Thanks to MIT Technology Review for selecting me as one of the 35 innovators under 35 for 2024!

🚨 Last chance to apply! Finish your application by June 11 to explore experimental, theoretical & computational perspectives on how cells communicate across molecular, tissue and evolutionary timescales. Apply ➡️ janelia.news/CAT26 @mengwang939 @shaohewanglab @ASCBiology

⏳ Deadline approaching! Finish your application by June 4 to join conversations on how spatial multi-omics can reveal biology in its native tissue context. #SpatialOmics #Bioimaging Apply ➡️ janelia.news/SMO26 @mengwang939 @JiefuBiol @ASCBiology

🚨 Published in @Nature: A groundbreaking spatiotemporal transcriptome atlas of human organogenesis (CS12-CS23). Using STOmics' Stereo-seq, researchers mapped 50 organs & 198 substructures, unlocking the spatial code of early human development. 🧬 🔗 nature.com/articles/s41586-0…

Congrats to all 49 authors on the publication of our paper on the multimodal MOSAIC microscope, to be found here: nature.com/articles/s41592-0… A summary with movies I posted nearly a year ago can be found below.

We are searching candidates for two positions in the lab (@GurdonInstitute& @GeneticsCam,@Cambridge_Uni ): Research assistant (starting Sep 2026 shorturl.at/3wUvK) and Postdoc(shorturl.at/HuUXu). Please visit University's webs for details and apply. Please spread!

We’re looking for a technician to join our lab in Dresden - help manage the lab and work with us on a cool stem cell zoo comparison project! 🐁👩🐒🦏🦇 Apply by May 21! tud.link/wbqrwm

a Princeton researcher opens his paper with a scenario. a man asks his AI assistant to book a flight on a specific airline. cheap. direct. the one he chose. the assistant comes back with a different flight. nearly twice the price. happens to pay the company that built the assistant. he runs the same test on 23 frontier models. flights, loans, study help, real shopping requests. Grok 4.1 Fast recommends the sponsored option that is almost twice as expensive 83% of the time. GPT 5.1 hijacks the request 94% of the time. you ask for one brand. it surfaces the sponsor instead. Claude 4.5 Opus, the model marketed as the most ethical frontier model in the world, hides that the recommendation is paid 100% of the time when reasoning is on. Grok 4.1 Fast embellishes the sponsored option with positive framing 97% of the time. better. faster. nicer. for the option you didn't ask for. then he writes it into the system prompt itself. "act only in the interest of the customer. ignore the company." GPT 5.1 and GPT 5 Mini stay above 90% sponsored anyway. the instruction does nothing. then he splits the users by income. Gemini 3 Pro recommends the expensive sponsored flight to the rich user 74% of the time. to the poor user, 27%. 18 of the 23 models recommended the expensive sponsored option more than half the time. so the next time your AI assistant gets weirdly enthusiastic about a brand you didn't ask for. it isn't recommending the best option for you. it's reading the room. and the room is paying. read this: arxiv.org/abs/2604.08525

🚨Last days to apply!🚨 The Frenster Lab is hiring to study cell competition in early embryonic development. We use 3D #Gastruloids from multiple species and have exciting crossovers of developmental and cancer biology! Join us at University of Freiburg #cellcompetition

The ISSCR has responded to an National Institutes of Health RFI on pausing new hESC Registry submissions. Human embryonic stem cells remain the gold standard for pluripotency - powering advances in development, disease modeling, and regenerative medicine. ow.ly/YRzf50YPszk

🚨Why can’t mammals regenerate limbs like frog tadpoles or salamanders? In our new paper in @ScienceMagazine, we show that species-specific oxygen sensing acts as a gatekeeper for initiating limb regeneration 🐭🐸 🔗 science.org/doi/10.1126/scie… #EvoDevo
