New Algorithm Decodes Cause and Effect in Complex Systems

The top panel shows a view of the inside of a neuron where C16 fatty acid derived from palm oil is being synthesized into ceramide C16 (CerC16), which impairs mitochondrial function and results in more severe disease course. The bottom panel shows the same scenario in a mouse with genetic deletions of the ceramide enzymes CerS5 and CerS6. The neurons in these mice do not synthesize Cer C16 from palm oil, resulting in milder disease course.

Hubble and Webb Observations of Vega Circumstellar Debris Disk. [left]-A Hubble Space Telescope false-color view of a 100-billion-mile-wide disk of dust around the summer star Vega. Hubble detects reflected light from dust that is the size of smoke particles largely in a halo on the periphery of the disk. The disk is very smooth, with no evidence of embedded large planets. The black spot at the center blocks out the bright glow of the hot young star. [right]-The James Webb Space Telescope resolves the glow of warm dust in a disk halo, at 23 billion miles out. The outer disk (analogous to the solar system’s Kuiper Belt) extends from 7 billion miles to 15 billion miles. The inner disk extends from the inner edge of the outer disk down to close proximity to the star. There is a notable dip in surface brightness of the inner disk from approximately 3.7 to 7.2 billion miles. The black spot at the center is due to lack of data from saturation.
