Technique Reveals the Basis for Machine-Learning Systems' Decisions

Oct. 28, 2016 — In recent years, the best-performing systems in artificial-intelligence research have come courtesy of neural networks, which look for patterns in training data that yield useful predictions or ... read more

A Tiny Machine: Infinitesimal Computing Device

Oct. 28, 2016 — Electrical and computer engineers have developed a design for a functional nanoscale computing device. The concept involves a dense, three-dimensional circuit operating on an unconventional type of ... read more

Oct. 28, 2016 — Children diagnosed with autism spectrum disorder (ASD) have greater numbers of harmful mutations in their mitochondrial DNA than family members, researchers ... read more

Oct. 28, 2016 — Scientists have begun to account for the topsy-turvy carbon cycle of the Colorado River delta – once a massive green estuary of grassland, marshes and cottonwood, now desiccated dead ... read more

Oct. 28, 2016 — Plasma turbulence, the wildly fluctuating pattern of particle motion, is a concern for fusion energy devices because it allows heat to escape the plasma. However, an even more serious concern is ... read more

Oct. 28, 2016 — Researchers have demonstrated improved control over and understanding of implosions in a Z-pinch, a particular type of magneto-inertial device that relies on the Lorentz force to compress plasma to ... read more

Oct. 28, 2016 — A new kind of gamma ray camera has been invented that can image beams of energetic electrons inside ultra-hot fusion plasma, report ... read more

Oct. 28, 2016 — An important new tool has been created for controlling fusion plasmas that are hotter than the sun. Changing the way the current system operates is a significant effort, considering the size and ... read more

Oct. 28, 2016 — The tokamak is an experimental chamber that holds a gas of energetic charged particles, plasma, for developing energy production from nuclear fusion. Most large tokamaks create the plasma with ... read more

Oct. 28, 2016 — Plasmas in fusion-energy producing devices are gases heated to millions of degrees that can carry millions of amperes of current. These superhot plasmas must be kept away from material surfaces of ... read more

Oct. 28, 2016 — For the first time, researchers have directly measured the complicated 3D patterns of flowing plasma as it strikes the walls of fusion and space propulsion ... read more

Oct. 28, 2016 — Going hungry at an early age can cause lifelong health problems. But the extent of malnutrition's damage depends on mom's diet too -- at least in worms. A new study of the tiny nematode ... read more

Early Pacific Seafarers Likely Latched Onto El Nino, Other Climate Patterns

Oct. 28, 2016 — Researchers employed computer simulations and climatic data to help them explore the travels that led to the settlement of islands in Remote ... read more

Oct. 28, 2016 — Iron is an essential nutrient for biological productivity in the oceans. However, dissolved iron quickly combines with oxygen and is then no longer usable by organisms. For a long time it has been a ... read more

New Biochar Model Scrubs Carbon Dioxide from the Atmosphere

Oct. 28, 2016 — An economically viable model to scrub carbon dioxide from the atmosphere has been developed to thwart runaway, point-of-no-return global warming. The researchers propose using a “bioenergy-biochar ... read more

What's the Best Way to Match the Implant to the Breast?

Oct. 28, 2016 — How should plastic surgeons choose the best implant type and size for women undergoing breast augmentation surgery? Implant size selection systems based on breast tissue measurements may provide ... read more

Oct. 28, 2016 — New surface materials that are extremely difficult to wet both by water and oil have now been developed by scientists. Because they don't need isolating air to stay trapped between the droplet ... read more

Oct. 28, 2016 — In mammals, three types of adipose tissues exist. White adipocytes are mainly located in the abdominal and subcutaneous areas of the body and highly adapted to store excess energy. Conversely, beige ... read more

Screws That Fit the Body's Notches

Oct. 28, 2016 — Complex bone fractures are often set with titanium or steel screws and plates. However, if these remain in the body for some time, they can cause health problems. A new bioceramic screw nail has the ... read more
