Another Earth just 12 light-years away?

December 19, 2012

Astronomers have discovered what may be five planets orbiting Tau Ceti, the closest single star beyond our solar system whose temperature and luminosity nearly match the sun’s, Science Now reports.

If the planets are in fact there, one of them is about the right distance from the star to sport mild temperatures, oceans of liquid water, and even life, and slight changes in Tau Ceti’s… read more

A simple fuel cell for home use has been developed by Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Germany and heater manufacturer Vaillant.

With an output of one kilowatt, they cover the average current consumption for a four-person household.

Fuel cells convert natural gas directly into electrical energy. They are many times more efficient than are combustion engines, such as the car engine.… read more

University of Auckland researchers have proposed a new method for finding Earth-like planets in our galaxy and they anticipate that the number will be on the order of 100 billion.

The research supports an earlier estimate based on extrapolations of Kepler data.

The new research uses a technique called gravitational microlensing, currently used by a Japan-New Zealand collaboration called MOA (Microlensing Observations in Astrophysics)… read more

DARPA’s four-legged robots ace tests in demo

September 13, 2012

newls3-0

DARPA’s Legged Squad Support System (LS3) program demonstrated two robotic “pack mule” prototypes for the Commandant of the Marine Corps, Gen. James F. Amos, and DARPA Director, Arati Prabhakar.

The goal of the LS3 program is to demonstrate that a legged robot can unburden dismounted squad members by carrying their gear, autonomously following them through rugged terrain, and interpreting verbal and visual commands.

The House on Wednesday unanimously passed a Senate resolution introduced by Sens. Claire McCaskill (D-Mo.) and Marco Rubio (R-Fla.) that calls on the U.S. government to oppose United Nations control of the Internet, The Hill’s Floor Action Blog reports.

The 397-0 vote is meant to send a signal to countries meeting at a U.N. conference on telecommunications this week. Participants are meeting to update an international telecom… read more

Carver Mead: ‘A bunch of big egos’ are strangling science

The scientific revolution has stalled, here's how to kickstart it
February 22, 2013

ISSCC Microelectronics pioneer, Caltech professor emeritus, and all-around smart guy Carver Mead believes that the scientific revolution that began with the discovery of special relativity and quantum mechanics has stalled, and that it’s up to us to kickstart it, The Register reports.

“A bunch of big egos got in the way,” he told his audience of 3,000-plus chipheads at the International Soild-State Circuits Conference (ISSCC)… read more

Is this the biggest breakthrough in propulsion since the jet engine?

November 30, 2012

Reaction Engines Ltd. has announced what is says is the “biggest breakthrough in aerospace propulsion technology since the invention of the jet engine.”

Critical tests have been successfully completed on the key technology for SABRE, an engine that will enable aircraft to reach the opposite side of the world in under four hours, or to fly directly into orbit and return in a single stage,… read more

New York to Beijing in two hours without leaving the ground?

March 26, 2012

maglev-vacuum-train-11

The Evacuated Tube Transport (ETT) system (U.S. Patent 5950543, assigned to ET3.com, Inc.) would take passengers from New York to Beijing in just two hours. Advocates of Evacuated Tube Transport (ETT) claim it is silent, cheaper than planes, trains, or cars and faster than jets.

How it would work: put a superconducting maglev train in evacuated tubes, then accelerate using linear electric motors until the design velocity is attained. Passive superconductors… read more

‘Big data’ and cloud computing empower smart machines to do human work, take human jobs

From giant corporations to university libraries to start-up businesses, employers are using rapidly improving technology to do tasks that humans used to do.

That means millions of workers are caught in a competition they can’t win against machines that keep getting more powerful, cheaper and easier to use, the Washington Post reports.

To better understand the impact of technology on jobs, The Associated Press analyzed employment… read more

DARPA shows off 1.8-gigapixel surveillance drone, can spot a terrorist from 20,000 feet

ARGUS

DARPA and the US Army have taken the wraps off ARGUS-IS, a 1.8-gigapixel video surveillance platform that can resolve details as small as six inches from an altitude of 20,000 feet (6km), ExtremeTech reports.

ARGUS is by far the highest-resolution surveillance platform in the world, and probably the highest-resolution camera in the world, period.

ARGUS, which would be attached to some kind of unmanned UAV (such as… read more

Huge Mars colony eyed by SpaceX founder Elon Musk

November 25, 2012

Elon Musk, the billionaire founder and CEO of the private spaceflight company SpaceX, wants to help establish a Mars colony of up to 80,000 people by ferrying explorers there for perhaps $500,000 a trip, Space.com reports.

In Musk’s vision, the ambitious Mars settlement program would start with a pioneering group of fewer than 10 people.

Hyperloop passenger transport

Elon Musk has published a blog post detailing the Hyperloop concept; a solar-powered, elevated transit system that could take passengers and cars from Los Angeles to San Francisco in 30 minutes.

Here are the core designs. Bloomberg has further details.

A new — and reversible — cause of aging

NAD, a naturally produced compound in cells, rewinds aspects of age-related demise in mice
December 20, 2013

sirt1_protein

Researchers have discovered a cause of aging in mammals that may be reversible: a series of molecular events that enable communication inside cells between the nucleus and mitochondria.

As communication breaks down, aging accelerates. By administering a molecule naturally produced by the human body, scientists restored the communication network in older mice. Subsequent tissue samples showed key biological hallmarks that were comparable to those of much younger animals.… read more

Shapeways, a Netherlands-based online 3D printing company, has opened a “factory of the future” in Queens, New York that plans to house 50 high-resolution industrial 3D printers and print custom-designed products a year, Popular Science reports.

The company will allow customers to upload custom 3D designs, and then prints them using materials including acrylic, nylon, glass, gypsum, ceramic, and sandstone, and precious metals such as silver, and ships the… read more

Email services close and destroy data rather than reveal files

Lavabit, a Texas-based service that was reportedly used by Edward J. Snowden, announced the suspension of its service Thursday afternoon to avoid being “complicit in crimes against the American people,” The New York Times reports.

Within hours, a fast-growing Maryland-based start-up called Silent Circle also closed its e-mail service and destroyed its e-mail servers.

In effect, both businesses destroyed their assets — in part or in… read more
