jamie writes "The Campbell's monkey has a vocabulary with at least six types of basic call, but new research published in the PNAS claims that they combine them and string them together to communicate new meanings. (Login may be required on the NY Times site.) For example, the word for 'leopard' gets an '-oo' suffix to mean 'unseen predator.' But when that word is repeated after 'come over here,' the combination means 'Timber!' — a warning of falling trees. Scientists have known for some time that vervet monkeys have different warning calls for different predators — eagle, leopard, and snake — but unlike the Campbell's monkeys, vervets don't combine those calls to create new meanings, a key component of syntax. The researchers plan to play back recordings to the monkeys to test their theories for syntax errors."Read more of this storyat Slashdot.
kkleiner writes "You may remember Liam Hoekstra, the baby apparently born without the myostatin gene, and consequently sporting 40% more skeletal muscle than his peers. Using gene therapy, NCH scientists have been able to get follistatin (a myostatin blocker) to promote phenomenal muscle growth in macaque monkeys. NCH is now working with the FDA to perform the preliminary steps necessary for a human clinical trial. Is this the prelude to a super-strength gene therapy for all of us?"Read more of this storyat Slashdot.
Following our recent discussions about the growing evidence pointing to possible life on Mars, reader skywatcher2501 writes with news of a study that has ruled out one possible explanation for the levels of methane seen on that planet — that it might be replenished by disintegrating meteors entering the atmosphere. So two theories remain: either the gas is created as a by-product of reactions between volcanic rock and water, or it is a by-product of a lifeform's metabolism.Read more of this storyat Slashdot.
mmmscience writes "Researchers have found a new sensory system in the skin that is completely separate from the traditional nerve network that gives us the sense of touch. The new system, comprising sensory nerves found on blood vessels and sweat glands, is not nearly as potent, but does allow people to sense temperatures and textures. The research suggests that the system may play a role in chronic pain disorders such as migraines and fibromyalgia, conditions whose causes remain a mystery."Read more of this storyat Slashdot.
ColdWetDog writes "Wired is running a story on DARPA's effort to stave off battlefield casualties by turning injured soldiers into zombies by injecting them with a cocktail of one chemical or another (details to be announced). From the article, 'Dr. Fossum predicts that each soldier will carry a syringe into combat zones or remote areas, and medic teams will be equipped with several. A single injection will minimize metabolic needs, de-animating injured troops by shutting down brain and heart function. Once treatment can be carried out, they'll be "re-animated" and — hopefully — as good as new.' If it doesn't pan out we can at least get zombie bacon and spam."Read more of this storyat Slashdot.
RobGoldsmith writes to tell us that Virgin Galactic has unveiled their latest take on manned space travel for the immediate future: SpaceShipTwo. The craft comes complete with matching mothership, WhiteKnightTwo, and will be officially unveiled today in the Mojave Desert just after dark. "Subject to certain US regulatory requirements that will guide the unveiling, SS2 will be attached to her WK2 mothership which was last year unveiled and named EVE after Sir Richard Branson's mother. In the future, WK2 will carry SS2 to above 50,000 feet (16 kilometers) before the spaceship is dropped and fires her rocket motor to launch into space from that altitude. In honor of a long tradition of using the word Enterprise in the naming of Royal Navy, US Navy, NASA vehicles and even science fiction spacecraft, Governor Schwarzenegger of California and Governor Richardson of New Mexico will today christen SS2 with the name Virgin Space Ship (VSS) ENTERPRISE. This represents not only an acknowledgment to that name’s honorable past but also looks to the future of the role of private enterprise in the development of the exploration, industrialization and human habitation of space."Read more of this storyat Slashdot.

Science Daily is reporting that researchers from Yale have discovered "very large RNA structures within previously unstudied bacteria that appear crucial to basic biological functions such as helping viruses infect cells or allowing genes to 'jump' to different parts of the chromosome." Ronald Breaker, professor of Molecular, Cellular, and Developmental Biology at Yale, stated that this would be equivalent to protein scientists finding a whole new class of enzymes. "The Breaker laboratory has used the explosion of DNA sequence information and new computer programs to discover six of the top twelve largest bacterial RNAs just in the last several years. One of the newly discovered RNAs, called GOLLD, is the third largest and most complex RNA discovered to date, and appears to be used by viruses that infect bacteria. Another large RNA revealed in the study, called HEARO, has a genetic structure that suggests it is part of a type of 'jumping gene' that can move to new locations in the bacterial chromosome."Read more of this storyat Slashdot.
theodp writes "In investigating the question of whether men are smarter than women, British researcher Adrian Furnham came up with some startling results. His analysis of some 30 studies showed that men and women are fairly equal overall in terms of IQ, but women underestimate their own intelligence while men overestimate theirs. Surprisingly, both men and women perceived men being smarter across generations — both sexes believe that their fathers are smarter than their mothers and their grandfathers are more intelligent than their grandmothers. And if there are children, both men and women think their sons are brighter than their daughters."Read more of this storyat Slashdot.

ACKyushu writes "Researchers from Helsinki University of Technology (Finland), University of New South Wales (Australia), and University of Melbourne (Australia) have succeeded in building a working transistor whose active region comprises only a single phosphorus atom in silicon. The results have just been published in Nano Letters. The working principles of the device are based on sequential tunneling of single electrons between the phosphorus atom and the source and drain leads of the transistor. The tunneling can be suppressed or allowed by controlling the voltage on a nearby metal electrode with a width of a few tens of nanometers."Read more of this storyat Slashdot.
John Bryson writes "Eating less of one amino acid might lengthen your life. There have been lots of previous studies showing that many species live long on highly restricted calories, but a lot of this benefit may be possible by only restricting one amino acid. Amino acids that have shown this have been tryptophan and methionine. A recent study, published online December 2 in Nature, a highly respected journal, may help explain some of the health benefits of restricted-calorie diets."Read more of this storyat Slashdot.
coondoggie writes "Looking to build strategic satellites in days if need be, rather than months, the Air Force is pushing forward with what it calls plug-and-play spacecraft. This week it awarded a $500,000 order to Northrop Grumman to begin designing the plug-and-play spacecraft 'bus' which will offer standard interfaces for a variety of payload components, much like a laptop computer that immediately recognizes new hardware when it's plugged in, Northrop stated. The order was awarded under a contract that has a ceiling of $200 million."Read more of this storyat Slashdot.
