Aboriginals

Evidence of people living in western Australia 50,000 years ago has been discovered in the remote Carnavon Ranges. They lived in the region during a long part of the so called Ice Age - see https://phys.org/print456652654.html ... and a similar, but longer report can be found at https://phys.org/print456653140.html ... where it adds, '.. more than 50,000 years ago). The findings are published in PLOS One, an online journal, and the excavations are taking place in a rock shelter (with some deep diggings into the floor area).

solar constant

At https://andymaypetrophysicist.com/2018/09/19/how-constant-is-the-solar-c... ... the IPCC lowered their estimate of the impact of solar variability on the Earth's climate from the already low value of 0.12 watts per square metre given in the 4th Report to just 0.05 in the 5th Report (2013). There are long term values extended over 261 years (1750-2011) and they apply to 11 year solar cycles (sunspots). The peaks of sunspot/solar cycles vary so what is being measured is the baseline (the minimums of each cycle).

Rocket Propulsion

At https://www.eurekalert.org/pub_releases/2018-09/uop-sr091418.php ... propelling spaceships without fuel. Mike McCulloch of Plymouth University first came up with the idea of quantised inertia (QI) in 2007. This involves light being converted into thrust. QI predicts that objects can be pushed by differences in the intensity of Unruh radiation in space. The idea is similar to a ship being pushed towards its bay because there are more waves hitting it from the sea ward side of the boat.

Brown Dwarf Oddity

At https://astrobites.org/2018/09/17/over_luminous_brown_dwarf/ ... the curious case of the over luminous brown dwarf. It is theorised brown dwarfs form secondarily to main sequence stars. A gas cloud collapses, heats up, and ignites. However, brown dwarfs, the theory supposes, do not have enough mass to start forming hydrogen as in a star (and instead they form deuterium). Over time they cool off - and fade away. The brown dwarf in question is 16 times brighter than expected by the model (theory). Hence, astronomers are looking for reasons why.

Heat Wave

According to Weather Eye in The Times (of London) earlier this month the recent hot weather in Europe was caused by a huge horseshe shaped pattern of sea temperatures stretching across the North Atlantic. Throughout the summer the tropical Atlantic between the Caribbean and Africa has been coller than normal - and these cool waters arched around towards the tip of Greenland. Inside the horseshoe pattern sat a large area of unusually warm water in the Mid Atlantic.

Electron Rain

Another video - this time viewable at www.spaceweather.com (September 21st 2018). NASAs latest rocket into space has been a success, deploying the ICESat-2 which is designed to make 3D laser images of earth's surface in order to keep a tally on glaciers etc. However, a pair of tiny satellites were tucked into the rocket and also successfully deployed as well. They were built by students at UCLA's department of Planetary and Space Sciences - which are designed to monitor the ebb and flow of electrons around our planet.

Blue Sun Anomaly

At https://co2islife.wordpress.com/2018/09/17/dr-willie-soon-the-global-blu... ... is actually a link to a video by one of my favourite scientists, the much maligned (by CAGW activists) Dr Willie Soon. He is an extremely polite man even in the face of some incredible abuse by people who know as much about climate as they can write on a postage stamp. He doesn't resort to the same level of insults as his critics and always comes across as cool as a cucumber - a one time admirable human characteristic that seems to be part of history nowadays.

Fossils and Bones

Gravity - Newton and Einstein

At https://phys.org/print456129421.html ... astronomers and physicists have revived a previously debunked theory of gravity, arguing that motion within dwarf galaxies would be slower if they were close to a massive galaxy. This is the Modified Newtonian Dynamics (or MOND as it is usually referred to) - which proved to be a controversial alternative to Einstein's General Relativity model. Modern attempts to keep general relativity alive have resorted to claiming dark matter plays a role - even if it cannot be detected.
