A Step Closer to Vaccine Against HIV That Causes AIDS

Posted:

In what can be seen as a move toward designing the first effective vaccine against HIV, the virus that causes AIDS, researchers report new insights into how a family of rare, highly powerful antibodies bind to HIV and neutralize it to prevent it from infecting human cells. The antibodies were isolated from people infected with HIV and work against a wide range of HIV strains. The researchers described the study today at the 244supth/sup National Meeting (and) Exposition ...

Stem Cells - New Findings

Posted:

The role of a protein called Mof in preserving the 'stem-ness' of stem cells has been discovered by scientists. Their results show that Mof plays a key role in the "epigenetics" of stem cells -- that is, helping stem cells read and use their DNA. One of the key questions in stem cell research is what keeps stem cells in a kind of eternal youth, and then allows them to start "growing up" to be a specific type of tissue. Dou, an associate professor ...

Extract from green tea found to be effective at shrinking skin cancer tumours, find researchers. The University of Strathclyde team made 40 per cent of human skin cancer tumours disappear using the compound, called epigallocatechin gallate, in a laboratory study. Previous attempts to capitalise on its cancer-fighting properties have failed because scientists used intravenous drips, which failed to deliver enough of the extract to the tumours ...

Teens Who Sleep Less for Extra Study Hours Likely to Have Academic Problems

Posted:

No matter how much a high school student generally studies each day, if that student gives up sleep in order to study more than usual, he or she is more likely to have academic problems the following day.
