Web Use Gives Brain a Boost

For middle-aged, regular Internet surfing is better than reading a book: study

(Newser) - Sudoku not your thing? Web surfing may help boost brain power and prevent brain shrinkage in middle-aged and older people in a way that reading books cannot, the BBC reports. By studying the brain scans of volunteers aged 55 to 76, researchers found that experienced internet users show enhanced activity...

Chemistry Nobel Goes to 3 Who Found Glowing Protein

Compound vital to Alzheimer's research

(Newser) - The Nobel Prize in chemistry was awarded today to three scientists who discovered green fluorescent protein, a compound that allows biochemists to study cellular processes. The glowing protein, first found in jellyfish more than 40 years ago, can be attached to other structures and has been critical in research on...

For a Lifelong Healthy Diet, Look to the Mediterranean

Diet is healthy and satisfying, doctors say

(Newser) - A Mediterranean getaway may be too expensive these days, but a taste of the region is just what the doctor ordered. The most thorough study to date of the Mediterranean diet confirms long-held beliefs about its health benefits, writes Dr. Peter Libby in the New York Times. It’s “...

Genome Project Is a Bust: Expert

$3B effort to pinpoint disease-causing genes too broad, Duke doc says

(Newser) - The idea behind mapping the human genome (and spending $3 billion to do so) was to uncover common gene variants that cause disease. But a Duke University geneticist says that natural selection has worked better than we thought, that there are no common variants but rather a multitude of rare...

Low B12 Levels Tied to Brain Shrinkage, Memory Loss

Many adults deficient in crucial nutrient

(Newser) - Vitamin B12 deficiency can cause memory loss, particularly in the elderly, reports the BBC. People short on the nutrient were 6 times more likely than individuals with normal levels to experience brain shrinkage, which is strongly linked to dementia, a new study shows. Forty percent of people are believed to...

Brain Doesn't Remember Events—It Relives Them

Study records evidence supporting long-suspected memory pathway

(Newser) - Scientists for the first time have observed how brain cells drum up a memory, and the findings buttress the notion that our minds don't so much remember events as relive them.

Australian study shows exercise improves 'flawed memory'

(Newser) - A little sweatin' to the oldies might help oldsters with mild memory problems, an Australian study suggests.

Scientists Tinker With Biological Clock

New discovery on engineered liver genes could slow aging

(Newser) - US researchers believe they have found a way to turn back the clock on the processes which make organs age.

From diet to depression, here's what to watch

(Newser) - New research suggests our lifestyle choices affect memory loss almost as much as aging. Forbes looks at 10 surprising factors, positive and negative, that determine how sharp you'll stay:  
  1. Tofu—eating too much can increase dementia in the elderly.
  1. Carbs—likewise, too many derail Alzheimer's-fighting enzymes in the brain.

New Drug Twice as Effective Against Alzheimer's: Study

Treatment breaks apart protein clusters in brain cells of patients with disease

(Newser) - A new treatment could slow Alzheimer’s patients’ mental decline twice as fast as current drugs, the Chicago Tribune reports.
