Lots of debate this week on whether journals should ban AI in peer review.
We actually tested this in our new preprint, and the results were pretty clear to me.
For context, I've reviewed for most of the big journals and evaluated 1,000 human reviews as an editor. I love to ce.
TLDR: From now on I won't do any peer review without AI. For clinical trials, I'd even call human-only review dangerous 🧵

Two physicists asked AI to choose a problem on its own, solve it and write a paper that could be published in a prestigious journal. In two hours, AI produced a paper with a novel, significant result.

What a beautiful video.
A mother and calf fell into a water tank. Both were rescued but during rescue the calf got separated from mother. Kurseong division staff brilliantly tracked the mother. It took 7 hours but they reunited them.
Reaction of mother in last !! Gods work.

I may have found two new Earth-sized planets in our galaxy this morning!
Inspired by yesterday's reddit thread on how someone used Claude Code to find a new planet, I spent this morning searching NASA TESS data on nearby stars that TESS scanned less thoroughly (at low cadence).
eline discovered two previously undocumented exoplanet candidates:
• TIC 370612437 (Cygnus constellation, 158 light-years): dims by 0.02% every 3.56 days → ~1.0× Earth's size.
• HIP 114417 (Andromeda constellation, 134 ly): 0.03% every 4.93 days → ~1.1× Earth.
The method to find them is to search for periodic dims in light coming from a star when a planet passes in front of it. For both the candidate exoplanets, the dip repeats 55 and 21 times respectively across 4 separate observing years (2019-2024).
These are obviously tentative and unconfirmed, but several signals point to them being credible candidates:
• same dip in NASA's and MIT's separate processing of the images
• hide one year's dip and predict its times from rest of the dips (matched in 3 of 4 years)
• flip light curves to create fake signals and validate observed dips against it
The method and results were reviewed by independent agents: Codex and fresh Claude. Important caveat: a faint neighbouring pair of eclipsing stars could fake the dip, so these exoplanets remain candidates pending further verification.
What's next: report to NASA's ExoFOP as Community TESS Objects of Interest, so astronomers can verify. The next scan of these stars via TESS will happen in Aug 2027 - Apr 2028, if the preregistered dip predictions hold up, these are indeed strong candidates.
Nicknames for these exoplanets: Aakanksha (Sanskrit: aspiration) and Orbit (well, Orbit)

An astrophysicist worked with Claude Science to create the first complete ultraviolet map of the sky. Astronomers have already created complete sky maps from radio to gamma rays. But large regions of the sky have never been observed in UV.
In today’s science blog, Brice Ménard explains how he guided Claude to find existing datasets, combine them, and fill in the gaps with statistical inference. The work would have taken humans weeks of work, but, with Claude, just took a few days while Ménard worked on other projects.
The resulting map is a useful teaching tool and an example of exactly the sort of slow, low-priority work which scientists never quite get around to, but which AI now makes feasible.

What is actually extraordinary is how the British nearly wiped out lions in India.
British viceroys, colonial officers, and visiting nobles turned lion hunting into a sport. A rite of passage. A photo opportunity. They organized grand hunting expeditions.
By 1884, a dozen lions remained in all of India, thanks to the Brits.
Nawab of Junagadh banned all lion hunting in his territory without special permission. He declared that anyone caught poaching a lion would face jail time and fines.
The British did not cooperate. The Nawab petitioned the colonial government to extend protections. They refused. British colonial officials saw lion hunting as their birthright.
After independence, the Indian Forest Department took over in 1965, designated Gir as a National Park and Wildlife Sanctuary, and built one of the most successful large predator conservation programs in the world.
Today there are 891 Asiatic lions in India. From 12 to 891.
So when The Economist expresses astonishment that a "poor country" can protect animals, perhaps they should ask who nearly exterminated them in the first place.

It is extraordinary that India, still a relatively poor country, can achieve something as selfless as protecting other creatures. We explain how it became remarkably good at animal conservation economist.com/asia/2026/10/0…

Look at the bottom of this image from 1914 depicting a divine scene from Mahabharata. In Marathi it says -
कर वसु पद बाविस ज्या वेद स्तन शोभती शिरें सात ।
पुच्छें पांच जयाला स्मरतां दे मुक्ति अल्प दिवसांत ॥

For decades, Kaziranga lost rhinos to men who knew the ground better than the rangers chasing them. Then someone changed the odds. In 2022, for the first time in 45 years, it went a full year without losing one. Read on.

Over two weeks the four lecturers between us, covered both frequentist and Bayesian methods. Ably assisted by our team of students and postdocs, who conducted extensive hands-on tutorial sessions. Astrostatistics is critical to modern astrophysics research!
A two-week course on Statistical Techniques in Astronomy was recently held at @IUCAApune, where Prof. Yogesh Wadadekar (@YWadadekar) delivered a series of lectures. Additionally, PhD students from #NCRA presented their research and conducted a tutorial session.
