Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable. The development of such a device, described as an 'antimagnet', could offer many beneficial applications, such as protecting a ship's hull from mines designed to detonate when a magnetic field is detected, or allowing patients with pacemakers or cochlear implants to use medical equipment. In their study, published today, Friday 23 September, in the Institute of Physics and German Physical Society's New Journal of Physics, researchers have proved that such a cloak could be built using practical and available materials and technologies, and used to develop an array of applications.

March 21, 2012 A new Walden University survey shows that “think globally, act locally” has become a worldwide mentality, with a majority of citizens around the world (73%, on average) agreeing that what happens in other parts of the world can impact their local community. The global survey also found high levels of engagement in social change, with three-quarters of adults (75%, on average) involved during the past six months, which most commonly included donating money, goods or services (41%, on average).

Today the US Food and Drug Administration (FDA) weighed the benefits and risks of what could be the first HIV prevention pill to hit the market. A decision from the FDA is expected June 15 . Scientists on the FDA’s Antiviral Drugs Advisory Committee heard from investigators who led NIH and CDC-sponsored clinical trials on the drug Truvada, as well as doctors, patient advocates, and Gilead Sciences, the drug’s maker. Just before 7pm EST, 19 of the 22 committee members agreed that, despite any risks, Truvada would be useful in preventing HIV for men who have sex with men, and for HIV-negative individuals with HIV-positive partners. Opinions on the drug’s use for other risk groups reflected a greater uncertainty, with 12 members voting in favor of Truvada, 8 voting against it and 2 abstains. Condoms provide better protection against HIV than Truvada, which was approved for HIV as a therapy in 2004.

Scientists are irked over a paper claiming, as The New York Times reported on Monday, that “ DNA’s power to predict illness is limited .” “Yes,” geneticists have replied. “What else is new?”
Quantum teleportation , or entanglement-assisted teleportation , is a process by which a qubit (the basic unit of quantum information) can be transmitted exactly (in principle) from one location to another, without the qubit being transmitted through the intervening space. It is useful for quantum information processing , however it does not immediately transmit classical information , and therefore cannot be used for communication at superluminal (faster than light) speed. Quantum teleportation is unrelated to the common term teleportation - it does not transport the system itself, and does not concern rearranging particles to copy the form of an object.

Teleportation - Wikipedia, the free encyclopedia
Teleportation is a term that refers to a number of theories and notions concerning the transfer of matter from one point to another without traversing the physical space between them, similar to the concept apport , an earlier word used in the context of spiritualism. [ citation needed ] [ edit ] Etymology The word teleportation was coined in 1931 [ 1 ] [ 2 ] by American writer Charles Fort to describe the strange disappearances and appearances of anomalies , which he suggested may be connected. He joined the Greek prefix tele- (meaning "distant") to the Latin verb portare (meaning "to carry"). Fort's first formal use of the word was in the second chapter of his 1931 book, Lo! : "Mostly in this book I shall specialize upon indications that there exists a transportory force that I shall call Teleportation ."

Grand Challenges for Engineering
With input from people around the world -- much of it on this website -- an international group of leading technological thinkers were asked to identify the Grand Challenges for Engineering in the 21st Century. Their conclusions created this website. From urban centers to remote corners of Earth, the depths of the oceans to space, humanity has always sought to transcend barriers, overcome challenges, and create opportunities that improve life in our part of the universe. In the last century alone, many great engineering achievements became so commonplace that we now take them mostly for granted.
By gluing radio chips to the backs of 800 honeybees, researchers proved that Neonicotinoid pesticides interfere with their behavior. Greg Laden reports that bees exposed to the common aphid-killer "forage abnormally, have 'olfactory memory' problems, are easily disoriented and become poor learners." Fewer of them ever return to the colony.

"How did a suicidal robot end up here?" It had taken over 20 years of painstaking preparation and research to plan his suicide. He had to learn everything there was to know about the science of sentience. read more It was just how the world worked: you get to time travel, but do you end up chatting with Cleopatra?We are pleased to announce that Damn Interesting contributor Ben Taylor has just published a shiny new book that is sure to be the first in what we hope will become a long and lustrous book-publishing career. Apocalypse on the Set retells nine true stories of film-making enterprises which have endured calamity, ruin, humiliation, or some engrossing combination thereof. It’s filled with fremdschämen, schadenfreude, and other obscure Germanic emotions. We encourage our readers to buy this book because our readers have outstanding taste. Alongside Memphis International Airport in Tennessee there lies a sprawling complex filled with hundreds of miles of conveyor belts, thousands of employees, and millions of parcels. A steady stream of cargo planes–often hundreds per day–carries in cargo from around the world to be sorted and redistributed.

Increased Death Risk From Red Meat While quite a few studies have found an increased risk of assorted diseases and death from eating red meat some of those studies lumped together unprocessed and processed meat. So I've long wondered whether the signal against unprocessed meat is strong.SciTech Daily Review - science, news, technology, future developments, innovations, opinions, review
