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

GOP lawmaker seeks ‘virtual Congress’ with telecommuting plan

March 25, 2013

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

SpiderFab: low-cost kilometer-scale antennas in space

“We’d like someday to be able to have a spacecraft create itself entirely from scratch, but realistically that’s quite a ways out; that’s still science fiction,” says Robert Hoyt, CEO and chief scientist of Tethers Unlimited Inc. Instead, with his “SpiderFab” project, he proposes to use 3D printing technology aboard a tiny CubeSat to create a much larger structure in space.

The  project received $100,000 from NASA’s Innovative Advanced Concepts… 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

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

Events in the future seem closer than those in the past

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

How to use mind-controlled robots in manufacturing, medicine

University at Buffalo researchers are developing brain-computer interface (BCI) devices to mentally control robots.

“The technology has practical applications that we’re only beginning to explore,” said Thenkurussi “Kesh” Kesavadas, PhD, UB professor of mechanical and aerospace engineering and director of UB’s Virtual Reality Laboratory. “For example, it could help paraplegic patients to control assistive devices, or it could help factory workers perform advanced… read more

It might be possible to restore lost memories

Memories not stored in synapses, neurobiologist finds

New UCLA research indicates that lost memories can be restored, offering hope for patients in the early stages of Alzheimer’s disease.

For decades, most neuroscientists have believed that memories are stored at the synapses — the connections between brain cells, or neurons — which are destroyed by Alzheimer’s disease. The new study provides evidence contradicting the idea that long-term memory is stored at synapses.

“Long-term memory is not… read more

Why doesn’t my phone understand me yet?

context lacking ft

Because machines can’t develop a shared understanding of the people, place and situation — often including a long social history, the key to human communication) — say University of California, Berkeley, postdoctoral fellow Arjen Stolk and his Dutch colleagues.

In other words, machines don’t consider the context of a conversation the way people do.

The word “bank,” for example, would be interpreted one way if… read more

A virus that kills cancer: the cure that’s waiting in the cold

September 5, 2012

oncolytic_virus

Professor Magnus Essand has developed a virus that may kill cancer cells, The Telegraph reports.

Cheap to produce, the virus is exquisitely precise, with only mild, flu-like side-effects in humans. But Ad5[CgA-E1A-miR122]PTD is never going to be tested to see if it might also save humans, due to lack of funding.

Brainwave training boosts brain network for cognitive control

October 25, 2012

eeg_amplitide_change_during_feedback

Researchers at  University of Western Ontario and the Lawson Health Research Institute have found that functional changes within a key brain network occur directly after a 30-minute session of noninvasive, neurofeedback training.

Background

Dysfunction of this cognitive-control network has previously been implicated in a range of brain disorders including attention deficit hyperactivity disorder, schizophrenia, depression, and post-traumatic stress disorder.

During neurofeedback, users learn to… read more

The MIT researchers who built a robotic cheetah have now trained it to see and jump over hurdles as it runs — making it the first four-legged robot to run and jump over obstacles autonomously.

The robot estimates an obstacle’s height and distance, gauges the best distance from which to jump, and adjusts… read more

New multilayer graphene structure allows ‘ultraprecise,’ ‘ultrafast’ water filtering

Next step: reduce the filter size to filter out even the smallest salts like in seawater for drinkable water -- "no longer science fiction"
February 18, 2014

graphene_water

University of Manchester researchers have taken another key step toward a seawater filter: they’ve developed one-atom-wide graphene-oxide (GO) capillaries by building multilayer GO membranes (laminates).

As described in Science, these new laminates allow for “ultraprecise” selection of molecules that can go through the filter and “ultrafast” flow of water.

The new GO filters have an “astonishingly” accurate mesh that allows them to distinguish between atomic species… read more

Self-braking cars will save thousands of lives

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

New type of molecular tag makes MRI 10,000 times more sensitive

Could detect biochemical processes in opaque tissue without requiring PET radiation or CT x-rays
March 25, 2016

Duke scientists have discovered a new class of inexpensive and long-lived molecular tags that enhance MRI signals by 10,000-fold. To activate the tags, the researchers mix them with a newly developed catalyst (center) and a special form of hydrogen (gray), converting them into long-lived magnetic resonance “lightbulbs” that might be used to track disease metabolism in real time.

Duke University researchers have discovered a new form of MRI that’s 10,000 times more sensitive and could record actual biochemical reactions, such as those involved in cancer and heart disease, and in real time.

Let’s review how MRI (magnetic resonance imaging) works: MRI takes advantage of a property called spin, which makes the nuclei in hydrogen atoms act like tiny magnets. By generating a strong… read more
