Nintendo has posted a call for participants for another Playtest Program, and this time, it's looking for 40,000 testers and not just 10,000 like in the first one. If you'll recall, Nintendo looked for 10,000 participants for the first Playtest event last year to test an unnamed, mysterious Switch Online feature.

Written by: Jesse Jenkins Published: A first-of-its-kind study traces the rise of ant- and termite-eaters, revealing how mammals returned to the evolutionary table — at least a dozen times — to hone traits for feasting on the social insect bonanza that exploded after the extinction of the dinosaurs.

Five companies now control over 90% of the restaurant food delivery market

While reading the latest results from Prosus, I realized there seems to be a trend that nobody is talking about. There is an obvious wave of consolidation in the food delivery market happening right before our eyes. The once-hot food delivery sector has gone cold faster than your DoorDash order. New entrants have disappeared as most of the VC money chases the cool and hip AI startups. Alongside a wave of acquisitions, the world's food delivery market is consolidating in the hands of 5 companies.

'Sticky thinking' hampers decisions in depression

Though low mood is the best-known symptom of depression, indecisiveness and biased thinking are also common. But these problems, which can lead to delays in making important choices — and being more likely to make poor ones — receive less attention, write the authors of a recent paper in Emotion. Many of the theories that have been put forward to explain difficulties with decision-making are based on work suggesting that depressed people are not as responsive to rewards, or punishments, as thos

However, an increasing number of studies continue to show that gaming poses no significant threat to society or human health, and the latest adds an interesting new perspective to the ongoing debate.

The new variant is dubbed NB.1.8.1. Like all the other currently circulating variants, it's a descendant of omicron. Specifically, NB.1.8.1 is derived
