Evolution's Path May Lead To Shorter, Heavier Women 411

Hugh Pickens writes "Yale University researchers believe that if evolutionary pressures of sexual selection and reproductive fitness continue for another 10 generations, the trends detected in their study may mean that the average woman in 2409 AD will be 2 cm shorter, 1 kg heavier, will bear her first child five months earlier, and enter menopause 10 months later. 'There is this idea that because medicine has been so good at reducing mortality rates, that means that natural selection is no longer operating in humans,' says Stephen Stearns of Yale University. 'That's just plain false.' Stearns and his team studied the medical histories of 14,000 residents of the Massachusetts town of Framingham, using medical data from a study going back to 1948 spanning three generations, and found that shorter, heavier women had more children than lighter, taller ones. Women with lower blood pressure and cholesterol were also more likely to have large families as were women who gave birth early or had a late menopause. More importantly, these traits are then passed on to their daughters, who also, on average, had more children. The study has not determined why these factors are linked to reproductive success, but it is likely that they indicate genetic, rather than environmental, effects. 'The evolution that's going on in the Framingham women is like average rates of evolution measured in other plants and animals,' says Stearns. 'These results place humans in the medium-to-slow end of the range of rates observed for other living things.'"

The Myth of the Mathematics Gender Gap 588

Coryoth writes "The widely held belief that there is disparity in the innate mathematical abilities of men and women has been steadily whittled down in recent years. The gender gap in basic mathematics skills closed some time ago, and recently the gap in high school mathematics has closed up as well, with as many girls as boys now taking high school calculus. Newsweek reports on a new study published in The Proceedings of the National Academy of Sciences that begins to lay to rest the remaining argument that it is at the highest levels of mathematics that the innate differences show. Certainly men dominate current academia, with 70% of mathematics Ph.D.s going to men; however that figure is down from 95% in the 1950s. Indeed, while there remain gaps in achievement between the genders, the study shows that not only are these gaps closing, but the size of the gap varies over differing cultures and correlates with the general degree of gender inequality in the culture (as defined by World Economic Forum measures). In all, this amounts to strong evidence that the differences in outcomes in mathematics between the genders is driven by sociocultural factors rather than innate differences in ability."

Australian Censorship Bypassed Before Live Trials 184

newt writes "The Australian Government is planning to conduct live trials of as-yet-unspecified censorship technology. But as every geek already knows, these systems can't possibly work in the presence of VPNs and proxy servers. PC Authority clues the punters in." Maybe the ISPs secretly like encouraging SSH tunneling — and making everyone pay for the extra bandwidth used. Not really; Australia's major ISPs, as mentioned a few days ago, think it's a bad idea.

Casting Doubt On the Hawkeye Ball-Calling System 220

Human judgment by referees is increasingly being supplemented (and sometimes overridden) by computerized observation systems. nuke-alwin writes "It is obvious that any model is only as accurate as the data in it, and technologies such as Hawkeye can never remove all doubt about the position of a ball. Wimbledon appears to accept the Hawkeye prediction as absolute, but researchers at Cardiff University will soon publish a paper disputing the accuracy of the system."

Diebold Voter Fraud Rumors in New Hampshire Primaries 861

Westech writes "Multiple indications of vote fraud are beginning to pop up regarding the New Hampshire primary elections. Roughly 80% of New Hampshire precincts use Diebold machines, while the remaining 20% are hand counted. A Black Box Voting contributor has compiled a chart of results from hand counted precincts vs. results from machine counted precincts. In machine counted precincts, Clinton beat Obama by almost 5%. In hand counted precincts, Obama beat Clinton by over 4%, which closely matches the scientific polls that were conducted leading up to the election. Another issue is the Republican results from Sutton precinct. The final results showed Ron Paul with 0 votes in Sutton. The next day a Ron Paul supporter came forward claiming that both she and several of her family members had voted for Ron Paul in Sutton. Black Box Voting reports that after being asked about the discrepancy Sutton officials decided that Ron Paul actually received 31 votes in Sutton, but they were left off of the tally sheet due to 'human error.'"

Submission + - Where are all the hdtv tuners?

An anonymous reader writes: Today I read about rabbit ears making a comeback with OTA HTDV. I want to purchase a standalone ATSC HDTV tuner to go with my projector, but I am having a very hard time finding one. The big-box stores seem to only stock one or two models and are frequently sold out. Searching online yields similar results. It would seem that there would be ever increasing demand for these tuners given that many HDTVs were sold without internal tuners in years past and these tuners will be necessary for all old NTSC TVs after the February, 2009 shutdown of analog broadcasts. Where should I look to buy one of these devices? Of the currently available models, which are the best? Will the standalone HDTV tuner become a ubiquitous item as the 2009 deadline approaches?

NMR Shows That Nuclear Storage Degrades 385

eldavojohn writes to point out recent research using nuclear magnetic resonance (NMR) imagery that shows that certain nuclear waste storage containers may not be as safe as previously thought. From the article: "[R]adiation emitted from [plutonium] waste could transform one candidate storage material into less durable glass after just 1,400 years — much more quickly than thought... The problem is that the radioactive waste damages the matrix that contains it. Many of the waste substances, including plutonium-239, emit alpha radiation, which travels for only very short distances (barely a few hundredths of a millimeter) in the ceramic, but creates havoc along the way."
