Scientists document complex genomic events leading to the birth of new genes

... known to play a leading role in evolution for the creation of new genes," explained Francesca Ciccarelli, Ph.D., lead author on the study. The key to this, however, is that the duplicated copies of genes very quickly evolve functions that are significantly different than those of their progenitors. Natural ...

Potential treatments for neurofibromatosis

...te chemicals called growth factors that enable the creation of blood vessels. The IU investigators now are identifying drugs that can disrupt the function of mast cells and their proteins in ways that they believe will starve the tumors. "It's much easier to develop targets against a non-malignant cell than...

Nano-bumps could help repair clogged blood vessels

...rom attaching to the scaffolding and prompting the creation of scar tissue, which can build up inside blood vessels and interfere with blood flow. "If a stent doesn't attach firmly it can become loose, and parts of it will actually break off and go down the bloodstream," Webster said. "Essentially, what we'v...

Gladstone investigators discover how resting T cells avoid HIV infection

...ould include the early death of these cells or the creation of mutations in the chromosomes that might lead to cancer. "The possibility of exploiting the natural and potent antiviral properties of A3G to control HIV infection is very exciting," says Greene. "We have learned a great deal from our studies of h...

A New Species of Monkey is Discovered in Tanzania: The First in Africa for More Than 20 Years
