A NASA researcher has developed a new method to anticipate food shortages brought on by drought. Molly Brown of NASA’s Goddard Space Flight Center in Greenbelt, Md., and her colleagues created a model using data from satellite remote sensing of crop growth and food prices.
Ethanol is 'oversold' a new report says.
The future of biofuels is not in corn, says a new report released today by Food & Water Watch. The corn ethanol refinery industry, the beneficiary of new renewable fuel targets in the proposed energy legislation as well as proposed loan guarantee subsidies in the 2007 Farm Bill, will not significantly offset U.S. fossil fuel consumption without unacceptable environmental and economic consequences.
Primetime crime drama meets reality in forensic research taking place at the Midwest Forensics Resource Center at Iowa State University.
Ames Laboratory scientists are using the new Direct Analysis in Real Time mass spectrometry interface, which has made a guest appearance on the popular crime show "CSI: New York," to build a library of ink mass spectra using samples from the US Secret Service. The mass spectra library will help identify inks on fraudulent documents and other crime evidence.
You have a greater possibility of losing weight if you eat a diet that is high in foods like lentils that release energy slowly once they have been consumed, rather than one that is high in foods that rapidly release sugar into the blood stream such as white bread, a Cochrane Systematic Review has concluded.
Scientists say that using data from the Mars Express mission and numerical models they can determine how the orbit of Mars around the Sun accounts for the origin and perennial occurrence of water ice at the Martian South Pole.
Many earthquakes in the deep ocean are much smaller in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution have found new evidence that the fragmented structure of seafloor faults, along with previously unrecognized volcanic activity, may be dampening the effects of these quakes.
A team of led by Norwich BioScience Institutes Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment.
Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. They can also repress growth when their environment is not favorable. This involves many complex signalling pathways which are integrated by the plant growth hormone gibberellin.
NASCAR guys may be on to something. It turns out that drafting, even on busy highways, could cut congestion, save fuel and cut greenhouse gas emissions, according to research published today in the International Journal of the Environment and Pollution.
As populations grow and the number of vehicles on the roads in cities and motorways across Europe, North America and the developing world, rises, traditional ways of tackling the problem, such as simply building more roads or improving public transport are becoming less and less effective.
Indonesia’s Mount Gamkonora volcano is spewing hot ash and smoke into the air, as seen in this image taken by the MERIS instrument aboard ESA’s satellite Envisat, causing more than 8000 people to be evacuated amid fears of an imminent eruption, according to officials.
Engineers at the University of Hertfordshire have developed the first hydrogen-powered racing car which they will race this weekend.
A £5,000 grant from the Royal Society of Chemistry has made it possible for John Goddard and James Waters, two PhD students in the University’s new Sustainable Energy Technologies Centre to convert a Formula Student racing car into a hydrogen-powered vehicle.
In Earth's long history, its climate has changed many times. This was because orbit parameters altered, continents and oceans shifted, large asteroids fell and volcanoes began to erupt.
In the last decade of the 20th century, the scientific community began to discuss one more possibility for climatic changes, which are long-term in terms of human history and quick in terms of geological time scale.
Fossilised midges have helped scientists at the University of Liverpool identify two episodes of abrupt climate change that suggest the UK climate is not as stable as previously thought.
The episodes were discovered at a study in Hawes Water in Northern Lancashire, where the team used a unique combination of isotope studies and analysis of fossilised midge heads. Together they indicated where the climate shifts occurred and the temperature of the atmosphere at the time.
From Al Gore's "An Inconvenient Truth" to heated Congressional debates about federal tax incentives for new alternative fuels, the issue of coal's place in supplying America's energy and fuel needs has taken on added importance in recent months.
A research institute at the University of Kentucky, though, has been exploring ways to increase the efficiency of converting coal to liquid fuel well in advance of national discussions of the process.
A team of international researchers has collected the oldest ever recovered DNA samples and used them to show that Greenland was much warmer at some point during the last Ice Age than most people have believed. Their findings also confirm that the whole ice sheet will not melt and bring about the tremendous sea-level rises which have been the subject of so much discussion.
Klyuchevskoy (pronounced Kloo-shef-skoy), a stratovolcano located in the north central region of the Kamchatka Peninsula, is blasting ash up to 32,000 feet in the air, and has diverted air traffic headed toward the Far East. This is the largest eruption to occur in the North Pacific in a decade, and is providing students at the University of Alaska Fairbanks a unique opportunity to collaborate with scientists, as well as state and federal agencies.
