Uneven Nutritional Payoffs for Marine Predators Revealed

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…

Tiny polyps gorge themselves to survive coral bleaching

Certain species of coral have surprised researchers by showing an unexpectedly successful approach towards survival when seriously bleached. Their innovative strategy is gluttony.

The discovery, derived from experiments on coral reefs in Hawaii , provides new insights into how these tiny animals face a multitude of environmental threats. The report by Ohio State University researchers is published in the current issue of the British journal Nature.

Ferment and cook beans for wind-free nutrition

Research News from the Journal of the Science of Food and Agriculture

Fermenting beans and then cooking them not only reduces the majority of the soluble fibre that leads to flatulence, but also enhances their nutritional quality. Now we know which bacteria are important for the fermentation, reveal findings published online today in the SCI’s Journal of the Science of Food and Agriculture.

Beans are already an important source of nutrients, and many people would eat m

New instrument for atmospheric research

An advanced laser-based instrument to help research into climate change is being developed for one of the world’s leading atmospheric research aircraft.

Professor Paul Kaye, Dr Edwin Hirst and Dr Richard Greenaway at the University of Hertfordshire’s Science and Technology Research Institute (STRI) have been commissioned by the US University Corporation for Atmospheric Research (UCAR) to build the instrument for their new HIAPER (High-performance Instrumented Airborne Platform

NASA Data Enhances Hurricane Landfall Forecasts Using New Models

Data gathered from last year’s NASA hurricane research mission and a NASA satellite have improved tropical storm landfall and storm strength forecasts in computer models.

Ocean surface wind data gathered from NASA’s QuikSCAT satellite were combined with data from aircraft sensors dropped into tropical storms and fed into a new generation weather research and forecasting (WRF) computer model used to predict weather. The researchers in this study also used data from the Nationa

New Mapping Tool Helps Truckers Find Idle Reduction Stations

A new internet-based mapping program is helping truckers find truck stops with idle reduction facilities—on-site systems that can substantially cut fuel use while reducing air emissions.

Idle reduction systems hold great promise for the approximately 500,000 long-haul trucks with sleeper cabs currently operating in the United States. Estimates show idle reduction technologies could reduce diesel fuel use by about 800 million gallons annually, with a potential savings to the trucking

Rare ‘Pristine’ Meteorite Discovered at University of Alberta

The depths of space are much closer to home following the University of Alberta’s acquisition of a meteorite that is the only one of its kind known to exist on Earth! What makes it so rare? The meteorite is ’pristine’ – that is, still frozen and uncontaminated – and so provides an invaluable preserved record of material from when the solar system formed 4.57 billion years ago.

The Tagish Lake Meteorite is carbonaceous chondrite and, as such, represents primitive materia

Diverse Tropical Forests Challenge Metabolic Ecology Models

The complex patterns of tropical forest structure demand more complex explanations

As global change accelerates, quantifying the role of forests in the carbon cycle becomes ever more urgent. Modelers seek simple predictors of forest biomass and carbon flux. Over the last decade, the theory of metabolic ecology generated testable explanations, derived from physical and biochemical principles, for a wide range of ecological patterns. However, in two Ecology Letters articles, Hele

Norway’s First Dinosaur discovered – 2256 metres below the seabed

While most nations excavate their skeletons using a toothbrush, the Norwegians found one using a drill.

The somewhat rough uncovering of Norway’s first dinosaur happened in the North Sea, at an entire 2256 metres below the seabed. It had been there for nearly 200 million years, ever since the time the North Sea wasn’t a sea at all, but an enormous alluvial plane.

It is merely a coincidence that the remains of the old dinosaur now see the light of day again, or more preci

Mars’ New Mineral Record Reveals Early Life Potential

An international team of scientists, including Brown University geologist John Mustard, has created the most comprehensive mineral record of Mars to date. Using data from the European Space Agency’s Mars Express mission, the record shows three distinct geological eras on the Red Planet, with the earliest marked by the presence of water. Results are published in Science.

Mars started out relatively wet and temperate, underwent a major climate shift, and evolved into a cold,

Scientists penetrate fossil magma chamber beneath intact ocean crust — achieving scientific ’first’

PACIFIC OCEAN, approximately 800 km west of Costa Rica¡ªAn international team of scientists aboard the research drilling ship JOIDES Resolution has¡–for the first time¡–recovered black rocks known as gabbros from intact ocean crust. Supported by the Integrated Ocean Drilling Program (IODP), the scientists drilled through the volcanic rock that forms the Earth’s crust to reach a fossil magma chamber lying 1.4 kilometers beneath the seafloor.

Rainfall Erosion: How Climate Change Impacts Earth’s Depths

Human-induced climate change could ultimately influence deep Earth processes

The erosion caused by rainfall directly affects the movement of continental plates beneath mountain ranges, says a University of Toronto geophysicist — the first time science has raised the possibility that human-induced climate change could affect the deep workings of the planet.

“In geology, we have this idea that erosion’s going to affect merely the surface,” says Russell Pysklywec, a professor

Scientists Discover Ancient Magma Chamber Beneath Ocean

International collaboration brings up first samples of hard rock called gabbro in intact ocean crust

Scientists aboard the research drilling ship JOIDES Resolution have, for the first time, drilled into a fossil magma chamber under intact ocean crust. There, 1.4 kilometers beneath the sea floor, they have recovered samples of gabbro: a hard, black rock that forms when molten magma is trapped beneath Earth’s surface and cools slowly.

Coastal Alabama and Mississippi Launch Massive Marsh Planting

An unprecedented marsh gardening project, spanning two states and utilizing the talents of many agencies, is ready to begin this spring. Headed by Dr. Just Cebrian, Senior Marine Scientist at the Dauphin Island Sea Lab, this ambitious “greening of the estuaries” seeks to establish new, or rehabilitate existing, marsh sites.

In 2002, the Mobile Bay National Estuary Program’s Comprehensive Conservation and Management Plan was approved by the Environmental Protection Agency. Thi

Massive Rivers Discovered Under Antarctica’s Ice Shelf

British scientists have discovered rivers the size of the Thames in London flowing hundreds of miles under the Antarctica ice shelf by examining small changes in elevation, observed by ESA’s ERS-2 satellite, in the surface of the oldest, thickest ice in the region, according to an article published in Nature this week.

The finding, which came as a great surprise to the scientists, challenges the widely held assumption that subglacial lakes evolved in isolated conditions for severa
