🔬 Revolutionary Breakthrough: 3D Printing Inside the Body Without Surgery!

 

A team at Caltech has developed ultrasound-guided 3D printing—a game-changing technique that could fabricate medical implants inside the body and deliver personalized therapies to deep tissues—all without invasive surgery!

💡 How It Works:
The DISP (Deep Tissue In Vivo Sound Printing) platform uses:
✔ Low-temperature–sensitive liposomes (LTSLs) to carry cross-linking agents
✔ Focused ultrasound to trigger precise, controlled biomaterial formation
✔ Real-time imaging for accuracy

🐭 Proof of Concept:
✅ Printed drug-loaded biomaterials in mouse bladders
✅ Engineered functional tissues deep in rabbit muscles
✅ No tissue damage—unpolymerized ink cleared safely in a week

🌟 Why It Matters:
➡️ Enables minimally invasive treatments
➡️ Customizable for drug delivery, tissue repair & bioelectronics
➡️ Overcomes limits of traditional light-based bioprinting

🚀 Future Potential:
"DISP unlocks applications in bioelectronics, regenerative medicine & targeted therapy—all inside the living body!" — Wei Gao, PhD, Senior Author

👉 "Imagine printing a healing scaffold exactly where it's needed—no scalpels required!"

🔬 Egg-Laying Mystery Solved: The Gene That Makes Platypuses & Echidnas Unique! 🦆🐾

For decades, scientists knew   Australia’s egg-laying mammals—platypuses & echidnas—defy mammalian norms   in sex determination. Now, we’ve cracked their genetic secret! 🧬 The Breakthrough: A new study in  Genome Biology  reveals that  a single gene (AMHY) —more like those in fish & amphibians—controls sex in monotremes, not the usual  SRY gene  found in other mammals. 🐣 Why It’s Wild: Monotremes split from other mammals  175 million years ago , evolving a  reptile-like  sex chromosome system (multiple X/Y pairs). AMHY , a hormone gene on their Y chromosome, triggers male development— a first for mammals! 🔎 How We Found It: Decoding platypus & echidna genomes  revealed AMHY’s role in testis formation. Unlike typical sex genes (which act on DNA),  AMHY works like a hormone , signaling cells directly—similar to some fish! 🌍 What’s Next? Researchers are now studying  how AMHX & AMHY evolved differently ...

Can AI Understand Literature? Columbia Researchers Put It to the Test

Image
 Despite significant advances in large language models (LLMs) such as ChatGPT—particularly in assisting with thinking, research, summarization, and the comprehension of complex technical texts—their ability to interpret storytelling and literature remains an open question. Issues related to interpretive nuance and depth continue to persist. Researchers at Columbia Engineering have addressed these challenges through a novel and ethically grounded evaluation framework. Their work received the Best Paper Award (2025) at Transactions of the Association for Computational Linguistics (TACL) , highlighting its methodological rigor and contribution to the field. “Before we can place real trust in LLMs’ analytical abilities, we need careful evidence of what they can and cannot do,” stated Kathleen McKeown, the Henry and Gertrude Rothschild Professor of Computer Science at Columbia Engineering. The research was led by Professor McKeown and Associate Professor Lydia Chilton. “If LLMs are to ...
