Severe weather model predicted tornado's path hours before it formed

As severe weather brewed in the Texas panhandle late in the afternoon of May 16,  NOAA’s National Weather Service forecasters alerted residents in parts of western Oklahoma about the potential for large hail and damaging tornadoes that evening, particularly in the area around Elk City.

Ninety minutes later, a dangerous, rain-wrapped EF2 tornado struck the small town. It killed one, injured eight and destroyed about 200 homes and more than 30 businesses.  

CEO Says Mexico Oil Find Is 'Multiples Of What We Thought'

It’s been a few years of soul-searching for Tim Duncan, the CEO of Talos Energy. The Houston-based oil company has long specialized in the shallow waters of the Gulf of Mexico off Louisiana and Texas. Yet the oil bust that began in 2014 has made the region deeply unpopular. Facing dwindling prospects for big new finds offshore, companies have instead flocked to the Permian basin of west Texas, where layer upon layer of oil-saturated rock promises decent returns even at stubbornly low oil prices.

“We resisted the temptation to join the land race onshore,” says Duncan. But Talos did go somewhere new: Mexico. 

Scientists Design Solar Cell That Captures Nearly All Solar Spectrum Energy

A SEAS researcher helped develop technology that could become the most efficient solar cell in the world.

Study: Calcium Levels Could Be Key to Contracting — and Stopping — C. Diff

It lurks in hospitals and nursing homes, surviving cleaning crews’ attempts to kill it by holing up in a tiny, hard shell. It preys upon patients already weak from disease or advanced age.

Global warming could result in losses for the European wine industry

Slight increases in temperature in Mediterranean regions from global warming could potentially result in labour, productivity and economic losses for the European wine industry, an article in the journal Temperature suggests.

Getting to the roots of Sahara mustard invasion in the American Southwest

In 2015, a rural community in southeastern California approached Daniel Winkler and his doctoral advisor, Travis Huxman, for help with an invader that was hurting their local economy. An Old World annual plant called Sahara mustard (Brassica tournefortii) was spreading rapidly through the deserts of the southwestern U.S., carpeting the local Anza-Borrego Desert in spring, and smothering the native wildflowers that draw tourists to the region. Loss of native plants put the animals that depend on them for food and shelter at risk. The mustard was disrupting the entire desert ecosystem.

Climate change could mean more weight restrictions and higher costs for airlines

As air temperatures rise at constant pressure, the density of air declines and this makes it harder for an airplane to take off. Increased air temperatures due to climate change could therefore present a new challenge for the aviation industry. This is according to Ethan Coffel of Columbia University in the US, lead author of a study in Climatic Change Letters which is a section in Springer’s journal Climatic Change. 

Study suggests route to improving rechargeable lithium batteries

Most of today’s lithium-ion batteries, which power everything from cars to phones, use a liquid as the electrolyte between two electrodes. Using a solid electrolyte instead could offer major advantages for both safety and energy storage capacity, but attempts to do this have faced unexpected challenges.

Study Finds Toxic Mercury is Accumulating in the Arctic Tundra

Vast amounts of toxic mercury are accumulating in the Arctic tundra, threatening the health and well-being of people, wildlife and waterways, according to a UMass Lowell scientist investigating the source of the pollution. 

A research team led by Prof. Daniel Obrist, chairman of UMass Lowell’s Department of Environmental, Earth and Atmospheric Sciences, found that airborne mercury is gathering in the Arctic tundra, where it gets deposited in the soil and ultimately runs off into waters. Scientists have long reported high levels of mercury pollution in the Arctic. The new research identifies gaseous mercury as its major source and sheds light on how the element gets there. 

New biofuel technology cuts production time significantly

New research from a professor of engineering at UBC’s Okanagan Campus might hold the key to biofuels that are cheaper, safer and much faster to produce.

“Methane is a biofuel commonly used in electricity generation and is produced by fermenting organic material,” says Cigdem Eskicioglu, an associate professor with UBC Okanagan’s School of Engineering. “The process can traditionally take anywhere from weeks to months to complete, but with my collaborators from Europe and Australia we’ve discovered a new biomass pretreatment technique that can cut production time nearly in half.”
