Pupil dilation reveals sexual orientation in new Cornell study

August 7, 2012

Blue Eye Macro

There is a popular belief that sexual orientation can be revealed by one’s pupil dilation when viewing attractive people, but there has been no scientific evidence.

Now Cornell University researchers have confirmed it in an experiment, using a specialized infrared lens to measure pupillary changes in participants watching erotic videos.

Pupils widened most to videos of people who participants found attractive, thereby revealing where they were on… read more

Tito and a group of coauthors from NASA and several aerospace companies… read more

Space-based solar farms power up

February 28, 2013

spsalpha-concept

Space-based solar power (SBSP) has once again begun to attract attention with projects emerging in the US, Russia, China, India and Japan, among others. All are driven by increasing energy demands, soaring oil and gas prices, a desire to find clean alternatives to fossil fuels and by a burgeoning commercial space industry that promises to lower the cost of entry into space and spur on a host of new industries,… read more

Limb regeneration: do salamanders hold the key?

June 24, 2014

Salamander (credit: UCL)

The secret of how salamanders successfully regrow body parts is being unravelled by University College London (UCL) researchers in a bid to apply it to humans.

For the first time, researchers have found that the “ERK pathway” must be constantly active for salamander cells to be reprogrammed, and hence able to contribute to the regeneration of different body parts.

The team identified a key… read more

MINIATURE SURVEILLANCE HELICOPTERS HELP PROTECT FRONTLINE TROOPS

A tiny remote-control helicopter is being used for surveillance on the front line to detect enemy threats to British troops.

British troops are using a nano drone just 10cm long and weighing 16 grams on the front line in Afghanistan to provide vital information on the ground, Sky News reports.

They are the first to use the state-of-the-art handheld tiny surveillance helicopters, which relay reliable full… 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

How Obama was dangerously naive about STUXNET and cyberwarfare

Stuxnet

A Times exposé suggests that the White House failed to consider how our own cyberweapons would be used against us, Technology Review Mims’s Bits reports.

If the New York Timescomprehensive account of the birth of the STUXNET worm that slowed Iran’s efforts to enrich uranium tells us anything, it’s that the Obama administration was remarkably naive about the potential for the proliferation of the… read more

Wireless device converts ‘lost’ microwave energy into electric power

November 8, 2013

Power harvesting split-ring resonator

Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University’s Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels.

The device wirelessly converts a microwave signal to direct current voltage that is capable of recharging a cell phone battery or other small electronic device.

It operates on a principle similar to… 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
