NewsThe link between the gut microbiome and autism is not backed by science, researchers say
There’s no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper. They warn that conclusions that supported this hypothesis are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.

NewsAvian flu halves South Georgia’s breeding elephant seal population
South Georgia’s breeding population of female southern elephant seals (Mirounga leonina) may have been halved by highly pathogenic avian influenza virus (HPAIV), finds new research. These losses may threaten the security of the island’s breeding population.

NewsManganese is Lyme disease bacterium’s double-edged sword
For decades, Lyme disease has frustrated both physicians and patients alike. Caused by the corkscrew-shaped bacterium Borrelia burgdorferi, the infection, if left untreated, can linger for months, leading to fever, fatigue and painful inflammation. Source: U.S. Centers for Disease Control and Prevention This digitally colorized scanning electron microscopic ...

NewsImaging reveals bacterial symbionts in the ovaries of tiny, aquatic crustaceans
Researchers have imaged a heritable form of bacterial symbiosis inside the reproductive system of tiny crustaceans known as ostracods. Bacteria from the genus Cardinium live inside the egg cells and tissues of ostracod ovaries, transmitted from mothers to offspring.

NewsScientists find way to find the gut microbiome into a longevity factory
A team of researchers has found a way to turn the bacteria living in the digestive tracts of animals into factories that can produce compounds that promote longevity in their hosts—showing a potential new drug development strategy.

NewsRainfall and temperature shape mosquito fauna in Atlantic Forest bromeliads, including malaria vectors
Results from a study of mosquito larvae conducted in a natural area in the municipality of São Paulo (Brazil) may help estimate the effects of climate change on disease transmission risk in the biome.

NewsHigher methane emissions from warmer lakes and reservoirs may exacerbate worst-case climate scenario
Emissions of the greenhouse gas methane from lakes and reservoirs risk doubling by the end of the century due to climate change according to a new study. This in turn could raise Earth’s temperature more than suggested by the UN climate panel IPCC’s current worst-case scenario.

NewsBacteriophage characterization provides platform for rational design
Researchers have described the bacteriophage Bas63 in unprecedented detail, supporting new mechanistic understanding of how these viruses function.

NewsScientists tie lupus to a virus nearly all of us carry
The Epstein-Barr virus is directly responsible for commandeering what starts out as a minuscule number of immune cells to go rogue and persuade far more of their fellow immune cells to launch a widespread assault on the body’s tissues, a study has shown.

NewsStudy finds high rates of antibiotic-resistant bacteria in raw milk
Raw cow and sheep milk is frequently contaminated with antibiotic-resistant bacteria that could pose a threat to human and animal health, reports a new study.

NewsSingle-dose malaria treatment combining four existing drugs as effective as more onerous multi-day, multi-dose regimen
Hundreds of malaria patients participating in a clinical trial in Gabon in West Africa were cured via a single dose of a treatment that utilizes four widely available malaria drugs, according to a new study.

NewsAdvanced imaging reveals new fungus species in 407-million-year-old plant fossil from Scotland
Researchers have identified a new species of ancient symbiotic fungus preserved within a 407-million-year-old plant fossil from Scotland. The discovery provides unprecedented three-dimensional insight into one of the earliest known plant–fungus partnerships.

NewsTiny diatoms, big climate impact: How microscopic skeletons rapidly shape ocean chemistry
Researchers have found that diatoms’ intricate, silica-based skeletons transform into clay minerals in as little as 40 days. Until the 1990s, scientists believed that this enigmatic process took hundreds to thousands of years.

NewsDestroying crazy ant nest structure makes them vulnerable to pathogens
Scientists have devised a reliable way to introduce a natural pathogen in colonies, so that invasive tawny crazy ant populations collapse and other native species can recover.

NewsStudy reveals that flu vaccine performance varies by age
New research comparing four different flu vaccines found that the ability of the vaccines to activate cells of the immune system that help to protect against infection varied greatly depending on the vaccine type and age of the patient.

NewsMissing links for rabies in Peru highlights global threats of health inequity
Researchers found that efforts to track dog-related rabies in poorer areas of Peru’s second largest city were lacking even though more dogs were found to have the disease there than in wealthier neighborhoods.

NewsWild grass offers new genetic clues to combat deadliest pathogen of wheat
A new study has identified Aegilops cylindrica, a wild grass closely related to wheat, as a powerful genetic reservoir for resistance against the devastating fungal pathogen Zymoseptoria tritici—the cause of Septoria tritici blotch (STB).

NewsHuman PARP gene could be novel target for viral diseases or immune-mediated disorders
Researchershave discovered a human gene, the protein PARP14, plays a role in regulating interferon, part of the body’s innate immune system. Their study could guide development of antiviral therapies for several groups of viral infection.
