Submission + - '55 Science Paper Retracted to Thwart Creationists

i_like_spam writes: The New York Times has an interesting story about a paper published in 1955 by Homer Jacobson, a chemistry professor at Brooklyn College. The paper, entitled "Information, Reproduction and the Origin of Life", speculated on the chemical qualities of earth in the Hadean time, billions of years ago when the planet was beginning to cool down to the point where, as Dr. Jacobson put it, "one could imagine a few hardy compounds could survive." Nobody paid much attention to the paper at the time, but today it is winning Dr. Jacobson acclaim that he does not want — from creationists who cite it as proof that life could not have emerged on earth without divine intervention. So after 52 years, he has retracted it.

Submission + - Brain Differences In Democrats and Republicans

i_like_spam writes: Scientists from NYU and UCLA report in Nature Neuroscience that the brains of Democrats and Republicans process information differently. This new study finds that the differences are apparent even when the brain processes common information, not just political topics. From the study, liberals were more likely to be accurate and showed more brain activity in the region associated with analyzing conflicts. A researcher not affiliated with the study stated, liberals 'could be expected to more readily accept new social, scientific or religious ideas.' Moreover, 'the results could explain why President Bush demonstrated a single-minded commitment to the Iraq war and why some people perceived Sen. John F. Kerry ... as a flip-flopper.

Submission + - High School Students Forced To Declare A Major

i_like_spam writes: As reported in the NYTimes, high school freshmen at many high schools across the nation are now being forced to pick a major. Starting this Fall, 9th graders in Florida will have to choose to major from among a set of state-approved subjects, while some students in Mississippi will have to follow one of nine designated career paths. High school administrators hope that having students declare majors will lead to greater student interest in school until graduation. College administrators think otherwise: 'youngsters should instead concentrate on developing a broad range of critical thinking and communication skills,' says Debra Humphreys from the Association of American Colleges and Universities.

Submission + - New Theory Explains Periodic Mass Extinctions

i_like_spam writes: The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science news, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.

Submission + - Higher Tuition For An Engineering Degree

i_like_spam writes: The NYTimes is running a story about a new trend in tuition charges at public universities throughout the country. Differential pricing schemes are being implemented, whereby majors in engineering and business pay higher tuition rates than majors in arts and humanities. Last year, for instance, engineering majors at the University of Nebraska starting paying an extra $40 per credit hour. One argument in support of differential pricing is that professors in engineering are more expensive than in other fields. However, others argue that engineering students '... who are charged more for their major will stick to the courses in their field to feel that they are getting their money's worth.'

Submission + - Change Google Background Color To Save Energy?

i_like_spam writes: Recent commentary at Nature Climate Change describes an on-going debate about the energy savings associated with the background colors used by high-traffic websites such as Google and the NYTimes. A back of the envelope calculation has suggested energy savings of 750 Megawatt hours per year if Google switched their background from white to black. In response, a new version of Google called Blackle was created. However, other calculations by the Wall Street Journal suggest minimal energy savings. Who is right in this debate? Should web designers also consider potential energy savings when choosing colors for their sites?

Submission + - Attackers Gain Full Control of iPhone

i_like_spam writes: The NYTimes is running a story about an iPhone flaw that has been found and documented by researchers from Independent Security Evaluators. Attackers were able to gain full control of the iPhone either through WiFi or by visiting a website with malicious code. The exploit will be demostrated at BlackHat on Aug. 2nd at 4:45pm. Until then,

Details on the vulnerability, but not a step-by-step guide to hacking the phone, can be found at www.exploitingiphone.com, which the researchers said would be unveiled today.

Submission + - Bogus Company Obtains Nuclear License

i_like_spam writes: As reported in the NY Times, undercover investigators from the Government Accountability Office set up a bogus company and received a license to purchase dirty-bomb nuclear materials from the Nuclear Regulatory Commission. The GAO's investigation shows that the security measures put in place after 911 are not sufficient for protecting the American people. From the article:

Given that terrorists have expressed an interest in obtaining nuclear material, the Congress and the American people expect licensing programs for these materials to be secure," said Gregory D. Kutz, an investigator at the accountability office, in testimony prepared for the hearing.

Submission + - Motorists Sue Over 'Hot' Fuel 5

i_like_spam writes: Motorists in 13 states have filed lawsuits against big oil companies and gas retailers alleging unfair pricing practices related to fuel-pumping temperatures. From an industry standard developed in the 1920's, the price for a gallon of gasoline is based on the density of the fuel at a temperature of 60 degress F. A gallon of gas at higher temperatures is less dense, and therefore contains less energy. The lawsuits claim additional costs of 3 to 9 cents per gallon without temperature adjustments. The fuel industry claims that the costs of installing temerature-adjustment sensors on every pump would be prohibitively high. These sensors are already installed in Canada, however, where the colder temperatures favor consumers.
It's funny.  Laugh.

Submission + - Will Linux Win the Next Presidential Election?

i_like_spam writes: Douglas Karr has posted an interesting breakdown, complete with bar charts, of the operating systems and server software used by the websites for 23 declared and undeclared presidential candidates. The breakdown shows that there is nearly an equal split between Linux and Windows servers among the whole candidate pool. More interesting, all of the Democratic candidates except for Hillary favor Linux or FreeBSD. 69% of the Republican candidates, in contrast, prefer Windows. Is this preference for OSS or Microsoft a true reflection of differing political philosophies? And, more importantly, will Linux win the next election?

Submission + - Are keyboards dishwasher safe?

i_like_spam writes: Computer keyboards are a breeding ground for bacteria. Studies have shown that keyboards often contain more bacteria than toilet seats. Common cleaning methods, such as pressurized-air canisters and damp rags, help remove some of the dirt, but they also leave behind plenty of grime. National Public Radio describes a recent experiment by a reporter who used a dishwasher to clean her keyboard. Following the advice on Plastic Bugs, she placed her keyboard in the top rack, didn't use the heated dry cycle, and air dried the keyboard for a week afterwards. Her keyboard is now squeaky clean and functions perfectly. Has anyone else tried this or any other alternate keyboards cleaning methods? For those not willing to air dry for a week, dishwasher-safe keyboards are now available.
