Ohio University researchers announced a new species of mammal from the Age of Dinosaurs, representing the most complete mammal from the Cretaceous Period of continental Africa, and providing tantalizing insights into the past diversity of mammals on the planet.
Every day, people share a dizzying amount of information about local communities online. They talk about whether their neighbors are friendly, how well the buses run, what kinds of restaurants are in an area, and much, much more. A new study shows how we can sort through this vast trove of digital data to improve cities and people's quality of life.
A team led by a conservation biologist from the University of Kent has successfully relocated threatened Seychelles paradise flycatchers (Terpsiphone corvina) to a different island to help prevent their extinction. Four females and two males were caught on Denis Island and taken to Curieuse Island, where they joined 11 males and nine females who were moved there from La Digue Island at the end of last year. Four weeks after that release, the first birds had nested, with the first chick recently fledged.
Rainy weather is becoming increasingly common over parts of the Greenland ice sheet, triggering sudden melting events that are eating at the ice and priming the surface for more widespread future melting, says a new study. Some parts of the ice sheet are even receiving rain in winter -- a phenomenon that will spread as climate continues to warm, say the researchers.
An international team of researchers, which includes scientists from McMaster's School of Geography & Earth Sciences, NASA, and others, is tackling one of the biggest problems of space travel to Mars: what happens when we get there?
Dinosaurs were unaffected by long-term climate changes and flourished before their sudden demise by asteroid strike.
A team of scientists from the UK and China have uncovered new evidence, using recently discovered 25-million-year-old fossilized palm leaves, that Tibet's geography was not as 'high and dry' as previously thought.
Those of us who drive regularly are keenly aware of gas prices and their daily fluctuations. Many of the factors that influence the price per gallon -- the cost of crude oil, regional taxes and processing and transportation charges -- affect all pumps in a given area. Why then do some stations charge more for fuel than others in the same general geographic location?
Two Canadian biologists propose a better way to assess the conservation value of North American old-growth forests -- using lichens, sensitive bioindicators of environmental change. Old-growth forests are usually defined by tree age, but the authors argue this overlooks the importance of biodiversity in those habitats. Lichens are the ideal candidates to measure this biodiversity. Scorecards with suites of lichens specific to these forests can be developed for use by conservation biologists and forest managers.
Wet winters no longer predict possible relief from severe wildfires for California. Now, fuel buildup from decades of fire suppression in the 20th century plus rising temperatures from climate change means any year may have large fires, no matter how wet the previous winter, according to a new study to be published online March 4 in the Proceedings of the National Academy of Sciences.
