Comments Off on Rocks in Canada hold oldest evidence of life we’ve found

3.95 billion-year-old rocks could offer the oldest evidence we’ve found for life on Earth . A team led by the University of Tokyo found graphite in Labrador, Canada that they think is biogenic, or produced by living organisms. They contend this is the oldest evidence of life, as opposed to microfossils found earlier in Quebec , saying the dating process used in the latter was highly controversial. In March, the journal Nature published the findings of an international team of researchers who’d found fossils in Quebec that they said could be between 3.77 and 4.28 billion years old. Now, nine scientists at institutions in Japan say they’ve actually found the oldest evidence of life on this planet, and it’s in 3.95 billion-year-old rocks. Related: World’s oldest fossils discovered in Canada – and they’re 4 billion years old These researchers found graphite in sedimentary rocks. Tsuyoshi Komiya of the University of Tokyo said, “Our samples are also the oldest supracrustal rocks preserved on Earth.” Phys.org pointed out the Quebec fossils were found in a similar formation. The Japan team measured the isotope composition of the graphite to find it was biogenic, although the identity of the organisms that produced the graphite or their appearance are mysteries. Komiya said the team could work to identify the organisms by scrutinizing “other isotopes such as nitrogen, sulphur, and iron of the organic matter and accompanied materials.” They can also analyze the rock’s chemical composition to try and figure out the organisms’ environment . Other researchers, like geochemist Daniele Pinti of the University of Quebec at Montreal, seem impressed by the new team’s findings and process. He told CBC News, “For the moment, it looks very convincing.” Phys.org said that should the discovery be accurate, it would mean life sprung up on Earth a geological second after the planet formed around 4.5 billion years ago. Nature published the new study this week. Via Phys.org and CBC News Images via Wikimedia Commons and Tashiro, Takayuki, et al.

High-flying solar balloon farms could harness the sun’s energy miles above the clouds

Comments Off on High-flying solar balloon farms could harness the sun’s energy miles above the clouds

Harnessing the sun’s energy for use here on Earth is a fairly easy thing to do in areas where a lot of sunlight hits the ground (or rooftop, as it were). New developments in solar power technology are working to maximize energy conversion, from capturing as much sunlight as possible to increasing the amount of energy converted . But no solar panel on Earth can do what NextPV is hoping to achieve. The research group is aiming to capture solar energy in the one place where the sun is shining virtually all the time: above the clouds. They say solar balloons floating above the clouds could create high-flying solar farms capable of producing clean energy around the clock.

Origami-inspired “zippered tubes” create super strong structures that fold down flat

Comments Off on Origami-inspired “zippered tubes” create super strong structures that fold down flat

Taking inspiration from origami is nothing new. Kayaks , furniture , museums , and space-based solar panels have all been inspired by the Japanese art of paper folding. The latest origami creation could have applications for everything from nano medicine to space exploration. Researchers from University of Illinois at Urbana-Champaign, the Georgia Institute of Technology and the University of Tokyo have created a “zippered tube” from folding paper that is flexible enough to fold, but stiff enough to support weight. By zippering two tubes together, the team found that they could create a structure that was difficult to twist or bend, but also folds entirely flat.

California passes historic clean energy bill, but not before fossil fuel lobby takes its cut

Comments Off on California passes historic clean energy bill, but not before fossil fuel lobby takes its cut

California lawmakers passed an historic bill on Friday night that requires the state to source 50 percent of its electricity from renewable sources by 2030. While that’s good news for the environment, the bill that got passed was a shadow of its former self. According to ThinkProgress , the version of Bill SB 350 that was passed into law did not include a previous commitment to reduce petroleum use in automobiles by 50 percent, which was removed from the bill days before it was passed, largely due to oil industry lobbying and the defection of a group of moderate democrats.
