Asteroid deflection mission seeks smashing ideas

January 16, 2013

AIDA_mission_concept_node_full_image

A space rock several hundred meters across is heading towards our planet and the last-ditch attempt to avert a disaster — an untested mission to deflect it — fails.

This fictional scene of films and novels could well be a reality one day. So the European Space Agency (ESA) is appealing for research ideas to help guide the development of a U.S.-European asteroid deflection mission… read more

Human-Race

The Human Race to the Future: What Could Happen — and What to Do, by Dr. Daniel Berleant (388 pages), the first book published by the Lifeboat Foundation, is available free (Kindle version) to KurzweilAI readers on July 8 as a one-day promo.

A non-fiction book verging on science fiction, its imaginative future scenarios include colonizing the planet Mercury (it has water at the poles), GPS-enabled… read more

Beam yourself to work in a remote-controlled body

September 26, 2012

beam-robot

To make it more practical for engineers and others living in cheaper places to telecommute to work, Suitable Technologies (a Willow Garage spinoff) has developed a roving telepresence system that is more practical and less awkward to use than previous systems, says founder Scott Hassan, Technology Review reports.

The $16,000 Beam Remote Presence telepresence system, now available, can save on the expense and time of long-haul travel and allows remote workers to be… read more

Breakthrough: compound generated by low carb/low-calorie diet blocks effects of aging

Discovery suggests way to protect cells from damage caused by oxidative stress
December 10, 2012

salad

Scientists at the Gladstone Institutes have identified a novel mechanism by which a type of low-carb, low-calorie diet — called a “ketogenic diet” — could delay the effects of aging: the compound  β-hydroxybutyrate (βOHB), a “ketone body” that is generated during a prolonged low-calorie or ketogenic diet.

Blocking oxidative stress

While ketone bodies such as βOHB can be toxic when… read more

Harnessing the energy of 2,000 suns

April 29, 2013

HCPVT

The Swiss Commission for Technology and Innovation has awarded scientists a $2.4 million (2.25 million CHF) grant to develop an affordable photovoltaic system capable of concentrating solar radiation 2,000 times and converting 80 percent of the incoming radiation into useful energy.*

The system would also provide desalinated water and cool air in sunny, remote locations where they are often in short supply.

The prototype HCPVT system… read more

Stay cool and live longer?

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms (nematodes) in cold environments — and this genetic program also exists in warm-blooded animals, including humans.

“This raises the intriguing possibility that exposure to cold air — or pharmacological stimulation of the cold-sensitive genetic program — may promote longevity in mammals,” said… read more

Obama to unveil specifics of Brain Activity Map project

April 2, 2013

President Obama on Tuesday will announce specifics on the Brain Activity Map project Tuesday, The New York Times reports. The initiative, which will officially be known as Brain Research Through Advancing Innovative Neurotechnologies, or Brain for short, has been designated a grand challenge of the 21st century by the Obama administration.

The broad new research initiative, starting with $100 million in 2014, is intended to invent and… read more

Where is imagination located in the human brain?

September 18, 2013

Schlegel-mental-workspace-image-high-res.jpg

Imagination lies in a widespread neural network — the brain’s “mental workspace” — that consciously manipulates images, symbols, ideas and theories and gives humans the laser-like mental focus needed to solve complex problems and come up with new ideas, Dartmouth researchers conclude in a new study.

“Our findings move us closer to understanding how the organization of our brains sets us apart from other species and provides… read more

Cosmic radiation — which would bombard astronauts on deep space missions to places like Mars — could accelerate the onset of Alzheimer’s disease, a new study in the open-access journal PLOS ONE shows.

“Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and… read more

A 3D-printing pen

February 25, 2013

3doodler

Have you ever wished you could just draw a object in the air and have it magically printed out? 

WoobbleWorks has created 3Doodler (a Kickstarter project), the world’s first “3D printing pen” to do just that.

As you draw, it extrudes ABS plastic (the material used by many 3D printers) in the air or on surfaces — no software or computers required.

The… read more

Rollable, foldable e-devices coming

What if a tablet screen were a paper-thin plastic that rolled like a window shade?

University of Cincinnati researchers have now announced experiment verification that such “electrofluidic imaging film” works. The breakthrough is a white, porous film coated with a thin layer of reflective electrodes and spacers that are then subjected to unique and sophisticated fluid mechanics in order to electrically transport the colored ink and clear-oil… read more

Well-connected hemispheres of Einstein’s brain may have contributed to his brilliance

The left and right hemispheres of Albert Einstein’s brain were unusually well connected to each other and this may have contributed to his brilliance, according to a new study [1], the first to detail Einstein’s corpus callosum.

The corpus callosum is the brain’s largest bundle of fibers that connects the two cerebral hemispheres and facilitates interhemispheric communication.

The study was published in the journal Brain. Lead… read more

3D printed car is as strong as steel, half the weight, and nearing production

Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles.

If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced, Wired reports. His creation is called the Urbee 2 and it could revolutionize parts manufacturing while creating… read more

Google Glass: how it works (infographic)

German artist Martin Missfeldt has created an infographic that attempts to show how Google Glass works, based on various sources (listed below). One correction: an image is actually not projected directly onto the retina; it is refracted by the cornea and focused by the lens.

Google’s smart contact lens project could allow diabetics to track glucose levels automatically

January 17, 2014

To help people with diabetes as they try to keep their blood sugar levels under control, Google is testing a smart contact lens designed to measure glucose levels in tears.

It uses a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material, according to Google Official Blog.

People with diabetes must still prick their finger and test… read more
