Ignoring the fact the weather is far from hot, global warming is still the chosen field for throwing money at - and one of the latest offerings is a study published in the International Journal of Modern Physics B (at the end of May, 2013) see http://phys.org/print289149026.html. It claims that Chloroflourocarbons are to blame for global warming in the 1970s to 1990s, an apparent about face. However, the intriguing point they claim as evidence is that a worldwide UN ban on the use of these CFCs has resulted in the cooling witnessed in the 2000s.
An interesting post at http://malagabay.wordpress.com/2013/04/15/why-the-sky-is-blue/ ... which according to Wikipedia, and various others, the sky is blue because air scatters short wavelength light more than longer wavelenths. The human eye perceives the colour blue when looking at the sky rather than at the Sun (http://en.wikipedia.org/wiki/Diffuse_sky_radiation ... which implies the Wikipedia editor has forgotten that Indigo and Violet have shorter wavelengths than blue light.
A paper in Nature by Tobias and Cettaneo is discussed at http://tallbloke.wordpress.com/2013/05/steve-tobias-rediscovering-the-so... ... which claims researchers at Leeds and Chicago universities have discovered a mechanism behind the generation of magnetic fields such as that of the Sun. The solution is a solar dynamo. It also takes into account plasma - which is ionised gas. Steve Tobias is from the University of Leeds School of Mathematics.
The first one is recommended by a recent Thunderbolts newsflash, The Fourth Phase of Water: beyond solid, liquid and vapor, by Gerald Pollack (2013). It can be purchased through Thunderbolts or from Amazon, via the seller, Ebner and Sons Publishing. The subject has implications in space, the universe, and the production of energy - see a preview of his ideas at www.youtube.com/watch?v=3nGCMQ8T3_g and see also www.ebnerandsons.com for further information on the book.
At http://phys.org/print287652251.html ... new research from the Australian National University has revealed the centre of Earth is out of sync with the rest of the planet, frequently speeding up and slowing down. The inner core also rotates at a different rate from the mantle - but the speed varied. Consensus theory is that the rotation rate of the inner core is constant. Consensus likes constants and dislikes uncertainty.
At www.dailygalaxy.com/my_weblog/2013/04/dark-matter-is-the-tip-of-an-icebe... ... ten years ago many astronomers or particle physicists disagreed that dark matter was important but now, that has changed. The post is about comments made by R Kolb and M Turner, authors of The Early Universe, a book that has become a standard textbook for students of cosmology and physicists alike. In the Galaxy piece they outline the way they think of dark matter and dark energy.
Prof. Trevor Palmer sent in the following piece, gleaned from the New Scientist 'special issue' of 2nd March. The headline on the cover asks, 'We've run out of explanations for the Universe. What's next?'. In the first article, 'Roots of Reality' Brain Greene, a theoretical physicist at Columbia University, New York, asks, 'what makes us so sure that mathematics can reveal nature's deepest workings?' He adds, 'deciding which mathematics to take serious is as much art as it is science'.
The size of clouds can vary under the influence of a global 'electrical heartbeat' in the atmosphere, University of Reading researchers have claimed. They looked at ten years of data fron the north and south poles, after becoming aware of the daily global ebb and flow of an electrical current in the atmosphere, the so called Carnegie Curve. The electricity came from electrified storms across the world and appears to affect the formation of clouds, or their thickness.

Lots of science history. See also HH Ricker at http://tallbloke.files.wordpress.com/2013/03/ricker7.pdf ... did Kepler think in terms of a magnetic force which drove planets in their own orbits, towards the Sun and around the Sun? Hans Jelbring replied, the gravitational force proportional to the inverse distance squared is only working at two moments in one orbital circuit.
