The Food and Drug Administration recently approved a shingles vaccine for adults age 60 and older. Anyone who has ever had chicken pox is susceptible to the shingles virus, which can cause blisters and extreme pain. More than 1 million Americans are afflicted with shingles each year.

Some experts think the cost of caring for Alzheimer’s patients could soon be more than our economy can bear.Providing care for people with Alzheimer’s disease costs the U.S. more than $100 billion per year, but less than $1 billion is spent by the government for research. Politicians argue that caring for people who already have the disease should be the top fiscal priority, while researchers believe more money should be spent to find better treatments, vaccinations or a cure. Great strides have been made with Alzheimer’s research in recent years, and more effective treatment and prevention could save billions in patient care.

WUSM researchers believe a vitamin vitamin natually found in carrots and tomatoes can protect skin from sunburns. The vitamin. zeaxanthin, is a natural pigment found in fruits and vegetables.

Charles Huddleston performs a pediatric lung transplant.A team of researchers at the School of Medicine has found that using lobes of lungs from living donors improves the chances of short-term survival for children who require a second lung transplant. Living-donor lung retransplantation involves removing a lower lobe, or about one-third of a lung, from each of two healthy adult donors and then transplanting the lobes as replacement lungs into a child.

Red zones in this brain map suggest frontal parts of the brain are particularly sensitive to erotic content.A new study suggests the brain is quickly turned on and “tuned in” when a person views erotic images. Researchers at the School of Medicine measured brainwave activity in women as they viewed a series of slides that contained various scenes from water skiers to snarling dogs to partially-clad couples in sensual poses. When study volunteers viewed erotic pictures, their brains produced electrical responses that were stronger than those elicited by other material, no matter how pleasant or disturbing the other material may have been.

Eliminating a molecular signal can help protect a neuron (show here) from destructive immune system cells.It may sound like a case of blame the victim, but researchers at the School of Medicine have shown that cells in the central nervous system can sometimes send out signals that invite hostile immune system attacks. In mice the researchers studied, this invitation resulted in damage to the protective covering of nerves, causing a disease resembling multiple sclerosis. The researchers found that they could prevent destructive immune cells from entering nervous system tissue by eliminating a molecular switch that sends “come here” messages to immune cells.

These brain images point out the areas most consistently active during a variety of cognitive tasks.Scientists have used data from scans of 183 subjects to identify brain areas that consistently become active in a variety of cognitive tasks, such as reading, learning a rhythm or analyzing a picture. If the brain in action can be compared to a symphony, with specialized sections required to pitch in at the right time to produce the desired melody, then the regions highlighted by the new study may be likened to conductors, researchers at the School of Medicine assert.
