A joint research proposal between University of Warwick scientists at Warwick HRI and researchers in the University’s Department of Politics and International Studies has won a £316,000 grant from the Research Councils’ Rural Economy and Land Use programme for a project on the science and regulation of bio-pesticides.
Consumers, retailers and environmentalists are calling for reductions in the use of chemical pesticides. One potentially environmentally friendly solution is to use so-cal
ESO’s Very Large Telescope Obtains Unique Spectrum of a Meteor
While observing a supernova in a distant galaxy with the FORS instrument on ESO’s Very Large Telescope at the Paranal Observatory (Chile), astronomers were incredibly lucky to obtain serendipitously a high quality spectrum of a very large meteor in the terrestrial atmosphere.
The VLT spectrograph provided a well calibrated spectrum, making it a reference in this field of research. From this spectrum, the temperatu
Scientists are embarking on a project which will explore how global warming is devastating one of the world’s most diverse ecosystems.
One sixth of the world’s coral reefs died due to bleaching in 1998, and the situation is getting worse. Bleaching occurs when tropical seas heat up above there normal maximums, killing the corals.
These events are equally catastrophic for the quarter of all known marine species which make their home in the reefs and for the coastal commun
The fact that each white whale has individual voice is established by Russian scientists conducting research in the White Sea. Differences between white whales’ voices can be used in estimating their number.
“White whale individuals can be distinguished by the sound of voice practically like humans,” – tell V.M. Bel’kovich and S.A. Kreichi from the Shirshov Institute of Oceanology. The scientists observe the animals every year in the White Sea by the Bolshoi Solovetskii Isl
In the nearest future we may witness global cooling in spite of increasing concentration of greenhouse gases in the atmosphere. That can happen, if the following hypothesis is correct: not the growth of greenhouse gases concentration provokes temperature to rise, but vice versa.
It is generally believed nowadays that greenhouse gases are responsible for the growth of temperature of the atmosphere, but that might be wrong. Recent climate change is similar to those regularly developed i
Surgeons at the Cedars-Sinai Institute for Spinal Disorders describe in the August 1 issue of the journal Spine a minimally invasive approach that enables them to perform fusion surgery on the difficult-to-access upper lumbar region of the spine with a reduced risk of serious complications.
“Compared to previous options, this new approach is safer with respect to major blood vessels and abdominal organs,” said John J. Regan, M.D., co-director of the Institute. “The majority of patients expe
When molecules in cells are stimulated by light, they respond by becoming excited and re-emitting light of varying colors (fluorescence) that can be captured and measured by highly sensitive optical equipment.
Now, researchers at Cedars-Sinai Medical Center and the University of Southern California are developing miniaturized spectroscopic instruments and computer software to take a real-time look at biochemical, functional and structural changes occurring within the cells and tissu
High-risk prostate cancer patients who undergo a combination of hormonal therapy, radioactive seed implant (also called brachytherapy) and external beam radiation therapy are shown to have an increased chance of cancer cure, according to a new study published in the August 1, 2004, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.
Historically, high-risk prostate cancer
A Mayo Clinic research team is focusing on a hormone previously identified in the venom of the green mamba snake for the role it may play in a dangerous blood vessel narrowing in stroke patients that can lead to a second stroke, reduced blood flow and brain damage.
Called “cerebral vasospasm,” this common complication of stroke occurs in approximately one-third of patients who experience a ruptured brain blood vessel. Its cause is not known. By discovering a possible role for this
Men who try hypnosis to help them quit smoking are more likely to be successful than women who use the same treatment, according to new research.
A review of 18 studies of hypnosis-based smoking cessation programs found that about 30 percent of men who used such a treatment successfully quit smoking, compared to 23 percent of women.
But the reasons may have more to do with gender differences in quitting smoking in general than reasons associated with hypnosis, said Joseph Gre
Data presented here today at the Academy 2004 meeting of the American Academy of Dermatology demonstrate that tacrolimus ointment is more effective than pimecrolimus cream in the treatment of adult and pediatric patients with atopic dermatitis (AD).
Overall results also revealed that in the same patient populations, both treatments have similar safety profiles including no statistical difference with regard to burning and stinging. These findings were presented by Alan Fleischer, M.
Encouraging trends in the long term success of total ankle replacement were reported in a study presented at the American Orthopaedic Foot and Ankle Society’s (AOFAS) annual summer meeting today.
This study, conducted by Charles Saltzman MD, a Professor of Orthopaedic Surgery and Engineering from the University of Iowa, found total ankle replacement to be an option for patients with severe arthritis. Similar to hip and knee replacement surgeries, total ankle replacement involves removing th
Researchers at the University of Washington will direct the largest study of its kind to explore the connection between air pollution and the No. 1 cause of death in the United States: cardiovascular disease.
“We’re going to be looking at questions vital to our understanding of the health effects of air pollution and cardiovascular disease,” said Dr. Joel Kaufman, principal investigator on the project and associate professor in the Department of Environmental and Occupational Hea
From Mazatlán to Tucson, the National Center for Atmospheric Research (NCAR) is analyzing moisture-laden skies through September as part of the largest study yet of the North American Monsoon. Each year the midsummer arrival of quenching rains plays a vital role in dryland farming, ranching, and wildfire control across the southwest United States and northwest Mexico. The monsoon may also hold useful clues for predicting summer rainfall elsewhere in the United States.
“A long-term go
New York City’s late summer/early fall 2000 mosquito spraying session, designed as an effort to minimize the spread of West Nile virus, did not increase the number of people seeking emergency care for asthma-related problems, according to a study published today in the August issue of the peer-reviewed journal Environmental Health Perspectives (EHP). The study found no correlation between the application of sumithrin—a pyrethroid pesticide—in the 162 residential zip codes sprayed between July and S
Much like moving furniture around to create more space, cells dramatically rearrange their entire genome in order to allow the right genes to be turned on at the right time, new research at the University of North Carolina at Chapel Hill shows.
This extensive chromosomal “remodeling” is accomplished by moving DNA packaging structures called nucleosomes to different spots in the genome. Once a nucleosome is moved from a site, the appropriate gene then can be expressed much more effici
