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.

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.

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 ...

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.

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.

NewsResearchers discover associations among PTSD, diet, and the gut microbiome
A new study suggests that adhering to a Mediterranean diet may alleviate or prevent posttraumatic stress disorder (PTSD) symptoms.

NewsYeast speeds discovery of medicinal compounds in plants
Researchers have harnessed the power of baker’s yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.

NewsGermicidal UV lights could be producing indoor air pollutants, study finds
While useful for killing pathogens including SARS-CoV-2, the lights may cause unwanted chemical reactions and should be used with ventilation, researchers say.

NewsResearchers receive $423,500 for study to improve outcomes from fungal infections
Researchers have received a $423,500 for research aimed at reducing disease and mortality rates associated with Aspergillus infections by focusing on the molecular pathways in the fungus that mediate inflammatory host responses.

NewsStudy demonstrates antimicrobial action of polyalthic acid from copaiba oil
Polyalthic acid from copaiba oil is an effective antibacterial and should be used to develop alternative medications that can contribute to the effort to overcome antimicrobial resistance, according to a new study.

NewsFungal infection in the brain produces changes like those seen in Alzheimer’s disease
Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and generates amyloid beta (Ab)-like peptides.
