One of the biggest dangers of AI in medicine?
Confusing “not assessed” with “normal.”
Missing data ≠ negative findings.
Unknown ≠ healthy.
Uncertainty ≠ zero.
We’re building RheumaNext around a simple principle:
AI should never turn missing clinical information into false certainty.
A fascinating insight into white blood cell biology and long-term health risks.
It may not be just the number of neutrophils-the most abundant type of white blood cell-that matters, but also their subtypes and biological activity.
Interestingly, differences in long-term health risks were observed even when neutrophil counts remained within the normal laboratory reference range.
Does the Mediterranean diet reduce inflammation independently of weight loss?
The Mediterranean diet improved lipid profiles even without significant weight loss. However, reductions in inflammatory markers were observed only during the phase when participants also lost weight, following the introduction of intermittent fasting.
Outside medicine, traveling with my kids gave me an idea:
What if every hotel could turn its surroundings into a little adventure?
I first built nature mini-quests for our own trips. Now it’s Natuqo 🌿
Scan a QR. Explore. No app or login.

I’m still impressed by how innovative @jack is. Always pushing the boundaries of what’s possible with AI.

Some Polish politicians seem more focused on internal power struggles and political games than on delivering meaningful reforms that would actually improve people’s lives.
To dla naszego środowiska bardzo trudne, ale - wobec znanych faktów - niestety nieuniknione. Zarząd @PL_2050 podjął decyzję o usunięciu z partii @Kpelczynska za „działanie na szkodę partii oraz wbrew uchwałom organów statutowych partii”.
This feels like a genuine turning point in human-AI interaction.
For the first time, we may be moving beyond AI that simply sounds human to AI that captures the natural rhythm of conversation - pauses, hesitations, self-corrections, subtle imperfections, and even those moments when someone seems to be searching for the right words.
The voice is still synthetic, but the experience is becoming remarkably human.
This could fundamentally change how we communicate with AI.
We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence.

Can regular brisk walking help protect against age-related macular degeneration (AMD)?
Higher levels of moderate-to-vigorous physical activity were associated with thicker outer retinal layers and 23% lower odds of AMD.
The most expensive copy-paste in healthcare? A patient’s story.
Patients repeat it. Doctors retype it. Again and again.
RheumaNext turns pre-visit intake into clinician-reviewed notes, backed by rule-based tools.
Less typing. More care.

its where AI in medicine aims
Important work from our team in @ScienceMagazine today, showing how our diagnostic orchestrator can reason through complex medical cases, achieving greater diagnostic accuracy while reducing testing costs.
A new injectable drug reduces visceral fat.
CBL-514 significantly reduced visceral fat volume compared with placebo (however, it remains unclear whether this translates into long-term health benefits; these findings come from phase 2 clinical trials).
Physical activity should be prescribed as part of the prevention and treatment of cardiovascular diseases.
The greatest health benefits can be achieved by going from complete inactivity to even a small amount of physical activity (you don't need to start with intense workouts or reach 10,000 steps a day).
