Qubits and Branes Share Surprising Features What do black holes and entangled particles have in common? Until about a year ago, physicists thought that the two entities existed in completely separate worlds. Then, in 2007, physicist Michael Duff from Imperial College London demonstrated a correlation between the entanglement of three qubits and the entropy of a black hole. In the past year, several studies have demonstrated even more connections. Monster founder sets sights on online obituaries (AP) -- Fourteen years ago, Jeff Taylor helped set off a tectonic shift in recruitment advertising by founding Monster.com, one of the first online companies to challenge a big profit source of newspapers. Maverick scientists probe Siberian forest mystery Was it a gigantic meteorite? A tremendous bolt of lightning? Perhaps the crash of a UFO the size of Tokyo? No one is certain of the answer to one of the 20th century's greatest scientific mysteries -- the "Tunguska Event" 100 years ago this week. Online service lets blind surf the Internet from any computer, anywhere Visions of future technology don't involve being chained to a desktop machine. People move from home computers to work computers to mobile devices; public kiosks pop up in libraries, schools and hotels; and people increasingly store everything from e-mail to spreadsheets on the Web. Stem cell research from an ethical point of view Stem cell research and the potential use of human embryonic stem cells in clinical therapy is a controversial issue which splits both scientific and public opinion. The current conflict over embryonic stem cells throughout the world deals particularly with the ethical implications of this promising, but delicate subject and the scientific manipulation of human life in its early stages of development. It is a symbolic struggle over the whole future of developmental biology - over how we will proceed with a wide range of research on human development. Alternative methods for gaining embryonic stem cells such as the Altered Nuclear Transfer (ANT) method developed by William B. Hurlbut, M.D., a member of The President's Council on Bioethics in Washington, D.C., are considered important steps torward embryonic stem cell research. Physicists Store Images in Vapor Books are written on solid pieces of paper for an obvious reason: the atoms in a solid don`t move around much, keeping the words and pictures in place for centuries. Trying to store letters and images in a gas medium, on the other hand, seems a little far-fetched. Atoms in a gas are constantly moving around, which would move the images around with them. N.M. school tries to reach students via podcast (AP) -- Students at a rural New Mexico school made a unique pledge last winter: Right hands raised, they promised to take care of their Zunes. Pioneer in field of molecular biology dies at 84 (AP) -- Gunther Stent, who helped pioneer the field of molecular biology as one of the first scientists to confirm the structure of DNA, has died. He was 84. Unable to focus? Welcome to our distracted society's attention deficit Understanding the science of attention and technology's role in eroding -- and perhaps someday improving -- our ability to focus Cell phones, Blackberries, e-mail, laptops allowing people to bring their work anywhere, news arriving in perfectly condensed and filtered snippets via the Internet and TV, never before has communication been so instantaneous and information distributed so quickly.
