Cosmologists Prove Negative Mass Can Exist In Our Universe
Astrophysicists have always thought negative mass requires exotic physics that would be impossible in our cosmos. They were wrong.
Negative mass is the hypothetical idea that matter can exist with mass of the opposite sign to the ordinary stuff. Instead of 2 kg, a lump of negative mass would be -2 kg.
Nobody knows whether negative mass can exist but there have nevertheless been plenty of analyses to determine its properties. In particular, physicists have investigated whether negative mass would violate various laws of the universe, such as the conservation of energy or momentum and therefore cannot exist. These analyses suggest that although the interaction of positive and negative mass produces counterintuitive behaviour, it does not violate these conservation laws.

Wolves Might Use Their Eyes to Talk to Each Other
It’s no secret that wolves, foxes, and dogs are highly social animals. But beyond all the wagging, pawing and yipping we like to try to interpret, canids may have yet another way to communicate. New research hints at the possibility that dogs and their ilk could be sending each other signals with their eyes.
A team of Japanese researchers looked at pictures of nearly every canid species and found that those with highly social pack and hunting behaviors were more likely to have easily-visible eyes. They then watched some of those species interact in zoos and concluded that those with eyes that were easier to see were more likely to be social. The results were published in a study in PLoS One on June 11.
“What this study shows is that there’s a correlation between facial markings and sociality and the need to communicate,” said zoologist Patricia McConnell of the University of Wisconsin-Madison, a dog behavior researcher who was not involved in the study.
The scientists organized 25 different wild canid species according to their facial features (using around a dozen photos of individuals from each species) into three groups and then looked to previous research to characterize the social behavior of each group.

Asteroid Vesta to reshape theories of planet formation
EPFL researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings, published today in Nature, question contemporary models of rocky planet formation, including that of Earth.
With its 500 km diameter, the asteroid Vesta is one of the largest known planet embryos. It came into existence at the same time as the Solar System. Spurring scientific interest, NASA sent the Dawn spacecraft into Vesta’s orbit for one year between July 2011 and July 2012.
