NewsNew hydrogel biomaterial mimics human tissue and fights bacteria
Scientists have created a new material, belonging to a family of substances called hydrogels, that could change the way human tissue can be grown in the lab and used in medical procedures.

NewsNew advances in genomic surveillance tech could slow the spread of deadly ‘superbugs’
Harnessing new advances in genomic surveillance technology could help detect the rise of deadly ‘superbugs’ and slow their evolution and spread, improving global health outcomes, a new study suggests.

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.

NewsOxygen vacancy boosting Fenton reaction helps to fight bacterial infection in bone scaffold
A groundbreaking approach to address bacterial infection in artificial bone transplantation works by enriching H2O2 from the microenvironment and amplifying the ability of Fenton reaction to functionalize bone scaffold with antibacterial properties.

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.

NewsSoft, living materials made with algae glow under stress
A team of researchers has developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting, and deriving their luminescence from single-celled algae known as dinoflagellates.

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.

NewsTechnique restores the function of a human cell surface protein in yeast cells
Scientists report a technique that could promote the use of yeast as a convenient platform to study human proteins and develop new drugs.

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.

NewsSpaceflight could alter behaviour of human microbiome, bobtail squid study suggests
Microgravity changes how effectively symbiotic bacteria colonise the light organ of the bobtail squid, according to a new study which has implications for how the human microbiome may respond to spaceflight. Source: Joseph Emhof Bobtail squid just after hatching The research by a University of Florida team, ...

NewsDeep dive into the gut unlocks new disease treatments
Researchers say it’s not only possible to map just what species are in the gut microbiome but how they interact and how that can affect the whole body.

NewsGenetic fingerprint suggests cutaneous leishmaniasis may be gaining foothold in US
Analysis reveals DNA evidence of a US-acquired strain of cutaneous leishmaniasis - the prospect of a growing threat comes amidst concerns that domestic sand flies could acquire a deadly form of the disease via dog imports.

News‘Subway map’ of Lyme disease pathways IDs potential treatment targets
Researchers have developed a genome-scale metabolic model of key metabolic activities of the bacterium that causes Lyme disease, successfully identifying two compounds that selectively target routes only used by Lyme disease to infect a host.
