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.

How Correlated Are You?
This post is an offshoot from Chapter 1 of Probably Overthinking It, which is available for pre-order now! Suppose you measure the arm and leg lengths of 4082 people. You would expect those measurements to be correlated, and you would be right. In the ANSUR-II dataset, among male members of the armed forces, this…

Scientists unveil fire-safe fuel
UC Riverside chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn’t react to flames and cannot start accidental fires during storage or transport, it is a “safe” liquid fuel.

Geneticists develop novel gene therapy for glaucoma
The gene therapeutic approach, which shows promise for treating age related macular degeneration (AMD), may also be effective in treating other eye conditions such as glaucoma. It provided benefit in three additional models of mitochondrial dysfunction, including cells taken from patients living with an optic…
