A global screen for magnetically induced neuronal activity in the pigeon brain How animals detect the Earth’s magnetic field remains a mystery in sensory biology. Despite extensive behavioral evidence, the neural circuitry and molecular mechanisms responsible for magnetic sensin...

Scientists around former IMP group leader David Keays (@lmumuenchen.bsky.social show that #pigeons detect magnetic fields through their inner ear. Their discovery was now published in the journal @science.org: www.science.org/doi/10.1126/...

You are not wrong that it is true that if z(ab)=z(a)z(b) is true in binary, your condition will hold in any base - there are just occasional examples where it doesn't hold in the other direction.

Thanks, that looks interesting, though I am not sure if they are equivalent. E.g. 100010010 and 10010001 do not meet the condition of Z being multiplicative in binary, but do meet the condition of your problem in base 3 (product has only ones and zeros. (examples in base 10 might be very long)

I don't know if there is a simpler answer.

If every number in this set is unique (for your case 3,5,6,8,10,11}) the sum will only have zeros and ones. If any number is repeated, you will usually have a digit >1. However there will be some exceptions if the number of repeats is 0 or 1 MOD n, where n is your base.

OK. Well, in that case, I would offer this imperfect answer. Replace the two numbers you have with sets representing the positions of the ones. For your example 11010*100001 this would be {2,4,5} and {1,6}. Consider all the numbers you get from adding pairs of numbers taken from the two sets.

I am interested to see your answer! I can't think of a rule that deals in a simple way with carried digits.

Does your answer depend on the base being ten, or does it apply for any base >2?

🎉 Excited to share our new preprint presenting a complete de novo assembly of the zebrafish genome; a major advance for zebrafish genomics and research! 🧬

Simons Foundation Announces Fourth Class of Pivot Fellows The Simons Foundation is pleased to announce the fourth class of its Pivot Fellowship.

I’m honored to be named a 2025 @simonsfoundation.org Pivot Fellow! This support will allow me to build expertise in dynamical systems and control theory with mentorship from Guillaume Hennequin (@GJEHennequin on X).

🧠In this essay Carlos Ribeiro and Albino J. Oliveira-Maia, @champalimaudf.bsky.social, explore the brain-body interactions.

🤝Their collaboration bridges fundamental and clinical science, reminding us that progress comes from a joint effort between the two.

🚨Big news!🚨
The lab is relocating to Lisbon, joining a great team of experimental and theoretical neuroscientists, and the Neurotechnology Warehouse, a new initiative to bridge basic and translational research.

I'll be sharing postdoc openings soon. Come join us in this new incarnation of the lab!

The effect of time of day on exam pass rate in this study is quite dramatic. Consider that Edexcel runs some UK international exams as early as 7:30 a.m., which is even outside the range plotted in this study!

Thank you!

Thank you!

Does anyone have recommendations for neuroscience books or other non-fiction available on Audible? I enjoyed listening to Elusive Cures (read by the author @nicolecrust.bsky.social) and Innate (from @wiringthebrain.bsky.social), and I was wondering what other good audiobooks are out there?

I don't really understand why a table of contributions is bad. It seems like a straightforward way to give credit to people whose work contributed to the paper in different ways.

Greatly deserved! Congratulations!

Unforgettable trip to Lisbon! Packed with amazing food, wine, science, art, sightseeing, and a healthy dose of exercise! Huge thanks to my hosts @ribeirocarlitos.bsky.social at Champalimaud and Razmik Panossian at the Gulbenkian Foundation for the warm welcome.
