Crowdsourcing is used for everything from raising funds to locating the best burger in town. The practice of enlisting a large group of people to provide a service, information or a contribution to a project--most often via the internet--is a defining feature of our era.

CAMBRIDGE, Mass. -- Utility companies or others planning to install renewable energy systems such as solar and wind farms have to decide whether to include large-scale energy storage systems that can capture power when it's available and release it on demand. This decision may be critical to the future growth of renewable energy.
In the race towards the discovery of a ninth planet in our solar system, scientists from around the world strive to calculate its orbit using the tracks left by the small bodies that move well beyond Neptune. Now, astronomers from Spain and Cambridge University have confirmed, with new calculations, that the orbits of the six extreme trans-Neptunian objects that served as a reference to announce the existence of Planet Nine are not as stable as it was thought.
The Milky Way, the brilliant river of stars that has dominated the night sky and human imaginations since time immemorial, is but a faded memory to one third of humanity and 80 percent of Americans, according to a new global atlas of light pollution produced by Italian and American scientists.
Light pollution is one of the most pervasive forms of environmental alteration. In most developed countries, the ubiquitous presence of artificial lights creates a luminous fog that swamps the stars and constellations of the night sky.
HOUSTON -- (June 9, 2016) -- Astronomers searching for the galaxy's youngest planets have found compelling evidence for one unlike any other, a newborn "hot Jupiter" whose outer layers are being torn away by the star it orbits every 11 hours.
Intermodal transportation -- which uses a combination of transportation modes, such as trucks, trains and ships, to move everyday goods -- is the backbone of many supply chains, and while the industry is seeing tremendous growth, it also faces a severe container capacity shortage.
Ting Luo, a PhD candidate in operations management in the Naveen Jindal School of Management, recently examined how managers in intermodal marketing companies should use dynamic forecasting to coordinate daily operations, enhance efficiency and improve profitability.
Data from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) were used to estimate rainfall from Tropical Storm Colin over a two day period before it dissipated.
Athens, Ga. - A new study provides the first evidence that links melting ice in Greenland to a phenomenon known as Arctic amplification--faster warming of the Arctic compared to the rest of the Northern Hemisphere as sea ice disappears.
The findings show that the predicted effects of Arctic amplification, as described in previous studies, occurred over northern Greenland during summer 2015, including a northern swing of the jet stream that reached latitudes never before recorded in Greenland at that time of year.
Observing very distant objects in the universe is a challenge because the light which reaches us is extremely faint. Something similar occurs with objects which are not so distant but have very low surface brightness. Measuring this brightness is difficult due to the low contrast with the sky background. Recently a study led by the Instituto de Astrofísica de Canarias (IAC) set out to test the limit of observation which can be reached using the largest optical-infrared telescope in the world: the Gran Telescopio CANARIAS (GTC).
Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Arctic amplification.

At the center of a galaxy cluster, 1 billion light years from Earth, a voracious, supermassive black hole is preparing for a chilly feast.
Astronomers from Cardiff University are part of an international team that has, for the first time, detected billowy clouds of cold, clumpy gas streaming towards a supermassive black hole at speeds of up to 800,000 miles per hour and feeding into its bottomless well.
The observation, which was aided by the work of Dr Timothy Davis from the School of Physics and Astronomy, marks the first direct evidence to support the theory that black holes feed on clouds of cold gas.
The new ALMA observation is the first direct evidence that cold dense clouds can coalesce out of hot intergalactic gas and plunge into the heart of a galaxy to feed its central supermassive black hole. It also reshapes astronomers' views on how supermassive black holes feed, in a process known as accretion.
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has witnessed a never-before-seen cosmic weather event -- a cluster of towering intergalactic gas clouds raining in on the supermassive black hole at the center of an elliptical galaxy one billion light-years from Earth.
