As students learn a new concept, measuring how well they grasp it has often depended on traditional paper and pencil tests. Dartmouth researchers have developed a machine learning algorithm, which can be used to measure how well a student understands a concept based on his or her brain activity patterns. The findings are published in Nature Communications.

Pressure difference and vortex flow of blood in heart chambers may signal heart dysfunction
Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to heart failure.

Scientists map huge undersea fresh-water aquifer off US Northeast
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

First-ever successful mind-controlled robotic arm without brain implants
A team of researchers from Carnegie Mellon University, in collaboration with the University of Minnesota, has made a breakthrough in the field of noninvasive robotic device control. Using a noninvasive brain-computer interface (BCI), researchers have developed the first-ever successful mind-controlled robotic arm exhibiting the ability to continuously track and follow a computer cursor.

Bacteria live on our eyeballs—and understanding their role could help treat common eye diseases
You may be familiar with the idea that your gut and skin are home to a collection of microbes—fungi, bacteria and viruses—that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they're called the eye microbiome. When these microbes are out of balance—too many or too few of certain types—eye diseases may emerge.

Algorithm quickly finds hidden objects in dense point clouds
A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.

This assistive robot is controlled via brain-computer interface
Researchers at the University of Cassino and Southern Lazio, in Italy, have recently developed a cutting-edge architecture that enables the operation of an assistive robot via a P300-based brain computer interface (BCI). This architecture, presented in a paper pre-published on arXiv, could finally allow people with severe motion disabilities to perform manipulation tasks, thus simplifying their lives.

Possible signal pathway in the fight against obesity-related fatty liver disease identified
A research group from the Medical University of Vienna reports how the hormone leptin stimulates the liver to export lipids and reduce the fat production in the liver. This occurs due to the activation of neurons in the brain stem. These findings provide new approaches for the fight against non-alcoholic fatty liver disease, which often occurs in connection with obesity. The results were just published in Nature Communications.

Engineers 3-D print flexible mesh for ankle and knee braces
Hearing aids, dental crowns, and limb prosthetics are some of the medical devices that can now be digitally designed and customized for individual patients, thanks to 3-D printing. However, these devices are typically designed to replace or support bones and other rigid parts of the body, and are often printed from solid, relatively inflexible material.

Skinflow: A soft robotic skin based on liquid transmission
Researchers at the Bristol Robotics Laboratory and the University of Bristol have recently developed a new soft robotic skin-like sensor that is based on fluidic transmission. This sensor, presented at the second IEEE International Conference on Soft Robotics (RoboSoft), could have interesting applications in a variety of fields, ranging from robotics to virtual reality (VR).
