Among foodies, apples lack the “healthy-tasty” cachet of acai berries or pomegranates. But in a year-long study, apples produced major benefits in cholesterol and inflammation. After eating 75 grams of dry apple a day, the women even lost three pounds. Is there something not to love about apples?

People with a genetic case of dwarfism in Ecuador don’t get cancer or diabetes, and a new study links that benefit to the genetic changes we see when calories are severely restricted. Could blocking growth hormone in adulthood lead to serious health benefits?

Got flu? Then virus particles can enter the air aboard aerosols released by a sneeze, cough or even a breath. Smaller droplets can stay aloft for hours — so size matters. According to a new study, many droplets can float for an hour — plenty long enough to infect another victim.

It’s as sure as sunrise. Drink too much, and you’ll pay next morning: lassitude, nausea, headache, dizziness, and more specialized agonies will be cause for regret. Hangovers: If you can’t avoid them, will they cause you to drink less? Do fruitflies get hung over?

Three gross “biotherapies” are gaining medical attention, and two already have FDA approval as “medical devices” (?) ! Leeches can suck excess blood after surgery, and maggots remove dead tissue and kill bacteria in hard-to-heal wounds. Parasitic worms might fight ulcerative colitis — a widespread bowel disease. Maybe.

How do victims of domestic violence benefit from prayer? A series of interviews shows a range of mechanisms: from zoning out to offering psychic protection to allowing forgiveness. A new study shows how real benefits could emerge from an appeal to an “imaginary other.”

To stay young, science says you drastically cut calories. It works for fruitflies, rodents, monkeys, and every mammal that has been tested. A new study proves that the benefit requires the Sirt-3 gene. Could Sirt-3 be the key to an anti-aging drug treatment?

Aware that a small amount of function often returns after a stroke, neurologists have helped neurons recover after an experimental stroke. Mice that got a candidate drug that blocks GABA, the major inhibitory neurotransmitter, recovered up to half of their motor control. In the future, can we treat strokes that cannot be prevented?

Heard the rumor that people are happy — or not — depending on their genes and upbringing? “My bad,” says a 24-year study from Germany, which finds the opposite. Attitudes toward money, employment and neurotic mates all play a big role resetting your “happo-stat.”

Impacts and concussions can cause long-lasting, even permanent brain damage. Millions of Americans have traumatic brain injuries. Could experimental techniques help mice and people?
