So-called “strange metals” do not behave in ways typical to other metals when they are heated or cooled, deviating from the usual rules of physics.Scientists have discovered a new “strange metal” with a behaviour they do not seem to understand. The moment occurred when looking into bosonic systems, where such behaviour had not been spotted before.The new research was published in Nature on Wednesday, titled “Signatures of a strange metal in a bosonic system”. The scientists discovered a never-before-seen type of metal behaviour in the system, where an electrical charge is not carried by electrons, as usual, but by so-called Cooper pairs.Cooper pairs are bosons — particular kinds of subatomic particles. Electrons are fermions, another kind of such particles.
“We have these two fundamentally different types of particles whose behaviours converge around a mystery”, Jim Valles, a professor of physics at Brown and an author of the new study, said, as cited by The Independent. “What this says is that any theory to explain strange metal behaviour can’t be specific to either type of particle. It needs to be more fundamental than that”.The new research could open the door to solving a mystery that has been troubling scientists for almost three decades, since cuprates — a class of materials that tend to behave in ways different to other metals — were discovered.These “strange materials” do not appear to display the same characteristics as other other metals when they are heated. Normally, their resistance goes up until the point when it becomes constant. Cuprates, however, do not follow these rules, and scientists are still struggling to figure out why.
China’s “artificial sun” has set a new world record after superheating a loop of plasma to temperatures five times hotter than the sun for more than 17 minutes, state media reported.
The EAST (Experimental Advanced Superconducting Tokamak) nuclear fusion reactor maintained a temperature of 158 million degrees Fahrenheit (70 million degrees Celsius) for 1,056 seconds, according to the Xinhua News Agency. The achievement brings scientists a small yet significant step closer to the creation of a source of near-unlimited clean energy.
The Chinese experimental nuclear fusion reactor smashed the previous record, set by France’s Tore Supra tokamak in 2003, where plasma in a coiling loop remained at similar temperatures for 390 seconds. EAST had previously set another record in May 2021 by running for 101 seconds at an unprecedented 216 million F (120 million C). The core of the actual sun, by contrast, reaches temperatures of around 27 million F (15 million C).
There has been an unfortunate shift in Western educational practices in the past few decades away from what we used to call “critical thinking.” In fact, critical thinking was once a fundamental staple of US colleges and now it seems as though the concept doesn’t exist anymore; at least not in the way it used to. Instead, another brand of learning has arisen which promotes “right thinking”; a form of indoctrination which encourages and rewards a particular response from students that falls in line with ideology and not necessarily in line with reality.
It’s not that schools directly enforce a collectivist or corporatist ideology (sometimes they do), it’s more that they filter out alternative viewpoints as well as facts and evidence they do not like until all that is left is a single path and a single conclusion to any given problem. They teach students how to NOT think by presenting thought experiments and then controlling the acceptable outcomes.
For example, a common and manipulative thought experiment used in schools is to ask students to write an “analysis” on why people do not trust science or scientists these days. The trick is that the question is always presented with a built-in conclusion – That scientists should be trusted, and some people are refusing to listen, so let’s figure out why these people are so stupid.
I have seen this experiment numerous times, always presented in the same way. Not once have I ever seen a college professor or public school teacher ask students: “Should scientists today be trusted?”
Tardigrades are tiny organisms that can survive extreme environments including being chilled to near absolute zero. At these temperatures quantum effects such as entanglement become dominant, so perhaps it is not surprising that a team of physicists has used a chilled tardigrade to create an entangled qubit.
According to a preprint on the arXiv server, the team cooled a tardigrade to below 10 mK and then used it as the dielectric in a capacitor that itself was part of a superconducting transmon qubit. The team says that it then entangled the qubit – tardigrade and all – with another superconducting qubit. The team then warmed up the tardigrade and brought it back to life.
To me, the big question is whether the tardigrade was alive when it was entangled. My curiosity harks back to the now outdated idea that living organisms are “too warm and wet” to partake in quantum processes. Today, scientists believe that some biological processes such as magnetic navigation and perhaps even photosynthesis rely on quantum effects such as entanglement. So perhaps it is possible that the creature was alive and entangled at the same time.
In the preprint, the researchers say that the entangled tardigrade was in a latent state of life called cryptobiosis. They say they have shown that it is “possible to do a quantum and hence a chemical study of a system, without destroying its ability to function biologically”.
In December of 2017, researchers at MIT announced they had found a way to create light-emitting plants. They achieved this by embedding specialized nanoparticles into the leaves of watercress plants that allowed them to give off a very dim light for nearly four hours.
It was believed that with further optimization, these plants could one day be bright enough to illuminate a home or office.
Today, MIT engineers have upgraded their light-emitting plants to be able to be charged by a LED in just 10 seconds, glow 10 times brighter than their first generation of plants, and last for several minutes. They can even be recharged repeatedly.
The specialized nanoparticles contain the enzyme luciferase, a substance found in light-emitting fireflies. This process is an example of the emerging field of “plant nano-bionics,” wherein researchers develop ways to augment plants with novel features.
In order to make their plants glow longer, MIT created and used a “light capacitor,” which is normally the part of an electrical circuit that can store photons and release them when needed.
The researchers showed that after 10 seconds of blue LED exposure, their plants could emit light for about an hour. The light was brightest for the first five minutes and then gradually diminished. The plants can be continually recharged for at least two weeks.
To hear the way some politicians talk, when it comes to COVID-19, they’re all “Following the Science,” not to mention “the Data.”
“Look at the data. Follow the science. Listen to the experts. Be smart,” now-former New York Gov. Andrew Cuomo wrote on Twitter in May 2020, after “Two Weeks to Flatten the Curve” had fully transitioned to “The New Normal.”
“We’ve been operating on facts and data and science from the very beginning,” said Illinois Gov. J.B. Pritzker in a campaign ad titled simply “Follow The Science.”
President Joe Biden has frequently appealed to “the Science.” In an executive order announcing a vaccine mandate for federal workers, for instance, he said his administration used “the best available data and science-based public health measures.” In an article criticizing Biden’s move to push vaccine boosters in September of this year, StatNews’s Lev Facher described “Follow the Science” as “a mantra” for the administration.
China’s state-run Global Times newspaper celebrated on Thursday the alleged discovery of a scientific process to create a “humanized pig” more susceptible to severe Chinese coronavirus cases, which scientists could infect and use for research.
The propaganda outlet attributed the scientific achievement to the Institute of Microbiology of the Chinese Academy of Sciences (IMCAS). The CAS, a research institution, is the world’s largest organization of its kind and a formal arm of the Chinese government. The Times published an illustrative figure on the development of “humanized” pigs that appears to have first surfaced in a study published in August that promoted the use of genetically modified pigs for Chinese coronavirus research based on how rapidly scientists could generate them and their heightened similarities with the human body.
The August study – published in Cell Discovery, a journal sponsored by the CAS, revealed that Chinese scientists had attempted to use CRISPR gene-editing technology to remove the genetic protective shields that make Chinese coronavirus not a significant threat to most pigs. CRISPR technology became the source of global controversy in 2018 after a Chinese scientist, He Jiankui, claimed to have used the method to genetically modify unborn baby twins to make them immune to HIV. The Communist Party sentenced He to three years in prison for conducting the human experiment without the full approval of the Party.
