sosaited writes "It has been widely believed that our ancestors originated out of Africa, but a paper published in Nature by Carnegie Museum of Natural History scientists puts this in doubt. The paper is based on the fossils of four primate species found in Asia which are 40 million years old, during which period Africa was thought to not have these species. The diversity and timing of the new anthropoids raises two scenarios. Anthropoids might simply have emerged in Africa much earlier than thought, and gone undiscovered by modern paleontologists. Or they could have crossed over from Asia, where evidence suggests that anthropoids lived 55 million years ago, flourishing and diversifying in the wide-open ecological niches of an anthropoid-free Africa."

An anonymous reader writes "Be careful mentioning Dr. Ann De Wees Allen. She's made it clear that she's trademarked her name and using it is 'illegal... without prior written permission.' She even lists out the names of offenders and shows you the cease-and-desist letter she sends them. And, especially don't copy any of the text on her website, because she's using a bit of javascript that will warn you 'Copyright Protect!' if you right click on a link."

thecarchik writes "America loves to complain about gas mileage and the cost of gasoline. As it turns out, part of the problem is us. How much does it really matter? A study by the Centers for Disease Control and Prevention found a 1.1 percent increase in self-reported obesity, which translates into extra weight that your vehicle has to haul around. The study estimates that 1 billion extra gallons of fuel were needed to compensate for passenger weight gained between 1960 and 2002."

Antidepressants may help a lot of people get up in the morning but new research shows they are making shrimp swim into that big bowl of cocktail sauce in the sky. Alex Ford, a marine biologist at the University of Portsmouth, found that shrimp exposed to the antidepressant fluoxetine are 5 times more likely to swim towards light instead of away from it. Shrimp usually swim away from light as it is associated with birds or fishermen.

theodp writes "A third-grader in a small Texas school district received a week's detention for merely possessing a Jolly Rancher. Leighann Adair, 10, was eating lunch Monday when a teacher confiscated the candy. Her parents said she was in tears when she arrived home later that afternoon and handed them the detention notice. But school officials are defending the sentence, saying the school was abiding by a state guideline that banned 'minimal nutrition' foods. 'Whether or not I agree with the guidelines, we have to follow the rules,' said school superintendent Jack Ellis."

Gud writes "According to The Washington Post a 9-year-old was able to hack into his county's school computer network and change such things as passwords, course work, and enrollment info. From the article: 'Police say a 9-year-old McLean boy hacked into the Blackboard Learning System used by the county school system to change teachers' and staff members' passwords, change or delete course content, and change course enrollment. One of the victims was Fairfax Superintendent Jack D. Dale, according to an affidavit filed by a Fairfax detective in Fairfax Circuit Court this week. But police and school officials decided no harm, no foul. The boy did not intend to do any serious damage, and didn't, so the police withdrew and are allowing the school district to handle the half-grown hacker.'"

thomst writes "Charles Q. Choi of LiveScience reports that a farmer in southern Henan Province in China has dug up the first known ant-eating dinosaur, a half-meter-long theropod (the dinosaur family to which T. Rex belongs), whose fossilized remains were described as 'fairly intact'. The 83- to 89-million-year-old pygmy dinosaur has been named named Xixianykus zhangi by Xig Xu, De-you Wang, Corwin Sullivan, David Hone, Feng-lu Han, Rong-hao Yan, and Fu-ming Du, whose paper on the critter, A basal parvicursorine (Theropoda: Alvarezsauridae) from the Upper Cretaceous of China, was published in the March 29 issue of Zootaxa (the abstract is available in PDF format for free, the full article is paywall-protected.)"

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

The Guardian's Games blog explores the tendency of modern video games to suffer from poor voice acting, a flaw made all the more glaring by increasingly precise and impressive graphics. Quoting: "Due to the interactive nature of games, actors can't be given a standard film script from which they're able to gauge the throughline of their character and a feel for the dramatic development of the narrative. Instead, lines of dialogue need to be isolated into chunks so they can be accessed and triggered within the game in line with the actions of each individual player. Consequently, the performer will usually be presented with a spreadsheet jammed with hundreds of single lines of dialogue, with little sense of context or interaction. ... But according to David Sobolov, one of the most experienced videogame voice actors in the world (just check out his website), the significant time pressures mean that close, in-depth direction is not always possible. 'Often, there's a need to record a great number of lines, so to keep the session moving, once we've established the tone of the character we're performing, the director will silently direct us using the spreadsheet on the screen by simply moving the cursor down the page to indicate if he/she liked what we did. Or they'll make up a code, like typing an 'x' to ask us to give them another take.' It sounds, in effect, like a sort of acting battery farm, a grinding, dehumanizing production line of disembodied phrases, delivered for hours on end. Hardly conducive to Oscar-winning performances."

ral writes "The human tongue can taste more than sweet, sour, salty, bitter and protein. Researchers have added fat to that list. Dr. Russell Keast, an exercise and nutrition sciences professor at Deakin University in Melbourne, told Slashfood, 'This makes logical sense. We have sweet to identify carbohydrate/sugars, and umami to identify protein/amino acids, so we could expect a taste to identify the other macronutrient: fat.' In the Deakin study, which appears in the latest issue of the British Journal of Nutrition, Dr. Keast and his team gave a group of 33 people fatty acids found in common foods, mixed in with nonfat milk to disguise the telltale fat texture. All 33 could detect the fatty acids to at least a small degree."

DeviceGuru writes "LinuxDevices reports that a group of companies today unveiled — and demonstrated products based on — a tiny new PCI Express expansion standard. Although it's somewhat larger than the PCI Express Mini Card, the tiny new 43mm x 65mm FeaturePak card's high density 230-pin edgecard connector provides twice the number of PCI Express and USB 2.0 channels to the host computer, plus 100 lines dedicated to general purpose I/O, of which 34 signal pairs are implemented with enhanced isolation for use in applications such as gigabit Ethernet or high-precision analog I/O. While FeaturePaks will certainly be used in all sorts of embedded devices (medical instruments, test equipment, etc.), the tiny cards could also be used for developing configurable consumer devices, for example to add an embedded firewall/router or security processor to laptop or notebook computers, or for modular functionality in TV set-top-boxes and Internet edge devices." The president of Diamond Systems, which invented the new card, said "Following the FeaturePak initiative's initial launch, we intend to turn the FeaturePak specification, trademark, and logo over to a suitable standards organization so it can become an industry-wide, open-architecture, embedded standard" (but to use the logo you have to join the organization).

medea and several other readers noted that the LHC came back online early this morning. Here is the tweet from CERN announcing the milestone. As we discussed a few weeks ago, CERN plans to run the LHC at half power or less through 2011.

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.
