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…

Marine Fossils Enhance Climate Change Predictions Efforts

A study of the ancient Mediterranean Sea will help to produce more accurate predictions of climate change.

A team led by Royal Holloway geologist Dr Michal Kucera will map sea-surface temperature of the Mediterranean over past millennia. The data will provide a new target to test the computer models on which our predictions of climate change are based.

We currently make climate change predictions using mathematical models developed using climate records of the last two centuries. T

Greenland Ice Sheet Melting Faster: New Findings Unveiled

New measurements show that the flow of ice in the Greenland ice sheet has been accelerating since 1996 during the summer melt season. The results suggest that the ice sheet may be responding more quickly to the warming climate than previously thought.

In an article published in Science magazine’s online Sciencexpress June 7, Jay Zwally, an ICESat Project scientist at the NASA Goddard Space Flight Center, Greenbelt, Md., Waleed Abdalati, a Polar Program scientist at NASA Headquarters, W

Rutgers Scientists Develop High-Protein Corn for Global Needs

A new approach without the controversial biotechnology used in GMOs

Rutgers geneticists have devised a new approach to create a more nutritious corn without employing the controversial biotechnology used in genetically modified foods. Instead of adding foreign DNA to the corn, the researchers increased the plant’s ability to produce more of its own naturally occurring protein by adjusting the genetic signals that control the process. The result is a more nutritious and natural fo

Climate Change Could Surpass CFCs in Ozone Loss by 2030

While industrial products like chlorofluorocarbons are largely responsible for current ozone depletion, a NASA study finds that by the 2030s climate change may surpass chlorofluorocarbons (CFCs) as the main driver of overall ozone loss.

Drew Shindell, an atmospheric scientist from NASA’s Goddard Institute for Space Studies (GISS) and Columbia University, N.Y., finds that greenhouse gases like methane and carbon dioxide are changing the climate in many ways. Some of those effects include wat

Invisible Polymer Film Enhances Grass Recovery After Mining

To help the nature to recover from harmful impacts of the mining industry, Svetlana Mesyats and her team from the Geological Institute of the Kola Research Center RAS offer the method, which implies the application of a thin invisible polymeric film onto the soil surface and provides for a fast and successful minesite recultivation.Polymer Protects Grass

New Technique Predicts Storms Weeks in Advance

The catastrophic flooding in Jakarta in February this year could have been predicted nearly 3 weeks in advance with a new technique being developed by Dr Matt Wheeler and colleagues at the Bureau of Meteorology Research Centre in Australia.

The flooding was caused by large waves of air and clouds, so called Madden-Julian Oscillations (MJOs). Using satellite data Dr Wheeler and co-workers are able to predict the occurrence of MJOs, which take about one month to move across the Indian basin a

Protective Storm in Space – a new explanation for the death of the dinosaurs

A shower of matter from space millions of years ago could have led to drastic changes in the Earth’s climate, followed by the extinction of life on a massive scale, which also killed off the dinosaurs. This at least is a theory put forward by scientists from the University of Bonn. Normally, the solar wind acts as a shield against showers of cosmic particles, which prevents too many energy-rich particles from raining down on our atmosphere. Since 1997 scientists from Bonn, funded by the German Resea

Sustainable Resource Management for Southeast Asia’s Future

The use of key resources such as forests, fisheries and energy is likely to be unsustainable and threaten the ability of SE Asia to build an environmentally and economically stable future in the face of global change, say a group of international scientists meeting in Bali this week.

In the 1980s the rates of deforestation in Southeast Asia ranged between 60,000 hectare per year in Cambodia and 600,000 hectare per year in Indonesia. Twenty years later it became uncontrollable with larger ran

New Research Validates Increased Greening Trends in the North

Greening seems to have increased during the 1980s and 1990s in the northern hemisphere from the arctic regions down to the 35th parallel of latitude (roughly southern Europe). This has been shown by measurements from space satellites. Some observers, however, have doubted the reliability of these measurements. In the latest issue of Science, a research team from the Institute for Climatic Impacts Research in Potsdam, the Max Planck Institute for Biogeochemistry in Jena, and Lund University presents n

Rising Temperatures Tied to Flowers’ Earlier Bloom

The results of a new study suggest that rising temperatures are leaving a mark on the world. According to a report published in the current issue of the journal Science, the first flowering of plants in Britain has changed by as much as 55 days over the past few decades in response to warmer weather. The results, the scientists say, are the “strongest biological signal yet of climatic change.”

Identifying VOCs Behind Houston’s Ozone Pollution Sources

Findings may lead to more effective regulations for protecting public health

Using data from one of the most comprehensive U.S. air pollution studies ever conducted, scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have identified specific volatile organic compounds (VOCs) as key sources of excess ozone smog in industrial areas of Houston, Texas — which appear to be different from traditional sources of ozone pollution in typical urban areas around the co

Marsquake Sensors: Uncovering Water Beneath Martian Surface

Researchers at Imperial College London have just begun a 5-year project to design and build tiny earthquake measuring devices to go to Mars on the 2007 NetLander mission.
Unlike the instruments on next year`s European Mars Express/Beagle II mission, the Marsquake sensors will be the first to look deep inside the planet.

The internal structure of Mars is a key to understanding some fundamental questions about the planet including whether life ever existed there.

The sensors are c

Scientists Simulate Martian Environment for Space Research

Scientists at the University of Leicester’s Space Research Centre are recreating the hostile environment found on Mars in their laboratory, with a device known as the Martian Environment Simulator (MES). The machine reproduces the temperature, air pressure and unbreathable atmosphere known to exist on Mars. The MES is currently being used to test equipment on the Beagle 2 lander, part of the European Space Agency’s Mars Express Spacecraft and due to arrive on Mars during Christmas 2003. The chance o

Unlocking Forest Tree Survival: Insights from New Research

Species extinction or `biodiversity loss` has accelerated at an alarming rate over the past century. Although much of the blame has been laid at the door of human activity, biologists are looking at the factors that influence how species-particularly similar species-co-exist, in their efforts to better understand how the balance of species can be maintained.

New research into forest trees by Dr Colleen Kelly of the Division of Ecology and Biodiversity at the University of Southampton has sho

Can Airborne Microbes Affect Weather? New Research Launches

Researchers from the University of East London (UEL) have embarked on a project to investigate the ecology of the atmosphere, one of the last great frontiers of biological exploration on Earth. In an eighteen-month pilot project launched today, a team of microbiologists led by Dr Bruce Moffett aims to discover whether airborne microbes play an active role in forming clouds and causing rain to fall.

The researchers are using a revolutionary `cyclonic cloud catcher`, based on vacuum cleaner te
