Global warming increases the probability that we’ll be drinking arsenic, especially if we live in Asia. At this point, between 94 million to 220 million people – of whom 94 percent live in Asia – are at risk of drinking…
A new study has confirmed the presence of microplastics in birds of prey, including hawks, ospreys and owls. The accumulation of microplastics in birdsâ digestive systems could lead to poisoning, starvation and death.
(SciComm Services) With major funding from the Heising-Simons Foundation and Alfred P. Sloan Foundation, the film Picture a Scientist is breaking new ground by virtually launching in theaters across North America on June 12th. The independent documentary follows a groundswell of researchers who are writing a new chapter for women scientists. Picture a Scientist will show through June 26 in select theaters nationwide, which are each providing exclusive links to the full film online.
(University of Maryland Baltimore County) Samuel Hulse at UMBC and colleagues have shown for the first time that there is a strong correlation between the complex patterns on male darters and their highly-variable environments. The findings support and expand upon sensory drive theory, which states that the environment influences which sexual signals, like visual patterns, are selected for. Previous sensory drive research looked at simple signals (e.g. colors), but Hulse used Fourier analysis to greatly expand that work.
High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands’ long-term storage of it, even during times of extreme drought.
The microbes that inhabit our bodies are influenced by what we eat, drink, breathe and absorb through our skin, and most of us are chronically exposed to natural and human-made environmental contaminants. Scientists review the research linking dozens of environmental chemicals to changes in the gut microbiome and associated health challenges.
(University of Portsmouth) The skeleton of an extinct ‘fish lizard’ locked in a glass case over 16 feet from the ground for the last 100 years has finally been studied, thanks to a selfie stick on a fishing rod.
Lives have been lost, businesses have been shuttered for good, schools have been closed and millions are stressed out by the effects of coronavirus, but lefty journalists managed to find the “silver lining” to the pandemic — a cure for…
A major transformation in vertebrate evolution took place when breathing shifted from being driven by head and throat muscles — like in fish and frogs — to the torso — like in reptiles and mammals. But what caused the shift? A new study posits that the intermediate step was locomotion. When lizards walk, they bend side-to-side. The ribs and vertebrae are crucial to this movement, and the mechanics follow the same pattern as when they inhale and exhale.
