HIV after DARC
A gene variant prevalent in people of African descent increases the risk of HIV infection but also helps slow disease progression.

Parasitic plant gets more than a meal
The parasitic vine known as dodder really sucks. It pierces the tissue of other plants — some of which are important crops — extracting water and nutrients needed for its own growth. But it also consumes molecules that scientists could manipulate to bring on the parasite’s demise.

New HIV inhibitor
A new HIV drug can, when combined with other therapies, suppress even the most drug-resistant strains of the virus that causes AIDS, scientists report in two papers in the July 24 New England Journal of Medicine.

A chink in flu’s armor
Finding the shape of a protein that enables the flu virus to replicate points to ways to combat the disease.

Promising HIV gel fails in latest trial
Halted in trials, an anti-HIV gel is ineffective, but may not add to risk of infection, as previously thought.

Nanomagnets tackle cancer
Under the influence of an external magnetic field, tiny magnets act as highly localized space heaters, warming to temperatures that kill adjacent cancer cells.

Making T cells tougher against HIV
Delivering small interfering RNAs, or siRNAs, to human immune cells in mice protects the cells from HIV and suggests future therapy for patients.

H9N2 avian flu strain has pandemic potential
Just one change in a strain of avian flu virus makes it transmissible by direct contact in ferrets, but the virus still lacks the ability to spread by airborne particles.

Finding the golden genes
Advances in gene therapy could tempt some athletes to enhance their genetic makeup, leading some researchers to work on detection methods just in case.

Immune cells show long-term memory
Survivors of the 1918 Spanish flu pandemic still make antibodies against the virus, revealing a long-lived immunity previously thought impossible.

Deep sea viruses are an unexpected ringer
Deep-sea vent waters harbor high numbers virus-carrying bacteria. The viruses may actually help the bacteria survive the harsh vent environments.
