In this video of a mouse embryo, made 8.5 days after conception and one day after the heart has begun to form, the heartbeat is visible. The video was made using a variation on a technique called optical-coherence tomography. It’s being used by researchers at the University of Houston to take the highest resolution video yet of the developing mammalian heart. Their goal is a better understanding of why one percent of US infants are born with cardiovascular problems.
Within this game, software automatically displaces virtual objects so that players will not interfere with one another’s physical space. Called Redirected Motion, the technique could help in other situations where users share an augmented reality space.
U.K. readers of Templar Publishing’s Drake’s Comprehensive Compendium of Dragonology can use a Web camera with their book to control an on-screen animation of a dragon.
Researchers at the University of Oxford have developed an object-recognition system that successfully tracks multiple objects in an indoor space.
Scientists grew cardiac muscle cells on a thin polymer film, then tested the cells’ ability to contract. As they contract, the cells distort the shape of the polymer.
How my personal experiences prompted "Prescription: Networking."
Biomedical editor Emily Singer had a diffusion tensor scan, a variation of MRI that allows scientists to visualize the brain’s white matter, at UCLA. Neuroscientist Andrew Frew used brain imaging software from BrainLab to create these movies, highlighting different sections of white matter.
Over the last several years, vast amounts of natural gas have been found in the Marcellus shale that lies underneath vast areas of western New York, western and northern Pennsylvania, and parts of Ohio and West Virginia. If geologists are right, the Marcellus shale could be the world’s second-largest natural-gas field in the world. The natural gas is held tightly trapped in the shale, but advanced drilling techniques have made it economical to drill for the gas. Much of the activity is centered in the counties south of Pittsburgh.
Richard Haier, a psychologist and emeritus professor at the University of California, Irvine, explains how brain imaging is shedding light on intelligence.
Berkeley researcher Cyrus Wadia talks about his vision for the future of solar energy and demonstrates how to make a solar cell from fool’s gold.
