Researchers have created the first database of the bacteria colonizing the planet. Called the Earth Microbiome Project, the work involves over 27,000 samples from environments around the world.
It can be hard to know what is true online. Propaganda and misinformation have a much longer history than the internet, of course. But the rapid proliferation of “fake news” on social media, and its tendency to extend into mainstream news coverage, can obscure the difference between credible information and inaccuracies.
Engineers have developed a 4-in-1 smart utilities plant that produces electricity, water, air-conditioning, and heat in an environmentally friendly and cost-effective way.
An accurate analog clock ticks along with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy—10 times as long corresponds to a ten-fold improvement in any frequency uncertainty.
Researchers have created a kind of gel that allows them to grow huge numbers of stem cells with much less space, solving some of the biggest problems with producing new stem cells.
