Reinforcement learning expedites 'tuning' of robotic prosthetics
Researchers have developed an intelligent system for 'tuning' powered prosthetic knees, allowing patients to walk comfortably with the prosthetic device in minutes, rather than the hours necessary if the device is tuned by a trained clinical practitioner. The system is the first to rely solely on reinforcement learning to tune the robotic prosthesis.

WPI computer scientist developing new technology to 'contain' hackers' attacks
With support from the National Science Foundation, a computer scientist at Worcester Polytechnic Institute (WPI) is developing a new technology to protect companies -- and computer users -- from malware attacks. Known as single-use services or 'containerization,' the technology aims to prevent an attack on a website from compromising other servers, data, and users. Instead of being given direct access to the webserver, each user interacts with a temporary copy that is destroyed when the session ends.

From emergence to eruption: Comprehensive model captures life of a solar flare
A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.

Simple rules predict and explain biological mutualism
Scientists have long employed relatively simple guidelines to help explain the physical world, from Newton's second law of motion to the laws of thermodynamics. Biomedical engineers at Duke University have used dynamic modeling and machine learning to construct similarly simple rules for complex biology. They have devised a framework to accurately interpret and predict the behavior of mutually beneficial biological systems, such as human gut bacteria, plants and pollinators, or algae and corals.

Water, not temperature, limits global forest growth as climate warms
The growth of forest trees all over the world is becoming more water-limited as the climate warms. The effect is most evident in northern climates and at high altitudes where the primary limitation on tree growth had been cold temperatures. The research, to be published in Science Advances this week, is the first time that changes in tree growth in response to current climate changes have been mapped at a near-global scale.

A new twist on a mesmerizing story
The Einstein-de Haas effect, first demonstrated more than a century ago, provides an intriguing link between magnetization and rotation in ferromagnetic materials. An international team led by ETH physicist Steven Johnson now established that the effect has also a central role in ultrafast processes that happen at the sub-picosecond timescale -- and thus deliver fresh insight into materials that might form the basis for novel devices.

Pore size influences nature of complex nanostructures

Herpes viruses and tumors evolved to learn how to manipulate the same ancient RNA
Herpes viral infections use the ancient genetic material found in the human genome to proliferate, mimicking the same process tumors have been found to manipulate, Mount Sinai researchers have shown for the first time. These observations provide further insight about how herpes viruses can manipulate the immune system in ways that may drive neurodegenerative diseases like Alzheimer's, according to the study, published in Nature Communications in January.
