HIV-1 spread through six transmission lines in the UK

...ling belief that the HIV epidemic in the UK can be traced back to one source, a new study suggests that HIV spread via at least six independent virus introductions and subsequent transmission chains. The findings, published in the latest issue of the Proceedings of the National Academy of Sciences, also sug...

Scientists discover how fish evolved to float at different sea depths

...ladder evolved from a primitive lung, which can be traced back 400 million years. These findings will help us to understand the diversity and success of modern fishes in their environment." Dr Berenbrink's research will be published in Science magazine on Friday, 18 March 2005. ...

Weizmann Institute scientists develop a new approach for directing treatment to metastasized prostate cancer in the bones.

... the potentially deadlyskin cancer. Thescientists traced the loss of hair color to the gradual dying off ofadult stem cells that form a reservoir that spawns a continuous supplyof new pigment-manufacturing cells, called melanocytes, that give hairits youthful hues. Not only do the non-specialized stem cell...

Poplar trees redirect resources in response to simulated attack

...eaves, where it is quickly converted to sugar, and traced the movement of this radiolabeled sugar through the plants using autoradiography and other techniques. Autoradiography allows for taking a snapshot in time showing the precise location of the radiotracer within the plant. With this and other techniqu...

The secret lives of whales

...ey might be related. Today, Smith and others have traced the succession of events that lead to these aggregations of animals. They feed these communities like feeding pigeons in a park except that in Smith’s case, they tow a dead whale out to the deep sea, place a transponder on it, and drop it to the sea ...
