Virtual human body models supplement crash-test dummies

Countless people die every year in road accidents. To improve the safety of vehicle occupants, it has been customary for decades to carry out crash-tests using dummies. These crash-test dummies are increasingly getting virtual support in the form of computer models that simulate the defensive behavior of humans before a collision. Researchers at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI are among those using virtual human-body models in crash simulations, which yield more realistic conclusions about the injury risk. In their calculations, the researchers focus especially on muscle stiffness, which has not been taken into account in previous investigations.

Scientists discover evolutionary link to modern-day sea echinoderms

Scientists at The Ohio State University have discovered a new species that lived more than 500 million years ago—a form of ancient echinoderm that was ancestral to modern-day groups such as sea cucumbers, sea urchins, sea stars, brittle stars and crinoids. The fossil shows a crucial evolutionary step by echinoderms that parallels the most important ecological change to have taken place in marine sediments.

A team of researchers at Johns Hopkins School of Medicine has developed a gel that, when injected into test animals, allowed new soft tissue to grow—replacing lost tissue. In their paper published in the journal Science Translational Medicine, the group describes their work developing the gel and how well it worked in test rats and rabbits.

A genomic tour-de-force reveals the last 5,000 years of horse history

Each year on the first Saturday in May, Thoroughbred horses reach speeds of over 40 miles per hour as they compete to win the Kentucky Derby. But the domestic horse wasn't always bred for speed. In fact, an international team now has evidence to suggest that the modern horse is genetically quite different from the horses of even just a few hundred years ago.
