When it comes to monarchs, fall migration matters — ScienceDaily

Scientists studying monarch butterflies have traditionally focused on two sources for their decline — winter habitat loss in Mexico and fewer milkweed plants in the Midwest. New research conducted by Michigan State University and published in Proceedings of the National Academy of Sciences, however, shows that a critical piece of the butterfly’s annual cycle was missing — the fall migration. By focusing on this southerly trek, as well as changing the scale at which winter populations are examined, scientists reveal…

Testing space batteries for cleaner skies

This test overcharge of a lithium-ion battery cell at CEA test facilites in France resulted in an explosion. Credit: ESA/Airbus Engineers descended into bunkers to test space batteries to destruction – through overheating, overcharging, short circuits and even by shooting them with bullets. The three-year test campaign is helping assess the risk of abandoned satellites exploding in orbit due to catastrophic battery reactions. Extreme ‘abuse’ testing of the current generation of lithium-ion batteries for space took place in the test…

Moon’s dayside water molecules migrate over the course of a day — ScienceDaily

Using the Southwest Research Institute-led Lyman Alpha Mapping Project (LAMP) aboard NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have observed water molecules moving around the dayside of the Moon. A paper published in Geophysical Research Letters describes how LAMP measurements of the sparse layer of molecules temporarily stuck to the surface helped characterize lunar hydration changes over the course of a day. Up until the last decade or so, scientists thought the Moon was arid, with any water existing mainly as…

‘Upcycling’ plastic bottles could give them a more useful second life — ScienceDaily

Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a recycling process that transforms single-use beverage bottles, clothing, and carpet made from the common polyester material polyethylene terephthalate (PET) into more valuable products with a longer lifespan. Their research, published February 27 in the journal Joule, could help protect oceans from plastic waste by jumpstarting the recycled plastics market. PET is strong but lightweight, resistant to water, and shatterproof — properties that make it extremely…

Tiny fibers create unseen plastic pollution — ScienceDaily

While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem. “These materials, during production, processing and after use, break down into and release microfibers that can now be found in everything and everyone,” said Melik Demirel, Lloyd and Dorothy Foehr Huck Endowed…

Ship disasters avoided with big data statistics techniques

New statistical methods should make it possible to sound the alarm before faults on large ships happen, say Morten Stakkeland and Ingrid Glad. Credit: Yngve Vogt Companies can save millions by using advanced statistical methods to extract information from large amounts of collected data. One company that has adopted this new way of thinking is the international industrial group ABB. They work closely with statisticians at the University of Oslo in Norway to enable shipping companies to save millions on…

May explain why women more likely to stay mentally sharp in later years — ScienceDaily

Time wears differently on women’s and men’s brains. While the brain tends to shrink with age, men’s diminish faster than women’s. The brain’s metabolism slows as people grow older, and this, too, may differ between men and women. A new study from Washington University School of Medicine in St. Louis finds that women’s brains appear to be about three years younger than men’s of the same chronological age, metabolically speaking. The findings, available online the week of Feb. 4 in…

Strategies for growing biomass for fuel can have economic, ecological and environmental benefits — ScienceDaily

In efforts to curb our use of greenhouse gas-generating fossil fuels, plant-based biofuels are among the top contenders as alternative liquid energy sources for transportation. However, strategies to produce high yields of biomass for fuels are not a one-size-fits-all proposition, according to a study led by UC Santa Barbara professor of ecology David Tilman. “It is difficult to make a biofuel that actually has environmental benefits,” said Tilman, a faculty member in the Bren School of Environmental Science & Management,…

Predictive model for accurate electrical grid mapping

DIMITRY GERSHENSON    BRANDON ROHRER    ANNA LERNER When planning connectivity deployments in emerging markets, it’s important to have a clear picture of where existing power lines are placed. This information helps us make better decisions about where to focus our efforts, how we design the network, and how we source the equipment we’ll need. When we look for this information in developing countries, however, it is often outdated, inaccurate, or too low resolution to be useful. To find a…

Microbes screened with a new microfluidic process might be used in power generation or environmental cleanup — ScienceDaily

Living in extreme conditions requires creative adaptations. For certain species of bacteria that exist in oxygen-deprived environments, this means finding a way to breathe that doesn’t involve oxygen. These hardy microbes, which can be found deep within mines, at the bottom of lakes, and even in the human gut, have evolved a unique form of breathing that involves excreting and pumping out electrons. In other words, these microbes can actually produce electricity. Scientists and engineers are exploring ways to harness…
