Breakthrough in next generation of storage batteries could transform the US electrical grid within five to 10 years, says research agency, Arpa-E.

Dear readers,
My son Ethan Kurzweil — who is a partner at Bessemer Ventures Partners — tracks the future of web innovation, social and legal concerns about privacy, and start-ups who have an edge with their business or consumer applications, like team sourcing or software-as-a-service.
He appeared on C • NBC business affairs show Power Lunch. Episode debated the recent news about the US government and law enforcement asking Apple to release private data on an iPhone used by terrorists.

In what appears at first to be a storyline ripped from a sci-fi thriller, a multi-national research team spread across two continents, four countries, and ten years in the making have created a model of a supercomputer that runs on the same substance that living things use as an energy source.
Humans and virtually all living things rely on Adenosine triphosphate ( ATP ) to provide the energy our cells need to perform daily functions. The biological computer created by the team led by Professor Dan Nicolau, Chair of the Department of Bioengineering at McGill, also relies on ATP for power.
The biological computer is able to process information very quickly and operates accurately using parallel networks like contemporary massive electronic super computers. In addition, the model is lot smaller in size, uses relatively less energy, and functions using proteins that are present in all living cells.

Fast radio bursts, or FRBs, are a source of endless fascination. But despite a decade of observations, not all astronomers are sure that they’re real. A study out in Nature today, which reports the very first recurring FRB, is now causing lingering skepticism to evaporate.
“I think this is pretty huge,” Peter Williams, an astronomer at Harvard’s Center for Astrophysics who was not involved with the study, told Gizmodo. “For awhile, I wasn’t sure these things were genuinely astrophysical. This paper settles the question.”
And Williams is not one to take splashy new claims about FRBs—high energy radio pulses of unknown origin, which flit across the sky for a fraction of a second—lightly. In fact, he’s spent the last week raising major doubts about another recent study, which, as Gizmodo and other outlets reported, claimed to have pinpointed the location of an FRB in space for the first time.

A new laser tag coming our way; however, this time when you’re tagged, you really are dead.
US officials tout the ‘unprecedented power’ of killing lasers to be released by 2023.
The US Army will deploy its first laser weapons by 2023, according to a recently released report.
Mary J. Miller, Deputy Assistant Secretary of the Army for Research and Technology, speaking before the House Armed Services Committee on Monday, stated that, “I believe we’re very close,” when asked about progress with directed-energy, or laser, weapons.

Australia’s coast, being both great surf territory as well as a primo shark habitat, is getting a technological upgrade to keep the swimmer-fish twain from meeting: A shark-spotting drone nicknamed the “Little Ripper.”
A joint venture between Aussie philanthropist Ken Weldon and Aussie bank Westpac, the $250,000 battery-powered unmanned helicopter will be deployed in the skies above New South Wales. On Sunday, New South Wales Premier Mike Baird heralded the drone as the future of oceanic search and rescue.
The Little Ripper will be able to monitor the shore for an hour before its battery kaputs, according to the Sydney Morning Herald. It’s part of a push for non-lethal, greener shark attack deterrents in Australia, where encounters are reportedly rising. They’re still fairly rare — as of November, there were 14 shark attacks off the Australian coast in 2015, reports The Guardian — but that’s a spike from the typical average of five or so. A separate $16 million shark detection initiative in New South Wales also includes buoys with advanced sonar that can, according to its creators, detect sharks 90 percent of the time.

Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, Cornell researchers hope their work with quantum dot solids — crystals made out of crystals — can help usher in a new era in electronics.
The team has fashioned two-dimensional superstructures out of single-crystal building blocks. Using a pair of chemical processes, the lead-selenium nanocrystals are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.

The difference between these and previous crystalline structures is the atomic coherence of each 5-nanometer crystal (a nanometer is one-billionth of a meter). They’re not connected by a substance between each crystal — they’re connected to each other directly. The electrical properties of these superstructures are potentially superior to existing semiconductor nanocrystals, with anticipated applications in energy absorption and light emission.
