    I heard yesterday, maybe on RN, that the greatest radiation is being emitted from AM radio stations??? so that is where you get it...

    Exoplanets

    Water Discovered in the Atmosphere of an Exoplanet in the Habitable zone. It Might Be Rain

    Astronomers using the Hubble space telescope have discovered water in the atmosphere of an exoplanet in its star’s habitable zone. If confirmed, it will be the first time we’ve detected water—a critical ingredient for life as we know it—on an exoplanet. The water was detected as vapour in the atmosphere, but the temperature of the planet means it could sustain liquid water on its surface, if it’s rocky.

    The planet is called K2-18b, and it’s about 110 light years away. The planet is much different than Earth. It’s a Super-Earth, and it’s twice as large as Earth, and about 8 times as massive. K2-18b is orbiting a red dwarf star, and it was first discovered in 2015 by the Kepler Space Telescope. ...

    Just as chess can be described as a brilliant waste of time space travel/exploration can be described as a brilliant waste of money.

    Speaking of wasting money - without the brilliance: "Other successful motions included support for a national watchdog to verify scientific papers that are used in government policy making. Queensland MP George Christensen, who sponsored the motion, said he was concerned by researchers pushing "left wing causes"."

    Obviously this is not going to go anywhere, but the idea is just idiotic. Firstly, there is already a check on scientific papers - it's called peer review. Secondly, how exactly would papers be 'verified'? And who would do the 'verification'?

    It's human nature, to go wherever man has never gone before

    As Jodi Foster says in Contact, if there's nothing out there, it seems like an awful waste of space

    In earlier times man was driven by survival needs to explore but what possible use could water be a million miles away? We know that only a fraction of the expenditure on armaments and defence could "solve" the world's problems. Space expenditure fits into the same category. Of course there are side benefits but they are only minimal in comparison to the money spent. North Korean people are starving whilst their leaders cheer rockets and bombs - how sickening! That is WW2 mentality not Bertrand Russell post war enlightenment reaction.

    Columbus didn't sail across the Atlantic for survival. He was an explorer, for its own sake.

    Finding an exoplanet in the habitable temperature-range distance from its sun (the Goldilocks zone) with atmospheric water vapour, and maybe surface water, is a major discovery. That's one of the prerequisites for life as we know it. It's not of any possible use 110 light years away, but that's not the point. It's adding to the store of human knowledge.

    I know we can say that too many people should not have been born so it is not scientists' fault and their scientific funding should not be denied to feed the starving masses but it is callous and inhumane. I only seen on SBS program on Hitler last night how his exploits for WW2 was based on more land for Germans. Scientists were responsible for the vaccinations etc that kept too many children alive (terrible to say) and Capa Fan's argument is that that they are doing a fantastic job with science of feeding all those extra mouths (and souls) but we also know how the biosphere is virtually on it's last legs in trying to remain viable. The forests burning in Asia and south America etc etc. - all for more resources. Now super typhoons due to climate change probably, parts of the Bahamas wiped out. Central Philippines wiped out about 6 years ago in a similar fashion. Nothing has changed since Albert Einstein pronounced that the splitting of the atom has changed everything except our mode of thinking. That atom is a symbol of the whole industrialised and de-natured world. And just to prove the point that saying of Einstein is not included in his 30 greatest quotes.

    Measles even more dangerous: damages immune system, so anti-vaxers are even sillier

    Measles wipes out immune system's memory, study finds
    Scientists say threat posed by measles is ‘much greater than we previously imagined’
    Hannah Devlin, Science correspondent, Guardian, 31 Oct 2019

    Measles causes long-term damage to the immune system, leaving children who have had it vulnerable to other infections long after the initial illness has passed, research has revealed.

    Two studies of unvaccinated children in an Orthodox Protestant community in the Netherlands found that measles wipes out the immune system’s memory of previous illnesses, returning it to a more baby-like state, and also leaves the body less equipped to fight off new infections.

    Measles eliminated between 11% and 73% of children’s protective antibodies, the research found.

    “We’ve found really strong evidence that the measles virus is actually destroying the immune system,” said Prof Stephen Elledge, a geneticist at Harvard Medical School and co-author of one of the papers. “The threat measles poses to people is much greater than we previously imagined.”
    “The history of the 20th century is full of examples of countries that set out to redistribute wealth and ended up redistributing poverty.”

Any system which allows some people to exercise unbridled power over others is an open invitation to abuse, whether that system is called slavery or socialism or something else.”—Thomas Sowell

    The Greatest Comeback since Lazarus?

    Eastern Australian Humpback. 70 years ago there were 150 survivors, on the brink of extinction. Last September I was privileged to spend a week on the water off Airlie Beach working with scientists studying migrating EAH.

    Most whales in 70 years but 40,000 humpbacks 'close to capacity' say experts

    Whale sharks, the largest of all living fish, have literal eye teeth

    Whale Sharks Have Eyeballs Covered in Tiny Teeth
    George Dvorsky, Gizmodo, 1 July 2020

    Marine biologists from Japan say whale sharks have eyeballs coated in tiny teeth, in a discovery unique to this hulking but gentle aquatic species.

    Eye teeth are typically used to describe our upper canines, but new research published in PLOS One describes eye teeth of a literal sort.

    Marine biologists from Japan’s Okinawa Churashima Research Centre have found that whale sharks have eyes covered in dermal denticles, or modified teeth. These tiny structures represent a previously unknown form of eye protection, serving as a kind of armour to protect against the elements, according to the new research.

    Whale sharks are the largest of the sharks, growing as long as 59 feet (18 meters).* These behemoths are harmless to humans, feeding primarily on plankton and the occasional fish.

    Whale sharks, unlike some other shark species, don’t have eyelids. Also, their tiny eyes are located at the corners of their square heads, exposing their peepers to potential damage. That’s where the protective eye denticles come in.

    7 Scientific Urban Legends Debunked!

    Several things that are thought to be scientific common knowledge are not. One is that bacteria in our bodies outnumber the human cells 10:1. The right ratio is closer to 1:1.

    Another one is that people should drink eight glasses of water every day. Size of glass and adjustment for body mass are not specified. But this came from a back-of-the-envelop calculation, and the original source said that most people get a lot of that daily water requirement from food.

    Unfortunately, the legend travels faster and further than the refutation.

    Interesting, as chance would have it, I started reading Bill Bryson’s book The Body: A Guide for Occupants this weekend. Chapter 2 Microbial Me covered the same topic and agreed with the 1:1 ratio as per the video.

    Cryo–electron microscopy breaks the atomic resolution barrier at last
    By Robert F. Service, Science, 21 Oct 2020

    If you want to map the tiniest parts of a protein, you only have a few options: You can coax millions of individual protein molecules to align into crystals and analyze them using x-ray crystallography. Or you can flash-freeze copies of the protein and bombard them with electrons, a lower resolution method called cryo–electron microscopy (cryo-EM). Now, for the first time, scientists have sharpened cryo-EM’s resolution to the atomic level, allowing them to pinpoint the positions of individual atoms in a variety of proteins at a resolution that rivals x-ray crystallography’s.

    “This is just amazing,” says Melanie Ohi, a cryo-EM expert at the University of Michigan, Ann Arbor. “To see this level of detail, it’s just beautiful.” Because the heightened resolution reveals exactly how complex cellular machines carry out their jobs, improvements in cryo-EM should yield countless new insights into biology.

    To map protein structures, scientists have been using x-ray crystallography since the late 1950s. By bombarding crystallized proteins with x-rays and analyzing the way the x-rays ricochet off, scientists can work out a protein’s likely makeup and shape. Decades of improvements to the x-ray beams, detectors, and computer power have made the approach fast and accurate. But the approach doesn’t work well when proteins are exceptionally large, work in complexes such as the ribosome, or can’t be crystallized, as is the case with many proteins that sit in cell membranes.

    In contrast, researchers using cryo-EM fire electrons at copies of frozen proteins that need not be crystallized; detectors record the electrons’ deflections, and sophisticated software stitches the images together to work out the proteins’ makeup and shape. Researchers in Japan had previously shown they could narrow the resolution to 1.54 angstroms—not quite reaching the point where they could distinguish individual atoms—in a gut protein called apoferritin, which binds and stores iron. Now, with the help of improvements in electron beam technology, detectors, and software, two groups of researchers—from the United Kingdom and Germany—have narrowed that to 1.25 angstroms or better, sharp enough to work out the position of individual atoms, they report today in Nature.
