<p>3-D wire frame models of the San Diego airport can be rendered from satellite images.

The Pentagon is assembling aerial imaging, geologic, terrain, and intelligence data into a 3-D scene that lets military planners and pilots preview missions, navigating the virtual scene from ground level to 40,000 feet at speeds up to 1,400 miles per hour.

Other software renders 3-D images of cityscapes that allow law enforcement agents to move around in the virtual cities and determine line-of-sight and distances between… read more

Intelligent Mistakes: How to Incorporate Stupidity Into Your AI Code

March 19, 2009

Improving the believability of AI opponents in games can be achieved by upping their use of “intelligent mistakes,” says game developer Nic West.

NASA Aircraft Enlisted to Fight Wildfires

October 29, 2007

NASA’s Ikhana took off Wednesday morning from Edwards Air Force Base, Calif., on a 10-hour mission to observe seven wildfires still raging in the southern part of the state, using an onboard visible and near- and far-IR sensors to collect data, process it into images, and send those via satellite to firefighting command centers in real time.

That means it can see in the dark and cut through a… read more

IBM to Provide Access to Blue Gene Supercomputer on Demand

March 14, 2005

IBM has announced the availability of its Blue Gene supercomputing system, the most powerful supercomputer, at its newest Deep Computing Capacity on Demand Center in Rochester, MN.

Customers and partners can remotely access the Blue Gene system through a secure, dedicated Virtual Private Network and pay only for the amount of capacity reserved, with peak performance of 5.7 teraflops.

CG idols mean no human is required

November 30, 2001

Virtual Japanese idol Yuki Terai is a well-known example of a growing group of virtual personalities with very rich careers.Like her predecessor Kyoko Date, and her contemporary American counterpart Ramona, the 17-year-old lover of strawberries and jazz is a recording artist with several CDs and videos under her belt.

Mainstream acceptance in Japan began when she appeared in a toothpaste commercial. When it hit the air she not only… read more

The Civil Heretic

March 26, 2009

Physicist Freeman Dyson dismisses the threat of global warming — an ultimately benign occurrence in what Dyson says is still “a relatively cool period in the earth’s history.”

Rising carbon-dioxide levels in the atmosphere are a sign that “the climate is actually improving rather than getting worse,” because carbon acts as an ideal fertilizer promoting forest growth and crop yields.

If needed, carbon-eating trees could be genetically engineered… read more

Appetite Regulation Molecule Found

November 8, 2007

Researchers from the Centre for Immunology at St Vincent’s Hospital of Sydney, the University of New South Wales, and the Garvan Institute of Medical Research have developed a novel way to control the extreme weight loss common in late stage cancer, giving people the strength to survive treatment and improve their chances of recovery.

They found that most common cancers produce large amounts of a molecule known as MIC-1,… read more

Alien Planets Show Themselves for First Time

March 23, 2005

Astronomers have seen light from extrasolar planets for the first time.

The planets, in the constellations constellation Pegasus and Lyra, were discovered by comparing measurements of infrared light made while the planet and star were both visible and while the planet was hidden behind the star.

Bionic Eyes

January 5, 2002

Using space technology, scientists have developed extraordinary ceramic photocells that could repair malfunctioning human eyes.

Scientists at the NASA-sponsored Space Vacuum Epitaxy Center (SVEC) in Houston are experimenting with thin, photosensitive ceramic films that respond to light much as rods and cones do. Arrays of such films, they believe, could be implanted in human eyes to restore lost vision by serving as substitutes for bad rods and cones.… read more

Robot love: South Korea to build robot theme parks

November 14, 2007

South Korea officials today said they hope to build two robot theme parks for $1.6 billion by 2013, saying they consider robotics to be one of South Korea’s key growth industries, emphasizing “service robots” that can clean homes and offer up entertainment.

Scan ‘shows if people trust you’

April 6, 2005

MRI brain scans of volunteers playing a money game showed that a brain region called the caudate nucleus lights up when it receives or computes data to make decisions based on trust.

The Increase in Chip Speed Is Accelerating, Not Slowing

February 4, 2002

The trajectory of desktop PC performance increases of the last two years will not slow in the near future, but actually accelerate, based on an expected announcement by Intel Corp. at the International Solid State Circuits Conference. Intel will present a paper today detailing a portion of a microprocessor chip that has performed at up to 10 gigahertz at room temperature —- the fastest calculating speed yet reported… read more

Science’s most powerful computer tackles first questions

April 9, 2009

The first research projects for the Jaguar supercomputer (at 1.64 petaflops, second only to the 1.7 petaflop Roadrunner), located at Oak Ridge National Laboratory, are focused on 21 environmental issues, such as climate models and synthesizing biofuels from waste plant material.

A Wiring Diagram of the Brain

November 20, 2007
Scientists are developing new ways to study the tangled web of neurons in the brain. (Kevin Briggman, Moritz Helmstaedter, Winfried Denk Viren Jain, Joseph Murray, Srini Turaga, and Sebastian Seung)

New technologies that allow scientists to trace the fine wiring of the brain more accurately than ever before could soon generate a complete wiring diagram–including every tiny fiber and miniscule connection–of a piece of brain.

Dubbed connectomics, these maps could uncover how neural networks perform their precise functions in the brain, and they could shed light on disorders thought to originate from faulty wiring, such as autism… read more
