Apparently. Can you find out where he works?

Maybe at a "multinational technology company, specializing in internet-related services and products, with headquarters in the United States" or a "multinational corporation providing online social media and networking services?"

Submission + - Japanese Company Develops a Solar Cell With Record-Breaking 26%+ Efficiency (arstechnica.com)

An anonymous reader writes: The silicon-based cells that make up a solar panel have a theoretical efficiency limit of 29 percent, but so far that number has proven elusive. Practical efficiency rates in the low-20-percent range have been considered very good for commercial solar panels. But researchers with Japanese chemical manufacturer Kaneka Corporation have built a solar cell with a photo conversion rate of 26.3 percent, breaking the previous record of 25.6 percent. Although it’s just a 2.7 percent increase in efficiency, improvements in commercially viable solar cell technology are increasingly hard-won. Not only that, but the researchers noted in their paper that after they submitted their article to Nature Energy, they were able to further optimize their solar cell to achieve 26.6 percent efficiency. That result has been recognized by the National Renewable Energy Lab (NREL). In the Nature Energy paper, the researchers described building a 180.4 cm2 cell using high-quality thin-film heterojunction (HJ)—that is, layering silicon within the cell to minimize band gaps where electron states can’t exist. Controlling heterojunctions is a known technique among solar cell builders—Panasonic uses it and will likely incorporate it into cells built for Tesla at the Solar City plant in Buffalo, and Kaneka has its own proprietary heterojunction techniques. For this record-breaking solar cell, the Kaneka researchers also placed low-resistance electrodes toward the rear of the cell, which maximized the number of photons that collected inside the cell from the front. And, as is common on many solar cells, they coated the front of the cell with a layer of amorphous silicon and an anti-reflective layer to protect the cell’s components and collect photons more efficiently.

Submission + - John Goodenough responds to skeptics of his new lithium-on battery (computerworld.com)

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.

I recall years ago, there was speculation that non PDA-using man's newly-formed friendship with the canine species led to 'tracking prey via smell' as a task being offloaded to the dogs - leaving spare capacity for the brain to develop into PDA-using man.

As far as getting from A to B - the drivers are as involved as they need to be.

IBM, Remote-Work Pioneer, is Calling Thousands Of Employees Back To the Office (qz.com) 301

An anonymous reader shares a report: Less than a year into her tenure as IBM's chief marketing officer, Michelle Peluso prepared to make an announcement that she knew would excite some of her 5,500 new employees, but also, inevitably, inspire resignation notices from others. In a video message, Peluso explained the "only one recipe I know for success." Its ingredients included great people, the right tools, a mission, analysis of results, and one more thing: "really creative and inspiring locations." IBM had decided to "co-locate" the US marketing department, about 2,600 people, which meant that all teams would now work together, "shoulder to shoulder," from one of six different locations -- Atlanta, Raleigh, Austin, Boston, San Francisco, and New York. Employees who worked primarily from home would be required to commute, and employees who worked remotely or from an office that was not on the list (or an office that was on the list, but different than the one to which their teams had been assigned) would be required to either move or look for another job. Similar announcements had already been made in other departments, and more would be made in the future. At IBM, which has embraced remote work for decades, a relatively large proportion of employees work outside of central hubs. (By 2009, when remote work was still, for most, a novelty, 40% of IBM's 386,000 global employees already worked at home). [...] "When you're playing phone tag with someone is quite different than when you're sitting next to someone and can pop up behind them and ask them a question," Peluso says. Not all IBM employees see it that way.
