Like many engineers, Ravi Selvaganapathy, McMaster’s Canada Research Chair in Biomicrofluidics, enjoys a challenge – the thornier, the better. His work focuses on developing small machines and tools (the “micro” in “biomicrofluidics”) and using them to improve medicine, biology and human health (the “bio”).

His latest project is about as thorny as it gets: a three-year, $1.8 million project funded by the University of Saskatchewan’s Global Water futures project to develop water sensors that can be used in resource-poor areas.

Two viruses closely related to Zika – West Nile and Powassan – can spread from an infected pregnant mouse to her fetuses, causing brain damage and fetal death, according to a new study from Washington University School of Medicine in St. Louis. The findings suggest that Zika may not be unique in its ability to cause miscarriages and birth defects.

A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a study led by the University of California, Davis. The study traces the emissions to fertilized soils in the Central Valley region.

NASA analyzed a major tropical cyclone spinning in the Southwestern Indian Ocean and measured its rainfall.

Omega-3s from fish pack a stronger punch than flaxseed and other oils when it comes to cancer prevention, according to a first-ever University of Guelph study.

Prof. David Ma has discovered that marine-based omega-3s are eight times more effective at inhibiting tumour development and growth.

The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Cyclone Fehi in the Southern Pacific Ocean season and identified heavy rainfall in the system.

When NASA's Aqua satellite passed over Tropical Cyclone Cebile it measured cloud top temperatures and saw its eye circled by an impressive ring of powerful thunderstorms just before it went through eyewall replacement.

If you install solar panels on your roof and avoid dousing your lawn with chemicals and pesticides, your online peers may consider you to be environmentally friendly. But this street cred can all be erased if you let your cat roam around outdoors.

Insects that play an essential role in moulding ecosystems may have begun their rise to prominence earlier than previously thought, shedding new light on how the world became modern. That is the finding of a new paper published by an international team of researchers led by Simon Fraser University's Bruce Archibald who is also a research associate at the Royal BC Museum.

As farmers in the American West decide what, when and where to plant, and urban water managers plan for water needs in the next year, they want to know how much water their community will get from melting snow in the mountains.

This melting snow comes from snowpack, the high elevation reservoir of snow which melts in the spring and summer. Agriculture depends on snowpack for a majority of its water. Meltwater also contributes to municipal water supply; feeds rivers and streams, boosting fisheries and tourism; and conditions the landscape, helping lessen the effects of drought and wildfires.
