New record set for high-temperature superconductivity

By - August 24, 2015

With their zero electrical resistance and remarkable magnetic and thermal conductive properties, superconductors have the potential to revolutionize numerous technologies. The trouble is, they work best at cryogenic temperatures in the neighborhood of absolute zero (-273° C, -459° F). As part of the quest to come up with a room temperature superconductor, researchers from the Max Planck Institute for Chemistry and the Johannes Gutenberg University Mainz have developed a new record-high-temperature superconductor – and it smells like rotten eggs.

Chilly European winters linked to solar activity

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.

Gastric bacterium protects against asthma and proves hygiene hypothesis

By - July 5, 2011
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. Read More
