I just finish watching a series doco [in 4 parts] and would recommend it's viewing. Describing it in a word? Scary......Í can't say how close it is to the actual truth but you can gauge that for yourself.........

According to this TIME article, "Two companies, Editas Medicine and Allergan, will test this [method] in up to 18 people around the United States" afflicted with a form of congenital blindness called Leber congenital amaurosis where sufferers may "see only bright lights and blurry shapes and can eventually lose all sight." It seems promising and reminds me somewhat of a scene from one of those Star Trek movies where the Enterprise travels back in time and Dr. McCoy encounters a patient who he gives a pill that regenerates her liver...or was it her kidney?.

https://phys.org/news/2019-07-space-kits-blast-orbit.html Space mining kits blast off for tests in orbit: Astronauts are to test the world's first space mining devices, in an advance that could open up a new frontier in exploring the universe. Prototype kits are being sent to the International Space Station to study how microscopic organisms could be used to recover minerals and metals from space rocks. The groundbreaking study could aid efforts to establish manned settlements on distant worlds by helping develop ways to source minerals essential for survival in space. Tests will reveal how low gravity affects bacteria's natural ability to extract…

...despite the headline saying they did https://time.com/4854718/quantum-entanglement-teleport-space/? Some stories say they teleported an electron. This one says photon. Regardless, it was the state of the particle that was teleported, not the particle itself.

„This particular photo shows entanglement between two photons - two particles of light. They're interacting and for a brief moment sharing physical states. Paul-Antoine Moreau, first author on the paper where the image was unveiled, told the BBC the image was "an elegant demonstration of a fundamental property of nature". To capture the incredible photo, Moreau and a team of physicists created a system that blasted out streams of entangled photons at what they described as 'non-conventional objects'. The experiment actually involved capturing four images of the photons under four different phase transitions. https://www.sciencealert.com/scientists-just…

https://phys.org/news/2019-07-japan-hayabusa2-probe-touchdown-asteroid.html Japan's Hayabusa2 probe makes 'perfect' touchdown on asteroid: Japan's Hayabusa2 probe made a "perfect" touchdown Thursday on a distant asteroid, collecting samples from beneath the surface in an unprecedented mission that could shed light on the origins of the solar system. "We've collected a part of the solar system's history," project manager Yuichi Tsuda said at a jubilant press conference hours after the successful landing was confirmed. "We have never gathered sub-surface material from a celestial body further away than the Moon," he added. "We did it and we succeede…

https://phys.org/news/2019-07-pair-supermassive-black-holes-collision.htmlAstronomers have spotted a distant pair of titanic black holes headed for a collision.Each black hole's mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through space-time. Those cosmic ripples will join the as-yet-undetected background noise of gravitational waves from other supermassive black holes.Even before the destined collision, the gravitational waves emanating from the supermassive black hole pair will dwarf those previously detected from the mergers of much smaller black ho…

https://phys.org/news/2019-07-exoplanets-gravitational.html In a recent paper in Nature Astronomy, researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies and Atomic Energy Commission (CEA) in Saclay, Paris suggest how the planned space-based gravitational-wave observatory LISA can detect exoplanets orbiting white dwarf binaries everywhere in the Milky Way and in the nearby Magellanic Clouds. This new method will overcome certain limitations of current electromagnetic detection techniques and might allow LISA to detect planets down to 50 Earth masses. In the past two deca…

Even so, its vital science experiments keep on ticking. It is the first time that important science experiments at the Halley Research Station on the Brunt Ice Shelf have been operated remotely, thanks to a high-tech electricity generator that will run continuously for nine months in the below-freezing conditions. The generato…

With all the gloom and doom surrounding global warming, sometimes there's a sliver of good news. Planting billions of trees across the world is by far the biggest and cheapest way to tackle the climate crisis, according to scientists, who have made the first calculation of how many more trees could be planted without encroaching on crop land or urban areas. The analysis found there are 1.7bn hectares of treeless land on which 1.2tn native tree saplings would naturally grow. That area is about 11% of all land and equivalent to the size of the US and China combined. Tropical areas could have 100% tree cover, while others would be more sparsely covered, meaning …

https://phys.org/news/2019-07-x-rays-black-holes-cosmic-sea.html Like whirlpools in the ocean, spinning black holes in space create a swirling torrent around them. However, black holes do not create eddies of wind or water. Rather, they generate disks of gas and dust heated to hundreds of millions of degrees that glow in X-ray light. Using data from NASA's Chandra X-ray Observatory and chance alignments across billions of light-years, astronomers have deployed a new technique to measure the spin of five supermassive black holes. The matter in one of these cosmic vortices is swirling around its black hole at greater than about 70% of the speed of light. The …

https://phys.org/news/2019-06-comet-impacts-jump-start-life-earth.html Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly larger nitrogen-containing aromatic structures that are likely constituents of polymeric biomaterials. That is the conclusion of a new study by Lawrence Livermore National Laboratory (LLNL) researchers who explored the idea that the extremely high pressures and temperatures induced by shock impact can cause small biomolecules to condense into larger life-building compou…

https://phys.org/news/2019-07-antarctic-ice-high-lows.html The amount of ice circling Antarctica is suddenly plunging from a record high to record lows, baffling scientists. Floating ice off the southern continent steadily increased from 1979 and hit a record high in 2014. But three years later, the annual average extent of Antarctic sea ice hit its lowest mark, wiping out three-and-a-half decades of gains—and then some, a NASA study of satellite data shows. In recent years, "things have been crazy," said Mark Serreze, director of the National Snow and Ice Data Center. In an email, he called the plummeting ice levels "a white-knuckle ride." more a…

https://phys.org/news/2019-06-astronomers-history.html Cosmic waves discovery could unlock mysteries of intergalactic space: Scientists were celebrating a groundbreaking astronomical discovery Thursday that they say could pave the way for mapping the outer reaches of the universe. An Australian-led team of international astronomers have determined for the first time the precise source of a powerful, one-off burst of cosmic radio waves. They have pinpointed it to a massive galaxy billions of light years away, with properties that upend what scientists previously thought they knew about the formation of mysterious fast radio bursts (FRBs). "This re…

https://phys.org/news/2019-06-santorini-volcano-terrestrial-analogue-mars.html The Greek island of Santorini is now one of the most popular tourist destinations in the Mediterranean, but 3,600 years ago it suffered one of the largest volcanic eruptions in recorded history. Among the material that was exposed, scientists have now found rocks similar to those of Mars. "In the Balos Cove, located to the south of the island, we have discovered basalts such as those that have been identified by the rovers on Mars and with properties similar to those of certain meteorites from the red planet and those of terrestrial rocks classified as Martian analogues," says Ioannis…

https://www.aei.mpg.de/18498/03_Einstein_Telescope Einstein Telescope: The Einstein Telescope (ET) is a design concept for a third-generation gravitational-wave (GW) detector, which will be 10 times more sensitive than current instruments. Like the first two generations of GW detectors, the concept for the Einstein Telescope is based on the measurement of tiny changes (far less than the size of an atomic nucleus) in the lengths of two connected arms several kilometres long, caused by a passing gravitational wave. Laser beams passing down the arms record their periodic stretching and shrinking as interference patterns in a central photo-detector. The…

After the Roswell crash we were told it was a weather balloon. So at this time the government was accused by many of a coverup.

One of the founders of the standard model, one of the greatest particle-physicists of the 60s and 70s, has died. I remember him from a book I read when I still was at school: The scientist, from the Time-Life series. The discovery of the Omega-minus was given as an example of how scientists get to their discoveries. Gell-Mann, together with Yuval Ne'eman, predicted its existence. Gell-Mann gave his theory the name 'eightfold path'. I don't know if quarks were already implicit in his theory, or that he later got the idea that the existence of quarks would explain the symmetries he found.
