It is widely recognized that rainfall over the Yangtze River valley (YRV) strengthens considerably during the decaying summer of El Niño, as demonstrated by the catastrophic flooding suffered in the summer of 1998. Nevertheless, the rainfall over the YRV in the summer of 2016 was much weaker than that in 1998, despite the intensity of the 2016 El Niño having been as strong as that in 1998. A group of scientists from the Institute of Atmospheric Physics, Chinese Academy of Sciences, have now revealed the remarkable role played by the mid-latitude circulation in this surprising feature.

As 3-D printing has become a mainstream technology, industry and academic researchers have been investigating printable structures that will fold themselves into useful three-dimensional shapes when heated or immersed in water.

In a paper appearing in the American Chemical Society’s journal Applied Materials and Interfaces, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and colleagues report something new: a printable structure that begins to fold itself up as soon as it’s peeled off the printing platform.

Researchers at the University of Alaska Fairbanks’ Geophysical Institute are exploring the changing chemistry of the Arctic’s atmosphere to help answer the question of what happens as snow and ice begin to melt.

Former Hurricane Otis was not showing any thunderstorm development or precipitation on satellite imagery on Sept. 19. As a result, the National Hurricane Center declared Otis a remnant low pressure area.

People who handle paper receipts regularly may be at increased risk for exposure to a chemical linked to breast and prostate cancers, according to new UAlberta research.

“We found that people who handled receipts printed on thermal paper containing the chemical had it lingering in their body for a week or more,” said Jiaying Liu, a PhD candidate in UAlberta’s Department of Laboratory Medicine and Pathology.
