^I just read SEVENEVES by Neal Stephenson, and a large portion of it hinges upon robot swarms. It was a really ingenious and optimistic take on them though.



Michael Pollan narrates some time lapse video of plants growing. He -- as he usually does -- makes the plants sympathetic and human. I'm thinking about playing the video for my students, first silent and then with his narration, to demonstrate how language colors perception

I loved it. Like a lot of Stephenson, it falls apart in the third act, but there are some craaazy ideas built on current tech/understanding of orbital physics. $17 seems like a lot. You could probably find a used edition for cheaper...or check it out from your local library. Maybe check Google Play/iBooks/Nook store and price shop?

Directing Magnetic Energy Into The Brain Can Reduce Belief In God, Prejudice Toward Immigrants

WTH???

Quote :
"It sounds like a joke — but a new study out of the University of York in the UK finds that directing magnetic energy into the brain can change a person’s beliefs in God, as well as reduce their prejudice against immigrants.

Scientists from both the University of York and the University of California, Los Angeles (UCLA) tinkered with participants’ brains using magnetic energy, hoping to see whether certain brain regions were linked to ideology — such as feelings about religion and nationalism."

Anybody know this experimental EM Drive engine for rockets? So first it was considered a joke, then scientists took it seriously, and apparently now NASA has confirmed it works, but no one still knows why.

If they can make it work for space flight, travel times will supposedly be reduced to 10-20% of current times.

Quote :
"Last summer WIRED revealed that Nasa's Eagleworks Lab was testing a copy of the EmDrive, a propulsion device frequently labelled as "impossible" because it appears to violate the law of conservation of momentum. Against all expectation they found it produced thrust. The response from the scientific community was dramatic, and generally sceptical -- but the "anomalous thrust" stubbornly refuses to disappear as more research zeroes in on it."

i would say that "Nasa confirmed it works" is more of a clickbait headline than actual facts on the ground. I'm a member of the NASA Spaceflight website and i've been keeping up with it... still a bunch of tinkering and trying to figure out what's going on. the amount of "thrust" produced so far has been minuscule (on the same order as measurement errors) and the amount of energy put into it multiple orders of magnitude higher than the resulting energy from the "thrust"

that being said i'm not saying it shouldn't be explored. if anything maybe we get some new understanding of the nature of the universe... one idea is that virtual particles that have been predicted are where the momentum is coming from... somehow the field is pushing against those, but again, this is just guesswork (not even to the level of a hypothesis yet)

edit: And no, i don't claim to understand all of the physics involved, but i've read that any potential thrust measured also is not any more significant than the pressure of photons that could be generated leaving the assembly.

"Between the years of 1969 and 1972 the human race accomplished arguably the single greatest technological achievement of all time, when humans first set foot on another celestial body.
This short film is a tribute to the NASA Apollo Program space missions which successfully landed 12 men on the Moon. It was created entirely from still images from the Project Apollo Archive, which has bought together scans of all the original unprocessed images taken by the crews of the Apollo 10 to 17 space missions."

By removing the protein galectin-3 (Gal3), a team of investigators led by University of California School of Medicine researchers were able to reverse diabetic insulin resistance and glucose intolerance in mouse models of obesity and diabetes.

By binding to insulin receptors on cells, Gal3 prevents insulin from attaching to the receptors resulting in cellular insulin resistance. The team led by Jerrold Olefsky, MD, professor of medicine in the Division of Endocrinology and Metabolism at UC San Diego School of Medicine, showed that by genetically removing Gal3 or using pharmaceutical inhibitors to target it, insulin sensitivity and glucose tolerance could be returned to normal, even among older mice. However, obesity remained unchanged.

"This study puts Gal3 on the map for insulin resistance and diabetes in mouse model," said Olefsky, associate dean for scientific affairs and senior author of the study. "Our findings suggest that Gal3 inhibition in people could be an effective anti-diabetic approach."

Olefsky and other researchers have been studying how chronic tissue inflammation leads to insulin resistance in type 2 diabetes. In the paper, published in the journal Cell on November 3, researchers explain that inflammation requires macrophages -- specialized cells that destroy targeted cells. In obese adipose tissue (fat), for example, 40 percent of cells are macrophages. Macrophages in turn secrete Gal3, which then acts as a signaling protein attracting more macrophages, thus resulting in the production of even more Gal3.

Furthermore, investigators identified bone marrow-derived macrophages as the source of Gal3 that leads to insulin resistance. More importantly, researchers found that Gal3 is secreted by macrophages, and can then cause insulin resistance in liver, fat cells, and muscle cells independent of inflammation.

Gal3 has previously been connected to other diseases. Olefsky will continue to study Gal3 depletion as a possible therapeutic target for nonalcoholic steatohepatitis as well as heart and liver fibrosis.

^ That's great, but I am afraid if it is somehow made into a cure one day, it will make people think they can continue eating like shit because they won't get diabetes anymore!

Diabetes can be easily reversed using diet in a matter of weeks by eating a diet of only whole plant foods, but people always want a silver bullet while continuing to eat crap.

"Algorithm that increases the resolution of images, synthesizing additional details as needed based on its understanding of what e.g. human faces should look like. Left is an 8x8 input, middle is the enhanced 32x32 version, right is what the 8x8 input originally looked like at 32x32 size.

To clarify, the algorithm isn't really "reconstructing" the original 32x32 image: there isn't enough information available for that. The algorithm is more like an artist that's given a sketch to use for inspiration, and then fills in the details using their imagination and sense of what would look good."

i do not know of the tool you speak of, but this is trying to get at/guess an existing face.

so if there is blurry pics/footage of criminals, this can guess what they look like so they can be easier to find.
