• The malaria mosquito is disappearing – researchers wonder why

    The incidence of malaria in many African countries south of the Sahara is falling rapidly; a research group has discovered that the mosquito carrying the malaria parasite has practically disappeared from villages without organized mosquito control; there are several hypotheses about the cause of the decline, but without proper data researchers cannot say whether malaria is being eradicated or whether it is just resting up before returning with renewed vigor

  • Common bacterium stops mosquitoes from transmitting Dengue virus

    Strains of a bacterium commonly found in fruit flies can prevent the Aedes aegypti mosquito from transmitting the virus that causes dengue fever, researchers have found; the discovery could lead to a more effective way to control dengue worldwide

  • Overcoming dangerous antibiotic-resistant bacteria

    Scientists have successfully reengineered an important antibiotic to kill the deadliest antibiotic-resistant bacteria; the compound could one day be used clinically to treat patients with life-threatening and highly resistant bacterial infections

  • Coriander oil tackles food poisoning and drug-resistant infections

    Coriander oil has been shown to be toxic to a broad range of harmful bacteria; its use in foods and in clinical agents could prevent food-borne illnesses and even treat antibiotic-resistant infections, according to the authors of a study published in the Journal of Medical Microbiology

  • Source of Haitian cholera outbreak identified

    Employing technology that reads the entire DNA code, researchers have pinpointed the source of a cholera outbreak in Haiti that killed more than 6,000 people and sickened 300,000; the researchers also suggest how to prevent future outbreaks when international aid is rushed to disaster areas

  • Tap water in Copenhagen contaminated with E.coli

    Parts of the Danish capital Copenhagen were without clean drinking water Saturday after high levels of the E.coli bacteria were detected in the municipal tap water system

  • Cleaning water while generating energy

    A fuel cell system that can generate electricity from organic compounds and clean up wastewater at the same time has been developed by scientists in China; the cell uses light energy to degrade organic compounds in wastewater, generating electrons that pass through to the cathode, which converts the chemical energy into electrical energy

  • Radiation fears cripple Japanese food exports

    Japanese agricultural exports have yet to recover from the 11 March earthquake and tsunami due largely to fears of radioactive contamination; to combat these fears, local governments have done all they can to assure consumers that their products are safe; consumers remain wary despite these reassurances, and as a result the Japanese agricultural sector is struggling

  • How did H1N1 become an pandemic?

    The last century has seen two major pandemics caused by the H1N1 virus — the Spanish Flu in 1918 and 2009’s Swine Flu scare, which had thousands travelling with surgical masks and clamoring for vaccination; scientists, however, did not know what distinguished the Swine Flu from ordinary influenza in pigs or seasonal outbreaks in humans, giving it the power to travel extensively and infect large populations; until now

  • Software successfully predicted spread of West Nile virus in California

    A computer model of the spread of West Nile virus was able to predict areas where human cases would be concentrated, especially around Sacramento in 2005; the success of the model, say researchers, depended on its focus on biological factors and on a high volume of reports from members of the public

  • Anthrax exposure prompts FBI investigation

    Government health officials are currently investigating a case of anthrax exposure in Minnesota after tests confirmed that an individual hospitalized there had been infected with the dangerous bacteria; due to the deadly nature of anthrax and its use as a biological weapon, the FBI joined Minnesota health officials in investigating the matter

  • Medical silver bullet: New drug cures most viral infections

    Researchers at MIT’s Lincoln Lab have developed technology that may someday cure the common cold, influenza, and other ailments; the researchers tested their drug against fifteen viruses, and found it was effective against all of them — including rhinoviruses that cause the common cold, H1N1 influenza, a stomach virus, a polio virus, dengue fever, and several other types of hemorrhagic fever

  • Reversing metabolism to make biofuels at breakneck pace

    Engineers reverse E. coli metabolism for speedy production of fuels, chemicals; a Rice University’s team reversed one of the most efficient of all metabolic pathways — the beta oxidation cycle — to engineer bacteria that produce biofuel at a breakneck pace

  • A natural food preservative kills food-borne bacteria

    Salmonella and E. coli account for more than half of all food recalls in the United States; salmonella contributes to an estimated 28 percent of more than 3,000 U.S. deaths related to foodborne illness each year; researchers have discovered and received a patent for a naturally occurring lantibiotic — a peptide produced by a harmless bacteria — that could be added to food to kill harmful bacteria like salmonella, E. coli, and listeria

  • Innovative biosensor for rapid virus field tests

    Relying on a novel DNA-based bio-chemo-physical conversion method, a new bio-detection device is able to detect harmful bacteria, such as E. coli, salmonella, and staphylococcus, on site, within thirty minutes; it can be adapted to cover such deadly viruses as SARS, H5N1 flu, and swine flu viruses; it can also be designed to monitor possible biological attack from anthrax, smallpox, cholera, and more
