As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 years - ever since he was a PhD student with Neil Shubin at the University of Chicago. A new study from Gillis and the MBL-UChicago Graduate Research Fellowship Program doesn’t quite put the matter to rest – but it gives important insight to a broader question in evolutionary biology.

With the arrival of spring a few weeks ago, new buds and colours on the trees started to appear.

Along with that new growth, a UBC Okanagan researcher has determined that some trees in spring also provide simple, visual clues—raised or lowered branches—to indicate that they are rehydrating or water-stressed.

The American Institute of Biological Sciences (AIBS) has published a report in the journal BioScience highlighting the winners of its 2025 Faces of Biology Photo Contest. The contest was cosponsored by AIBS and the Society for Integrative and Comparative Biology (SICB).

The study, published in Fish and Fisheries, analyzed global aquaculture production from 1950 to 2023 and found that, since the 1980s, the industry has shifted toward a smaller number of intensively farmed species—particularly finfish—that tend to have lower overall sustainability potential.

Computational biologists developed a simple way to test a language model’s understanding of proteins. The method holds potential to improve a range of language models in science.

Harvard researchers reveal the earliest known Chelicerata in a new study published in Nature. The 500-million-year-old fossil, named Megachelicerax cousteaui, provides unequivocal evidence of chelicera, a feature never before seen in Cambrian arthropods. The discovery pushes back the origin of chelicerates by at least 20 million years and proves their distinctive body plan emerged during the Cambrian explosion.

A review finds that antibiotic resistance genes—capable of undermining modern medicine—can travel through the air across both cities and farmland, and argues that airborne spread represents an overlooked public health risk.

At AACR 2026, Insilico will unveil four novel cancer inhibitors discovered via its end-to-end Pharma.AI platform. By harnessing trillions of data points and millions of molecular fragments, the platform integrates generative biology for target discovery with generative chemistry for de novo molecular design, accelerating the path from data to drug candidates.
