What Did T. Rex Eat? Each Other.

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…)

Women Fight the Effects of Chemotherapy Long After Treatment Ends, MU Researchers Find

Health

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…)

Argonne, ILL — For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size. Researchers will now be able to develop ways to control conditions under which they are grown. The breakthrough will affect a wide range of applications including solar-cell technology and chemical and biological sensors. The research is published in NANOLetters.

As coauthor Wenge Yang of the Carnegie Institution’s Geophysical Laboratory explained: “It’s been very difficult to watch these tiny particles be born and grow in the past because traditional techniques require that the sample be in a vacuum and many nanoparticles are grown in a metal-conducting liquid. So we have not been able to see how different conditions affect the particles, much less understand how we can tweak the conditions to get a desired effect.” (more…)
