NewsBizarre new fossils shed light on ancient plankton
A scientist from the University of Leicester has discovered a new type of fossil that reveals life in the oceans half a billion years ago.

NewsSingle model predicts trends in employment, microbiomes and forests
Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests.

NewsZika infection in pregnant macaques slows fetal growth
Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study.

NewsSunflower extract fights fungi to keep blueberries fresh
Rresearchers have reported that compounds from sunflower crop waste prevent rotting in blueberries. They suggest the food industry could use these natural compounds to protect against postharvest diseases.

NewsBiological fingerprints in soil point the way to diamond-containing ore
Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil.

NewsScientists uncover cause of mysterious deaths of elephants in Zimbabwe
A bacterium, closely associated with deadly septicaemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighbouring countries. The findings place infectious diseases on the list of pressures on African elephants, whose populations continue to be under threat. During this ...

NewsMicrobiome of fruit and vegetables positively influences diversity in the gut
In a meta-study, a research team has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut.

NewsReduced activity of key enzyme linked to microcephaly in Zika-infected offspring
Researchers have shown that brain activity of Ndel1, an enzyme that plays an important role in neuron differentiation and migration, decreased in mice infected by Zika during pregnancy.

NewsMosquito-controlling bacteria might also enhance insect fertility
A new study reveals biological mechanisms by which a specific strain of bacteria in the Wolbachia genus might enhance the fertility of the insects it infects - with potentially important implications for mosquito-control strategies.

NewsChanges in soil organisms in crop rotation farmland accessed by DNA metabarcoding
Researchers using DNA metabarcoding to analyze changes in the composition of soil organisms in corn-cabbage rotation fields found that the soil biota are unexpectedly easily altered by the soil environment, cultivation history and crops.

NewsGut fungi trigger long-lasting severe COVID-19 immune response
Researchers have found that the growth of fungi in the intestinal tract, particularly strains of Candida albicans yeast, trigger an upsurge in immune cells whose actions can exacerbate lung damage.

NewsClimate change is increasing risk of high toxin concentrations in Northern US lakes
As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, with water temperatures of 20 to 25 degrees Celsius at greatest risk for developing dangerous levels of a common algae-produced toxin.

NewsLactate-producing bacteria inside tumors promote resistance to radiation therapy
Researchers have discovered that lactate-producing intratumoral bacteria drives resistance to radiation therapy, suggesting that lactic acid-producing bacteria present in various cancers may serve as novel therapeutic targets.
-
NewsOral pathogen increases heart attack damage
Researchers have found that a periodontal pathogen, Porphyromonas gingivalis, inhibits autophagosome–lysosome fusion, and can therefore worsen cardiac remodeling and cause cardiac rupture after myocardial infarction.

NewsStudy supports potential for injectable ‘chemical vaccine’ for malaria using atovaquone
Researchers demonstrate in mouse model that key mutation that renders malaria parasites resistant to atovaquone also makes them non-transmissible via mosquitoes.
-
NewsBroad-spectrum antiviral candidate targets dengue and SARS-CoV-2
A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized.
-
NewsGut microbiota-derived 7-DHC tackles circadian rhythm disorders and IBD
Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract categorized into ulcerative colitis and Crohn’s disease. Currently, aminosalicylates, glucocorticoids, immunomodulating drugs, and biological agents are common strategies for the treatment of IBD. The efficacy of these therapies is limited, however, and they are ...

NewsPotato supplement modifies gut microbiome, with implications for bone marrow transplants
Researchers at Baylor College of Medicine and the University of Michigan conducted a phase I pilot study to assess the feasibility of using potato starch as a dietary intervention to modify the gut microbiome in bone marrow transplant patients. The study, which appears in the journal Nature ...

NewsSoil carried on sea freight loaded with dangerous plant diseases
Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects,, confirming that shipping containers provide a pathway for the movement of exotic species.

NewsAntimicrobial peptides modulate lung injury by altering the intestinal microbiota
Researchers have identified a gut-lung axis driven by intestinal antimicrobial peptide expression and mediated by the intestinal microbiota that is linked to lung injury in newborns.
