Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, according to new studies by Howard Hughes Medical Institute researchers. The scientists were able to achieve the same results when they treated the [...]
When smell cells fail they call in stem cell reserves

Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear [...]

Researchers are adding to the list of cancer types for which pomegranates seem to halt growth. A recent study at the University of Wisconsin–Madison using a mouse model shows that consuming pomegranates could potentially help reduce the growth and spread of lung cancer cells or even prevent lung cancer from developing.

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine. These findings, which were published online March 20 in the Journal of [...]
A steady, high-fat diet is bad, but the news gets worse
Posted by: Derya on: April 23, 2007
So much for the adage, ‘All things in moderation.’ Researchers at the University of Calgary have found that people who consume a single, high-fat meal are more prone to suffer the physical consequences of stress than those who eat a low-fat meal.

Researchers have devised a clever way to activate neurons in a living mouse by shining light on the surface of the animal’s brain. The “light switch” that turns neurons on is actually a light-sensitive protein that is produced by algae. When this protein is genetically engineered into the neurons of living mice, researchers can precisely [...]
Recording a Cell’s Dying Gasp
Posted by: Derya on: April 21, 2007
Scientists in the United Kingdom have developed a way to monitor the health of individual cells by recording their electrical activity in much the same way that an electrocardiogram (EKG) monitors the heart. They say that the technique could revolutionize the way we test drugs and carry out environmental sensing. Using extremely sensitive equipment, the [...]
To understand the big picture, give it time — and sleep

Memorizing a series of facts is one thing, understanding the big picture is quite another. Now a new study demonstrates that relational memory — the ability to make logical “big picture” inferences from disparate pieces of information – is dependent on taking a break from studies and learning, and even more important, getting a good [...]

New Haven, Conn. — Yale School of Medicine and University of Crete School of Medicine researchers report in Cell April 20 the first evidence of a molecular mechanism that dynamically alters the strength of higher brain network connections. This discovery may help the development of drug therapies for the cognitive deficits of normal aging, and [...]
Omega-3 fatty acid may help prevent Alzheimer’s brain lesions

A type of omega-3 fatty acid may slow the growth of two brain lesions that are hallmarks of Alzheimer’s disease, UC Irvine scientists have discovered. The finding suggests that diets rich in docosahexaenoic acid (DHA) can help prevent the development of Alzheimer’s disease later in life. This study with genetically modified mice is the first [...]

A new category of drug has shown promising results for HIV/AIDS patients who failed to respond to other treatments, a study to be shows. Especially when combined with other medications, raltegravir — the first in a new class of anti-retroviral drugs called integrase inhibitors — dramatically reduced the presence of the HIV virus and boosted [...]

Link found between immune system and high plasma lipid levels
Posted by: Derya on: April 13, 2007
Researchers at the University of Chicago have found an unsuspected link between the immune system and high plasma lipid levels (cholesterol and triglycerides in the blood) in mice. The finding could lead to new ways to reduce the risk of heart disease by lowering elevated lipid levels.

Scientists have identified the most clear genetic link yet to obesity in the general population as part of a major study of diseases funded by the Wellcome Trust, the UK’s largest medical research charity. People with two copies of a particular gene variant have a 70% higher risk of being obese than those with no [...]

Much research has shown that reduced calorie intake can increase health and longevity. Professor Stephen Spindler (University of California) and his collaborators have discovered that reducing calorie intake later in life can still induce many of the health and longevity benefits of life-long calorie reduction. Importantly, this also includes anti-cancer effects. They are using this [...]

Will you lose weight and keep it off if you diet? No, probably not, UCLA researchers report in the April issue of American Psychologist, the journal of the American Psychological Association. “You can initially lose 5 to 10 percent of your weight on any number of diets, but then the weight comes back,” said Traci [...]

Flavonoids. You’ve heard of them — the good-for-your-health compounds found in plants that we enjoy in red wine, dark chocolate, green tea and citrus fruits. Mother Nature is an ace at making them, producing different ones by the thousands, but no chemist has figured out a good way to synthesize a special class of these [...]

New research from Columbia University Medical Center may explain why people who are able to easily and accurately recall historical dates or long-ago events, may have a harder time with word recall or remembering the day’s current events. They may have too much memory – making it harder to filter out information and increasing the [...]
