Harvard's soft-bodied robot jumps up to 30 times its own height using internal gas explosi...

Most robots are built out of rigid materials, but a DARPA initiative to build soft-bodied robots that can squeeze into hard-to-reach places has led to the development of new types of the mechanical marvels. Harvard's Whitesides Research Group is working on a soft-bodied solution and has produced a squishy three-legged bot that can jump 30 times its height using the power of internal explosions.  Read More

The Bastard Hogberry was one of the inspirations for the color-changing fibers

Materials scientists at Harvard University and the University of Exeter have invented a new class of polymer fibers that change color when stretched. As is often seen in nature, the color is not the result of pigments, but rather comes from the interference of light within the multilayered fiber. Inspired by Margaritaria nobilis – also known as the Bastard Hogberry – the new fibers may lead to new forms of sensors, and possibly to smart fabrics whose color changes as the fabric is stretched, squeezed, or heated.  Read More

Blue light has been used to kill potentially-lethal Pseudomonas aeruginosa bacteria (pictu...

Over the past few years, blue light has allowed us to understand heart problems, control brain functions, and activate muscle tissue. Now, another biomedical function can be added to its list – because it’s known to have antimicrobial qualities, it’s been used to stop infections of the skin and soft tissues.  Read More

One hundred Kilobots move towards a light source

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

The swallowable capsule, and its tether

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.  Read More

Researchers have regenerated auditory hair cells in adult mammals for the first time (Imag...

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.  Read More

The D-Wave One quantum computing system (Photo: D-Wave)

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

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

MIT engineers have devised a way to stack neurons to form three-dimensional brain tissue (...

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.  Read More

US researchers have quantified how much longer people live when they are physically active...

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.  Read More
