The neurohormone oxytocin is well-known for promoting social bonds including trust, empathy, positive memories, processing of bonding cues, and positive communication and generating pleasurable feelings, for example from art, exercise, or intimacy. Now, researchers from Michigan State University show that in zebrafish and human cell cultures, oxytocin has yet another, unsuspected, function: it stimulates stem cells derived from the heart’s ...

We all grow old and die, but we still don’t know why. Diet, exercise and stress all effect our lifespan, but the underlying processes that drive ageing remain a mystery. Often, we measure age by counting our years since birth and yet our cells know nothing of chronological time—our organs and tissues may age more rapidly or slowly regardless of ...

BGI Genomics, in collaboration with Southwest University, the State Key Laboratory of Silkworm Genome Biology, and other partners, has constructed a high-resolution pangenome dataset representing almost the entire genomic content in a silkworm. Previously, due to the scarcity of wild silkworms and technical limitations of former studies, many trait-associated sites were missing. This is the first research ever to digitize ...

“I’m a professional pin-in-a-haystack seeker,” geneticist Thijn Brummelkamp responds when asked why he excels at tracking down proteins and genes that other people did not find, despite the fact that some have managed to remain elusive for as long as forty years. His research group at the Netherlands Cancer Institute has once again managed to track down one of these “mystery ...

Taken as a share of the market price, the climate change impacts of mining the digital cryptocurrency Bitcoin is more comparable to the impacts of extracting and refining crude oil than mining gold, according to an analysis published in Scientific Reports by researchers at The University of New Mexico. The authors suggest that rather than being considered akin to ‘digital gold’, Bitcoin ...

Two of NASA’s Great Observatories, the James Webb Space Telescope and the Hubble Space Telescope, have captured views of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world’s first-ever in-space test for planetary defense. These observations of NASA’s Double Asteroid Redirection Test (DART) impact mark the first time that Webb and Hubble ...

For billions of years, the Milky Way’s largest satellite galaxies – the Large and Small Magellanic Clouds – have followed a perilous journey. Orbiting one another as they are pulled in toward our home galaxy, they have begun to unravel, leaving behind trails of gaseous debris. And yet – to the puzzlement of astronomers – these dwarf galaxies remain intact, with ongoing vigorous star ...

Despite a long-standing hypothesis that personality traits are relatively impervious to environmental pressures, the COVID-19 pandemic may have altered the trajectory of personality across the United States, especially in younger adults, according to a new study published this week in the open-access journal PLOS ONE by Angelina Sutin of Florida State University College of Medicine, and colleagues. Previous studies have generally found ...

Stressful life circumstances can affect how married couples interact, but can they affect how partners see each other? A person experiencing stress is more likely to notice their spouse’s negative behavior than positive, according to a new study published in Social Psychological and Personality Science. Prior research has focused on how stress influences behavior, but this study suggests that stress could affect ...

Scientists estimate that more than 95 percent of Earth’s oceans have never been observed, which means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Mars. The high cost of powering an underwater camera for a long time, by tethering it to a research vessel or sending a ...
