The AI Shift: Why are there still so many radiologists? AI diagnostic tools are being used by healthcare providers yet demand for skilled human specialists is growing

“(…) I think the story of radiologists should be a reminder to technologists not to make sweeping assertions about the future of professions they don’t intimately understand. If we had indeed stopped training radiologists in 2016, we’d be in a real mess today.”

Maths in a minute: Correlation versus causation Wet cats don't cause umbrellas and umbrellas don't cause wet cats.

It's been raining outside and the cat came home wet. People are also carrying umbrellas. Which reminds us that #correlation isn't #causation plus.maths.org/content/math... #maths #mathematics #statistics

Dass wir einen anti-feministischen Backlash erleben, ist leider auch die Schuld falsch verstandener Wissenschaft. Als "evolutionäre Psychologie" werden uns seit Jahren Geschlechter-Stereotype als evolutionär entstandene Fakten angedreht. Das ist gefährlich. (Thread)

Kinda weird that experts on AI tend to be cautious and divided about potential applications, sustainability issues and regulatory requirements of this tech, while the most incompetent boneheads you'll ever meet are all very excited about it.

Eh, prob doesn't mean anything.

A promotional graphic for Her Maths Story featuring the documentary “Counted Out” by Vicki Abeles. The top section shows the HMS logo and a banner image with a crowd of people behind the film title “COUNT≠D OUT” in large red letters, alongside the tagline “Math is power.” Several film festival laurels appear along the bottom of the banner. Below, text reads: “Reflecting on ‘Counted Out’: A Conversation About Maths, Power, and Inclusion — By the Her Maths Story Team.”

In our latest blog post, we reflect on our #CountedOut screening event in mid-October and summarise the core action points we identified in the post-film discussion.

Share YOUR ideas on how you can take action personally to make the maths table more inclusive.

Figure 1: The important dimensions of CAILs across research and education; clockwise from 12 o’clock: Con-
ceptual Clarity is the idea that terms should refer. Critical Thinking is deep engagement with the relationships
between statements about the world. Decoloniality is the process of de-centring and addressing dominant
harmful views and practices. Respecting Expertise is the epistemic compact between professionals and society.
Slow Science is a disposition towards preferring psychologically, techno-socially, and epistemically healthy
practices. The lines between dimensions represent how they are interwoven both directly and indirectly.

What makes COVID different?
• It can breach the blood–brain barrier
• It can damage your endothelial lining and increase clot risk
• It can persist in tissues
• It can lower key immune cells
• It may increase cancer risk
• You can catch it multiple times per year
These are not “normal cold virus” behaviors.’

Long COVID is caused by SARS-CoV-2.
Persistent symptoms come from real, documented damage. Not anxiety, not imagination, not “just needing rest.” Hundreds of thousands of studies show SARS-CoV-2 affects the body in ways we’re still uncovering.
Just because you’ve had multiple infections and “felt fine” doesn’t mean it will stay that way.’

• Improve air quality (filters, ventilation)
• Wear a high-filtration mask in shared indoor air
• Test when exposed or symptomatic
• Stay home when sick
• Use layered protections with friends, family, and workplaces

COVID isn’t acting like the viruses most of us grew up with, and treating it like “just a cold” is putting people at real risk. David Brasure breaks down why SARS-CoV-2 is fundamentally different, how it causes long-term damage, and what we can do to protect ourselves.

The image shows a dark blue background with the Her Maths Story logo at the top. At the centre of the image, we have a rectangular graphic with light grey background, inside a rounded sage green rectangle, large dark-green text reads ‘What Can You Do?’ Beneath this, smaller text says: ‘A practical guide for those wishing to improve gender diversity in mathematical research.’ The top left shows the Piscopia Initiative and How to Train Your Allies logos. At the bottom corners are two cartoon-style characters: on the left, a light-skinned woman with long, curly, golden-brown hair, resting her chin on her hand and looking upward; on the right, a woman with medium-brown skin wearing a red hijab, also resting her chin on her hand and looking upward thoughtfully. Below the rectangular graphic, small text says: ‘by Rosie Evans & Ashleigh Ratcliffe’.
