New research findings indicate that exposure to even low levels of arsenic poses significant health risks, including an increased risk of kidney cancer.
All people are unique — also in the gut
A new study increases our knowledge about the gut and the life of gut bacteria. The study shows, among other things, that changes in the gut environment have an impact on the composition and activity of gut bacteria. Ultimately, this may help explain why we all have different gut bacteria...
Magnetic Tornado Is Stirring up the Haze at Jupiter’s Poles
Unusual magnetically driven vortices may be generating Earth-size concentrations of hydrocarbon haze.
Can We Avert the Looming Food Crisis of Climate Change?
Mathematical model captures the relationship between carbon dioxide, temperature, human population, and crop growth—and reveals a critical threshold.
It Might Be Wrecking the Climate, but Co₂ Is Actually Good for Your Cells
University of Utah chemists discover how bicarbonate can protect cells from oxidative stress in a study that challenges how cell damage has been studied for decades.
A fossil first: Scientists find 1.5-million-year-old footprints of two different species of human ancestors at same spot
More than a million years ago, on a hot savannah teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food. Scientists know this because they have examined 1.5-million-year-old fossils...
Satellite evidence bolsters case that climate change caused mass elephant die-off
A new study has provided further evidence that the deaths of 350 African elephants in Botswana during 2020 were the result of drinking from water holes where toxic algae populations had exploded due to climate change.
Conserving Nature can Shield Cities From Floods
Picture a forest meadow, a patch of wetland or a stretch of grassland. These quiet spaces, so often overlooked, could be the key to protecting Canada’s cities from floods.
Forest Damage Caused by Global Warming can be Predicted
“Koli is a special case in many respects. It is a visible destination, a national landscape and a national park visited by many people,” says University Lecturer Olli-Pekka Tikkanen of the School of Forest Sciences at the University of Eastern Finland.
Specific ‘Forever Chemical’ Found at Unexpected Levels in Firefighting Foam
A new study has revealed there may be a significant underestimation of a specific type of PFAS ‘forever chemical’ in the environment.
