Phys.org / Record-breaking levels of plastic found in seabirds, with almost 900 pieces found in one bird alone

For more than a decade, it was thought that the world's most plastic-polluted birds couldn't get any more contaminated by the man-made material. But then, from 2023–2026, the record was broken every single year.

Phys.org / Mitotic chromosomes may assemble from pre-existing chromatin 'building blocks' during cell division

Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two daughter cells during cell division. To achieve this, the copied DNA is condensed into thick, short ...

Phys.org / Greenhouse gas benefits of agricultural irrigation far outweigh emissions costs, study finds

Irrigating U.S. crops prevents higher greenhouse gas emissions by avoiding land conversion, new research by Colorado State University shows. Agricultural irrigation allows the United States to grow more food on less land. ...

Phys.org / Heat-stable enzyme from deep-sea microbe turns nitrogen gas into ammonia

Microorganisms can do remarkable things—for example, nitrogen fixation, the conversion of nitrogen gas (N₂) into a form that organisms can use. Although nitrogen gas makes up around 78% of Earth's atmosphere, plants and animals ...

Phys.org / Satellite data reveal ESG scores track public image more than actual forest loss

Environmental sustainability researchers at NUS found that widely used environmental, social and governance (ESG) ratings often fail to reflect companies' actual exposure to deforestation, highlighting the need to integrate ...

Phys.org / Avoiding a sticky situation: How cells stop messenger RNAs from clumping together

Messenger RNA, or mRNA, is best known for carrying genetic instructions from DNA to the cellular machinery that makes proteins. But all RNA molecules have another, less appreciated property: They are naturally sticky.

Phys.org / For many group-living females, breeding and raising young are shared endeavors

Some female animals living in groups raise offspring that are not their own, sometimes without reproducing themselves. While the behavior of cooperatively breeding species is well documented, some aspects remain poorly understood.
