NewsFoxes and birds could be ‘early warning system’ to survey spread of antibiotic resistance into ecosystems
Wildlife monitoring could alert us to the spread of highly antibiotic resistant bacteria into unexposed ecosystems, highlighting a potential public health strategy.

NewsAncient tooth reveals the bacterium responsible for scarlet fever was not introduced to the Americas by Europeans
A research team has identified the Streptococcus pyogenes bacterium in a pre-Columbian Bolivian mummy and, for the first time, reconstructed the genome of this centuries-old pathogen.

NewsThe giants of the reef: New citizen science project races to document centennial corals
Coral reefs hide “scientific treasures” that have survived for centuries, yet many of these giant, ancient organisms remain largely unknown to science. A new study introduces a pioneering citizen-science initiative to find these giant coral colonies before they are lost to escalating global pressures.

NewsNovel research reveals the active role that skin cells play in rabies infection
A new study provides direct evidence that keratinocytes can support viral replication and transmit the rabies virus to neurons. The investigators offer a mechanistic explanation for how superficial skin exposures from scratches or minor bites by dogs and bats can lead to neuroinvasion.

NewsStudy reveals new way to strengthen immunity against the flu
A new vaccine model targets epitopes, specific but distinct regions of the protein on the surface of the influenza virus. The model includes different versions of epitopes in hopes of redirecting how the immune system responds.
-
NewsResearchers synthesize photosynthetic molecule found in bacteria
Researchers have successfully synthesized bacteriochlorophyll a, a photosynthetic pigment found in bacteria which absorbs infrared light. The work represents the first chemical synthesis of this molecule and could give scientists deeper insights into photosynthetic function and photosynthetic energy.

NewsPoor hygiene and food handling practices increase the risk of bacterial outbreaks in Brazilian households
A significant number of Brazilians engage in improper food hygiene and handling practices at home. Examples include washing meat in the kitchen sink and failing to properly wash vegetables.

NewsAs syphilis cases rise, study links infection with higher risk of stroke, heart attack and other serious cardiovascular problems
Adults with later-stage syphilis are more likely to develop major cardiovascular problems – including stroke, heart attack or aortic aneurysm – than similar patients without the infection. The increased risk is primarily found in those whose infection progressed longer than a year.
-
NewsStudy: Microbes show almost universal potential for biodegrading plastics
Researchers have identified more than 600,000 microbial proteins capable of breaking down natural and synthetic plastics, revealing a far broader biodegradation potential across microbes than previously known.
-
NewsSelf-propulsion or slow diffusion: How bacteria, cells, and colloids respond to stimuli
One enables them to quickly leave an environment; the other helps them move toward where they are needed. In microorganisms, as well as in artificial structures, these are the movements triggered in response to incoming and outgoing signals.
-
NewsFirst continent-wide map of dominant avian influenza strain explains its spread
Scientists provided the most complete view of bird flu’s spread through wild bird populations across North America, explaining how the dominant strain advanced, maintaining the risk of human infections.
-
NewsStudy reveals genome-wide host–virus genetic interactions in cancer risk
Researchers report a major advance in understanding how interactions between human and viral genomes shape disease risk. They found that variations in the Epstein–Barr virus, together with a specific immune-related gene (HLA-A*11:01), strongly influence the risk of nasopharyngeal cancer.

NewsMBL scientist Alexandra Z. Worden honored with a Guggenheim Fellowship
Alexandra Z. Worden, Senior Scientist in the Bay Paul Center at the Marine Biological Laboratory and a Professor in the Department of the Geophysical Sciences at the University of Chicago was awarded a Guggenheim Fellowship this week, in recognition of her groundbreaking research in ocean biogeochemistry.

NewsGut microbiome serves as key driver for bacterial infection outcomes for fatty liver disease
Researchers found that metabolic dysfunction–associated steatotic liver disease dramatically worsens outcomes following infection with Vibrio vulnificus, a potentially life-threatening foodborne bacterium commonly associated with seafood consumption.
-
NewsExtend vaccination opportunities and involve community members in communicating about vaccines to boost uptake, say researchers
Extending vaccination opportunities, involving community members alongside healthcare professionals in communicating about vaccines, and providing financial incentives are among the most effective ways to increase vaccine uptake.
-
NewsAfrican swine fever is quietly spreading across Nepal’s pig sector
A new study provides the first comprehensive analysis of African swine fever outbreaks in Nepal, revealing a disease that has quietly dismantled livelihoods, disrupted food security, and exposed deep gaps in the country’s animal health system — with no vaccine in sight.
-
NewsHow soil microbes adapt to life in lakes
Researchers have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits – but others reduce the size of their genome and lose some functions in order to successfully move to a new home.

News‘Safe’ fertilizer linked to extreme water quality loss in Canadian Prairies
Research has found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Urea added to farm ponds increased growth of algae to levels 10 times higher than seen in other damaged ecosystems, such as Lake Winnipeg in Manitoba.

NewsIn developing immunity to allergens, a little ‘dirty’ goes a long way
Exposure to diverse microbes and proteins early in life creates broad immune memory and a specific antibody that helps block allergic reactions later in life. Rather than overreacting to harmless allergens, an experienced immune system responds in a balanced way.

NewsGene sheds light on how parasites exit host cells
Researchers have elucidated the parasite exit process - known as egress - after identifying an essential gene, MIC11. To clearly explain egress, the behaviors of Toxoplasma gondii were assessed.
