When it comes to the mating game, it’s true that size does matter for North American male dance flies, who are most attracted to mates who display the largest inflatable abdominal sacs, says Rosalind Murray, a post-doctoral researcher in biology at the University of Toronto.

It’s no longer a question of whether Alberta is getting hotter — and a half-century of detailed satellite climate data has led University of Calgary researchers to determine exactly how much hotter, down to the scale of an average parking stall.

New NOAA research looking at the devastating 2017 Atlantic hurricane season projects that should similar weather conditions occur in the future, it’s likely the number of major hurricanes (category 3 and higher) would increase by two in a similar active year at the end of century.

Where do pesticides and their degradation products go once they enter the soil? And how long does it take them to get to groundwater or drainage systems? That depends on a number of factors, but researchers at Aarhus University have come a step closer to finding quick answers. For the first time ever, they have used visible/near-infrared spectroscopy to predict the transport of dissolved chemicals through intact soil. 

Even after being severely damaged by blast fishing and coral mining, coral reefs can be rehabilitated over large scales using a relatively inexpensive technique, according to a study led by the University of California, Davis, in partnership with Mars Symbioscience.

A new double-decker bus in the English city of Southampton will filter pollutants from the air as it drives, several news outlets reported. The diesel bus’s filtration system, which is attached to its roof, traps 99.5 percent of ultra-fine particles and releases clean air in its wake.

NASA’s Terra satellite passed over the Eastern Pacific Ocean and provided forecasters with a visible image of Hurricane Rosa that gave an indication an eye has formed. Rosa is expected to become a major hurricane by Thursday, Sept. 27.

As Tropical Storm Kirk came back to life, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall. Kirk is headed toward the Lesser Antilles and Warnings are in effect.

Arctic sea ice likely reached its 2018 lowest extent on Sept. 19 and again on Sept. 23, according to NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. Analysis of satellite data by NSIDC and NASA showed that, at 1.77 million square miles (4.59 million square kilometers), 2018 effectively tied with 2008 and 2010 for the sixth lowest summertime minimum extent in the satellite record.

An oasis in the hostile Arctic Ocean sustained marine life and ocean circulation during the last Ice Age, according to a new study.
