Assassin Cells Slay Hidden HIV

Human trials set next year

(Newser) - A promising new treatment for AIDS may be in the works, with the discovery that genetically engineered immune cells can detect and destroy HIV even when the virus tries to hide by mutating. The so-called “assassin” cells, created from the T-cells of an HIV patient, have worked their magic...

Bullies May Enjoy Inflicting Pain

Brain scans show agressors feel reward watching others suffer

(Newser) - Bullies appear to enjoy seeing other people in pain, Reuters reports. Researchers in Chicago took brain scans of two sample groups of teens while showing them videos of one person hurting another. When showed violence, one group of teens, who were diagnosed with aggressive-conduct disorder and had recently attacked schoolmates,...

Vitamin Could Delay Onset of Alzheimer's

B3 pills caused big improvement in mice; human trials to begin

(Newser) - A simple dose of vitamin B3 may be one of the keys to combating the brain deterioration caused by Alzheimer’s disease, California scientists say. The team found that diseased mice given high levels of the vitamin retained normal memory ability over the four months of a study, and healthy...

'Water Monster' About to Die Off

Mexican salamander suffers in polluted canals and lagoons

(Newser) - Mexico’s “water monster"—a mere foot long but once central to the Aztec legend and diet—is close to dying out, the AP reports. Axolotls have long endured in the polluted Venice-like canals of Lake Xochimilco in Mexico City, but baby-gobbling fish and ebbing water quality are...

Stress Pushes Animals to Binge, Too

House pets feel human worries; lab animals turn to high-fat treats

(Newser) - Animals get stressed out just like humans, and they even cope anthropomorphically, binging on sweet, fatty foods, LiveScience reports.

Imaging shows brain quickly switches among tasks instead

(Newser) - Pull your ears away from that cell phone: Multitasking is a myth. New research shows we can’t really concentrate on two things at once; rather, the executive functions of the brain sweep quickly between multiple tasks. It’s thought that survival and the hunt made this rapid refocusing of...

Docs Tout Safer, Non-Embryonic Stem Cells

Virus, used in mice, repurposes adult cells with no risk of cancer

(Newser) - Scientists have discovered a safer way to turn adult cells into stem cells, the Boston Globe reports. The cells, similar to those harvested from embryos, are called induced pluripotent stem, or iPS, cells; Japanese researchers introduced the method 2 years ago. But the Japanese used retroviruses, which can cause cancer;...

Autism-Reversing Drugs Show Promise

MIT scientists stumbled onto workaround for misfiring brain system

(Newser) - MIT scientists have discovered one of the mechanisms of Fragile X Syndrome, one cause of autism, and are developing drugs to treat it, NPR reports.
