Enhanced bending failure strain in biological glass fibers due to internal lamellar architecture

The remarkable mechanical properties of biological structures, like tooth and bone, are often a consequence of their architecture. The tree ring-like layers that comprise the skeletal elements of the marine sponge Euplectella aspergillum are a quintessential example of the intricate architectures prevalent in biological structures.

Cu2O/TiO2 heterostructures for CO2 reduction through a direct Z-scheme: Protecting Cu2O from photocorrosion

The development of artificial photosynthesis aims to solve the increasing energy demand and associated environmental problems. A model photosynthetic system employing a composite of semiconductors with a Z-scheme can potentially mimic the combined power of photosystems 1 and 2 to transfer electrons. In this work, octahedral cuprous oxide covered with titanium dioxide nanoparticles (Cu2O/TiO2) are synthesized by a solvothermal strategy that provides high morphological and crystallographic control.

Energy secretary questions if Hanford money is well spent

Questions need to be answered about whether money is being well spent at the Hanford nuclear reservation, said Energy Secretary Rick Perry at a Senate subcommittee hearing on Wednesday. Both Sen. Patty Murray, D-Wash., and Sen. Jeff Merkley, D-Ore., questioned Perry about spending cuts for environmental cleanup at Hanford included in a fiscal 2018 budget proposal from President Trump's administration.

Beyond Uncertainties, Sandia Sees Growth in Weapons Program

The new director at Sandia's Livermore site anticipates growth in its nuclear weapons program, while dealing with substantial uncertainties in other areas, like the intentions of the Trump Administration, the slow speed of clearance investigations and the high cost of living in the Bay Area.

LANL defends plutonium production in wake of report

Los Alamos National Laboratory is fighting back this week in the wake of a critical report on safety issues at its plutonium production facility. The report by Patrick Malone and Jared Bennett of the Center of Public Integrity was published beginning Sunday and describes a safety review shutdown in 2013 that has slowed work on the manufacture and testing of new and existing plutonium pits at LANL.

Grant-winning Portland State researcher looks to overcome skepticism - his own - on ocean energy

If Jonathan Bird succeeds, one of the most significant obstacles to marine energy development could be overcome - along with his own doubts about the viability of generating energy from waves and tides. The U.S. Department of Energy thinks Bird's work on cutting-edge gearing systems has possibilities.

Canadian siting studies for commercial IMSR

Terrestrial Energy has begun a feasibility study for the siting of the first commercial Integral Molten Salt Reactor (IMSR) at Canadian Nuclear Laboratories' (CNL) Chalk River site, with a further vision of creating a technology hub at CNL to support the commercialisation of small modular reactors (SMR).

Multifunctional catalyst for poison-resistant hydrogen fuel cells

Japanese collaboration develops catalyst that can oxidize both hydrogen and carbon monoxide to produce energy. (http://dx.doi.org/10.1002/anie.201704864)

Study demonstrates a better way to store renewable energy

In an effort to find better ways to store renewable energy, physicists at the University of Arkansas, in collaboration with a scientist at the Luxembourg Institute of Science and Technology, have shown that antiferroelectrics can provide high energy density. The findings may lead to storage devices that improve the efficiency of wind and solar power. (http://dx.doi.org/10.1038/ncomms15682)

Tiny nanoparticles offer significant potential in detecting/treating disease new review of work on exosomes

Exosomes - tiny biological nanoparticles which transfer information between cells - offer significant potential in detecting and treating disease, the most comprehensive overview so far of research in the field has concluded. (https://doi.org/10.1016/j.molmed.2017.05.003)

In the General AI Challenge, Teams Compete for 5 Million [Dollars]

[Marek] Rosa [Founder of the General AI Challenge] recently took steps to scale up the research on general AI by founding the AI Roadmap Institute and launching the General AI Challenge. The AI Roadmap Institute is an independent entity that promotes big-picture thinking by studying and comparing R&D roadmaps towards general intelligence.

Insider threats often go undetected in high-security organizations, Stanford scholar finds

Stanford political scientist Scott Sagan says the evidence shows that while insider threats may be low-probability events on a day-to-day basis, over time they have a high probability of occurring. For companies, an insider threat from an employee can be an economic disaster. For a government unit, an insider threat can quickly become a dangerous national security issue.

'Stack Clash' Smashed Security Fix in Linux

What's old is new again: an exploit protection mechanism for a known flaw in the Linux kernel has fallen to a new attack targeting an old problem. The so-called Stack Clash vulnerability, which was discovered and disclosed by Qualys, affects Linux, OpenBSD, NetBSD, FreeBSD, and Solaris, on i386 and amd64 processors.

Trump holds meeting to address power grid cyber threats

President Trump met with energy sector leaders and cybersecurity experts on Wednesday to focus on combating threats to the U.S. power grid. The meeting occurred about a week after security researchers identified the malware tied to a cyberattack on Ukraine's power grid last year that, with slight modifications, could be used to disrupt the U.S. electric grid.

U.N. names Russian diplomat to new counterterrorism post

Can sitting cancel out the benefits of exercise?

You've probably heard the trendy phrase that "sitting is the new smoking." Although it's an exaggeration to equate the two behaviors - nothing comes close to smoking in its many ruinous and deadly effects on the body - research does show that prolonged sitting may be harmful, even if you exercise regularly.

Safety 2017: Seven safety leadership tips for supervisors

Small modular reactor funding uncertain

Certification of NuScale Power's small modular reactor design continues, even as a major source of its funding is in jeopardy. ... Congress ultimately will decide the budget, but DOE funds have been critical to development of the reactor ... Corvallis, Ore.-based NuScale plans to build the first-of-a-kind power plant at the DOE's desert site west of Idaho Falls.
