Ship engine emissions adversely affect macrophages
In cooperation with colleagues of the University of Rostock, the University of Luxembourg, the Max Delbrueck Center for Molecular Medicine, the Karlsruhe Institute of Technology and the University of Eastern Finland, the Munich Scientists have now published the results in the journal PLOS ONE. In 2015 they already showed that exposure to particle emissions from heavy…

Offshore wind powers ahead as prices drop 30% below nuclear
The cost of offshore wind power in the North Sea is 30% lower than that of new nuclear, writes Kieran Cooke – helped along by low oil and steel prices, reduced maintenance and mass production. By 2030 the sector is expected to supply 7% of Europe's electricity. Output from the Dogger Bank project will be 1.2…

Hummingbird vision wired to avoid high-speed collisions
Hummingbirds are among nature's most agile fliers. They can travel faster than 50 kilometres per hour and stop on a dime to navigate through dense vegetation.Now researchers have discovered that the tiny birds process visual information differently from other animals, perhaps to handle the demands of their extreme aerial acrobatics."Birds fly faster than insects and…

Trees rely on a range of strategies to hunt for nutrient hot spots
On the surface, trees may look stationary, but underground their roots — aided by their fungal allies — are constantly on the hunt and using a surprising number of strategies to find food, according to an international team of researchers.The precision of the nutrient-seeking strategies that help trees grow in temperate forests may be related…

A battery inspired by vitamins
Harvard researchers have identified a whole new class of high-performing organic molecules, inspired by vitamin B2, that can safely store electricity from intermittent energy sources like solar and wind power in large batteries.The development builds on previous work in which the team developed a high-capacity flow battery that stored energy in organic molecules called quinones…

WSU researchers determine key improvement for fuel cells
Washington State University researchers have determined a key step in improving solid oxide fuel cells (SOFCs), a promising clean energy technology that has struggled to gain wide acceptance in the marketplace.The researchers determined a way to improve one of the primary failure points for the fuel cell, overcoming key issues that have hindered its acceptance.…

New discoveries about photosynthesis may lead to solar cells of the future
For the first time, researchers have successfully measured in detail the flow of solar energy, in and between different parts of a photosynthetic organism. The result is a first step in research that could ultimately contribute to the development of technologies that use solar energy far more efficiently than what is currently possible.For about 80…

Glacial retreats linked to oceanic warming
A new study has found for the first time that ocean warming is the primary cause of retreat of glaciers on the Antarctic Peninsula. The Peninsula is one of the largest current contributors to sea-level rise and this new finding will enable researchers to make better predictions of ice loss from this region.The research, by…

Calcification: Does it pay off in the future ocean?
An international research team has calculated the costs and benefits of calcification for phytoplankton and the impact of climate change on their important role in the world's oceans.Single-celled phytoplankton play an important role in marine biogeochemical cycling, in marine food webs and in the global climate system. Coccolithophores are a particular group that cover themselves…

Ptarmigan in Colorado have varied reproduction, not likely linked to warming trends
Animals that live at high elevations are often assumed to be at risk for extinction as habitats warm and change. But a new study led by Colorado State University researchers found that ptarmigan, which live in cold ecosystems, are not strongly affected by fluctuations in seasonal weather at two populations studied in Colorado.The results, published…
