    BLOCK

    In 2017, California replaced a fish-blocking road crossing on Upper Green Valley Creek; surveys later found 136 young steelhead upstream of the former barrier

    In 2017, engineers undertook a significant project to replace an old culvert that hindered fish migration in Upper Green Valley Creek. The successful replacement is evidenced by the discovery of 136 young steelhead fish in previously unreachable habitats. Researchers are actively studying the long-term effects on these fish populations and their growth.

    For 20 years, a road culvert blocked fish in California’s Sharber-Peckham Creek; crews replaced it in 2016, and 2017 monitoring found 740 juvenile coho upstream

    In Northern California, a four-foot metal pipe had hindered salmon migration for two decades. After its replacement, juvenile coho salmon gained access to essential spawning habitats. This case underscores the critical situation of culverts obstructing fish passage nationwide. Recent research has identified the need to evaluate these structures for effective prioritization in upgrades. Continuous investment, study, and conservation efforts are essential for sustaining fish habitats.

    Scientists gave mice an existing asthma drug before exposing them to peanut extract; 95% were protected from severe allergic reactions in the experiment

    Researchers at Northwestern University found that the asthma drug Zileuton reduces allergic reactions in mice fed peanut extract. The study indicates that Zileuton could block the inflammation that leads to anaphylaxis. While it works in mice, clinical trials in humans are just beginning. This research highlights a new biological pathway related to food allergies and the immune response.
