University of Copenhagen and the University of Cambridge, has recovered ancient DNA from 214 known human pathogens in prehistoric humans from Eurasia.

The dangers of romanticizing Britain's 1976 heat wave

As I scrolled through social media on a hot afternoon in late June, a meme caught my attention. A black and white photo. A smiling young woman with water up to her knees. She appeared to be in a fountain, with many others ...

Space Rider reentry module undergoes 2.5 km drop tests

Space Rider is ESA's reusable spacecraft in development. It will be about the size of two minivans and will allow for many kinds of missions, ranging from pharmaceutical research to in-orbit manufacturing, visiting orbital ...

Model developed for more effective wildfire evacuation

At the year's halfway point, the National Interagency Fire Center reported active fires in 10 states, marking the highest number of individual fires in a decade. Some of the more vulnerable homes lie at the intersection of ...

Live dance performance syncs brainwaves, study suggests

A study published in iScience suggests that the magic of live performance art may be reflected in our brains. When people watched a live contemporary dance performance, their brainwaves synced up, signaling shared focus and ...

New study offers fix for veterinary nurse burnout

Burnout among veterinary nurses can affect the quality of pet care, according to La Trobe University researchers. But a new international study published in the journal Animals has identified how to fix the issue.

Major US teachers union teams up with AI giants

The long slow death of Norway's wild salmon

Waist-deep in a rain-swollen river, Christer Kristoffersen cast his line, landed it gently on the water, and caught ... nothing. Norway's iconic wild salmon is in dramatic decline, a victim of fish farming and climate change.

'Harmless' virus might trigger Parkinson's disease, researchers say

A common virus once thought harmless to humans might be linked to Parkinson's disease, a new study says. The germ, Human Pegivirus (HPgV), was found in half the autopsied brains of patients with Parkinson's, but not in any ...
