Credit: PNAS Thousands of bones from boys and men likely killed in a ferocious battle 2,000 years ago have been unearthed from a bog in Denmark, researchers said Monday. Without local written records to explain, or a battlefield to scour for evidence, experts are nevertheless piecing together a story of the Germanic people, often described by the Romans as "barbarians" for their violent nature. Four pelvic bones strung on a stick were among…

This is still highly controversial in the science world, so if the mods and/or admins see it as more appropriate for "speculation" then I welcome it removal to that section. My thoughts on this have always been that no known laws of physics were ever broken, rather that some apparent as yet unknown aspect could be at work. The following article and hypothetical seems to support those thoughts........ https://www.sciencealert.com/physicists-have-a-weird-new-idea-about-how-the-impossible-em-drive-could-produce-thrust This Overlooked Theory Could Be The Missing Piece That Explains How The EM Drive Works What if it doesn't break the laws of physics?…

They report having recorded gamma ray flashes with up to 20 MeV, which could have only been Matter-Antimatter annihilations. Since Positrons and Electron annihilate with 511 keV each, this is entirely possible. They're still unsure how exactly the positrons were created in the storm. My best guess would be that a few virtual electron-positron pairs were separated and the positrons were accelerated too fast toward the earth to interact with electrons in their vicinity. Well, just because it's my best guess doesn't mean it's a …

https://phys.org/news/2018-05-alma-most-distant-oxygen-universe.html Astronomers find evidence for stars forming just 250 million years after Big Bang May 16, 2018, National Radio Astronomy Observatory Not long after the Big Bang, the first generations of stars began altering the chemical make-up of primitive galaxies, slowly enriching the interstellar medium with basic elements such as oxygen, carbon, and nitrogen. Finding the earliest traces of these common elements would shed important light on the chemical evolution of galaxies, including our own. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) reveal the faint, te…

https://phys.org/news/2018-05-astronomers-fastest-growing-black-hole-space.html Astronomers find fastest-growing black hole known in space May 15, 2018, Australian National University Astronomers at ANU have found the fastest-growing black hole known in the Universe, describing it as a monster that devours a mass equivalent to our sun every two days. The astronomers have looked back more than 12 billion years to the early dark ages of the Universe, when this supermassive black hole was estimated to be the size of about 20 billion suns with a one per cent growth rate every one million years. "This black hole is growing so rapidly that it's shini…

What can be done with this Hawaii volcano to prevent future loss of property? Got to be some Geo Physicists or Engineers on a site like this. Seems like an investment in a horizontal drilling rig to reach the nearest lava tube and give it every reason flow out into the sea (and admittedly the million dollar drilling rig). Hence the description "investment." Assume economics is no major issue. Surely something can be done to mitigate future problems. Pump a benign gas down there to force a controlled eruption? Pump Water down? Open artificial fissures in unpopulated areas to release pressure? Giant Slurpee Machine and pump the flavorful ice slurry into a ma…

This is another case where we discovered the asteroid, then lost it for several years, only to find it again just a week ago. Which would seem to indicate that just because NASA may have discovered 98% of the NEOs larger than 1 km, it does not mean that they know where those NEOs are now. Of the 17,785 NEOs (as of March 1, 2018) that NASA has discovered, I would be very interested in knowing the percentage of NEOs that NASA has lost since their discovery.

This BBC report is interesting as it is about a working test installation to inject atmospheric CO2 into volcanic basalt rock, permanently removing it from the atmosphere. http://www.bbc.co.uk/news/world-43789527

I’d quite like to open a thread discussing the possible pros and cons of using this technique in humans. Where would I post it please? Summary: Glanzman and his team gave the snails a series of electric shocks to their tails. "The result is, their reflexes were greatly enhanced. If we touched their skin, they'll contract very strongly." When the snails were good and jumpy, the team extracted RNA from their nervous systems and injected it into untrained snails. "Twenty-four hours later, we tested the reflexes of those snails, and they showed the same reflexes of those that had been given electrical shocks," Glanzman said. …

https://phys.org/news/2018-05-evidence-plumes-jupiter-moon-europa.html Old NASA spacecraft points to new evidence of watery plumes over Europa May 14, 2018: A fresh look at data from a 1997 flyby of Jupiter's moon, Europa, suggests that NASA's Galileo spacecraft flew directly through a watery plume, raising hopes of probing the jets for signs of life around the second planet from Earth. The revelations Monday came after scientists revisited a puzzling reading from an instrument aboard Galileo, which in 1995 became the first spacecraft to enter the orbit of a gas giant planet. What they found was the most direct evidence yet of plumes emerging from…

http://www.sci-news.com/astronomy/westerhout-43-star-formation-05962.html New Study Casts Doubt on Currently Accepted Theories of Star Formation: An international team of astronomers has found that long-held assumptions about the relationship between the mass of star-forming clouds of dust and gas and the eventual mass of the star itself may not be as straightforward as scientists think. Their work is published in the journal Nature Astronomy. The underlying reasons as to why a star eventually grows to a specific mass has puzzled astronomers for years. It has been assumed that a star’s mass mostly depends on the original structure — known as a …

Earth's magnetic field is not about to reverse, study finds April 30, 2018, University of Liverpool A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers, including the University of Liverpool, has found it is unlikely that such an event will take place anytime soon. There has been speculation that the Earth's geomagnetic fields may be about to reverse , with substantial implications, due to a weakening of the magnetic field over at least the last two hundred years, combined with the expansion of an identified weak area in the Earth's magnetic field called the South Atlantic Anomaly, which stretches from…

https://phys.org/news/2018-05-sagittarius-swarm-black-hole-bounty.html Sagittarius A* swarm: Black hole bounty captured in the Milky Way center: Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA's Chandra X-ray Observatory. This black hole bounty consists of stellar-mass black holes, which typically weigh between five to 30 times the mass of the Sun. These newly identified black holes were found within three light years—a relatively short distance on cosmic scales—of the supermassive black hole at our Galaxy's center known as Sagittarius A* (Sgr A*).

Would aliens who evolved on a Super Earth be trapped due to the difficulty of leaving the planet? A Super Earth 16,000 miles in diameter with a similar density would have a volume 8 times Earth's, 4 times the surface area, and twice the gravity. Escape Velocity would be twice Earth normal?

https://phys.org/news/2018-05-ancient-scientists-climate-deep.html Earth's orbital changes have influenced climate, life forms for at least 215 million years May 7, 2018, Columbia University Scientists drilling deep into ancient rocks in the Arizona desert say they have documented a gradual shift in Earth's orbit that repeats regularly every 405,000 years, playing a role in natural climate swings. Astrophysicists have long hypothesized that the cycle exists based on calculations of celestial mechanics, but the authors of the new research have found the first verifiable physical evidence. They showed that the cycle has been stable for hundreds of millions…

https://phys.org/news/2018-04-team-aims-nasa-telescope-capture.html Team aims to use new NASA telescope to capture light from the first stars to be born in the universe About 200 to 400 million years after the Big Bang created the universe, the first stars began to appear. Ordinarily stars lying at such a great distance in space and time would be out of reach even for NASA's new James Webb Space Telescope, due for launch in 2020. However, astronomers at Arizona State University are leading a team of scientists who propose that with good timing and some luck, the Webb Space Telescope will be able to capture light from the first stars to be born in the u…
