...Life Sciences 1a and 1b do not give you a good idea of the breadth of the human evolutionary biology or molecular and cellular biology concentrations. Course titles can also be misleading, so take a careful look at the class syllabus and reserve reading list. (Expecting Sigmund Freud in your psychology class? Wrong. Try English or philosophy instead.) All this being said, if you already have an inkling of what you’d like to concentrate in, do get the introductory requirement course over with. And if you are even the slightest bit interested, take CS 50 before...
...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.

Three years ago, the mobile horizon looked very different from how it has turned out. Google was working on Android, its open-source-ish operating system for cellular phones. Its strategy: Let a million mobile phones blossom! So long as Google products - search, maps, documents - ran on them, Google would win, since Google ads would, presumably, continue to flow. Google would be baked into Android, of course, but it would also be on BlackBerrys and Nokias and Windows Mobile phones. And when the first iPhone went on sale two summers ago, Google apps, including YouTube integration, were core...
...PDAs for Hewlett-Packard and other companies. In mid-2007, about the same time that Apple launched the iPhone, HTC started selling its own touchscreen phone. The HTC Touch became popular in Asia, partly because it was cheaper than the iPhone and could be used on a variety of cellular networks. Based on that success, HTC now ranks fourth in market share for smart phones globally, according to research firm IDC. The company, which is about to release a new smart phone, the Hero, hopes to ultimately become one of the top five handset makers in the world...
Rapamycin's life-extending effect has been demonstrated by other researchers in past studies of worms, fruit flies and yeast; the drug appears to interfere with a similar cellular process in those species too. "I think this is a big leap from those invertebrate species to mammals," says Strong, who is also a senior research scientist for the Department of Veteran Affairs. "This gives us a good idea that perhaps it would work in humans...
