A robot as cheap, easy-to-use, and safe as an iPhone

August 26, 2012

Rethink Robotics’ goal is that its [forthcoming] cheap, easy-to-use, safe robot will be to industrial robots what the personal computer was to the mainframe computer, or the iPhone was to the traditional phone, says The New York Times writer Thomas L. Friedman.

“That is, it will bring robots to the small business and even home and enable people to write apps for them the way they do with PCs… read more

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published in an open-access paper in Monthly Notices of the Royal Astronomical Society.

For more than 30 years, scientists have argued about a controversial hypothesis relating to periodic mass extinctions and impact craters — caused by comet and asteroid showers — on Earth.

The European Commission has selected the two research proposals it will fund to the tune of half-a-billion euros ($650 million U.S.) each, after a two-year, high-profile contest, Nature News reports.

The Human Brain Project, led by neuroscientist Henry Markram at the Swiss Federal Institute of Technology (EPFL) in Lausanne, plans to simulate the human brain in a supercomputer. (See “Brain inread more

Can an algorithm write a better news story than a human reporter?

April 8, 2013

narrative-science

Every 30 seconds or so, an algorithm developed by Narrative Science produces a computer-written news story, Wired reports.

The articles run on the websites of respected publishers like Forbes, as well as other Internet media powers (many of which are keeping their identities private).

Niche news services hire Narrative Science to write updates for their subscribers, be they sports fans, small-cap investors, or fast-food… read more

IBM launches functioning brain-inspired chip

Operates at 46 billion “synaptic operations” per second per watt; 100 trillion "synapses" planned, matching the approximate number in the human brain

IBM announced today, August 7, the first computer chip to achieve one million programmable “neurons,” 256 million programmable “synapses,” and 46 billion “synaptic operations” per second per watt — simulating the function of neurons and synapses in the brain.*

Neurosynaptic. At 5.4 billion transistors, this low-power, production-scale “neurosynaptic” (brain-inspired) chip (the size of a postage stamp), is one of the largest CMOS chips ever built, IBM says.… read more

Travelers to Mars risk leukemia cancer, weakened immune function from radiation, NASA-funded study finds

March 27, 2017

Radiation encountered in deep space travel may increase the risk of leukemia cancer in humans traveling to Mars, NASA-funded researchers at the Wake Forest Institute for Regenerative Medicine and colleagues have found, using mice transplanted with human stem cells.

“Our results are troubling because they show radiation exposure could potentially increase the risk of leukemia,” said Christopher Porada, Ph.D., associate professor of regenerative medicine and… read more

Future Day: a new global holiday March 1

February 29, 2012

future_day

Why are nearly all our holidays focused on celebrating the past, or the cyclical processes of nature? Why not celebrate the amazing future we are collectively creating?

That’s the concept behind a new global holiday, Future Day (March 1), conceived by AI researcher Dr. Ben Goertzel.

Future Day 2012 gatherings are scheduled in more than a dozen cities, as well as in… read more

Libratus, an AI developed by Carnegie Mellon University, has defeated four of the world’s best professional poker players in a marathon 120,000 hands of Heads-up, No-Limit Texas Hold’em poker played over 20 days, CMU announced today (Jan. 31) — joining Deep Blue (for chess), Watson, and Alpha Go as major milestones in AI.

Libratus led the pros by a collective $1,766,250 in chips.* The tournament was held… read more

Internet activists on red alert ahead of United Nations conference

How the ITU could put the Internet behind closed doors

“After experiencing drastic changes in my environment, I looked for other experiences that might profoundly affect my perception of the self. So I devised another experiment where everyday I took a different drug and drew myself under the influence.

“Within weeks I became lethargic and suffered mild brain damage. I am still conducting this experiment but over greater lapses of time.  I only take drugs that are given… read more

Stem cells, embryo research and synthetic biology are just a few of the issues that will force strange new political alliances, University of Pennsylvania bioethicist Jonathan D. Moreno writes in New Scientist.

The new biology, or biotechnology — including stem cells, embryo research, synthetic biology and reproductive technology — has unprecedented power to change basic life processes.

One recent example is the controversy over the “three-parent… read more

A thin, flexible electrode developed at the University of Michigan is 10 times smaller than the nearest competition and could make long-term measurements of neural activity practical.

This kind of technology could also be used eventually to send brain-computer-interface (BCI) signals to prosthetic limbs, overcoming inflammation caused by larger electrodes, resulting in damage to both the brain and the electrodes.

Existing electrodes are stiff and enormous… read more
