The relentless threat from wide channels of molten rock forced about 2,000 residents to evacuate. By the end of the eruption, 24 people were injured, 716 […]

Enormous X-ray bubbles balloon from the center of the Milky Way

Two giant, mysterious bubbles spew from the Milky Way’s heart, and now it appears the bubbles may have doubles. Scientists have known for a decade that two bubbles of charged particles, or plasma, flank the plane of the Milky Way. Those structures, known as the Fermi bubbles after the telescope that detected them, are visible […]

Social bubbles and masks more situation-dependent in terms of effectiveness — ScienceDaily

Simon Fraser University professors Paul Tupper and Caroline Colijn have found that physical distancing is universally effective at reducing the spread of COVID-19, while social bubbles and masks are more situation-dependent. The researchers developed a model to test the effectiveness of measures such as physical distancing, masks or social bubbles when used in various settings. […]

Cosmic bubbles may have forged dark matter, new theory suggests

Ballooning cosmic bubbles in our early universe may have led to the current abundance of dark matter, the elusive substance that tugs on the stars, yet emits no light, a new study suggests. The theory, described Oct. 9 in the journal The Physical Review Letters, may explain exactly how dark matter condensed out of the […]
