Some bottles of wine are worth thousands of dollars. But if oxygen has leaked past the cork, it could be thousand-dollar vinegar — and theres no way to tell without opening the bottle. Now chemists at the University of California, Davis, can check an unopened bottle for spoilage using nuclear magnetic resonance (NMR), the same technology used for medical MRI scans.
Natural bacteria in wine use oxygen from the air to turn alcohol into vinegar, or acetic acid. If a wine bottle is secur
Children raised in a house with two or more dogs or cats during the first year of life may be less likely to develop allergic diseases as compared with children raised without pets, according to a study in the August 28 issue of the Journal of the American Medical Association. The study was supported by the National Institute of Allergy and Infectious Diseases (NIAID) and the National Institute of Environmental Health Sciences (NIEHS).
“The striking finding here is that high pet exposure ear
Rogue trees are being ‘fingered’ by gene detectives using a well-known technique to catch criminals.
Newcastle University scientists are using DNA fingerprinting to help insurers identify trees that are causing houses to subside.
Often disputes can last for several years, as when two trees of the same kind grow in an area it is very difficult to find out which one is behind the problem. This is because their roots – which can grow underneath a house and cause the subsidenc
Citric acid may help alleviate chronic shortages of critical clotting factor
The common additive that gives “tartness” to orange juice, lemon juice and sodas also can dramatically boost the production of a protein critical for treating victims of hemophilia and other bleeding disorders, a UC Irvine study has found.
The findings indicate that citric acid, the juice additive, may help alleviate recurring shortages of a protein called Factor VIII, which is important for the norm
Results of three studies presented today at the International Congress of The Transplantation Society provide encouraging evidence that a patients immune system can be fooled into accepting a transplanted organ without the need for anti-rejection drugs.
According to one study conducted in India, patients are off the immunosuppressive drug cyclosporine three months after undergoing living donor kidney transplantation and an elaborate set of treatments that included a separate surgical
Analyses of the similar bones to the fossils lead a leading physiologist to term the anthropological finding as farfetched speculation
The remains included a jawbone with teeth, hand bones and foot bones, fragments of arms, and a piece of collarbone. The remains also included a single toe bone; its form providing strong evidence that the pre-human creatures walked upright.
The discovery by two Ethiopian scholars, Yohannes Haile-Selassie, an anthropologist studyin
