If you’re on the edge about deciding to get a 3D printer, this Kickstarter campaign for The Micro, billed as the “first truly consumer 3D printer,” may just push you off it.

It already has for more than 9,000 backers, who have pledged an impressive $2.7 million since April 7 — far exceeding the $50,000 goal.

For a pledge of $299, you get the pre-assembled printer… read more

How telecom convergence may widen the digital divide

Technology is helping communication companies merge telephone, television and Internet services, but a push to deregulate may leave some customers on the wrong side of the digital divide during this convergence, according to a Penn State telecommunications researcher.

“Moving away from copper lines is an example of abandoning obsolete technology and embracing technology that is faster, better, cheaper and more convenient,” said Rob Frieden, Pioneers Chair in… read more

Light from self-luminous tablet computers can affect evening melatonin, delaying sleep

New research can aid in the development of “circadian-friendly” electronic devices
August 29, 2012

Exposure to electronic devices with self-luminous displays causes melatonin suppression, which might lead to delayed bedtimes, especially in teens, a Lighting Research Center (LRC) at Rensselaer Polytechnic Institute study has found.

The study showed that a two-hour exposure to light from self-luminous electronic displays can suppress melatonin by about 22 percent.

Stimulating the human circadian system to this level may affect sleep in those using the devices prior to… read more

Transhuman week: exploring the frontiers of human enhancement

September 5, 2012

Ekso exoskeleton

Wired U.K.‘s Transhuman Week seeks to navigate transhumanist issues through a series of features, galleries and expert guest posts from September 3 to 7.

Transhumanism explores the application of technology and science to enhance human bodies and minds regardless of whether they are perceived to have any disabilities, and extending human life. It  may include low-level biohacking, physical augmentation, performance-enhancing drugs and even genetic modification.

World’s most human-like android head

April 26, 2013

GF2045

Dr. Dmitry Itskov, founder of the 2045 Initiative and Global Future 2045 congress (GF2045), announced Thursday that he will unveil Dr. David Hanson’s latest android, the Dmitry Avatar-A head — the “world’s most human-like android head” — at the GF2045 congress, scheduled for June 15–16 at Lincoln Center in New York City.

The new android, a robotic replica of Itskov’s head, is being created by… read more

Researchers prove that memories reside in specific brain cells

March 23, 2012

Mouse Hippocampus

In a new MIT study, researchers used optogenetics to show that memories reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie.

“We demonstrate that behavior based on high-level cognition, such as the expression of a specific memory, can… read more

Could synthetic fuels eliminate entire US need for crude oil, create ‘new economy’?

Baliban, and Christodoulos A. Floudas/Princeton University)

The U.S. could eliminate the need for crude oil by using a combination of coal, natural gas, and non-food crops to make synthetic fuel, a team of Princeton researchers has found.

Besides economic and national security benefits, the plan has potential environmental advantages. Because plants absorb carbon dioxide to grow, the United States could cut vehicle greenhouse emissions by as much as 50 percent in… read more

Scientists and bankers — a new model army

April 12, 2012

Bankers must surrender more information on their activities to scientists to use it to build better system-wide financial models, says John Liechty, director of the Center for the Study of Global Financial Stability and Professor of Marketing and Statistics at Pennsylvania State University in University Park.

Existing financial models failed to predict the crisis of 2008 and the follow-on crisis of 2011–12. They missed the huge system-wide risks that… read more

Eureka! When a blow to the head creates a sudden genius

May 20, 2012

Stephen Wiltshire

How can we explain “acquired savants” — people with extraordinary talent who’ve miraculously developed artistic, musical, or mathematical abilities as a result of a brain injury, or temporarily from a transcranial magnetic stimulation (TMS) session — since they weren’t born with the talent and didn’t learn it later?

For example, how is it that somebody like Derek Amato (video below), who’d never demonstrated any musical talent before hitting his head at the… read more

We’re all living longer, but longevity increases not benefitting everybody

December 21, 2012

Life_expectancy

Global lifespans have risen dramatically in the past 40 years, but the increased life expectancy is not benefitting body equally, say University of Toronto researchers. In particular, adult males from low- and middle-income countries are losing ground.

People are living longer on average than they were in 1970, and those extra years of life are being achieved at lower cost, the researchers, led by U of… read more

Leap 3D out-Kinects Kinect

May 22, 2012

leap_motion

Leap Motion is unveiling its Leap 3D motion control system, Technology Review Hello World reports.

Leap Motion appears to outrank Kinect in terms of its capability. The technology, reports CNET, can detect motion with up to a hundredth of a millimeter accuracy; it’s nuanced enough to detect fingers, for instance, enabling the possibility of touch-free pinch-to-zoom.

When the device is available for commercial release,… read more

Low-cost design makes ultrasound imaging affordable to the world

September 17, 2012

ultrasound-fetus

An ultra-low cost scanner that can be plugged into any computer to show images of an unborn baby has been developed by Newcastle University engineers.

The handheld USB device — roughly the size of a computer mouse — works like existing ultrasound scanners, using pulses of high frequency sound to build up a picture of the unborn child on the computer screen.

However, unlike the… read more

NASA investigates use of graphene for new sensors

December 7, 2012

Graphene

NASA researchers have developed graphene-based sensors to detect trace elements in Earth’s upper atmosphere and structural flaws in spacecraft.

Technologist Mahmooda Sultana at NASA’s Goddard Space Flight Center is investigating nano-sized detectors that could detect atomic oxygen and other trace elements in the upper atmosphere and structural strains in everything from airplane wings to spacecraft buses.

“The cool thing about graphene is its properties,”… read more

Why glial cells should be included in the BRAIN initative

Glia, the non-neuronal cells that make up most of the brain, must not be left out of the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative, says R. Douglas Fields, chief of the Nervous System Development and Plasticity Section at NIH, in Nature News.

“A major stumbling block is the project’s failure to consider that although the human brain contains roughly 100 billion neurons, it… read more

Brain frontal lobes not sole center of human intelligence

May 15, 2013

brain_lobes

The frontal lobes in humans vs. other species are not — as previously thought — disproportionately enlarged relative to other areas of the brain, according to a study by Durham and Reading universities.

It concludes that the size of our frontal lobes — an area in the brain of mammals located at the front of each cerebral hemisphere — cannot solely account for humans’ superior cognitive… read more
