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.

Stanford researchers have developed a tiny moving probe to study the mechanical properties of sensory cells in the ear. Their work could lead to new treatments for hearing loss, and the probe may advance other scientists’ research as well.
Much of what is known about sensory touch and hearing cells is based on indirect observation. Scientists know that these exceptionally tiny cells are sensitive to changes in force and pressure. But to truly understand how they function, scientists must be able to manipulate them directly. Now, Stanford scientists are developing a set of tools that are small enough to stimulate an individual nerve or group of nerves but also fast and flexible enough to mimic a realistic range of forces.

Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between three desired characteristics: strength, flexibility and the ability to dissipate heat.
When engineers design devices, they must often join together two materials that expand and contract at different rates as temperatures change. Such thermal differences can cause problems if, for instance, a semiconductor chip is plugged into a socket that can’t expand and contract rapidly enough to maintain an unbroken contact over time.
