Do friends wear the same style of shoe or see the same movies because they have similar tastes, which is why they became friends in the first place? Or once a friendship is established, do individuals influence each other to adopt like behaviors?

Researchers from across Europe have united to build the largest quantum key distribution network ever built. The efforts of 41 research and industrial organisations were realised as secure, quantum encrypted information was sent over an eight node, mesh network.

It's a frequent scene in television crime dramas: Clever police technicians zoom in on a security camera video to read a license plate or capture the face of a hold-up artist. But in real life, enhancing this low-quality video to focus in on important clues hasn't been an easy task. Until now.

Faster computers, more secure information transfer, smarter sensors – all technologies that could benefit from a new, simpler way of manipulating light to convey much more information using fewer light beams and resources.

A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer.

A Memphis, Tenn., hospital confirmed Tuesday that Apple CEO Steve Jobs received a liver transplant there two months ago and said he is "recovering well and has an excellent prognosis."

Duke University computer scientist Susan Rodger is hoping ice skaters, cute animals and fearsome dragons will bring new talent to her field. With support from the National Science Foundation, she and collaborators nationwide are using the power of storytelling to draw younger students into programming.

Not using your computer at the moment? You can now donate your computer's idle time to cutting-edge biomedical research aimed at finding a cure for HIV, Parkinson's, arthritis, and breast cancer.

Do you poke, play or simply ignore? According to a new study by Queensland University of Technology, the popularity of a Facebook application will largely depend on whether you are male or female, and if it meets the criteria of being "cool."

Apple Inc. released a new iPhone today, aiming to tempt consumers with faster speed and more features as competitors crowd the market for Web-equipped phones.

Inspired by the behavior of the human eye, Boston College computer scientists have developed a technique that lets computers see objects as fleeting as a butterfly or tropical fish with nearly double the accuracy and 10 times the speed of earlier methods.

It’s been a persistent problem throughout human history: how do I compute things? From simple solutions like slash marks in the mud and the well-known abacus to very high tech super computers, thousands of methods have been developed to help perform calculations. None, however, have had the same impact as what we today know as simply the computer, the harbinger of the digital age.

Computer scientists at Harvard have developed a framework for studying the arrangement of tissue networks created by cell division across a diverse set of organisms, including fruit flies, tadpoles, and plants.

For more than 25 years, scientists in the Center for Complex Systems and Brain Sciences (CCSBS) in Florida Atlantic University’s Charles E. Schmidt College of Science, and others around the world, have been trying to decipher the laws of coordinated behavior called “coordination dynamics."

It's a familiar scene in airports and train stations. Hands full with luggage, briefcase, laptop or coat and there's something you need to remember, like the level and row numbers where you parked your car in the deck. What do you do?
