measuring the decay at earth's core

This one is interesting - if only that it begins with an assumption, nuclear activity is at the heart of the sun and affects all the planets in various ways. At http://phys.org/print392615199.html ... we learn that scientists are keen to find out how much fuel is left inside the earth - on the assumption it is the decay rate that provides the warmth to keep Plate Tectonics in motion (as well as several other earth phenomena). In other words, nuclear energy produced during natural radioactive decay.

Particles

Jovan Kesic forwarded the link www.skyandtelescope.com/astronomy-news/fifth-force-permeate-universe0818... ... it seems theoretical physicists are saying they have found a fifth force. The comments are not exactly confident about this but the relevant paper is currently at the arXiv preprint server for anyone to look at. The study author thinks it may help solve the dark matter issue.

Neutrinos

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.

Fractals

Excellent post at http://phys.org/print386924983.html ... and the maths behind fractals, the phenomenon of fractals in nature, and we might add, fractals in art. If you want to learn something more about the subject of fractals this might whet your appetite and encourage you to learn more. For example, the architect of the new Barcelona cathedral used fractals to achieve maximum light inside the building. Antoni Gaudi studied how plants grew, the patterns and fractals, and produced a masterpiece of architecture.

Neoproterozoic

At http://phys.org/print385967844.html ... supercomputers on the trail of dark matter is the headline.

Michio Kaku

The God Scam might be one way to phrase it but Michio Kaku, a theoretical physicist, is said by some to have found evidence of God's existence, via particle physics. Dr Wile is sceptical. He doesn't think so - see http://blog.drwile.com/?p=14864 ... which probably means some people have been duped. The particles appear to be a figment of the imagination.

bigger than Higgs, bigger than GWs ... and it's ...

At www.newscientist.com/article/2078975-bigger-than-higgs-bigger-even-than-... ... yes, the Large Hadron Collider might have found something - gigger than the Higgs Bosun, bigger even than gravitational waves - but what. A particle that may help to explain the workings of three of the fundamental forces of nature - electromagnetism, and nuclear.

getting round a problem

At http://phys.org/print375467925.html ... getting round the problem of a gamma ray burst being detected at the same time as the hypothetical merger of two black hole has not vexed mainstream for too long - just a couple of days it would seem. We now have a black hole swalling a massive star - and spitting out a gamma ray burst.

At http://phys.org/print375441286.html .... we have a little history of 'globular clusters' - don't know what they are then read the link. The role of Charles Messier is interesting.

How to respond ...

How to respond to the discovery of gravitational waves that are thought to originate in the merger of two black holes has been difficult. One could pass it over - out of my depth so to speak, or quote www.thunderbolts.info as they appear to have a view (if only on the forum). Its a big learning curve to go back and have another look at the black hole theory and General Relativity etc. Do black holes  exist - in reality rather than in the mind of cosmologists. Don't know. Simple as that.

oxygen

At http://phys.org/print373313880.html ... scientists have discovered two new iron oxides in experiments. These seem to point to a huge, hitherto unknown oxygen source in the lower mantle of the earth. Published in Nature Communications (Feb 2016) Elena Bykova estimated an amount of oxygen equivalent to 8 or 10 times the mass of oxygen in the atmosphere. That is a surprise, she said, and we don't know what happens or what is going on with the oxygen in the lower mantle.
