An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications. Their findings were published in the journal Scientific Reports.  The ionosphere is the region of the Earth's upper atmosphere where molecules and atoms are ionized by solar radiation, creating positively charged ions. The area with the highest concentration of ionized particles is called the F-region, an area 150 to 800 km above the Earth's surface. The F-region plays ...

Investigators from the Smidt Heart Institute at Cedars-Sinai found that women who experience an adverse pregnancy outcome—such as gestational hypertension, preeclampsia or preterm birth—have a higher risk of developing stroke in their lifetime, and at a younger age. The findings, published today in the peer-reviewed journal Stroke, also found that compared to women with one uncomplicated pregnancy, a woman who had two or more pregnancies impacted by an adverse pregnancy outcome had a twofold higher increase of stroke. “We understand from past studies in the U.S. that women have a greater risk of experiencing a stroke and a disproportionate ...

Snow is melting earlier, and more rain is falling instead of snow in the mountain ranges of the Western U.S. and Canada, leading to a leaner snowpack that could impact agriculture, wildfire risk and municipal water supplies come summer, according to a new study from the University of Colorado Boulder.
