Researchers at Bell Labs in New Jersey say they’ve used compressive sensing to build a camera that needs no lens and uses only a single sensing pixel to take photographs, MIT Technology Review reports.

What’s more, the images from this camera are never out of focus.

The invention could revolutionize optical, infrared and millimeter-wave imaging

This revolutionary lensless camera has a number of advantages over… read more

Quantum robots will be more creative, faster, smarter, say researchers

Quantum computing should be applied to robots, automatons, and other agents that use AI to make them more creative and to learn and respond faster than conventional robots, researchers from the Complutense University of Madrid (UCM) and the University of Innsbruck (Austria) recommend.

In a study in the journal ‘Physical Review X’ modeling the use of quantum physics in future robots (and other agents), they demonstrate that… read more

2045: The Year Man Becomes Immortal

February 10, 2011


Time magazine just published a comprehensive cover story on the Singularity and Ray Kurzweil’s “radical vision for humanity’s immortal future.”

“Kurzweil’s interest in humanity’s cyborganic destiny began about 1980 largely as a practical matter. He needed ways to measure and track the pace of technological progress…(Kurzweil) has been publishing his thoughts about the future of human and machine-kind for 20 years, most recently in The Singularity Isread more

3D printing lowers environmental impact, says study

October 5, 2013


Making things at home on a 3D printer uses less energy — and therefore releases less carbon dioxide — than producing it in a factory and shipping it to a warehouse.

That’s according to a study led by Joshua Pearce, an associate professor of materials science and engineering/electrical and computer engineering at Michigan Technological University.

The team conducted life-cycle impact analyses on three products:… read more

Could we build a 20-kilometer-high space tower?

September 12, 2012

Science-fiction novelist Neal Stephenson imagines a 20-kilometer-high steel tower that reaches into the stratosphere.

From that height, planes could save fuel by docking at the tower rather than landing, and space missions could do the same by launching from it.

Stephenson is teaming up with a structural engineer, Keith Hjelmstad at Arizona State University (ASU), to work out how to actually build the tower, New Scientist reports.… read more

How the brain ‘takes out the trash’ while we sleep

October 18, 2013


A new study shows that a recently discovered system that flushes waste from the brain is primarily active during sleep, giving fresh meaning to the old adage that a good night’s sleep clears the mind.

This revelation could transform scientists’ understanding of the biological purpose of sleep and point to new ways to treat neurological disorders.

“This study shows that the brain has different functional states… read more

The future of education eliminates the classroom, because the world is your class

March 25, 2013

Technology can turn our entire lives into learning experiences via “socialstructed learning,” an aggregation of microlearning experiences drawn from a rich ecology of content and driven not by grades but by social and intrinsic rewards, suggests Marina Gorbis, Executive Director at the Institute for the Future, in Fast Company.

“Today’s obsession with MOOCs is a reminder of the old forecasting paradigm: In the early stages of technology… read more

Disruptions: on the fast track to routine 3D printing

February 19, 2013


Hod Lipson, an associate professor and the director of the Creative Machines Lab at Cornell, said “3D printing is worming its way into almost every industry, from entertainment, to food, to bio- and medical-applications,” The New York Times reports.

Dr. Lipson, the co-author of “Fabricated: The New World of 3D Printing,” said… read more

Morality for robots?

September 5, 2012


In new book, NIU Northern Illinois University Professor David Gunkel examines ethical questions raised by 21st century computers, robots and artificial intelligence.

On the topic of computers, artificial intelligence and robots,  he says science fiction is fast becoming “science fact.”

Fictional depictions of artificial intelligence have run the gamut from the loyal Robot in “Lost in Space” to the killer computer HAL in “2001:… read more

Paul Allen: the Singularity isn’t near

October 13, 2011

The Microsoft cofounder and a colleague say the Singularity is a long way off.

Their main issue: the “complexity brake. As we go deeper and deeper in our understanding of natural systems, we typically find that we require more and more specialized knowledge to characterize them, and we are forced to continuously expand our scientific theories in more and more complex ways…. Without having a scientifically deep understanding of… read more

Resveratrol counteracts effects of exercise in older men

July 24, 2013


Resveratrol — a natural antioxidant compound found in red grapes and other plants — counteracts many of the cardiovascular benefits of exercise in older men,  including reduced blood pressure and cholesterol, according to research conducted at The University of Copenhagen.

Lasse Gliemann, a PhD student who worked on the study at The University of Copenhagen, explains how they conducted the research, and the results they found:

“We… read more

First spin-entangled electrons on a chip

July 2, 2015

False colour scanning image-ft

A team from the RIKEN Center for Emergent Matter Science, along with collaborators from the University of Tokyo and University of Osaka, have successfully produced pairs of spin-entangled electrons and demonstrated, for the first time, that these electrons remain entangled even when they are separated from one another on a chip.

This research could allow information contained in quantum bits (qubits) to be shared between… read more

Physicists solve uncertainty about uncertainty principle

September 10, 2012


The Heisenberg uncertainty principle is one of the cornerstones of quantum mechanics: it’s impossible to measure anything without disturbing it.

For instance, any attempt to measure a particle’s position must change its momentum.

But never mind all that. It’s wrong, University of Toronto physicists say they have just proven.

(This has important implications for quantum information and especially quantum cryptography, where it is fundamental to the security of certain protocols.)… read more

A strange computer promises great speed

March 25, 2013


Academic researchers and scientists at companies like Microsoft, IBM, and Hewlett-Packard have been working to develop quantum computers.

Now, Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to… read more

Planets could orbit singularities inside black holes

November 10, 2011

Black hole orbit

Certain black holes can have a complex internal structure that could allow photons, particles, and perhaps even planets to orbit the central singularity without ever getting sucked all the way in, Technology Review Physics arXiv Blog reports.

“Advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei without being visible from the outside,” says Vyacheslav Dokuchaev, Institute for Nuclear Research of the Russian… read more
