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.

Ladies and gentlemen, to your attention:
Ukraine’s new Commander-in-Chief Mykhailo Drapatyi, inside this BTR-2 commanding to break through improvised defenses of Russian terrorists in Mariupol 2014.
He is a badass guy, for sure!
2nd Amendment activist and YouTuber Luis Antonio Johnson was shot multiple times by Denver police just minutes after he shot another man during an apparent act of self-defense in downtown Denver.
The incident happened around 2:00 a.m. on May 3, 2026, near the 16th Street Mall. Civilian footage recorded by the 27-year-old man who was shot appears to show him pursuing and threatening Johnson before Johnson opened fire.
Johnson then ran to the vestibule of his nearby apartment building while still holding his handgun. Officers responding to the original gunfire were directed toward him by witnesses who identified him as the shooter.
Police bodycam footage shows officers repeatedly ordering Johnson to drop the gun. As he turned toward them, two officers fired nine rounds combined, striking him multiple times. Some viewers believe the weapon was pointed downward or being lowered when the shots were fired.
Both Johnson and the 27-year-old man survived.
Johnson was initially charged with felony assault, but the serious charge was reportedly reduced after investigators reviewed the civilian footage and circumstances surrounding the first shooting. The Denver District Attorney later determined the officers reasonably believed Johnson posed an immediate threat and cleared them of criminal wrongdoing.
The case shows how quickly a person who may have legally defended himself can still be mistaken for the aggressor when police arrive. After a self-defense shooting, call 911, request medical assistance, clearly describe yourself, stop handling the weapon when it is safe, keep your hands visible and follow every command.
