Fossils Reveal Ancient Primates Had Claws, and Nails Too

Stony Brook University

New fossil evidence shows that ancient primates – including one of the oldest known, Teilhardina brandti – had specialized grooming claws as well as nails. The findings, published online in the Journal of Human Evolution, suggest the transition from claws to nails was more complex than previously thought.

Better Model of Water Under Extreme Conditions Could Aid Understanding of Earth's Mantle

University of Chicago

A team of University of Chicago scientists ran quantum simulations to develop a new model of the behavior of water at extremely high temperatures and pressures. The computational measurements, published June 18 in the Proceedings of the National Academy of Sciences, should help scientists understand water’s role in the makeup of the mantle and potentially in other planets.

Collaboration yields discovery of 12-sided silica cages

Cornell University

In a paper published in Nature, a team led by Uli Wiesner, the Spencer T. Olin Professor of Engineering in the Department of Materials Science and Engineering at Cornell University, reports discovery of 10-nanometer, individual, self-assembled dodecahedral structures – 12-sided silica cages that could have applications in mesoscale material assembly, as well as medical diagnosis and therapeutics.

Chameleon-Inspired Nanolaser Changes Colors

Northwestern University

• Chameleons change color by controlling the spacing among nanocrystals on their skin • Northwestern’s nanolaser changes color similarly — by controlling the spacing among metal nanoparticles • By stretching and releasing an elastic substrate, the nanoparticles move further apart or closer together to control color
