While growth prospects in the field are incredibly high, recent trends, such as "tools grow[ing] more advanced" (see Adobe Flash Builder or MS Visual Studio) have had people wondering over the past few years if computer science has much room for growth left. Some question whether it is alive. Others, such as Carnegie Mellon, say not so fast. In any case, employment has been a bit iffy (/.). There is the possibility that Computer Science is simply growing up (PDF), then again the U of Florida decided to say good bye to it this past week. But hey, if you are not going to that University, and still are shooting for computer science, here are some tips.

MIT is leading an NSF-funded project with researchers from University of Pennsylvania and Harvard that aims to enable anyone to "design, customize and print a specialized robot in a matter of hours." Constructed from "cyber-physical primitives," the robots (some early examples here) would be able to be made in bulk on demand and could help change the entire workflow of device and robot creation, from engineering to warehousing to assembly.

Amazon has recently declared that tomorrow is Price Check day. If you go into a brick and mortar retail store with Amazon’s new Price Check App on your smart phone, and scan a barcode with the location settings active, and then report back to Amazon on the price of that product, Amazon will deduct $5 from your online purchase of that product. Amazon claims it’s trying to keep prices low for consumers, but others attribute the move to a less innocuous agenda. [more inside]

Obese monkeys lose weight by new drug that kills off fat cells. Adipotide is the newest weapon in the war on obesity. Unlike other weight-loss drugs that try to suppress appetite, boost one's metabolism, or block the absorption of fat, Adipotide blocks the blood supply that feeds fatty tissue. Studies show monkeys lost 11% of their body weight after 4 weeks of treatment.

The Triumph of New-Age Medicine "Medicine has long decried acupuncture, homeopathy, and the like as dangerous nonsense that preys on the gullible. Again and again, carefully controlled studies have shown alternative medicine to work no better than a placebo. But now many doctors admit that alternative medicine often seems to do a better job of making patients well, and at a much lower cost, than mainstream care—and they’re trying to learn from it."

"Over the past few decades, 160 million women have vanished from East and South Asia — or, to be more accurate, they were never born at all. Throughout the region, the practice of sex selection — prenatal sex screening followed by selective termination of pregnancies — has yielded a generation packed with boys. From a normal level of 105 boys to 100 girls, the ratio has shifted to 120, 150, and, in some cases, nearly 200 boys born for every 100 girls. In some countries, like South Korea, ratios spiked and are now returning to normal. But sex selection is on the rise in Eastern Europe, Southeast Asia, and the Middle East." American journalist Mara Hvistendahl's new book: "Unnatural Selection: Choosing Boys Over Girls, and the Consequences of a World Full of Men," examines and tries to predict the actual and potential effects of unequal sex ratios on men, women and the social economies of the affected regions, including the recent spike in sex trafficking and bride-buying across Asia.

"The New York Public Library’s Beaux-Arts Stephen A. Schwarzman Building celebrates its 100th anniversary this month on May 23. The Centennial offers a wonderful opportunity to reflect on Library use from the past 100 and uncover stories that can serve as inspiration for another century. One unique way to trace the history of the Library is through call slips. In order to use books in the research collection, patrons request specific titles by filling out a call slip, which includes the following information: author, title, and call number. Not all call slips have been saved over the years, but some have been preserved for posterity." Featured are slips from Max Eastman, Lewis Mumford, Dorothy Parker, John Dos Passos and R. G. Wasson...
Statistical hypothesis testing with a p-value of less than 0.05 is often used as a gold standard in science, and is required by peer reviewers and journals when stating results. Some statisticians argue that this indicates a cult of significance testing using a frequentist statistical framework that is counterintuitive and misunderstood by many scientists. Biostatisticians have argued that the (over)use of p-vaues come from "the mistaken idea that a single number can capture both the long-run outcomes of an experiment and the evidential meaning of a single result" and identify several other problems with significance testing. XKCD demonstrates how misunderstandings of the nature of the p-value, failure to adjust for multiple comparisons, and the file drawer problem result in likely spurious conclusions being published in the scientific literature and then being distorted further in the popular press. You can simulate a similar situation yourself. John Ioannidis uses problems with significance testing and other statistical concerns to argue, controversially, that "most published research findings are false." Will the use of Bayes factors replace classical hypothesis testing and p-values? Will something else?
Recent research on children. (1) Brothers and sisters who argue a lot can improve their language, social skills and outcomes: Guardian article; paper on part of the research (pdf). (2) First findings from Understanding Society. Conclusions include: the unhappiness of children’s mothers with their partners affect children’s happiness, but this is not the case if children’s fathers are unhappy in their relationships; having older brothers or sisters doesn’t appear to affect children’s happiness, but having younger brothers or sisters is associated with less happiness; not living with both natural parents has a greater negative impact on a young person’s life satisfaction than their material situation. (3) A longitudinal study on people now in their forties has found that for these people reading is linked to career success, though not necessarily to better pay, whilst playing computer games and doing no other activities was associated with less likelihood of going to university. In particular, those who owned a ZX Spectrum or Commodore C64 were less likely to go to university. thinq interview with researcher. Guardian article. Telegraph article.
