Catch Oil Polluters With Open Source Tools Using the Homebrew Oil Testing Kit

Slashdot - Thu, 25/09/2014 - 7:39pm
First time accepted submitter jywarren writes Ever wish you could investigate pollution yourself? Public Lab's recently announced open source kit aims to make it possible for anyone to become a "pollution detective" by comparing samples of oil contamination. Under the hood, the kit is pretty interesting. It uses the ultraviolet fluorescence caused by a Blu-Ray laser pen in oil samples, and includes a "papercraft" spectrometer to scan and classify oil types. The group's Kickstarter campaign is also seeking 50 early-access beta testers to help test and refine the kit before release.

On the road to artificial photosynthesis: Study reveals key catalytic factors in carbon dioxide reduction

Science Daily - Thu, 25/09/2014 - 7:08pm
The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy. That is the lure of artificial photosynthesis in which the electrochemical reduction of carbon dioxide is used to produce clean, green and sustainable fuels. However, finding a catalyst for reducing carbon dioxide that is highly selective and efficient has proven to be a huge scientific challenge. New experimental results have revealed the critical influence of the electronic and geometric effects in the carbon dioxide reduction reaction and might help make the problem easier to tackle.

Longstanding bottleneck in crystal structure prediction solved

Science Daily - Thu, 25/09/2014 - 7:08pm
The various patterns that atoms of a solid material can adopt, called crystal structures, can have a huge impact on its properties. Being able to accurately predict the most stable crystal structure for a material has been a longstanding challenge for scientists. Researchers calculated the lattice energy of benzene, a simple yet important molecule in pharmaceutical and energy research, to sub-kilojoule per mole accuracy -- a level of certainty that allows polymorphism to be resolved.

Playing the Field: The Sport of Today’s Venture Capital for Innovation

Wired News - Thu, 25/09/2014 - 7:03pm

“Let him who would enjoy a good future waste none of his present.” Those words, from early 20th century investor Roger Babson, are an accurate reflection of the watchful VC investing we’ve seen in the last quarter. VCs are hesitant to place big bets on the untested start-up, often holding back until the later stage financing […]

Drones Reveal Widespread Tax Evasion In Argentina

Slashdot - Thu, 25/09/2014 - 6:46pm
Tailhook (98486) writes "The Argentine government has used drones to reveal 200 homes and 100 pools in an upper class area about ten miles south of Buenos Aires that had not been detailed on tax returns. Tax officials said the drones took pictures of luxury houses standing on lots registered as empty. The evasions found by the drones amounted to missing tax payments of more than $2 million and owners of the properties have been warned they now face large fines."

Solar System's Water Is Older Than the Sun

Slashdot - Thu, 25/09/2014 - 6:20pm
astroengine writes Next time you're swimming in the ocean, consider this: part of the water is older than the sun. So concludes a team of scientists who ran computer models comparing the ratios of hydrogen isotopes over time. Taking into account new insights that the solar nebula had less ionizing radiation than previously thought, the models show that at least some of the water found in the ocean, as well as in comets, meteorites and on the moon, predate the sun's birth.

How to make stronger, 'greener' cement: New formula could cut greenhouse-gas emissions

Science Daily - Thu, 25/09/2014 - 6:12pm
Concrete is the world's most-used construction material, and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse-gas emissions. Now a new study suggests a way in which those emissions could be reduced by more than half -- and the result would be a stronger, more durable material.

Efficiently harvesting hydrogen fuel from Sun using Earth-abundant materials

Science Daily - Thu, 25/09/2014 - 6:12pm
Scientists have a new efficient way of producing hydrogen fuel from sunlight and water. By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using Earth-abundant materials as opposed to rare metals.
