SARS‑CoV‑2 (COVID-19)@covid19disease.bsky.social · 2d ago

🚨 BREAKTHROUGH: Mexican researcher Eva Ramón Gallegos achieved a milestone that puts Latin American science at the center of the world medical debate: she managed to completely eliminate the Human Papilloma Virus (HPV) in controlled clinical studies.

The voices of people—especially Black women—in marginalized communities are often systematically erased by white men. Attention-seeking AI guru Connor Leahy is now outlining an intellectual history of SV that is virtually identical to the one outlined by me and Gebru. 1/3

Our review "Advances, challenges, and opportunities for legged robots" is now out. We discuss technical challenges but also societal issues when deploying quadrupeds and humanoids in the real-world. Science Robotics: www.science.org/doi/abs/10.1... arXiv: arxiv.org/abs/2607.28952

Advances, challenges, and opportunities for legged robots

It is ill-gotten gains being used to exploit legal loopholes and subsume culture, all protected from public criticism by NDAs. This should not be legal, and it is a travesty that it is going unpunished. www.404media.co/ai-companies... /end

AI Companies Are Buying Tons of Old Books Because They're Free of AI Slop

ISBNdb, a company that sources printed books for AI companies to turn into training data, tells clients “the optics problem is real.”

The practice of AI companies secretly buying millions of old books (some vanishingly rare), scanning them for AI training, then destroying them, epitomises everything that is wrong with today's exploitative AI industry. 🧵 1/2

1. We—@eduede.bsky.social, @mjcrockett.bsky.social, Kevin Gross, and I—have a new preprint on the arXiv today, based on ideas that emerged during an @sfiscience.bsky.social workshop in November 2024: The unintended consequences of large language models as a labor-augmenting technology in science.

The unintended consequences of large language models as a labor-augmenting technology in science

As a labor-augmenting technology, large language models (LLMs) have the potential to accelerate scientific activity across the research pipeline. But even if LLMs perform on par with human experts at ...

No science fiction could have prepared us for just how stupid the end of the world can be. "The environment was on the brink of collapse, and so, rather than deal with that, we burned what fuel we had left getting computers to scam each other for money."

The fields are almost entirely split by gender on social media. It's quite creepy. If you know you know. And if you don't you'll say "but I saw men citing you" which isn't what I mean at all. 1/3

The names I bring up when discussing cognitive science and critical AI literacies with people IRL are all women, which I don’t think is a coincidence. These are the experts I recommend listening to about “AI”: @emilymbender.bsky.social @olivia.science @abeba.blacksky.app

My coauthor Jay Falk's postdoctoral fellowship was terminated by the Trump administration for documenting the hummingbird example in this paper.

FIGURE 2 Open in figure viewer PowerPoint Operational biological sex definitions applied to hummingbirds (Bleiweiss 1992; Bleiweiss 1999; Bleiweiss 2001; Diamant et al. 2021; Falk et al. 2022; Falk et al. 2021) where sex is operationally defined by binary plumage phenotypes in the field. Each row depicts a wild individual hummingbird with morphological traits (beak length, plumage coloration), behavioural traits (territoriality) and their unobserved gamete type. This example illustrates how the same individual can be operationally defined as one sex in the field (based on external phenotypes) but classified as a different sex based on their gametes (which cannot be easily observed in the field), highlighting how definitional choices shape scientific reporting of sex.

In our Viewpoint (onlinelibrary.wiley.com/doi/abs/10.1...) we synthesize the gametic definition (outlined by Janicke et al below) and other definitions of sex (e.g., multivariate definition). We contend that is NO consensus on “biological sex” (maybe a consensus isn’t actually necessary…)

UK waters hit with extreme heatwave as global sea temperatures reach record levels

UK waters hit with extreme heatwave as global sea temperatures reach record levels

Experts warn that some marine species are at risk of ‘mass mortality events’ in ever-warming oceans UK waters are being hit with an “extreme” marine heatwave, the Met Office has said, as scientists warn the high ocean temperatures globally could result in “mass-mortality events” for some species. The forecasters said these elevated temperatures have developed rapidly because of last month’s heat dome, during which most of Europe sweltered in its worst ever heatwave that scientists said would have been impossible without the climate crisis.

The rise of larger vehicles like SUVs and pickup trucks, with their taller hoods and larger blind zones, has contributed to a 75% increase in pedestrian and cyclist deaths since 2009. Until we design better streets and ban these vehicles, people outside these vehicles will keep dying.

The Deadly Rise of Giant Trucks and S.U.V.s (Gift Article)

The vehicles on American roads have grown larger — and they are killing thousands more pedestrians, a Times investigation found.
