DNA origami suggests route to reusable, multifunctional biosensors
Using an approach called DNA origami, scientists at Caltech have developed a technique that could lead to cheaper, reusable biomarker sensors for quickly detecting proteins in bodily fluids, eliminating the need to send samples out to lab centers for testing.
“Our work provides a proof-of-concept showing a path to a single-step method that could be used to identify and measure nucleic acids and proteins,” says Paul Rothemund (BS ‘94), a visiting associate at Caltech in computing and mathematical sciences, and computation and neural systems.
A paper describing the work recently appeared in the journal Proceedings of the National Academy of Sciences. The lead authors of the paper are former Caltech postdoctoral scholar Byoung-jin Jeon and current graduate student Matteo M. Guareschi, who completed the work in Rothemund’s lab.
CARTA: Oxytocin’s Pathway to the Origins of Speech and Dance
Dr. Theofanopoulou studies neural circuits behind sensory-motor behaviors like speech and dance, aiming to develop drug-and arts-based therapies for brain disorders. Her brain imaging research reveals overlapping motor cortex regions controlling muscles for speech and dance, while transcriptomic studies show upregulation of the oxytocin gene pathway in key areas like the motor cortex and brainstem. Using zebra finches, Bengalese finches, white-rumped munias, and humans, she demonstrates oxytocin’s role in vocal production. She also developed genomic tools to apply these findings across vertebrates. Her future work explores oxytocin-based drugs and dance therapies to treat speech and motor deficits in brain disorders.

What’s the future of connecting our tech to our brains?
A brain’s 86 billion neurons are always chattering along with tiny electrical and chemical signals. But how can we get inside the brain to study the fine details? Can we eavesdrop on cells using other cells? What is the future of communication between brains? Join Eagleman with special guest Max Hodak, founder of Science Corp, a company pioneering stunning new methods in brain computer interfaces.
Smart Bullets: When Hiding May Not Be Enough
Smart bullets are real—and they might already be in use. From DARPA’s EXACTO to Russia’s secretive programs, guided bullets have come a long way since The Fifth Element. Here’s what we know.

How to Make Superbabies
Working in the field of genetics is a bizarre experience. No one seems to be interested in the most interesting applications of their research.
We’ve spent the better part of the last two decades unravelling exactly how the human genome works and which specific letter changes in our DNA affect things like diabetes risk or college graduation rates. Our knowledge has advanced to the point where, if we had a safe and reliable means of modifying genes in embryos, we could literally create superbabies. Children that would live multiple decades longer than their non-engineered peers, have the raw intellectual horsepower to do Nobel prize worthy scientific research, and very rarely suffer from depression or other mental health disorders.
The scientific establishment, however, seems to not have gotten the memo. If you suggest we engineer the genes of future generations to make their lives better, they will often make some frightened noises, mention “ethical issues” without ever clarifying what they mean, or abruptly change the subject. It’s as if humanity invented electricity and decided the only interesting thing to do with it was make washing machines.
Turning Off Nerve Signals: Scientists Develop Promising New Pancreatic Cancer Treatment
Pancreatic cancer is closely linked to the nervous system, according to researchers from the German Cancer Research Center (DKFZ) and the Heidelberg Institute for Stem Cell Technology and Experimental Medicine (HI-STEM). Their recent study, published in Nature, reveals that pancreatic tumors actively reprogram neurons to support their growth.

Scientists Grow Mini Brains in the Laboratory! | Brain organoids
This episode is all about brain organoids. Cerebral organoids or brain organoids were developed in 2013 by Madeline Lancaster and Jürgen Knoblich. Brain organoids are also called mini-brains and they are a powerful tool to grow brain-like structures in petri dishes. Brain organoids enable studies on the development of brains, brain diseases or brain infections. In this video, we will talk how we can make brain organoids and how we use brain organoids.

Okay, so what are brain organoids? Brain organoids or cerebral organoids are laboratory-grown structures which mimic parts of the brain. Brain organoids establish regions with multiple layers of neurons comparable to the developing brain. However, cells within brain organoids are less specific compared to cells we find in the brain. We also do not find any specific \.
