Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain. Researchers at UC San Francisco found that older adults with “normal” but lower levels of active B12 showed signs of slower thinking, delayed visual processing,
Ringed seals are among the most common marine mammals in the Canadian Arctic. They strongly rely on sea ice as a habitat, breathing through holes they maintain in the frozen surface, giving birth in snow lairs and diving beneath the ice to hunt Arctic cod and small crustaceans.
Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using conventional experimental techniques and instruments.
Vaccine misinformation, nurse and doctor shortages and crowded living arrangements may be behind soaring rates of diphtheria in remote Indigenous communities in Australia
In the relatively short time they've been around, online dating apps have transformed how we hook up, date and fall in love. These apps have long been characterized by "swipe logic": users are shown profiles of others and must swipe left or right to decide whether they like
