A new dinosaur named Brontomerus mcintoshi, 'thunder-thighs' to its discoverers because of its powerful thigh muscles, has been described in a paper in the journal Acta Palaeontologica Polonica. 

A member of the long-necked sauropod group of dinosaurs which includes Diplodocus and Brachiosaurus, Brontomerus may have used its powerful thighs as a weapon to kick predators, or less interestingly, to help travel over rough terrain. Brontomerus lived about 110 million years ago, during the Early Cretaceous Period, and probably had to contend with fierce raptors such as Deinonychus and Utahraptor.

Patients with Hutchinson-Gilford Progeria Syndrome age eight to 10 times faster than the rest of us and rarely live beyond 13 years. Almost all of the patients die from complications of arteriosclerosis, the clogging or hardening of arteries or blood vessels caused by plaques, which leads to heart attack and stroke.

Research on Progeria is difficult because the disease is exceedingly rare and only 64 children living with progeria are known, making access to patients very difficult.

Think all Republicans are anti-science or religious people are stupid?  You may look for data to rationalize your bias but a new study in Psychological Science says it may just be your own low self-esteem; when people are feeling badly about themselves, they're more likely to show bias against people who are different from them. 

Jeffrey Sherman of the University of California, Davis, who wrote the study with Thomas Allen, used the Implicit Association Test (IAT), a task designed to assess people's automatic reactions to words and/or images, to investigate this claim.

Supernova remnant Cassiopeia A (Cas A) is the remains of a massive star 11,000 light years away that would have appeared to explode about 330 years ago as observed from Earth.

Neutron stars like Cas A contain the densest known matter that is directly observable. One teaspoon of neutron star material weighs six billion tons. The pressure in the star's core is so high that most of the charged particles, electrons and protons, merge resulting in a star composed mostly of uncharged particles called neutrons.

Concerns about geomagnetic storms are all the rage this week, so what are they? A geomagnetic storm is a disturbance in the magnetosphere due to near-Earth space weather that happens when the interplanetary magnetic field turns southward and remains that way.

A new study accepted for publication in Chemical Geology says deep saline groundwaters in South Africa's Witwatersrand Basin may have remained isolated for perhaps millions of years.

The Witwatersrand Basin covers approximately 400 kilometers, some of which is subcrop of the Witwatersrand Supergroup sedimentary and sub-ordinate volcanic sequences and is well-known for tourist expeditions to search for gold.

The researchers found the noble gas neon dissolved in water in three-kilometer deep crevices and the unusual neon profile, along with the high salinities and some other unique chemical signatures, is very different from anything seen in molten fluid and gases rising from beneath the Earth's crust.
