A history of the electron: JJ and GP Thomson

Posted by in category: particle physics

J.J. Thomson won the Nobel Prize in physics in 1906 showing that the electron is a particle: ironically, his son, G.P. Thomson, won the Nobel Prize in physics in 1937 showing that it is not (or rather that the electron can also behave as a wave)


A tale of two Thomsons.

Thought-to-text chip smaller than Neuralink achieves 91% accuracy

Posted by in categories: computing, Elon Musk, neuroscience

The brain-machine interface race is on. While Elon Musk’s Neuralink has garnered most of the headlines in this field, a new small and thin chip out of Switzerland makes it look downright clunky by comparison. It also works impressively well.

The chip has been developed by researchers at the Ecole Polytechnique Federale de Lausanne (EPFL) and represents a leap forward in the sizzling space of brain-machine-interfaces (BMIs) – devices that are able to read activity in the brain and translate it into real-world output such as text on a screen. That’s because this particular device – known as a miniaturized brain-machine interface (MiBMI) – is extremely small, consisting of two thin chips measuring just 8 mm2 total. By comparison, Elon Musk’s Neuralink device clocks in at comparatively gargantuan size of about 23 × 8 mm (about 0.3 x .9 in).

Additionally, the EPFL chipset uses very little power, is reported to be minimally invasive, and consists of a fully integrated system that processes data in real time. That’s different from Neuralink, which requires the insertion of 64 electrodes into the brain and carries out its processing via an app located on a device outside of the brain.

Scientists Say They’ve Figured Out How to Regenerate Knee Cartilage

Posted by in categories: biotech/medical, employment

Scientists at Northwestern University say they’ve invented a goo — yes, a goo — that could open the door to regenerating human knee cartilage, a finding that could eventually lead to new clinical ways to rebuild knee joints and avoid invasive and expensive knee replacement surgeries.

Cartilage is the connective tissue that wraps around joints and bones, working to absorb shock, aid mobility, and protect against painful bone-on-bone friction. These are all tough — and important! — jobs, and yet cartilage doesn’t naturally regenerate on its own. As a result, those with worn-down or damaged cartilage often wind up turning to knee replacement surgery. While effective, that road can be expensive and generally requires a lengthy recovery period.

That’s where the goo might come in.

Brain clocks capture diversity and disparities in aging and dementia across geographically diverse populations

Posted by in categories: life extension, neuroscience

The brain undergoes dynamic functional changes with age1,2,3.


Analyses of neuroimaging datasets from 5,306 participants across 15 countries found generally larger brain-age gaps in Latin American compared with non-Latin American populations, which were influenced by disparities in socioeconomic and health-related factors.

Applied Postmodernism: How “Idea Laundering” is Crippling American Universities

Posted by in category: futurism

A fringe ideology on the far left has taken over academia, suppressing free speech and promoting grievance studies over evidence-based research, with the goal of controlling society and imposing its ideology on others.

Questions to inspire discussion.

Postmodernism Corrupts Academia: The Truth Behind Grievance Studies

Posted by in category: futurism

Certain fields of academia, particularly those influenced by postmodernism and critical theory, have become corrupted by a focus on ideology over truth, leading to a lack of intellectual rigor and a stifling of rational discourse.

Questions to inspire discussion.
