Seeing Machine for the Blind
CAMBRIDGE, Mass., Jan. 14, 2009 – A visually challenged MIT poet has unveiled a “seeing machine” that allows some people who are blind or visually challenged to be able to see. Elizabeth Goldring, also an artist and a senior fellow at MIT’s Center for Advanced Visual Studies, began working on the device with fellow colleagues more than 20 years ago. What went from being a large diagnostic device costing some $100,000 to a $4,000 desktop version is now portable and inexpensive. According to Goldring, her team can produce a...
Dreadlocks with Kung Fu Grip
CAMBRIDGE, Mass., Jan. 9, 2009 -- Researchers have found that dunking synthetic, nanosize hairs into a liquid and allowing the liquid to evaporate can coax the nanobristles to twist together like dreadlocks, sticking to each other or to an object in their center with a tenacious...
Repulsive Casimir Measured
CAMBRIDGE, Mass., Jan. 7, 2009 -- For the first time, physicists have measured a repulsive Casimir force that could be tailored for a wide range of new nanotechnology applications. The study, which builds on previous work on the quantum mechanical force, was led by Federico Capasso,...
Applications: Keeping an Eye on Lasik
Jan 1, 2009 — Research into lasik (laser-assisted in situ keratomileusis) refractive eye surgery indicates that, besides focusing on improving the procedure, the trend is moving toward developing different techniques or, in some cases, going back to one that...
Technology: Smarter, Better, Faster, Greener
Jan 1, 2009 — Technology helps us see, understand and manipulate our world; it helps us communicate from afar; and it helps us shop for shoes without ever setting foot in a mall. And none of it would be possible without the dedicated, forward-thinking researchers...
A step closer to stopping E.coli

Liquid lens: water + sound = fast focusing
TROY, N.Y. – An adaptive liquid lens that is powered by water, sound and surface tension can capture 250 pictures per second using very little energy, and its ability to focus extremely quickly (in 0.01 seconds) makes it promising for use in cell phone cameras,...
Revealing the hidden spectrum
SANTA BARBARA, Calif. – Much like fishermen wear polarized sunglasses to see past the reflective glare of the water’s surface to spot their sport, astronomers use polarized filters in telescopes to isolate the reflected light of accretion disks, or gas formations that...
Science needs a feminine touch
WATERTOWN, Mass. – Despite the debate over its cause, there is general agreement that women are underrepresented in the fields of science and engineering. Theories about the cause of the discrepancy range from lack of interest to subtle discrimination, with many...
Semiconductor manufacturing goes green
AUSTIN, Texas – A recent symposium conducted by ISMI, the Austin-based Sematech manufacturing subsidiary, yielded good news. The industry is going green, with environmentally friendly factories springing up around the world and energy-efficient tools being...
Solving a sticky problem in power plants
STATEN ISLAND, N.Y. – As energy costs rise and the economy falls, there is no room for inefficiency in power production. In coal-fired power plants, a problem known as slagging occurs when coal ash minerals get sticky and latch onto the boiler tubes that transport...
Stereo Displays: Trading the Movies for Real-World Applications
Dec 1, 2008 — Most people were exposed to stereo displays through 3-D movies, which were the rage in the 1950s and now are enjoying a revival, thanks to the Imax process and animated films. Today, however, the technology has moved on to encompass a wide variety...

Almost valet service
Nov 1, 2008 — CENTURY CITY, Calif. – Finding an empty spot in a parking garage can be a pain. You drive up and down and around, finally see an open space, pull up – and it’s a handicapped spot. It’s annoying, it’s frustrating, and it could be a thing of the...
Congress fast-tracks laser weapons
Nov 1, 2008 — WASHINGTON – As part of the $612.5 billion 2009 defense appropriations bill signed into law by President George W. Bush in mid-October, Congress fast-tracked Defense Science Board (DSB) recommendations that the military focus on the promise of...
Eyeballing security
Nov 1, 2008 — HAMAMATSU, Japan – Our unconscious eye reflex movements are unique to each of us, so unique that they could be used as our key to positive identification in security settings. Even if a third party with ill intent – an infiltrator, if you will –...
Face to face: forensic artists
Nov 1, 2008 — DUNDEE, Scotland – Beauty, they say, is skin deep. Identity can go right down to the bone. When a murder victim is unidentified, authorities can turn to forensic artists who specialize in facial reconstruction – experts who can take a human skull...
It may sound corny, but …

Upgrading the precision of a nanopositioner
Nov 1, 2008 — WEST LAFAYETTE, Ind. – The common laboratory nanopositioner moves very small items easily and precisely. Most nanomanipulators have a resolution of about 10 to 20 nm, resulting from thermally induced vibrations. Since single atoms are about a tenth...
Voters approved after a quick scan
Nov 1, 2008 — RALEIGH, N.C. – The same technology that helps keep inventories straight in stores is now being used in North Carolina to make sure that every vote counts. That fundamental goal can be hard to achieve; it’s impossible if a voter uses the wrong...
