NewsVitamin B12 adaptability in Antarctic algae has implications for climate change
A new study shows that the algae Phaeocystis antarctica has the ability to survive without B12, something that computer analysis of genome sequences had incorrectly indicated.

NewsMicrobial division of labor produces higher biofuel yields
Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels, using careful timing and a tight division of labor among synthetic yeast strains.

NewsNew research finds that dust in atmosphere is feeding algae in mountain lakes
Dust deposition from the atmosphere acts as a fertilizer for algae in mountain headwaters, broadening its growth tolerance against other stressors, a new study shows.

NewsResearchers improve climate predictions by unlocking secrets of soil microbes
Scientists are using the DNA from soil microbes to model how they function and use carbon, ultimately helping to advance the accuracy of climate models.

NewsUnique tumor-related bacteria tied to young-onset colorectal cancer, study reveals
New research has mapped changes in tumor-related bacteria to uncover potential new strategies to combat the rise of young-onset colorectal cancer (CRC) in people under the age of 50.

NewsNew technology unscrambles the chatter of microbes
Using a database of over 60,000 microorganisms curated by researchers from across the globe, the new search tool instantly matches microbes to the metabolites they produce.

NewsFungal disease endangers wheat production as climate change bites
Researchers have shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.

NewsSurgeon-scientist studying sinus microbiome in chronic rhinosinusitis patients
A surgeon-scientist is leading a multi-institutional grant investigating the role of the sinus microbiome in chronic rhinosinusitis, an inflammatory disease that causes the lining of the sinuses to swell.

NewsScientists spot an ultra-fast movement on surface of HIV virus
Investigators catch ultra-fast HIV docking mechanism in the act, giving them a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine.

NewsArrangement of bacteria in biofilms affects their sensitivity to antibiotics
New research shows that bacteria that form biofilms actually have a highly structured arrangement within those slimy matrices.

NewsResearch to advance understanding of deadly disease that affects premature babies
Three researchers have earned more than $5 million in grant money to study causes and potential treatments for necrotizing enterocolitis, a deadly intestinal disease that primarily affects infants born prematurely.

NewsTiny tornadoes around leaves spread deadly plant pathogens
A new study is the first to analyze plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse pathogens.
-
NewsModified phage DNA can kill deadly pathogens
DNA modified from a bacteriophage and put inside Pseudomonas aeruginosa was found to bypass the pathogen’s defense mechanisms to assemble into virions, which sliced through the bacterium’s cell to kill it.

NewsFungal-rich soil may improve green roofs
Active management of green roof mycorrhizal fungi accelerates soil development faster than if mycorrhizal fungal communities are left to passively reestablish on their own, a new study shows.

NewsGreen alternative for treating Streptococcus iniae bacteria in hybrid striped bass
Scientists at the United States Department of Agriculture (USDA)’s Agricultural Research Service (ARS) have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.

NewsSwitching to vegan or ketogenic diet rapidly impacts immune system - and gut microbiome
A study found that switching to a vegan diet prompted responses linked to innate immunity, while the keto diet elicited responses associated with adaptive immunity, along with metabolic changes and shifts in the gut microbiomes.

NewsLifetime of ‘biodegradable’ straws in the ocean is 8-20 months, study finds
Researchers found that some commercial bioplastic or paper straws might disintegrate within eight to 20 months in coastal ocean systems and switching to foam makes a major difference.
