ECAT ... update

At http://phys.org/print304868667.html ... it seems we have a post by somebody not entirely convinced of cold fusion. However, it seems that ECAT portable cold fusion plants, as developed under Andrea Rossi, are on sale - orders are being taken. The acid test is therefore coming shortly - will they work? Within three months we shall know if the first buyers are happy - or unhappy with their new toys.

Picking at Bones

Consensus theories are often kept on board long after their sell by date. People become attached to them - a sort of comfort zone. Should that apply to science - does that apply to science?

Methane, methanogens, and ice cores (again).

At http://malagabay.wordpress.com/2013/11/22/methane-myopia-7-miles-mathis/ ... we have a link to somebody also criticising mainstream's treatment of methane - go to http://milesmathis.com/meth.pdf

Tim Cullen notes that within ice cores the methanogens have a plentiful supply of water from which they could liberate hydrogen. This suggests methanogens (in ice cores) reduces co2 levels while increasing the levels of CH4 and O2 which suggests the 'settled science' of extracting climate data and atmospheric gas levels from ice cores is basically, poppycock.

The problem on the Sun

One of physics biggest unsolved problems is described at http://phys.org/print303981706.html ... where two astrophysicists claim they have 'almost' solved why the Sun's corona is much hotter than the surface of the Sun. The corona is the source of the solar wind and solar flares are a potential problem to the inhabitants of the Earth, affecting power grids and telecommunications technology (such as satellites).

Oxygen, the atmosphere, and black smokers

This is the third link that is reminiscent of Malaga Bay (remember the black smokers on the ocean bottom) - see http://phys.org/print303899664.html ... a paper in Nature Geoscience by a team from the Norwegian Geological Survey claims oxygenation of the atmosphere and oceans came about two billion years ago. This also produced phosphorous - and phosphorus was the clue to the findings. Phosphorous is an important ingredient of life and all this popped out when the team were looking at rocks in Karelia (next door to Finland but in Russia) reputed to be two billion years of age.

Methane producing microbes

Malaga Bay also came to mind when I read the headline here too - see http://phys.org/print304016779.html ... microbiologists have found that methanogen microbes can reduce carbon dioxide to methane by a mechanism in which they make 'electrical connections' with other micro organisms, something not recognised in methanogens before. Bacteria anaerobically digest biomass to produce methane gas, an important piece of bio-energy. In nature these methanogens are active in bogs, swamps, and wetland zones, and their productivity is a source of angst to climate alarmists.

the evolution of the atmosphere of the Earth

I couldn't help thinking of some of Malaga Bay's postings when coming across this at http://phys.org/print303991846.html ... a piece of research on amber deposits. A team of sicentists have analysed modern and fossil resins and the results seem to suggest there was less oxygen in the atmosphere in the geological past than previously imagined. The study therefore raises a question mark about current theories on the evolution of climate and of life itself, including the causes of gigantism in dinosaurs.

The Ring Nebula, atmospheric rivers in the sky

Tim Cullen has a post on the Ring Nebula (Messier 57) which provides an example of the fluorescence produced by gases when they are irradiated - with ultra violet light (see http://malagabay.wordpress.com/2013/11/10/fluorescing-skies/ ... complete with images

Meanwhile, at www.jpl.nasa.gov/news/news.php?release=2013-323 ... we have atmospheric river storms over the Pacific. These are short lived wind tunnels that carry water vapour from the tropical ocean to mid latitude land ares and are prolific producers of rain and snow in the Americas and East Asia

The hard and the soft of it

Cadbury's Milk Tray, brought by a hunk to a swooning lady, was depicted with a selection of hard and soft centres, chocolates to suit any taste. At www.thunderbolts.info/wp/2013/10/09/mired-in-slush-2/ ... it asks, do the centre of planets contain molten magma or a rocky slush? A gravity map of Titan made by the Cassini spacecraft in orbit around Saturn suggests its interior is a mixture of rock and ice with no layering. Variations in the gravity seem to imply a variationin density - unlike the body of Earth's Moon.

Nir Shariv at EIKE 2013

Nir Shariv of the Racah Institute of Physics in the Hebrew University of Jerusalem can be seen on video addressing the German EIKE conference on solar and cosmic ray connections with climate physics. This is not to say that what he says is embraced by the sceptic community - only that he offers an alternative view, in one respect, and one that doesn't shirk from the idea of electrical effects on the atmosphere of the Earth. His work is not the same as that of Svensmark, and colleagues, but involves cosmic rays, too.
