Lucas123 writes: John Goodenough, the University of Texas researcher who this week demonstrated new battery cells that are safer and have at least three times as much energy density as today's standard Li-on batteries, responded to skeptics who said the technology described in research published in a peer-reviewed journal, appear to defy the laws of thermodynamics. In an article published Monday by Quartz , various energy experts took exception to Goodenough's claims, even calling them "unbelievable." Goodenough is also co-inventor of the original lithium-ion battery. In an email to Computerworld, Goodenough said "any new discovery invites strong skepticism." In this case, the skeptical scientists wondered how it is possible to strip lithium from the anode and plate it on a cathode current collector to obtain a battery voltage since the voltage is the difference in the chemical potentials (Fermi energies) between the two metallic electrodes,. "The answer is that if the lithium plated on the cathode current collector is thin enough for its reaction with the current collector to have its Fermi energy lowered to that of the current collector, the Fermi energy of the lithium anode is higher than that of the thin lithium plated on the cathode current collector," Goodenough said.

So I ask you, the Slashdot community, what are your personal experiences with any of the various VR systems out there? What are their strengths and weaknesses? What little things annoy you the most? What features make a given product the best (or worst) option?

He took full advantage of his post, using his gifted photographic eye to capture hundreds of images of everyday life in Moscow and across the U.S.S.R.
When he left the country in 1954 amid accusations of espionage, Major Manhoff took with him reels of 16 millimeter film and hundreds of color slides and negatives he shot during his travels – including of one of the Soviet Union's pivotal events, Josef Stalin's funeral.
But after his return to the United States, the trove of rare images lay forgotten, stored in cardboard boxes in a former auto body shop in the Pacific Northwest until its discovery by a Seattle-based historian.
AmiMoJo writes: Norway, which already boasts the world's highest number of electric cars per capita, said Monday that electric or hybrid cars represented half of new registrations in the country so far this year. Sales of electric cars accounted for 17.6 percent of new vehicle registrations in January and hybrid cars accounted for 33.8 percent, for a combined 51.4 percent, according to figures from the Road Traffic Information Council (OVF). In February, those proportions fell slightly but remained high at 15.8 percent and 32 percent, respectively. While cars with combustion engines are heavily taxed, electric vehicles are exempt from almost all taxes. Their owners also benefit from numerous advantages such as free access to toll roads, ferries and parking at public car parks, as well as the possibility of driving in bus lanes.

A bill brought by Sen. Ryan Osmundson, R-Buffalo, would eliminate that biannual ritual. He introduced Senate Bill 206 in the Senate State Administration Committee last month, a bill exempting Montana from observance of daylight saving time and keeping the state on “Montana Standard Time” throughout the year.
Similar legislation in several past sessions to exempt Montana from daylight saving time, keep the state on daylight saving time all year, or put the question to the voters failed to advance even out of committee. But SB206 passed committee unanimously and once on the floor, more than twice as many senators voted for it as against it.

Cryopreservation is the ability to preserve tissues at liquid nitrogen temperatures for long periods of time and bring them back without damage, and it's something scientists have been dreaming about achieving with large tissue samples and organs for decades.

JustAnotherOldGuy writes: A recent global study conducted by Kasperksy Lab reveals that social media users are interacting less face-to-face than in the past because of this newfound ability to constantly communicate and stay in touch online. In the study, researchers found that about one-third of people communicate less with their parents (31%), partners (23%), children (33%) and friends (35%) because they can simply follow them on social media. This may be doing more harm than good, in a world where editing one’s life to make it appear perfect is more appealing than naturally existing. Many participants made it clear that social media made them jealous of others. Nearly 60% of the participants viewed a friend as having a better life than their own simply by seeing that friend’s social media activity, and almost half were upset after viewing photos from a friend’s happy holiday celebration.
future guy writes: New Atlas reports, "A meta-analysis of worldwide studies conducted in 2005 definitively showed what many doctors had been anecdotally noting for decades. Schizophrenia patients were much more likely to become heavy smokers than than those in the general population. In fact some studies found over 80 percent of those diagnosed with schizophrenia were smokers. There were many social and psychological hypotheses proposed to explain this strange anomaly, but none were ever sufficient. A new study published in Nature Medicine has not only revealed how smoking can normalize the impairments in brain activity associated with schizophrenia, but unlocks an entirely new field of drug research to combat the disease."
PrintBetter writes: With just 3 days to go, backers are pulling out of Next Dynamics' NexD1 Kickstarter amidst fears the creator exaggerated progress on their prototype and tried to pass off prints purchased from Shapeways as their own.
Billed as the "first Multimaterial & Electronics 3D Printer" the Berlin company's campaign was a darling of Kickstarter, carrying their "Projects We Love" endorsement and receiving praise from publications like TechCrunch, 3DPrint.com and Make magazine for its purported ability to mix up to six plastic and conductive resins in a single print.
But as pledges grew to over half a million euros, backers started to sense things didn't add up. Kevin Holmes comments "Wow, I'm stunned — I cancelled my pledge already... Did they really buy parts from Shapeways and pass them off as their own?" while Anthony Webb remarks "I've backed over 100 projects on Kickstarter... but this one takes the cake for a complete scam."
Lucas123 writes: In 2016, the solar workforce in the U.S. increased by 25% to 374,000 employees, compared to 187,117 electrical generation jobs in the coal, gas and oil industries. Solar employment, which includes both photovoltaic electricity and concentrated solar steam generators, accounts for 43% of the electric power generation workforce — the largest share of workers in that sector. Fossil fuel generation employment now accounts for 22%. In addition to losing ground in employment, net power generation from coal sources declined by 53% between 2006 and September 2016; electricity generation from natural gas increased by 33%; and solar grew by over 5,000% —from 508,000 megawatt hours (MWh) to just over 28 million MWh.

Unless you're elderly or a baby, the common cold is by no means life-threatening. But it's very annoying and, worse still, you get no sympathy, just people backing away in case they catch it.
However, after decades of research, the fabled cure for the common cold could be on its way in the form of a nasal spray called SynGEM, which is the brainchild of a Dutch biotechnology company.
After successful tests on mice and rats (yes, they get colds too), 36 human volunteers at London's Imperial College are now trying out the spray, which is hoped to kill off a cold before you've even had time to buy that family pack of tissues.

Trailrunner7 writes: An industry led strike force is preparing to take away one of the most valuable pieces of technology used by phone scammers: caller ID spoofing.
The Robocall Strike Force, convened by the FCC and comprising wired and wireline telecom companies, has been working since August on a handful of new technologies, standards, and other techniques to help address the robocall problem. On Wednesday, members of the strike force delivered their report to the FCC and said that a trial of a new Do Not Originate list has shown tremendous promise in preventing scammers from being able to spoof numbers belonging to government agencies, charities, and other legitimate organizations.
A trial of the DNO list that’s been running for the last few weeks on some IRS numbers has resulted in a 90 percent drop in the volume of IRS scam calls, officials from AT&T, which leads the strike force, said during the FCC meeting Wednesday. The carriers on the strike force, which include Sprint, Verizon, and many others, plan to continue testing the DNO list in the coming months, with the intent to fully implement it some time next year.
