Getting to the bottom of Arctic landslides

Erosion of the frozen soil of Arctic regions, known as permafrost, is creating large areas of subsidence, which has catastrophic impact in these regions sensitive to climate change. As the mechanisms behind these geological events are poorly understood, researchers from the Géosciences Paris Sud (GEOPS) laboratory (CNRS / Université Paris-Saclay), in cooperation with the Melnikov […]

Pfizer’s COVID-19 vaccine starts to work just 10 days after 1st dose

Pfizer’s new COVID-19 vaccine starts to protect people from the novel coronavirus just 10 days after the first dose, according to new documents from the U.S. Food and Drug Administration (FDA). The documents were released on Tuesday (Dec. 8), two days before a meeting of the FDA’s vaccine advisory panel, which will vote on whether […]

Understanding COVID-19 infection and possible mutations — ScienceDaily

The binding of a SARS-CoV-2 virus surface protein spike — a projection from the spherical virus particle — to the human cell surface protein ACE2 is the first step to infection that may lead to COVID-19 disease. Penn State researchers computationally assessed how changes to the virus spike makeup can affect binding with ACE2 and […]

Lyme Disease and the Dangers of the Forest Edge

Lyme disease was first identified in 1976 in Lyme, Conn. Since then, the disease has become more common in North America, spreading throughout the northeastern and midwestern United States, creeping north into Canada and south into Virginia. About 30,000 cases are reported each year, although it’s estimated that the true prevalence of the […]

“Pink tax” hurts female consumers, but electing more women combats it

Credit: CC0 Public Domain The wage gap between men and women is no secret, but another form of gender discrimination directly and disproportionately affects women worldwide: the “pink tax” imposed by import tariffs that target female products. But new Rice University research concludes the “pink tax” is generally lower in countries where more women are […]

How poor oral hygiene may result in metabolic syndrome — ScienceDaily

Periodontal or gum disease is known to be a significant risk factor of metabolic syndrome, a group of conditions increasing the risk for heart disease and diabetes. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered that infection with Porphyromonas gingivalis, the bacterium causing periodontal disease, causes skeletal muscle metabolic dysfunction, […]

Feedback Loops of Fire Activity and Climate Change in Canada

Wildfires burned more than 7,750 square kilometers of Alberta’s forests last year. New research indicates the conflagrations are part of a pattern showing increased average burned areas every year since 1970, and climate change is poised to accelerate this trend. Ellen Whitman, a forest fire research scientist from Natural Resources Canada, used historical […]
