An outbreak of whooping cough in California could be the worst in 50 years, the state's Department of Public Health said last week.
The disease, caused by the bacterium Bordetella pertussis, is spread via coughing or sneezing and is highly contagious. On average, one infected person can sprea... Read More
Scientists at the University of East Anglia, have shown that fungus-farming ants are using multiple antibiotics as weed killers to maintain their fungus gardens.
Research led by Dr Matt Hutchings and published in the journal BMC Biology shows that ants use the antibiotics to inhibit the growt... Read More
Syracuse University’s Radhakrishna Sureshkumar, professor and chair of biomedical and chemical engineering in the L.C. Smith College of Engineering and Computer Science, and SU chemical engineering Ph.D. student Satvik Wani have discovered a method to make algae grow faster by manipulating light... Read More
Pathogens make themselves feel at home in the human body, invading cells and living off the plentiful amenities on offer. However, researchers at the Max Planck Institute for Infection Biology, Berlin, together with colleagues at Harvard University, reveal an opposite strategy used to ensure inf... Read More
Engineers believe a new strain of yeast with increased alcohol tolerance is the first step toward more efficient and economical production of biofuels.
Biofuels are produced through microbial fermentation of biomass crops, which yield the alcohol-based fuels ethanol and iso-butanol if yeast i... Read More
Family doctors could instantly detect a raft of diseases – from breast cancer to MRSA – using a cheap hand-held device being developed by the UK-based R&D company Cambridge Consultants.
The CliniHub, now in its early stages of development in partnership with XenBio Fluidics of San Diego, Cali... Read More
When the first positive results of a research trial for an antiretroviral-based vaginal microbicide gel were announced at the International AIDS Conference in Vienna this July, it marked a significant thinning of the line between HIV treatment and prevention. The same agents that had been design... Read More
Crohn's is a condition that affects one in 800 people in the UK and causes chronic intestinal inflammation, leading to pain, bleeding and diarrhoea. Researchers are working with biotechnology company, Provexis, to test a new plantain based food product that could treat patients with the disease.... Read More
For immune compromised individuals, like those living with AIDS, cancer, and burn wounds, and for cystic fibrosis patients, Pseudomonas aeruginosa can cause serious or even fatal infections. Why is it so devastating? One of the essential elements of P. aeruginosa’s virulence is a slick coating... Read More
A new study suggests mother nature might be cleaning up the BP spill faster than expected. Researchers found several species of oil-eating bacteria thriving in the submerged plume, but uncertainty remains over the threat to marine life. The guests will include Ron Atlas, past president of the Am... Read More

Scientists and engineers seek to meet three goals in the production of biofuels from non-edible sources such as microalgae: efficiency, economical production and ecological sustainability. Syracuse University's Radhakrishna Sureshkumar, professor and chair of biomedical and chemical engineering ... Read More
The 2011 ASM Biodefense Meeting (http://www.asmbiodefense.org/) at the Omni Shoreham Hotel in Washington, DC, on Feb 6-9, 2011, will focus on basic and applied research, policy issues, and education related to biodefense and emerging infectious diseases.
Meeting participants represent a blend... Read More
The Gulf of Mexico oil spill has revealed a previously unknown type of oil-eating bacteria, which is suddenly flourishing.
Scientists discovered the new microbe while studying the underwater dispersion of millions of gallons of oil spilled into the Gulf following the explosion of BP's Deepwat... Read More
More than two and a half billion years ago, Earth differed greatly from our modern environment, specifically in respect to the composition of gases in the atmosphere and the nature of the life forms inhabiting its surface. While today's atmosphere consists of about 21 percent oxygen, the ancient... Read More
In the aftermath of the explosion of BP's Deepwater Horizon drilling rig in the Gulf of Mexico, a dispersed oil plume was formed at a depth between 3,600 and 4,000 feet and extending some 10 miles out from the wellhead. An intensive study by scientists with the Lawrence Berkeley National Laborat... Read More
Searching for novel viruses in environmental samples is a lot like searching for a needle in a haystack, but harder. Researchers are usually forced to extract genetic material from a sample, then sequence and align those genes against a database of known sequences, but aligning genes is difficu... Read More
Two preclinical studies which evaluated AVI-7100 against a fully virulent pandemic H1N1 (swine flu) virus had promising results, says AVI Biopharma Inc. Data from the studies revealed statistically significant reductions in average viral titer vs. a saline control (placebo) and a Tamiflu control... Read More
Arizona State University researchers have demonstrated a way to simplify testing patients for infectious diseases and unhealthy protein levels.
New testing instrumentation developed by Antonia Garcia and John Schneider promises to make the procedure less costly and produce results in less tim... Read More
Low-cost vaccines that may have helped prevent the kind of salmonella outbreak that has led to the recall of more than a half-billion eggs haven't been given to half of the nation's egg-laying hens.
The vaccines aren't required in the U.S., although in Great Britain, officials say vaccinatio... Read More
