For #PhycologyFriday, here’s a funky Bull Kelp bulb sent to me by a friend in Ucluelet. Anyone know what causes this to happen? Never seen one like this before

Ebikes are not just bikes with a motor and battery. They are a new form of transportation

Interesting study from Germany on e-bikes and the modes they replace:

"43.1% of electric bicycle trips and 63.2% of electric bicycle mileage would have been undertaken using a car if no e-bike had been available, highlighting their substantial potential to reduce transport-related CO2 emissions"

Hard as it is to feel hopeful abt international law as we watch states breaking it down to uphold Israel’s genocide in Palestine, it seems that even the cynical read is that this ruling could have substantive impacts. Nice to see petrostate govs like Canada’s take an L!

The BC government considered "fast-tracking" the northern BC mine where three miners are currently trapped underground. Premier David Eby listed the mine’s underground expansion under Bill 15, the province's controversial new law to override regulations because of Trump's tariff war.

Underground mine where workers trapped was on BC fast-track list

For this #PhycologyFriday I'm happy to share my ✨new paper✨ about #kelp disease -> rdcu.be/ets28

Pink-spot disease occurs in kelp nurseries across North America and Europe according to our survey and we identified a bacteria (Algicola sp.) as the likely causative agent.
