  • Gotcha! New test stalks diseases early

    Diseases sneak up on us. They begin triggering changes in the body long before we feel sick. But a new method has the potential to spot telltale signs early, before a disease gains a foothold. That could help doctors diagnose — and treat — disorders before they do too much damage.

    The new technique detects antibodies. These are substances made by the immune system. They stick to foreign...

  • Fattier yeast live long and prosper

    Many people frown at the thought of fattening up. But fats can be useful because they store energy. And new research finds that having extra fat might be good — for yeast, at least. Their “fat” cells can outlive lean ones.

    For now, it’s unclear what these results mean for people — or even simpler organisms such as worms and flies.

    Yeast consist of only a single cell. Still, the...

  • Concussed brains need time to heal

    Repeated hits to the head — even mild ones — can take their toll. But a new study shows that to let the brain recover, taking a few days to rest may be essential.

    A typical high school or college football player experiences about eight hits to the head each week of the football season. And those hits can add up. None may seem serious by itself. They may not even give rise to symptoms of...

  • Cell recount: People host far fewer germs

    For decades, scientists have been saying that our bodies are home to lots of germs. How many? About 10 bacteria for every truly human cell. But that old number, a new study finds, appears to be highly inaccurate. Humans do host lots of germs, it found — but only about 30 percent more germs than human cells, not 9,000 percent more.

    Researchers shared their new calculations online January...

  • Brain damage seen in potent-marijuana smokers

    People who smoke high-potency pot show signs of damage in a key part of their brain. The results of the new study, however, are limited. The brain scanning study was small. And it doesn’t show that marijuana caused the brain abnormality — only that the two go hand-in-hand.

    But the finding suggests that potency matters, says Tiago Reis Marques. This coauthor of the study is a psychiatrist...

  • Expert panel approves human gene editing

    WASHINGTON, D.C. — Recently, scientists have been using chemical “scissors” to edit, or change, the DNA in living organisms. This swapping out of parts of DNA could replace faulty genes. In theory, it also might make it possible to create designer babies that are smarter or better-looking than other individuals. But some people have questioned whether such tinkering with human cells would be...

  • Scientists discover itch-busting cells

    A fly tickling the hair on your arm can spark a maddening itch. Now, scientists have spotted nerve cells in mice that curb this light twiddling sensation. If humans have similar itch-busters, the results could lead to treatments for the millions of people who suffer from chronic, unstoppable itch.

    For many of these people, there are currently no good treatments. “This is a major problem...

  • News Brief: Rare gem may hold earliest sign of life

    Researchers have just reported the discovery of what could be the earliest evidence of life on Earth. If confirmed, life emerged at least 4.1 billion years ago. That would make it roughly 300 million years earlier than previous estimates.

    The oldest fossils known to show life date back to around 3.5 billion years ago. But what came before the life that made those fossils? It might have...

  • New light on brain science

    Flip a switch and you can turn on or off lights, fans and all sorts of other things. Individual nerve cells in the brain are now the latest addition to this list. Over the past decade, scientists have found a way to use light to control the brain’s nerve cells, or neurons.

    This new field is called optogenetics (OP-toh-jeh-NEH-tix). Opto- is a prefix that refers to light. Genetics deals...

  • Pain relief could come from a ‘drugstore’ for cells

    One of the worst kinds of pain might be chronic type caused by damaged nerves. It can last a long time. And there aren’t many treatments for it. But there is one treatment that helps in mice. And scientists now think they finally may understand how it works.

    For the treatment, scientists extract cells from the bone marrow of mice. These cells are then injected into the spinal cord of a...
