Antioxidants found to spur cancer growth and metastasis in mice
Vitamin C and other antioxidants stimulate the formation of new blood vessels in lung cancer tumours, a new study from Karolinska Institutet published in The Journal of Clinical Investigation shows. The discovery corroborates the idea that dietary supplements containing antioxidants can accelerate tumour growth and…

Scientists use quantum device to slow chemical process by factor of 100B
In a world-first experimental result, scientists at the University of Sydney have used a quantum computer to coax an atom to behave the same way as a photo-chemical process that underpins the speed of human vision and solar energy harvesting - only at speeds 100 billion times slower than in nature.

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…

How far can you jump from a swing?
In this post I derive the physics of pumping a swing and the physics of jumping from a swing. Then, using both pieces I compute the optimal strategy of jumping from a swing to maximize the traveled distance. I propose this game as a new Olympic sport.

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.
