Little is known about the ecological relationship of Vibrio bacteria with Sargassum. Evidence also is sparse as to whether vibrios colonizing plastic marine debris and Sargassum could potentially infect humans. As summer kicks off and efforts are underway to find solutions to repurpose Sargassum, could these substrates pose a triple threat to public health? Results of a study representing the first Vibrio spp. genome assembled from plastic finds Vibrio pathogens have the unique ability to “stick” to microplastics, harboring potent opportunistic pathogens.
In suburban backyards and at family picnic gatherings across the United States, mosquitoes are a common pest. People are most likely to get bitten by mosquitoes during the warm and lazy summer months, says Katie Westby, vector and disease ecologist at Tyson Research Center, Washington University in St. Louis’ environmental field station in Eureka, Mo.

New research shows that smartphone activity actually increases during visits outdoors to city parks—a finding that contradicts popular notions. Thanks to two years of unparalleled access to 700 study participants' smartphone data, the study is the first to show that young adults now spend far more time on their smartphone screens than in nature. The study finds that people who visit forests or nature preserves experience significant declines in screen time, compared to visits to urban locations for the same duration.
To give the authorities a cross-sectoral view of a city’s nutrient sink status, the researchers identified and analysed a range of waste flows. Their approach distinguished four nested spatial levels: the urban area; the potential territorial recycling system; the country and the international level. Based on that analysis, the researchers focused on the origin and fate of those nutrient-containing waste flows.
Researchers at the University of Massachusetts Amherst recently published a study in the journal PLOS Water that focuses on the Sudbury-Assabet and Concord watershed in eastern Massachusetts, and which links hydrological changes, including floods, drought and runoff, to changing patterns of land use.
As the northern hemisphere heads into summer, we may be in for a COVID-19 reprieve.

Air pollution has been shown to have a negative effect on the prognosis of ischemic stroke, or stroke caused by reduced blood flow to the brain, but the exact mechanism is unknown. A team of researchers recently conducted a study to determine whether or not increased inflammation of the brain, also known as neuroinflammation, is the main culprit.
Humans smell. Each and every person has a unique body odor. People have been using commercial products to alter their scent for generations. From soaps to perfumes, people gravitate to floral and fruity smells. Whether we think these smells are good or bad is of little consequence to mosquitoes, transmitters of diseases that kill hundreds of thousands of people each year.
Living in areas with high numbers of fast food, alcohol and gambling outlets, can negatively impact young people’s mental health, new research shows.
The coqui frog, one of Puerto Rico’s most iconic animals, gets its name from its distinctive two-note call, “co-qui,” which can be heard throughout the island every night. The males produce these calls to mark their territory and ward away rivals, but scientists can use them to study the changing climate. At the 184th ASA Meeting, Peter Narins of the University of California, Los Angeles will describe changes in the coqui calls over a 23-year period. Every frog call had grown higher in pitch, indicating a mini-migration that corresponds with the temperature shift induced by climate change.
Lung cancer is the most common cause of cancer-related deaths in North America. Although cigarette smoking remains the main risk factor for lung cancer development, the importance of environmental factors such as pollution and poor air quality is becoming increasingly recognized.

A study in Florida Bay, one of the largest global contiguous seagrass systems, examined if a phytotoxin that accumulates as seagrass ecosystems become more enriched in nutrients prevents a marine seagrass, turtlegrass, from recruiting into open bare sediment following die-off events. While they do “bounce back,” long-term monitoring indicates the timeframe for recovery after major die-off events is at least a decade. Turtlegrass can successfully recruit into open bare sediment following die-off events due to biomass partitioning.
The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.
