Vices like pornography and gambling continue to be a significant factor in the currency’s value.
But other new uses for the currency continue to pop up. Coinbase, a startup aiming to… read more
A cheap, emissions-free device that uses a 1.5-volt AAA battery to split water into hydrogen and oxygen by electrolysis has been developed by scientists at Stanford University.
Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive, abundant nickel and iron.
“This is the first time anyone has used non-precious metal catalysts to split water at a voltage… read more
Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first electronic structure observations of the adsorption of carbon dioxide inside a metal-organic framework (MOF).
The “Mg-MOF-74″ MOF’s porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants.
MOFs are molecular systems consisting of a metal oxide center surrounded by organic… read more
IBM today (Nov. 14) announced that the U.S. Department of Energy has awarded IBM contracts valued at $325 million to develop and deliver “the world’s most advanced ‘data-centric’ supercomputing systems” at Lawrence Livermore and Oak Ridge National Laboratories to advance innovation and discovery in science, engineering and national security.”
The researchers’ new imaging technique, based on the detection of calcium ions in neurons, could help them map the brain circuits that perform such functions.
It could also provide new insights into the… read more
A video shows a woman carrying a box into a building. Later, it shows her leaving the building without it. What was she doing?
Carnegie Mellon University’s (CMU) Mind’s Eye program is creating intelligent software that will recognize human activities in video and predict what might happen next. It will also flag unusual events and deduce actions that may be occurring off-camera.
Automating the time-consuming job of… read more
As the action moves to tablets, mobile devices, and the cloud, what’s the future for the desktop PC?
Dim, according to OnLive, Inc., which has just introduced Onlive Desktop Plus, which displays a Windows 7 desktop on an iPad, with the full, latest versions of Word, Excel, PowerPoint, Internet Explorer, Adobe Reader, and Flash videos, plus 5 GB of cloud storage.
The trick:a high-speed server farm in the cloud… read more
At this year’s IEEE International Conference on Robotics and Automation, students in the Learning and Intelligent Systems Group at MIT’s Computer Science and Artificial Intelligence Laboratory will present a pair of papers showing how household robots could use a little lateral thinking to compensate for their physical shortcomings.
Many commercial robotic arms perform what roboticists call “pick and place” tasks: The arm picks… read more
It is theoretically possible for time travelers to copy quantum data from the past, according to three scientists in a recent paper in Physical Review Letters.
It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the Grandfather paradox*. He solved the paradox originally using a slight change to quantum theory,… read more
Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.
Planets have previously been found in the habitable zone, but they are all… read more
Rutgers researchers have used carbon nanotubes as a catalyst for splitting water into hydrogen and oxygen, which could replace expensive platinum for making clean-burning hydrogen fuel — which could one day replace expensive, environmentally harmful fossil fuels.
The Rutgers technology is also far more efficient than other low-cost catalysts investigated to date for electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen,… read more
Adherents of “transhumanism” — a movement that seeks to transform Homo sapiens through tools like gene manipulation, “smart drugs” and nanomedicine — hail developments such as prototype bionic eyes and printed tracheas as evidence that we are becoming the engineers of our own evolution.
Transhumanists say we are morally obligated to help the human race transcend its biological limits; those who disagree are sometimes called Bio-Luddites. “The human quest… read more
The first “printed homes” will be coming soon, says World Future Society blogger Thomas Frey.
One construction technology that has great potential for low-cost, customized buildings is “contour crafting — a form of 3D printing that uses robotic arms and nozzles to squeeze out layers of concrete or other materials, moving back and forth over a set path to fabricate a large component.
Structures would be quicker to make,… read more
A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue.
The research, reported in Science Translational Medicine and led by Wyss Institute Core Faculty member David Mooney, Ph.D., lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more.… read more
