Hitomi Mission Glimpses Cosmic 'Recipe' for the Nearby Universe
November 13, 2017 11:52 AM - NASA/Goddard Space Flight Center

Before its brief mission ended unexpectedly in March 2016, Japan's Hitomi X-ray observatory captured exceptional information about the motions of hot gas in the Perseus galaxy cluster. Now, thanks to unprecedented detail provided by an instrument developed jointly by NASA and the Japan Aerospace Exploration Agency (JAXA), scientists have been able to analyze more deeply the chemical make-up of this gas, providing new insights into the stellar explosions that formed most of these elements and cast them into space.

Team Finds First Wild Alligator Snapping Turtle in Illinois Since 1984
November 13, 2017 11:48 AM - University of Illinois at Urbana-Champaign

Researchers report the first sighting in 30 years of a wild alligator snapping turtle in Illinois. The discovery may be a sign of hope for this state-endangered species, or the animal could be the last of its kind to have survived in Illinois without human intervention, the researchers say.

Learning from Photosynthesis
November 13, 2017 11:43 AM - Arizona State University

The green sulfur bacterium makes its home in the chilly waters of the Black Sea. To eek out its lonely existence, this life form scavenges energy from the feeble sunlight available to it at a depth of over 250 feet.

App 'Trained' to Spot Crop Disease, Alert Farmers
November 13, 2017 11:30 AM - , SciDevNet

A team of scientists has received US$100,000 grant to refine a mobile application (app) that uses artificial intelligence to diagnose crop diseases, and aims to help millions of African smallholders.

Urban Trees are Growing Faster Worldwide
November 13, 2017 11:23 AM - Technical University of Munich (TUM)

Trees in metropolitan areas have been growing faster than trees in rural areas worldwide since the 1960s. This has been confirmed for the first time by a study on the impact of the urban heat island effect on tree growth headed by the Technical University of Munich (TUM). The analysis conducted by the international research team also shows that the growth of urban trees has already been exposed to changing climatic conditions for a long period of time, which is only just beginning to happen for trees in rural areas.

Global carbon dioxide emissions projected to rise after three stable years
November 13, 2017 09:18 AM - Future Earth

By the end of 2017, global emissions of carbon dioxide from fossil fuels and industry are projected to rise by about 2% compared with the preceding year, with an uncertainty range between 0.8% and 3%. The news follows three years of emissions staying relatively flat.

York University research shows insecticide-laden seeds can disorient migrating songbirds
November 13, 2017 08:32 AM - York University

Songbirds exposed to widely used insecticides during migration pit stops on farmland could lose significant body weight and become disoriented, research by York University and the University of Saskatchewan (U. of S.) has found.

The researchers exposed white-crowned sparrows on spring migration to realistic doses of two different insecticides – imidacloprid, a neonicotinoid, and chlorpyrifos, an organophosphate – to see the effects on migratory activity, orientation and body mass.

Designing the climate observing system of the future
November 13, 2017 08:32 AM - NOAA (National Oceanic and Atmospheric Administration)

A targeted expansion of climate observing systems could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits, according to a new paper published today in the online journal Earth’s Future. Better observations would provide decision makers information they need to protect public health and the economy in the coming decades, the scientists say.

Venkatachalam Ramaswamy, director of NOAA’s Geophysical Fluid Dynamics Laboratory, said that improving our ability to predict and plan for droughts, floods, extreme heat events, famine, sea level rise and changes in freshwater availability is likely to  yield significant savings  each year.

Bad Break: Osteoporosis-Related Bone Fractures Linked to Air Pollution
November 10, 2017 02:06 PM - Columbia University Mailman School of Public Health

Exposure to air pollution is associated with osteoporosis-related loss of bone mineral density and risk of bone fractures, according to a new study by researchers at Columbia University’s Mailman School of Public Health. Their findings are published in The Lancet Planetary Health.

Melting ice sheets will have global impact on ocean tides
November 10, 2017 02:02 PM - Bangor University

Whilst it is widely accepted that sea level is rising because of the melting of the massive sheets covering Greenland and Antarctica, a new paper in the Journal of Geophysical Research: Oceans, by scientists at Bangor University in collaboration with Harvard and Oregon State Universities in the US, and McGill University in Canada, shows that the impact of the melting of these ice sheets will go far beyond just changing water levels. It could have further reaching impacts on global climate.
