Ennore Port oil spill spreads all along Chennai's shoreline up to Marina

       The oil spill supposedly from two ships that collided near the Ennore Port, north of Chennai, on Saturday, spread along the city's shoreline further down up to the famed Marina Beach. On Monday morning, the local fishermen and the morning walkers were shocked to find not just thick black oil along the beach, but a number of turtles that were washed ashore dead.

Drought identified as key to severity of West Nile virus epidemics

       A study led by UC Santa Cruz researchers has found that drought dramatically increases the severity of West Nile virus epidemics in the United States, although populations affected by large outbreaks acquire immunity that limits the size of subsequent epidemics.

Superbug death spurs drug regulator warning

       The Drugs Controller General of India (DCGI) has also asked companies to carry specified warnings to avoid antimicrobial resistance. “To contain anti-microbial resistance, the office has been advising the supply chain system in India to follow strict requirements of Schedule H and H1 for sale of medicines,“ DCGI G N Singh said in a notice issued to all state regulators and other stakeholders.

Bacterial explorers move fast

       Streptomyces bacteria are common in soil and generate many antibiotics. Marie Elliot at McMaster University in Hamilton, Canada, and her colleagues cultured Streptomyces venezuelae along with baker's yeast (Saccharomyces cerevisiae) for 14 days. They found that the bacteria form non-branched filaments that spread over various surfaces (pictured) and obstacles. The 'explorer' cells released a volatile alkaline compound that stimulated physically separated Streptomyces to initiate exploration, and inhibited the growth of other bacteria. This exploratory growth could be a way for the organisms to scavenge more nutrients, the authors say.

Strep spreads by harnessing immune defenses of those infected

       Streptococcus pneumonia spreads by harnessing immune defenses of those infected. The bacteria that cause most cases of pneumonia worldwide secrete a toxin that helps them jump from one body to the next - with help from the hosts' immune defenses. This is the finding of a study led by researchers from NYU Langone Medical Center and published online January 11 in Cell Host & Microbe.

Bacterial protein structure could aid development of new antibiotics

       Researchers at Duke University solved the structure of an enzyme that is crucial for helping bacteria build their cell walls. The molecule, called MurJ (shown in green), must flip cell wall precursors (purple) across the bacteria's cell membrane before these molecules can be linked together to form the cell wall. This new structure could be important to help develop new broad-spectrum antibiotics. Credit: Alvin Kuk, Duke University.

Researchers discover 'marvel microbes' explaining how cells became complex

       In a new study, published in Nature this week, an international research group led from Uppsala University in Sweden presents the discovery of a group of microbes that provide new insights as to how complex cellular life emerged. The study provides new details of how, billions of years ago, complex cell types that comprise plants, fungi, but also animals and humans, gradually evolved from simpler microbial ancestors.

Worms have teenage ambivalence, too

       Salk Institute scientists studying roundworms suggest that, in both worms and humans, adolescent brains mature to stable adult brains by changing which brain cells they use to generate behavior. Teen worm brains drive wishy-washy behavior that allows them to stay flexible in an uncertain world, while adult worm brains drive efficient behavior. The discovery provides insight into the underlying drivers of neurological development that could help better understand the human brain and disease.

Salmonella bacteria threatens Mudumalai

       Chikku, a cattle herder in Gudalur in the Nilgiris, is a worried man. “Water in the Dhodda Moyar was a little dark last week. When my cattle drank it, they fell sick and in the next couple of days more than half a dozen of them died,“ he says. Siva, a worker in a farm in the same area, said he went to bathe in the river, but changed his mind since the water was dark in colour. Subsequently two cattle from the farm where he works died.
