How to store solar energy more cost-effectively for use at night

November 7, 2014

There’s currently no cost-effective, large-scale way to store solar energy, but Stanford researchers have developed a solution: using electrolysis to turn tanks of water and hydrogen into batteries. During the day, electricity from solar cells could be used to break apart water into hydrogen and oxygen. Recombining these gases would generate electricity for use at night.

There’s one major problem. Electrolysis uses electricity to crack the chemical bonds that… read more

Real-world stereotypes continue to exist in virtual worlds

May 6, 2015


Stereotypes related to gender and appearance that burden women in the real world could follow them into virtual ones, according to Penn State researchers.

In a study of how people interacted with avatars in an online game, women received less help from fellow players than men when they operated an unattractive avatar and when they used a male avatar, said T. Franklin Waddell, a doctoral candidate in massread more

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.

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.

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

‘Neural dust’ brain implants could revolutionize brain-machine interfaces and allow large-scale data recording

July 17, 2013

Neural dust

In a potential neuroscience breakthrough, University of California Berkeley scientists have proposed a system that allows for thousands of ultra-tiny “neural dust” chips to be inserted into the brain to monitor neural signals at high resolution and communicate data highly efficiently via ultrasound.

The neural dust design promises to overcome a serious limitation of current invasive brain-machine interfaces (BMI): the lack of an implantable neural interface system that remains… read more

Queen Mary University of London researchers have developed a Google Play app called Phoney based on a mind-reading card trick, part of a research exploration into what can be achieved when human intelligence is replaced or assisted by machine intelligence.

The app arranges a deck of playing cards in such a way that a specific card picked by an audience member can beread 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

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
