“The mathematics community is in turmoil as over 2,100 mathematicians from more than 75 countries have signed a petition calling for the relocation of the 2026 International Congress of Mathematicians (ICM) from Philadelphia, United States. Launched by University of Toronto mathematicians”

“… petition argues that the U.S. is no longer a safe or suitable host due to recent geopolitical tensions and domestic security issues.”

Sounds about right.

AI Use Appears to Have a “Boiling Frog” Effect on Human Cognition, New Study Warns

"In a new study, researchers claim to provide the first causal evidence that leaning on AI to assist with “reasoning-intensive” cognitive labor — mental tasks ranging from writing to studying to coding to simply brainstorming new ideas — can rapidly impair users’ intellectual ability and willingness to persist despite difficulty."

Dear Electrophysiologists.
I have recently started collaborating with a startup team of engineers that has developed an innovative MEA chip, supporting 40,000 simultaneous channels for recording and stimulation, all at USB 3.0 transfer rates.

Currently, we are in the phase of determining which product configurations to prioritize. Your insights would be invaluable in this process.
-What form factor would be ideal for your use case?
For instance, we can create:
1. 40K sites on a single well, allowing recording of all 40K. 12mm by 12mm sensing area with 70um pitch.
2. 125K sites on a single well, with recording of 40K. 5.2mm by 5.2mm sensing area with 15um pitch.
3. A high-throughput 6 / 24 / 96 well plate with any choice of either of the above wells.
4. A pay as you go product - Need not pay the full price for all the channels. Purchase at a discounted price with lower channel count and then unlock full channel access later, when more funds are available.

- What are the biggest limitations you have faced with current multi-electrode arrays (MEAs)?
What measurements do you believe labs would want to conduct that are currently unattainable?
- Would a 3D geometry of the array be beneficial, where each set of sites is positioned at different depth planes to record within thick slices organoids?
- What density-pitch?

If you are working with MEAs, I would appreciate hearing your thoughts on these questions. please comment here or in DM

Open or Blocked Skies? Community Moderation Practices in Bluesky

Sokoto, S., Badhuf, L., Ascigil, O. , Tyson, G., Castro, I., Scheuermann, B., Baronchelli, A. & Krol, M. (2026). Open or Blocked Skies? Community Moderation Practices in Bluesky. Paper presented at the ACM The Web Conference, 13-17 Apr 2026, Dubai, United Arab Emirates.
doi: 10.1145/3774904.3792106

Abstract

Content moderation is a major challenge for online platforms. While user-driven blocking is a common tool, its dynamics are usually hidden as moderation data is private. Bluesky makes moderation actions public-by-design, providing an unprecedented opportunity to study a community-driven moderation ecosystem at scale. ...

Across the Caribbean and Latin America, something extraordinary and shameful is unfolding.

On Friday the Cuban foreign minister Bruno Rodríguez accused the US of “extorting” countries
by forcing them to cancel decades-old deals with Havana for the supply of doctors

Cuban doctors, emissaries of one of the world’s most besieged nations, are being expelled from host nations,
contracts terminated,
health programmes dismantled.

And, in their absence, the poorest will pay
– in untreated illnesses, unattended births, undiagnosed cancers.
The region is, in effect, amputating its own lifeline
– under pressure from the US.
