Intense anti-viral drug therapy at the onset of HIV may help stunt the progression of the virus and protect the immune system, according to a study presented yesterday in the journal Nature...
...develop asthma has grown so dramatically over the past three decades. Bolstered by a handful of studies, the basic idea is that modern urban society is too clean for the kids' own good. A hundred years ago, children's immune systems would have faced all kinds of bacterial and viral infections. Today those immune systems don't know what to do in our supersanitized environment, so they wind up attacking pollen, dust mites and other usually innocuous substances instead. In the worst cases, a dangerous overreaction occurs that can shut down the lungs, killing the child...
...Viral diseases, along with insect infestations, are a major cause of crop loss in Africa, observes Kenyan plant scientist Florence Wambugu. African sweet-potato fields, for example, yield only 2.4 tons per acre, vs. more than double that in the rest of the world. Soon Wambugu hopes to start raising those yields by introducing a transgenic sweet potato that is resistant to the feathery mottle virus. There really is no other option, explains Wambugu, who currently directs the International Service for the Acquisition of Agri-biotech Applications in Nairobi. "You can't control the virus in the field...
...clarity, elegance and durability of a well-cut diamond. Though no two designs are alike, a Hoefler typeface--very few right angles, very few straight lines--is always exquisitely legible without sacrificing high style, somehow managing to synthesize classical elements with the churning pop culture. "Typefaces have a viral quality," says Hoefler. "It's always amazing to see where they wind up and how they transform the things they inhabit." Adds Frere-Jones: "When you're designing a typeface, you're not really making a product. You're building a machine that will go and make other products...
...every case of dementia--broadly defined as a progressive or permanent decline in intellectual function--is caused by Alzheimer's disease. In fact, there are dozens of conditions that can cause or mimic dementia, including depression, drug overdose, dehydration, anemia, syphilis, viral infections and vitamin deficiencies. Many of these are reversible if they are treated promptly, so it's important to get the proper diagnosis when you or someone you love starts experiencing serious mental deterioration...
