Desert Climate in Western U.S. Influenced By Ancient Water Cycle
The climate change we are currently experiencing, while disconcerting and increasingly uncomfortable, is not unprecedented when viewed through the historical prism of life on Earth. A study led by researchers from Texas A&M University’s Department of Oceanography looks back at the water cycle that affected the Western United States in an era dating back some…
Is Corn Syrup Killing the Honeybees?
A trio of recent studies faults a common family of corn pesticides for disorienting honeybees, potentially leading to colony collapse disorder. The German chemical company Bayer, which manufactures the pesticides, disagrees.
Small-Scale Fuel Cell Designed for Residential Use
Individual homes could soon be powered with their own solid oxide fuel cell systems, thanks to a breakthrough in performance. The new system, from the Department of Energy’s Pacific Northwest National Laboratory (PNNL), achieves up to 57% efficiency – half as good again as previous versions of the same size. It uses methane as fuel,…
Reimagining Evolution: Most Mutations Come From Dad
Humans inherit more than three times as many mutations from their fathers as from their mothers, and mutation rates increase with the father’s age but not the mother’s, researchers have found in the largest study of human genetic mutations to date. The study, based on the DNA of around 85,000 Icelanders, also calculates the rate…
Dung Beetles Use Milky Way as GPS
Birds and humans use stars to navigate, but can insects map their routes? For dung beetles, a new study says the answer is yes. The African insects appear to find their way via the Milky Way. It’s the first evidence that any insect can orientate themselves with the sky, and the first evidence that any…
Researchers Find New Atomic Structures
Drawing on powerful computational tools and a state-of-the-art scanning transmission electron microscope, a team of materials science and engineering researchers has discovered a new nanometer-scale atomic structure in solid metallic materials known as metallic glasses. Published in the journal Physical Review Letters, the findings fill a gap in researchers’ understanding of this atomic structure. This…
