    The E in E. coli now stands for electronics
    An engineered gene control circuit allows the bacteria to form a template for metal.
    ...
    An exception to this was reported in this week's edition of Nature Biotechnology. A team at Duke University has engineered a bacterial population that uses engineered genetic circuitry to express a protein only in specific locations. The researchers then printed these bacteria onto a surface and processed them to coat the protein in gold. The result is a tiny gold dome that makes a great pressure sensor.

    Warning of "Ecological Armageddon" After 75% Plunge in Insect Numbers

    The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists. The cause of the huge decline is as yet unclear, although the destruction of wild areas and widespread use of pesticides are the most likely factors and climate change may play a role. The scientists were able to rule out weather and changes to landscape in the reserves as causes, but data on pesticide levels has not been collected.

    Ancient mutation helped create delicious, fatty pork. Scientists just fixed it

    The engineering created hardier, leaner pigs that the scientists argue will improve pig welfare and cut losses and energy use on farms. Publishing data on their genetically modified pigs in PNAS, the scientists don’t mention anything about how the new pigs will taste.

    The world's biggest grave robbery: Asia’s disappearing WWII shipwrecks
    Exclusive: the unmarked graves of thousands of sailors are threatened by illegal metal salvagers
    ...
    The rusted 70-year-old wrecks are usually sold as scrap but the ships also contain valuable metals such as copper cables and phosphor bronze propellors.

    Experts said grave diggers might be looking for even more precious treasures – steel plating made before the nuclear testing era, which filled the atmosphere with radiation. These submerged ships are one of the last sources of “low background steel”, virtually radiation-free and vital for some scientific and medical equipment.

    Huge news: scientists solve mystery of dead male woolly mammoths
    ...
    Much like wild elephants today, young male Ice Age mammoths probably roamed alone and more often got themselves into risky situations where they were swept into rivers, fell through ice or into bogs or sinkholes that preserved their bones for thousands of years, scientists say.

    Females, on the other hand, travelled in a group led by an older matriarch who knew the terrain and steered her counterparts away from danger.

    Aluminum Really Can Improve Your Wireless Performance

    Get rid of that Pringles can and aluminum because you can now 3-D print a cheap, customized reflector that directs wireless signals to where users need them most. A team of Dartmouth College researchers has finally solved the problem of how to inexpensively improve indoor spaces with multiple rooms. According to the research team you can spend $35 on a wireless reflector that can be custom-built to outperform expensive antenna solutions.

    Human Mini-Brains Growing Inside Rat Bodies Are Starting to Integrate

    Starting on November 11, an annual meeting of the Society for Neuroscience will convene in Washington, D.C. Among the group will be two teams of researchers that plan to present reports on unexpected interaction between organoids and their rodent hosts.
    Organoids are tiny human like brains that scientists are implanting into rats and mouse as well as other animals for researching the human brain. The most advanced organoids have been found to connect to the host animals circulatory and nervous system creating human axons in the brains. Although we shouldn't worry too much yet as the size of the brains are still relatively small and cannot grow large enough to even mimic our own.

    Bacteria Found on International Space Station May Be Alien in Origin

    Bacteria found on the outside of the International Space station could be alien life, according to Anton Shkaplerov, a Russian cosmonaut who has served on board the space lab. Finding bacteria that came from somewhere other than Earth would be one of the biggest breakthroughs in the history of science -- but much more must be done before such a claim is made.

    Scientists Create Stretchable Battery Made Entirely Out of Fabric
