thousands of health care workers. No experimental vaccine has ever been on a faster track toward widespread use.
Researchers used smart phones to track the sins and good deeds of more than 1200 people and confirmed what psychologists have long suspected: Religious and nonreligious people are equally prone to immoral acts. The new data are among the first to be gathered on moral behavior outside of the lab.
Some people get sick even after they get a flu shot. Why? One reason might be their gut bacteria. A new study reveals that a strong immune response to the flu vaccine relies in part on signals from the bugs inside us.
As two retracted stem cell papers have produced an almost unimaginable fallout—a national hero accused of scientific fraud, the revamping of one of Japan’s major research institutes, and the suicide of a respected cell biologist—researchers have privately and publicly asked how Nature could have published work that, in retrospect, seems so obviously flawed.
Spinosaurus isn't just the biggest carnivorous dinosaur—it's also the only known swimmer. Ninety-seven-million-year-old fossils have revealed that the 15-meter-long Spinosaurus(that's bigger than Tyrannosaurus Rex) was the only dino to make its home in the water, munching on sharks and giant fish.
