Amateur spots birth of a supernova — Victor Buso was testing his camera-telescope setup in Argentina back in September 2016, pointing his Newtonian telescope at a spiral galaxy called NGC613. He collected light from the galaxy for the next hour-and-a-half, taking short exposures to avoid the Santa Fe city lights. When he looked at his images, he realised he’d captured a potential supernova: an enormous flash of light an energy bursting off of a distant star.
~ Superlative serendipity.
Earth’s incredible, but is there anything else remotely like it? Aki Roberge, research astrophysicist at NASA, explained Earth is the only planet we know of where the presence of life has altered the atmosphere’s chemistry. If another Earth-like planet existed somewhere in the universe, we might be able to spot it by looking for a biosignature: spectral lines from chemicals such as methane, water vapour, oxygen, or other organic molecules indicative of life.

New way to use DNA as a storage device — Researchers from the Waterford Institute of Technology (WIT) in Ireland have developed a way to use bacteria to archive up to up to one zettabyte in one gram of DNA. The technique uses double-strained DNA molecules called plasmids to encode data which is stored in the Novablue strain of the E Coli bacteria.

Model brains reveal brain-folding physics — Brains fold in on themselves as they grow. How and why they do it is mysterious and studying it requires some pretty interesting science.
Israeli scientists wanted to study brain folding from a physics perspective. Growing brain cells for study can be difficult, though — so they came up with a solution to overcome this obstacle: growing simple mini-brains on a chip under a microscope.

Modernist cooking needs gadgets, tools and precise measurements— Science requires precision, and these tools allow you to combine perfect amounts and get perfect results. Ryan F Mandelbaum learns to cook like a gadget nerd.
~ This is why you don’t accept dinner invitations from scientists. Crikey, talk about deleting all joy from the kitchen!
Antimatter in a van — Normally, scientists produce volatile antimatter in the lab, where it stays put in an experimental apparatus for further study. But now, researchers are planning on transporting it for the first time from one lab to another in a truck.

Big data suggest urban farming — It makes intuitive sense that growing crops as close as possible to the people who will eat them is more environmentally friendly than long-distance shipping, but evidence that urban agriculture is good for the environment has been harder to pin down.
A widely cited 2008 study by researchers at Carnegie Mellon University found that transportation from producer to store only accounts for 4% of food’s total greenhouse gas emissions, which calls into question the concern over “food miles.” A recent analysis of urban agriculture’s global potential, published in the journal Earth’s Future, has taken a big step toward an answer—and the news looks good for urban farming.
~ And there are co-benefits, from social implications to urban heat reduction.
Plants appeared earlier than thought — For hundreds of millions of years, life on Earth was a purely aquatic phenomenon. The jump from the oceans to the continents was a monumental event, one that would irrevocably change the face of our planet. A new study suggests the first plants to make this evolutionary leap appeared much earlier than previously thought, and this affects our modelling of Earth’s atmosphere changes wrought by their impact.
~ Although that is a previous thought I haven’t previously thought.
