Big Bang water cracker

At www.q-mag.org/the-age-of-water-on-earth.html ... the question as to whether water is abundant in the universe has been on the mind of scientists for a long time now. Calculations using computer models have now entered the fray - and it is being suggested that it is possible there is a lot of water out there in space.

Big Bang dynamics

At http://phys.org/print342359840.html .... a German cosmologist says the theory of the quantum mode of structure in the universe has been confirmed - even proved. However, he also says that a reported signal said to confirm the existence of primordial gravitational waves can be attributed to dust in our own galaxy.

wormholes in heaven

At http://phys.org/print341045140.html ... evidence is said to exist that our galaxy could be a huge wormhole - but not everyone would agree (even physicists). The paper is in the Annals of Physics and the idea is to rethink dark matter. They can't see the stuff but apparently they can map how much dark matter is in the Milky Way. The following remark is somewhat revealing, 'obviously, we are not claiming that our galaxy is definitely a worm hole but simply that according to theoretical models this hypothesis is a possibility'.

Energy systems

At http://phys.org/print338190635.html ... is about thermoelectric power plants that seek to harvest the ocean waves by pumping cold water up through a heat exchanger

Bankrupting Physics

A book is now available, 'Bankrupting Physics: how today's top scientists are gambling away scientific credibility' and is written by Alexander Unzicker and Shiella Jones. It is said to debunk modern theoretical physics and at the same time also takes a swipe at the huge amounts of money used to fuel high energy particle accelerators. I wouldn't have the temerity to comment as I have not read the book - but anyone so inclined is welcome to write a short review and send it via the email link on the web page.

Atmospheric Gases

At http://phys.org/print333613144.html ... a paper in Nature Geoscience (Oct 2014) has suggested the origin of Earth's nitrogen rich atmosphere is due to the tectonic forces that drive mountain building, subduction, and Plate Tectonics. It also adds, presumably quoting a consensus source, the chemistry of the air we breathe has been affected by millions and millions of years of photosynthesis. The oxygen upstairs, it is thought, can be mostly explained away as due to plants and trees growing on the surface of the Earth. This sounds a bit like a chicken and egg situation.

Fluid Dynamics

Tim Cullen is turning his attention to fluid dynamics but not sure what the end result will be - go to http://malagabay.wordpress.com/2014/10/03/couette-flow-1-viscosity/ ... which may have repercussions on a lot of things we take for granted. He says there is no settled science involved because of natural complexities recognised by physicists, as such, and the use of approximations and exceptions and various controversies that have developed over the years. A good science subject then.

CERN update

At http://phys.org/print323490400.html ... we are back at CERN and the Large Hadron Collider. Not many press releases from CERN recently but they have been upgrading their baby - big time (and fast approaching a new season of experiments). The Higgs Boson particle is the focus of atttention. They have sifted through reams of experimental data  in order to understand the traits and behaviour of the particle. None of it seems capable of explaining dark matter and in addition there is no evidence of supersymmetry.

Greenhouse Venus

There is a discussion ongoing at http://tallbloke.wordpress.com/2014/06/28/venus-surface-temp-correctly-p... ... and one commenter has come on and said Venus was born from Jupiter just 6000 years ago. What is the modern view of Carl Sagan's greenhouse Venus - go to link above and join in if you like.

The cusp of cold fusion technology

At http://chiefio.wordpress.com/2014/06/04/lenr-year-of-answers/ ... 2014 is likely to be important for Cold Fusion (Low Energy Nuclear Reactors or LENR) according to www.wired.co.uk/news/archive/2014-01/15/cold-fusion-moves-into-mainstream  ... but strangely, since January it has all gone a bit quiet (so has Wired overhyped). First we have the Cyclone engine developed by Cyclone Power Technologies in the US. This can run on virtually anything - from oil, gas, biomass, powdered coal, or even by waste heat or solar collectors.
