If you take vitamin supplements, as I do, you'll want to pay attention to an emerging debate over how closely vitamins might be regulated in this country.
The outcome could be as severe as the Food and Drug Administration regulating vitamins like prescription drugs or as simple as more detailed labeling about vitamin supplements and their effects.
Using strands of genetic material, Purdue University scientists have constructed tiny delivery vehicles that can carry anticancer therapeutic agents directly to infected cells, offering a potential wealth of new treatments for chronic diseases.
Public health attorneys in California have potato chip makers in their sights for not listing a cancer-causing chemical present in many brands.
That chemical is acrylamide. It is an industrial chemical used in plastics, pesticides and sewage treatment that also can occur when starchy foods, such as chips, are processed at high temperatures.
The World Health Organization has said acrylamide may be responsible for up to one-third of all cancers caused by diet, as demonstrated by laboratory animal studies. Acrylamide is already on California's list of chemicals known to cause cancer, but some chipmakers haven't listed it on their product packaging as required by Proposition 65 statute.
Einstein/SUNY Stony Brook/Rutgers team find quantifiable love responses in fMRIs of 17 young people who were newly, madly in love. Intense love was a strong basic reward "drive" very different from sex, the New York City-area team (neuroscientist, anthropologist, social psychologist) shows.Two big surprises: fMRIs changed markedly over time, and activation regions (including the VTA) associated with intense romantic love are mostly on the brain's right side.

Katherine Moskwin, 71, a retired medical transcriptionist, started noticing that her short-term memory was shot awhile ago.
"I'd go into a room and forget what I was coming for," she said. "I'd be dialing the phone and stop and say 'Who am I dialing.' "
That's one reason Moskwin is trying out a new software program from San Francisco's Posit Science Corp.
To that end, the researchers plan to directly stimulate the layer underneath the dead photoreceptors using a system that looks like a cousin of the high-tech visor blind engineer Lt. Geordi La Forge wore in Star Trek: The Next Generation. It consists of a tiny video camera mounted on transparent "virtual reality" style goggles.
The long-held belief that older people perform slower and worse than younger people has been proven wrong. In a study published today in Neuron, psychologists from McMaster University discovered that the ageing process actually improves certain abilities: Older people appear to be better and faster at grasping the big picture than their younger counterparts.

LIKE it or not, genetically modified food is already in the South African food chain quite possibly in the next snack you bite into.
Maize and soya, the two genetically modified food crops approved by government, are used in a wide variety of processed foods.
Harnack and colleagues from the University of Minnesota analyzed the quantities and types of foods and nutrients marketed in America over the past three decades, and found that the per capita availability of energy increased 15% between 1970 and 1994. The availability of fish and chicken, fresh and frozen fruits and vegetables, and low fat milk.
