writes: BBC reports that results of a study of the spectrum of light emitted by 23,000 red, passive galaxies and 4,000 blue, star-forming ones shows that when galaxies stop making stars, their death is usually a slow process that chokes them of the necessary cool gases over about four billion years. Astronomers surveyed thousands of galaxies, living and dead, to assess whether the transition is rapid or slow. In the dead galaxies they detected high levels of metals, which build up during star formation and point to a slow strangulation process. "Metals are a powerful tracer of the history of star formation: the more stars that are formed by a galaxy, the more metal content you'll see," says Dr Yingjie Peng. "So looking at levels of metals in dead galaxies should be able to tell us how they died."

writes: If there's nothing else that science has to offer, it's this elegant notion: that anyone, anywhere, at anytime, can investigate and uncover the mysteries and workings of the Universe simply by asking it the right questions in the right ways, listening to its answers, and putting the pieces together for themselves. Anyone can do it. Only, for various and sundry reasons, not everyone gets to do it. Some people don't have the economic ability, some don't have the sustained drive or interest, and some simply can't cut the mustard. But some people — some really, really good people — are driven from their passions for a sad, simple and completely unnecessary fact: that they were treated in unacceptable ways that they refused to just accept. And in a great many cases, that unacceptable treatment came simply because of their gender. Sexism sometimes looks like what you expect, and sometimes not. Here's one opinion on what we can all do about it to create the world we really want: where science really is for everyone. Read Replies (0)

writes: Last month, an elite team at IBM Research team announced an advance in quantum computing: it had built a four-qubit square lattice of superconducting qubits, roughly one-quarter-inch square, that was capable of detecting and measuring the two types of quantum computing errors (bit-flip and phase-flip). Previously, it was only possible to address one type of quantum error or the other. The next step is to correct quantum errors.
In a blog post, Mark Ritter, who oversees scientists and engineers at IBM's T.J. Watson Research Laboratory, wrote: "I believe we're entering what will come to be seen as the golden age of quantum computing research." His team, he said, is "on the forefront of efforts to create the first true quantum computer." But what would that mean, and what other big next steps are there?Read Replies (0)

Yesterday, in the intro to video number one of this two part extravaganza
we wrote, "The effects of light and dark on adults' Circadian rythym
has been studied over and over, but there hasn't been much research done on how light at night affects young children's sleep patterns."
Then we said, "This is the topic of Lameese Akacem's doctoral dissertation, and is a study being carried out under the aegis of the Sleep and Development Laboratory
at the University of Colorado, Boulder," and we mentioned that this research is (at least in part) crowdfunded
, and that the deadline for donating to this project is early next week, so if you feel this project is worth supporting you need to act within the next few days.Read Replies (0)

Actor Harry Shearer, perhaps best known as the voice of several characters on The Simpsons
, including that of Montgomery Burns, will be leaving the show's cast
, according to CNN.
Showrunner Al Jean said Shearer was "offered the same deal as the rest of the cast, but turned it down." ... Shearer is not just walking away from Springfield, but also a large sum of money. The actor was offered a guaranteed $14 million for two years of work, according to someone with direct knowledge of the matter. The proposed deal also allowed for him to do other projects if he wished."
That last part, though, seems to be in dispute, and central to Shearer's decision to leave; Shearer tweeted that it's because he "wanted what we've always had: the freedom to do other work
."Read Replies (0)
