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'.
At http://phys.org/print341136762.html ... cosmic magnetic fields is the subject here and something called 'Weibel filamentation instabilities' - a plasma instability present in homogenous, or nearly homogenous. electromagnetic plasmas. It has attracted a fair amount of theoretical interest from plasma physicists and this news release follows the publication of a paper in Nature Physics published in January (2015). Laboratory produced weibels appear to conform to the hypothesis of magnetic field origins and growth.
At http://phys.org/print341155255.html ... the journal Science, January 23rd, has published four articles on the Rosetta Mission - so get down to WH Smith's. Mind you, they are still saying the comet is composed of ice, dust, and space debris, a left over of the early days of the solar system. The lens they are looking through may not have changed too much but they are dealing with lots of new information. Describing the visual outline of the comet they say it is roughly the shape of a rubber duck, two lobes connected by a thin neck.

This is an interesting one as uranium isotopes are used to date rocks and float the geochronological time span. The story is at http://phys.org/print340960522.html ... and no doubt some people are inclined to doubt the whole exercise. Never the less it is all part of the Uniformitarian construct and requires understanding by critics and those with just a thirst for general knowledge. Basically, uranium isotopes are used to date the different rocks assigned to the different periods in the geochronology that has been developed over the last couple of hundred years.
Comet Lovejoy is currently visible in binoculars as a greenish blob approaching the Pleiades, east of Orion. We now have a second comet that has sparked into brightness - Comet Finlay. The TV doctor's namesake can be seen with binoculars in Aquarius, very close to its brightest star. This is located in the SW area of the night sky - for more information go to Http://phys.org/print340879696.html ...

This is no surprise, as it stands, as that is the date early farmers arrived in Ireland, and in Britain. However, it shows they managed to ship their animals in at a fairly rapid pace, presumably by sea - but from where?
At http://chauvetdreams.co.uk/2014/07/70000-year-old-african-settlement-une... .... it seems, not just Neanderthals were being underestimated but Middle Palaeolithic people in Africa as well. People were living in a village of wooden huts with a separate flint workshop and an animal butchering site located at a distance, 70,000 years ago.
At http://phys.org/print340618543.html ... the accepted theory on what causes plankton blooms is under attack by a marine botanist. Currently, a phyto plankton hot spot in the mid Atlantic has been chosen as the point of study - funded by NASA. Presumably this is an effort to understand the carbon cycle in the oceans.
