Diets high in processed meat, fast food, and sugary drinks accelerate biological aging, even in young adults. Researchers measured biological age using epigenetic clocks, which track gene regulation changes over time. Pa...

New research reveals how the brain rapidly adapts to sensory changes using a feedback loop between the olfactory cortex and the olfactory bulb. Scientists trained mice to associate rewards with specific sounds and smells...

Women who develop postpartum depression (PPD) may have distinct neuroactive steroid levels during the third trimester of pregnancy. A study found that those with PPD had lower levels of pregnanolone, which reduces stress...

A new study finds that the bacteria Streptococcus anginosus is more abundant in the saliva and gut of people who have had a stroke and is associated with a higher risk of death and major cardiovascular events. Researcher...

Skyrmions are nanometer- to micrometer-sized magnetic whirls that exhibit particle-like properties and can be moved efficiently by electrical currents. These properties make skyrmions an excellent system for new types of...

It's a new way to create same-sex biological offspring--but the approach is not ready for humans. The post Mice With Two Dads Reach Adulthood Thanks to CRISPR appeared first on SingularityHub.

A woman with heart failure was kept alive long enough to receive a heart transplant, in part thanks to newly developed stem-cell-derived heart tissue grafts.

Mice that were free to scratch their itchy ears saw the number of immune cells go up and levels of infection-causing bacteria decline

Some US states may see the number of power cuts caused by hurricanes jump by 60 per cent by 2100 in a high-emissions scenario, affecting tens of millions each decade

Astronomers have retracted the discovery of a new asteroid after realizing the object was the remains of Elon Musk's Tesla Roadster and its driver "Starman," which were launched into space in 2018.

A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 perovskite crystals as a promising platform for integration into lateral microchips--a new concept ...

A team of researchers from Universidad Carlos III de Madrid (UC3M) has developed an innovative technique that allows the production of regular oil lenses of uniform size on the surface of water in a simple and reproducib...

People receiving talking therapy for mild to severe depression reported greater improvements to their symptoms when also taking creatine compared with those on a placebo

The role of electrons and their negative charge in electric current is well established. Electrons also exhibit other intrinsic properties that are associated, for example, with considerable potential for enhancing data ...

Burn marks left on trees show that fires occurred frequently in North America from 1750 to 1880, but they tended to be less severe than modern fires and may have even been beneficial to forests

A new study suggests the Atlantic Meridional Overturning Circulation has not weakened since the 1960s -- but there's no doubt the circulation will slow in the future, experts say.

Detecting dark matter, the elusive type of matter predicted to account for most of the universe's mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this mat...

"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs."

Alkaptonuria is an unusual disorder caused by a defect in protein metabolism.

Gravitational waves offer a 'cosmic DNA test' for black holes

"Our measurements imply that the supermassive black hole mass is 10% of the stellar mass in the galaxies we studied."

How can the latest technology, such as solar cells, be improved? An international research team led by the University of Göttingen is helping to find answers to questions like this with a new technique. For the first ti...
