Summary: Blocking the activity of the reactor called the aryl hydrocarbon receptor in T cells resulted in both a decrease in inflammation and recovery in mouse models of multiple sclerosis.

University of Virginia Health neuroscientists have discovered a potential way to disrupt the chronic inflammation responsible for multiple sclerosis.

The Planck Temperature – Absolute Hot: What is the hottest temperature possible.

Today I’m going to look at the Planck Temperature and it’s about to get very strange. Let’s find out more.

Planck temperature is what we think is the highest temperature possible. It is the temperature at which our understanding of the universe breaks.
In this video we’re going to try to imagine just how hot that is, and what the implications of this value are. In order to do this, we’re going to look at some other very hot things to compare.

A new paper has proposed an absolutely wild idea. What if aliens are creating black holes to use as quantum storage? It sounds crazy, but some scientists say it could give us a solution to the Fermi Paradox, which essentially states that if life is common in our universe, why have we not found evidence of it beyond Earth?

This paradox has caused quite a few ripples throughout the scientific community, especially within parts that believe alien life is out there, just waiting to be discovered. The new paper has yet to be peer-reviewed, but it was created by a team of German and Georgian scientists who say we may be looking in the wrong direction in our search for alien life.

Currently, we rely on radio signals to search for signs of life out in the universe. But, these researchers suggest that we should instead approach black holes as if alien civilizations created them as massive quantum computers to store data in. As such, we should be looking for technosignatures emanating from megastructures like pulsars, white dwarf stars, and black holes.

Our DNA holds thousands of dead genes and we’ve only just begun to unravel their stories. But one thing is already clear: we’re not just defined by the genes that we’ve gained over the course of our evolution, but also by the genes that we’ve lost along the way.
