Over 5 years of writing code, collating metadata, processing, QCing, reprocessing, QCing, reprocessing… not to mention the weeks, months, & years of field work by a small army of researchers. I am SO excited that we’re sharing this incredible dataset. 👉 nature.com/articles/s41597-0…

We are Americans.
We are the most powerful nation on the planet.
What defines us is not our power to dominate the weak.
What demonstrates our character is not our capacity to traumatize the afflicted.
What speaks our truth is not how we taunt, deride or belittle the embattled, broken or battered.
We are:
The country of the Marshall Plan
The nation of The Berlin Airlift
The nation whose leader said, “Mr. Gorbachev, tear down this wall.”
We are at our best when we are resolute against evil -- not when we kowtow to those who perpetrate it.
We tell our truth when we defend the weak -- not when we do it only if we get protection money.
We are America when our leaders call the dictators dictators and those who fight to defend democracy against tyranny what they are: heroes.
Donald Trump and JD Vance didn't show strength today -- they showed weakness.
They belittled a giant and showed just how small they are.
They have the most vaunted titles in the world: President and Vice President of The United States of America. But the title doesn't make the man. And today both men brought shame to their titles.
A weary warrior was before them. A beleaguered man who has lost thousands of his friends and comrades to the unjust and illegal aggression of an authoritarian leader.
They showed no grace; no magnanimity of spirit; no diplomatic acumen. They were small bullies with big titles and they disrespected the history and legacy of the nation they lead.
Today, Donald Trump acted more like Russia's Putin than America's President.

As an Elon Musk biographer, I would peg his IQ as between 100 and 110. There’s zero evidence in his biography of anything higher.
And I want to repeat that now, lest you think it a typo.
There’s zero evidence, from his life history, of Musk having anything higher than a 110 IQ.

Excited to share our new paper on Key Biodiversity Areas in the Southern Ocean, led by Sarah Becker and @cassandrafish.

We are calling on Australia’s governments to urgently and collaboratively ramp up preparations for bird flu in wildlife, as new research led by @ucdavis provides the first strong evidence of mammal-to-mammal transmission of the deadly H5N1 strain.
Biodiversity Councillor Professor John Woinarski said: "Australia has been lucky to date, but we can’t presume this will continue. I fear the impact on many of our native animal species. Some species may not survive such rapid and dramatic losses."

Check out our new paper in @conphysjournal where we show variation in three reproductive steroid hormones in female humpback whales and show evidence consistent with a temporal window in which this population experiences higher rates of estrous initiation! doi.org/10.1093/conphys/coae…

Increíblemente honrada que mi trabajo sea destacado en la prensa nacional. Los fósiles son claves para el entendimiento del pasado de nuestro territorio🦭

This nuanced review of neuroscience research from lab to field, discusses the value of research in the wild AnD controlled lab experiments- it’s about finding the right setting for your question. Thank you @neuroetho for your kind words about our study.

SMRU are excited to share an infographic by @mrjboc highlighting the current status of UK seal populations and our work on the Special Committee on Seals.

Thank you @ScienceMagazine @NewsfromScience for telling our story. Antarctic science is more important than ever in today's changing world. We just feel 'gutted' by this huge loss. science.org/content/article/…

Small videocameras attached in
Humboldt penguins (HP) show us unreleased images of their prey capture behavior during their dives.
These images show how HP raised the #anchoveta shoal close to the surface to ⬆️ their catch rate. Poster and video ⬇️ youtu.be/DT0pHyy1TJg?feature…

Thanks to @NafeesaSyeed and @latimesopinion for an opportunity to share climate science beyond the scientific community!
We need forward-looking information on how species will be impacted by the marine heatwaves we're currently experiencing. -> rb.gy/tf2v9

Welch et al. examine the effect of four marine heatwaves in the Northeast Pacific on the distributions of 14 top predators, revealing highly-predictable predator responses both among and within heatwaves.

Our new paper in @NatureComms uses a multi-species, multi-heatwave framework to model MHW impacts on marine predators.
We find a surprising diversity of impacts across species and MHWs, signaling a need for ecosystem-based investigations of MHW impacts.

This is the face of an oceanographer that maps the #Antarctic continental shelf. Seals with sensors are rewriting previous estimates of the ocean depths. In the most extreme case “they were diving 1,000m deeper than what we thought was the ocean floor.”
