  DARPA: Five Teams of Researchers Will Help DARPA Detect Undersea Activity by Analyzing Behaviors of Marine Organisms

  Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA's Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters. This new, bio-centric PALS technology will augment the Department of Defense's existing, hardware-based maritime monitoring systems and greatly extend the range, sensitivity, and lifetime of the military's undersea surveillance capabilities. DARPA first announced the PALS program in February 2018 with the goal of incorporating biology into new solutions for monitoring adversary movements across the seemingly endless spaces of the world's oceans and seas. Ubiquitous, self-replicating, self-sustaining sea life is adaptable and highly responsive to its environment, whereas maritime hardware is resource intensive, costly to deploy, and relatively limited in its sensing modalities. According to PALS program manager Lori Adornato, “Tapping into the exquisite sensing capabilities of marine organisms could yield a discreet, persistent, and highly scalable solution to maintaining awareness in the challenging underwater environment.” The DARPA-funded PALS teams must develop or apply technologies to record stimulus responses from observed organisms, and develop combined hardware and software systems that interpret those responses, screen out false positives, and transmit analyzed results to remote end users. The teams' solutions will incorporate technologies such as hydrophones, sonar, cameras, and magnetic, acoustic, and kinetic sensors. The team led by Northrop Grumman Corporation, under principal investigator Robert Siegel, will record and analyze acoustics from snapping shrimp and optical activity by bioluminescent organisms. The team led by the Naval Research Laboratory, under principal investigator Lenny Tender, will integrate microbial organisms into a sensing platform to detect and characterize biological signals from natural microorganisms that respond to the magnetic signatures of underwater vehicles. The team led by Florida Atlantic University, under principal investigator Laurent Cherubin, will record and analyze vocalization cues from goliath grouper in tropical and subtropical environments. The team led by Raytheon BBN Technologies, under principal investigator Alison Laferriere, will use snapping shrimp as sources of opportunity for long-range detection, classification, and tracking of underwater vehicles. The team led by the University of Maryland Center for Environmental Science, under principal investigator David Secor, will tag black sea bass with sensors to track the depth and acceleration behaviors of schools of fish that are perturbed by underwater vehicles. DARPA is also funding the Naval Undersea Warfare Center, Division Newport, under principal investigator Lauren Freeman, to develop a seafloor system that uses a hydrophone array and acoustic vector sensor to continuously monitor ambient biological sound in a reef environment for anomalies. The system will analyze changes in the acoustic signals radiated by the natural predator-avoidance response of coral reef ecosystem biota, which could offer an indirect mechanism to detect and classify underwater vehicles in near-real time. DARPA conceived of PALS as a four-year research program with the expectation that researchers will be able to publish results for review by the broader scientific community. However, if DARPA identifies any of the data, results, or technical specifications as controlled unclassified information, DARPA will require the PALS researchers to protect them to prevent proliferation outside of official channels. https://www.darpa.mil/news-events/2019-02-15

  Secretive, never profitable Palantir makes its market debut

  Frank Bajak, The Associated Press BOSTON — Seventeen years after it was born with the help of CIA seed money, the data-mining outfit Palantir Technologies is finally going public in the biggest Wall Street tech offering since last year's debut of Slack and Uber. Never profitable and dogged by ethical objections for assisting in the Trump administration's deportation crackdown, Palantir has forged ahead with a direct listing of its stock, which is set to begin trading Wednesday. In its stock offering, the company isn't selling newly minted shares to raise money; it's simply listing existing shares for public trading. The low-key strategy may not generate the enthusiasm many technology offerings do. But it's in character for a secretive company long reliant on spies, cops and the military as customers — and whose founders are holding onto voting control of the company. The big question for both investors and company management: Can Palantir successfully transition from a business built on the costly handholding of government customers to serving corporate customers at scale? The company is a hybrid provider of software and consulting services that often embeds its own engineers with clients. Analysts say its future depends on selling multinationals on its tools for gathering disparate data from an ever-expanding data universe and using artificial-intelligence technology to find previously undetectable patterns. Those can theoretically guide strategic decisions and identify new markets much as they have aided in tracking terrorists and sorting military intelligence. The company sets itself apart from most U.S. technology providers, and just moved its headquarters to Denver from Silicon Valley. Palantir colors itself patriotic and belittles other tech firms that won't unquestionably support U.S. dominance in war fighting and intelligence. “Our software is used to target terrorists and to keep soldiers safe,” CEO Alex Karp wrote in a letter accompanying Palantir's offering prospectus. While Karp acknowledged the ethical challenge of building software that “enables more effective surveillance by the state,” Palantir's prospectus touts its work helping U.S. soldiers counter roadside bombings and fight the Islamic State group. The iconoclastic entrepreneur and PayPal co-founder endorsed President Donald Trump in 2016, worked on his transition team and holds the largest chunk of Palantir stock. Thiel already exerts tremendous power from the board of Facebook, which dominates global media and seeks to create a digital currency. In its IPO prospectus, Palantir paints a dark picture of faltering government agencies and institutions in danger of collapse and ripe for rescue by a “central operating system” forged under Thiel's auspices. As the offering is structured, Thiel will be the dominant voice among the Palantir co-founders who will retain voting control. “Is that someone who you want deciding how a component of the (national) security apparatus is designed?” asked New York University business professor Scott Galloway. “If you believe that power corrupts and checks and balances are a good idea, this is just from the get-go a really bad idea.” Earlier in September, BuzzFeed reported that Thiel hosted a known white nationalist, Kevin DeAnna, at a 2016 dinner party, citing emails it obtained and published whose authors refused to talk to the online news outlet. Thiel declined through a spokesman to discuss the report with The Associated Press. Critics say he shares the blame for Facebook's incomplete removal of toxic disinformation disseminated by the pro-Trump far-right fringe. Then there are Palantir's fundamentals, which Galloway considers lousy. The company has just 125 customers in 150 countries, including Airbus, Merck, Credit Suisse and the Danish National Police. Slightly less than half its 2019 revenues were from government agencies, and three clients — which Palantir did not name — accounted for almost a third of revenues. “They're massively unprofitable and they've never been able to figure it out,” Galloway said, noting that it took Google three years to earn a profit, and Amazon seven. Over a much longer span, Palantir has accumulated $3.8 billion in losses, raised about $3 billion and listed $200 million in outstanding debt as of July 31. Palantir, named for the mystical all-seeing stones from Tolkien's “Lord of The Rings,” has recently been deepening its relationship with Uncle Sam, including winning a modest contract early in the COVID-19 pandemic for helping the White House gather data on the virus' impact. Senior emerging technology analyst Brendan Burke of Pitchbook says he isn't worried that Thiel's association with Trump will hurt the company if Trump loses the election. “The political connections don't appear to be the main driver of their recent substantial contract wins,” he said, although he noted that government contracts can be more volatile than corporate ones, where Palantir's foothold is less firm. Palantir offers two software platforms. Foundry is designed to link disparate and largely incompatible data sources into a central operating system. It's the company's primary hope for broadening its business. An earlier product, Gotham, has been used by defense and intelligence analysts and police departments to identify patterns deep within datasets. But the value of “predictive policing” tools developed with the platform have been questioned for their potential to unfairly target people of color. The New Orleans and New York City police departments, once customers, have used it. A 2017 research paper by University of Texas sociologist Sarah Brayne, who studied the Los Angeles Police Department's use of Gotham, found the software could lead to a proliferation of unregulated personal data collected by police from commercial and law enforcement databases. On Monday, Amnesty International issued a briefing that says Palantir is failing to conduct human rights due diligence around its contracts with Immigration and Customs Enforcement, calling it “deeply ironic” that the company crows about its determination not to work with regimes like China that abuse human rights. Palantir's ICE contracts involve the maintenance and improvement of two products used in deportation raids. One of them, its web-based Falcon tool, has enhanced data accessible to investigators “involving the illegal movement of people into, within, and out of the United States,” according to documents obtained by The Associated Press, including court records, and by the nonprofit Electronic Privacy Information Center in a freedom-of-information request. Palantir has acknowledged in its SEC filing that “unfavorable coverage in the media” and from social activists could hurt its business. It also says its contractual obligations might prevent it from being able to defend its actions publicly, although it recently named a former Wall Street Journal reporter to its board. Negative publicity over ICE contracts may also have hurt company recruitment on college campuses. https://www.defensenews.com/industry/2020/09/30/secretive-never-profitable-palantir-makes-its-market-debut/
