A new bone-like metal foam can ‘heal’ at room temperature

Penn Engineers have developed a way to repair metal at room temperature, rather than welding. They call their technique “healing” because of its similarity to the way bones heal, recruiting raw material and energy from an external source.

Study finds kittens bond with their human caregivers like babies do

Carlo Siracusa of the School of Veterinary Medicine advised readers to keep in mind that while babies and kittens are similar, they’re not analogous; scientific findings about one may not hold true for the other. “We should be open-minded about the idea that there are other variables [at play],” he said.

Researchers find no link between testosterone and a lack of cognitive empathy

New research by Gideon Nave of the Wharton School found that, contrary to past research, increased testosterone levels do not impair men’s ability to empathize. “We found that there is no evidence to support this effect of testosterone, but that doesn’t rule out any possible effects,” said Nave. “From what we know, though, it seems that if testosterone does have an influence, the effect is complex, not linear.”

Wheels, drones and Rescue Randy: DARPA robotics competition puts mine rescue to the test

A four-legged robot from the School of Engineering and Applied Science was among robots performing underwater search and rescue in a competition. “They're doing everything completely autonomously, so every step they take is kind of a minor victory for us,” said C. J. Taylor. “We always feel that we could do better. We learn so much from each of these events and that gives us new ideas about things that we want to try.”
