Weekly Roundup 75

Occasionally I struggle when it comes to finding papers to write about over the course of a week. Sometimes there is a shortage of papers published, sometimes the papers are there but I can’t understand them well enough to be confident in writing about them. Luckily most of the time it’s the opposite problem and I end the week with at least a few papers that I didn’t have room include because there were just six others papers slightly more interesting. Today I’ll be writing a quick blurb on each of these papers over the last week and perhaps I’ll continue this into the future.

There was a paper that described the recent evolution in the longwave radiation output of the Earth. The Earth’s main method of radiating the heat it absorbs is through longwave radiation which can then affect global precipitation. A Hadley cell is a specific air circulation where warm air rises at the equator, moves poleward and then descends in the subtropics. This paper examined the results of the shrinking accession current of this cell and the reduced numbers of high clouds (cirrus and its brethren) on outgoing radiation.

Another paper described the application and adaptation of neuroimaging techniques, that have hereto only been used on rodents, onto non human primates such as marmosets. Using a double excitation technique on calcium ions (Ca2+) which work to form dendric (tree like) formations for neurones in the brain. It may be possible to study the entire primates brain under both sick and healthy conditions using this technique.

The final paper that didn’t quite make the cut was describing the development of new magnetic nanostructures. Traditionally such structures, which have applications in memory storage, imaging methods, magnetic fluids, magneto-optics and so on, are flat and two dimensional. New synthesis techniques presented aim to grow these structures into three dimensions which is a completely unexplored area of science. Paper links: Three-dimensional nanomagnetism

There you go, three papers (technically the last one is a review article but its still very interesting) which could easily have been made into posts and there are three more beyond these that I could also try writing a paragraph on. But sometimes you need to smile and be happy with the work you’ve done and move on to something else. Until tomorrow, goodnight.
