NASA Examines Newly Formed Tropical Depression 3W in 3-D

Tropical Depression 03W formed in the Pacific Ocean west of Guam on April 24, 2017, and data from the Global Precipitation Measurement Mission or GPM core satellite was used to look at the storm in 3-D.

Tropical Depression 03W formed on April 24 at 2100 UTC (5 p.m. EDT) about 201 nautical miles north-northwest of Yap.

The GPM core observatory satellite had an excellent view of Tropical Depression 03W or TD03W when it flew over on April 14, 2017 at 1901 UTC (3:01 p.m. EDT). The GPM satellite found that the newly formed tropical depression contained some very powerful convective storms. Intense storms in the middle of the organizing convective cluster were dropping precipitation at extreme rates. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments unveiled tall convective storm towers on the eastern side of this cluster of storms that were dropping rain at a rate of over 215 mm (8.5 inches) per hour.

India's outsized coal plans would wipe out Paris climate goals

India will not be able to meet its Paris climate agreement commitments in the coming years if it carries through with plans to construct nearly 370 coal-fired power plants, according to University of California, Irvine and CoalSwarm researchers.

“India is facing a dilemma of its own making,” said UCI associate professor of Earth system science Steven Davis, co-author of a study published today in the American Geophysical Union journal Earth’s Future. “The country has vowed to curtail its use of fossil fuels in electricity generation, but it has also put itself on a path to building hundreds of coal-burning power plants to feed its growing industrial economy.”

Thought Antarctica's Biodiversity Was Doing Well? Think Again

Twenty-three experts involved in the study “Antarctica and the strategic plan for biodiversity,” recently published in PLoS Biology, debunked the popular view that Antarctica and the Southern Ocean are in a better environmental shape than the rest of the world. In fact, the difference between the status of biodiversity in the region and planet Earth as a whole is negligible.

Toronto's subways expose passengers to more air pollution than Montreal, Vancouver systems

Airborne particulates on subway platforms and trains are up to 10 times higher than outside air, around three times higher than levels in Montreal’s Metro

A new study co-authored by U of T Engineering Professor Greg Evans shows that subways increase our personal exposure to certain pollutants, even as they decrease overall emissions – and that Toronto has the highest levels in Canada.

Drug created from malaria parasite shows promise as bladder cancer treatment

A drug created from a malaria protein stopped tumour growth of chemotherapy-resistant bladder cancer, offering hope for cancer patients not responding to standard treatments.

Global Warming Making Oceans More Toxic, Research Shows

Ocean warming since the 1980s is linked to the spread of toxic algae, according to a newly published study led by Dr. Christopher Gobler, marine science professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University.

New strategy produces stronger polymers

Plastic, rubber, and many other useful materials are made of polymers — long chains arranged in a cross-linked network. At the molecular level, these polymer networks contain structural flaws that weaken them.

Several years ago, MIT researchers were the first to measure certain types of these defects, called “loops,” which are caused when a chain in the polymer network binds to itself instead of another chain. Now, the same researchers have found a simple way to reduce the number of loops in a polymer network and thus strengthen materials made from polymers.

Caterpillar found to eat shopping bags, suggesting biodegradable solution to plastic pollution

Scientists have found that a caterpillar commercially bred for fishing bait has the ability to biodegrade polyethylene: one of the toughest and most used plastics, frequently found clogging up landfill sites in the form of plastic shopping bags.

Researchers develop eco-friendly, 4-in-1 catalyst

Brown University researchers have developed a new composite catalyst that can perform four separate chemical reactions in sequential order and in one container to produce compounds useful in making a wide range of pharmaceutical products.

New Approach to Improve Detection of Landfill-Related Pollution

Numerous hazardous substances seep from landfills into soil and groundwater, threatening human health and the environment. However, current methods for monitoring these substances are cumbersome and can create additional hazardous chemicals.
