- After a steady decline from 2007 to 2013 in police registered violent crime among adolescents under the age of 18 in Oslo, the capital of Norway, the number of violent crimes increased from 259 to 499 from 2013 to 2018, an increase of 93% in five years. (Link)
- Risk assessment is not intuitive. “There were fewer cars on the road last spring during the height of the pandemic, but traffic fatality rates increased 30% in the second quarter as evidence suggests drivers engaged in more risky behavior, federal officials say. A second NHTSA study of trauma centers found seriously injured or fatal crash victims took risks during the pandemic that included speeding, driving impaired, and not using their seat belts. For example, the study revealed a higher prevalence of alcohol, cannabinoids, and opioids in crash victims during the quarter compared to the months prior to the pandemic.” (link)
- “It is believed to be one of the largest COVID-19 outbreaks at any fitness centre in Canada. More than 50 cases, all identified within a single week, all connected to a small, niche spinning studio in downtown Hamilton.” (link)
- The machine consists of three parts. There’s a “head,” which houses automated surgical tools and brain-scanning cameras and sensors, against which a patient situates their skull. A device first removes a portion of skull to be put back into place post-op. Then, computer vision algorithms guide a needle containing 5-micron-thick bundles of wires and insulation 6 millimeters into the brain, avoiding blood vessels. (Neuralink says the machine is technically capable of drilling to arbitrary lengths.) The wires — which measure a quarter of the diameter of a human hair (4 to 6 μm) — link to a series of electrodes at different locations and depths. At maximum capacity, the machine can insert six threads containing 192 electrodes per minute. (link)
I have been researching the interactions between music (melody and rhythm) and our practice for years. You can find videos of these efforts starting from here:
Fast rhythm of music elevates heart rates and makes exercise easier (1).
Ran Levari, the AKBAN Berlin headmaster, researched beat patterns and their effects on training ease and coordination in a series of seminars and lessons.
- chimpanzee muscle exceeds human muscle in maximum dynamic force and power output by ∼1.35 times. This is primarily due to the chimpanzee’s higher fast-twitch fiber content, rather than exceptional maximum isometric force or maximum shortening velocities. (link)

- Oumuamua was the first object ever seen flying into our solar system and back out again. That’s opposed to most solar system objects that turn circles around the sun, never leaving the celestial neighborhood. (link)
Very interesting and original paper on the military capabilities of Israel against Sunni and Shiite hegemonies.
As a practitioner of the mainly symbolic discipline I do, it is a good reality check.
Here’s an excerpt,
The study assesses that a Sunni military threat, either with or without Turkey, could rapidly and unexpectedly emerge. The current combined military capability of the Sunni states is relatively limited compared to that of Israel, but over the long term, Israel would likely prove unable to maintain the decisive technological superiority it now possesses versus the current Sunni militaries. In such a scenario, Israel’s current exaggerated emphasis on combat with non-state light infantry, located within urban areas, under counter-insurgency rules of engagement would combine to compromise its long-term ability to cope with a Sunni conventional combined arms threat that could arise in the future.
