Now, the government is planning to augment family-based care with a social safety net

Contributors It was while he was working in a German clinical obesity and diabetes lab that Christian Weyer realized willpower only went so far in helping patients lose weight. Motivated by his desire to understand the pathophysiology of the two diseases, Weyer left the clinical world and eventually signed on with San Diego-based Amylin Pharmaceuticals in 2001 as vice president of Medical Development. “We treat [obesity] the same way we did

By Richard Gallagher Stumbling Towards Nirvana The promises of personalized medicine have failed to materialize. That may be about to change. The $1,000 genome will be an incredible technological achievement. But not necessarily a great medical one.

Mail A Theory, Resisted I would be very skeptical of a claim that there won’t be any selection for resistance in the malaria control agents (such as a fungus that kills mosquitoes after they reproduce but before they become infectious) in “Evolution, Resisted.”1 If there is any reproductive difference between fungal-susceptible and slightly resistant mosquitoes, there will be selection, even if it is just a little bit. The heavier the challeng

By Alissa Poh Subsidized science Baltimore-based company Champions Biotechnology has a business tale to tell, one reminiscent of Robin Hood. But there’s no robbing of the rich in this story. Rather, Champions uses revenue from premium services offered to wealthy clients to subsidize risky—and hard-to-fund—research. The subsidized science, a twist on standard xenografts, is based on an old concept dating back to the 1970s. Instead o

By Steven Wiley Speak Your Mind You don’t like my ideas? Tell me to my face, please. Disagree- ments among scientists do not go away simply because people are reluctant to argue in public. I am frequently struck by the paradoxical behavior of biologists. Recently, I attended a conference on biofuel development that included a discussion of the feasibility of deriving fuels from algae. In the open meeting, only a few biologists voi

As it passes through the sections of the tubule, the majority of the fluid and electrolytes are transported back into the plasma, leaving the waste products behind, which pass on to the collecting duct system, the urethra, and out of the body. Importantly, the quantity of

By Jef Akst Mechanical Forces in the Ear Online Extra Sound comes in the form of waves of compressed air, and detecting that sound is wholly dependent on the ear's ability to convert variations in air pressure to chemical signals that can be interpreted by the brain. When sound enters the ear, it deflects the eardrum that lies at the junction of the outer and middle ears. This deflection is then transmitted through the middle ear to a small membrane at the o
