An analysis of 12 years of data collected from over 500 hospitals in 25 different states shows that weather, geographic location, and urban or rural location all appear to influence hospitalizations for waterborne infectious diseases.

For a long time, scientists assumed that jellies (commonly known as jellyfish) were a dead-end food source for predatory fish. However, a team has now discovered that fish in Greenland waters do indeed feed on jellyfish. In two of the analyzed species, they even made up the majority of the food. The results suggest that the role of jellyfish as prey in marine food webs should be reconsidered, especially in regards to the fact that they could be profiting from climate change and spreading farther and farther north.

Being born in autumn or winter is associated with asthma and allergic rhinitis in Finland, a new registry-based study shows.

In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. The study estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.

Research suggests that, in some cases, boosting urban soil health with compost and treated manure may reduce the amount of pathogenic and anti-biotic resistant bacteria.

Using nighttime lightdata from NASA, remote sensing, official outage records and census information, a study reveals notable differences in power-restoration rates between urbanized and rural areas and between disadvantaged and more affluent communities after Hurricane Michael in Florida's Panhandle. Block groups with higher proportions of minorities, multi-family housing units, rural locations, and households receiving public assistance experienced slower restoration of power compared to urban and more affluent neighborhoods.

An international research team has discovered that comammox bacteria, first identified by them in 2015, can grow using guanidine, a nitrogen-rich organic compound, as their sole energy and nitrogen source. This unique ability opens new avenues for targeted cultivation of these enigmatic microbes and could also provide a key to reducing agricultural nitrous oxide emissions.

Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.

Linked to cardiovascular and respiratory diseases in people, nanoplastics continue to build up, largely unnoticed, in the world's bodies of water. The challenge remains to develop a cost-effective solution to get rid of nanoplastics while leaving clean water behind. That's where Mizzou comes in. Recently, researchers created a new liquid-based solution that eliminates more than 98% of these microscopic plastic particles from water.

Chemists developed a way to synthesize complex molecules called oligocyclotryptamines, originally found in plants, which could hold potential as antibiotics, analgesics, or anticancer drugs.

A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.

A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.

Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.

The smaller carbon footprint, or wheel print, of automatic delivery robots can encourage consumers to use them when ordering food, according to a new study. The suitcase-sized, self-driving electric vehicles are much greener than many traditional food delivery methods because they have low, or even zero, carbon emissions. In this study, participants who had more environmental awareness and knowledge about carbon emissions were more likely to choose the robots as a delivery method. The green influence went away though when people perceived the robots as a high-risk choice -- meaning they worried that their food would be late, cold or otherwise spoiled before it arrived.

Food, feed, fiber, and bioenergy: The demand for agricultural raw materials is rising. How can additional cultivation areas be reconciled with nature conservation? Researchers have developed a land-use model that provides answers.

Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.
