New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
About 90 percent of precipitation over land depends on the formation of ice crystals in clouds, which fall down due to their increasing weight. But water in…
Scientists from WCS (Wildlife Conservation Society), The Nature Conservancy, and several partners in Brazil and Peru have produced a geographic information…
Because H atoms are very light, they can easily overcome a planet's gravitational force and permanently escape into interplanetary space. The ongoing…
Fully developed tropical cyclones — variously called hurricanes, typhoons or cyclones, depending on their region–can grow as wide as several hundred miles…
“It looks like a triple whammy–a warm ocean, a warm atmosphere, and a wind pattern all working against the ice in the Arctic,” said NSIDC director Mark…
Completed in 2011, the core is packed with information, but it's also packed with noise and error, making the climate story hard to read. Figuring out whether…
New research published in the journal Nature Geosciences shows that the Bay of Bengal, located in the northeastern Indian Ocean, also hosts a “dead zone” of an…
AIM studies noctilucent clouds in order to better understand the mesosphere, and its connections to other parts of the atmosphere, weather and climate. We…
Hydrogenation is a chemical process that transforms liquid vegetable oil to a solid or semisolid state – useful for creating food products like vegetable…
Tornadoes caused the deaths of at least five people in northern Alabama. Storms also took the lives of two people in Tennessee.
A new study published in Geology uses pockets of melts trapped within crystals to understand the conditions occurring beneath volcanoes before explosive…
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tokage's remnants in the South…
When algae cells run out of nutrients and start to die, they clump together and sink as marine snow. The algae and its marine snow aggregates can serve as a…
A key glacier in Antarctica is breaking apart from the inside out, suggesting that the ocean is weakening ice on the edges of the continent.
Ice observations recorded in the ships’ logbooks of explorers such as the British Captain Robert Scott and Ernest Shackleton and the German Erich von Drygalski…
The study, led by Brown University researchers, used seismic monitoring stations to create a sonogram-like image of the crust beneath the southern U.S., near…
