Robotic surgery and computer-assisted medicine are already doing amazing things right now -- just look at the da Vinci Surgical System! Are you ready to ditch the hospital and buy a robot surgeon for the home? Let's say you have to have a dangerous surgical procedure. Let us know your decision and why in the comments below! Alright, medical technology is getting weirder by the day.

The pictures of the brightly coloured marine life were captured by researchers in Antarctica who are working on a better understanding of the impact of acidification on marine life on the sea floor. The pictures were captured by researchers in Antarctica who are working on a better understanding of the impact of acidification on marine life on the sea floor. The study was carried out near Australia's Casey research station, where marine life exists in water that is -1.5 degrees Celsius (29.3 degrees Fahrenheit) year round and covered in 1.5 metres (nearly five feet) of sea ice for 10 months of the year Angela Rye shares video of her invasive ordeal with TSA agent Boeing cargo plane overshoots runway before crashing in Colombia Male guests in a Chinese wedding flock to harass a bridesmaid Girl shouts at her poor Grandpa over her iPhone appointment Prisoner batters officer who finds him recording show on laptop Couple surprise family members with new SECRET baby Large explosion at fireworks market in Tultepec, Mexico.

A tiny crack in one of Antarctica's ice sheets has now grown 70 miles long and more than 300 feet wide, and it's causing an iceberg the size of Delaware to break off of the continent. The crack is in one of the Larsen ice sheets, which NASA has been tracking since a large piece broke off in 1995. Larsen C is expected to break away soon, which could have a major impact on the rest of the sheet.

About 20 percent of youth in the United States live with a mental health condition, according to the National Institute of Mental Health. The good news is that mental health professionals have smarter tools than ever before, with artificial intelligence-related technology coming to the forefront to help diagnose patients, often with much greater accuracy than humans. A new study published in the journal Suicide and Life-Threatening Behavior, for example, showed that machine learning is up to 93 percent accurate in identifying a suicidal person. The research, led by John Pestian, a professor at Cincinnati Children's Hospital Medical Center, involved 379 teenage patients from three area hospitals. Each patient completed standardized behavioral rating scales and participated in a semi-structured interview, answering five open-ended questions such as "Are you angry?" to stimulate conversation, according to a press release from the university.

Artificial Intelligence is a branch of computer science concerned with making computers behave like humans and pursues to create the computers or machines intelligent as human beings. It deals with the simulation of intelligent behavior in computers. It is the capability of a machine to imitate intelligent human behavior. According to the father of AI, John McCarthy, it is "The science and engineering of making intelligent machines, especially intelligent computer programs". AI is a way of making a computer, a computer-controlled robot, or a software think intelligently, in the similar manner the intelligent humans think.

Community detection in networks is an important problem in many applied areas. In this paper, we investigate this in the presence of node covariates. Recently, an emerging body of theoretical work has been focused on leveraging information from both the edges in the network and the node covariates to infer community memberships. However, so far the role of the network and that of the covariates have not been examined closely. In essence, in most parameter regimes, one of the sources of information provides enough information to infer the hidden cluster labels, thereby making the other source redundant. To our knowledge, this is the first work which shows that when the network and the covariates carry "orthogonal" pieces of information about the cluster memberships, one can get improved clustering accuracy by using them both, even if each of them fails individually.

Several years ago, I attended a Buddhist retreat in which I was introduced to the idea of the "retinue," a constellation of influential and supportive people whom one imagines in an enveloping cloud as one meditates. I took the concept one step further and decided to create an actual photo montage that I could hang on the wall above my desk: my childhood piano teacher, my high school English teacher, my rabbi, mentors in science, writers who encouraged me--in all, 20 people who had profoundly influenced me. Some members of my retinue were still living, some not. In some cases I could find the photographs myself. In others, I had to contact the mentors. When I finally tracked down William Gerace, who introduced me to physics nearly 50 years ago, he was puzzled as to why I should desire such a montage. We had not spoken for decades. Reluctantly, he sent me an old, out-of-focus photo of himself, dating back to the days when I knew him. Now, Gerace is a professor of science education at the University of North Carolina at Greensboro, after a 30-year career as a professor of physics at the University of Massachusetts Amherst, during which time he made the transition from theoretical nuclear physicist to leader in science education and co-founder of the Scientific Reasoning Research Institute at the University of Massachusetts, Amherst. When I knew him, in the late 1960s, he was a lowly instructor in physics at Princeton, where he had recently received his Ph.D. I was an undergraduate. The photo shows a man in his late 20s, about 5 feet 6, slight in build, dark hair beginning to thin, dressed in a button-down shirt and blue sweater, and a Mona Lisa smile. Each new mathematical technique Bill taught us was offered with the enthusiasm of a 12-year-old boy showing his friend a strange new butterfly. I first met Bill Gerace during a physics lab my sophomore year.

It's been five years since NASA ended the Spirit rover's mission, but now, researchers say the robot may have discovered traces of life during its Mars investigation. A team of geoscientists has discovered that silica deposits from a region on the red planet dubbed'Home Plate' closely resemble those that form in Chilean hot springs at El Tatio. On Earth, these complex finger-like structures arise from a combination of biological and non-biological activity, suggesting a similar process may have taken place on Mars. The researchers compared opaline silica structures found at Home Plate (on left) with those from hot spring discharge channels at El Tatio (on right). The silica deposits on Mars were discovered after Spirit's right front wheel failed in 2007, forcing the robot to drag it across the ground like a plow near Home Plate, an eroded deposit of volcanic ash.

They are wise-cracking companions, able to communicate in more than six million languages. Others are bent on enslaving or destroying humanity, deeming themselves better, more rational caretakers of the Earth in light of our irrational behaviors. Pilot or garbage man, soldier or slave, hero or villain--robots have played every role imaginable in popular science fiction for nearly a century. In the 21st century, real-life robots inspired by their fictional counterparts are beginning to take starring roles in everyday life. Several companies, Google among them, are testing autonomous cars (unfortunately, there is no indication that they will be able to travel into the past or future anytime soon).
