Again, another strange article from Scientific American - an attempt to bamboozle the conspiracy theorists and end of world doom mongers (that is sure to be ignored by people using social media). Go to www.scientificamerican.com/article/is-earth-safe-from-asteroid-bennu/ ... where all we can say is that it has an interesting name. Bennu was cosmic body that periodically threated ancient Egypt (or in mainstream speak, the phoenix rising from the ashes).
Reference the post a couple of days ago on modelling that came up with a habitable Venus some 715 million years ago. Well, the full article was in Scientific American - go wo www.scientificamerican.com/article/hellish-venus-might-have-been-habitab... .... and make of it what you will. The point of the piece is puzzling as we don't know if Venus was ever habitable. It's simply a trick of computer simulation.
This is a good one. It now seems you can so anything with computer simulation. At http://phys.org/print389947158.html ... modelling has shown Venus could have been habitable, 715 million years ago.
A nice piece of observation by a marine ecologist doing work for NOAA - evidence that humpback whales drive off orca pods attacking other marine species. Orcas will attack the young of humpback whales so there is no love lost. However, they appear to thwart killer whale attacks on sea lions, harbour seals, sunfish and gray whales, if they get the chance. The article was published in the August issue of Marine Mammal Science (2016). See http://phys.org/print390029961.html
At http://phys.org/print390034843.html ... has a star cluster ruled out MACHOs - and put to bed the idea that black holes lurk in galactic halos? We are told, 'we can't detect light in these objects - but this now adds to the gravitational pull of galaxies' ... which is part and parcel of the search for dark matter.
At http://phys.org/print390032709.html .... work on the M4/M5 junction just outside Bristol (south Gloucestershire) has revealed a couple of bone beds going back 200 million years ago. A Kentucky undergraduate at the University of Worcester analysed samples taken 25 years ago (when the motorway junction was built or upgraded) and she has discovered they were not caused by a single flooding event, as previously deduced, but by more than one transgression event.
At http://phys.org/print390048755.html ... amongst the ash of numerous animal sacrifices on a mountain dedicated to Zeus in Greece has been found the skeleton of a human sacrifice, a teenager, and dates back to the end of the Late Bronze Age. This was a time when the Mycenaean Greek kingdoms were overwhelmed in a catastrophe of some kind, most of their towns and villages were completely destroyed (and abandoned). A human sacrifice on a mountain top, directly facing the sky, and as near to the sky one can get, is a clue that something was going on upstairs.
I don't suppose water fowl are too common in the Great Basin, although there are some lakes, relics of much larger bodies of water. The environment is generally dry but in the past it has been quite wet - enough rain to form lakes. Even at 12,000 years ago water fowl (ducks and geese etc) were definitely on the menu of hunter gatherers - see http://westerndigs.org/12000-year-old-camp-found-in-utah-may-have-expert... ...
At http://phys.org/print389866610.html ... evidence is mounting that neutrinos are the key to the universe's existence, according to a news release from Imperial College in London. It includes Japanese research as well as the team from Imperial and revolves around differences in the make up of neutrinos and anti-neutrinos. Basically, they have divided the particles into tau, muons and electrons, but what differs between neutrinos and anti-neutrinos is the rate of change, from muon to electron.
Two takes on the same discovery. The newspaper likes the Arthurian angle and dallies a bit - www.independent.co.uk/news/science/archaeology/king-arthur-castle-cornwa... ... and www.medievalhistories.com/luxury-tintagel-early-medieval-period/ ... the excavations in July came across buildings, it is thought, dating to the 5th century AD (or roughly contemporary when Gildas when writing his missive, The Ruin of Britain).
