A new anti-herpes agent derived from a common herb effectively treats and prevents the disease in animals. Researchers from Dalhousie University in Nova Scotia present their data today at the 103rd General Meeting of the American Society for Microbiology.
“Prunella vulgaris [also known as self-heal] is a perennial plant commonly found in China, the British Isles, Europe, and North America. In herbal literature, P. vulgaris has been described as a hot water infusion to treat sores in the mou
Painless bone substitute could offer new era for surgeons
In an operating room in Carle Hospital in Urbana, Ill., on May 7, as scientists from the University of Illinois (UI) and Sandia National Laboratories watched, surgeon Michael Goldwasser fitted a highly unusual ceramic prosthetic device into the mouth of an elderly woman who had lost most of her teeth and along with it, much of the bone of her lower jaw.
The fitting operation was to determine whether the implant – crea
Why do serious diseases such as cancer, Alzheimer’s and Huntington’s mainly hit us in middle age or later? The links between aging and age-related diseases have proved elusive.
In studies of the powerfully informative roundworm, C. elegans, UCSF scientists have discovered that a class of molecules found in the worms and in people can both prolong life in the worm and prevent the harmful accumulation of abnormal proteins that cause a debilitating Huntington’s-like disease. The
The feasibility of using microwaves to extract minerals from rocks has been demonstrated by UK researchers.
This revolutionary technique could cut mining and mineral processing industry costs, and make it viable to process previously uneconomic mineral reserves. It could also help the environment by saving energy as 3 – 5% of the world’s entire electrical energy output is used for the size reduction of rocks and minerals.
The technique has been developed by engineers at the
Dutch chemist Ivan Buijnsters from the University of Nijmegen has successfully produced a diamond layer on a steel substrate. This opens up the possibility of wear-resistant tools. The secret to this technique is an adhesive layer between the steel and the diamond layer.
Buijnsters made diamond layers by allowing methane gas diluted in hydrogen gas to dissociate on a hot wire just above the substrate. The carbon atoms present in the methane dropped onto the substrate and formed a thin layer
The gene for an enzyme that is key to natural disease resistance in plants has been discovered by biologists at the Boyce Thompson Institute for Plant Research (BTI) and at Cornell University. The researchers say that by enhancing the activity of the enzyme they might be able to boost natural disease resistance in crop plants without resorting to pesticides or the introduction of non-plant genes.
The research, reported in the latest (May 16) issue of the journal Cell , describes the discov
