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
Addressing a current controversy in physics about information in black holes, “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon.”
Is the world’s only commercial quantum computer really a quantum device, or a just regular computer in disguise? Controversy has long swirled around the computer produced by D-Wave, a company based near Vancouver, Canada.
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
Imagine if doctors could precisely insert a tiny amount of a custom drug into a specific circuit in your brain and improve your depression (or other mood problems) — instead of treating the entire brain.
That’s exactly what Duke University researchers have explored in mice. Stress-susceptible animals that appeared depressed or anxious were restored to relatively normal behavior this way, according to a study appearing in the… 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
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
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
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
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
Increases in life expectancy do not necessarily produce faster overall population aging, according to new open-access research published in the journal PLOS ONE.
This counterintuitive finding was the result of applying new measures of aging, developed at the International Institute for Applied Systems Analysis (IIASA) to future population projections for Europe up to the year 2050.
