Without adequate funding, deadly wheat disease could threaten global food supplies

MINNEAPOLIS / ST. PAUL (04/15/2013) -- Disease-resistant wheat developed over the past half century helped ensure steady world food supplies, but a global team led by researchers from the University of Minnesota warns in a new paper that without increased financial support for disease resistance research, new strains of a deadly fungal disease could leave millions without affordable access to food.

System allows multitasking runners to read on a treadmill

WEST LAFAYETTE, Ind. - A new innovation allows treadmill users to work their bodies and brains at the same time.

The system, called ReadingMate, adjusts text on a monitor to counteract the bobbing motion of a runner's head so that the text appears still, said Ji Soo Yi, an assistant professor of industrial engineering at Purdue University.

Research sheds new light on traumatic brain injuries

LEXINGTON, Ky. (April 15, 2013) — Even a mild injury to the brain can have long lasting consequences, including increased risk of cognitive impairment later in life. While it is not yet known how brain injury increases risk for dementia, there are indications that chronic, long-lasting, inflammation in the brain may be important. A new paper by researchers at the University of Kentucky Sanders-Brown Center on Aging (SBCoA), appearing in the Journal of Neuroscience, offers the latest information concerning a "switch" that turns "on" and "off" inflammation in the brain after trauma.

Researchers untangle molecular pathology of giant axonal neuropathy

Giant axonal neuropathy (GAN) is a rare genetic disorder that causes central and peripheral nervous system dysfunction. GAN is known to be caused by mutations in the gigaxonin gene and is characterized by tangling and aggregation of neural projections, but the mechanistic link between the genetic mutation and the effects on neurons is unclear.

Taste of beer, without effect from alcohol, triggers dopamine release in the brain

INDIANAPOLIS -- The taste of beer, without any effect from alcohol itself, can trigger dopamine release in the brain, which is associated with drinking and other drugs of abuse, according to Indiana University School of Medicine researchers.

NYU researchers offer 12 principles for effective contraceptive counseling

New research by Professor James Jaccard, Ph.D., and Nicole Levitz, M.P.H., of the New York University Silver School of Social Work and its Center for Latino Adolescent and Family Health (CLAFH) has led them to suggest 12 evidence-based principles that can be used to improve contraceptive counseling of adolescents in U.S. health care clinics, doctor's offices, and health service organizations.

Musicians who learn a new melody demonstrate enhanced skill after a night's sleep

A new study that examined how the brain learns and retains motor skills provides insight into musical skill.

Performance of a musical task improved among pianists whose practice of a new melody was followed by a night of sleep, says researcher Sarah E. Allen, Southern Methodist University, Dallas.

The study is among the first to look at whether sleep enhances the learning process for musicians practicing a new piano melody.

Stanford researchers turn skin cells directly into the cells that insulate neurons

STANFORD, Calif. — Researchers at the Stanford University School of Medicine have succeeded in transforming skin cells directly into oligodendrocyte precursor cells, the cells that wrap nerve cells in the insulating myelin sheaths that help nerve signals propagate.

Vitamin D may reduce risk of uterine fibroids, according to NIH study

Women who had sufficient amounts of vitamin D were 32 percent less likely to develop fibroids than women with insufficient vitamin D, according to a study from researchers at the National Institutes of Health.

Fibroids, also known as uterine leiomyomata, are noncancerous tumors of the uterus. Fibroids often result in pain and bleeding in premenopausal women, and are the leading cause of hysterectomy in the United States.

Gene sequencing project finds new mutations to blame for a majority of brain tumor subtype

The St. Jude Children's Research Hospital – Washington University Pediatric Cancer Genome Project has identified mutations responsible for more than half of a subtype of childhood brain tumor that takes a high toll on patients. Researchers also found evidence the tumors are susceptible to drugs already in development.

Ordinary skin cells morphed into functional brain cells

Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.

This discovery appears today in the journal Nature Biotechnology.

Freezing nerves knocks pain out cold

NEW ORLEANS (April 14, 2013)—Using a tiny ball of ice, a minimally invasive interventional radiology treatment called cryoneurolysis safely short circuits chronic pain caused by nerve damage, according to data being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.

Reactivating memories during sleep

EVANSTON, Ill. --- Why do some memories last a lifetime while others disappear quickly?

A new study suggests that memories rehearsed, during either sleep or waking, can have an impact on memory consolidation and on what is remembered later.

The new Northwestern University study shows that when the information that makes up a memory has a high value (associated with, for example, making more money), the memory is more likely to be rehearsed and consolidated during sleep and, thus, be remembered later.

'Seeing' the flavor of foods

NEW ORLEANS, April 11, 2013 — The eyes sometimes have it, beating out the tongue, nose and brain in the emotional and biochemical balloting that determines the taste and allure of food, a scientist said here today. Speaking at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, he described how people sometimes "see" flavors in foods and beverages before actually tasting them.

Revealing the scientific secrets of why people can't stop after eating one potato chip

NEW ORLEANS, April 11, 2013 —The scientific secrets underpinning that awful reality about potato chips — eat one and you're apt to scarf 'em all down — began coming out of the bag today in research presented at the 245th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society. The meeting, which news media have termed "The World Series of Science," features almost 12,000 presentations on new discoveries and other topics. It continues here through today.
