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.
