When the brain, not the ears, goes hard of hearing
...searchers are discussing the results so far of the hunt for genes that play a role in the aging brain's plummeting ability to organize the information our ears record. "Traditionally, scientists studying hearing problems started looking at the ear," says Robert D. Frisina, Ph.D., professor of Otolaryngol...Early learning leaves lasting changes in brain, Stanford owl study shows
... owl then uses that map to know precisely where to hunt for dinner. In his work, Knudsen and graduate student Brie Linkenhoker put glasses on the owls that shift the world to one side. When the owl first peers through the new specs, a squeaking mouse located off to the side appears to be straight ahead. T...Marine sponge leads researchers to immune system regulator

Finding the natural activator -- what immunologist call the endogenous ligand -- for these cells is crucial to understanding their biology, he added, and might provide a gentler and more enduring ...Molecular clock genes influence metabolism of sugar and dietary fats
...oved from eating our fill at one sitting after the hunt to continuous availability of fast food. Nutritionists have long speculated that it might matter whether we "nibble" or "gorge" our calories, and that this makes a difference in how our bodies handle a high-fat diet.

...logy - in which no single gene is suspected in the hunt for causality - the researchers compared extracted RNA, a product of genes, from diseased tissue samples with RNA from normal tissue. The researchers then used a specially designed gene chip that allows for bulk testing of more than 10,000 genes, a ...Tumor suppressor gene family may be key to new colon cancer drugs
In the hunt for new cancer drug targets, scientists from the Johns Hopkins Kimmel Cancer Center and the Howard Hughes Medical Institute have discovered mutations in a family of genes linked to more than a quarter of colon cancers, as well as several other common...Cancer markers news backgrounder: Future of cancer diagnosis, treatment lies in tumor 'barcode'
...even preventable, disease is everyone's hope. The hunt is on at The University of Texas M. D. Anderson Cancer Center to find such "markers" of cancer a barcode of proteins or genes that identifies cells that have turned cancerous and gives hints as to how a patient's unique tumor can be treated. These b...UCSD researchers identify chromosome location for 2nd form of Joubert syndrome
...ssical symptoms associated with the disorder. "The hunt for genes for this syndrome has been extremely slow and none are currently known, due to the rarity of the syndrome," said the study's senior author, Joseph Gleeson, M.D., UCSD assistant professor of neurosciences.
