The presence of artificial sweeteners in rural groundwater shows evidence for contamination by local septic system wastewater, researchers from the University of Waterloo have found.

Off Track: How Storms Will Veer in a Warmer World
November 15, 2017 11:29 AM - Weizmann Institute of Science

Under global climate change, the Earth’s climatic zones will shift toward the poles. This is not just a future prediction; it is a trend that has already been observed in the past decades. The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating poleward. In a paper that that was recently published in Nature Geoscience, Weizmann Institute of Science researchers provide new insight into this phenomenon by discovering that mid-latitude storms are steered further toward the poles in a warmer climate. Their analysis, which also revealed the physical mechanisms controlling this phenomenon, involved a unique approach that traced the progression of low-pressure weather systems both from the outside – in their movement around the globe – and from the inside – analyzing the storms’ dynamics.  

CRISPR-carrying nanoparticles edit the genome
November 15, 2017 11:11 AM - Massachusetts Institute of Technology (MIT)

In a new study, MIT researchers have developed nanoparticles that can deliver the CRISPR genome-editing system and specifically modify genes in mice. The team used nanoparticles to carry the CRISPR components, eliminating the need to use viruses for delivery.

Mutated frog gene repels predators
November 15, 2017 08:17 AM - University of Saskatchewan

Post-doctoral researcher Andrés Posso-Terranova and his former supervisor José Andrés have found evidence that a single gene called MC1R controls the deep black color on the skin of these poisonous frogs. The researchers have found that the disruption of the gene is responsible for the black blobs and stripes. Their results have been published this week in the international journal Evolution.

With Launch of New Night Sky Survey, UW Researchers Ready for Era of 'Big Data' Astronomy
November 14, 2017 02:51 PM - University of Washington

The first astronomers had a limited toolkit: their eyes. They could only observe those stars, planets and celestial events bright enough to pick up unassisted. But today’s astronomers use increasingly sensitive and sophisticated instruments to view and track a bevy of cosmic wonders, including objects and events that were too dim or distant for their sky-gazing forebears.
