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

When machines do your job

Researcher Andrew McAfee says advances in computing and artificial intelligence could create a more unequal society
July 13, 2012

Are American workers losing their jobs to machines?

That was the question posed by Race Against the Machine, an influential e-book published last October by MIT business school researchers Erik Brynjolfsson and Andrew McAfee.

The pair looked at troubling U.S. employment numbers — which have declined since the recession of 2008-2009 even as economic output has risen — and concluded that computer technology was… 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

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.

The U.S. should create a new agency dedicated to manned exploration of the moon, Mars and other destinations in deep space, says former Apollo astronaut Harrison Schmitt, Space.com reports.

Schmitt suggests the new agency be called the National Space Exploration Administration.

The new deep-space agency should “stay young, and develop a management structure that is not so hierarchical — that is actually a… read more

Is this Elon Musk’s secret design for a high-speed train?

July 16, 2013

Hyperloop2

Elon Musk has been hinting at an idea he calls the Hyperloop — a ground-based transportation technology that would get people from Los Angeles to San Francisco in under half an hour, for less than 1/10 the cost of California’s $69 billion plan.

On Monday, Musk tweeted that he will publish an “alpha design” for the Hyperloop by Aug. 12. As Slateread more

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

Celebrated scientists and development thinkers today warn that civilization is faced with a perfect storm of ecological and social problems driven by overpopulation, overconsumption, and environmentally malign technologies.

In the face of an “absolutely unprecedented emergency,” say the 18 past winners of the Blue Planet prize — the unofficial Nobel for the environment — society has “no choice but to take dramatic action to avert a collapse of civilisation. Either we… read more

Chief Deputy Randy McDaniel of the Montgomery County Sheriff’s Office in Texas said his department is considering using rubber bullets and tear gas on its drone, CBS DC reports.

“Drone manufacturers are also considering offering police the option of arming these remote-controlled aircraft with (nonlethal for now) weapons like rubber bullets, Tasers, and tear gas,” the ACLU says on their website.

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

September 12, 2012

(NASA MSFC, Artist Pat Rawling)

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

2045: The Year Man Becomes Immortal

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

Teleporting people through space, as in Star Trek, is impossible by the laws of physics, but researchers at TU Delft‘s Kavli Institute of Nanoscience have succeeded in teleporting information.

Using quantum entanglement, they transferred the information contained in a quantum bit in a diamond to a quantum bit in another diamond three meters away, without the information having traveled through the intervening space.

Scientists at Albert Einstein College of Medicine of Yeshiva University have found that the hypothalamus of mice controls aging throughout the body.

Their discovery of a specific age-related signaling pathway opens up new strategies for combating diseases of old age and extending lifespan.

Background: the hypothalmus and inflammation

“Scientists have long wondered whether aging occurs independently in the body’s various tissues or if it… read more
