Harvard
Robots by the dozen are prohibitively expensive, so actually testing how large swarms would work together is often limited to computer simulations. That's where Harvard's Kilobots are beginning to bear fruit – at a cost of US$14 each in batches of a thousand, they're a tenth the cost of their cheapest competitor. At such bargain-basement prices, Michael Rubenstein, Christian Ahler, and Radhika Nagpal at the Self-Organizing Systems Research Group have begun to build their own little robot army. Read More
Pill-sized device uses spinning laser to image the esophagus
Barrett’s esophagus is a precancerous condition typically caused by chronic exposure to stomach acid, and is usually diagnosed by inserting an endoscope down the patient’s throat. A tool has been developed, however, that should allow for a quicker, easier way of getting a good look at such peoples’ esophagus – it’s a swallowable capsule that contains a spinning laser.

There is new hope for those of us who have overindulged in loud bands and dread the prospect of old age spent with an ear trumpet clamped to the sides of our heads. Researchers from Massachusetts Eye and Ear and Harvard Medical School have been able to stimulate resident auditory hair cells to become new ones, resulting in partial hearing recovery in mice whose hearing has been damaged by noise trauma.

Many were skeptical when, back in 2007, Canadian company D-Wave announced that it had built the world's first commercially viable quantum computer. Now a study published in the August issue of Nature's Scientific Reports co-authored by D-Wave and Harvard researchers proves the D-Wave One is the real deal. Read More
Perfect optical absorber invented at Harvard University
Harvard Professor of Applied Physics Federico Capasso and his collaborators have invented a nearly perfect optical absorber. By coating a piece of sapphire with an exceedingly thin (180 nm) layer of vanadium dioxide (VO2), a surface is created that absorbs 99.75 percent of infrared light with a wavelength of 11.6 micron wavelength. Such optical absorbers can be tailored to enable a wide range of applications. Read More
Lab-grown brain tissue might lead to bioengineered implants
A team of researchers from MIT and Harvard Medical School have devised a cheap way of artificially growing three-dimensional brain tissues in the lab. Built layer by layer, the tissues can take on just about any shape and closely mimic the cellular composition of the tissue found in the living brain. The advance could allow scientists to get a closer look at how neurons form connections, predict how cells of individual patients will respond to different drugs, and even lead to the creation of bioengineered implants to replace damaged brain tissue.

U.S. study quantifies the effects of exercise on life expectancy
The benefits of regular exercise are well known, but what exactly are you getting in return for your efforts? A research a collaboration between the U.S.-based Harvard-affiliated Brigham and Women’s Hospital and the National Cancer Institute has attempted to answer this question by quantifying how much longer people live depending on the levels of exercise they engage in.

Biocompatible scaffolds, like those developed to stimulate the repair of heart tissue and bone and cartilage in the body, would normally need to be implanted surgically. Now bioengineers at Harvard University have developed a compressible bioscaffold that can be delivered via a syringe before popping back to its original shape inside the body. The material is also able to be loaded up with drugs or living cells that are gradually released as the material breaks down. Read More
Revealed: World Technology Network's innovators of 2012
The World Technology Network summoned leading thinkers to New York's TIME Conference Center on Monday and Tuesday to announce the winners of its 2012 World Technology Summit & Awards. The awards showcase the work of innovators across a diverse array of industry sectors and scientific fields. Gizmag reveals the list of winners, which includes no shortage of familiar faces.

Harvard researchers are getting closer to their goal of developing a controllable micro air vehicle called the Robobee. The tiny robot was already capable of taking off under its own power, but until now it was completely out of control. By adding two control actuators beneath its wings, the robot can be programmed to pitch and roll. Read More
