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.
Geodesists from the University of Bonn have remeasured the size of the Earth in a long lasting international cooperation project.
The blue planet is accordingly some millimeters smaller than up to now assumed. The results are important, for example, to be able to demonstrate a climate contingent rise in sea level.
A Cardiff University research collaboration is working to recycle precious metals from road dusts and vehicle exhausts to create greener energy.
The innovative research by scientists from the School of Earth, Ocean and Planetary Science working with the University of Birmingham is to be featured at the Royal Society Summer Science Exhibition (2-5 July).
High Arctic ponds -- the most common source of surface water in many polar regions -- are now beginning to evaporate due to recent climate warming, say two of Canada’s leading environmental scientists.
John Smol (Professor of Biology at Queen’s University and holder of the Canada Research Chair in Environmental Change) and Marianne Douglas (Professor of Earth and Atmospheric Sciences and Director of the Canadian Circumpolar Institute at the University of Alberta) will publish their startling conclusions next week in the Proceedings of the National Academy of Sciences (PNAS).
For the first time, a team of experts is preparing to create tsunami in a controlled environment in order to study their effects on buildings and coastlines - ultimately paving the way for the design of new structures better able to withstand their impact.
Dr Tiziana Rossetto, UCL Department of Civil & Environmental Engineering, unveiled plans to develop an innovative new tsunami generator capable of creating scaled-down versions of the devastating waves. The UCL team will be working with marine engineering specialists HR Wallingford (HRW) throughout the project.
Research has uncovered alarming evidence that high Arctic ponds, many which have been permanent bodies of water for thousands of years, are completely drying out during the polar summer. These shallow ponds, which dot the Arctic landscape, are important indicators of environment change and are especially susceptible to the effects of climate change because of their low water volume.
