Congratulations to Sir Roger Penrose and colleagues from Oxford, Ulm and Ben-Gurion Negev Universities for experiments linking Einstein’s gravity with quantum mechanics. They proved equivalence theory which extends spacetime curvature to tiny quantum scales, as Penrose predicted. With larger superpositioned masses they can test Penrose Objective Reduction at times t=h/E, also proposed as the origin of consciousness. Preparations for those experiments are underway.

@FrostyFinances Earnings Quality - About $13.4 billion of reported net income comes from unrealized equity gains (e.g., Intel stake). This noncash, non-operating item inflates the reported P/E, with the real P/E estimated closer to 60x.
Today, NSF released 12 new notices of funding opportunity providing over $1.5 billion for foundational research across the sciences and engineering. https://t.co/dFbK0iRm7K
Using more than 1.4 petabytes of electron microscopy (EM) imaging data, researchers generated a nanoscale-resolution reconstruction of a millimeter-scale fragment of human cerebral cortex, providing an unprecedented view into the structural organization of brain tissue at the supracellular, cellular, and subcellular levels.
The human brain is a vastly complex organ and, to date, little is known about its cellular microstructure, including the synaptic and neural circuits it supports. Disruption of these circuits is known to play a role in myriad brain disorders. Yet studying human brain samples in such great detail comes with a host of challenges, ranging from technological limitations to the availability and preservation of tissue samples from healthy individuals.
In a 2024 Science study, researchers performed a high-resolution EM reconstruction of the ultrastructure of a cubic millimeter of human temporal cortex. According to the authors, the reconstruction contains roughly 57,000 cells, about 230 millimeters of blood vessels, and nearly 150 million synapses, comprising 1400 terabytes of data. The authors generated a three-dimensional reconstruction of nearly every cell and process in the cubic millimeter sample and developed a freely available tool for visualizing and analyzing the vast dataset.
