	Myanmar farmers reap rewards from 3D printing Whizzing across a blue-lit platform with a whirr and a squeak, liquid plastic emanating from its chrome tip, the 3D printer seems a far cry from the muddy, crop-filled fields that fringe Yangon.
	World's first vertically stacked gate-all-around Si nanowire CMOS transistors At this week's IEEE IEDM conference, world-leading research and innovation hub for nano-electronics and digital technology, imec, reported for the first time the CMOS integration of vertically stacked gate-all-around (GAA) silicon nanowire MOSFETs. Key in the integration scheme is a dual-work-function metal gate enabling matched threshold voltages for the n- and p-type devices. Also, the impact of the new architecture on intrinsic ESD performance was studied, and an ESD protection diode is proposed. These breakthrough results advance the development of GAA nanowire MOSFETs, which promise to succeed FinFETs in future technology nodes.
	3-D-compatible germanium nMOS gate stack with high mobility and superior reliability International Electron Devices Meeting 2016 (IEDM) - Dec. 7, 2016 - At this week's IEEE IEDM conference, imec, the world-leading research and innovation hub in nano-electronics and digital technologies showed for the first time a silicon (Si)-passivated germanium (Ge) nMOS gate stack with dramatically reduced interface defect density (DIT) reaching the same level as a Si gate stack and with high mobility and reduced positive bias temperature instability (PBTI). These promising results pave the way to Ge-based finFETs and gate all-around devices, as promising options for 5nm and beyond logic devices.

	Stability challenge in perovskite solar cell technology While solar cell technology is currently being used by many industrial and government entities, it remains prohibitively expensive to many individuals who would like to utilize it.. There is a need for cheaper, more efficient solar cells than the traditional silicon solar cells so that more people may have access to this technology. One of the current popular topics in photovoltaic technology research centers around the use of organic-inorganic halide perovskites as solar cells because of the high power conversion efficiency and the low-cost fabrication.
	Eye tracking technology to assist navigation and other applications Pedestrians often try to find their way about using their smartphones. The computer scientist Peter Kiefer and the geomatics expert Martin Raubal are at work together trying to make things easier for them. They work at the GeoGazeLab at ETH Zurich and are trying to refine smartphone maps so that pedestrians will find their way perfectly in any new environment. To this end they are developing special systems that involve attaching an eye-tracking module to one's head. These modules comprise different cameras that are variously focussed on the eyes of the user and on the user's field of vision. By means of eye tracking, Kiefer and Raubal can determine which landmarks pedestrians use to orient themselves. Their findings are interesting. "People ignore some elements on the map completely", says Raubal. In order not to confuse people, he suggests that these elements – railway tracks, for example – should be left off such maps altogether.
	Keeping tabs on aging power cables to prevent outages Switzerland's power grid comprises over 250,000 kilometers of lines. Composed of a transmission and a distribution network, the voltage is gradually reduced from 380,000 to 230 volts enroute to the consumer. The aboveground transmission network, some sections of which are more than 40 years old, measures 6,700 kilometers. As it is designed for considerably smaller amounts of electricity from predominantly central power stations, it only partially satisfies today's needs. Nowadays, considerably larger quantities of electricity are transported, and an increasing number of decentralized (small-scale) power stations feed electricity obtained from renewable energy into the grid. The power lines are, therefore, becoming increasingly overloaded and getting hotter and hotter. As Switzerland's overhead high-voltage power lines are almost exclusively made of aluminum alloy while those in neighboring countries are usually composed of pure aluminum and a steel core as interconductors, international research results can only be applied to local conditions to a limited extent. In other words, national research is necessary.

In clinching third place, the shoe-box sized roadster edged out nearly 40 of the best teams from around the world.
Turkey briefly restricts internet after release of IS video Turkey restricted access to social media websites for several hours after the Islamic State group released a video purportedly showing two Turkish soldiers being burned alive, as Turkish warplanes on Friday pounded the extremist-held town in Syria near where the soldiers are believed to have gone missing.
Fractional disturbance observers could help machines stay on track Roads are paved with obstacles than can interfere with our driving. They can be as easy to avoid or adjust to as far-away debris or as hard to anticipate as strong gusts of wind. As self-driving cars and other autonomous vehicles become a reality, how can researchers make sure these systems remain in control under highly uncertain conditions? A team of automation experts may have found a way. Using a branch of mathematics called fractional calculus, the researchers created algorithmic disturbance observers that make on-the-fly calculations to put a disturbed system back on track.
Fractional calculus helps control systems hit their mark If you've ever searched for ways to curb your car's gas-guzzling appetite, you've probably heard that running on cruise control can help reduce your trips to the pump. How? Cars, it turns out, are much better than people at following what control systems experts call a setpoint—in this case, a set speed across varying terrain. Calling upon a branch of mathematics known as fractional calculus, a team of researchers has developed a new setpoint-tracking strategy that can improve the response time and stability of automated systems—and not just those found in your car.
Small wind turbines—a glimmer of hope for Poland's wind energy sector? A new Polish law imposing rules for the installation of wind turbines is likely to limit the development of renewables in the country, which continues to focus on its main energy source, coal. However, small wind turbines, which fall outside the scope of the recent measures, could represent a loophole for the wind energy sector
	Multi-core processors for mobility and industry 4.0 Safety-critical applications in automobility, aviation, and industry 4.0 will require far more digital computation capacity in the future.

The results are published online in the Annals of Surgery.
	Researchers analyze chess behavior Chess is one of the oldest—and most popular—board games. On Christmas Eve, the classic game is given as a gift several hundred thousand times over, whether as a chess set, computer game, or chess computer. Yet what is the secret of successful chess players? Cognitive scientists at the Cluster of Excellence Cognitive Interaction Technology (CITEC) at Bielefeld University have been investigating this question for the past year in the project "Ceege" by recording players' eye movements and facial expressions. Now, the researchers are revealing their preliminary results and explain why Norwegian grandmaster Magnus Carlsen again earned the title of world chess champion at this year's tournament.
	Protein that activates immune response harms body's ability to fight HIV In findings they call counterintuitive, a team of UCLA-led researchers suggests that blocking a protein, which is crucial to initiating the immune response against viral infections, may actually help combat HIV.
Research aids discovery of genetic immune disorder Investigators at the National Institutes of Health (NIH) and international colleagues have identified a genetic immune disorder characterized by increased susceptibility and poor immune control of Epstein-Barr virus (EBV) and, in some cases, an EBV-associated cancer called Hodgkin's lymphoma. The researchers studied two unrelated sets of siblings with similar immune problems and determined their symptoms were likely caused by a lack of CD70, a protein found on the surface of several types of immune cells. Scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH, conducted the research with an international team of collaborators.

	Predictive kinetic model paves the way for designing microbial factories The microbe E. coli gets a bad rap in the food industry, but in the chemical engineering field, it is one of the most important microorganisms for producing amino acids, bioethanol, vitamins and more. Researchers in Penn State's Chemical and Biological Systems Optimization Lab have developed a near genome-scale kinetic model of Escherichia coli's metabolic processes, which will allow scientists to quickly and efficiently use computer modeling to predict the effects that multiple gene interventions have on the microbial factories.
	Space cucumbers reveal secrets of plant survival Plants are experts in survival and can control the direction of their roots to maximize the use of resources around them. Using specialized cells, they can sense gravity and redistribute hormones, called auxins, to stimulate growth and allow vital features of the plant to develop. However, a big puzzle is how this transport process occurs at a cellular level. To learn more, researchers in Japan examined cucumber seedlings germinated under the very weak gravity—or microgravity—conditions of the International Space Station.
	Wild strawberry that inhibits the development of the spotted-wing Drosophila fly The so-called spotted-wing Drosophila (Drosophila suzukii) was first described from Japan in the 1930s. In 2008 it was recognized as an emerging global pest of soft-fruit crops. Among commercially important fruits, D. suzukii can drastically diminish yields of cherries, raspberries, peaches, plums, grapes and strawberries. Unlike other drosophilid species, the females of the species lay their eggs in fresh rather than fermenting fruits. When the larvae hatch, they consume the fruit pulp within a very short time. Now researchers led by LMU biologists Nicolas Gompel and Martin Parniske, in collaboration with the strawberry breeder Klaus Olbricht (Hansabred GmbH Co. KG, Dresden), have identified a wild strawberry in which the development of the larvae is suppressed, thus countering the spread of the pest. The new findings appear in the journal Frontiers in Plant Science.
