The Milky Way may have a twin. The discovery of the most distant spiral galaxy to date may change the way we think about both the speed and process in which such systems are birthed, an international team led by the University of Geneva (UNIGE) reported in the journal Astronomy & Astrophysics. Astrophysicists have long thought that large spiral galaxies like the Milky Way form over several billion years in a chaotic process and initially form irregular shapes. But the James Webb Space Telesc ...read more

Sometimes a big medical problem requires a massive research effort. Scientists have done just that for osteoarthritis, a condition that could affect a billion people globally by 2050. Their enormous effort could help identify existing drugs suitable to treat arthritis, develop new ones specifically targeted to the disease, and, eventually create tailored approaches based on an individual arthritis sufferer’s genetic makeup. These three approaches are essentially at different heights on the dru ...read more

Just because Homo sapiens hadn’t yet developed the SPF rating system 41,000 years ago didn’t mean that they were unaware that solar radiation could prove hazardous.H. sapiens applied some form of sunscreen, shielded themselves from UV rays with clothes, and avoided the ravages of the sun by hiding in caves, according to an article in the journal Science Advances. In fact, those strategies may have helped their populations expand throughout Europe and Asia during a time when Neanderthals, who ...read more

Crocodiles are persistent — not just in their deadly pursuit of prey, but in terms of their existence. The contemporary species hails from a 230-million-year lineage that has survived two mass extinction events.A study in the journal Palaeontology identifies flexibility as a key to their longevity. Crocodylians that survived over millions of years can eat a variety of foods and live in multiple habitats. Understanding this level of adaptability could help threatened species survive. “Extinct ...read more

The Dolní Vestonice Portrait Head is just 2 inches tall and 1 inch wide. It’s a tiny face carved into an ivory mammoth tusk, but what it lacks in size, it makes up for in significance. Uncovered in the 1920s in the South Moravian region of the Czech Republic, the figure, which dates back 26,000 years, is thought to be the oldest known personal portrait.During the late Paleolithic Period, a group of mammoth-hunting ancient humans set up camp in the Dolní Věstonice region of what is now the C ...read more

Did the chemical components necessary to create water on Earth come from space or already exist here? One prevailing notion holds that asteroids containing either water of its building blocks bombarded the planet. But now, a team of researchers have produced evidence that those building blocks were here since early in the planet’s history, according to a study published in the journal Icarus.Pinpointing when and where Earth’s hydrogen is an essential key to understanding how life arose on th ...read more

Sauerkraut packs a punch, and not just for your taste buds. Famous for its tangy, sour, and slightly salty taste, sauerkraut has long been noted for being both nutritious and healthy, having been tied to a host of anti-inflammatory, antioxidant, and anti-carcinogenic activities. Now, a new study in Applied and Environmental Microbiology adds additional support to sauerkraut’s healthiness, showing that the topping may help out your gut, possibly thanks to its wealth of metabolic products, or me ...read more
