Coffee-driven deforestation is making it harder to grow coffee, watchdog group says In Brazil's coffee-producing areas, more than 42,000 square miles of forest have disappeared over about two decades, says Coffee Watch. Deforestation leads to drought, which harms crop yields.

Just gave this a spin on a paper I've been working on for too long and WOW. Even though it was outside its topic domains, the feedback it highlighted was oh so constructive and insightful. Highly recommended and congrats @odedrechavi.bsky.social and team on an awesome tool!

A comet, tail, and background stars

Comet C/2025 A6 Lemmon, 48.5 minutes of exposure across 97 images taken from Bear Divide in Los Angeles. This is the first time I’ve processed a comet observation like this so I had to do some quick learning and experimentation. Hopefully I’ll improve on this in the future.

Venera 4 entered the Venusian atmosphere on October 18, 1967, and became the first probe to transmit data from the atmosphere of another planet. The descent capsule reached an altitude of 27 kilometers above the planet's surface, where it succumbed to the atmospheric pressure and temperature.

AI-powered high-throughput digital colony picker platform for sorting microbial strains by multi-modal phenotypes - Nature Communications Phenotype-based screening is a major bottleneck in the development of microbial cell factories. Here the authors build an AI-powered digital colony picker for single-cell-resolved, contactless screening and export of microbial strains, which identified lactate-tolerant Zymomonas mobilis mutants.
