Summary of an IEEE Spectrum report

In the next few weeks, Google will start shipping its Google Glass to developers. More-polished consumer models are expected in 2014.

Details about Glass are still sketchy but here’s what we know:

  • The lightweight browband, which looks like an ordinary pair of reading glasses minus the lenses, connects to an earpiece that has much the same electronics you’d

Longevity gene that makes Hydra immortal also controls human aging

November 14, 2012

hydra_kiel

Why is the polyp Hydra immortal? Researchers from Kiel University decided to study it — and unexpectedly discovered a link to aging in humans.

The study carried out by  together with the Keil University Medical Center Schleswig-Holstein (UKSH)

The tiny freshwater polyp Hydra does not show any signs of aging and is potentially immortal. There is a rather simple biological explanation for this: these animals exclusively reproduceread 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

Morality for robots?

September 5, 2012

machine-question-book

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

Resveratrol counteracts effects of exercise in older men

July 24, 2013

resveratrol

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:

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

Physicists solve uncertainty about uncertainty principle

September 10, 2012

uncertainty-12_09_07

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

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

Taking 3D printing into the metal age

October 16, 2013

mars_probe_3d_printed

The European Space Agency (ESA)and the EU, together with industrial and educational partners, are developing the first large-scale production methods to 3D-print complex 3D-printed parts made of metal that can withstand temperatures at 1000°C — fit for space and the most demanding applications on Earth.

3D printers are expected to revolutionize the way we live but until recently they could work with only plastic, which… read more

Five potential habitable exoplanets now

Exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet
July 25, 2012

Gliese 581g

New data suggests the exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet. The nearby star Gliese 581 — located about 20 light years away from Earth in the constellation Libra — has four planets; the outermost planet, Gliese 581d, was already suspected habitable.

This will be the first evidence for any two potential habitable exoplanets that are orbiting the same star.

Google DeepMind’s machine-learning AlphaGo program has defeated South Korean Go champion Lee Sedol in the first match of five historic matches between human and AI, taking place in Seoul.

The second round will take place today (Wednesday March 9 in U.S.) at 11 PM ET (1 PM KST), also covered on YouTube.

Last October, AlphaGo defeated European Go champion Fan Hui 5-0, making it the first… read more

Could robots become ‘aware’ of their own limitations?

April 3, 2013

(credit: Allegra Boverman and Christine Daniloff/MIT)

MIT researchers have developed software for robots that enables them to be more “aware” of their own limitations, such as knowing the whereabouts of an object, or its own location within a room.

Most successful robots today tend to be used either in fixed, carefully controlled environments, such as manufacturing plants, or for performing fairly simple tasks such as vacuuming a room,

But carrying out complicated sequences… read more

World’s biggest geoengineering experiment ‘violates’ UN rules

Brace yourself for a tidal wave of Facebook campaigning before November’s U.S. presidential election. A study of 61 million Facebook users finds that using online social networks to urge people to vote has a much stronger effect on their voting behavior than spamming them with information via television ads or phone calls, Science Now reports.

The study follows a Science paper that tracked howread more
