Rice unveils super-efficient solar-energy technology

November 21, 2012

The solar steam device developed at Rice University has an overall energy efficiency of 24 percent, far surpassing that of photovoltaic solar panels. It may first be used in sanitation and water-purification applications in the developing world. (Credit: Jeff Fitlow/Rice University)

Rice University scientists have unveiled a revolutionary new technology that uses silicon dioxide/gold nanoshells and N115 carbon nanoparticles to convert solar energy directly into steam. The new “solar steam” method from Rice’s Laboratory for Nanophotonics (LANP) is so effective it can even produce steam from icy cold water.

The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels, by comparison, typically have… read more

Is faster-than-light travel possible?

July 23, 2013

Alcubierre warp drive

Engineers at NASA Johnson Space Center are designing instruments to find out, by slightly warping the trajectory of a photon and measuring the distance it travels, The New York Times reports.

Inspiration for the research came from Mexican physicist Miguel Alcubierre, who proposed in 1994 a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to… read more

Scientists at IBM and Repsol SA, Spain largest energy company, announced today (Oct. 30) the world’s first research collaboration using cognitive technologies like IBM’s Watson to jointly develop and apply new tools to make it cheaper and easier to find new oil fields.

An engineer will typically have to manually read through an enormous set of journal papers and baseline reports with models of reservoir, well, facilities, production, export,… read more

Are you in pain, but your doc won’t increase your hydrocodone dosage (or you don’t want to overdose)?

University of Texas at Arlington researchers may have a (future) drug-free fix: electrical stimulation of a deep middle-brain structure that blocks pain signals at the spinal cord level while triggering release of pleasure-associated dopamine to reduce the associated emotional distress.

“This is the first study to use a… read more

Will the elderly ever accept care from robots?

The new movie Robot & Frank shows a machine taking care of an old man. The challenge here isn’t the technology, but the people.
August 18, 2012

ROBOT&FRANK

Set in the near future, Frank, a retired cat burglar, has two grown kids who are concerned he can no longer live alone. They are tempted to place him in a nursing home until Frank’s son chooses a different option: against the old man’s wishes, he buys Frank a walking, talking humanoid robot programmed to improve his physical and mental health.

The music of the silks

Researchers synthesize a new kind of silk fiber --- and find that music can help fine-tune the material’s properties
November 30, 2012

This diagram of the molecular structure of one of the artificially produced versions of spider silk depicts one that turned out to form strong, well-linked fibers. A different structure, made using a variation of the same methods, was not able to form into the long fibers needed to make it useful. Musical compositions based on the two structures helped to show how they differed. (Credit: Markus Buehler/MIT)

Research by MIT’s Markus Buehler — together with David Kaplan of Tufts University and Joyce Wong of Boston University — has synthesized new variants on silk’s natural structure, and found a method for making further improvements in the synthetic material.

The work stems from a collaboration of civil and environmental engineers, mathematicians, biomedical engineers and musical composers. The results are reported in a paper published… read more

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

August 26, 2012

rethink_robotics

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

New cosmic background radiation map challenges some foundations of cosmology

March 22, 2013

Planck_CMB_large

The most detailed map ever created of the cosmic microwave background — the relic radiation from the Big Bang — acquired by ESA’s Planck space telescope, has been released, revealing features that challenge the foundations of our current understanding of the Universe and may require new physics.

  • The fluctuations in the CMB temperatures at large angular scales do not match those predicted by the

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

The Future of Life Institute (FLI) announced today (July 1) the selection of 37 research teams around the world to which it plans to award about $7 million from Elon Musk and the Open Philanthropy Project for a global research program aimed at keeping AI beneficial to humanity.

The grants were funded by part of Musk’s $10 million donation to the group in January and $1.2 million from the… 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

Crewed missions to Mars such as Mars One may face dangerous levels of cosmic rays (energetic particles), according to a new paper in the journal Space Weather by University of New Hampshire (UNH) scientists.

This is due to a recent highly abnormal and extended lack of solar activity, resulting in extremely low densities and magnetic field strengths in the solar wind.

This results in a serious reduction in the… read more

“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
