Chinese-made unmanned vehicle passes freeway test

January 24, 2013


An unmanned vehicle designed by Military Transportation University of the PLA (MTU) recently won top prize in the fourth Future Challenge, a contest for intelligent vehicles, reports.

The vehicle, a third-generation prototype named “Fierce Lion 3,” completed a 114-kilometer journey within 85 minutes, with a top speed of 105 kilometers per hour, making itself China’s first unmanned vehicle to pass a freeway test.

EPFL’s Institute of Microengineering has reached a remarkable 10.7% efficiency for a single-junction microcrystalline silicon solar cell, surpassing the previous world record of 10.1% held by the Japanese company Kaneka Corporation since 1998.

The efficiency increase was also achieved with with only 1.8 microns of photovoltaic active material — 100 times less material than with standard wafer-based crystalline silicon PV technology.

With our time on Earth coming to an end, a team of explorers undertakes the most important mission in human history: traveling beyond this galaxy to discover whether mankind has a future among the stars.

That’s the theme of the upcoming film Interstellar, directed by Christopher Nolan and starring Matthew McConaughey and Anne Hathaway and opening Nov. 7.

A black hole also plays a key role… read more

Google has officially eaten the newspaper industry

November 16, 2012


Newspapers have continued to churn out the same content while watching their advertisers steadily flee for sites like Craigslist, Yahoo, the Huffington Post/AOL, Facebook, and Google, says writer Will Oremus in Slate Future Tense.  

The chart above, from Statista’s Felix Richter, plots Google’s digital advertising revenue against the print advertising revenue of all U.S.… read more

FBI launches face recognition project

The Next Generation Identification program will include a nationwide database of criminal faces and other biometric data
September 10, 2012


As part of an update to the national fingerprint database, the FBI has begun rolling out facial recognition to identify criminals, New Scientist reports.

It will form part of the bureau’s long-awaited, $1 billion Next Generation Identification (NGI) program, which will also add biometrics such as iris scans, DNA analysis, and voice identification to the toolkit. A handful of states began uploading their photos as… read more

Moore’s Law threatened by lithography woes

October 9, 2012


Moore’s Law is losing steam due to delayed introduction of next-generation extreme ultraviolet lithography (EUV), said experts at the 2012 International Symposium on Extreme Ultraviolet Lithography, EE Times reports.

EUV systems need light sources that are nearly 20 times more powerful than the ones used today to lay down patterns on next-generation chips that target sizes as small as 14 nm. Lithography experts said that… read more

Limb regeneration: do salamanders hold the key?

The secret of how salamanders successfully regrow body parts is being unravelled by University College London (UCL) researchers in a bid to apply it to humans.

For the first time, researchers have found that the “ERK pathway” must be constantly active for salamander cells to be reprogrammed, and hence able to contribute to the regeneration of different body parts.

The team identified a key… read more

Autonomous taxis could be cheaper and improve the environment, says Berkeley Lab study

It’s the year 2030. A fleet of driverless taxis roams throughout your city, ready to pick you up and take you to your destination at a moment’s notice. As a result, greenhouse gases are now 63 to 82 percent lower than with a privately owned hybrid car and 90 percent lower than a 2014 gasoline-powered private vehicle. …

Those numbers are from a new study from Lawrence Berkeley National Laboratory… read more

This Is how Dennis Tito plans to send people to Mars

February 28, 2013


If Dennis Tito has his way, two people will leave our planet in January 2018 and make a trip to Mars and back, with a quick flyby, SpaceRef reports.

The project is being spearheaded by a non-profit organization, the Inspiration Mars Foundation.

Tito’s mission will be facilitated by donors, not investors.

Tito and a group of coauthors from NASA and several aerospace companies… read more

2012 State of the Future

“The world is getting richer, healthier, better educated, more peaceful, and better connected, and people are living longer; yet half the world is potentially unstable,” according to Jerome C. Glenn, CEO of The Millennium Project and co-author of the “2012 State of the Future,” an overview of our global situation, problems, solutions, and prospects for the future.

Researchers at Mayo Clinic have discovered that senescent cells — cells that no longer divide and accumulate with age — shorten lifespan by as much as 35 percent in normal mice.

Removing these aging cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects, the researchers found, writing Feb. 3 in Nature.

“Cellular senescence is a biological mechanism that functions as… read more

Memory capacity of brain is 10 times more than previously thought

The brain’s memory capacity is in the petabyte range, as much as the entire Web, data from the Salk Institute show; may lead to more energy-efficient computers
January 20, 2016

Salk scientists computationally reconstructed brain tissue in the hippocampus to study the sizes of connections (synapses). The larger the synapse, the more likely the neuron will send a signal to a neighboring neuron. The team found that there are actually 26 discrete sizes that can change over a span of a few minutes, meaning that the brain has a far great capacity at storing information than previously thought. Pictured here is a synapse between an axon (green) and dendrite (yellow). (credit: Salk Institute)

Salk researchers and collaborators have achieved critical insight into the size of neural connections, putting the memory capacity of the brain far higher than common estimates. The new work also answers a longstanding question as to how the brain is so energy efficient, and could help engineers build computers that are incredibly powerful but also conserve energy.

“This is a real bombshell in the field of neuroscience,” says … read more

Pupil dilation reveals sexual orientation in new Cornell study

August 7, 2012

Blue Eye Macro

There is a popular belief that sexual orientation can be revealed by one’s pupil dilation when viewing attractive people, but there has been no scientific evidence.

Now Cornell University researchers have confirmed it in an experiment, using a specialized infrared lens to measure pupillary changes in participants watching erotic videos.

Pupils widened most to videos of people who participants found attractive, thereby revealing where they were on… read more
