Part of the sunspot group near disk center
The first pictures from the new Swedish solar telescope on La Palma, Canary Islands, are presented in an article in the prestigious science journal Nature from November 14. The images of the sun are the most detailed ever seen. One of the most sensational discoveries is a previously unknown detailed sunspot structure.
The impact of this discovery is now capturing the attention of solar researchers, and it won`t be long before new and revised theories are formulated.
The solar telescope was designed and built in Sweden and is run by the Institute for Solar Research at the Royal Academy of Science. It boasts a lens one meter in diameter and is specially constructed to cope with problems of movement in the air and atmosphere, which normally disturb in the image. All air has been pumped out of the telescope tube, and a mirror in the path of light changes shape roughly a thousand times per second to counteract disturbances from the atmosphere. This means that the pictures are the sharpest ever taken of the sun. The resolution would allow the bottom line of eye-test charts to be read from a distance of 3 km.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Research from a leading international expert on the health of the Great Lakes suggests that the growing intensity and scale of pollution from plastics poses serious risks to human health and will continue to have profound consequences on the ecosystem.
In an article published this month in the Journal of Waste Resources and Recycling, Gail Krantzberg, a professor in the Booth School of Engineering Practice...
