Submission + - Idaho Lab Produces World's First Molten Salt Fuel For Nuclear Reactors (cowboystatedaily.com)

Submitted by schwit1
schwit1 writes: The U.S. Department of Energy Office of Nuclear Energy announced this week that researchers at INL have successfully created the first batch of fuel salt.

Fuel salt is a molten salt mixture used as both a carrier for nuclear fuel and coolant in a molten salt reactor, a type of advanced nuclear reactor.

The fuel salt is critical for conducting the world’s first fast-spectrum, salt-fueled reactor test, known as the Molten Chloride Reactor Experiment (MCRE).

The test will help inform the future commercial deployment of a new class of advanced nuclear reactors, something a number of Wyoming-connected companies are proposing to build.

“There is a lot of push for this,” said James King, project lead for the Molten Chloride Experiment at INL. “We need to have a lot of different options so we can move away from less safe power generations methods.

“This is one of those technologies that can move us to better safety.”

The liquid form of the salt fuel means the fuel can’t melt. The technology would also offer another low-carbon alternative to generating power.

Submission + - USA will bar visa applicants who combat disinformation (npr.org) 1

Submitted by ClickOnThis
ClickOnThis writes: The Trump administration wants to bar visa applicants who combat disinformation and hate speech from entering the USA on work visas, on the grounds that they practice 'censorship.' From the article:

The directive, sent in an internal memo on Tuesday, is focused on applicants for H-1B visas for highly skilled workers, which are frequently used by tech companies, among other sectors. The memo was first reported by Reuters; NPR also obtained a copy.

"If you uncover evidence an applicant was responsible for, or complicit in, censorship or attempted censorship of protected expression in the United States, you should pursue a finding that the applicant is ineligible" for a visa, the memo says. It refers to a policy announced by Secretary of State Marco Rubio in May restricting visas from being issued to "foreign officials and persons who are complicit in censoring Americans."

Submission + - More Airbus A320 issues (cnn.com)

Submitted by schwit1
schwit1 writes: Airbus has identified an issue affecting “a limited number” of metal panels in its A320 passenger planes, a spokesperson for the company said Monday, just days after warning of another technical problem in its aircraft.

The plane manufacturer is inspecting all aircraft that are potentially impacted by what it called a “supplier quality issue,” but expects that only some of them will require further action be taken, the spokesperson told CNN.

“The source of the (metal panels) issue has been identified, contained and all newly produced panels conform to all requirements,” the spokesperson said, noting that the number of planes in service affected by the problem is “very limited.”

Submission + - Poor mental health linked to dark web use (phys.org) 1

Submitted by alternative_right
alternative_right writes: A new Florida Atlantic University study reveals significant mental health differences between dark web users and those who use only the surface web, and sheds light on a group whose involvement in this secretive online space has largely kept them outside the scope of traditional research.

Published in the journal Cyberpsychology, Behavior, and Social Networking, the study finds that dark web users reported substantially higher levels of depressive symptoms and paranoid thoughts as compared to surface web users. In addition, there were substantial differences between dark web users and surface web users pertaining to suicidal thoughts, non-suicidal self-injury and digital self-harm.

Adults who reported suicidal thoughts had nearly three times greater odds of reporting dark web use. Likewise, those who reported non-suicidal self-injury (e.g. cutting or burning oneself) were nearly five times more likely to report use of the dark web, and individuals who had engaged in digital self-harm (anonymously posting hurtful or negative comments about themselves online) had more than 19 times greater odds of reported dark web use.

"Our findings suggest that many individuals who turn to the dark web may be doing so not just for privacy concerns, but as a reflection of deeper mental health struggles and the possible desire to socialize and engage in information-seeking in a context free of scrutiny that might otherwise be experienced on the surface web or offline," said Meldrum.

Submission + - Why meetings can harm employee well-being (phys.org) 1

Submitted by alternative_right
alternative_right writes: On average, managers spend 23 hours a week in meetings. Much of what happens in them is considered to be of low value, or even entirely counterproductive. The paradox is that bad meetings generate even more meetings in an attempt to repair the damage caused by previous ones.

A 2015 handbook laid the groundwork for the nascent field of "Meeting Science". Among other things, the research revealed that the real issue may not be the number of meetings, but rather how they are designed, the lack of clarity about their purpose, and the inequalities they (often unconsciously) reinforce.

Faced with what we call meeting madness, the solution is not to eliminate meetings altogether, but to design them better. It begins with a simple but often forgotten question: why are we meeting?
