From bilingual workshops to comics and podcasts, scientists from marginalized communities are redefining science communication as relationship-building, not just information sharing. buff.ly/nDa1EtR #STEM 🧪

Science is best communicated through identity and culture – how researchers are ensuring STEM serves their communities

Scientists have traditionally focused on educating the public on science or correcting misinformation. But researchers from marginalized communities often have broader goals in science communication.

Elephant seal dive #behavior responds consistently to changes in foraging success regardless of sex or ocean habitat @peerj.bsky.social

Elephant seal dive #behavior responds consistently to changes in foraging success regardless of sex or ocean habitat

Understanding how air-breathing diving animals moderate their dive behaviour when foraging successfully is foundational in the study of their foraging ecology. Yet, this fundamental relationship remains unresolved with previous research pointing to inconsistent relationships, differing nominally according to sex, habitat type and scale. Empirically testing the relationships between dive effort responses and foraging success is further hampered because of challenges obtaining concurrent measures of behavioural responses and foraging success at sea. We compiled a multi-decadal dive dataset from 609 southern elephant seals, including their dive responses (transit rate, and relative dive and surface recovery duration) and buoyancy—changes in which provide an indirect measure of body condition change and foraging success. Using this dataset, we tested how seal dive behaviour alters when foraging remotely at sea. We found that as foraging success increased, seals increased transit (ascent, descent) rates and decreased relative dive durations for a given depth, with no response in surface recovery. Our results were consistent across sexes and foraging habitats, and account for the general effects of buoyancy on dive behaviour. The homogeneity of these findings suggests that there is a general functional response in which elephant seals perform, on average, shorter, steeper dives during periods of successful foraging. Importantly, we can align these results with predictions from the marginal value theorem (MVT), that a forager should remain in a patch only until gains drop below the neighbourhood mean. Our findings have broad-based implications for how ecologists interpret dive responses of wild marine animals, demonstrating the value of seeking independent in situ information on foraging success.

Federal scientists will stop updating the NOAA list of billion-dollar weather disasters. The list, which had grown rapidly in recent years, reflected both worsening extreme weather and expanding development nationwide.

Proud to be an Aussie (by choice) today! As a migrant 🇩🇪🇦🇺 dual citizen, it feels extra special to be contributing to Australian culture, science and the democratic progress in 2025. I knew these kind and inclusive people wouldn’t let me down. I choose this place as my home for a reason! 🇦🇺🐨🦘✊ #auspol

At this juncture I’d like to point out: * we’re on the brink of a golden age of medical healing * there’s enough money in the world to solve every problem in the world * a united approach could stop the climate crisis But a small group of sociopaths seeking personal power are going to throw it away.

I may be tired and a little hoarse, but as I said again and again on the Senate floor, this is a moment where we cannot afford to be silent, when we must speak up.
