From CNN, Don Lincoln, Jan. 13, 2023: Because of the Montreal Protocol signed in 1987, which regulated the consumption and production of almost 100 chemicals called chlorofluorocarbons, use of CFCs has decreased by 99%, and the Earth’s ozone layer is on track to recover in the coming decades.

From Big Think, Jan. 10, 2023: While the Standard Model is the best theory available in modern physics to explain subatomic physics, it cannot explain why antimatter isn’t observed in nature or provide an explanation for dark matter and dark energy. Don Lincoln explains how recent measurements of muons and electrons are propelling the idea that there may be undiscovered laws of nature yet to discover.

From Big Think, Jan. 6, 2023: While astronomers debate the existence of dark matter, Don Lincoln breaks down a new paper published in Nature Astronomy that claims to debunk a key observation that strengthens the case that the Universe is full of unseen matter.

From CNN Opinion, Dec. 14, 2022: Don Lincoln examines the result from the National Ignition Facility at Lawrence Livermore National Laboratory that fusing elements released more energy than the lasers supplied. While this is a monumental step for science and a spectacular technical achievement, the process has to be repeated again and again and engineers need to construct a containment structure that can survive the bath of neutrons that a functional fusion generator will create.

From the Big Think, Nov. 30, 2022: Don Lincoln discusses that while the Universe we see is made solely of matter, there is no explanation for this fundamental asymmetry.
Understanding why the Universe was created with more matter than antimatter is key to understanding why anything exists.

From the Big Think, November 14, 2022: Gaia BH1 is the closest black hole to Earth that scientists have ever discovered at just 1,600 light years away. Fermilab’s Don Lincoln examines that by looking at the behavior of a star near the black hole, how astronomers might be able to determine the black hole was there, despite never seeing it directly.

From Big Think, Nov. 2, 2022: Don Lincoln explores Hubble tension, two very precise yet conflicting estimates of the rate at which the Universe is expanding. While the of Universe expansion is consistent, the two ways in which this is measured begs the question if something is missing in cosmology theory.
