Risk reversal? “Diabetes drug might hike heart risk” (SN: 6/23/07, p. 397) reports 86 heart attacks among 15,560 rosiglitazone (Avandia) users, versus 72 others in a control group of 12,283. A study coauthor then says that “after statistical adjustment, that yields a 43 percent higher risk of heart attacks among rosiglitazone users.” Simple arithmetic would […]

Wasted youth The experiments with mice infected with the 1918 influenza virus are important but not surprising (“The Bad Fight: Immune systems harmed 1918 flu patients,” SN: 9/30/06, p. 211). John Barry’s The Great Influenza: The Epic Story of the Deadliest Plague in History (2004, Viking) explains that many, perhaps most, of the victims were […]

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.

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.
