Video games may improve eyesight.
Darkfrog submitted, created time 1 year 5 months (sciencenow.sciencemag.org)
I played a lot of video games as a youngling and my contact lenses barely fit under my eyelids, but according to this article in Science magazine, that may be because I preferred story-based games to first-person-shooters.
Games that require the player to detect enemies and react quickly seem to be linked with improved contrast sensitivity--the ability to discern objects in low lighting.
This study was performed in male gamers and non-gamers in their late teens and early twenties, so these boys would have started out on DOOM and Quake 
Special investigation: How my genome was hacked

INTIMATE secrets hidden in your DNA could be stolen without you even realizing. By taking a glass from which you have drunk, a "genome hacker" could obtain a comprehensive scan of your genome, revealing DNA variants that help determine your susceptibility to a wide range of diseases, from a common form of blindness to Alzheimer's disease.
Method for Detecting 23 Drugs and Medicines in Saliva Developed

A team of scientists from the Institute of Legal Medicine at the University of Santiago de Compostela (USC) has developed a technique for detecting the presence of twenty-three illicit drugs and medicines in saliva samples. The method, published in the journal Analytical and Bioanalytical Chemistry, is already being used by the DGT in Spain, as part of a European study on the frequency of alcohol and drug consumption amongst drivers
Evolution hits the debate table again for Texas educators
Darkfrog submitted, created time 1 year 7 months (www.nytimes.com)
Texas is considering making changes to the way evolution is taught in schools, adding lines in textbooks that would play up what skeptics see as weaknesses in Darwin's theories.
What I found interesting about this article is that it pointed out why Texas is so important in American education: Because it is the biggest buyer of textbooks in the country, many publishers attune themselves to Texas's needs so that they do not have to print multiple versions.
Tight times stir people's interest in drug-trial jobs

An unemployed Omaha man's temporary gig will give his budget a shot in the arm. And when it's over, Ryan Meeks will be very familiar with the needle. Later this month, Meeks intends to participate in a clinical study for an osteoporosis drug. He'll pocket about $2,000 for giving thirty-eight blood samples, among other things, while spending eight days and nights away from home.
An Artist Develops a New Image--With Aid of Bacteria

Nearly five years ago, molecular biologist Edward Marcotte recalls, a high school dropout walked into his office at the University of Texas (UT), Austin, to talk shop. Despite the visitor's unconventional background, which included a stint as a video game programmer, Marcotte says that Zack Booth Simpson "won me over instantaneously. He was so clearly intelligent." They ended up talking for hours on topics such as Marcotte's use of data mining to extract information about the protein networks that control cellular functions.
DSM-IV gets reexamined. Expect a DSM-V in a few years.
Darkfrog submitted, created time 1 year 8 months (www.nytimes.com)
Psychologists are revising the DSM-IV. The Diagnostic and Statistical Manual of Mental Disorders has been altered a few times since its first edition came out in 1952 (hence the "IV") to reflect better information and changing ideas about what makes a healthy mind. For example, earlier versions of the DSM listed homosexuality as a disease. The DSM-IV does not
In the brain, justice is served from many parts
sea-maid submitted, created time 1 year 8 months (www.sciencenews.org)
Making decisions about crime and punishment is, it turns out, as complicated as a legal brief. For the first time, scientists have peered into the brains of people who are deciding whether a crime deserves punishment and how severe the penalty should be.
Those decisions involve parts of the brain associated with rational thought, but emotion-processing regions weigh in too, a team of law and neuroscience researchers from Vanderbilt University in Nashville, Tenn., show in a new study in the Dec. 11 Neuron
Vatican toughens stance on embryo research
sea-maid submitted, created time 1 year 8 months (www.nature.com)
The Roman Catholic Church has reaffirmed its opposition to embryonic stem cell research in a document that updates its twenty-year-old position on biomedical research and reproductive medicine.
The most significant change is that the Church rejects the idea that scientists who work with tissues derived from stem cells or fetuses are blameless so long as they had no part in the creation of the cell line or tissue sample
Well that's one way to present your dissertation...
Darkfrog submitted, created time 1 year 9 months (sciencenow.sciencemag.org)
This isn't quite as serious as our usual DiscoveR8 fare, but it has potential implications for science education and public image. You guys have often heard me give Science magazine the dubious praise, "You would NEVER see this in Nature." Something else that I say all the time, though, is, "My feelings can only be expressed through dance."
Science magazine sent out a rather interesting call for not-exactly-papers. The challenge was "Tell us about your Ph.D. research ...through dance
Loulan Beauty upsets Chinese View of Colonization of Xinjiang
Darkfrog submitted, created time 1 year 9 months (www.nytimes.com)
In Xinjiang, a part of China that mainstream culture considers to be entirely Chinese, the discovery of over two hundred extremely well-preserved and marketly not Han Chinese mummies have called that assertion into question. Xinjiang borders Kazakh and Mongolia.
My take? Well DUH. Human beings migrate like crazy. Borders change. My ancestors moved from God-knows-where to Ireland, displacing the people who lived there earlier. Today we call their other descendants "Irish" and wouldn't think of calling them anything else
Genetic testing may not be the best way to study one's ancestry
Darkfrog submitted, created time 1 year 9 months (www.nature.com)
In recent years, companies providing personal genetic exams have sprung up like mushrooms. For a fee and a cheek swab, they can will identify the client's countries of ancestry, even to specific regions.
However, Charmaine Royal of the the Duke Institute for Genome Sciences has serious reservations:
"The general limitation, I'd say, of all of these tests, is that they can't pinpoint with 100% accuracy who your ancestors may or may not be. Some people are concerned that the biogeographical ancestry test reifies the notion of race
Computer game "Spore" has Darwin doing stupid creature befriending dance in his grave!
Darkfrog submitted, created time 1 year 9 months (www.sciencemag.org)
The makers of the computer game "Spore" promise a real evolutionary experience: Start out the game as a microbe just trying to survive and travel all the way through the history of evolution into a species capable of a modern, civilized society! Depending on the choices the player makes early on in the game, the later species can have a seemingly limitless range of fascinating, monstrous forms
Economics: In defense of Smith--it's not like he didn't warn us
Darkfrog submitted, created time 1 year 10 months (www.nature.com)
I really liked reading this article. Ostensibly, it's about how all the pro economists know that there are flaws in the traditional economic models, but no one talks about them to intro students or in the media. Even undergraduate economics students are taught the traditional models in their basic classes, but they graduate and go into financial professions without anyone ever mentioning the points at which these models fail to work.
The public is left to assume that the models are wrong and that the economists must have some spooky ulterior motive
Gene-testing startup's study responds to critics

Navigenics, a Silicon Valley gene-testing startup is sick of all the criticism. The service that Navigenics offers is called personal genetic testing. Their customers are given a genetic writeup that covers markers for diseases like multiple schlerosis, glaucoma, obesity, and some kinds of cancers. Neither the article nor the Navigenics website says whether these customers are people who already have a family history of these conditions and wish to learn whether they inherited the tendency or whether they are simply curious
