Brain Connections Break Down as We Age

ANN ARBOR, Mich.—It’s unavoidable: breakdowns in brain connections slow down our physical response times as we age, a new study suggests.

This slower reactivity is associated with an age-related breakdown in the corpus callosum, a part of the brain that acts as a dam during one-sided motor activities to prevent unwanted connectivity, or cross-talk, between the two halves of the brain, said Rachael Seidler, associate professor in the University of Michigan School of Kinesiology and Department of Psychology, and lead study author.

ANN ARBOR, Mich. — Sharon Herbert and her team were wrapping up their dig at the Tel Kedesh site in Israel, sweeping the site in the 140-degree heat, when a student showed University of Michigan doctoral instructor Lisa Cakmak what he first thought was a gold candy wrapper.

ANN ARBOR, Mich.—Pilots and dentists have more in common than one might think: Both jobs are highly technical and require teamwork. Both are subject to human error where small, individual mistakes may lead to catastrophe if not addressed early.

Photo Proof: Super Stars of the Universe Have Humble Beginnings

ANN ARBOR, Mich.—The first close-up picture of a nascent super massive star and its surroundings has shown that the highest mass stars in the universe form just like their smaller counterparts. They are born from swirling disks of gas and dust, rather than from violent stellar collisions.

“How these high mass stars form has been a debate for 20 years,” said Stefan Kraus, a research fellow in the University of Michigan Department of Astronomy who is first author of a paper on the findings published July 15 in Nature.

ANN ARBOR, Mich.—Dostoyevsky and Tolstoy portrayed Russians as a brooding, complicated people, and ethnographers have confirmed that Russians tend to focus on dark feelings and memories more than Westerners do.

But a new University of Michigan study finds that even though Russians tend to brood, they are less likely than Americans to feel as depressed as a result.
