Stanford researchers develop a single-cell genomics technique to reverse engineer the developing lung
How do embryos form the cells in our lungs, muscles, nerves and other tissues? A new process decodes the genetic instructions that enable the all-purpose cells of the embryo to multiply and transform into the many specialized cell types in the body.
Consider the marvel of the embryo. It begins as a glob of identical cells that change shape and function as they multiply to become the cells of our lungs, muscles, nerves and all the other specialized tissues of the body.
Now, in a feat of reverse tissue engineering, Stanford researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform a myriad of different biological tasks.

Manu Prakash won a contest to develop the 21st-century chemistry set. His version, based on a toy music box, is small, robust, programmable and costs $5. It can inspire young scientists and also address developing-world problems such as water quality and health.
When Manu Prakash was young he had a thing about flames. He's not encouraging all kids to follow his fiery lead – he did burn one hand pretty badly – but he thinks kids should explore more when it comes to learning about science. That's the idea behind his programmable, toy-like device that won a competition to "reimagine the chemistry set for the 21st century."

Groundbreaking study finds hundreds of variants of neurexin proteins, offering new evidence linking these differences to complex brain functions and disorders like autism.
Neuroscientists and bioengineers at Stanford are working together to solve a mystery: How does nature construct the different types of synapses that connect neurons – the brain cells that monitor nerve impulses, control muscles and form thoughts.

When humans go into space, the reduced gravity can weaken the heart's ability to pump hard in response to a crisis. Stanford student researchers are developing a simple device to monitor an astronaut's heart function, and have flown in near-zero gravity to show that it works.
The human heart was not meant to pump in space.
Early astronauts in the Apollo program performed every conceivable physical test to ensure that they were each at the pinnacle of human fitness. And yet, when they returned to Earth after just a few days in space, they felt dizzy when standing and tests showed that each beat of their heart pumped less blood than it had before the mission.

Shedding a light on pain: A technique developed by Stanford bioengineers could lead to new treatments
Stanford researchers have developed mice whose sensitivity to pain can be dialed up or down by shining light on their paws. The research could help scientists understand and eventually treat chronic pain in humans.
The mice in Scott Delp's lab, unlike their human counterparts, can get pain relief from the glow of a yellow light.

Our brains have billions of neurons grouped into different regions. These regions often work alone but sometimes must join forces. How do regions communicate selectively?
Stanford researchers may have solved a riddle about the inner workings of the brain, which consists of billions of neurons, organized into many different regions, with each region primarily responsible for different tasks.

Recording the neural activity of monkeys as they plan to reach, or just react, will help engineers design better brain-controlled prosthetic limbs.
Ready, set, go.
Sometimes that’s how our brains work. When we anticipate a physical act, such as reaching for the keys we noticed on the table, the neurons that control the task adopt a state of readiness, like sprinters bent into a crouch.
Other times, however, our neurons must simply react, such as if someone were to toss us the keys without gesturing first, to prepare us to catch.
How do the neurons in the brain control planned versus unplanned arm movements?
