More affordable magnets and tech advances have the fusion community hoping for (economically viable) net positive output by the 2030s. Here's an overview of what's going on in fusion research, from the Washington Post (non paywall version is the second link): https://www.washingtonpost.com/technology/2022/08/26/nuclear-fusion-technology-climate-change/ https://archive.ph/3L8wC

🤑 https://www.msn.com/en-us/health/medical/thousands-of-new-viruses-discovered-in-the-ocean/ar-AAW4bRV?ocid=mmx&PC=EMMX01 Just saw this, thousands of viruses have been discovered in the ocean that were never known to man before the conclusion of some study. Turns out that this is actually quite significant, and scientists are even considering doubling the amount of phyla classifications in biology, and phyla are just beneath kingdom if you weren't aware... Researchers have already found one that is in a new phyla, and it is believed to be a significant part of the ecosystem on Earth due to being all over the oceans Now I would be in stitches o…

Thought this was fascinating. An AI program developed at Columbia University observes video footage and calculates the dynamics of the system from the ground up i.e it creates variables to model the system. Although the researchers understand some of the variables that have been implemented e.g angular calculations for a pendulum, the rest remains a mystery, it works, but they don't know why it works. https://scitechdaily.com/artificial-intelligence-discovers-alternative-physics/

The DNA code can have changes in it called mutations. DNA sequences specifically codes for amino acid sequences which are built into proteins. Proteins control the development of organisms from a starting point to final organism itself. If the DNA mutations are in areas of the DNA code which can cause changes in the amino acid sequence, the final protein could be faulty and affect the final organism. Diseases such as Sickle cell anaemia or cystic fibrosis are caused by a harmful DNA mutation arising from a single letter change in the DNA sequence. I have grown up, and taught to my A-level (K12/13) students that some DNA mutations which do not affect the ami…

On June 29, the Earth unexpectedly made a revolution around the axis 1.59 ms faster than 24 hours, and this became its fastest revolution since atomic clocks began tracking such data with great accuracy in the 1960s. In recent years, the Earth's rotation has been gradually accelerating, but no one knows why this is happening. Since 2020, the planet has already broken the rotation speed record a couple dozen times, despite the fact that nothing like this had happened for decades before. The Earth is not a perfect ball, so its rotation is constantly fluctuating, being subject to a variety of factors, including its internal structure, the tidal effect of the Moon, climat…

Knowledge overconfidence is associated with anti-consensus views on controversial scientific issues https://www.science.org/doi/10.1126/sciadv.abo0038 Recently, evidence has emerged, suggesting a potentially important revision to models of the relationship between knowledge and anti-science attitudes: Those with the most extreme anti-consensus views may be the least likely to apprehend the gaps in their knowledge Probably comes as no surprise to folks here, encountering people with “alternative” views on science. Mismatches between what individuals actually know (“objective knowledge”) and subjective knowledge are not uncommon (31). People tend to be …

https://www.npr.org/2022/07/27/1114074697/james-lovelock-gaia-theory-dies LONDON — James Lovelock, the British environmental scientist whose influential Gaia theory sees the Earth as a living organism gravely imperiled by human activity, has died on his 103rd birthday. Lovelock's family said Wednesday that he died the previous evening at his home in southwest England "surrounded by his family." The family said his health had deteriorated after a bad fall but that until six months ago Lovelock "was still able to walk along the coast near his home in Dorset and take part in interviews." Born in 1919 and raised in London, Lovelock studied chemistry, medicine a…

About (data from frey and detterman, 2004): reference what would explain in figure C an evaluator close to IQ 90 with an evaluation of 1300 on the SAT? Is IQ very relative, where we can't reduce someone's aptitude on a test?

"...while attempting to study genetic differences between plants in a massive undersea [Australian] meadow, their samples revealed that the "meadow" was in fact just one very old — and very large — organism." It is estimated to cover 77 square miles, is about 4,500 years old, a strange hybrid ribbon weed, that kept all chromosomes from both mother and father.

This is not surprising news, as species location boundaries have always moved with changing climate. However it is good news, especially if Man looks after the new areas as suggested in the article.

I've just stumbled upon this new paper draft, [2205.07921] The Futility of Exoplanet Biosignatures (arxiv.org) and immediately thought of @beecee because of this statement in the abstract: Technical constraints and our limited access to other worlds suggest we are more likely to detect an out-of-equilibrium suite of gasses than a writhing octopus. Yet, anything short of a writhing octopus will raise skepticism among astrobiologists about what has been detected.

Carbon. It takes a hundred suns to die before your magic web extends. But once it does, a world of possibilities is revealed. Your opening act is: "Let there be life". Not quite satisfied with this, you make things that make things that bring about: The hardest substance (diamond) The best lubricant (graphite). The best thermal conductor (graphene). Is there an end to this magic? If the Ancient Greeks had only suspected your capital importance, they would have named a god in your honour. Sorry, I got carried away with carbon love.

"The expansion rate of the universe was predicted to be slower than what Hubble actually sees. By combining the Standard Cosmological Model of the Universe and measurements by the European Space Agency's Planck mission (which observed the relic cosmic microwave background from 13.8 billion years ago), astronomers predict a lower value for the Hubble constant: 67.5 plus or minus 0.5 kilometers per second per megaparsec, compared to the SH0ES team's estimate of 73. Given the large Hubble sample size, there is only a one-in-a-million chance astronomers are wrong due to an unlucky draw, said Riess, a common threshold for taking a problem seriously in physics.
