An On/Off Switch for Sex and Violence RECENTLY DEVELOPED powerful, yet also delicate and refined, genetic tools can invasively probe nervous systems of animals, far surpassing the safer but much cruder techniques that psychologists and cognitive neuroscientists use to observe the human brain. Now in a remarkable series of experiments, researchers have located a trigger for aggression in mice—providing us with fresh insights into the workings of our human consciousness. You might object that mice and men are not the same and that studying the murine mind is different from studying the human mind. The amazing finesse and utility of contemporary molecular biology techniques are illustrated in recent experiments dealing with sex and power—the twin themes around which much of popular culture, psychoanalysis and art is centered. Aggression Center Our story starts in the hypothalamus, an ancient region of the brain, conserved throughout mammalian evolution. The first experiment is a molecular biology version of brain imaging.

True 3D display created using a laser and 50,000 dots per second – Computer Chips & Hardware Technology 3D capable displays are becoming pretty commonplace, but not everyone likes them. The problem is you either have to wear glasses to see the 3D, or are limited by the viewing angle with the non-glasses solutions. Even if you get it right, some people still feel sick after a while due to the way in which our eyes are being fed the 3D image. Burton Inc. is attempting just that and has demonstrated a new, true 3D display that uses a laser to create luminous points of light in 3D space. The technology used to create the display has been knocking around since 2006, and is a joint collaboration between Burton, the National Institute of Advanced Industrial Science and Technology (AIST), and Keio University. In this early prototype the display can project 50,000 dots per second and works at up to 15 frames per second. While the video below shows everything rendered in green, the system is actually capable of full color by using red, green, and blue lasers together. Read more at DigInfo TV
The Unselfish Gene The Idea in Brief Executives, like most other people, have long believed that human beings are interested only in advancing their material interests. However, recent research in evolutionary biology, psychology, sociology, political science, and experimental economics suggests that people behave far less selfishly than most assume. Evolutionary biologists and psychologists have even found neural and, possibly, genetic evidence of a human predisposition to cooperate. These findings suggest that instead of using controls or carrots and sticks to motivate people, companies should use systems that rely on engagement and a sense of common purpose. Several levers can help executives build cooperative systems: encouraging communication, ensuring authentic framing, fostering empathy and solidarity, guaranteeing fairness and morality, using rewards and punishments that appeal to intrinsic motivations, relying on reputation and reciprocity, and ensuring flexibility.
Mutated DNA Causes No-Fingerprint Disease Almost every person is born with fingerprints, and everyone's are unique. But people with a rare disease known as adermatoglyphia do not have fingerprints from birth. Affecting only four known extended families worldwide, the condition is also called immigration-delay disease, since a lack of fingerprints makes it difficult for people to cross international borders. In an effort to find the cause of the disease, dermatologist Eli Sprecher sequenced the DNA of 16 members of one family with adermatoglyphia in Switzerland . Seven had normal fingerprints, and the other nine did not. After investigating a number of genes to find evidence of mutation, the researchers came up empty-handed—until a grad student finally found the culprit, a smaller version of a gene called SMARCAD1. ( Get a genetics overview. ) The larger SMARCAD1 is expressed throughout the body, but the smaller form acts only on the skin . (See skin pictures .) American Journal of Human Genetics.
Welcome - The Rosetta Project Top 10 Popular Shot & Shooter Recipes | The Intoxicologist Today, September 22, marks the day for the fastest drinking record; Dustin Phillips of the United States consumed a 14 ounce bottle of Ketchup through a 1/4” straw in 33 seconds flat ten years ago. Ketchup seems a nasty ‘beverage’ to guzzle willingly, yet many enthusiastic participants flock to bars weekly to start (or end) the evening with the downing of a shot that none would eagerly sip slowly enough to take in the flavor or texture for a lingering moment on the tongue. Admittedly there are many shot recipes that make the conversion to cocktail easily. The Oatmeal Cookie shot is an outstanding example. However, many prefer shots and shooters too horrid to down without holding the nose or throwing them back feverishly with a beer chaser or *gasp* water back. I know…I mentioned the word ‘water’ in a cocktail post. Buttery Nipple 1 ounce Butterscotch Schnapps 1/2 ounce Irish Cream Pour Butterscotch Schnapps in bottom of a shot glass.

Frans de Waal on Political Apes, Science Communication, and Building a Cooperative Society | The Primate Diaries Portrait of de Waal by Nathaniel Gold “It’s the animal in us,” we often hear when we’ve been bad. But why not when we’re good? This is the question that has driven Frans de Waal for the past 30 years. From his pioneering research on alliance formation in Chimpanzee Politics , to reconciliation behavior in Peacemaking Among Primates and Good Natured , to the implications for human life and thought in Primates and Philosophers, de Waal has been seeking to understand the roots of moral behavior in the most political of animals. Unlike most of de Waal’s books, however, The Age of Empathy offers suggestions about how we can implement some of these moral lessons into our own society. For the past twenty years de Waal has lived and worked in Atlanta, Georgia where he operates the Living Links Center at the Yerkes National Primate Research Center of Emory University.

Visible Proofs: Forensic Views of the Body: Galleries: Media: Autopsy WARNING: Some people may find images from actual postmortem dissections disturbing. Viewer discretion advised. Videos on this page require either QuickTime Player or Windows Media Player. Postmortem dissection, or autopsy, was among the first scientific methods to be used in the investigation of violent or suspicious death. Autopsy remains the core practice of forensic medicine. The postmortem examiner surveys the body's surface, opens it up with surgical instruments, removes parts for microscopic inspection and toxicological analysis, and makes a report that attempts to reconstruct the cause, manner and mechanism of death.

Superhydrophobic spray means no more clothes to wash Ross Technology Corp is a company that specializes in steel products including non-slip flooring, security, and racks. For the tech enthusiast, that may sound a little boring, but then you hear about a byproduct of a solution they came up with to stop their steel products corroding. Metal corrodes when it comes into contact with liquid such as water, so Ross engineers set about coming up with a coating to keep liquid away from the steel. What they ended up with is a silicon-based spray that not only kept steel dry, it could also be applied to many different surfaces and materials. Rather than just concentrate on steel, Ross decided to create a new product based on the spray known as NeverWet, which we should all hopefully benefit from using soon. The spray actually uses nanoparticles and is superhydrophobic. NeverWet is being turned into a consumer product and will see a release next year, but we should also start seeing it applied to products too. via Lancaster Online and NeverWet
Yes, I know, it sounds crazy! Furthermore, it's difficult to think that they are workin on projects such as building new kind of DNA and to know that they only know about 4% of the fonction of the DNA. They are still stating that some sequences of the DNA is useless (just because they don't know more about it...). Please, mother nature, forgive them because they don't shit about what they do but kick their asses to help them understand that life is all about respecting things as they are. by ekolibrium Apr 24
APG I'm actually pretty skeptical of this article, it claims MIT found a way to edit DNA sequences and that they can basically use that to create organisms to their own will, like they could make DNA that codes for proteins not found in nature or create super bacteria to help us fight viruses. It all seems too sci-fi to me. by sc215 Apr 23
