    You may remember Yvette Felarca, the middle school teacher who is also the leader of an Antifa Communist group in California. She made a bizarre appearance on Tucker Carlson’s show earlier this year. Felarca was arrested on Tuesday for battery and resisting arrest. There are photos online of Yvette Felarca being led away by police in handcuffs.

    A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage. Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge. The engineers describe...

    A disturbing Reddit thread claims that in 2008 the ex-business partner of James Alefantis, DC chef and restauranteur Carole Greenwood, caught Alefantis in the act of sexually battering her then 17 year-old son. Subsequent internet postings identified the location of the alleged crime scene as being Comet Ping Pong Pizza, a DC ping pong-themed pizzaria featuring live music acts. Citing a "family emergency", Greenwood abruptly terminated her business dealings with Alefantis and disappeared, finally surfacing as Executive Chef at Bethesda's Food & Wine Co. An anonymous poster to the thread, presumably Alefantis, objects to the dark story: "Why wouldn't I...

    A stuntman who worked on the USA Network series “Shooter” sued series star Tom Sizemore and Paramount Pictures Corp. Friday, claiming he was struck and seriously injured by an SUV driven by the allegedly drunken actor last summer. Steve DeCastro and his wife, Carly DeCastro, are the plaintiffs in the Los Angeles Superior Court lawsuit. They are seeking unspecified damages on allegations of negligence, unusual risk, battery, assault, intentional infliction of emotional distress and loss of consortium.

But whatever efficiency optimization Apple has baked into iOS 10, it seems they are not enough to make up for the measly 1,960mAh battery it decided to put in the case.

Yesterday we saw USC left tackle Chuma Edoga get himself ejected from a game against Utah State after getting a little bit too physical with a ref during the heat of the moment, but this video from the junior college ranks is even worse. Mt. San Antonio offensive lineman Bernard Schirmer took unsportsmanlike conduct to the next level when he allegedly punched a ref while being restrained, knocking the ref to the ground and later being taken away in handcuffs by local authorities. He was charged with suspicion of battery.

    The company says its new ‘Ludicrous’ P100D will be the ‘fastest car in the world’ Tesla Motors Inc. said it is offering its electric vehicles with a battery capable of going up to 315 miles on a charge, the first time a major auto maker has provided that much electric range in a vehicle. The company unveiled new versions of its Model S sedan and Model X sport-utility vehicle with 100 kilowatt-hour batteries; previously the largest battery size was 90 kwh. The upgrade—which Tesla executives said was made possible by increasing the energy density of its battery packs—will allow the...

    Well it seems the battery gods have heard our call and bestowed upon us a miracle.Researchers at the University of California Irvine (UCI) may have discovered a way to drastically increase the life of modern day batteries. And the best part is that they stumbled upon this solution by accident.To be more specific, the discovery was made by fifth-year PhD student, Mya Le Thai. Mya was working on an electrolyte gel that was to substitute the electrolyte liquid currently found in batteries in an attempt to make it more affordable. But in a coincidental twist of fate (thank you...

The flow can then be reversed by turning the device over.
