University of Minnesota professor is part of international team that predicts the volatile region’s water may once again vanish
MINNEAPOLIS / ST. PAUL — An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period similar to predicted scenarios for climate change in coming decades. Emi Ito, professor of earth sciences in the University of Minnesota’s College of Science and Engineering, is a research team member. (more…)
Scientists have observed a strategy for females to avoid unwanted male attention: choosing more attractive friends.
Published in the journal Proceedings of the Royal Society B, the study is the first to show females spending time with those more sexually attractive than themselves to reduce harassment from males.
Carried out by the Universities of Exeter and Copenhagen, the study focuses on the Trinidadian guppy, a species of small freshwater fish. It shows that the females choose companions that are relatively more attractive than themselves and in this way reduce harassment from males. The research shows that the tactic is successful and by ensuring they are less attractive than other group members, the fish experience less harassment and fewer mating attempts from males. (more…)

While the worst drought since the Dust Bowl of the 1930s grips Oklahoma and Texas, scientists are warning that what we consider severe drought conditions in North America today may be normal for the continent by the mid-21st century, due to a warming planet. (more…)
With news this week of additional radioactive leaks from Fukushima nuclear power plants, the impact on the ocean of releases of radioactivity from the plants remains unclear. But a new study by U.S. and Japanese researchers analyzes the levels of radioactivity discharged from the facility in the first four months after the accident and draws some basic conclusions about the history of contaminant releases to the ocean.
