  • Bacterioplankton: Taking their vitamins
    on October 17, 2018 at 4:44 pm

    New research finds that more bacterioplankton utilize vitamin B1 or B1 precursors from their environment than synthesize their own. The researchers also found that B1 availability can directly limit bacterioplankton growth, which could have larger impacts on aquatic microbial food webs, as well as energy and nutrient exchange. […]

  • Plant hormone makes space farming a possibility
    on October 17, 2018 at 1:49 pm

    With scarce nutrients and weak gravity, growing potatoes on the Moon or on other planets seems unimaginable. But the plant hormone strigolactone could make it possible, plant biologists have shown. The hormone supports the symbiosis between fungi and plant roots, thus encouraging plants' growth -- even under the challenging conditions found in space. […]

  • Infectious diarrhea spores survive high temperatures of hospital laundering
    on October 16, 2018 at 3:01 pm

    Washing contaminated hospital bedsheets in a commercial washing machine with industrial detergent at high disinfecting temperatures failed to remove all traces of Clostridium difficile (C. difficile), a bacteria that causes infectious diarrhea, suggesting that linens could be a source of infection among patients and even other hospitals, according to a new study. […]

  • Dual vaccine against anthrax and plague
    on October 16, 2018 at 12:13 pm

    A team of researchers has now engineered a virus nanoparticle vaccine against Bacillus anthracis and Yersinia pestis, tier 1 agents that pose serious threats to national security of the United States. B. anthracis and Y. pestis are the pathogens that cause anthrax and plague, respectively. Using bacteriophage T4, the scientists developed the vaccine by incorporating key antigens of both B. anthracis and Y. pestis into one formulation. Two doses of this vaccine provided complete protection against both inhalational anthrax and pneumonic plague in animal models. […]

  • How beetle larvae thrive on carrion
    on October 15, 2018 at 7:06 pm

    The burying beetle Nicrophorus vespilloides buries the cadavers of small animals to use them as a food source for its offspring. However, the carcass is susceptible to microbial decomposition. Researchers show that the beetles replace harmful microorganisms with their own beneficial gut symbionts, thus turning a carcass into a nursery with a microbial community that even promotes larval growth. […]

  • Virus-resistant pigs to vastly improve global animal health
    on October 15, 2018 at 5:29 pm

    Researchers have successfully produced a litter of pigs that are genetically resistant to Transmissible Gastroenteritis Virus (TGEV), which commonly infects the intestines of pigs and causes almost 100 percent mortality in young pigs. […]

  • Unravelling the genetics of fungal fratricide
    on October 15, 2018 at 3:35 pm

    Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings. Unexpectedly, the genes were not related to each other, perhaps indicating that selfish genes are more common than previously thought. […]

    on October 15, 2018 at 2:04 pm

    Researchers developed a system that can automatically image single molecules within living cells. This system employs learning via neural networks to focus appropriately on samples, search automatically for cells, image fluorescently labeled single molecules, and track their movements. With this system, the team achieved the automated determination of pharmacological parameters and quantitative characterization of the effects of ligands and inhibitors on a target, which has potentially profound implications for biological and medical sciences.

  • Goldilocks principle in biology: Fine-tuning the 'just right' signal load
    on October 12, 2018 at 3:01 pm

    In 'Goldilock and the Three Bears', Goldilock finds that only one bowl of porridge has the ''just right'' temperature, and in the same way within biology, you can find the 'just right' conditions -- called the Goldilocks principle. This a research team has done by demonstrating that in order to get the 'just right' amount of signalling for symbiosis in the roots of legumes, a specific enzyme called chitinase (CHIT5) must be present. […]

  • Irrigating vegetables with wastewater in African cities may spread disease
    on October 12, 2018 at 2:22 pm

    Urban farmers growing vegetables to feed millions of people in Africa's ever-growing cities could unwittingly be helping to spread disease by irrigating crops with wastewater, a new study reveals. […]

  • Understanding the neurological code behind how flies fly
    on October 12, 2018 at 12:27 pm

  • Photoactive bacteria bait may help in fight against MRSA infections
    on October 11, 2018 at 9:31 pm

    Researchers are testing whether a light-active version of heme, the molecule responsible for transporting oxygen in blood circulation, may help people infected with MRSA. Photodynamic therapy, or PDT, involves a compound known as a photosensitizer, which can be activated by visible light to kill diseased cells or bacteria. PDT is a clinically proven method for fighting cancer but has not yet been developed for treating MRSA infections. […]

  • New route of acquiring antibiotic resistance in bacteria is the most potent one to date
    on October 11, 2018 at 6:31 pm

    For the first time in 60 years, researchers have discovered a new mechanism of genetic transduction, the process by which bacteriophages transfer bacterial DNA between bacteria. This new mechanism (lateral transduction) is the most powerful to date, able to transfer large DNA stretches at high frequencies. It likely plays a major role in bacterial evolution and acquisition of antibiotic resistance. […]

  • Clues from a Somalian cavefish about modern mammals' dark past
    on October 11, 2018 at 3:24 pm

    After millions of years living in darkness, a species of blind cavefish has lost an ancient system of DNA repair. That DNA repair system, found in organisms including bacteria, fungi, plants, and most other animals, harnesses energy from visible light to repair DNA damage induced by ultraviolet (UV) light. The findings are intriguing in part because only placental mammals were previously known to lack this system. […]
