Ancient Giant Turtle Fossil Revealed

Picture a turtle the size of a Smart car, with a shell large enough to double as a kiddie pool. Paleontologists from North Carolina State University have found just such a specimen – the fossilized remains of a 60-million-year-old South American giant that lived in what is now Colombia.

The turtle in question is Carbonemys cofrinii, which means “coal turtle,” and is part of a group of side-necked turtles known as pelomedusoides. The fossil was named Carbonemys because it was discovered in 2005 in a coal mine that was part of northern Colombia’s Cerrejon formation. The specimen’s skull measures 24 centimeters, roughly the size of a regulation NFL football. The shell which was recovered nearby – and is believed to belong to the same species – measures 172 centimeters, or about 5 feet 7 inches, long. That’s the same height as Edwin Cadena, the NC State doctoral student who discovered the fossil. (more…)

Tilting Cars on the Assembly Line: A New Angle on Protecting Autoworkers

COLUMBUS, Ohio – Letting autoworkers sit while they reach into a car’s interior could help prevent shoulder and back strain – but another solution might be to tilt the entire car so that workers can stand up.

That’s the finding of two recent studies, which tested two ways to protect autoworkers from injury.

Sitting on a cantilevered chair reduced the stress on the workers’ backs and shoulders for three common installation tasks. But a different strategy – tilting a car sideways on a carriage so that workers could access the interior while standing – reduced the stress for nine different tasks. (more…)

UCLA Researchers Map Damaged Connections in Phineas Gage’s Brain

Famous 1848 case of man who survived a terrible accident has modern parallel

Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, “smeared with blood and brains.”

Miraculously, Gage lived, becoming the most famous case in the history of neuroscience — not only because he survived a horrific accident that led to the destruction of much of his left frontal lobe but also because of the injury’s reported effects on his personality and behavior, which were said to be profound. Gage went from being an affable 25-year-old to one that was fitful, irreverent and profane. His friends and acquaintances said he was “no longer Gage.” (more…)

New ‘Brandon Generator’ Adventure Fueled by Espressos, HTML5

Internet Explorer launches the second episode of “The Random Adventures of Brandon Generator,” an interactive animated Web series created by luminaries from the film and comic worlds – with a big assist from the audience.

REDMOND, Wash. – May 17, 2012 – A blocked writer, haunted by the cursor blinking cruelly on his blank laptop screen, blacks out in the midst of an epic espresso binge. He awakes to find prose, sketches and story ideas on his Dictaphone – none of which he can remember creating. (more…)

Microbe That Can Handle Ionic Liquids

New Find From Joint BioEnergy Institute Could Help Reduce Biofuel Production Costs

In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing.

Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified a tropical rainforest microbe that can endure relatively high concentrations of an ionic liquid used to dissolve cellulosic biomass. The researchers have also determined how the microbe is able to do this, a discovery that holds broad implications beyond the production of advanced biofuels. (more…)

People with Paralysis Control Robotic Arms using Brain-Computer Interface

A new study in Nature reports that two people with tetraplegia were able to reach for and grasp objects in three-dimensional space using robotic arms that they controlled directly with brain activity. They used the BrainGate neural interface system, an investigational device currently being studied under an Investigational Device Exemption. One participant used the system to serve herself coffee for the first time since becoming paralyzed nearly 15 years ago.

PROVIDENCE, R.I. [Brown University] — On April 12, 2011, nearly 15 years after she became paralyzed and unable to speak, a woman controlled a robotic arm by thinking about moving her arm and hand to lift a bottle of coffee to her mouth and take a drink. That achievement is one of the advances in brain-computer interfaces, restorative neurotechnology, and assistive robot technology described in the May 17 edition of the journal Nature by the BrainGate2 collaboration of researchers at the Department of Veterans Affairs, Brown University, Massachusetts General Hospital, Harvard Medical School, and the German Aerospace Center (DLR).
