For the First Time in 200 Years, a New Blue Pigment Is Up for Sale

Researchers discovered YInMn Blue in 2009. Now, you can purchase a tiny tube of the bright blue paint for $179.40 In 2009, researchers at Oregon State University discovered YInMn Blue—the first new blue pigment identified in 200 years—while developing materials for use in electronics. Led by chemist Mas Subramanian, the team quickly realized that it had stumbled onto something significant. “People have been looking for a good, durable blue color for a couple of centuries," Subramanian told NPR’s Gabriel Rosenberg in 2016. Eleven years later, in May 2020, the United States Environmental Protection Agency (EPA) officially approved the punchy pigment, which is far more vivid than cobalt or Prussian blue, for commercial use, as Coatings World reported at the time. The government agency approved YInMn for use in industrial coatings and plastics in September 2017, but because testing for consumer use is far more rigorous, commercial paint manufacturers and artists alike faced a far longer wait. (To help color enthusiasts cope with the delay, Crayola introduced Bluetiful, a crayon inspired by the pigment, that same year.) “We had to tell many artists we could not sell them the material and would let them know as soon as we could,” Jodi L. O’Dell, head of community relations at Golden Artist Colors, tells Artnet News’ Sarah Cascone. Now that the EPA has given its stamp of approval, the pigment is finally available for commercial use, with paint retailers such as Kremer Pigmente in Germany and Golden in the U.S. offering YInMn Blue products. A dry powder version has yet to be approved for public consumption. Mark Ryan, a marketing manager for the Shepherd Color Company, a pigment manufacturing business that obtained a license to sell YInMn in 2016, tells Artnet News that “[t]he art world likes it because of the color.” Industrial companies, meanwhile, like “it because of what it can do in terms of environmental regulations for building products.” (The pigment reflects most infrared radiation, keeping it, and by extension the building exteriors it adorns, cool.) https://www.smithsonianmag.com/smart-ne ... 180976769/ TED talk by the discoverer: Rob Lister Posts: 23535 Joined: Sun Jul 18, 2004 7:15 pm Title: Incipient toppler Location: Swimming in Lake Ed ### Re: Amusing Science That's pretty cool.

A small contingent of the world’s population carries a mutation that makes them immune to the odious funk that wafts off fish, according to a study of some 11,000 people published Thursday in the journal Current Biology. The trait is rare, but potent: When faced with a synthetic odor that would put many people off their lunch, some test subjects smelled only the pleasant aroma of caramel, potato or rose. The vast majority of people aren’t so lucky. Nearly 98 percent of Icelanders, the research said, are probably as put off by the scent as you’d expect. The mutation is thought to be even rarer in populations in other countries. “I can assure you I do not have this mutation,” said Dr. Kári Stefánsson, a neurologist and the study’s senior author. “I tend to get nauseated when I get close to fish that is not completely fresh.” Dr. Stefánsson is the founder and chief executive of deCODE genetics, a biopharmaceutical company in Iceland’s capital, Reykjavik, which has been parsing the human genome for several decades. The team’s latest caper involved a deep dive into the underappreciated sense of olfaction. Study participants were asked to take a whiff of six Sniffin’ Sticks — pens imbued with synthetic odors resembling the recognizable scents of cinnamon, peppermint, banana, licorice, lemon and fish. They were asked to identify the smell, then rate its intensity and pleasantness. The older the study subjects were, the more they struggled to accurately pinpoint the scents. That’s unsurprising, given that sensory functions tend to decline later in life, said Rósa Gísladóttir, the study’s lead author. But even younger people didn’t always hit the mark, she said. The lemon and banana sticks, for instance, prompted descriptions of gummy bears and other candy-sweet smells. The reek of fish, however, was mostly recognizable and received by far the lowest pleasantness ratings among the six sticks. But a small group of people consistently tolerated or even welcomed the piscine perfume: those born with a genetic mutation that incapacitated a gene called TAAR5. TAAR5 helps make a protein that recognizes a chemical called trimethylamine, or TMA, that is found in rotten and fermented fish and certain animal bodily fluids, including human sweat and urine. https://www.nytimes.com/2020/10/08/scie ... genes.html Witness Posts: 35689 Joined: Thu Sep 19, 2013 5:50 pm ### Re: Amusing Science https://old.reddit.com/r/powerwashingpo ... wednesday/ robinson Posts: 19272 Joined: Sat Aug 12, 2006 2:01 am Title: Je suis devenu Français Location: USA ### Re: Amusing Science https://twitter.com/robmeekel/status/13 ... 92998?s=21 Witness Posts: 35689 Joined: Thu Sep 19, 2013 5:50 pm ### Re: Amusing Science “Blessed by the algorithm”: Theistic conceptions of artificial intelligence in online discourse Abstract “My first long haul flight that didn’t fill up and an empty row for me. I have been blessed by the algorithm ”. The phrase ‘blessed by the algorithm’ expresses the feeling of having been fortunate in what appears on your feed on various social media platforms, or in the success or virality of your content as a creator, or in what gig economy jobs you are offered. However, we can also place it within wider public discourse employing theistic conceptions of AI. Building on anthropological fieldwork into the ‘entanglements of AI and Religion’ (Singler 2017a), this article will explore how ‘blessed by the algorithm’ tweets are indicative of the impact of theistic AI narratives: modes of thinking about AI in an implicitly religious way. This thinking also represents continuities that push back against the secularisation thesis and other grand narratives of disenchantment that claim secularity occurs because of technological and intellectual progress. This article will also explore new religious movements, where theistic conceptions of AI entangle technological aspirations with religious ones. https://link.springer.com/article/10.10 ... 20-00968-2 (full text).

So the outgoing ball (or nail) at each stage goes faster than the incoming one. It's not free energy because you put lots of energy into the system when you pull the balls off the incoming side of the magnets when you reload the gun for its next shot. robinson Posts: 19272 Joined: Sat Aug 12, 2006 2:01 am Title: Je suis devenu Français Location: USA ### Re: Amusing Science The kinetic energy of the first ball is transferred to the last ball, which is why it moves, but to understand why the ball accelerated you have to think about the poles of the magnets The very strong magnets are clamped down or they would all move, very fast towards each other So that third ball is already strongly attracted to the next magnet, when it moves it is already wanting to go towards the next set of magnets, because it is magnetized already That’s why it escapes so easily, and each collision has more force, because of the nature of magnets It helps to realize each set of clamped down magnets are already trying to slam together The ball bearing is like a small piece of the magnet breaking free robinson Posts: 19272 Joined: Sat Aug 12, 2006 2:01 am Title: Je suis devenu Français Location: USA ### Re: Amusing Science Watch the 2nd ball bearing, which also moves towards the next magnet The third ball bearing is barely holding on when the energy is transferred to it Witness Posts: 35689 Joined: Thu Sep 19, 2013 5:50 pm ### Re: Amusing Science I doubt it qualifies as science, but it's amusing: Scientists Played Music to Cheese as It Aged. Hip-Hop Produced the Funkiest Flavor Researchers played nonstop loops of Led Zeppelin, A Tribe Called Quest and Mozart to cheese wheels to find out how sound waves impacted flavor The creation of good cheese involves a complex dance between milk and bacteria. In a quite literal sense, playing the right tune while this dance unfolds changes the final product’s taste, a new study shows. Denis Balibouse and Cecile Mantovani at Reuters report that hip-hop, for example, gave the cheese an especially funky flavor, while cheese that rocked out to Led Zeppelin or relaxed with Mozart had milder zests. Last September, Swiss cheesemaker Beat Wampfler and a team of researchers from the Bern University of Arts placed nine 22-pound wheels of Emmental cheese in individual wooden crates in Wampfler’s cheese cellar. Then, for the next six months each cheese was exposed to an endless, 24-hour loop of one song using a mini-transducer, which directed the sound waves directly into the cheese wheels. The “classical” cheese mellowed to the sounds of Mozart’s The Magic Flute. The “rock” cheese listened to Led Zeppelin’s “Stairway to Heaven.” An ambient cheese listened to Yello’s “Monolith,” the hip-hop cheese was exposed to A Tribe Called Quest’s “Jazz (We’ve Got)” and the techno fromage raved to Vril’s “UV.” A control cheese aged in silence, while three other wheels were exposed to simple high, medium and low frequency tones. According to a press release, the cheese was then examined by food technologists from the ZHAW Food Perception Research Group, which concluded that the cheese exposed to music had a milder flavor compared to the non-musical cheese. They also found that the hip-hop cheese had a stronger aroma and stronger flavor than other samples. The cheeses were then sampled by a jury of culinary experts during two rounds of a blind taste test. Their results were similar to the research group’s conclusions and the hip-hop cheese came out on top. ... Wampfler also tells the AFP that he can see marketing cheeses based on the music they matured too. Already, he says people have called requesting cheese that has listened to the blues, Balkan music and ACDC. [Of course.] https://www.smithsonianmag.com/smart-ne ...

But in a new study, University of Copenhagen researchers tested a model which suggests that the universe’s expansion is due to a dark substance with a kind of magnetic force. Should the model stand, it means that dark energy simply doesn’t exist, according to the UCPH professor behind the study. Until now, researchers have believed that dark energy accounted for nearly 70 percent of the ever-accelerating, expanding universe. For many years, this mechanism has been associated with the so-called cosmological constant, developed by Einstein in 1917, that refers to an unknown repellant cosmic power. But because the cosmological constant—known as dark energy—cannot be measured directly, numerous researchers, including Einstein, have doubted its existence—without being able to suggest a viable alternative. Until now. In a new study by researchers at the University of Copenhagen, a model was tested that replaces dark energy with a dark matter in the form of magnetic forces. “If what we discovered is accurate, it would upend our belief that what we thought made up 70 percent of the universe does not actually exist. We have removed dark energy from the equation and added in a few more properties for dark matter. This appears to have the same effect upon the universe’s expansion as dark energy,” explains Steen Harle Hansen, an associate professor at the Niels Bohr Institute’s DARK Cosmology Centre. The universe expands no differently without dark energy The usual understanding of how the universe’s energy is distributed is that it consists of five percent normal matter, 25 percent dark matter and 70 percent dark energy. In the UCPH researchers’ new model, the 25 percent share of dark matter is accorded special qualities that make the 70 percent of dark energy redundant. “We don’t know much about dark matter other than that it is a heavy and slow particle. But then we wondered—what if dark matter had some quality that was analogous to magnetism in it? We know that as normal particles move around, they create magnetism. And, magnets attract or repel other magnets—so what if that’s what’s going on in the universe? That this constant expansion of dark matter is occurring thanks to some sort of magnetic force?” asks Steen Hansen. https://www.science.ku.dk/english/press ... -universe/ for the rest.

Piping an oxygen-rich liquid through the anus could be a life-saver. A new treatment for failing lungs that involves such a process has been successfully tested in pigs.

People with low blood oxygen levels may be treated in intensive care by being put on a ventilator, which blows air into their lungs. But this usually requires sedation and can injure delicate lung tissue. “It can be really damaging,” says Takanori Takebe at the Tokyo Medical and Dental University.

Takebe wondered if people could absorb oxygen through their intestines, which happens in some freshwater fish. In mammals, the rectum is lined with a thin membrane that allows absorption of certain compounds into the bloodstream, and doctors already exploit this by giving some medicines as suppositories.

The measurement of partisan sorting for 180 million voters

Abstract

Segregation across social groups is an enduring feature of nearly all human societies and is associated with numerous social maladies. In many countries, reports of growing geographic political polarization raise concerns about the stability of democratic governance. Here, using advances in spatial data computation, we measure individual partisan segregation by calculating the local residential segregation of every registered voter in the United States, creating a spatially weighted measure for more than 180 million individuals. With these data, we present evidence of extensive partisan segregation in the country. A large proportion of voters live with virtually no exposure to voters from the other party in their residential environment. Such high levels of partisan isolation can be found across a range of places and densities and are distinct from racial and ethnic segregation. Moreover, Democrats and Republicans living in the same city, or even the same neighbourhood, are segregated by party.

100 million times magnification. (That's a new record, btw.) Enough to see individual atoms and their orientations:

Incredible Microscope Sees Atoms at Record Resolution

https://scitechdaily.com/images/Electro ... 77x437.jpg
This image shows an electron ptychographic reconstruction of a praseodymium orthoscandate (PrScO3) crystal, zoomed in 100 million times. Credit: Cornell University
In 2018, Cornell researchers built a high-powered detector that, in combination with an algorithm-driven process called ptychography, set a world record by tripling the resolution of a state-of-the-art electron microscope.

As successful as it was, that approach had a weakness. It only worked with ultrathin samples that were a few atoms thick. Anything thicker would cause the electrons to scatter in ways that could not be disentangled.

Now a team, again led by David Muller, the Samuel B. Eckert Professor of Engineering, has bested its own record by a factor of two with an electron microscope pixel array detector (EMPAD) that incorporates even more sophisticated 3D reconstruction algorithms.

The resolution is so fine-tuned, the only blurring that remains is the thermal jiggling of the atoms themselves.

The group’s paper, “Electron Ptychography Achieves Atomic-Resolution Limits Set by Lattice Vibrations,” published May 20 in Science. The paper’s lead author is postdoctoral researcher Zhen Chen.

“This doesn’t just set a new record,” Muller said. “It’s reached a regime which is effectively going to be an ultimate limit for resolution. We basically can now figure out where the atoms are in a very easy way. This opens up a whole lot of new measurement possibilities of things we’ve wanted to do for a very long time. It also solves a long-standing problem – undoing the multiple scattering of the beam in the sample, which Hans Bethe laid out in 1928 – that has blocked us from doing this in the past.”

Ptychography works by scanning overlapping scattering patterns from a material sample and looking for changes in the overlapping region.

“We’re chasing speckle patterns that look a lot like those laser-pointer patterns that cats are equally fascinated by,” Muller said. “By seeing how the pattern changes, we are able to compute the shape of the object that caused the pattern.”

The detector is slightly defocused, blurring the beam, in order to capture the widest range of data possible. This data is then reconstructed via complex algorithms, resulting in an ultraprecise image with picometer (one-trillionth of a meter) precision.

“With these new algorithms, we’re now able to correct for all the blurring of our microscope to the point that the largest blurring factor we have left is the fact that the atoms themselves are wobbling, because that’s what happens to atoms at finite temperature,” Muller said. “When we talk about temperature, what we’re actually measuring is the average speed of how much the atoms are jiggling.”
