In the next 60 seconds, another child will be on his/her way to the hospital to be treated for serious burns; it happens more than 300 times a day in this country.* Now, one of the largest studies ever done on burn injuries in kids is out from experts at Nationwide Children's Hospital and the results are mixed: while overall injuries are down, there are some kids who are still at serious risk.<
DURHAM, N.C. -- As scientists work toward making genetically altered bacteria create living "circuits" to produce a myriad of useful proteins and chemicals, they have logically assumed that the single-celled organisms would always respond to an external command in the same way.
Alas, some bacteria apparently have an individualistic streak that makes them zig when the others zag.
New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture.
DURHAM, N.C. -- The link between obesity and osteoarthritis may be more than just the wear and tear on the skeleton caused by added weight.
A Duke University study has found that the absence of the appetite hormone leptin can determine whether obese mice experience arthritis, no matter how heavy they are.
UCLA scientists have identified two chemicals that convince cells to ignore premature signals to stop producing important proteins. Published in the Sept. 28 edition of the Journal of Experimental Medicine, the findings could lead to new medications for genetic diseases, such as cancer and muscular dystrophy, that are sparked by missing proteins.
RICHLAND, Wash. -- Catalysts convert useless or unwanted chemicals into useful or more desirable ones. Research in this week's Science reveals new, important details about a common catalyst: how rafts of chemically reactive platinum form in the catalyst.
A comparison of breast milk samples from Denmark and Finland revealed a significant difference in environmental chemicals which have previously been implicated in testicular cancer or in adversely affecting development of the fetal testis in humans and animals. This finding is published today in the International Journal of Andrology.
COLUMBIA, Mo. -- About 2 million Americans currently use cocaine for its temporary side-effects of euphoria, which have contributed to making it one of the most dangerous and addictive drugs in the country. Cocaine addiction, which can cause severe biological and behavioral problems, is very difficult to overcome.
COLUMBUS, Ohio -- Scientists expect a new mathematical model of chronic wound healing could replace intuition with clear guidance on how to test treatment strategies in tackling a major public-health problem.
Rush University Medical Center is participating in a large-scale, multi-center clinical trial in the U.S. and Canada to determine whether a vitamin-like substance, in high doses, can slow the progression of Parkinson's disease, a neurodegenerative disorder that affects about one million people in the United States.
By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale -- and the findings look promising.
Levels of chloride, a component of salt, are elevated in many urban streams and groundwater across the northern U.S., according to a new government study.
So you're a manufacturer about to introduce a new consumer product to the marketplace. Will that product or the manufacture of the product contribute to global warming through the greenhouse effect? Until now, there was no clear way to answer that question.
Individuals whose occupation involves contact with pesticides appear to have an increased risk of having Parkinson's disease, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals.
Before entering the cleanroom, the researcher dons special protective clothing to avoid carrying germs or other impurities into the highly sensitive environment. But it's not only people who have to conform to the strict hygiene requirements. Every item of equipment in the room, from lithography units to swivel chairs, must also comply with international guidelines.
