Earth's blobs are remnants of an ancient planetary collision
In the 1980s, geophysicists made a startling discovery: Two continent-sized blobs of unusual material were found deep near the center of the Earth, one beneath the African continent and one beneath the Pacific Ocean.Each blob is twice the size of the moon, and research over the last decade has shown that they are…

Training immune cells to remove ‘trash’ helps resolve lung inflammation
Inflammation is a standard part of our bodies’ immune system response. But sometimes this response becomes hyperactivated in our lungs, causing inflammation to continue unchecked, which can be fatal. Many deaths from COVID-19 have been due to excessive inflammation, which results in acute lung injury.
