Smell-o-Vision is finally here

April 1, 2013

smelling_screen

Smell-O-Vision was a system that released odors during the projection of a film so that the viewer could “smell” what was happening in the movie.

Now the “smelling screen,” invented by Haruka Matsukura at Tokyo University of Agriculture and Technology in Japan and colleagues, makes smells appear to come from the exact spot on any LCD screen that is displaying the image of a cup of coffee,… read more

Space elevator by 2050 planned, to include space solar power

February 22, 2012

space_elevator

Obayashi Corp., headquartered in Tokyo, has unveiled a project to build a space elevator by the year 2050 that would transport passengers to a station 36,000 kilometers above the Earth and transmit power to the ground.

A cable, made of carbon nanotubes, would be stretched up to 96,000 kilometers, or about one-fourth of the distance between the Earth and the moon. One end of… read more

Can anyone catch Khan Academy? The fate of the U in the YouTube era

July 23, 2012

salman_khan

Traditional American universities are suddenly running scared of YouTube, Xconomy reports, along with Vimeo, 5min, iTunes U, TED and the Internet Archive.

Without YouTube, Sal Khan and Khan Academy could never have reached his 4 million unique viewers a month with their 3,200 videos, viewed 170 million times.

Internet video sharing technology means that talented people from outside the education establishment can make and publish free educational videos that are… read more

Toward achieving 1 million times increase in computing efficiency

July 11, 2012

Magnetoresistive spin-transistor

Northwestern University researchers may have found an alternative to CMOS (current computer processor chips) that would allow for highly efficient computer logic circuits that generate much less heat: an entirely new logic circuit family based on magnetic semiconductor devices that could lead to logic circuits up to 1 million times more power-efficient than today’s.

Background

Modern-day computers are based on logic circuits using semiconductor transistors.… read more

Hands-on with the next generation Kinect: PrimeSense Capri

January 17, 2013

capri_21358236815775

The next generation of PrimeSense‘s 3D sensor (used inside the Microsoft Kinect), called Capri, will revolutionize vision for very cheap and very expensive robots, IEEE Spectrum reports.

Capri is also small enough that it’ll be able to fit into tablets (and eventually smartphones).

The first engineering samples of Capri are expected to ship in 2-3 months, with consumer kits… read more

Handheld plasma flashlight rids skin of pathogens

April 6, 2012

portableplasmaflashlight

Imagine a handheld, battery-powered plasma-producing device that can rid skin of bacteria in an instant — no soap and water required.

It could be used in ambulance emergency calls, natural disaster sites, military combat operations, and wherever treatment is required in remote locations.

It’s called a “plasma flashlight.”

In an experiment, the plasma flashlight effectively inactivated a thick biofilm with 17 different layers of one of the most… read more

Virus caught in the act of infecting a cell

January 11, 2013

virus_injecting

The detailed changes in the structure of a virus as it infects an E. coli bacterium have been observed for the first time.

To infect a cell, a virus must be able to first find a suitable cell and then eject its genetic material into its host.

This robot-like process has been observed in a virus called T7 and visualized by Ianread more

A 3D-printed navy?

Instead a carrying spare parts, space-constrained U.S. Navy ships in the future might carry 3-D printers and bags of various powdered ingredients, and simply download the design files needed to print items as necessary, according to the Armed Forces Journal,

“Perhaps closer at hand is a distributed global production network in which sailors and Marines send an email with a digital scan or design for a

Imaging global brain connectivity can predict how intelligent you are

'Global brain connectivity' with a part of the left lateral prefrontal cortex explains 10 percent of variance in individual intelligence
August 2, 2012

wustl_neural_connections

What factors distinguish the brains of exceptionally smart humans from those of average humans?

Overall brain size matters somewhat, accounting for about 6.7 percent of individual variation in intelligence.

More recent research has pinpointed the brain’s lateral prefrontal cortex, a region just behind the temple, as a critical hub for high-level mental processing, with activity levels there predicting another 5 percent of variation in individual intelligence.… read more

Self-assembled nanoparticles release chemotherapy drug and heat to treat cancer

October 21, 2012

gold nanorods

In new research from Brigham and Women’s Hospital (BWH), researchers have invented self-assembled, multifunctional, near-infrared-light-responsive nanoparticles to treat cancer.

The nanoparticles can deliver a chemotherapy drug specifically targeted to cancer cells and selectively release the drug in response to an external beam of light. They can also create heat for synergistic thermo-chemo-mediated anti-tumor effects.

Excitement around the potential for targeted nanoparticles (NPs) that can be controlled… read more

Linden Lab intends to integrate the Oculus Rift virtual-reality headset with Second Life, Wagner James Au reports on New World Notes.

“The Oculus could become Second Life’s killer app, but only if Linden Lab is willing to go all in,” said Au. “Sounds like they are doing just that, in an official capacity.

We’ll get to experience Second… read more

New metamaterial lens focuses radio waves

Device could improve satellite and molecular imaging
November 15, 2012

The orientation of 4,000 S-shaped units forms a metamaterial lens that focuses radio waves with extreme precision, and very little energy lost (credit: Dylan Erb/MIT)

MIT researchers have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision.

The concave lens exhibits a property called negative refraction, bending electromagnetic waves — in this case, radio waves — in exactly the opposite sense from which a normal concave lens would work.

Concave lenses typically radiate radio waves… read more

Faster-than-light neutrino puzzle claimed solved by special relativity

The relativistic motion of clocks on board GPS satellites exactly accounts for the superluminal effect in the OPERA experiment, says  physicist Ronald van Elburg at the University of Groningen in the Netherlands, The Physics arXiv Blog reports.

“From the perspective of the clock, the detector is moving towards the source and consequently the distance travelled by the particles as observed from the clock is shorter,”… read more

Germany to tap brakes on high-speed trading

October 29, 2012

hft_chart

Germany is set to advance a bill Wednesday imposing a spate of new rules on high-frequency trading, escalating Europe’s sweeping response to concerns that speedy traders have brought instability to the markets.

The measure seeks to require traders to register with Germany’s Federal Financial Supervisory Authority, collect fees from those who use high-speed trading systems excessively, and force stock markets to install circuit breakers that can interrupt trading if… read more
