Summary of an IEEE Spectrum report

In the next few weeks, Google will start shipping its Google Glass to developers. More-polished consumer models are expected in 2014.

Details about Glass are still sketchy but here’s what we know:

  • The lightweight browband, which looks like an ordinary pair of reading glasses minus the lenses, connects to an earpiece that has much the same electronics you’d

Robot-for-hospitals

iRobot Corp., a leader in delivering robotic solutions, has announced that its RP-VITA Remote Presence Robot has received 510(k) clearance by the U.S. Food and Drug Administration (FDA) for use in hospitals. RP-VITA is the first autonomous navigation remote presence robot to receive FDA clearance.

RP-VITA is a joint effort between iRobot and InTouch Health. The robot combines the latest in autonomous navigation and mobility… read more

Self-driving cars in 2019, report says

August 23, 2012

kpmg_self_driving_cars

Autonomous cars will be in showrooms as early as 2019, or maybe even sooner, according to a report released by KPMG and the Center for Automotive Research,

The report’s authors explain that “sensor-based technologies” and “connected-vehicle communications” need to converge. Essentially, cars need to be able to communicate with other vehicles on the road so they don’t bash into each other.

They also need the ability to sense… read more

New flexible classroom design

February 8, 2013

Classroom (credit:

Researchers at North Carolina State University have developed a classroom design that gives instructors increased flexibility in how to teach their courses and improves accessibility for students, while slashing administrative costs.

The new flexible approach acknowledges the fact that students are now bringing their own laptops to class. The classrooms also include mobile infrastructure, where whiteboards, desks and tables can be reconfigured according to the… read more

‘Spin-orbitronics’ could ‘revolutionize the electronics industry’ by manipulating magnetic domains

April 14, 2015

magnetic-domain switching ft.

Researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found a new way of manipulating the walls that define magnetic domains (uniform areas in magnetic materials) and the results could one day revolutionize the electronics industry, they say.

Gong Chen and Andreas Schmid, experts in electron microscopy with Berkeley Lab’s Materials Sciences Division, led the… read more

Omega-3 improves working memory in healthy young adults

October 31, 2012

Lovaza

Researchers at the University of Pittsburgh have determined that healthy young adults ages 18–25 can improve their working memory by increasing their Omega-3 fatty acid intake.

Before they began taking the supplements, all participants were asked to perform a working memory test in which they were shown a series of letters and numbers. The young adults had to keep track of what appeared one, two,… read more

When machines do your job

Researcher Andrew McAfee says advances in computing and artificial intelligence could create a more unequal society

Are American workers losing their jobs to machines?

That was the question posed by Race Against the Machine, an influential e-book published last October by MIT business school researchers Erik Brynjolfsson and Andrew McAfee.

The pair looked at troubling U.S. employment numbers — which have declined since the recession of 2008-2009 even as economic output has risen — and concluded that computer technology was… read more

Driverless vehicles to zip at full speed through intersections

December 6, 2012

intersection

Driverless vehicles will safely wiz through intersections at the full speed limit, according to researchers from Virginia Tech Transportation Research.

Autonomous vehicles will turn themselves over to an automated intersection controller, with the controller tweaking their trajectory to prevent crashes, explained Ismail Zohdy of Cairo, Egypt, a Ph.D. student in civil engineering at Virginia Tech, and Hesham Rakha, director of the Center for Sustainableread more

Academic researchers and scientists at companies like Microsoft, IBM, and Hewlett-Packard have been working to develop quantum computers.

Now, Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to… read more

Physicists solve uncertainty about uncertainty principle

September 10, 2012

uncertainty-12_09_07

The Heisenberg uncertainty principle is one of the cornerstones of quantum mechanics: it’s impossible to measure anything without disturbing it.

For instance, any attempt to measure a particle’s position must change its momentum.

But never mind all that. It’s wrong, University of Toronto physicists say they have just proven.

(This has important implications for quantum information and especially quantum cryptography, where it is fundamental to the security of certain protocols.)… read more

Planets could orbit singularities inside black holes

November 10, 2011

Black hole orbit

Certain black holes can have a complex internal structure that could allow photons, particles, and perhaps even planets to orbit the central singularity without ever getting sucked all the way in, Technology Review Physics arXiv Blog reports.

“Advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei without being visible from the outside,” says Vyacheslav Dokuchaev, Institute for Nuclear Research of the Russian… read more

Taking 3D printing into the metal age

October 16, 2013

mars_probe_3d_printed

The European Space Agency (ESA)and the EU, together with industrial and educational partners, are developing the first large-scale production methods to 3D-print complex 3D-printed parts made of metal that can withstand temperatures at 1000°C — fit for space and the most demanding applications on Earth.

3D printers are expected to revolutionize the way we live but until recently they could work with only plastic, which… read more

Five potential habitable exoplanets now

Exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet
July 25, 2012

Gliese 581g

New data suggests the exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet. The nearby star Gliese 581 — located about 20 light years away from Earth in the constellation Libra — has four planets; the outermost planet, Gliese 581d, was already suspected habitable.

This will be the first evidence for any two potential habitable exoplanets that are orbiting the same star.

Based on… read more

Google DeepMind’s machine-learning AlphaGo program has defeated South Korean Go champion Lee Sedol in the first match of five historic matches between human and AI, taking place in Seoul.

The second round will take place today (Wednesday March 9 in U.S.) at 11 PM ET (1 PM KST), also covered on YouTube.

Last October, AlphaGo defeated European Go champion Fan Hui 5-0, making it the first… read more

Could robots become ‘aware’ of their own limitations?

April 3, 2013

(credit: Allegra Boverman and Christine Daniloff/MIT)

MIT researchers have developed software for robots that enables them to be more “aware” of their own limitations, such as knowing the whereabouts of an object, or its own location within a room.

Most successful robots today tend to be used either in fixed, carefully controlled environments, such as manufacturing plants, or for performing fairly simple tasks such as vacuuming a room,

But carrying out complicated sequences… read more
