“Scientists thought these were dead galaxies that had finished making stars a long time ago,” U-M researcher Alyson Ford said. “But we’ve shown that they are still alive and are forming stars at a fairly low level.”

When Michael Jonas learned he was HIV positive, he returned from Florida to his home in Jackson, Mich., to die. That was a decade ago, but Jonas is still alive, taking antiviral drugs and planning his future.

The exercise led to lasting improve- ments in the ability to reason and solve new problems.

Runners: ready to get back on the road, or build up for a race? U-M women’s cross country coach Mike McGuire offers tips for faster, safer recreational running.

It’s allergy season. Doctors from the Michigan Sinus Center offer tips for keeping your symptoms in check.

The hottest stars in the universe spin so fast that they get a bit squished at their poles and dimmer around their middle. A 90-year-old theory predicts the extent of this phenomenon—but a new U-M study shows that theory has major flaws. “It is surprising to me that von Zeipel’s law has been adopted in astronomy for such a long time,” says researcher Xiao Che.

Older adults don’t have to accept the loss of strength and muscle. Even people in their 70s and 80s can build “significant strength improvement” with simple exercises.

In a surprise discovery that overturns a century-old tenet of physics, U-M professor Stephen Rand and his team found that a light field can generate magnetic effects that are 100 million times stronger than previously expected. The discovery could lead to a revolution in solar power.

The blitzkrieg advance of two closely related species of mussels—the zebra and quagga—is stripping the lakes of their life-supporting algae, resulting in a remarkable ecological transformation and threatening the multibillion-dollar U.S. commercial and recreational Great Lakes fisheries.
