Phys.org / How face-building genes get ready early: Genome folding may prime crucial DNA switches
Early in development, a group of migrating cells called cranial neural crest cells go on to form many different parts of the face, including the nose, jaw, ears, and throat. To build these structures correctly, genes must ...
Phys.org / Rare seals hide in underwater bubble caves to escape tourists
The uninhabited islet of Formicula in Greece's Inner Ionian archipelago is a popular tourist draw for its clear waters, swimming spots, and marine diversity. A major attraction is the Mediterranean monk seal, one of the world's ...
Phys.org / How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control ...
Phys.org / Consistency check casts doubt on evolving dark energy
Cosmologists have long struggled to determine whether the universe's accelerating expansion is being driven by a simple cosmological constant, or whether dark energy's influence is evolving over time. In a new analysis published ...
Phys.org / Less low cloud cover lets in more heat from the sun—and may lock in centuries of sea level rise
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
Phys.org / Tritium-infused graphene could sharpen the hunt for neutrino mass
While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, ...
Phys.org / Climate catch-22: Cleaning up air pollution could speed key Atlantic current decline
It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts ...
Phys.org / A de-extinction company has hatched live chicks from an artificial eggshell
A biotech company that aims to resurrect lost creatures said Tuesday it has hatched live chicks in an artificial environment—a development that was met with mixed reviews from scientists and critics of its de-extinction mission.
Phys.org / MeerKAT discovers 15 new millisecond pulsars in a well known globular cluster
Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest ...
Phys.org / Chemists use sea sponge bacteria to create new molecules for drug discovery
Florida State University chemists have synthesized new molecules derived from bacteria found in a Pacific Ocean sea sponge, a breakthrough for the future of drug development, particularly for rare forms of cancer.
Phys.org / SIRT6 protein could protect against age-related breakdown in chromatin, possibly help reverse aging
Researchers at Bar-Ilan University have successfully restored youthful patterns of DNA organization in the livers of old mice, reversing key molecular features associated with aging. The study, published in Nature Communications, ...
Phys.org / New 'Happy-Face' spider species discovered in the Indian Himalayas
Vibrant, tiny, and sporting a bright red grin on its back, the Happy-Face spider is one of the most famous and recognizable arachnids in the world. For over a century, this cheerful-looking creature was thought to be a unique ...
