Through the cycads and gingkoes of the floodplains, not far from the Sundance Sea, strode the 50-foot-long Suuwassea, a plant-eating dinosaur with a whip-like tail and an anomalous second hole in its skull destined to puzzle paleontologists in 150 million years. According to researchers at the University of Pennsylvania, Suuwassea emilieae (pronounced SOO-oo-WAH-see-uh eh-MEE-LEE-aye) is a smaller relative of Diplodocus and Apatosaurus and is the first named sauropod dinosaur from the Jurassic of southern Montana. Their findings currently appear in the journal Acta Paleontologica Polonica
"Suuwassea is the first unequivocal new sauropod from the Morrison Formation a 150-million-year-old geological formation extending from New Mexico to Montana in more than a century. It has a number of distinguishing features, but the most striking is this second hole in its skull, a feature we have never seen before in a North American dinosaur," said Peter Dodson, senior author and professor of anatomy at Penn School of Veterinary Medicine and professor in the Department of Earth and Environmental Sciences. "While its Diplodocus relatives have a single hole on the top of the skull related to the nasal cavity, paleontologists have yet to come up with a plausible use for this second hole."
The name Suuwassea comes from the Native American Crow word meaning "ancient thunder" and also a nod to "thunder lizard," the original nickname of the dinosaur now known as Apatosaurus. Emilieae is a reference to the late Emilie deHellebranth, whose financial support funded the dinosaur excavation.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
