Paleontologists have discovered clues to the evolution of the biggest animals to ever walk on land by studying one of the tiniest members of the group ever found. (Credit: Andrey Atuchin) (Inside Science) — Sauropods were the largest animals that ever lived on land. These plant-eating dinosaurs could reach 120 feet in length, and yet their heads were small enough that you could hold its skull in your arms.

Tiny density changes in the crust of Ceres indicate that the dwarf planet’s pole has wandered over time. The path it took suggests a liquid ocean once sat beneath the surface. (Credit:NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/ASI/INAF) NASA’s Dawn mission has uncovered a wealth of information about the largest objects in our asteroid belt: Vesta and Ceres. Since its arrival at the latter in 2015, the spacecraft has revealed an active icy world full of surprises, one more of which has just ...read more

(Credit: Anton Gvozdikov/shutterstock) We see countless people everyday — in stores, in the gym, on television and during our commutes. But how many faces can we actually recognize? For the first time, a paper, published Wednesday (Oct. 10) in the Proceedings of the Royal Society B, has an answer: 5,000, more or less. That’s quite a jump from our evolutionary past. After all, the social circle of our foraging ancestors hovered around 100 to 250, meaning that’s how many faces ...read more

(Credit: tommasso79/Shutterstock) Scientists say they’ve finally found a gene implicated in erectile dysfunction, a discovery that could help illuminate how the condition occurs on the most basic level. The condition is widespread among older men — some estimates put it at 40 percent or higher for men over 40 — and it’s thought to be influenced by a range of factors. Poor body weight, cardiovascular health, a lack of exercise and many other things can all predispose men ...read more
