A cohesive-frictional force field (CFFF) for colloidal calcium-silicate-hydrates

Calcium-silicate-hydrate (C-S-H) gel is a cohesive-frictional material that exhibits strength asymmetry in compression and tension and normal-stress dependency of the maximum shear strength. Experiments suggest the basic structural component of C-S-H is a colloidal particle with an internal layered structure.

High-throughput droplet microfluidics screening platform for selecting fast-growing and high lipid-producing microalgae from a mutant library

Biofuels derived from microalgal lipids have demonstrated a promising potential as future renewable bioenergy. ... In this work, we present a high-throughput droplet microfluidics-based screening platform capable of analyzing growth and lipid content in populations derived from single cells of a randomly mutated microalgal library to identify and sort variants that exhibit the desired traits such as higher growth rate and increased lipid content.

ORNL budget has more at stake this year as GOP sets priorities

President Donald Trump's budget proposal slashing funds for scientific research was declared "dead on arrival" when it reached Congress. But as the 2018 fiscal year begins Sunday, questions remain about important programs at Oak Ridge National Laboratory now that Republicans control the national government.

Expected WIPP roof collapse raises anxiety

In the coming weeks, deep inside the Waste Isolation Pilot Plant in Carlsbad, large blocks of salt rock are expected to collapse inside a room containing six irradiated vehicles, each holding gasoline. The room is packed with radioactive waste, and the entrance has been sealed to prevent workers from entering.

ORNL Innovation Crossroads program opens second round of energy entrepreneurial fellowships

Oak Ridge National Laboratory encourages entrepreneurs to apply for the second round of Oak Ridge National Laboratory's Innovation Crossroads program. ... Innovation Crossroads is one of three U.S. Department of Energy Lab-Embedded Entrepreneurship Programs designed to embed top technical post-doctoral talent within national labs as research fellows with goal of subsequently launching businesses.

Nuclear regulators debate new challenges

International cooperation is high in the nuclear industry, but harmonising regulatory processes remains a challenge, delegates heard at the World Nuclear Association's annual symposium held in London recently. In addition, regulatory bodies face new tasks - licensing advanced reactor technologies, enhancing public confidence and assisting newcomer countries.

Secretary Perry Urges FERC to Take Swift Action to Address Threats to Grid Resiliency

WASHINGTON, D.C. - Today, U.S. Secretary of Energy Rick Perry formally proposed that the Federal Energy Regulatory Commission (FERC) take swift action to address threats to U.S. electrical grid resiliency. Pursuant to his authority under Section 403 of the Department of Energy Organization Act, the Secretary urged the Commission to issue a final rule requiring its organized markets to develop and implement reforms that would fully price generation resources necessary to maintain the reliability and resiliency of our nation's grid.

First open-access data from large collider confirm subatomic particle patterns

CERN Open Data Portal results reveal predictable patterns from colliding high-energy protons. ... In a paper published [September 26] in Physical Review Letters, the researchers used the CMS data to reveal, for the first time, a universal feature within jets of subatomic particles, which are produced when high-energy protons collide. Their effort represents the first independent, published analysis of the CMS open data. (https://doi.org/10.1103/PhysRevLett.119.132003)

Ultra-fast and ultra-sensitive hydrogen sensor

A KAIST team made an ultra-fast hydrogen sensor that can detect hydrogen gas levels under 1 percent in less than seven seconds. The sensor also can detect hundreds of parts per million levels of hydrogen gas within 60 seconds at room temperature. (https://dx.doi.org/10.1021/acsami.7b10908)

A Potential New and Easy Way to Make Attosecond Laser Pulses: Focus a Laser on Ordinary Glass

This novel method could shrink the equipment needed to make laser pulses that are billionths of a billionth of a second long for studying ultra-speedy electron movements in solids, chemical reactions and future electronics. (https://dx.doi.org/10.1038/s41467-017-00989-4)

UMD partners with Fraunhofer, Signature Science on DNA screening technologies

Computational biologists in the University of Maryland Institute for Advanced Computer Studies (UMIACS) are collaborating with other experts to develop new approaches and tools for screening DNA sequences that might accidently-or intentionally-be altered, resulting in a biological threat.

Critical Code in Millions of Macs Isn't Getting Apple's Updates

As any nagging cybersecurity expert will tell you, keeping your software up to date is the brushing and flossing of digital security. But even the most meticulous practitioners of digital hygiene generally focus on maintaining the updates of their computer's operating system and applications, not its firmware. ... Now one new study has found that the most critical elements of millions of Macs' firmware aren't getting updates.

IAEA says North Korea's rapid weapons progress poses new, global threat

SEOUL - The United Nations nuclear watchdog's chief said on Friday North Korea's sixth nuclear test conducted on Sept. 3 showed the isolated country has made rapid progress on weapons development that posed a new, global threat.

Senate passes small business cybersecurity legislation

Work and the Loneliness Epidemic

In the workplace, many employees - and half of CEOs - report feeling lonely in their roles. ... Researchers for Gallup found that having strong social connections at work makes employees more likely to be engaged with their jobs and produce higher-quality work, and less likely to fall sick or be injured.

Employees with Work-Related Asthma at High Risk of Pneumococcal Pneumonia

Adults with asthma are at increased risk for pneumococcal disease, yet according to a new study published in the American Journal of Preventive Medicine, just 54 percent of adults with work-related asthma - asthma triggered by an exposure at work - have been vaccinated against the infection.
