January 21, 2013

Wrap 920AR (credit:

People who’ve lost sight in one eye can still see with the other, but they lack binocular depth perception.

A pair of augmented reality glasses being built at the University of Yamanashi in Japan artificially introduces a feeling of depth in a person’s healthy eye, MIT Technology Review reports.

The researchers created software that makes use of the twin cameras in a Vuzix Wrap… read more

A computerized house that generates as much energy as it uses

NIST unveils net-zero energy residential test facility to improve testing of energy-efficient technologies
September 18, 2012

NIST Net Zero Energy Residential Test Facility

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) has unveiled a laboratory in the form of a typical suburban home, designed to demonstrate that a family of four can generate as much energy as it uses in a year.

The two-story, four-bedroom, three-bath “Net-Zero Energy Residential Test Facility“ was built to U.S. Green Building Council LEED Platinum standards — the highest standard for sustainable… read more

Stanford Engineering‘s Center for Turbulence Research (CTR) has set a new record in computational science by successfully using a supercomputer with more than 1.5 million computing cores to solve a complex fluid dynamics problem: the prediction of noise generated by a supersonic jet engine.

Joseph Nichols, a research associate in the center, worked on the newly installed Sequoia IBM Bluegene/Q system at Lawrence Livermore National Laboratories (LLNL)… read more

Fukushima fuel pool is urgent national security issue for America, ‘top threat facing humanity’

May 7, 2012

Fukushima

After visiting Fukushima, Senator Ron Wyden warned that the situation was worse than reported, Washington’s Blog reports … and urged Japan to accept international help to stabilize dangerous spent fuel pools.

Wyden said that the spent fuel is a national security threat to the U.S.: “The radiation caused by the failure of the spent fuel pools in the event of another earthquake could reach the West… read more

GOP lawmaker seeks ‘virtual Congress’ with telecommuting plan

Under a resolution Pearce introduced on Thursday, Rep. Steve Pearce (R-N.M.) wants to create a “virtual Congress,” where lawmakers would leverage videoconferencing and other remote work technology to to hold hearings, debate and vote on legislation virtually from their home district offices, The Hill reports.

Pearce says the resolution would eradicate the need for members to jet back and forth from their districts to Washington each weekend. This… read more

The real Limitless drug

April 8, 2013

Modafinil (Provigil in the United States) was first approved by the FDA in 1998 for the treatment of narcolepsy, but since has become better known as a nootropic, a “smart drug,” especially among entrepreneurs, says New York magazine.

Rumored to be the model for the fictional pills in the movie Limitless, no scientist has conducted a study of its long-term effects on healthy brains yet. At the very… read more

A new method for producing clean hydrogen

May 23, 2013

TEM_image_Au-a-Fe2O3_catalyst

Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.

While hydrogen is ubiquitous in the environment, producing and collecting molecular hydrogen for transportation and industrial uses is expensive and complicated. Just as importantly, a byproduct of most current methods of producing hydrogen is carbon monoxide, which is… read more

NASA’s Kepler mission discovers 715 new planets

NASA’s Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets (planets… read more

Events in the future seem closer than those in the past

We tend to feel closer to the future because we feel like we’re moving toward it

We say that time flies, it marches on, it flows like a river — our descriptions of time are closely linked to our experiences of moving through space.

Now, new research suggests that the illusions that influence how we perceive movement through space also influence our perception of time. The findings provide evidence that our experiences of space and time have even more in common than previously… read more

Hubble sees cloudy ‘super-Earth’ 40 light-years away

January 2, 2014

GJ1214b

Two teams of scientists using NASA’s Hubble Space Telescope report they have characterized the atmospheres of a pair of planets with masses intermediate between gas giants, like Jupiter, and smaller, rockier planets, like Earth.

A survey by NASA’s Kepler space telescope mission previously showed that objects in this size range are among the most common type of planets in our Milky Way galaxy. The researchers described their… read more

We can survive killer asteroids — but it won’t be easy

April 4, 2012

(Credit: Don Davis)

More than a thousand known asteroids are classed as “potentially hazardous,” based on size and trajectory, says astronomer Neil deGrasse Tyson in Wired Science.

Currently, it looks doable to develop an early-warning and defense system that could protect the human species from impactors larger than a kilometer wide. … Smaller ones, which reflect much less light and are therefore much harder to detect at great distances, carry enough energy to incinerate entire… read more

Self-braking cars will save thousands of lives

October 8, 2012

How effective are systems that warn a driver about an impending front collision, then slam on the brakes if the driver doesn’t act quickly enough?

A lot, says a paper recently published in IEEE Transactions on Intelligent Transportation Systems, IEEE Spectrum Tech Talk reports.

Researchers at Virginia Tech’s Center for Injury Biomechanics studied systems that rely on radar to tell the car when it is coming… read more

Controlling heat like light

New approach using nanoparticle alloys allows heat to be focused or reflected just like electromagnetic waves
January 15, 2013

An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors.

The approach relies on engineered materials consisting of nanostructured semiconductor alloy crystals.

Heat is a vibration of matter — technically, a vibration of the atomic lattice of a material — just as sound… read more
