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 ...
Medical Xpress / Volatile work hours cut access to employer health insurance, study finds
In the 46 years since Dolly Parton wrote the workers' anthem "9 to 5," American jobs, and access to employment-based health insurance, have changed a lot.
Phys.org / Ancient DNA traces medieval migration from Sweden to Finland
A new study led by the University of Turku provides new insights into the population history of Finland during the Late Iron Age and the Middle Ages. The researchers analyzed the genomes of people who lived in southwestern ...
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. ...
Medical Xpress / Experimental drug shows potential for hard-to-treat heart disease
An experimental drug has been shown to improve symptoms, exercise capacity and heart failure status in patients with an inherited heart disease, according to a pair of newly published studies.
Phys.org / High-resolution weather data could pinpoint neighborhoods facing greatest heat stress
Heat stress is a leading cause of weather-related deaths and can be especially dangerous in cities, where phenomena like urban heat islands drive temperatures higher than in surrounding rural areas. Now, a new dataset developed ...
Medical Xpress / Chromatin protein DAXX may help preserve brain immune cells during aging
As humans get older, their brains undergo various changes that can affect mental functions. The cells known to be affected by aging include microglia, the primary immune cells in the brain and spinal cord, which help eliminate ...
Phys.org / Four in 10 young people don't see 'buy now, pay later' as debt
The way a product is labeled can change how consumers think about it. "No added sugar" or "99% fat-free" can make food sound healthier than it really is.
Phys.org / New species of 240-million-year-old prehistoric animal could reshape dinosaur origins timeline
A new prehistoric animal species from Tanzania dating to around 240 million years ago, during the Triassic period, has been described by an international team of researchers. Led by the University of Bristol, the new species, ...
Medical Xpress / A blind retina isn't silent—and its noise may hinder efforts to restore sight
When retinitis pigmentosa takes a person's sight, the standard clinical test goes flat: no response, no signal, nothing. Yet the retina behind that flat line is anything but quiet.
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 ...
