Ancient olfaction protein is shared by many bugs, offering new pest control target

In the battle against insect pests, new research indicates that it may all come down to the sense of smell. A group of Rockefeller University scientists who had previously identified a key gene essential for the sense of smell in fruit flies now shows that this gene's function appears to be evolutionarily conserved across very different insect species. Research by Leslie Vosshall's laborat...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

Call it a chemical crystal ball. A new approach to predict whether a drug in development is likely to work and which dose is best could get antibiotics to market faster and more cheaply, say University of Florida researchers. In recent years, scientists worldwide have sounded the alarm: There simply aren’t enough drugs to combat bad bugs. Bacteria are increasingly adept at outwitting the t...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

We have much to learn from bad bugs, according to Gilbert Waldbauer, whose book "Insights From Insects: What Bad Bugs Can Teach Us" was published March 1 (Prometheus Books). "We know a lot about pests, because so much money is spent on their research," said Waldbauer, professor emeritus of entomology at the University of Illinois at Urbana-Champaign. Of the 900,000 known species of insect...

Scientists find viruses can't stick to sea bugs in the dark

Blue-green algae, or cyanobacteria, in the seas are as vital to the survival of life on earth as the oxygen producing plants are on land. But marine bacteria are attacked by viruses, which can seriously affect their life-sustaining abilities but mow a researcher at the University of Warwick has discovered that these viruses don't work in the dark, according to research presented today (Monday, 04...

Two studies document rise of superbugs in the environment

As science gets wiser, so do the bugs. The rates of drug-resistant bacteria infecting patients in the community and in the hospital have been increasing steadily in recent years, according to two new studies in the June 15 issue of Clinical Infectious Diseases, now available online. Drug resistance in microorganisms has become a problem due in part to inappropriate prescribing and overuse...

Got bugs? New project lets real computer users gang up on software bugs

Ben Liblit offers a bold prediction regarding all of the complicated software programs churning away in your computer: They have bugs. All of them. Guaranteed. "Software bugs are part of the mathematical fabric of the universe," says Liblit, a University of Wisconsin-Madison computer scientist. "It is impossible with a capital 'I' to detect or anticipate all bugs." <div...

Machines take over the battle against hospital bugs

Hospital acquired infection is one of the most common reason which results in fatal complications among hospital patients. One of the most common and potentially dangerous bug which causes this type of infection is the bacterium// called acinetobacter. This bacterium is found naturally in the environment and survives drying and thrives in dust and on inanimate surfaces for long periods....

Use of antibiotics in farms may increase ‘super bugs

A new research has pointed out the increasing problem of super bugs to the extensive// use of antibiotics in the agricultural farmlands. Super bugs are a new kind of microorganisms, mainly bacteria by nature, which may not be affected by a wide range of antibiotics. The researchers of Fogarty International Center and others who together had published the research report blam...

Super Bugs Contaminate UK Chickens

More than half of the chickens sold in UK shops were contaminated with Super bugs. The study shows that immediate attention is to given to reduce the indiscriminate use of antibiotics in animals and to // protect the spread of antibiotic resistant bacteria from farms into people. Super bugs are multiple drug resistant bacteria. British grown chickens analyzed were found to be contaminat...

Atypical Antibiotics For Super Bugs

Researchers from the Notre Dame University have developed unusual antibiotics that have the potential to be effective against the super bugs. The research findings were presented at the 230th national meeting of the American Chemical Society, the world’s largest scientific society. // The new antibiotics are synthetic forms of cephalosporin, a broad-spectrum antibiotic closely related...

Self-defense Mechanism of food borne bugs found

Professor Ray Dixon and his research team from Georgia Institute of Technology, US and the John Innes Center, UK have found a mechanism by which the pathogenic bacteria defends itself from the defense mechanism of the host. //The researchers have reported the results of their research in the Journal Nature. Pathogenic bacteria cause food borne illness by producing toxins in the food...
