The human brain was initially used for basic survival tasks, such as staying safe and hunting and gathering. Yet, 200,000 years later, the same human brain is able to learn abstract concepts, like momentum, energy and gravity, which have only been formally defined in the last few centuries.

New research from Carnegie Mellon University has now uncovered how the brain is able to acquire brand new types of ideas. Published in Psychological Science, scientists Robert Mason and Marcel Just used neural-decoding techniques developed at CMU to identify specific physics concepts that advanced students recalled when prompted. The brain activation patterns while thinking about the physics concepts indicated that all of the students’ brains used the ancient brain systems the same way, and the patterns revealed how the new knowledge was formed — by repurposing existing neural systems.

The findings could be used to improve science instruction.

Another pre-Quantum Computing interim solution for super computing. So, we have this as well as Nvidia’s GPU. Wonder who else?

In summer 2015, US president Barack Obama signed an order intended to provide the country with an exascale supercomputer by 2025. The machine would be 30 times more powerful than today’s leading system: China’s Tianhe-2. Based on extrapolations of existing electronic technology, such a machine would draw close to 0.5GW – the entire output of a typical nuclear plant. It brings into question the sustainability of continuing down the same path for gains in computing.

One way to reduce the energy cost would be to move to optical interconnect. In his keynote at OFC in March 2016, Professor Yasuhiko Arakawa of University of Tokyo said high performance computing (HPC) will need optical chip to chip communication to provide the data bandwidth for future supercomputers. But digital processing itself presents a problem as designers try to deal with issues such as dark silicon – the need to disable large portions of a multibillion transistor processor at any one time to prevent it from overheating. Photonics may have an answer there as well.

Three months after a Department of Homeland Security intelligence report downplayed the threat of a cyber attack against the U.S. electrical grid, DHS and the FBI began a nationwide program warning of the dangers faced by U.S. utilities from damaging cyber attacks like the recent hacking against Ukraine’s power grid.

The nationwide campaign by DHS and the FBI began March 31 and includes 12 briefings and online webinars for electrical power infrastructure companies and others involved in security, with sessions in eight U.S. cities, including a session next week in Washington.

The unclassified briefings are titled “Ukraine Cyber Attack: Implications for U.S. Stakeholders,” and are based on work with the Ukrainian government in the aftermath of the Dec. 23 cyber attack against the Ukrainian power infrastructure.

When Khoshnevis imagines the future of colonies on Mars, he imagines very tall buildings, with a lot of protection from the elements.

“Gravity is one third of Earth’s, and therefore with less construction material we can build stronger structures out there, therefore we can build much taller,” he says. “The cost of energy for elevators and all that will be much less. Theoretically everything could be three times as high as here with the same consumption of energy,” he says.

“Virtually all new fossil fuel-burning power-generation capacity will end up “stranded”. This is the argument of a paper by academics at Oxford university. We have grown used to the idea that it will be impossible to burn a large portion of estimated reserves of fossil fuels if the likely rise in global mean temperatures is to be kept below 2C. But fuels are not the only assets that might be stranded. A similar logic can be applied to parts of the capital stock.”

In 2012, the US Navy initiated the SSL Technology Maturation (SSL-TM) program, in which industry teams led by BAE Systems, Northrop Grumman, and Raytheon, among others, competed to develop a shipboard laser with a beam power of 100 kW to 150 kW by 2016.

Boosting beam power further—to something like 200 kW or 300 kW—could permit a laser to counter at least some ASCMs. Even stronger beam powers—on the order of at least several hundred kW, if not one megawatt (MW) or more—could improve a laser’s effectiveness against ASCMs (Anti-Ship Cruise Missile) and enable it to counter ASBMs (Anti-Ship Ballistic Missile.

By 2020, it should be possible to demonstrate a 250–500 kW laser weapon system, one appropriate for deployment on current surface combatants and capable of being a game changer in the Navy’s struggle to address the growing A2/AD challenge.

A team of scientists from Texas A&M AgriLife Research wants to replicate an alga’s ability to produce big amounts of oil for biofuel.

Industrial Technology Research Institute (ITRI) is located at Central Taiwan Innovation and Research Park in Nantou, Taiwan. It is expected to become the central facility of the Science Park to be built in this region. Noiz Architects and Bio Architecture Formosana won the competition to design the building in 2010. During the development phase, the project site had to be relocated once during the design development phase, and the construction finally completed in September 2014.

BURLINGTON, MA—(Marketwired — Apr 5, 2016)

DNV GL, the world’s largest resource of independent energy experts and certification, together with its partners, Group NIRE and Geli (Growing Energy Labs, Inc.), will produce and operate an Internet of Energy (IoEn) platform integrating the management of up to 100 distributed energy resources (DER).

The award, DNV GL’s third from ARPA-E, is one of twelve new projects in the Department of Energy’s Network Optimized Distributed Energy Systems (NODES) program announced in December.
