University of Michigan scientists have used an insulin-like growth factor called IGF-I to stimulate growth of a myelin membrane sheath around neurons. Scientists believe understanding how growth factors affect neural development could lead to new treatments for neurodegenerative diseases like diabetic neuropathy, multiple sclerosis and amyotrophic lateral sclerosis (ALS).
Evidence is mounting that the sun's magnetic field looks more like a wild cyclone than a tidy lawn sprinkler---the image scientists had accepted for almost 40 years. The cyclone-like shape comes from a mathematical model first proposed last year by University of Michigan space scientist Len Fisk.
Researchers are gaining valuable insight into how Ebola uses glycoproteins to wreak its deadly havoc. Results from this study provide insight into the strategies that Ebola virus uses to evade detection and point to potential antiviral targets. The new findings may also have far-reaching benefits for fighting other illnesses.
Even though people of all ages are working fewer hours and retiring earlier than their parents and grandparents did, many of them feel overloaded. "Especially in two-job families with young children, life can seem like one long sprint, without time for real exercise or real leisure," says University of Michigan psychologist Robert L. Kahn.

The disorder strikes some 5,000 Americans, usually during their teen-age or young-adult years.
Consider the escape mechanism of the lowly tadpole. Sensing drought or a shrinking food supply in its home pond, the tadpole produces a hormone that accelerates its transformation into a toad or frog.
Imagine a milky white, peppermint-flavored liquid that, when added to a pool of water teeming with cholera, within minutes makes the water safe to drink. Imagine a cream that could be used like a sunscreen to protect a soldier from anthrax, botulinum, ricin and other toxins in the biological warfare arsenal. This may sound like science fiction, but these products may soon be used in humans, says University of Michigan Medical Center researcher

A nasal spray influenza vaccine pioneered by Hunein F. Maassab, professor of epidemiology at the University of Michigan School of Public Health, has proved 93 percent effective in a major study of 1,600 children across the country. The vaccine triggers an early, local antibody response in the nasal passages. Influenza kills 20,000 people each year in the United States alone.
Developed by research scientists in the University of Michigan College of Engineering's Mobile Robotics Laboratory, the GuideCane is a computerized, sonar-equipped navigation aid for the blind which detects obstacles in the user's path and automatically steers around them.
When continental plates come together to form mountain ranges, the impact from the collision bends microscopic grains in rocks more than 1,200 miles away. Evidence shows that seemingly quiet mid-continent areas are highly sensitive recorders of plate tectonic activity.
A collaboration between researchers at the University of Michigan Medical Center and the University of Kiel, Germany, has shed new light on the complex genetic roots of psoriasis---information which researchers believe will point the way to more effective treatments for the skin disease which afflicts 6 million Americans.
More studies show that hard core smokers may be using nicotine to manage depression, ADHD, anxiety or bulimia. People with these conditions or co-factors often use nicotine to help manage their symptoms. Treat the disorders first or simultaneously, says U-M study.

The U-M research could lead to a way to eliminate the threat of deafness to individuals treated with a common class of antibiotics.
The University of Michigan's Comprehensive Cancer Center is launching a statewide network of interactive computer kiosks to link residents with up-to-date health information. The $1 million project, was funded by proceeds from the state tobacco tax. The highly interactive system is the first health-related project of its kind in the nation.
Doctors can face an ethical dilemma when patients request screening tests - such as those for breast cancer and prostate cancer - that may be ill-advised under certain circumstances. Four authors explore that predicament in the article "Ethical Considerations in the Provision of Controversial Screening Tests," in the current issue of the Archives of Family Medicine.
