This curious feeling of knowing has settled over most of us. In a group, someone always seems to be “checking” something in the conversation, piping up with handy facts culled from a rapid consultation with the Great and Powerful Man Behind the Curtain. I’ve attended more than one nerdy party where everyone had a link open and we were all talking about things we didn’t know until we were prompted by our conversation to look them up.
The promise is more than a marketing boast. Aided by microchip transmitters, heat sensors and a fast-growing form of wireless communication, the boast is a measurable fact. Inside each Ocado delivery van is a SIM-card module the size of a postage stamp that monitors the air temperature. The sensor sends data to a computer used by fleet managers back at headquarters near London every few minutes.
THE easiest way to learn a new game is to watch someone else play it - and now computers can do the same. Łukasz Kaiser , who studies logic and games at Paris Diderot University in France, has developed software that learns to play games such as Connect 4 and noughts-and-crosses by watching videos of humans playing. As it watches, it uses standard image-processing tools to recognise changes in the separate board squares and pieces of a game, while ignoring extra details like human hands. The videos allow the system to learn the rules by logging what the board looks like when a game has been won, and what count as legal moves.
A neural network created by connecting 16,000 computer processors appears to support biologists' theories on how the human brain identifies objects. / iStockphoto (CNET) Google scientists working in the company's secretive X Labs have made great strides in using computers to simulate the human brain. Best known for inventing self-driving cars and augmented-reality eyewear, the lab created a neural network for machine learning by connecting 16,000 computer processors and then unleashed it on the Internet. Along the way, the network taught itself to recognize cats. While the act of finding cats on the Internet doesn't sound all that challenging, the network's performance exceeded researchers' expectations, doubling its accuracy rate in identifying objects from a list of 20,000 items, according to a New York Times report .
Artificial intelligence could help us better understand the effects of psychedelic drugs, by analysing narrative reports written by people who are using them. Scientists barely understand how existing psychedelic drugs work to alter perception and intensify emotions, let alone keep pace with new ones flooding the market – often sold as "bath salts" or "herbal incense". Enter artificial intelligence. Matthew Baggott of the University of Chicago and colleagues used machine-learning algorithms – a type of artificial intelligence that can learn about a given subject by analysing massive amounts of data – to examine 1000 reports uploaded to the website Erowid by people who had taken mind-altering drugs.

Carl Franzen Forget saving files to flash drives and cloud servers. Now, digital information can be stored in the DNA of living organisms, thanks to a breakthrough discovery by researchers at Stanford University in California. A trio of scientists successfully demonstrated the ability to flip the direction of DNA molecules in sample E.coli bacteria in two directions, mimicking the “1s” and “0s” of binary code, which is at the root of all modern computer calculations. “Essentially, if the DNA section points in one direction, it’s a zero. If it points the other way, it’s a one,” said Pakpoom Subsoontorn, a bioengineering graduate student at Stanford involved in the research, in an article on the Stanford School of Medicine website .
24 October 2010 Last updated at 20:02 ET By Lakshmi Sandhana Technology journalist Rajesh Rao is a man who believes that the best type of robotic helper is one who can read your mind. In fact, he's more than just an advocate of mind-controlled robots; he believes in training them through the power of thought alone. His team at the Neural Systems Laboratory, University of Washington, hopes to take brain-computer interface (BCI) technology to the next level by attempting to teach robots new skills directly via brain signals. Robotic surrogates that offer paralyzed people the freedom to explore their environment, manipulate objects or simply fetch things has been the holy grail of BCI research for a long time. Dr Rao's team began by programming a humanoid robot with simple behaviours which users could then select with a wearable electroencephalogram (EEG) cap that picked up their brain activity.
22 August 2011 Last updated at 20:42 ET By Jane Wakefield Technology reporter Algorithms are spreading their influence around the globe If you were expecting some kind of warning when computers finally get smarter than us, then think again. There will be no soothing HAL 9000-type voice informing us that our human services are now surplus to requirements.
Aside from state-of-the-art graphics, the Unreal Engine 3 already has a plethora of programmers, artists, modders, and other designers that have been creating with it for years Image Gallery (9 images) Video game developer, Epic Games, is known for giving players realistic experiences thanks to its popular Unreal Engine platform. But while games like Batman: Arkham City and Gears of War are certainly entertaining, virtually beating up thugs and fighting subterranean creatures doesn't exactly translate into real world skills.

Stuart Isett for The New York Times Pilots using the technology will no longer need to circle overhead awaiting clearance to land, saving fuel and reducing delays.
If the movie 2001: A Space Odyssey taught us anything, it’s that computers know when we’re telling a lie. While that may not actually be the case for most computers in real life, it could be if they’re running a program created by scientists from the University at Buffalo. Building on a previous psychological study, the team produced software that allowed a computer to assess a speaker’s eye movements, to determine whether or not they were telling the truth in a prerecorded conversation. It turns out that the computer was able to correctly able to spot their lies with 82.5% accuracy. According to the researchers, a trained human interrogator only manages a success rate of about 65%.
Children are sometimes referred to as “sponges,” not because they live off our earnings, but because of their remarkable ability to learn things quickly. Psychologists believe this is because their brains are still wired for learning and exploration – essential qualities for building neural connections – whereas adult minds tend to focus on specific goals, at the expense of imagination and curiosity. Now, scientists from the University of California, Berkeley are studying the cognitive functions of babies, toddlers and preschoolers, in hopes of using their findings to make computers think more like humans. Through a number of experiments, the research team has discovered that children are quite adept at testing hypotheses, detecting statistical patterns, and drawing conclusions while at the same time adapting to changes.
