Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...for maintaining immunity. Another protein — gp41 — then enables HIV to penetrate a T-cell membrane. Fusion takes place specifically through a short stretch of gp41 called fusion peptide 23, or FP-23 for short. Prior studies have shown that FP-23 fuses with, and can even break apart, blood cells and other ...

Genomic Analysis Uncovers New Targets for HIV Vaccine

..., known as the viral load, gradually decreases and then levels off, a period during which patients do not exhibit symptoms of their disease. The viral load during this leveling out is an indication of how well the patients' own immune system is battling the virus, and this is the point in the infection's ...

...ing p53 and the other containing healthy p53. They then looked for any of the 500 known human microRNAs that are activated only in cells containing p53. It turned out that the miR-34a gene is turned on by p53, and in fact, experiments demonstrated that p53 binds directly to the genetic material near mi...

Bigger horns equal better genes

... "[The horns] require a lot of energy to build and then carry around. They can be a meter long and are quite heavy, and the ibex carries them for their lifetime, unlike antlers which are shed every year. They also cause the ibex to lose heat in winter, because their core is heavily vascularized." Foun...
