DARPA researchers have demonstrated a new five-micron-pixel long-wave infrared (LWIR) camera that could make this class of camera smaller and less expensive. (A micron is a millionth of a meter.)

The military uses LWIR (also know as “far IR”) cameras as thermal imagers to detect humans at night. These cameras are usually mounted on vehicles as they are too large to be carried by a… read more

Engineers at the University of California, San Diego have invented a “nanosponge” capable of safely removing a broad class of dangerous toxins from the bloodstream — including toxins produced by MRSA, E. coli, poisonous snakes and bees.

These nanosponges, thus far studied in mice, can neutralize “pore-forming toxins,” which destroy cells by poking holes in their cell membranes. Unlike other anti-toxin platforms that need to… read more

Cancer centers racing to map patients’ genes

April 22, 2013

Human genome sequence

Major academic medical centers in New York and around the country are spending and recruiting heavily in what has become an arms race within the war on cancer.

The investments are based on the belief that the medical establishment is moving toward the routine sequencing of every patient’s genome in the quest for “precision medicine,” a course for prevention and treatment based on the special, even unique characteristics of… read more

Making text more readable on wearable displays

April 22, 2013

Google_Glass_detail

Osaka University researchers have developed a text-display algorithm that places the current message on the darkest region in view at any given moment and in a readable color, making wearable displays like Google Glass more usable, New Scientist reports.

This is done using the headset’s camera, which plots a constantly changing heat map of viable on-screen reading locations. The algorithm can also split up a message into two… read more

The future of health care could be found in a tiny, paper-thin skin patch that collects vital information.

The Bio-patch sensor developed by KTH Royal Institute of Technology researchers is inexpensive, versatile, and comfortable to wear. It measures bioelectrical signals through the skin when applied to different parts of the body.

“On the chest it provides electrocardiography (ECG), on the skull it measures brainwaves… read more

Will robots create new jobs when they take over existing ones?

April 19, 2013

rethink_baxter

At a robotics industry event organized by business blog Xconomy in Menlo Park last week, people working on better industrial robots claimed their robotics technology will actually boost the U.S. economy and create more jobs, even if some jobs do disappear forever, MIT Technology Review reports.

“We’re replacing jobs that people don’t want to do and really shouldn’t be doing,” said Aldo Zini, whose company… read more

New microbatteries developed by researchers at the University of Illinois at Urbana-Champaign, out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

“This is a whole new way to think about batteries,”  said William P. King, the Bliss Professor of mechanical science and engineering. “A battery can [now] deliver far more power than anybody ever thought.… read more

Astronomers using a world-wide collection of telescopes have discovered the most prolific star factory in the Universe, surprisingly in a galaxy so distant that they see as it was when the Universe was only six percent of its current age.

The galaxy, dubbed HFLS3, 12.8 billion light-years from Earth, is producing the equivalent of nearly 3,000 Suns per year, a rate more than 2,000 times that of… read more

When does your baby become conscious?

April 19, 2013

New research shows that babies display glimmers of consciousness and memory as early as 5 months old, Science Now reports.

Studies on adults show a particular pattern of brain activity: When your senses detect something, such as a moving object, the vision center of your brain activates, even if the object goes by too fast for you to notice. But if the object remains in your visual… read more
