Mosquitoes spread a lot of disease, but they are not just “flying hypodermic needles.” As we rush to protect ourselves against a virus that can cause permanent brain damage, how can we understand and control the mosquitoes that spread West Nile? More
Disease and Treatment
Finding the killers — in advance
Can we spot these young, male, angry, frustrated killers in advance? Will science help us identify them in time? More
Know thy genes, know thyself?
Advances in genetics raise the stakes in genetic counseling, but the genetic role in disease can be complicated, elusive. What role do faith, personality and knowledge play in the complex discussions over genetic disease? More
A Story of the Bacterium and the Fly
Bacteria can help or harm their hosts. Now we hear how one genus of bacteria can multiply fly reproduction. In this symbiosis, both parties benefit. This bacterium also alters insect immunity, and could lead to new tactics for killing horrific parasites. More
Short of meds…
Contaminated injection blamed for mini-epidemic. Why are hospitals running out of generic drugs, anesthetics and antibiotics? More
In praise of the lowly apple
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? More
Flying virus!
Flu virus can fly on aerosols after a sneeze, cough, even a breath. They can stay aloft for hours, long enough to find another victim. More
Cholera: Haiti’s latest scourge
Cholera can kill with record speed. The bacterium is easy to control — if wastewater and drinking water are treated. Haiti — chronically corrupt, painfully poor, and wasted by the January quake, is paradise for the cholera bug. How is cholera prevented, and what are the enduring gifts of this deadly bug? More
Key to caloric restriction found!
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? More
A strike against stroke?
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? More
Stem cell battle resumes
A federal court has thrown the field of embryonic stem cell research into confusion. Last week, research that destroys embryos could not get federal bucks — even if those embryos were doomed or destroyed years ago. This week, it can. How is the legal yo-yo affecting researchers — and desperate patients? More
Legal pot? “No,” says California
The science behind medical marijuana is emerging. Some tests show that it dulls pain in cancer, rheumatoid arthritis, multiple sclerosis and AIDS. Why is medical marijuana so difficult to explore? What’s coming to the market? More
Fearing flu, finding vaccine
How is flu vaccine is made in eggs and animal cells? What is being done to protect us against a fast-changing, deadly virus? More
Swine flu
Genetic tests go mainstream
Companies are marketing genetic tests direct to consumers. Some tests can be lifesavers. But many tests return confusing results, which even doctors have a hard time interpreting. More
