Researching how to stop asteroids from “just dropping in”

Filed under: Europe, Science, Space, Technology — Tags: , , , — Nicholas @ 10:08

Brid-Aine Parnell in The Register on some of the technologies being explored to reduce or eliminate the chance of unpleasantly close encounters with celestial objects:

A new international consortium has been set up to figure out what Earthlings could do if an asteroid came hurtling towards the planet on a path of imminent destruction.

The project will look at three methods of averting disaster: the Hollywood-sanctioned solutions of sending up a crack team of deep drillers with a nuclear bomb to sort it out, or frantically hurling of all our nukes at it; dragging it to safety with a Star Trek-inspired tractor beam; or hitting it with something we have more control over, like a spaceship.

Sporting the cool moniker NEOShield, the project will explore the possibilities for kinetic impactors, gravity tractors and blast deflection as ways to save our planet from oblivion.

[. . .]

“In the light of results arising from our research into the feasibility of the various mitigation approaches and the mission design work, we aim to formulate for the first time a global response campaign roadmap that may be implemented when an actual significant impact threat arises,” NEOShield boldly stated.

The anti-Moonbase chorus

Natalie Rothschild on the (non-political) opposition to the very notion of a manned space program:

Suspicion towards space exploration is not new, of course. Since the 1970s, it has variously been decried as a danger to peace and security, as a chauvinist enterprise, as a wasteful pursuit and as a threat to the environment. Yet pessimism and indifference to space discoveries are at an all-time high today. This became clear in the reaction — or lack of reaction, rather — to NASA’s announcement in December 2009 that water had been discovered on the moon. As Sean Collins pointed out on spiked at the time, this was ‘a giant leap towards fulfilling one of our collective fantasies, something only dreamed about in science fiction: humans living somewhere other than Earth’. It also made the moon a more likely base for manned missions to other parts of the solar system and NASA suggested the lunar water could hold a key to the history and evolution of the solar system. Yet, as Collins pointed out then, neither online pundits nor the mainstream media nor the authorities made a big deal out of the ground breaking discovery.

Seen in this context it was no surprise that Gingrich’s boasts were ridiculed. His plans for a space colony might have sounded like a good idea when he touted it to Florida’s struggling Space Coast. After all, when the Obama administration cancelled George W Bush’s plans to return American astronauts to the moon by 2020, it prompted protests from the communities that depend on NASA for their livelihood as well as from Apollo veterans. But it was no surprise that he was met with put-downs from most other quarters and that his ideas were entirely dismissed.

By and large, human achievements tend to be downplayed today. Exploring the unknown is seen as, at best, impractical and, at worst, reckless. When it comes to manned space exploration, the prevailing attitude is ‘been there, done that’. That’s why there’s been an unwillingness to separate Gingrich’s more wacky ideas — launching a new space race and establishing a permanent American outpost on the moon within eight years — from his sensible reminder that if we are to have any chance of making new discoveries and advances in the near or distant future, then we need to be willing at least to imagine that it’s possible and desirable to overcome the limits we face today.

Coffee may help in weight loss (but your gallon-sized hippy-dippy frappy latté certainly won’t)

Filed under: Health, Science — Tags: — Nicholas @ 12:30

A brief news item at 680news.com:

New research has found coffee may have many health benefits, including moderate weight loss.

James O’Keefe, a cardiologist with St. Lukes medical system, says a review of some of the largest studies on coffee consumption found it contains anti-oxidants which are widely believed to be good for your health.

He added that, despite the fact that coffee has been shown to increase blood pressure and heart rate, the caffeine can actually aid in the prevention or delay of Type 2 diabetes.

Compounds in your morning cup of joe can increase insulin and reduce inflammation, as well we increasing your metabolism at the cost of no calories.

Just for the folks who think coffee is something you pay $5.00 plus tax for at your local Starbucks: this is the no-cream, no-sugar, no-syrup, no-whipped-cream, no-sprinkles hot beverage you don’t need to buy in imaginatively named cup sizes.

Thanks for the memories, oligomers

Filed under: Health, Science — Tags: — Nicholas @ 12:21

A recent discovery at the Stowers Institute for Medical Research may indicate fruitful directions for further research on memory loss:

Memories in our brains are maintained by connections between neurons called “synapses.” But how do these synapses stay strong and keep memories alive for decades? Neuroscientists at the Stowers Institute for Medical Research have discovered a major clue from a study in fruit flies: Hardy, self-copying clusters or oligomers of a synapse protein are an essential ingredient for the formation of long-term memory.

The finding supports a surprising new theory about memory, and may have a profound impact on explaining other oligomer-linked functions and diseases in the brain, including Alzheimer’s disease and prion diseases.

“Self-sustaining populations of oligomers located at synapses may be the key to the long-term synaptic changes that underlie memory; in fact, our finding hints that oligomers play a wider role in the brain than has been thought,” says Kausik Si, Ph.D., an associate investigator at the Stowers Institute, and senior author of the new study, which is published in the January 27, 2012 online issue of the journal Cell.

To help kids stay healthier, don’t be a clean fanatic

Filed under: Health, Science — Tags: , , — Nicholas @ 12:08

I’ve suspected for quite a while that the “epidemic” of food allergies and other ailments among today’s children was related to the extremely hygienic conditions of modern homes (that is, kids’ immune systems were insufficiently stressed by exposure to germs, which meant higher risk of immune system over-reaction later in life). I’m not a scientist, so my suspicion was just based on less-than-statistically valid observation of my son and his friends while they were growing up — the kids with the most sterile home environments did seem more likely to have serious allergy issues come up later.

I could have been on the right track, after all:

I do wonder, however, whether we’re all becoming a bit too paranoid about germs. I include my own family in this group. Once we left the doctors’ office, for example, my wife and I encouraged our children to use a hand sanitizer. When our kids were toddlers our house had alcohol wipes and Purell vials all over the place. But is all this washing and disinfecting really necessary? Is it proactive prevention? Or overly paranoid fear?

That, at least, is the thinking behind the “hygiene hypothesis,” a school of thought first proposed by David P. Strachan in 1989, and now experiencing a resurgence that’s probably a response to society’s mania for cleanliness. Strachan’s original study sought to explain why British kids with greater numbers of older siblings had fewer incidences of hay fever, speculating that perhaps it could be the fact kids with lots of older siblings tend to be exposed to greater numbers of germs. While it was greeted with skepticism early on, Strachan’s theory has since been confirmed. In fact, in the decades since, greater exposure to germs early in life has also been associated in epidemiological studies with lower levels of asthma, some allergies and even such autoimmune diseases as type-1 diabetes and multiple sclerosis.

[. . .]

“These data support the idea that the greater diversity of microbial exposure among children who live on farms is associated with the protection from the development of asthma,” study researchers reported, speculating that microbial exposure may encourage development of immune system cells that in turn suppress the production of the sort of immune-system cells that trigger asthmatic reactions. Researchers’ next hope to determine which microbes are most responsible for preventing asthma — and that, perhaps, may lead to new therapies, such as targeted microbe exposures, for the dreaded respiratory malady.

More broadly, the study is a reminder that humans have been living and fighting off germs for tens of thousands of years. Particularly when we’re young, germs serve an important purpose for the development of the immune system. By depriving our children of exposure to germs, we may be depriving them the benefits of a process the human body has evolved over aeons, a process that helps to create healthy and allergy-free adults.

DARPA appoints former astronaut to lead 100-year starship project

Filed under: Space, Technology, USA — Tags: , , , — Nicholas @ 09:56

Brid-Aine Parnell works the Star Trek angle on the appointment of former NASA astronaut Dr Mae Jemison as the head of the 100-year Starship project:

The agency had not responded to a request for comment at the time of publication, and has not yet announced the appointment publicly.

Dr Jemison, who has a degree in chemical engineering and a doctorate in medicine, was the science mission specialist on the STS-47 Spacelab-J in 1992 and logged over 190 hours in space.

As well as being a bona fide boffin, Jemison also spent time in the IT trenches, working in computer programming, among other things, before joining NASA.

She’s also no stranger to the ideas behind a starship, since, as a long-time Star Trek fan, she had a bit part in one episode of Star Trek: The Next Generation.

The episode, entitled Second Chances, must surely go down as evidence of her remarkable patience and forbearance, since it featured the two most irritating TNG characters, Commander Riker and Deanna Troi, rather prominently.

Are creative people also more likely to be “creative” with the truth?

Filed under: Science — Tags: , , , — Nicholas @ 10:51

Melissa Leong on a recent study:

Francesca Gino’s new study, which links creativity to dishonesty, opens with a quote from 18th-century French philosopher and art critic Denis Diderot: “Evil always turns up in this world through some genius or other.”

Gino is not suggesting, as some artists at the time complained, that creative people are evil. But she is saying that, according to her research, creative people are more apt to cheat, lie and justify their evil. Gino, associate professor of business administration at Harvard University, spoke to the Post about her study, co-authored by Dan Ariely, a behavioural economist at Duke University. (Their findings were published in the Journal of Personality and Social Psychology last month.)

Guardian study finds that August rioters were motivated by Guardian editorials

Filed under: Britain, Economics, Government, Law, Media — Tags: , , , — Nicholas @ 09:16

Brendan O’Neill on the recent study, carried out by the London School of Economics and the Guardian:

Well, that’s convenient, isn’t it? A four-month Guardian/London School of Economics study into the riots that rocked English cities in August has found that the rioters were pretty much Guardian editorials made flesh. Concerned about government cuts, annoyed by unfair policing, shocked by social inequality and outraged by the MPs’ expenses scandal, it seems the young men and women who looted shops and burnt down bus stops weren’t Thatcher’s children after all — they were Rusbridger’s children, the moral offspring of those moral guardians of chattering-class liberalism.

This is a blatant case of advocacy research, of researchers finding what they wanted to find, or at least desperately hoped to find. For months now, the Guardian has been publishing articles arguing that the rioters were politically motivated, under headlines such as ‘These riots were political’ and with claims such as ‘the looting was highly political’ and the riots were a protest against ‘brutal cuts and enforced austerity measures’. And now, lo and behold, a Guardian study, Reading the Riots, has discovered that the rioters were indeed ‘rebels with a cause’, with 86 per cent of the 270 rioters interviewed claiming the violence was caused by poverty, 85 per cent arguing that policing was the big issue, and 80 per cent saying they were riled by government policies. Reading this study, we are left to marvel either at the extraordinary perspicacity of Guardian writers, or at their ability to carry out research in such a way that it confirms their own political preconceptions.

This study looks less like a cool-headed, neutral piece of sociology, and more like a semi-conscious piece of political ventriloquism, where rioters have been coaxed to mouth the political beliefs of the middle-class commentariat. This is not to say the Guardian and LSE researchers have been purposely deceitful, inventing evidence to suit a political thesis. Advocacy research is more subtle and less conscious than that. It involves a kind of inexorable pursuit of facts that fit and evidence that helps bolster a pre-existing conviction. So mental-health charities keen to garner greater press coverage always find high levels of mental illness, children’s charities that want to raise awareness about child abuse always find rising levels of child neglect, and now Guardian researchers who want to show that they’re right to fret about Lib-Con policies and outdated policing have found that these are burning issues amongst volatile English yoof, too.

Moral hazard invades the scientific sphere

Filed under: Economics, Government, Media, Science — Tags: , , — Nicholas @ 12:23

Bill Frezza looks at an unanticipated consequence of pouring more government money into the sciences:

Science and the scientific method are the jewels in the crown of Western civilization. The ascertainment of facts, construction of reproducible experiments, development of falsifiable theories, impartial training and meritocratic advancement of practitioners, and — most importantly — integrity of the publication process by which a well established body of truth can be confidently assembled all underpin the respect accorded to science by the citizenry. In modern times, this respect translates into tax dollars.

Unfortunately, today those tax dollars are corrupting the process. Unprecedented billions are doled out by unaccountable federal and state bureaucracies run by and for the benefit of a closed guild of practitioners. This has created a moral hazard to scientific integrity no less threatening than the moral hazard to financial integrity that recently destroyed our banking system.

According to a report in Nature Reviews Drug Discovery, nearly two-thirds of the experimental results published in peer-reviewed journals could not be reproduced in Bayer’s labs. The latest special issue of Science is devoted to the growing problem of irreproducibility. The Wall Street Journal reports that Amgen, Pfizer, and others have abandoned research programs after spending hundreds of millions pursuing academic research that could never be replicated.

Is “innovation” today’s buzzword equivalent of “excellence”

Filed under: Government, Technology — Tags: , , , — Nicholas @ 09:07

Stephen Gordon thinks that the term “innovation” is well on the way to being just another way of saying “corporate handout”:

The theory of economic growth includes roles for such well-defined concepts as investment, human capital, research and development, productivity, and technical progress. I don’t know where innovation fits into this. My guess would have been that innovation is another name for R&D, but apparently there’s an ineffable distinction between innovation and R&D.

There are well-known policy instruments at the government’s disposal for increasing investment in human and physical capital and for increasing R&D activities. (Their relative effectiveness is another question.) But so far, the only proposals I’ve seen for an innovation policy consist of programs in which governments give money to deserving firms. This is problematic on a couple fronts.

Firstly, there are already many — too many — ‘economic development’ programs whose purpose is to channel public money to companies that enjoy the favour of the government. It’s hard to believe we need more of them.

“[Fill-in-the-blank] is now a clear and present danger”

Filed under: Environment, Health, Media, Science — Tags: , , , , — Nicholas @ 12:07

Andrew Orlowski explains how we keep falling for junk science through media exposure:

Firstly. An obscure researcher or scientist will make a dramatic claim.

The media picks up on this, and a reporter is assigned to the story. The reporter will have no scientific background — but looks to the state and the bureaucracy to do something. Anything.

The hapless minister is then hauled on to explain the inaction. He will be intelligent — he is likely to have a PPE from Oxford, like the presenter — but no specialist knowledge. He, too, trusts the scientists.

A pledge is then made to increase funding for the scientist who makes the claim.

A pledge is also made to act — by introducing legislation or other regulations. Perhaps a task force or committee will also be involved:

The biggest threat to the environmental movement

Filed under: Economics, Science, Technology — Tags: , , — Nicholas @ 09:50

No, it’s not some ferociously polluting corporation, or a dangerously powerful conservative politician or a candidate for the GOP nomination in the United States. It’s algae:

“We can engineer, humbly, like we have been domesticating plants for a long time,” one scientist told me. “We engineer the algae to do biochemically something quite different to what they’d be doing in the wild: they still take photons from the sun, and via biology, turn it into a useful captured molecule. We have them doing something similar but with stunning efficiency: it’s 40 to 100 times more efficient,” says Elbert Branscomb, chief scientist to the US Department of Energy.

There are (at least) around 60 startups hoping to produce oil and diesel biologically, with accelerated fermentation or photosynthesis techniques to produce an end product that is 100 per cent compatible with the existing infrastructure. Some, for example, tweak the algae to make them do photosynthesis anything from 40 to 100 times more efficiently. LS9 received $30m in funding and has a one-step process to convert sugar to create renewable petrol. It expects production within five years. If oil prices remain high, say over $40 or $50 a barrel, then it’s viable.

So why is this the biggest threat to the environmental movement?

But the greatest challenge cheap hydrocarbons poses is for people whose outlook is founded on what I call “End Times logic”. The most successful political movement in recent years is environmentalism, which expanded from specific concerns about pollution and conservation into an all-encompassing worldview, complete with very preachy appeals to changing parts of our lifestyles.

These ranged from “Don’t flush the loo too often”, to “Don’t fly for a weekend break”, to “Eat less red meat”. Very few politicians have felt courageous enough to contradict this. And the movement has achieved its ascendancy through urgent, apocalyptic appeals, rather than using calmer methods of rational persuasion which involve costs and benefits to be totted up. These new energy sources pose a profound problem: they saves the planet, and we carry on with minimum disruption.

I expect that one effect will be that environmentalism will become much more about everyday concerns such as pollution, and conservations again, back to where it started. But it grew into a vacuum, after the end of the Cold War, when great political ideas seemed to lose credibility. As a way of driving the political agenda, it will become currency without value. Buzzwords such as “sustainability”, founded on a resource-constrained view, will no longer be credible. People will simply laugh at them.

The inspirational power of science fiction

Filed under: Media, Technology — Tags: , , , , , , — Nicholas @ 10:36

Neal Stephenson on the ability of science fiction to inspire:

In early 2011, I participated in a conference called Future Tense, where I lamented the decline of the manned space program, then pivoted to energy, indicating that the real issue isn’t about rockets. It’s our far broader inability as a society to execute on the big stuff. I had, through some kind of blind luck, struck a nerve. The audience at Future Tense was more confident than I that science fiction [SF] had relevance — even utility — in addressing the problem. I heard two theories as to why:

1. The Inspiration Theory. SF inspires people to choose science and engineering as careers. This much is undoubtedly true, and somewhat obvious.

2. The Hieroglyph Theory. Good SF supplies a plausible, fully thought-out picture of an alternate reality in which some sort of compelling innovation has taken place. A good SF universe has a coherence and internal logic that makes sense to scientists and engineers. Examples include Isaac Asimov’s robots, Robert Heinlein’s rocket ships, and William Gibson’s cyberspace. As Jim Karkanias of Microsoft Research puts it, such icons serve as hieroglyphs — simple, recognizable symbols on whose significance everyone agrees.

Researchers and engineers have found themselves concentrating on more and more narrowly focused topics as science and technology have become more complex. A large technology company or lab might employ hundreds or thousands of persons, each of whom can address only a thin slice of the overall problem. Communication among them can become a mare’s nest of email threads and Powerpoints. The fondness that many such people have for SF reflects, in part, the usefulness of an over-arching narrative that supplies them and their colleagues with a shared vision. Coordinating their efforts through a command-and-control management system is a little like trying to run a modern economy out of a Politburo. Letting them work toward an agreed-on goal is something more like a free and largely self-coordinated market of ideas.

Good news for (some) soldiers

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 13:15

David Pugliese reports on the US Army’s work on a new, significantly lighter, Squad Automatic Weapon:

“We are using cased telescoped ammunition which uses a strong plastic case instead of a traditional brass case,” said Kori Phillips, a systems management engineer with ARDEC.

Weight reduction for the weapon was achieved by designing the new weapon platform using the latest materials technologies as well as modeling and simulation to achieve minimal weight without compromising performance.

With a basic load of 1,000 rounds, the LSAT light machine gun and its cased telescoped ammunition is 20.4 pounds lighter than a traditional SAW with the same amount of standard, brass-cased ammunition.

[. . .]

“The cased telescoped ammo still provides the same muzzle velocity, range and accuracy as the brass-cased ammo,” Phillips said. “We’re not sacrificing lethality for weight. The plastic case does the same job.”

In addition to significant weight savings, the LSAT is designed to provide other advantages over the current SAW. With a rotating chamber design, the cased telescoped light machine gun improves reliability.

“We’ve avoided the common problem of failure to feed and failure to eject,” Phillips said. “In the current SAW system, that’s one of the places where you primarily have failures and malfunctions.”

Of course, if the new ammunition works well for the SAW, it’ll certainly be adapted for other small arms (in a hot combat zone, you never have “too much” ammunition available, but you often have “too little”).

Perhaps they should call themselves the Canadian Fundraising Society?

Filed under: Bureaucracy, Cancon, Health — Tags: — Nicholas @ 12:21

As it appears that they only have a sideline in cancer research these days:

An Ontario cancer researcher is concerned that the Canadian Cancer Society has proportionally shifted funding away from research and is spending more of its dollars on fundraising and administration costs.

“Most scientists don’t realize that the budget has been going up and up, and donations have been growing, but the budget for research has been shrinking,” said Brian Lichty, a researcher at McMaster University who is looking into treating cancer with viruses that kill tumours. “So they are surprised and disappointed when they find out that this is the case, and the trend.”

CBC’s Marketplace analyzed the Canadian Cancer Society’s financial reports dating back a dozen years. It discovered that each year, as the society raised more dollars, the proportion of money it spent on research dropped dramatically — from 40.3 per cent in 2000 to under 22 per cent in 2011.

The amount of money spent on research has increased slightly over the years, but as a portion of the Cancer Society’s growing budget, it’s almost been cut in half.
