Submission Why It Was Easier to Be Skinny in the 1980s

schwit1 writes: A new study finds that people today who eat and exercise the same amount as people 20 years ago are still fatter.

A study published recently in the journal Obesity Research & Clinical Practice found that it's harder for adults today to maintain the same weight as those 20 to 30 years ago did, even at the same levels of food intake and exercise. The authors examined the dietary data of 36,400 Americans between 1971 and 2008 and the physical activity data of 14,419 people between 1988 and 2006. They grouped the data sets together by the amount of food and activity, age, and BMI.

They found a very surprising correlation: A given person, in 2006, eating the same amount of calories, taking in the same quantities of macronutrients like protein and fat, and exercising the same amount as a person of the same age did in 1988 would have a BMI that was about 2.3 points higher. In other words, people today are about 10 percent heavier than people were in the 1980s, even if they follow the exact same diet and exercise plans.

Submission Legionnaires' Bacteria Regrew in Bronx Cooling Towers That Were Disinfected->

schwit1 writes: The 15 water-cooling towers that were found to be contaminated this week amid a new cluster of Legionnaires' disease cases had been disinfected less than two months ago, New York City officials said on Thursday, raising questions about how successful the city can be in containing the disease.

After an outbreak of the disease killed 12 people in July and August in the South Bronx, the city required every building with cooling towers, a common source of the Legionella bacteria that cause the disease, to be cleaned within two weeks.

Despite that order, as well as new legislation mandating quarterly inspections of cooling towers, the city found this week that bacteria had regrown in at least 15 towers that had been cleaned recently in the Morris Park section of the Bronx. The testing occurred after a fresh outbreak in that area that has killed one person and sickened at least 12, and spurred an order from health officials for the towers to be disinfected again.

Submission The Decline of 'Big Soda': Is Drinking Soda the New Smoking? writes: Margot Sanger-Katz reports in the NYT that soda consumption is experiencing a serious and sustained decline as sales of full-calorie soda in the United States have plummeted by more than 25 percent over the past twenty years. Nearly two-thirds of Americans say they are actively trying to avoid the drinks that have been a mainstay of American culture but bottled water is now on track to overtake soda as the largest beverage category in two years. The changing patterns of soda drinking appear to come thanks, in part, to a loud campaign to eradicate sodas. School cafeterias and vending machines no longer contain regular sodas. Many workplaces and government offices have similarly prohibited their sale.

For many public health advocates, soda has become the new tobacco — a toxic product to be banned, taxed and stigmatized. “There will always be soda, but I think the era of it being acceptable for kids to drink soda all day long is passing, slowly,” says Marion Nestle. “In some socioeconomic groups, it’s over.” Soda represents nearly 25% of the U.S. beverage market and its massive scale have guaranteed profit margins for decades. Historically, beverage preferences are set in adolescence, the first time that most people begin choosing and buying a favorite brand. But the declines in soda drinking appear to be sharpest among young Americans. "Kids these days are growing up with all of these other options, and there are some parents who say, ‘I really want my kids to drink juice or a bottled water,’ ” says Gary A. Hemphill. “If kids grow up without carbonated soft drinks, the likelihood that they are going to grow up and, when they are 35, start drinking is very low.”

Submission Weekend at Zuckerberg's: Soon-to-Be US Ed Chief Was Almost FB CEO's Ed Chief

theodp writes: Before President Obama announced John B. King as his pick to replace outgoing U.S. Education Secretary Arne Duncan (who is returning to Chicago, where his kids now attend a $30K-a-year private school), King was Facebook CEO Mark Zuckerberg's pick to lead Zuck's failed $100 million "reform" effort of Newark's Schools. From The Prize: Who’s in Charge of America’s Schools?: "[Newark Mayor Cory] Booker asked [NJ Governor Chris] Christie to grant him control of the schools by fiat, but the governor demurred, offering him instead a role as unofficial partner in all decisions and policies, beginning with their joint selection of a 'superstar' superintendent to lead the charge. Booker’s first choice was John King, then deputy New York State education commissioner, who had led some of the top-performing charter schools in New York City and Boston and who credited public school teachers with inspiring him to persevere after he was orphaned as a young boy in Brooklyn. [Mark] Zuckerberg and [his wife Priscilla] Chan flew King to Palo Alto for a weekend with them and [Facebook executive Sheryl] Sandberg; Christie hosted him at the governor’s beach retreat on the Jersey Shore; and Booker led King and his wife, Melissa, on a tour of Newark, with stops at parks and businesses that hadn’t existed before his mayoralty. But after much thought, King turned them down. Zuckerberg, Christie, and Booker expected to arrive at their national model within five years. King believed it could take almost that long to change the system’s fundamental procedures and to raise expectations across the city for children and schools. “John’s view was that no one has achieved what they’re trying to achieve: build an urban school district serving high-poverty kids that gets uniformly strong outcomes,” said an acquaintance who talked with King about the offer. “You’d have to invest not only a long period of time but tremendous political capital to get it done.” King had questions about a five-year plan overseen by politicians who were likely to seek higher office."

MarkWhittington writes: A little while ago, SpaceX CEO Elon Musk got into trouble when he proposed, as a quick way to terraform Mars, exploding nuclear bombs on the Red Planet’s poles. The idea was that the bombs would heat up the frozen carbon dioxide at the poles, covering Mars with greenhouse gasses that would in due course heat up the planet. Of course, the scheme would also render Mars uninhabitable by spreading radioactive fallout. According to Mashable, Musk clarified his scheme.

Researchers at Columbia University's Lamont-Doherty Earth Observatory dated the tsunami at 73,000 years ago.
Its interesting that this is about the same time as the Mt. Toba Eruption and about the same time humans nearly became extinct.

Submission Artists create a 1000 year GIF loop

jovius writes: Finnish artists Juha van Ingen and Janne Särkelä have developed a monumental GIF called AS Long As Possible, which loops once per 1000 years. The 12 gigabyte GIF is made of 48,140,288 numbered frames, that change about every 10 minutes. They plan to start the loop in 2017, when GIF turns 30 years old. "If nurturing a GIF loop even for 100 — let alone 3,000 years — seems an unbelievable task, how much remains of our present digital culture after that time?”, van Ingen said. The artists plan to store a mother file somewhere and create many iterations of the loop in various locations — and if one fails, it may be easily synchronized with, and replaced by, another.

England on edge as old foes threaten to spoil the party:
Stuart Lancaster's men must shoulder the hopes of a nation, and beyond, in their win-or-bust game against Australia at Twickenham on Saturday. LONDON, 3 Oct — There are still four weeks to the final of Rugby World Cup 2015 on Halloween but the real night of horror for English rugby will unfold a month early if they cannot repel the challenge of Australia in front of what could be the most fevered Twickenham crowd the old stadium has ever housed. These nations have met in two World Cup finals, winning one apiece in each other’s backyard, and so even if we cannot call this the biggest match they have ever contested in their 106-year rivalry, England coach Stuart Lancaster reckons this pool match has the feel of another RWC final. No wonder. Because for him and for a nation that has poured so much expense and effort into making this the finest World Cup of all, the prospect of England becoming the first hosts to be eliminated in the pool stages is one that really does not bear thinking about. It is simple. England lose and they are out, leaving only a long, painful inquest and the Rugby Football Union to reflect on a once-in-a-generation opportunity missed. Never mind the deflating sense of national anticlimax; the London Business School is reported as saying an England loss would cost Britain’s leading companies £3 billion.
The £3 billion game. Er, so, no pressure on Lancaster’s troops then. If they were to think too much about that, it would suffocate them from the kick-off. “But I have to make sure the players are not focusing on the size of the game,” Lancaster says. In what will be the test of their sporting lives, to avoid the doomsday scenario they will have to be clear-headed, disciplined and clinical, all the attributes that eventually failed them against Wales last weekend, and perform with the same defiance and passion they have been talking about all week. Ben Youngs, England’s sparky scrum-half, insisted they had to give the Australians “a reason to fold” by coming out in the first 20 minutes with an intensity of purpose and clarity of execution that would blow the Wallabies away. “The fact of the matter is Australia have potentially got a reason to quit. They can play Wales (next Saturday) and get a result. They can afford to lose a game.” Yet that sounds like wishful thinking. Australia cannot really afford to lose this game either, leaving everything up in the air for a third successive Saturday of Twickenham high drama. Sounding confident and settled, they have bought into inspirational coach Michael Cheika’s philosophy that they should play every game in that green and gold "as if it is going to be their last".
England are counting on the sort of emphatic set-piece domination they enjoyed, not for the first time over the Wallabies in recent years, during last November's international victory at Twickenham but Cheika fancies his scrum will be a different proposition now under the guidance of former Argentina hooker Mario Ledesma. Any form of parity there and the Wallabies, having already demonstrated their driving maul capabilities against Fiji, will also believe they have a more potent and settled back line than the home side, even if Jonathan Joseph’s return after a chest injury is seen as key to England offering any attacking invention of their own. England will trust in Owen Farrell to win any kicking duel should another close affair ensue. They have won the past three World Cup encounters by three points or less but breakdown scavengers Michael Hooper and David Pocock look potential Wallaby matchwinners. Indeed, Pocock began the tournament against Fiji with two tries, five turnovers and 14 tackles, offering the sort of tour de force that makes him look the best back-row operator in the business. Tickets are in such demand for this contest that they are reported to be selling for up to £4,000 each. Everyone wants to see this epic collision and England captain Chris Robshaw can feel the tsunami of support pushing his side on. “We want to go out and do everybody proud," he said. "Family, friends, and most of all the country.” England does not so much expect as demand.

Australia's Michael Cheika deflects England barbs with a laugh:
It is all about EQ not IQ, Wallabies coach warns hosts as he shrugs off Sir Clive Woodward's criticism on eve of crunch Pool A clash. LONDON, 2 Oct — On the eve of the match that could see England kicked out of their own rugby party, Australia were in the mood to laugh off any barbs from the hosts which might be designed to unsettle them at Twickenham. So coach Michael Cheika, asked to respond to Sir Clive Woodward’s comments in an English newspaper that his Wallabies team was “not the brightest”, grinned and agreed that, actually, his academic qualifications did leave a lot to be desired. Then, presented with news that England’s rejected fly-half Danny Cipriani had gone public with his observation that not a single Wallaby player would make the hosts’ first XV, the experienced Adam Ashley-Cooper could not resist the dig that the Sale maverick would not get in their side either. After a week of fairly tame fare in the war of words that routinely precede the biggest matches, Cheika (pictured above) could not help wearing a broad smile when told of the comment of England’s 2003 World Cup-winning coach Woodward that Stuart Lancaster’s side could profit from Australia’s propensity to lack intelligence in their approach.
“Mr Woodward’s right. I only got 300 out of 500 in my high school certificate. My mother wasn't happy with the results either, I can assure you. She begged me to study harder. Somehow I got through, I don’t know how. Fluked it, I suppose,” said the extraordinarily bright, self-made millionaire Cheika. Then he got a mite more serious. “Sometimes, it’s not intelligence but emotional intelligence that helps in this game. It’s not the IQ, it’s the EQ. So hopefully we’ve got a bit of EQ among us. We’re doing our best for our country. I understand it’s all a bit of fun and games, a bit of a snipe here and a snipe there, so I’m pretty comfortable with all that stuff.”The coach has played a low-key, diplomatic blinder all week, giving the hosts no ammunition to sling about, and Ashley-Cooper, who is set for his ninth encounter with England, has had a fair bit of experience at these mind games too. So when he heard of the extraordinary blog of Cipriani, who just missed out on England’s final 31-man squad, on a bookmaker’s website, it was evidently manna to him.
“Not one Australian would get into that England team right now,” Cipriani wrote, and you could almost imagine Lancaster tearing his own hair out at one of his players having effectively written the Wallabies’ team talk for them. “The Aussies will be fired up, but when it comes down to it, head-to-head England are too strong.” To which, Ashley-Cooper just shrugged: “It’s just nice that he’s tweeting about something else other than himself. Danny’s a good bloke, I enjoy his selfies a lot but he can say what he likes. He wouldn’t be a part of our team either (laughs).” All good knockabout stuff and with the stakes so high before the game of the tournament so far, Cheika did not mind in the slightest the opportunity for a bit of light relief. Hence, the heavy metal AC/DC hit Thunderstruck blaring out at Twickenham during their captain’s run on Friday. “One of the coaches, Stephen Larkham, who’s a slightly random type of fellow, just decided to turn it on at training one day earlier this week,” Cheika explained.
“I didn’t know much about it, I had to ask him about the song, it wouldn’t always be my style of music. But I’ve come to love that song now. It’s just a bit of fun, gets the players having a bit of a laugh and we want to enjoy our time playing the game.” Cheika, renowned as a great ‘sledger’ on the field, reckoned it was not a deliberate policy not to get involved with pointless slanging matches. “It's just my nature. I know it's all a bit of fun that stuff but anyone who has played the game at this level will tell you it is pretty irrelevant. “I believe a lot in my own players. Having a crack at other players, it's all a bit of show, I don't think that's what I am here to be doing. Others can do that." The only thing that was important to him, he reckoned, was getting his men into a frame of mind where they “are giving everything so our nation can be proud of us".

Submission The physics behind the Volkswagen diesel scandal ->

Guinnessy writes: Volkswagen recently admitted that it equipped diesel cars with "defeat devices" that belch 40 times the EPA standard on nitrogen oxides. Yet despite the mass of coverage, details on exactly how the devices cheated on emissions tests, and why diesels expel such gases have been sketchy. Physics Today's Charles Day takes a look ( ) at how diesel engines work, and why its clear its not just a lone software engineer who came up with the cheat. " is impotent without hardware. To recognize when a car was being tested and not driven, the defeat device required data from a range of sensors—sensors that a noncheating car might not need.... Whereas it's conceivable that a single software engineer, directed by a single manager, could have secretly written and uploaded the code that ran the defeat device, installing its associated hardware would require a larger and more diverse team of conspirators," he says.

Submission DARPA is looking for Analog Approaches To Cyber Monitoring ->

chicksdaddy writes: Frustrated by adversaries continued success at circumventing or defeating cyber defense and monitoring technologies, DARPA is looking to fund new approaches, including the monitoring of analog emissions from connected devices, including embedded systems, industrial control systems and Internet of Things endpoints, Security Ledger reports (

DARPA is putting $36m to fund the Leveraging the Analog Domain for Security (LADS) Program. ( — PDF) The agency is looking for proposals for “enhanced cyber defense through analysis of involuntary analog emissions,” including things like “electromagnetic emissions, acoustic emanations, power fluctuations and thermal output variations.”

At the root of the program is frustration and a lack of confidence in digital monitoring and protection technologies developed for general purpose computing devices like desktops, laptops and servers. The information security community’s focus on “defense in-depth” approaches to cyber defense are ill suited for embedded systems because of cost, complexity or resource limitations. Even if that were possible, DARPA notes that “attackers have repeatedly demonstrated the ability to pierce protection boundaries, exploiting the fact that any security logic ultimately executes within the same computing unit as the rest of the (compromised) device software and the attacker’s code.”
