Before Dinosaurs, Carolina Butcher was Top Beast of Prey

March 20, 2015 10:26 am | by North Carolina State University | News | Comments

A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. The "Carolina Butcher" was a nine-foot-long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems, such as armored reptiles and early mammal relatives.

This year’s Submarine Cable Map pays tribute to pioneering mapmakers of the Age of Discovery, incorporating elements of medieval and renaissance cartography. In addition to serving as navigational aids, maps from this era were works of art, often adorned with fanciful illustrations of real and imagined dangers. TeleGeography’s 2015 map brings back the lost design aesthetic to provide a view of the network through the lens of a bygone era.

Simulating a Perfectly Animated Smoke Cloud

The attack takes place at the climax of the blockbuster Avatar: Rockets slam into the Pandora inhabitants’ homeland tree. Explosions, flames and thick clouds of smoke appear on the screen. To keep the audience pinned to the edge of their seats, the images must be realistic. But the simulation of physical processes is especially tough to implement. This includes representation of liquids and gasses, which fall into the category of fluids.

Hunt for Alien Life: Do Hot Springs Bubble beneath the Ice of Saturn Moon?

March 12, 2015 2:44 pm | by Alicia Chang, AP Science Writer | News | Comments

New research suggests there are hot springs bubbling beneath the icy surface of a tiny Saturn moon. If confirmed, it would make the moon Enceladus (ehn-SEHL'-uh-duhs) the only other known body in the solar system besides Earth where hot water and rocks interact underground. That activity would make the moon an even more attractive place in the hunt for microbial life.

Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline. However, more recent findings, including a new study from neuroscientists at MIT and Massachusetts General Hospital (MGH), suggest that the real picture is much more complex.

Cloudy, with a High of 1,700 Kelvins: Analyzing Clouds around Exoplanets

Meteorologists sometimes struggle to accurately predict the weather here on Earth, but now we can find out how cloudy it is on planets outside our solar system. MIT Researchers describe a technique that analyzes data from NASA’s Kepler space observatory to determine the types of clouds on planets that orbit other stars. Their models indicate that the clouds on Kepler-7b are most likely made from liquid rock.

Predicting Human Crowds with Statistical Physics

For the first time, researchers have directly measured a general law of how pedestrians interact in a crowd. This law can be used to create realistic crowds in virtual reality games and to make public spaces safer. People intuitively know how to navigate through crowds in a way that both minimizes distance traveled and avoids collisions. But the 'force' that governs human interactions has been previously unknown.

During the second half of the 21st century, the U.S. Southwest and Great Plains will face persistent drought worse than anything seen in times ancient or modern, with the drying conditions “driven primarily” by human-induced global warming, a new study predicts. The research says the drying would surpass in severity any of the decades-long “megadroughts” that occurred much earlier during the past 1,000 years.

Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari and Guarneri — master violinmaking families from the 17th and 18th centuries who produced increasingly powerful instruments in the renaissance and baroque musical eras. These violins, worth millions of dollars today, represent the Cremonese period — what is now considered the golden age of violinmaking.

Explorations of Mathematical Models in Biology with Maple

February 10, 2015 9:29 am | by John A. Wass, Ph.D. | Articles | Comments

The author of this wonderful text delivers a brief, easy-to-absorb, yet very comprehensive text on modeling real-world data with Maple. Maple is software for performing mathematics, with a none-too-steep learning curve. In the introduction, the author is quick to point out that this is neither a detailed textbook of mathematical modeling, nor Maple. It is, however, a very well-written manual of introductory modeling and use of Maple.
