Nanoscale switch could serve as sensor, medical tool

Improving significantly on an early prototype, Johns Hopkins University researchers have found a new way to join two unrelated proteins to create a molecular switch, a nanoscale "device" in which one biochemical partner controls the activity of the other.

Study finds that stomach cancer originates from bone marrow derived stem cells, rather than from stomach stem cells

A common assumption among cancer specialists is that most cancers originate from tissue stem cells – for example, the gastric stem cells contained in the lining of the stomach.

Acid-resistant bug also alcohol-resistant

A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that "just says no to acid."

Cells linked to asthma and eczema also help cure deadly illness in mice

Mast cells are immune cells known mostly for their unwanted effects: they cause the wheezing of asthma, the itching of eczema, the sneezing and runny nose of hay fever and, in extreme cases, the life-threatening shock of anaphylaxis.

Research advances understanding of urinary tract infections

Anyone who has ever had a urinary tract infection knows that they can be difficult to fight.

Carbon coatings to prevent bacteria collecting on indwelling catheters

This team of physicists have coated catheters and ureter stents with an extremely thin layer of diamond-like carbon. DLC-coated surfaces do not react chemically with their environment; they are hardwearing, can be sterilised and reduce friction.

Eating apples may protect against Alzheimer's and Parkinsonism

A group of chemicals in apples could protect the brain from the type of damage that triggers such neurodegenerative diseases as Alzheimer's and Parkinsonism, according to two new studies from Cornell University food scientists.

Research shows that even bacteria don't put their eggs in one basket

Diversification helps reduce overall risk by putting your eggs in more than one basket and is a strategy that strengthens groups of all kinds -- from forests challenged with environmental stress to stock market portfolios in uncertain times. Findings from University of Iowa researchers show that even bacteria have learned this important lesson.

Discovery of new compounds that may treat mucus build-up associated with cystic fibrosis

Preliminary studies show these compounds improve the flow of mucus through the respiratory tract, allowing airways to clear more quickly and efficiently.

Research opens up new avenues to diagnosis and treat Lyme disease

Researchers at Yale School of Medicine have identified a Lyme disease receptor called TROSPA that is used by disease agents to invade ticks.

Vaccine provides new hope to the millions of people who suffer from food allergies

A team led by a researcher at the Stanford University School of Medicine has developed vaccines that vastly reduce or eliminate dogs' allergic reactions to three major food allergens: peanuts, milk and wheat. The vaccines' benefits lasted at least three months.

Important advance in understanding the structure of phage viruses

An important advance in understanding the structure of phage viruses, which infect and destroy bacteria, has been made by a team of scientists from Oxford and Finland, which could help develop new strategies to combat bacterial infections.

Nanogen announces clinical diagnostic to simultaneously detect multiple respiratory viruses

Nanogen announced today that it is developing new analyte specific reagents (ASRs) for clinical reference laboratories to develop and validate a single test to detect six of the most common respiratory viruses.

Cranberry juice may help prevent gum disease

New research presented at a recent symposium suggests that cranberry juice may help prevent certain oral health problems, including diseases of the gums and teeth.

Researchers attempt to quantify processes underlying cell heterogeneity

Combining the latest methods in gene splicing and computer modeling, Rice University researchers are trying to develop a predictive framework for one of the most basic and complex biological phenomena — cellular heterogeneity, or the ability of genetic clones to act and behave differently when exposed to the same set of environmental stimuli.

Infection rates from MRSA superbug will be halved by 2008, according to Health Secretary John Reid

Blood borne infection rates of the hospital superbug MRSA will be halved by 2008, Health Secretary John Reid said in a speech last week.

Tiny, vibrating paddle oscillator senses the mass of a virus

By using a device only six-millionths of a meter long, researchers at Cornell University have been able to detect the presence of as few as a half-dozen viruses -- and they believe the device is sensitive enough to notice just one.

Turf burns and body shaving responsible for the spread of a bacterial skin infection among football players

Turf burns and cosmetic body shaving were responsible for the spread of a bacterial skin infection among players on a college football team, according to an article in the November 15 issue of Clinical Infectious Diseases, now available online.

Autophagy may even provide a clue to the mythical fountain of youth

The cells of higher organisms have an internal mechanism for chewing up and recycling parts of themselves, particularly in times of stress, like starvation and disease. But nobody is quite sure yet whether this recently discovered process protects cells, or causes damage.
