Is this why some people see the cheap LED lights flicker and some don't?
Scientists discover speed of visual perception ranges widely in humans
Apr 2024, phys.org
There is considerable variation among people in their temporal resolution, meaning some people effectively see more "images per second" than others.To quantify this, the scientists used the "critical flicker fusion threshold," a measure for the maximum frequency at which an individual can perceive a flickering light source.Some participants in the experiment indicated they saw the light as completely still when it was in fact flashing about 35 times per second, while others were still able to perceive the flashing at rates of over 60 times per second.

Brain–computer interface experiments first to decode words 'spoken' entirely in the brain in real time

The electrodes were implanted in the supramarginal gyrus, a part of the brain that recent research suggests is involved in subvocal speech.

This Ecuadorian forest thrived amid deforestation after being granted legal rights
Jun 2024, BBC News
Rights of Nature Movement - In 2008, Ecuador became the first country to change its constitution to state that nature has the same rights as people. The change was led by Ecuador's Indigenous movement, and marked one of the first major steps in what has become known as the 'rights of nature' movement – a movement centred on a legal framework that recognises the inherent right of the natural world to the same protections as people and corporations.The rights of nature movement "is a move to transform natural entities from objects to subjects, in courts and in front of the law", says Jacqueline Gallant from New York University's School of Law's Earth Rights Advocacy Clinic. "But in a much broader sense, it's been a movement to reanimate and recentre nature as a subject of intrinsic worth," Gallant explains. This is in contrast, she says, to the Western view of nature as "an inanimate backdrop against which the drama of human activity unfolds".
