Elderly people suffering from insomnia may be better advised to seek help from cognitive behavioural therapy than sleeping pills, according to research published by Oxford and Bristol on Monday, 19 January 2004.
The team systematically examined scientific evidence to assess the effectiveness of cognitive behavioural treatments for insomnia for the over 60 year olds. Such treatment aims to improve sleep by changing poor sleeping habits and challenging negative thoughts, attitudes or beliefs a
Today there is a great need for portable equipment that can quickly detect chemical and biological weapons such as nerve gases, viruses, bacteria, and toxins. In a new dissertation the Swedish researcher Inga Gustafsson shows that artificial membranes can be used for this purpose in future biosensors.
Biosensors have already proven to be useful in the detection of impurities in food and water, for example. They have also been used in industrial processes, clinical analyses, and the develop
Discovery, Published in the Proceedings of the National Academy of Sciences, Flies in the Face of Past Assumptions
A UC Riverside team in the Entomology Department has found that genetically engineered mosquitoes are less fertile and less healthy than mosquitoes that have not been altered.
The discovery, made in the laboratory of biological control extension specialist Mark Hoddle, has been included in the latest issue of the journal Proceedings of the National Academy of S
Adult stem cells have long been thought to be restricted in their potential to differentiate and regenerate tissues in which they reside. A study by Sem Phan and colleagues from the University of Michigan, in the January 15 issue of the Journal of Clinical Investigation, suggests that the collagen overproduction and deposition in the lung causing idiopathic pulmonary fibrosis may develop from cells derived from bone marrow stems cells, rather than parenchymal lung fibroblasts.

Different viral strains responding to ideal conditions
Though they may appear as single outbreaks quickly spread by people and wildlife, recent flare-ups of the deadly Ebola virus in Central Africa are actually multiple epidemics of different viral strains, simultaneously appearing when conditions are ideal, according to a study appearing in the journal Science.
The study, authored by the New York-based Wildlife Conservation Society and other groups, said that scientists pr
In a nationwide study of hospitalized patients, researchers at Duke University Medical Center and Brigham and Women’s Hospital found that individuals at risk for developing deep vein thrombosis (DVT) — a disorder characterized by the formation of blood clots in the deep veins of the legs — often fail to receive preventive medications. DVT can cause death when leg clots break free and lodge in the lungs, a condition known as pulmonary embolism.
The study found that, of more than 5,000
About 5 million years ago, the first spiny-legged Tetragnatha spider landed on what is now known as the Hawaiian Islands, with subsequent generations evolving into different species to fill in specific niches in various habitats. Now, these spiders provide evidence for nature’s propensity for generating diversity in a systematic way.
In a new paper published in the Jan. 16 issue of Science, University of California, Berkeley, biologist Rosemary Gillespie uses genetic detective work to descr
The natural world is full of curves and three dimensions, but the ability to deliberately and rationally construct such complex structures using nanoscale building blocks has eluded nanotechnologists who are eager to add curved structures to their toolbox.
Now a team of Northwestern University chemists report they have discovered ways to construct nanoscale building blocks that assemble into flat or curved structures with a high level of predictability, depending on the architecture and com
A clinical trial involving 371 patients in eight countries shows that linezolid, a new antibiotic, is at least as effective as two older therapies for treating diabetic foot infections. The drug may be an important new agent for doctors treating infections that are increasingly caused by bacteria resistant to standard antibiotics, and that in severe cases may require amputation. The study, led by a Department of Veterans Affairs (VA) physician and conducted at 30 U.S. and 15 European sites, appears i
Researchers find odorant in human sweat that attracts female mosquitoes
Today, we know a little bit more about one of mankind’s deadliest enemies, the mosquito. Scientists have taken an important step toward understanding the mosquito’s sense of smell, an avenue of research that may lead to better ways to repel the deadly insect.
In a joint effort reported in the Jan. 15 issue of the journal Nature, researchers at Vanderbilt and Yale universities have verified that
The anticipated Mars landing on Jan. 24 of the Opportunity rover will be a bit more challenging than the Spirit’s bounce onto the red planet earlier this month, according to a University at Buffalo geologist, but if it’s successful, then scientists will be able to be much bolder about selecting future Mars landing sites.
“If both of these landers survive with airbag technology, then it blows the doors wide open for future Mars landing sites with far more interesting terrain,” said
An innovative method that allows increased success and speed of protein crystallization – a crucial step in the laborious, often unsuccessful process to determine the 3-dimensional structure unique to each of the body’s tens of thousands of folded proteins – has been developed by researchers at the University of California, San Diego (UCSD) School of Medicine and verified in tests with the Joint Center for Structural Genomics (JCSG) at The Scripps Research Institute (TSRI) and the Genomics Institute
A 7-month-old child whose first corneal transplant was unsuccessful underwent surgery Monday at the University of Rochester Eye Institute to implant an artificial cornea in an effort to give him sight. He is the youngest patient ever to receive the device.
Lukas Rakowsky of Dupont, Wash., was born in May with a tumor on his left eye. The tumor was successfully removed five weeks after his birth at Madigan Army Medical Center in Ft. Lewis, Wash. Lukas also underwent corneal transplant surger
A new study has found that cereal fortified with vitamin E has a very high rate of absorption into the bloodstream, whereas pills taken separately with the same food have inconsistent effects, and taking the supplements alone is largely useless.
The research was just published in the American Journal of Clinical Nutrition by scientists from the Linus Pauling Institute at Oregon State University.
The study points the way to more effective methods of taking this essential vitamin if p
Massive Siberian peat bogs, widely known as the permanently frozen home of untold kilometers of moss and uncountable hordes of mosquitoes, also are huge repositories for gases that are thought to play an important role in the Earth’s climate balance, according to newly published research by a team of U.S. and Russian scientists in the Jan. 16 edition of the journal Science.
Those gases, carbon dioxide and methane, are known to trap heat in the Earth’s atmosphere, but the enormous
The first prototype of personalised UMTS Services was tested on the TU Delft campus. A number of congress visitors and a group of students were able to use UMTS and GPS to find their way to a lecture or restaurant, contact other visitors, get a tour of the campus, play a game together or watch a movie clip on internet. Both groups reacted enthusiastically.
UMTS will be introduced in the Netherlands this year. UMTS makes fast and wireless transmissions of large amounts of digital information
