Study shows nanoshells ideal as chemical nanosensors

'Nanoshells' enhance sensitivity to chemicaldetection by factor of 10 billionNew research published in the Proceedings of the National Academy ofScience finds that tailored nanoparticles known as nanoshells canenhance chemical sensing by as much as 10 billion times. That makesthem about 10,000 times more effective at Raman scattering thantraditional methods. Whenmolecules and materi...

Mutation in clams protects against paralytic shellfish poisoning but raises human health risk

Just like people, clams can be affected by the toxins that cause paralytic shellfish poisoning (PSP), but scientists have now identified a mutation in clams that gives some protection. PSP toxins interfere with nerve function, and the mutation, which changes a single amino acid in a sodium channel, makes nerves less sensitive to those toxins. The discovery is reported in the April 7 issue...

Research Reveals Functions Of Harmful Shellfish Pathogens

Providing safer shellfish is the goal of Agricultural Research Service (ARS) scientists who are studying the means by which pathogenic bacteria enter shellfish. In the United States, two pathogenic bacteria from the genus Vibrio are of concern: V. vulnificus and V. parahaemolyticus. These bacteria are naturally found in shellfish and seawater, particularly when water temperatures are warm,...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

They're but a tiny speck, existing in a variety of forms: particles, tubes, shells, even a soccerball-like shape. They also share a common prefix: "nano," connoting their size, a billionth of a meter or roughly 25-millionth of an inch. Today, cancer researchers are exploring the potential of such nanostructures to exquisitely target cancer cells without harming surrounding tissue, and to...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

Kansas State University researchers think their discovery of the enzyme involved in the hardening of a beetle's exoskeleton or cuticle could lead not only to better pest control, but also help create similar strong, lightweight materials for use in aircraft and armor. After a beetle first molts, its exoskeleton is soft and hydrated. Somehow, it dries out and forms a hard, stiff exoskeleto...

Waiting list in British healthcare causing them to shell out a fortune!

Due to long and endless waiting lists for patients in Britain, they are forced into taking treatment elsewhere and that causes them a fortune //. For example citing an arthritis case of an Ulster man, who had to pay thousands of pounds so that he can be cured fast, could have done free if by NHS. But the waiting list was too long to wait for. He had to spend ￡3,500 on two drugs - Hum...

Warning on Eating Shellfish Stepped Up

Continued reports of illness caused by eating raw shellfish have made the U.S. Food and Drug Administration to issue a warning today against eating raw shellfish. Reports coming// in show that oysters and clams raised in the Pacific Northwest have made people sick across the country. Till date there have been about 200 reported cases of people coming down with gastroenteritis after eating raw s...

Lobster Shells Have Great Healing and Antiseptic Properties

Scientists from the University of Havana have found that two compounds from lobster shells, chitin and chitosan, have healing and bio-stimulant properties. The researchers said that the compounds could be used to create surgical materials with great healing and antiseptic properties, as well as to increase growth speed and germination in seeds. Chitin is a very common...
