Climate change will drive stronger, smaller storms in U.S., new modeling approach forecasts

The effects of climate change will likely cause smaller but stronger storms in the United States, according to a new framework for modeling storm behavior. Though storm intensity is expected to increase over today’s levels, the predicted reduction in storm size may alleviate some fears of widespread severe flooding in the future.

Modifying a live virus in a vaccine to be just strong enough

By genetically tweaking the constituent live virus, scientists have created a vaccine against influenza in which the virus is capable of activating the immune system but cannot replicate in healthy cells -- an approach that may become more widely used for generating live virus vaccines adapted to other viruses.

Large-scale changes in insect species inhabiting streams and rivers

The frequencies of occurrence of hundreds of insect species inhabiting streams have been altered relative to the conditions that existed prior to wide spread pollution and habitat alteration, American scientists have discovered. Results were similar for the two study regions (the Mid-Atlantic Highlands and North Carolina), where frequencies of occurrence for more than 70 percent of species have shifted.

More frequent, more intense and longer-lasting storms cause heavier spring rain in central US

Intense storms have become more frequent and longer-lasting in the Great Plains and Midwest in the last 35 years. What has fueled these storms? The temperature difference between the Southern Great Plains and the Atlantic Ocean produces winds that carry moisture from the Gulf of Mexico to the Great Plains, according to a recent study.

A cleaner, more efficient car? New material designed to better store hydrogen fuel

New materials have been designed that could be used to store hydrogen fuel more efficiently in vehicles or other devices that use clean energy.

Increasing tornado outbreaks: Is climate change responsible?

In a new study, researchers looked at increasing trends in the severity of tornado outbreaks where they measured severity by the number of tornadoes per outbreak. They found that these trends are increasing fastest for the most extreme outbreaks. While they saw changes in meteorological quantities that are consistent with these upward trends, the meteorological trends were not the ones expected under climate change.

Gut microbes promote motor deficits in a mouse model of Parkinson’s disease

Gut microbes may play a critical role in the development of Parkinson's-like movement disorders in genetically predisposed mice, researchers report. Antibiotic treatment reduced motor deficits and molecular hallmarks of Parkinson's disease in a mouse model, whereas transplantation of gut microbes from patients with Parkinson's disease exacerbated symptoms in these mice. The findings could lead to new treatment strategies for the second most common neurodegenerative disease in the United States.

Restaurants not good at explaining risks of undercooked meat to customers

Front-line staff, such as servers in restaurants, are often trusted with providing customers with food safety information regarding their meals. A challenge to the food-service industry is that these positions have high turnover, relatively low wages and servers are focused primarily on providing patrons with a positive experience. And new research shows that this poses a problem.

Gut microbe movements regulate host circadian rhythms

Even gut microbes have a routine. Like clockwork, they start their day in one part of the intestinal lining, move a few micrometers to the left, maybe the right, and then return to their original position. New research in mice now reveals that the regular timing of these small movements can influence a host animal's circadian rhythms by exposing gut tissue to different microbes and their metabolites as the day goes by. Disruption of this dance can affect the host.
