Damaging thunderstorm winds increasing in central U.S.      (via sciencedaily.com)     Original source 

Destructive winds that flow out of thunderstorms in the central United States are becoming far more widespread with warming temperatures, according to new research. A new study shows that the central U.S. experienced a fivefold increase in the geographic area affected by damaging thunderstorm straight line winds in the past 40 years.

Dam removals, restoration project on Klamath River expected to help salmon, researchers conclude      (via sciencedaily.com)     Original source 

The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.

Amphibians have one more thing to worry about--mercury      (via sciencedaily.com)     Original source 

The first widescale assessment of methylmercury in adult amphibians in the U.S. to date shows that, in amphibians, this toxic compound is common, widespread and, at least for some, can reach very high levels.

The importance of the Earth's atmosphere in creating the large storms that affect satellite communications      (via sciencedaily.com)     Original source 

Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.

Evolutionary chance made this bat a specialist hunter      (via sciencedaily.com)     Original source 

It is generally believed that, for millions of years, bats and the insects they hunt at night have adapted to each other in an evolutionary arms race to become better at finding or avoiding each other. Now, a new study shows that this may not be the case at all.

Scientists find two ways that hurricanes rapidly intensify      (via sciencedaily.com)     Original source 

Scientists at NCAR have identified two entirely different modes of hurricane rapid intensification. The findings may lead to better understanding and prediction of these dangerous events.

Fruit, nectar, bugs and blood: How bat teeth and jaws evolved for a diverse dinnertime      (via sciencedaily.com)     Original source 

Noctilionoid bat species evolved wildly different faces as they adapted to exploit diverse food sources -- including insects, fruit, nectar, blood and fish. New research shows that those adaptations include dramatic, but also consistent, modifications to tooth number, size, shape and position.

Roosters might recognize themselves in the mirror      (via sciencedaily.com)     Original source 

Scrape, cluck, lay eggs -- that's it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental conditions -- a finding that points beyond the experiment with roosters and could also be of importance for other animal species.

To navigate the world, we all shimmy like these electric fish      (via sciencedaily.com)     Original source 

An electric knifefish shimmies in the water for the same reason a dog sniffs or a human glances around a new place -- to make sense of their surroundings. For the first time, scientists demonstrate that a wide range of organisms, even microbes, perform the same pattern of movements in order to sense the world.
