...cause a pandemic. Now they are watching a pandemic unfold in front of their eyes. When he talks about influenza, Daniels tends to use his hand as a visual aid, cupping his palm to mimic the virus's spherical structure and pretending his curled fingers are the sphere's protein spikes. As he looks down at his hand, his face breaks into a wry smile. "Forget the pandemic strain for a second and consider seasonal flu," he says. "How this virus can continue to evolve, maintain its viability no matter what we throw at it and cause us problems...
...been reported in Mexico and the first samples of the virus were on their way to London for examination. A virologist who has studied flu for more than 30 years, Daniels knew exactly what he was looking for. Influenza A viruses - the type that can cause pandemics - use a protein called hemagglutinin to bind to the cells of their animal hosts. When a virus jumps from animals to humans, its contagiousness is largely determined by what is called the "binding specificity" of this protein. An alpha-2,3 binding specificity means the virus is well suited to the cells...
...species that evolved to dispose of many extra calories beyond what we need to live. Rats, among other species, have a far greater capacity to cope with excess calories than we do because they have more of a dark-colored tissue called brown fat. Brown fat helps produce a protein that switches off little cellular units called mitochondria, which are the cells' power plants: they help turn nutrients into energy. When they're switched off, animals don't get an energy boost. Instead, the animals literally get warmer. And as their temperature rises, calories burn effortlessly. (See TIME's health...
...joint swelling produced. A specific active ingredient of the turmeric worked better still. A rigorous protocol and pictures of the rats' normal and swollen joints convinced me there was a real effect. Further experiments by the group even showed how turmeric turns down inflammation, by blocking production of the protein that turns on the gene that tells tiny blood vessels to grow...
Fueled by Coke Zero and a double-chocolate protein bar, Vice President Joe Biden is roiling, ranting, being his usual self. Five mayors and county executives listen in silence on the other end of a White House speakerphone as the Delaware ear bender tries to ride herd on the stampede for dollars known as the American Recovery and Reinvestment Act, the $787 billion monster that is the largest domestic-spending effort in U.S. history. "My rear end is on the line just like yours," Biden barks, surrounded by a flock of aides in his West Wing office...
