ANN ARBOR, Mich

.— Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes using a new manufacturing process.

The process is called “capillary forming,” and it takes advantage of capillary action, the phenomenon at work when liquids seem to defy gravity and spontaneously travel up a drinking straw.

The new miniature shapes have the potential to harness the exceptional mechanical, thermal, electrical, and chemical properties of carbon nanotubes in a scalable fashion, said A. John Hart, an assistant professor in the Department of Mechanical Engineering and in the School of Art & Design.

The 3D nanotube structures could enable countless new materials and microdevices, including probes that can interface with individual cells, novel microfluidic devices, and lightweight materials for aircraft and spacecraft. (more…)

It turns out that the undisputed king of the dinosaurs, Tyrannosaurus rex, didn’t just eat other dinosaurs but also each other. Paleontologists from the United States and Canada have found bite marks on the giants’ bones that were made by other T. rex, according to a new study published online Oct. 15 in the journal PLoS ONE.

While searching through dinosaur fossil collections for another study on dinosaur bones with mammal tooth marks, Yale researcher Nick Longrich discovered a bone with especially large gouges in them. Given the age and location of the fossil, the marks had to be made by T. rex, Longrich said. “They’re the kind of marks that any big carnivore could have made, but T. rex was the only big carnivore in western North America 65 million years ago.” (more…)

COLUMBIA, Mo. – For some women, the effects of breast cancer, the most common cancer affecting women, do not end when they leave the hospital. Now, researchers in the University of Missouri School of Health Professions have studied the lives of breast cancer patients following chemotherapy and found that their environments and available support systems help determine the quality of their lives.

“A lot of times people get mentally and emotionally ready to deal with chemotherapy and they receive a lot of support during that time,” said Stephanie Reid-Arndt, an assistant professor of health psychology in the School of Health Professions. “Then they go home and everyone feels like it’s over, but the patients still have worries and fears about the changes they’ve been through and what it means for the future.” (more…)
