The number of AIDS cases worldwide fell by more than 6 million cases this year to 33.2 million, global health officials said Tuesday. But the decline is mostly on paper.
Most people spend most of their day sitting with relatively idle muscles. Health professionals advise that at least 30 minutes of activity at least 5 days a week will counteract health concerns, such as cardiovascular disease, diabetes and obesity that may result from inactivity. Now, researchers at the University of Missouri-Columbia say a new model regarding physical activity recommendations is emerging. New research shows that what people do in the other 15 and a half hours of their waking day is just as important, or more so, than the time they spend actively exercising.
"Many activities like talking on the phone or watching a child's ballgame can be done just as enjoyably upright, and you burn double the number of calories while you're doing it," said Marc Hamilton, an associate professor of biomedical sciences whose work was recently published in Diabetes. "We're pretty stationary when we're talking on the phone or sitting in a chair at a ballgame, but if you stand, you're probably going to pace or move around."

Industry special interests are burying information on cancer-causing chemicals and, according to watchdog groups, the government is helping them do it -- in the name of "data quality."
A lush, atmospheric drama, The Constant Gardener brings unprecedented exposure to crucial issues facing the Western pharmaceutical industry and all those who partake of it. Set mostly in a sun-dappled Kenya and based on a John le Carré thriller, the film is a fierce but flawed indictment of Big Pharma's complicity in African illness and poverty.
Prosecutors have charged three medical staff at a private clinic in southern Russia with illegally testing Belgian-made vaccines on children between one and two years of age.
The clinic in the city of Volgograd tested the Varilrix vaccine against chickenpox, and a measles, mumps and rubella vaccine, Priorix-Tetra, on a total of 112 children under a 2005 contract with the Belgian giant GlaxoSmithKline.
"Preliminary investigations showed that the doctors, seeking material benefits, conducted clinical tests of the vaccines with no regard for the children's lives and health," prosecutors said.
Prosecutors said the parents had been unaware of the trials and raised questions when their children fell ill after receiving the vaccines, which work by causing the body to produce its own immunity against the disease.

The United Nations has slashed its estimates of how many people are infected with the AIDS virus, from nearly 40 million to 33 million.
ATLANTA - For decades, heart disease death rates have been falling. But a new study shows a troubling turn _ more women under 45 are dying of heart disease due to clogged arteries, and the death rate for men that age has leveled off.
Luanda, Angola -- The World Health Organization says it is searching for the origin of a mystery illness that has struck more than 370 people in Angola.
Symptoms include extreme drowsiness and loss of muscle control, the United Nations agency says in a report on its Web site. The symptoms are most extreme in children, the report says.

OHSU study reveals how low-dose melatonin taken in the afternoon helps most winter depressives whose physiological clocks are off kilter due to the later winter sunrise
Researchers at Oregon Health & Science University(OHSU) have found that melatonin, a naturally occurring brain substance, can relieve the doldrums of winter depression, also known as seasonal affective disorder, or SAD. The study is publishing online this week in the Proceedings of the National Academy of Science.
The study was led by Alfred Lewy, M.D., Ph.D., an internationally recognized pioneer in the study of circadian (24-hour) rhythm disturbances, such as those found in air travelers and shift workers, as well as in totally blind people.

Psychopaths have physical abnormalities in two key brain structures responsible for functions ranging from fear detection to information processing, a USC clinical neuroscientist has found in two studies that suggest a neuro-developmental basis to the disorder.
Adrian Raine, a professor of psychology and neuroscience in the USC College of Letters, Arts & Sciences, focused his research on two parts of the brain: the hippocampus, a portion of the temporal lobe that regulates aggression and transfers information into memory; and the corpus callosum, a bridge of nerve fibers that connects the cerebral hemispheres.
"Scientists have implicated different brain regions with respect to antisocial and aggressive behavior, and all are important and relevant," Raine said.
"But it goes beyond that to the wiring. Unless these parts of the brain are properly wired together, they'll never communicate effectively. They'll never result in appropriate behavior," he said.
Although the neurobiological roots of psychopathy are still being explored, the key behavioral features of a psychopath have been clearly defined.
