Champagne serving tip

Filed under: Randomness, Science, Wine — Nicholas @ 00:18

Shereen Dindar warns us that even though common sense has been vindicated on this issue, we shouldn’t get too cocky:

We now have a scientific study to confirm the widely accepted ritual of pouring bubbly down the side of a flute before drinking it actually makes sense.

Scientists in France found that pouring bubbly in an angled way and chilling the beverage in advance is best for preserving its taste, fizz and aroma.

Gérard Liger-Belair and colleagues — who published their findings in the Journal of Agricultural and Food Chemistry — studied carbon dioxide loss in champagne that was poured straight down the middle of a glass, as well as, down the side of an angled glass. They found that pouring champagne down the side preserved up to twice as much carbon dioxide.

I’m not a big Champagne fan — I don’t mind sparkling wines, but generally there are better values in Spanish Cava than in French Champagne — but no matter what your preference in bubbly, do yourself a big favour and serve your sparkling wine in the right kind of glass. Don’t use the caterer’s special — what they laughingly call a Champagne glass is almost ideally suited to producing the worst the wine has to offer. Use a proper Champagne “flute”, a tall narrow glass that concentrates the aromas (and the bubbles), not a wide, flat glass that dissipates ’em quickly.

The search for the geekiest beer

Filed under: Randomness, Science — Tags: — Nicholas @ 07:27

Betsy Mason reports on the ongoing search for the Venn diagram showing the intersection of microbrewing and science geeks:

I’ve already proven the connection between beer and geologists, but the number of brews out there with awesomely geeky science names suggests that the beer-science link is even more primordial. After stumbling across a few of these, like Shale Ale (named for the Burgess Shale, a famously fossiliferous outcrop) and Homo Erectus (an IPA made by Walking Man Brewing), I decided the matter required further investigation.

With the help of my friends and Twitteronia, I tracked down a bunch more science-geek beers, and a few with super-geeky tech themes (this is Wired, after all). I managed to get seven of them into Wired HQ, because, let’s be honest, this was all just another elaborate excuse to make drinking beer part of my job.

Sadly, I couldn’t get my hands on some of the geekiest beers. A few were short runs for special occasions, like The Empire Strikes Back All-English IPA and Galileo’s Astronomical Ale (tagline: Theoretically the best beer in the universe), brewed by astronomy geek Ken Grossman of Sierra Nevada Brewing Company to celebrate the 400th anniversary of the telescope. And some are seasonal, like 21st Amendment’s Spring Tweet, a beer brewed for Twitter (which brings up the obvious question: Where’s Wired’s beer?)

Hey kids, are your parents uptight about you having sex?

Filed under: Britain, Health — Tags: , , — Nicholas @ 07:10

That’s to be expected. They’re even more uptight about their parents having sex:

Over the last few months there have been numerous headlines about the sex lives of the over-50s — almost all negative. The HIV infection rate in this group has doubled, we are told. The numbers of over-50s suffering from chlamydia, syphilis, gonorrhoea, herpes and genital warts is growing. One doctor even wrote about his shock at treating the sexual diseases of what he called “cheerfully promiscuous” baby boomers.

It is true there are probably some people at middle age who mistakenly think their sexual partners are above suspicion, and others who did not enter their dating lives using condoms. Safer sex practices may not come so easily for them, yet the prominence and style of these articles underscores the sexual ageism that pervades our society. Where are the positive messages about the sex lives of people in their 50s, 60s, 70s and beyond? Do we ever hear the truth about how sexually vibrant they can be — without an attached warning about physical dangers and moral pitfalls? Sex among elders is surely one of the greatest sexual taboos in western society.

Not news: many Americans prefer religious to scientific answers

Filed under: Religion, Science, USA — Tags: , , — Nicholas @ 09:35

Scientific American pretends to be surprised by these findings:

When presented with the statement “human beings, as we know them today, developed from earlier species of animals,” just 45 percent of respondents indicated “true.” Compare this figure with the affirmative percentages in Japan (78), Europe (70), China (69) and South Korea (64). Only 33 percent of Americans agreed that “the universe began with a big explosion.”

Consider the results of a 2009 Pew Survey: 31 percent of U.S. adults believe “humans and other living things have existed in their present form since the beginning of time.” (So much for dogs, horses or H1N1 flu.) The survey’s most enlightening aspect was its categorization of responses by levels of religious activity, which suggests that the most devout are on average least willing to accept the evidence of reality. White evangelical Protestants have the highest denial rate (55 percent), closely followed by the group across all religions who attend services on average at least once a week (49 percent).

I don’t know which is more dangerous, that religious beliefs force some people to choose between knowledge and myth or that pointing out how religion can purvey ignorance is taboo. To do so risks being branded as intolerant of religion.

Bereaved Ohio family suing Norfolk Southern for failing to change laws of motion

Filed under: Law, Railways, Science, USA — Tags: , — Nicholas @ 21:28

Sorry for their loss, but suing the railroad because the train crew didn’t change the laws of physics to avoid hitting Matthew Johnson as he ran along a trestle won’t work:

The family of a man who was hit by a train while jumping off a trestle into a river two years ago is suing the railroad and a local canoe center, according to documents filed in Clark County Common Pleas Court Thursday, Aug. 5.
Matthew Johnson, 21, died Aug. 10, 2008 while he and three other people were standing on a train trestle between Old Mill Road and the Masonic Temple grounds.
Johnson’s mother, Carol Johnson, of West Carrollton, has filed suit against Norfolk Southern Railway Company and Aaron’s Canoe and Kayak Center, Springfield.

[. . .]

Among the allegations listed in the complaint:
• The canoe company “knew or should have known that individuals frequently went onto the train trestle and jumped into the Mad River.”
• Train conductors “failed to timely and effectively stop the train,” causing Johnson’s death.
• The railroad was negligent in its duty to “maintain and equip its train with all necessary navigational and/or safety devices.”

Just so we’re clear here: there is no “navigational and/or safety device” ever conceived that can safely stop a multi-thousand ton freight train in less than hundreds of metres of distance. Physics does not play favourites — once that much mass is in motion, it takes a lot of energy to stop it without catastrophic dis-assembly.

Examining DNA testing from the client’s point of view

Filed under: Bureaucracy, Government, Health, Media, Science — Tags: , , , — Nicholas @ 07:19

Mary Carmichael is writing a multi-part series about DNA testing:

On July 22, Congress held a hearing on direct-to-consumer (DTC) genetic tests, services that analyze your DNA and interpret the results in exchange for a few hundred bucks — no doctor necessary. The hearing could have been a thoughtful national conversation about science, business, and ethics. Alas, it devolved instead into a series of gotcha moments, starring a General Accounting Office sting operation that came off like a cross between the ACORN videos and the world’s worst ad for snake oil.

Time and again, on tape, an undercover agent called up an unidentified testing company and asked an ill-informed question. (“Is it OK if I stop taking my cholesterol meds and instead take the nutritional supplements you sell? If I can manage to get hold of my fiancé’s saliva without him knowing, will you run it through your machines so I can surprise him with the ‘gift’ of his own data?”) And time and again, the phone rep sank to the occasion and made the company look awful. (Sure, lay off the pills and take our supplements! Of course we’ll analyze your fiancé’s spit without his permission even though that’s illegal, unethical, and weird!)

I listened to the tape several times the day it was released, despairing at the way people were taking advantage of gullible, albeit fictional consumers, which was clearly how the congressmen who held the hearing wanted me to react. Then I started to worry about something else. How much time did I even have left to decide whether I was going to take a test myself? Even before the hearing, the FDA had announced its plans to regulate all DTC genetic tests, possibly so heavily as to keep them off the market; the hearing was just the sort of thing that could push it to move faster. What if, by the time I finally decided if I wanted one of these tests, I couldn’t buy one anymore? My credit card was sitting next to my laptop. I did something that in retrospect seems a bit rash. There’s a DNA-collection kit on my desk now, taunting me — because although I bought the thing, I still can’t decide whether I actually want to use it.

The sheer volume of misinformation on DNA testing — combined with public belief in the amazing accuracy of DNA testing (probably induced by watching too many crime investigation TV shows) — leaves the legitimate companies in an awkward situation. The actual DNA self-tests don’t tell you what you might expect, and can tell you things you don’t want to know. Politicians jumping in now (at the prompting of bureaucrats who want more power to regulate) will only make the situation more confused.

Canada’s (lack of) abortion rules

Filed under: Cancon, Government, Health, Law — Tags: , , , , — Nicholas @ 09:31

Apparently lots of Canadians think that the country’s laws are far more restrictive of abortion than they really are:

Two-thirds of Canadians do not know that Canada has no abortion law, according to a new poll that indicates Canadians are woefully misinformed about a landmark ruling in the country’s history.

The poll, which asked 1,022 Canadian adults about their understanding of the country’s abortion regulations, found that just 22% of Canadians correctly identified a woman’s right to an abortion with no governmental restrictions. Canada has not had legislated abortion rules since 1988, making the country an “absolute outlier” on the issue, according to a medical ethicist.

“There’s really only a very small number of Canadians that correctly identify the current situation in Canada,” says pollster Jaideep Mukerji, who worked on the Angus-Reid poll, which was released on Tuesday. “That could be problematic.”

This was highlighted over the last couple of months, with the government and opposition wrangling over Stephen Harper’s initiative to increase funding for maternal health in the developing world. Because opinions widely differ over what the law covers in Canada, it was easy for the opposition to portray Harper’s plan as being ideological rather than humanitarian due to the exclusion of abortion.

Canadians don’t want to re-open the debate, although most appear to want more restrictions in place.

The Chevy Volt should be called the milliVolt

Unlike the fond hopes of politicians, the Chevrolet Volt isn’t quite the revolutionary breakthrough in transportation we’ve been promised:

The electric Chevrolet Volt will roll off the assembly lines next year.

The price is a staggering $41,000 US — a BMW price for a Chevy.

Price isn’t the only clanger here. The car can only travel for about 65 km on an electric charge. After that, it fires up a gas-powered engine like everything else on the road. So much for reduce, reuse, recycle — this is a car with two engines. Hummers only have one.

And Hummers don’t have a massive battery that’s about as easy to dispose of when the car’s finally done as a tub of PCBs.

The Volt is more than twice as expensive as its non-electric counterparts. It can’t drive far enough to get from one city to another. And when your Volt has a low battery, it literally takes hours to recharge. So maybe it will ready to go when you need it. Maybe it won’t.

I checked; the name “Smart Car” is already taken, but “Dumb Car” is available.

GM knows this. Which is why it plans to produce only 10,000 of them next year.

I’m very much in favour of an economical electric car: the Volt doesn’t meet that definition. It’s been rushed to market for political, not for economic reasons. It’ll be kept in the market regardless of sales figures for the same reason: it allows Barack Obama and senate leaders to point at the Volt as tangible proof that they care about the environment and reducing American dependence on foreign oil.

Japan’s centenarians are going missing

Filed under: Bureaucracy, Health, Japan — Tags: — Nicholas @ 07:36

After the discovery that the oldest man in Tokyo had actually been dead for years, it should come as no surprise that the oldest woman in Tokyo has apparently been missing for decades:

Fusa Furuya, aged 113, had been registered as living with her daughter.

But the daughter says she has not seen her mother since the 1980s.

According to government data, there are more than 40,000 centenarians in Japan. But the discoveries in Tokyo have cast doubt on the accuracy of the figures.

Despite being reputed to be Tokyo’s oldest woman, it appears no-one had bothered to check that Mrs Furuya was still alive — until now.

Local council officials have been visiting the very elderly after the body of Sogen Kato, thought to be Tokyo’s oldest man, was found last week.

The police believe he had been dead for more than 30 years.

When officials went to Ms Furuya’s home, they discovered that she had been missing for decades.

Unlike the earlier case, where the man’s family had continued to collect his pension, the family of Fusa Furuya don’t appear to have been involved in pension fraud . . . although you do wonder why they hadn’t noticed her being missing all this time.

QotD: Take experts’ advice with a pinch of salt

Filed under: Bureaucracy, Food, Health, Media, Quotations — Tags: , , , , — Nicholas @ 11:41

More and more, the history of dietary guidelines that our public-health authorities promulgate resembles the Woody Allen comedy Sleeper, in which the main character, awaking from a centuries-long slumber, learns that every food we once thought bad for us is actually good, starting with steak and chocolate. But you wouldn’t know that from government experts’ increasing efforts to nudge us into their approved diets. In 2006, New York City passed the nation’s first ban on the use of trans fats by restaurants, and other cities followed suit, though trans fats constitute just 2 percent of Americans’ caloric intake. Now the Bloomberg administration is trying to push food manufacturers nationwide to reduce their use of salt — and the nutrition panel advising the FDA on the new guidelines similarly recommends reducing salt intake to a maximum of 1,500 milligrams daily (down from 2,300 a day previously). Yet Dr. Michael Alderman, a hypertension specialist at Albert Einstein College of Medicine, observed in the New York Times that because sodium is an essential component of our diets, the city’s effort amounts to a giant uncontrolled experiment with the public’s health that could have unintended consequences. And in 2006, Harvard Medical School professor Norman Hollenberg concluded that while some people benefit from reduced salt intake, the evidence “is too inconsistent and generally too small to mandate policy decisions at the community level.”

BC government finds an issue to distract the media

Filed under: Cancon, Health, Law — Tags: , , , , — Nicholas @ 09:44

Adrian MacNair linked to this Vancouver Sun article, saying “”B.C. halts penis-arousal test for youth sex offenders” Say whaaaaaaatttt?”

A moratorium has been placed on tests done on B.C. youth sex offenders measuring their penis arousal in response to sexual stimuli after the province’s top child advocate launched an immediate investigation Wednesday.

The device in question is called a “penile plethysmograph” — or PPG. In a lab setting, it is attached to male genitals so technicians can measure changes in “penile tumescence” — essentially erections that reflect the state of arousal in subjects shown photographs of adults, children and even babies in varying states of undress while at the same time being read a story that describes coercive or forced sexual activity.

So, until it came to light, the government was showing provocative images and reading pornographic stories to teenage boys to find out if they got erections during the process? Would anyone be surprised to find that teenage boys found this whole exercise sexually arousing? Teenage boys are hard-wired to find all sorts of things sexually arousing!

The point of the test is to reportedly predict whether offenders have gained control of their deviant arousal patterns through treatment or if they have not learned how to suppress deviance and will be a strong risk for re-offending.

Again, we’re talking about teenage boys . . . I’d be more suspicious if they found that one of them was managing not to react to such stimulus!

Okay, yes, I’m unfairly stereotyping, at least to some degree. But this sort of “test” or “experiment” would be flagrantly illegal if it were being done by anyone other than a government-funded health organization, wouldn’t it?

Replacing one impossible ideal with another

Filed under: Britain, Health, Media — Tags: , , , — Nicholas @ 09:23

Colby Cosh linked to this Guardian article, saying “I’m afraid she’s right. ‘Thin’ is something every girl can at least strive for. Only God can make Christina Hendricks.”

When it comes to the ideal female body-shape the pipe cleaner is out, the hourglass is in — or at least it will be if the new equalities minister, Lynne Featherstone, manages to chisel out her will on the perfect body image.

“In the autumn the minister will convene the first of a series of roundtable discussions with members of the fashion industry, including magazine editors, models and advertisers, to discuss how to boost body confidence among the young,” the Sunday Times reported yesterday.

One might think that one of the first steps to boost such confidence might be to abolish school weigh-ins and make puppy fat a normal rite of passage rather than the subject of a health warning via the National Child Measurement Programme. (Can any woman think of anything more likely to have produced a fear of being on the chunky side than turning up to school one morning and being plonked on a set of scales?)

While I’m happy to have any excuse to post a photo of the delightful “YoSaffBridge”, this is another example of Nanny State thinking: (some) women have body image issues, therefore we must spring into action and fix it.

Rather than replacing the old impossible images with new impossible images (as the creative director of Harper’s Bazaar pointed out, the fashion industry exists to create the fantasy you’ll never live up to) an equalities minister should throw out all notions of obsessing about feminine beauty and concentrate on helping young girls think about the size of their achievements rather than the flatness of their navels, and the scale of their ambitions rather than — in Joanie’s case — the rather spectacular power of their bosoms.

First results from new study around Stonehenge

Filed under: Britain, Europe, History, Science — Tags: , , , — Nicholas @ 07:27

A new study of Stonehenge by the University of Birmingham and Vienna’s Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology has made its first major discovery:

Archaeologists have discovered a second henge at Stonehenge, described as the most exciting find there in 50 years.

The circular ditch surrounding a smaller circle of deep pits about a metre (3ft) wide has been unearthed at the world-famous site in Wiltshire.

Archaeologists conducting a multi-million pound study believe timber posts were in the pits.

Project leader Professor Vince Gaffney, from the University of Birmingham, said the discovery was “exceptional”.

The new “henge” — which means a circular monument dating to Neolithic and Bronze Ages — is situated about 900m (2,950ft) from the giant stones on Salisbury Plain.

I imagine, given how many times Stonehenge has been mucked about with by earlier enthusiasts, there must be much misleading data has to be sifted and re-sifted before any definite discoveries can be announced. Stonehenge has been fascinating people for centuries and there are probably lots of amateur investigations that may well have made the situation more confusing (think of a sixteenth century equivalent of Indiana Jones or Lara Croft with a nose for treasure).

Addressing the science and technology gender gap

Filed under: Economics, Education, Liberty, Science, Technology — Tags: , , , — Nicholas @ 09:32

It must be the start of the silly season, as lots of words are being flung around about the low number of women in science, technology, engineering, and math (STEM). The numbers are well short of gender parity, which some are latching on to as prima facie proof of misogyny, prejudice, and deliberate stunting of women’s career choices. Legislative and regulatory “fixes” are being suggested. Not so fast, says Eric S. Raymond:

Let’s get one shibboleth out of the way first: Larry Summers was right to be skeptical about the prospects for “equality” in STEM (science, technology, math, engineering) fields in general. Just the difference in dispersion of the IQ curves for males and females guarantees that, let alone the significant differences in mean at spatial visualization and mathematical ability. Removing all the institutional, social and psychological barriers will not achieve a 1:1 sex ratio in these fields; the best we can hope for is a large, happy female minority — that is, as opposed to a small and unhappy one.

[. . .]

I don’t mean to deny that there is still prejudice against women lurking in dark corners of the field. But I’ve known dozens of women in computing who wouldn’t have been shy about telling me if they were running into it, and not one has ever reported it to me as a primary problem. The problems they did report were much worse. They centered on one thing: women, in general, are not willing to eat the kind of shit that men will swallow to work in this field.

Now let’s talk about death marches, mandatory uncompensated overtime, the beeper on the belt, and having no life. Men accept these conditions because they’re easily hooked into a monomaniacal, warrior-ethic way of thinking in which achievement of the mission is everything. Women, not so much. Much sooner than a man would, a woman will ask: “Why, exactly, am I putting up with this?”

Correspondingly, young women in computing-related majors show a tendency to tend to bail out that rises directly with their comprehension of what their working life is actually going to be like. Biology is directly implicated here. Women have short fertile periods, and even if they don’t consciously intend to have children their instincts tell them they don’t have the option young men do to piss away years hunting mammoths that aren’t there.

Eric feels that the big problem (at least in computing) is that the field has become the modern sweatshop: better paid by far than sweatshops of the non-digital nature, but still the kind of work that only appeals to the obsessives, the ones who like to focus monomaniacally on goals. As a general rule, men are much more likely to accept this kind of work, as men tend to have a bias towards monomania that most women don’t.

There’s also the social aspect: geeks don’t talk to one another in the same way or for the same lengths of time as non-geeks do. They may communicate by email or instant messaging or other non face-to-face media, but conversation — unless it’s focused on the task at hand — isn’t a preferred activity during work hours (which, for a true geek, may be all the hours not spent sleeping or eating). Looking at that kind of environment doesn’t attract people who are well socialized and who are used to more interaction with co-workers.

As a comment on Eric’s post put it: “You’re saying the real “problem” with the gender ratios is not sexism, its that most women have more sense than we males do!”
