Chances are that if you were heading into battle, you wouldn’t wish that you were covered in sponges. It turns out that the sea sponge, however, has a unique structure that allows it to be flexible while remaining relatively impervious to predators. Scientists have now simulated this structure, in a lab-created material that may someday find use in body armor.
Some clever cross-referencing has helped an international team of researchers establish a link between low periods of solar activity and frosty European winters. The Sun's level of magnetic activity follows an 11-year cycle. Peaks in this cycle pose a threat to telecommunications and electricity networks
and it's long been suspected that there's a correlation between the opposite end of the cycle and extreme winters in Europe. A lack of historical average temperature data makes it difficult to confirm this link, but scientists have filled the gap by studying the comings and goings of 19th Century riverboats on the Rhine.
It’s widely recognized that asthma rates have increased significantly since the 1960’s and continue to rise. With increases in asthma and other allergic diseases centered on industrialized nations, a recent hypothesis suggested that the disappearance of specific microorganisms that populate the human body due to modern hygiene practices might be to blame. Now researchers claim they have confirmed this hypothesis by proving that a certain gastric bacterium provides reliable protection against allergy-induced asthma.
