“It’s not humanly possible to practice the best possible medicine. We need machines,” said Herbert Chase, a professor of clinical medicine at Columbia University and member of IBM’s Watson Healthcare Advisory Board, Wired Science reports.

“A machine like [IBM's Watson], with massively parallel processing, is like 500,000 of me sitting at Google and Pubmed, trying to find the right information.”

Yet though Watson is clearly a powerful tool,… read more

Human v 2.0: Ray Kurzweil vs. Hugo de Garis

October 24, 2006

“Meet the scientific prophets who claim we are on the verge of creating a new type of human – a human v2.0.

“It’s predicted that by 2029 computer intelligence will equal the power of the human brain. Some believe this will revolutionise humanity – we will be able to download our minds to computers extending our lives indefinitely. Others fear this will lead to oblivion by giving rise to… read more

Amazon.com Inc. is developing a high-end smartphone featuring a screen that allows for three-dimensional images without glasses, The Wall Street Journal reports.

Using retina-tracking technology, images on the smartphone would seem to float above the screen like a hologram and appear three-dimensional at all angles, and users may be able to navigate through content using just their eyes, according to sources,

With smartphones, Amazon could collect new… read more

DARPA‘s Warrior Web program seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for soldiers, who often carry 100-pound loads for extended periods over rough terrain.

DARPA envisions Warrior Web augmenting the work of soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness — all while using no more than 100W of power.… read more

Boston Dynamics’ new running robot: WildCat

October 6, 2013

WildCat2

Boston Dynamics has unleashed Cheetah as “WildCat” — a four-legged robot being developed to run fast on all types of terrain.

So far, WildCat has run at about 16 mph on flat terrain using bounding and galloping gaits — still slower than tethered Cheetah, with a top speed of 28.3 mph. Boston Dynamics is developing WildCat with funding from DARPA’s M3 program. (To… read more

How unconscious processing improves decision-making

February 15, 2013

New brain imaging research from Carnegie Mellon University provides some of the first evidence showing how the brain unconsciously processes decision information in ways that lead to improved decision making. Published in the journal Social Cognitive and Affective Neuroscience, the study found that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task.

Fullerene C60 administration doubles rat lifespan with no toxicity

April 17, 2012

Optical microscopy of spleen sections (a) oral and (b) i.p. treatment with olive oil only; (c) oral and (d) i.p. treatment with C60-olive oil. The arrows indicate C60 crystalscontaining macrophages with specific brown color. (Credit:

Researchers at the University of Paris and colleagues fed the molecule fullerene (C60 or “buckyballs”) dissolved in olive oil to rats and found it almost doubles their lifespan, with no chronic toxicity.

The results suggest that the effect of C60, an antioxidant, on lifespan is mainly due to the attenuation of age-associated increases in oxidative stress, according to the researchers.

Pharmacokinetic studies show that dissolved C60 is absorbed by the gastro-intestinal tract and… read more

A weapon we can’t control

Stuxnet

The decision by the United States and Israel to develop and then deploy the Stuxnet computer worm against an Iranian nuclear facility late in George W. Bush’s presidency marked a significant and dangerous turning point in the gradual militarization of the Internet, says Misha Glenny, a visiting professor at the Columbia University School of International and Public Affairs, and the author of DarkMarket: Cyberthieves, Cybercopsread more

What happens during the brain’s ‘resting state’?

September 20, 2012

fMRI images

Over the past few years, some researchers have been adding a bit of down time to their study protocols, Nature News reports. While subjects are still lying in the functional magnetic resonance imaging (fMRI) scanners, the researchers ask them to try to empty their minds. The aim is to find out what happens when the brain simply idles. And the answer is: quite a lot.

Some circuits… read more

Piggy-backing proteins ride white blood cells to destroy metastasizing cancer

“Unnatural killer cells" zap circulating tumor cells in the bloodstream
January 8, 2014

nanoscale_liposomes_trail

Cornell biomedical engineers have discovered a new way to destroy metastasizing cancer cells traveling through the bloodstream by hitching cancer-killing proteins along for a ride on life-saving white blood cells.

“These circulating cancer cells are doomed,” said Michael King, Cornell professor of biomedical engineering and the study’s senior author.

“About 90 percent of cancer deaths are related to metastases, but now we’ve found a way to… read more

How easy would it be to monitor the movement of everyone on the street by a private citizen with a few hundred dollars to spare?

Brendan O’Connor, 27, bought some plastic boxes and stuffed them with a $25, credit-card size Raspberry Pi Model A computer and a few over-the-counter sensors, including Wi-Fi adapters, The New York Times reports.

He connected each of those boxes to a… read more

Unexplained communication between brain hemispheres without corpus callosum

October 21, 2011

Ag CC

Could the brain be using electromagnetic fields to communicate between hemispheres — the electromagnetic field theory of consciousness proposed by Johnjoe McFadden (School of Biomedical and Life Sciences, University of Surrey)?

Neuroscientists at the California Institute of Technology (Caltech) have made a puzzling finding: people born without a corpus callosum (which links the two hemispheres of the brain)  — a condition called agenesis… read more

The invention of the motion picture enabled visual storytelling and at a mass scale unimaginable before.

The equivalent to that moment is happening right now with the advent of wearable computing. These wearable technologies like Google’s glasses that project information right where a person is looking will have the same effect on smartphones and computers as… read more
