Scientists say they have found a way to disarm the AIDS virus in research that could lead to a vaccine.  Researchers have discovered that if they eliminate a cholesterol membrane surrounding the virus, HIV cannot disrupt communication among disease-fighting cells and the immune system returns to normal.  

Willerth and her team studied approximately 15,000 different versions of the virus-something that has never been done before. This information has allowed them to locate the specific genes of the virus that were resistant to the drugs-knowledge that could ultimately help researchers develop more effective treatments for HIV.

Our hard drives are divided into small sections of memory called sectors. Boot sector is the first sector containing Master Boot Records (MBR), which is responsible to boot up the operating system from system files.

Harvard researchers have created nanodevices made of DNA that self-assemble and can be programmed to move and change shape on demand. The nanodevice structure is based on the principle of tensegrity: its strength and stability results from the way it distributes and balances the counteracting forces of tension and compression. This new technology could lead to nanoscale medical devices and drug delivery systems, such as virus mimics that introduce drugs directly into diseased cells. Or it could one day be used to reprogram human stem cells to regenerate different kinds of injured organs and tissue.
