A cost-effective nanotube-based catalyst for producing hydrogen fuel

July 28, 2014

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

How to become the engineers of our own evolution

March 20, 2012

singularityfringe

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

Printable houses are coming

April 11, 2012

Italian inventor Enrico Dini, chairman of Monolite UK Ltd, has developed a huge three-dimensional printer called D-Shape that can print entire buildings out of sand and an inorganic binder. The printer works by spraying a thin layer of sand followed by a layer of magnesium-based binder from hundreds of nozzles on its underside. The glue turns the sand to solid stone, which is built up layer-by-layer from the bottom up to form anything from a sculpture to a sandstone building. (Credit: Monolite)

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

tooth regeneration

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

The threat of silence

Meet the groundbreaking new encryption app set to revolutionize privacy and freak out the feds

For the past few months, some of the world’s leading cryptographers have been keeping a closely guarded secret about a pioneering new invention. Today, they’ve decided it’s time to tell all, Slate Future Tense reports.

Back in October, the startup tech firm Silent Circle ruffled governments’ feathers with a “surveillance-proof” smartphone app to allow people to make secure phone calls and send texts… read more

Brain-boosting technique might help some functions while hurting others

transcranial_stimulation

Electrically stimulating the brain may enhance memory, but impede a person’s ability to react without thinking, MIT Technology Review reports.

Using a noninvasive technique called transcranial electrical stimulation (TES) to stimulate the brain, researchers found they could enhance learning when they targeted a certain spot.

But that also made people worse at automaticity, or the ability to perform a task without really thinking about it. Stimulating another… read more

World’s first green piglets born in China, sheep next

In Guangdong Province in Southern China, ten transgenic piglets have been born this year, in  and under a black light, they glow a greenish tint.

A technique developed by reproductive scientists from the University of Hawai`i at Mānoa’s John A. Burns School of Medicine was used to quadruple the success rate at which plasmids carrying a fluorescent protein from jellyfish DNA were transferred into the… read more

Real or computer-generated: can you tell the difference?

Training helps humans tell them apart ... but soon, only computers will know what's real or not
February 22, 2016

A Dartmouth College study shows that people find it increasingly difficult to distinguish between computer-generated images and real photos, but that a small amount of training greatly improves their accuracy. (credit: Dartmouth College)

As computer-generated characters become increasingly photorealistic, people are finding it harder to distinguish between real and computer-generated, a Dartmouth College-led study has found.

This has introduced complex forensic and legal issues*, such as how to distinguish between computer-generated and photographic images of child pornography, says Hany Farid, a professor of computer science, pioneering researcher in digital forensics at Dartmouth, and senior author of a paper… read more

New results indicate that new particle is a Higgs boson

March 14, 2013

An example of simulated data modelled for the CMS particle detector on the Large Hadron Collider (LHC) at CERN. Here, following a collision of two protons, a Higgs boson is produced which decays into two jets of hadrons and two electrons. The lines represent the possible paths of particles produced by the proton-proton collision in the detector while the energy these particles deposit is shown in blue. (Image credit: CERN)

At the recent Moriond Conference, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) presented preliminary new results, finding that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles.

It remains an open question, however, whether this is the Higgs… read more

Flexible sensors turn skin into a touch-sensitive interface for mobile devices

March 4, 2015

iSkin2

Computer scientists at Saarland University and Carnegie Mellon University are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin.

By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be… read more

Are populations aging more slowly than we think?

60 is the new middle age

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.

IIASA World Population Program Deputy Director Sergei Scherbov led… read more

D-Wave Systems breaks the 1000 qubit quantum computing barrier

D-Wave Systems has broken the quantum computing 1000 qubit barrier, developing a processor about double the size of D-Wave’s previous generation, and far exceeding the number of qubits ever developed by D-Wave or any other quantum effort, the announcement said.

It will allow “significantly more complex computational problems to be solved than was possible on any previous quantum computer.”

At 1000 qubits, the new processor considers 21000 possibilities… read more

New solar structure cools buildings in full sunlight, replacing air conditioners

Homes and buildings chilled without air conditioners? Car interiors that don't heat up in the summer sun? Tapping the frigid expanses of outer space to cool the planet? Yes.

Stanford University researchers have designed an entirely new form of cooling structure that cools even when the sun is shining, eliminating the need for air conditioning.

Such a structure could vastly improve the daylight cooling of buildings, cars, and other structures by reflecting sunlight back into space.

“We’ve developed a new type of structure that reflects the vast majority of sunlight, while at the same… read more

Thiel tells Schmidt: ‘Google is out of ideas’

July 18, 2012

Google Chairman Eric Schmidt and investor Peter Thiel took aim at each other in a recent debate, CNET reports.

Schmidt said technology and access to information has increased productivity and quality of life worldwide. Thiel thanked Schmidt for “doing a fantastic job” as “minister of propaganda” for Google. The tech sector has made remarkable strides in the areas of computers and software, he said, but has seen a “catastrophic” failure in other… read more
