Scientists have discovered the use of a simple single-celled amoeba to understand the function of human proteins in causing Alzheimer’s disease.
The new study, published in the Journal of Cell Science today (Friday 24 January) by researchers at Royal Holloway, University of London and the Ins... Read More
Scientists at Scripps Institution of Oceanography at UC San Diego have developed a new genetic platform that allows efficient production of naturally occurring molecules, and have used it to produce a novel antibiotic compound.
“In my opinion, the new synthetic biology technology we develope... Read More
Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research, which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.
Incidence of alle... Read More
Much like how a snowplow is needed to clear streets of heavy snow, cells employ a set of genes to clear away misfolded proteins, to prevent them from accumulating and destroying the cell.
For the first time, Cornell researchers have demonstrated how a gene called SEL1L plays a critical role i... Read More
Mechanisms that determine the size of plants have fascinated plant scientists of all times, however they are far from understood. An international research team led by plant scientists from VIB and Ghent University report an important breakthrough in the scientific journal The Plant Cell. They i... Read More
Canada has discovered its first two cases of the Porcine Epidemic Diarrhea virus (PEDv), which has already killed more than 1 million pigs in the United States, government and industry officials said on Thursday.
The Ontario government is investigating a hog farm in the province's Middlesex C... Read More
Two people who mattered to me and to many other people have died recently. I wish to honor their memory by sharing a glimpse of them with you.
Manny died on January 8, 2014, one month shy of his 96th birthday. A member of a distinguished Swiss family, he earned his MD in Basel ... Read More
Some may think of turkeys as good for just lunch meat and holiday meals, but bioengineers at UC Berkeley saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathog... Read More
The University of Liverpool is to decipher the genomes of the UK’s main bacterial cause of food poisoning which results in over 21,000 hospital admissions and 100 deaths each year. Using the latest whole genome sequencing technologies available at the University’s Centre for Genomic Research, sc... Read More
We are more than just our genes, and it’s no different for bacteria. Genetically identical bacteria behave in dramatically different ways. This phenomenon has been seen in factors such as growth rate, metabolism and resistance to antibiotics.

Should we only consider bacteria as harmful to our bodies?
Bonnie Bassler is a molecular biologist who has made a stunning discovery: bacteria 'talk' to each other using chemical signals that enable them to act as a unit, mount attacks and coordinate defence. This phenomenon of bacterial com... Read More
A new study from Karolinska Institutet in Sweden finds that testing for human papilloma virus (HPV) allows for longer time between screening tests when compared to cytology-based testing. The study is published in the scientific journal British Medical Journal (BMJ).
Cervical screening progra... Read More
In a move to reduce health care associated infections, certain attire for health care professionals, including the traditional white coat, could become a thing of the past.
"White coats, neckties, and wrist watches can become contaminated and may potentially serve as vehicles to carry germs f... Read More
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it “could do little harm and might provide a touch of home, in addition to a spot of hunting.”
By the end of the century, the rabbits had begun to overrun native ecosystems, reaching ... Read More
New research finds significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system. Contaminated water poses an increased risk for infection in immunocompromised patients. The study was published in the February iss... Read More
Going barefoot in parts of Africa, Asia, and South America contributes to hookworm infections, which afflict an estimated 700 million of the world’s poor. The parasitic worm lives in the soil and enters the body through the feet. By feeding on victims’ blood, the worms cause anemia and, in child... Read More
A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.
The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More
An international team of researchers has made important progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredator... Read More
A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.
Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More
