During the past several years, in my capacity as deputy director and then acting director of national intelligence, I have participated in National Security Council meetings about immediate challenges, from North Korea's aggressive missile and nuclear development programs to Russian military operations along its borders, and from ISIS threats to the homeland to Chinese activity in the South China Sea. Michael Dempsey is the national intelligence fellow at the Council on Foreign Relations and the former acting director of national intelligence. The author is an employee of the US government on a sponsored fellowship, but all opinions are those of the author and do not reflect the official views of the US government. Even in instances in which the threat the US confronted was especially complex, there was at least a familiar policy playbook of options, as well as a shared understanding of how to approach these crises. However, in today's dynamic security landscape, it's fair to ask whether US policymakers might soon be forced to grapple with a new series of threats for which we have no common understanding or carefully considered counter-measures.

If Uber's scandals, lawsuits, and federal investigations haven't already driven you into the backseat of its competition just yet, maybe this will: Lyft is launching a fleet of self-driving cars and select customers in the San Francisco Bay Area will be offered free rides in autonomous cars developed and operated by self-driving outfit Drive.ai. "We really want to understand, what are all the pieces that need to come into place?" For Drive.ai, a two-year-old self-driving startup, it's a chance to see test out its tech and see how real customers interact with its product. To start, the program will include about a dozen AVs (drawn from Drive.ai's mixed fleet of Lincoln MKZ and Audi A4 sedans), but that number will grow as the company starts spending the $50 million it recently raised in a Series B funding round led by VC firm New Enterprise Associates. Both companies will collect data from customers (mostly through in-app reviews) about their experience, in the hopes of making sure they're comfortable, or at least not terrified. Uber started a pilot program in Pittsburgh last year, which it has since expanded to Tempe, Arizona.

The iPhone has been my primary smartphone for well over a decade, and therefore I've had Siri on my phone ever since its introduction in 2011. But I never really found a reason to use it. I've always felt self-conscious when talking to my phone -- I find people who use voice commands in public really annoying -- so I wanted to avoid doing it myself. I have Bluetooth in my car so I don't have to use my phone while driving, and when I'm at home, I have my trusty fingers instead. So I imagined that being forced to use Siri for a whole week was going to be a nightmare.

SpaceX is poised to fire off a fresh Falcon 9 rocket on Thursday, delivering a comically tiny payload for Taiwan's National Space Organization. At 1,047 pounds, the Formosat-5 Earth-observing satellite is almost light enough for a human to deadlift--but it'll launch atop a Falcon 9 rocket with 50 times more capacity. The overkill is thanks to a years-long delay, and SpaceX will take a substantial financial hit to make good on a contract it signed in 2010. Elon Musk's spaceflight company will attempt to launch the rocket from Vandenberg Air Force base in California during a 42-minute window opening at 11:51am PDT on Thursday. The satellite is bound for heliosynchronous orbit, where it will pass over Taiwan every two days for data retrieval. After the lightest single payload to ever hitch a ride on a Falcon 9 separates, the booster will fly back for a drone ship landing--hopefully to be reused in future, more economically viable missions.

Austin Russell hops in a motorized cart and goes whizzing through a cavernous building on the edge of San Francisco Bay that is normally used to disembark cruise-ship passengers. As the lanky 22-year-old CEO tools around, he passes a mannequin, a tire and a co-worker on a bicycle--all elements of a demonstration to show how well his company's sensor can monitor the environment. On a nearby screen, those shapes appear in rainbow colors that signify exactly how far away they are. All of it is the result of laser beams shooting out of a black box and bouncing off more than a million points around the room every second. "It's easy to make an autonomous vehicle that works 99% of the time," Russell says later.

Francis Harry Compton Crick OM FRS[1][4] (8 June 1916 – 28 July 2004) was a British molecular biologist, biophysicist, and neuroscientist, most noted for being a co-discoverer of the structure of the DNA molecule in 1953 with James Watson, work which was based partly on fundamental studies done by Rosalind Franklin, Raymond Gosling and Maurice Wilkins. Together with Watson and Maurice Wilkins, he was jointly awarded the 1962 Nobel Prize in Physiology or Medicine "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material".[3][6] Crick was an important theoretical molecular biologist and played a crucial role in research related to revealing the helical structure of DNA. He is widely known for use of the term "central dogma" to summarize the idea that genetic information flow in cells is essentially one-way, from DNA to RNA to protein.[7] During the remainder of his career, he held the post of J.W. Kieckhefer Distinguished Research Professor at the Salk Institute for Biological Studies in La Jolla, California. His later research centered on theoretical neurobiology and attempts to advance the scientific study of human consciousness. He remained in this post until his death; "he was editing a manuscript on his death bed, a scientist until the bitter end" according to Christof Koch.[8] Crick was the first son of Harry Crick (1887–1948) and Annie Elizabeth Crick (née Wilkins; 1879–1955). He was born and raised in Weston Favell, then a small village near the English town of Northampton, in which Crick's father and uncle ran the family's boot and shoe factory. His grandfather, Walter Drawbridge Crick (1857–1903), an amateur naturalist, wrote a survey of local foraminifera (single-celled protists with shells), corresponded with Charles Darwin,[9] and had two gastropods (snails or slugs) named after him. At an early age, Francis was attracted to science and what he could learn about it from books. As a child, he was taken to church by his parents. But by about age 12, he said he did not want to go anymore, as he preferred a scientific search for answers over religious belief.[10] Walter Crick, his uncle, lived in a small house on the south side of Abington Avenue; he had a shed at the bottom of his little garden where he taught Crick to blow glass, do chemical experiments and to make photographic prints. When he was eight or nine he transferred to the most junior form of the Northampton Grammar School, on the Billing Road.

Tropical cyclone wind-intensity prediction is a challenging task considering drastic changes climate patterns over the last few decades. In order to develop robust prediction models, one needs to consider different characteristics of cyclones in terms of spatial and temporal characteristics. Transfer learning incorporates knowledge from a related source dataset to compliment a target datasets especially in cases where there is lack or data. Stacking is a form of ensemble learning focused for improving generalization that has been recently used for transfer learning problems which is referred to as transfer stacking. In this paper, we employ transfer stacking as a means of studying the effects of cyclones whereby we evaluate if cyclones in different geographic locations can be helpful for improving generalization performance. Moreover, we use conventional neural networks for evaluating the effects of duration on cyclones in prediction performance. Therefore, we develop an effective strategy that evaluates the relationships between different types of cyclones through transfer learning and conventional learning methods via neural networks.

Among the tasks you can train a computer to perform is scanning the skies over the U.S. for the alarming number of surveillance and spy aircraft. The news web site BuzzFeed did just that, reporting this week that it employed a machine-learning algorithm to first recognize known spy planes, and then combine that model with a large set of flight-tracking data from a commercial web site. The AI project mapped thousands of surveillance flights operated by federal agencies over a four-month period, including a military contractor tracking terrorists in Africa that is also flying surveillance aircraft over U.S. cities, BuzzFeed reported. Flightradar24 gathers data from a network of ground-based receivers supplemented by Federal Aviation Administration receivers. The ground radars sweep up a flight data transmitted by aircraft transponders, including unique identifiers for each plane. The aerial gumshoes then used an algorithm called Random Forest (referred to on Github as randomForest, Random Forests, random-forest and variations of those names).

Defense Secretary James Mattis has a lot on his mind these days. Mattis admitted to that concern Thursday during the Silicon Valley leg of a West Coast tour that includes visits to Amazon and Google. When WIRED asked Mattis if the US had ambitions to harness recent progress in AI for military purposes like those recently espoused by China, he said his department needed to do more with the technology. "It's got to be better integrated by the Department of Defense, because I see many of the greatest advances out here on the West Coast in private industry," Mattis said. Mattis, speaking in Mountain View, a stone's throw from Google's campus, hopes the tech industry will help the Pentagon catch up.
