These fully grown sea lions won't stop nursing, and scientists don’t know why | CBC Radio A new study documents the surprising prevalence of 'supersuckling' among Galápagos Islands sea lions.

To rule out nutrient scarcity as a cause, Andrew Trites says you’d need to look not only at quantity of food, but also quality. Steller #sealions have experienced population declines when their diets consisted mainly of lower-fat #fish. www.cbc.ca/radio/asitha... @ubcmarinemammal

Drop in ocean's iron spells danger for seals, penguins, and whales - Oceanographic Global warming is impacting ocean circulation and photosynthesis in phytoplankton, shrinking food supplies for krill, whales, and seals.

Climate-driven changes to distribution of micronutrients across global ocean may reduce iron delivery to marine habitats, weakening the base of marine food chains. Crucially, over time this could mean fewer #krill and fewer #whales, #seals, and #penguins. oceanographicmagazine.com/news/drop-in...

The NIH has lost its scientific integrity. So we left “We can no longer lend our credibility to an organization that has lost its integrity,” write four scientists and administrators who recently resigned from the NIH.

This is so incredibly heart-breaking. To Jay Bhattacharya and Matthew Memoli at NIH--you have betrayed the entire scientific community. Deeply committed staff are leaving in droves--because you are destroying the institution. Shame on you. www.statnews.com/2026/01/10/n...

Scoop: FDA vaccine chief’s memo cited 10 pediatric Covid-19 vaccine deaths—but the agency’s own analysis found 0–7. Dr. Vinay Prasad circulated a memo before FDA scientists finished their work. His conclusions overshot what the agency’s own analysts ultimately found.

Prasad, Makary and others who claim that COVID19 vaccines killed 10 children are not telling the truth.

According to @jeremyfaust.bsky.social, the committee that worked on this question reported that there were ZERO deaths that they were certain were caused by the vaccines.

Well worth reading.

Orcas and dolphins caught on video by researchers collaborating to forage, hunt salmon | CBC News Researchers from Dalhousie University were trying to study how northern resident orcas find salmon to eat, but they ended up finding an unexpected symbiosis with another species — dolphins.

“They were sort of spread out and pinging through the water in a much broader area than what the whales can search — and the whale was listening.”

I really hate it when scientists keep saying that “we need to rebuild trust in science,” because it implies that scientists are to blame for the mistrust rather than the millions of dollars of dark money that have funded political attacks on science in order to advance a far right agenda.
