Exposure to even moderate levels of radon linked to increased risk of stroke

Exposure to even moderate levels of radon linked to increased risk of stroke

Radon is the second leading cause of lung cancer. Now a new study has found exposure to this invisible, odorless gas is also linked to an increased risk of stroke. The study, which examined exposures in middle age to older female participants, found an increased risk of stroke among those exposed to high and even … Read more

‘Tiny tornadoes’ around leaves spread deadly plant pathogens

‘Tiny tornadoes’ around leaves spread deadly plant pathogens

A new study led by Cornell University is the first to analyze plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse pathogens. When raindrops hit a leaf of a wheat plant infected with rust — a pathogenic spore that has decimated crops globally — the leaf flutters, creating tiny … Read more

Death toll shows extreme air pollution events a growing urban threat

Death toll shows extreme air pollution events a growing urban threat

New Curtin University-led research has estimated that 1454 avoidable deaths (one person every five days) occurred in Australian capital cities in the past 20 years because of fine particle air pollution from extreme events such as bushfires and dust storms, wood-heater smoke or industrial accidents. The study also found that nearly one-third of deaths from … Read more

Fungal-rich soil may improve green roofs

Fungal-rich soil may improve green roofs

Green roofs have become increasingly popular thanks to their benefits related to climate adaptation, mitigation, and urban biodiversity management. These vegetated surfaces on the rooftops of buildings absorb excess storm water, reduce energy use by insulating buildings, and cool neighborhoods, tempering urban heat islands, while also creating urban habitats for plants, pollinators, and wildlife. But, … Read more

Ambitious roadmap for circular carbon plastics economy

Ambitious roadmap for circular carbon plastics economy

Researchers from the Oxford Martin Programme on the Future of Plastics, University of Oxford, have outlined ambitious targets to help deliver a sustainable and net zero plastic economy. In a paper published in Nature, the authors argue for a rethinking of the technical, economic, and policy paradigms that have entrenched the status-quo, one of rising … Read more

Using CRISPR technology, researchers succeed in growing tomatoes that consume less water without compromising yield

Using CRISPR technology, researchers succeed in growing tomatoes that consume less water without compromising yield

A new discovery by Tel Aviv University has succeeded in cultivating and characterizing tomato varieties with higher water use efficiency without compromising yield. The researchers, employing CRISPR genetic editing technology, were able to grow tomatoes that consume less water while preserving yield, quality, and taste. The research was conducted in the laboratories of Prof. Shaul … Read more

Some plastic straws degrade quicker than others, new study shows

Some plastic straws degrade quicker than others, new study shows

Straws are one of the most common plastic waste products found on coastlines. As more and more plastic products are being produced, consumed, and disposed of, scientists and manufacturers are developing alternative materials that work equally as well, and don’t contribute to persistent plastic pollution in the environment. But not all plastics are created the … Read more

Prenatal air pollution exposure linked to severe newborn respiratory distress

Prenatal air pollution exposure linked to severe newborn respiratory distress

Prenatal exposure to air pollution increases the risk of severe respiratory distress in newborn babies, according to new research conducted at the Penn State College of Medicine in collaboration with the Maternal-Infant Research on Environmental Chemicals (MIREC) Study led by Health Canada. The risk increases with exposure specifically to fine particulate matter (PM2.5) and nitrogen … Read more

Rising sea levels could lead to more methane emitted from wetlands

Rising sea levels could lead to more methane emitted from wetlands

As sea levels rise due to global warming, ecosystems are being altered. One small silver lining, scientists believed, was that the tidal wetlands found in estuaries might produce less methane — a potent greenhouse gas — as the increasing influx of seawater makes these habitats less hospitable to methane-producing microbes. However, research from biologists at … Read more
