Science Six-Pack

By Carl Slaughter:  (1) Google’s super secret anti-aging research. “Google is super secretive about its anti-aging research. No one knows why.”.

We should pause for a moment to note how strange this is. One of the biggest and most profitable companies in the world has taken an interest in aging research, with about as much funding as NIH’s entire budget for aging research, yet it’s remarkably opaque.

Google also prides itself for being a leader on transparency and for its open culture. And we’re living in a time when the norms in science, particularly biomedical science, are centered around openness and data sharing. But these values have somehow eluded Calico.

For now, I think it’s safe to say Google has not solved aging. Or if it did, they haven’t told anybody.

(2) Inside DARPA. “Inside DARPA, The Pentagon Agency Whose Technology Has ‘Changed the World'”.

Welcome back to FRESH AIR. What are some of the most impressive successes of DARPA?

SHARON WEINBERGER: Well, let’s start with the first success that has really cemented DARPA’s reputation today. And that would be ARPANET, which was the precursor and laid the foundation for the modern Internet. That is undoubtedly the agency’s biggest success. And because of the name itself, ARPANET is sort of synonymous with DARPA today. But there are many other innovations that they get less credit for but in fact go back directly to the agency’s work. The driverless cars, autonomous self-driving cars that are now coming to fruition date back to a series of robotic car races that DARPA sponsored beginning in 2004, 2005.

Some of DARPA’s other biggest, quote, unquote, “successes” are stealth aircraft. They sponsored the development of the first stealth prototype aircraft in the 1970s. Precision weapons is another DARPA innovation. Drones, particularly the Predator drone that we now associate with the wars in Iraq, Afghanistan and elsewhere date back to DARPA sponsorship.

(3) Scientists versus politicians. “A Cold War theory for why scientists and the government have become so estranged”.

Indeed, a big reason why tens of thousands of scientists rallied in cities around the country last weekend was to counter what they see as “anti-science” attitudes taking hold in the United States — particularly in the US government. The March for Science, according to organizer Jonathan Berman, a biology postdoc at the University of Texas Health Science Center, sent “the message that we need to have decisions being made based on a thoughtful evaluation of evidence.”

But this raises the obvious question: Was the United States ever pro-science? Was there a golden age? And if so, why were things so different then? What’s changed?

(4) Space firms warn Congress. “US space firms tell Washington: China will take over the moon if you’re not careful”.

Robert Bigelow, a real-estate mogul who now operates an eponymous company dedicated to creating space habitats and building facilities on the moon, warned the Senate hearing that without a global legal framework, the US could be left behind.

“China is very pre-disposed to ownership, whether its creating the islands in South China Sea, properties in massive quantities that they’ve purchased in South America or Africa, whether you open a [foreign subsidiary in China] and can only own 49% of it,” he said. “China could exercise an effort to start to lay claim to certain lunar territories. I don’t think it’s a joke, I don’t think it’s something to be cavalier about. Such an ownership consequence would have an amazing impact on the image of China vis-a-vis the United States and the rest of the world, if they should own large amounts of territory on that body, if we stood back and we were not prepared.”

(5) Ted Cruz:  Unleash the commercial spaceships. “To infinity and beyond: Ted Cruz looks to encourage commercial space exploration”.

The Texas Republican convened a panel of top executives at private space exploration companies to solicit suggestions for reducing regulatory barriers to encourage further innovation.

By opening more commercial options for space exploration, Cruz said, they could be creating “the real possibility that in the not-too-distant future, American private citizens will be able to reach space from a launch pad or a runway in Texas.”

(6) Water covered planets. “Most Habitable Alien Planets May Be Totally Covered in Water”.

 Earth may be special because of its water, but not in the way you may think. A new study published in The Monthly Notices of the Royal Astronomical Society suggests that we may actually have less of it than average.

Astronomer Fergus Simpson of the University of Barcelona ran a series of computer simulations to determine what planets orbiting in their star’s habitable zones would look like. Habitable zone planets like Earth are the perfect distance from their host stars for liquid water to form on the surface and are prime candidates in the search for extraterrestrial life.

Simpson simulated what would happen to a wide range of habitable zone planets given a variety of starting conditions. The results were that planets tend to be either mostly water or mostly land, with very few in the middle. Most planets with any significant amount of water are likely to be dominated by it, and most planets in the habitable zone are almost completely waterworlds.

  1. Seems like the people in 4 have read the article in 3 and are trying to act on it.

  2. 1) My assumption is that someone high-up at Google has been taken in by a scam. They’ve been persuaded to keep the work secret to protect it, or because other scientists will misuse it, or something — but what they’re really protecting it against is fact-checking.

    That seems likely. Don’t know if there is a tie-in but for instance Silicon Valley venture capitalist Peter Thiel has gotten at least some negative press for supporting research into life extension via blood transfusions from young people.

    On DARPA and stealth: didn’t that research start at least a decade earlier with the SR-71?

  4. @Stoic Cynic: I don’t think that the SR-71 had any stealth (i.e., radar-evading) technology; it just flew so high and so fast that there was literally nothing that could catch up with it – it was designed solely for reconnaissance, not combat. The pilots had to wear what for all intents and purposes were spacesuits, and had to remain inside the airplane for ~ 2 hours after landing waiting for the aircraft skin to cool off to a safe temperature.

    High speed and altitude were key design points but so was stealth. The weird curves are designed to reduce radar cross section. It also had radar absorbing paint. From a Lockheed-Martin article:

    A Stealthy Pioneer
    Reducing the size of the Blackbird’s radar image meant an even further reduction in the likelihood that the plane would be perceived and shot down. Though the initial test results were good, rumors of Soviet radar advances led the U.S. government to ask for an even smaller radar profile.

    Surfaces had to be redesigned to avoid reflecting radar signals, the engines moved to a subtler mid-wing position, and a radar-absorbing element was added to the paint. Then a full-scale model of the Blackbird was hoisted on a pylon for radar testing at a Skunk Works’ secret location in the Nevada desert. With tests carefully scheduled to avoid Soviet satellite observations, the results were impressive: The Blackbird model, more than 100 feet in length, would appear on Soviet radar as bigger than a bird but smaller than a man. The team had succeeded in reducing radar cross section by 90 percent

  7. “That seems likely. Don’t know if there is a tie-in but for instance Silicon Valley venture capitalist Peter Thiel has gotten at least some negative press for supporting research into life extension via blood transfusions from young people.”

    Which reminds me of what the government came up with after the Howards fled in “Methuselah’s Children.”

  8. @Stoic Cynic: Cool! I did not know that. The Blackbird is still the most amazing-looking aircraft ever built; it’s hard to believe it was designed in the late 50s.

    Wow, shades of Spinrad’s Bug Jack Barron!

    (I was actually coming to suggest the possible link with BJB…I didn’t realize that there might be actual facts that would reinforce that possibility.)

  10. Well, let’s start with the first success that has really cemented DARPA’s reputation today.

    Well, that we know of…

  11. Ed Green: I might get a lot of hits on something titled, “DARPA Successes That We Don’t Know About.” Of course, those people would never come back again after looking at the blank page….
