Clive Phillips and Matti Wilks report via ScienceAlert: In a recent survey, published this month in PLOS One, we investigated the views of people in the United States, a country with one of the largest appetites for meat and an equally large appetite for adopting new technologies. A total of 673 people responded to the survey, done online via Amazon Mechanical Turk, in which they were given information about in vitro meat (IVM) and asked questions about their attitudes to it. Although most people (65 percent), and particularly males, were willing to try IVM, only about a third said they would use it regularly or as a replacement for farmed meat. But many people were undecided: 26 percent were unsure if they would use it as a replacement for farmed meat and 31 percent unsure if they would eat it regularly. This suggests there is scope to persuade consumers that they should convert to IVM if a suitable product is available. As an indication of this potential, 53 percent said it was seen as preferable to soy substitutes. The biggest concerns were about IVM's taste and lack of appeal, particularly in the case of meats seen as healthy, such as fish and chicken, where only two-thirds of people that normally ate them said that they would if it was produced by in vitro methods. By contrast, 72 percent of people who normally eat beef and pig products would still do so if they were produced as IVM.

An anonymous reader shares an article on Quartz: Economist Robert Gordon has spent his career studying what makes the US labor force one of the world's most productive. And he has some bad news. American workers still produce some of most economic activity per hour of any economy in the world. But the near-miraculous productivity growth that essentially transformed the US into one of the world's most affluent societies is permanently in the country's rearview mirror. In his new book, The Rise and Fall of American Growth, the Northwestern University professor lays out the case that the productivity miracle underlying the American way of life was largely a one-time deal. It was driven by a flurry of technologies -- electric lights, telephones, automobiles, indoor plumbing -- that fundamentally transformed millions of American lives within a matter of decades. By comparison, Gordon argues, today's technological advancements -- Uber, Facebook, Amazon.com -- will touch the productivity of the American economy lightly -- if at all. And a combination of demographic factors, such as the aging of the US population, and sociological problems such as growing inequality and educational performance that's worsened in comparison to many other rich nations, will stymie economic growth for the foreseeable future.For those not following Gordon's work, he has been expressing these views for quite some time now. Here's his TED talk from 2013 It shouldn't come as a surprise that many strongly disagree with Gordon's views. Kevin Kelly wrote in 2013: I think Robert Gordon is wrong about his conclusion: According to Gordon growth has stalled in the internet age. This question was first asked by Robert Solow in 1987 and Gordon's answer is that there are 6 'headwinds' six negative, or contrary forces which deduct growth from the growth due to technology in the US (Gordon reiterates he is only speaking of the US). The six 'headwinds' slowing down growth are the aging of the US population, stagnant levels of education, rising inequality, outsourcing and globalization, environmental constraints, and household and government debt. I agree with Gordon about these headwinds, particularly the first one, which he also sees as the most important. Where Gordon is wrong is his misunderstanding and underestimating of the power of technological growth before it meets these headwinds. First, as mentioned above, he underestimates the value of the innovations that the internet has brought us. They seem trivial compared to running water and electric lights, but in fact, as billions around the world show us, they are just as valuable. [...] So the 3rd Industrial Revolution is not really computers and the internet, it is the networking of everything. And in that regime we are just at the beginning of the beginning. We have only begun to connect everything to everything and to make little network minds everywhere. It may take another 80 years for the full effect of this revolution to be revealed. In the year 2095 when economic grad students are asked to review this paper of Robert Gordon and write about why he was wrong back in 2012, they will say things like "Gordon missed the impact from the real inventions of this revolution: big data, ubiquitous mobile, quantified self, cheap AI, and personal work robots. All of these were far more consequential than stand alone computation, and yet all of them were embryonic and visible when he wrote his paper. He was looking backwards instead of forward." You might also find Freakonomics' Stephen J. Dubner views on this interesting.

An anonymous reader writes: A report issued by the UK's Organization for Economic Cooperation and Development has evaluated how technology in classrooms affects test results, and found that the availability of computers provides "no noticeable improvement" to students' test scores. According to the report, "Students who use computers very frequently at school get worse results." Also, "high achieving school systems such as South Korea and Shanghai in China have lower levels of computer use in school." The organization warns that classroom technology can be a distraction if implemented unwisely, and it also opens the door to easy ways of cheating.

jones_supa writes "The latest PISA (Programme for International Assessment) results are out today. Since 2000, the OECD has attempted to evaluate the knowledge and skills of 15-year olds across the world through its PISA test. More than 510,000 students in 65 economies took part in the latest test, which covered math, reading and science, with the main focus on math — which the OECD state is a 'strong predictor of participation in post-secondary education and future success.' Asian countries outperform the rest of the world, according to the OECD, with Shanghai, Singapore, Hong Kong, Taiwan, South Korea, Macau and Japan amongst the top performing countries and economies. Students in Shanghai performed so well in math that the OECD report compares their scoring to the equivalent of nearly three years of schooling above most OECD countries. The study shows also a slight gender cap: in all countries, boys generally perform a bit better than girls, but this applies only to math." Here's a spreadsheet listing each country's results. The U.S. ranked 26th in math (below average), 17th in reading (slightly above average), and 21st in science (slightly below average).

New submitter Norwell Bob sends this excerpt from an Associated Press report: "It's long been known that America's school kids haven't measured well compared with international peers. Now, there's a new twist: Adults don't either. In math, reading and problem-solving using technology – all skills considered critical for global competitiveness and economic strength – American adults scored below the international average on a global test, according to results (PDF) released Tuesday."

Albanach writes "An OECD report published today has shown moderate cell phone users in the United States are paying some of the highest rates in the world . Average US plans cost $52.99 per month compared to an average of $10.95 in Finland. The full report is available only to subscribers, however Excel sheets of the raw data are available to download." (You'll find those Excel sheets — which open just fine in OpenOffice — on the summary page linked above.)

Xemu writes "French scientists have linked obesity to lower IQ reports the Telegraph. In a new five-year study of more than 2,200 adults, people with a low body mass index (BMI) could recall 30% more words in a vocabulary test than those who were obese. The fatter subjects also showed a higher rate of cognitive decline when they were retested five years later. In the United States, 30% of the population is obese according to OECD. That's the highest rate of obesity anywhere. Do these high obesity rates affect the average IQ of the population?" (Of course, this sidesteps discussion of whether IQ tests measure anything significant at all.)

3l1za writes "The New York Times reports that the Organization for Economic Cooperation and Development has released its results (pdf) for a test of mathematical skills given to 15 year olds in 40 different countries. A few apparent anomalies: The US kids rated 28th of 40 (so in the bottom third) while the Czech Republic, which spends in education 1/3 of what the US spends, ranked in the top 10. Further, only about 1/3 of US kids reported that they did not feel as though they were good at math, whereas about 2/3 of Koreans reported this--and the Koreans ranked in the top three. 'Mr. Schleicher said that students in countries that emphasized theorems and rote learning tended not to do as well as those that emphasized the more practical aspects of mathematics.'"

Trigun writes "The Seattle Post-Intelligencer is reporting that movie and software downloads have outpaced music downloads. Music accounted for 48.6 percent of files shared online, compared with 62.5 percent in 2002, according to a report by the Organization for Economic Cooperation and Development. The article says that 1 in 4 internet users have downloaded at least one movie, and attributes the proliferation to access to broadband. Maybe we've just downloaded all the good music already?"

Lets start this off with some eyecandy from Mdog. Hi res pics of coronal loops meet Rob's First Rule of Art. Wow. Not enough eye candy? tradica noted that Pixar's new movie 'Monsters Inc.' now has trailers available even the the movie won't be out for a year. Course since Jobs is @ pixar, no surprise that I can't watch the clip. Instead of food for your retinas, Nerf97A4 sent in recipes that will never be used on Iron Chef since they all involve cooking with twinkies in some form or another. Deep fried Twinkies? Makes me shudder... maybe instead you should look at jedigeek fouund an online store called CyberCandy which allows you to buy candy from around the world. funferal noticed that a OECD have publshed their Privacy Statement Generator. Ant noted one wizard that that probably doesn't exist in Word. alecto sent us a fun link where you can read 99 Bottles of Beer on the Wall which has code snippets to generate the song in languages from APL to zsh. PhadeRunner sent us Mr. T vs. The Matrix. and FlameSnyper sent The Matrix and Ghost in The Shell. One is slightly more serious then the other. An anonymous reader documented filling a cubicle with packing peanuts in case your boss is out of time and you need some help. Speaking of bosses, Need a weapon? WD_40 aims you at a site where you can learn how to create your own spud gun. Course you could do it the old fashioned way: pimp showed us a site dedicated to electrocuting common household stuff. Like, for example, a furby. While on the subject of electricity, loose_change sent in several links about Power meters and how they aren't exactly the best in user interface. A competition followed to try to make a better on. The winner is definitely less hostile ;) CresentCityRon sent in something you don't want to electrocute: apparently MIT students are working on Geek Porn which is pretty much what is sounds like. School officials aren't so happy about it.
