light Virtual 'UniverseMachine' sheds light on galaxy evolution By feedproxy.google.com Published On :: 2019-09-04T07:00:00Z Full Text:How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has long been a puzzle, but a University of Arizona-led team of scientists is one step closer to finding answers, thanks to supercomputer simulations. Observing real galaxies in space can only provide snapshots in time, so researchers who study how galaxies evolve over billions of years need to use computer simulations. Traditionally, astronomers have used simulations to invent theories of galaxy formation and test them, but they have had to proceed one galaxy at a time. Peter Behroozi of the university's Steward Observatory and colleagues overcame this hurdle by generating millions of different universes on a supercomputer, each according to different physical theories for how galaxies form. The findings challenge fundamental ideas about the role dark matter plays in galaxy formation, the evolution of galaxies over time and the birth of stars. The study is the first to create self-consistent universes that are exact replicas of the real ones -- computer simulations that each represent a sizeable chunk of the actual cosmos, containing 12 million galaxies and spanning the time from 400 million years after the Big Bang to the present day. The results from the "UniverseMachine," as the authors call their approach, have helped resolve the long-standing paradox of why galaxies cease to form new stars even when they retain plenty of hydrogen gas, the raw material from which stars are forged. The research is partially funded by NSF's Division of Physics through grants to UC Santa Barbara's Kavli Institute for Theoretical Physics and the Aspen Center for Physics.Image credit: NASA/ESA/J.

light Fuel produced from sunlight, CO2 and water: an alternative for jet fuel? By ec.europa.eu Published On :: Thu, 08 Sep 2016 10:12:34 +0100 Water and carbon dioxide (CO2) can be converted into ‘solar thermochemical fuel’ using energy from the sun and very high temperatures. A new study has analysed the production of this fuel and found that, under favourable future conditions, costs could be as little as €1.28 per litre, with close to zero life-cycle greenhouse gas (GHG) emissions. Although suitable as a substitute for any hydrocarbon fuel, it could be particularly useful as a much-needed alternative for energy-dense jet fuel. Full Article
light Kerbside waste-collection schemes may need optimisation, highlights Portuguese study By ec.europa.eu Published On :: Thur, 08 March 2018 9:23:19 GMT A new analysis of waste recycling systems in Portugal highlights where kerbside (edge of pavement) collection systems could be optimised, to decrease their environmental impact. In this case, researchers found that the kerbside system was less favourable economically and environmentally due to more packaging and more fuel consumption per tonne of waste, compared to a system where recyclable materials are deposited by residents in large containers. But the researchers suggest that measures such as re-usable boxes and efficient collection routes could help to mitigate the impact of kerbside collection. While there is an environmental impact from waste collection, processing and disposal, this study only focused on the collection phase. Full Article

light New tool developed to highlight and help prevent declines in freshwater biodiversity By ec.europa.eu Published On :: Thu, 28 May 2015 9:23:19 GMT Biodiversity is declining in freshwater ecosystems across the globe, a new study has shown. The researchers created a mathematical model, called GLOBIO- aquatic, which builds a picture of the threats to the biodiversity of rivers, lakes and wetlands that are posed by a variety of human activities. The most crucial of these are land-use changes, nutrient and chemical pollution, and disturbances to the water cycle — which could be from infrastructure such as dams, or from climate change. The authors hope that the model will help policymakers identify regions which are most at risk from these pressures. Full Article
light Artificial light at night — the impact on plants and ecology By ec.europa.eu Published On :: Wed, 04 May 2016 12:34:56 GMT Artificial light — such as street lighting and passing car headlights — has an impact on plants. A new study suggests there could also be broader implications for the interactions of herbivores and pollinators. The study highlights that disrupting seasonal light cues with artificial light has far-reaching effects, including: mismatches in timing with herbivores; altering the development of agricultural crops; inhibiting flowering in wild species; decreasing periods of darkness necessary for plant repair from environmental pollutants; and causing barriers to nocturnal pollinator species.

Artificial light affects bat species differently and the activity of species normally more sensitive to light were affected less by the new LED street lamps than by traditional mercury lamps. Use of LEDs may, therefore, help to reduce the impacts of outdoor lighting on light-sensitive bats, if used at an appropriate level. Full Article
light Farmland abandonment risk highlighted in new UK study By ec.europa.eu Published On :: Thur, 04 May 2017 9:23:19 GMT Traditional, high-nature-value (HNV) grasslands are at risk of being abandoned by farmers in the future — in turn, risking the wildlife they support, warns a new UK study. Farmers interviewed by the researchers had weak motivations to protect grasslands, as they felt that financial incentives for conservation are low and that traditional management practices are inconvenient. More dialogue between farmers and conservationists could be part of the solution, the study suggests. Full Article
