NASA’s Kepler mission has discovered the first near-Earth-size planet in the “habitable zone” around a Sun-like star. This discovery joins 11 other new small habitable zone candidate planets, marking another milestone in the journey to find another “Earth.”

The newly discovered Kepler-452b, located 1,400 light-years away in the constellation Cygnus, is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid… read more

Civilization faces ‘perfect storm of ecological and social problems’

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

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

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

Your memory can be altered by interfering information

You can manipulate an existing memory simply by suggesting new or different information, Iowa State University researchers have shown.

The key is timing and recall of that memory, said Jason Chan, an assistant professor of psychology at Iowa State.

“If you reactivate a memory by retrieving it, that memory becomes susceptible to changes again. And if at that time, you give people new contradictory… read more

Russian billionaire Yuri Milner, Stephen Hawking, Martin Rees, Frank Drake and others announced at The Royal Society today $100 million funding for Breakthrough Listen — the “most powerful, comprehensive, and intensive scientific search ever undertaken for signs of intelligent life beyond Earth.”

They also announced $1 million prize funding for Breakthrough Message, a competition to generate messages representing humanity and planet Earth.

A challenge facing designers of future computer chips

November 8, 2012

The total conductance per unit area is similar for both tungsten (W) and gold (Au). However, by joining the two highly conducting metals, one finds a conductance density that is about 4 times lower of either material individually. (Credit: David J. Olivera et al./PNAS)

To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.

Researchers at at McGill University General Motors R&D, have shown that electrical current could be drastically reduced when wires from two dissimilar metals meet. The surprisingly sharp reduction in current reveals a significant challenge… read more

MIT researchers have developed a new application of carbon nanotubes that shows promise as an innovative approach to storing solar energy for use whenever it’s needed.

Storing the sun’s heat in chemical form — rather than first converting it to electricity or storing the heat itself in a heavily insulated container — has… read more

Are three-person designer babies ethical?

The Hastings Center asks how should parents determine what sort of child they have?

From genetic and genomic testing to new techniques in human assisted reproduction, various technologies are providing parents with more of a say about the children they have and “stirring the pot of designer baby concerns,” writes Thomas H. Murray, President Emeritus of The Hastings Center, in a commentary in Science.

Murray calls for a national conversation about how much discretion would-be parents should have. “Preventing a lethal… read more

What does the assistive robot of the future look like?

October 16, 2013

human vs robot face

It depends. Older and younger people have varying preferences about what they would want a personal robot to look like, and they change their minds based on what the robot is supposed to do, a new study from the Georgia Institute of Technology has found.

Participants were shown a series of photos portraying either robotic, human, or mixed human-robot faces and were asked to select… read more

Harvard scientists to build Iron Man-like suit for military

July 26, 2012


Harvard University scientists are working on an Iron Man-like smart suit that could improve soldiers’ endurance in war zones, Network World reports.

The university received a $2.6 million research grant for the project from DARPA.

The suit, which is expected to include sensors and its own energy source, will be designed to delay the onset of fatigue, enabling soldiers to travel further in the field, while… read more

The Ivanpah Solar Electric Generating System in California’s Mojave Desert produced its first output of energy when the first of three towers was synchronized last week to the power grid for the first time.

Power generated from Ivanpah will first go to Pacific Gas and Electric (PG&E), followed by Southern California Edison in the coming months.

Ivanpah is the largest solar thermal plant in the… read more

A cardboard bike

October 18, 2012


Working from his garden shed, Israeli inventor Izhar Gafni has invented a $20 cardboard bike, says The Telegraph.

The solid tires are made of reconstituted rubber from old car tires and some proprietary materials have been added for water protection and other purposes.

“This is a real game changer,” said Nimrod Elmish, Gafni’s business partner. ”It changes … the way products are manufactured and shipped, it causes factories to… read more
