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.

Just as Netflix uses an algorithm to recommend movies we ought to see, their system suggests how to use computing resources at data centers more efficiently.
We hear a lot about the future of computing in the cloud but not much about the efficiency of data centers, those facilities where clusters of server computers work together to host applications ranging from social networks to big data analytics.

He becomes the 110th member of the Stanford Engineering faculty to join this prestigious academy.
Stephen P. Boyd, Samsung Professor of Engineering at the Stanford University School of Engineering, has been elected to membership in the National Academy of Engineering (NAE).
According to the NAE, membership honors outstanding contributions to "engineering research, practice or education" and to the "pioneering of new and developing fields of technology," among other acts of professional distinction.

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?

Computer scientist Pat Hanrahan shares this latest honor with two of his former students who now work for Google; the trio created tools for making computer-generated films such as “Avatar” and “Monsters University” more realistic.
Stanford Engineering Professor Pat Hanrahan will receive his third technical Oscar award for work that allows Hollywood to more easily and accurately reproduce real-world lighting in computer-generated films like “Avatar” and “Monsters University.”

By making digital versions of real-world science experiments available to anyone on the Internet, Stanford Professor Lambertus Hesselink has developed a new approach to integrating laboratory experience with massive online science courses.
For the past three years, two of Lambertus Hesselink's graduate students have been planning, building and calibrating a nano-conveyor belt. The one-of-a-kind experiment is about the size of a billiard table, and consists of lasers, mirrors, microscopes and computers that form a set of optical tweezers that can manipulate individual nanoparticles.

Just as flash memory once replaced hard disk drives to make smart phones possible, this new RRAM chip could lead to even smaller, smarter gizmos as well as new types of electronic devices that simply aren’t possible today.
In an engineering first, Stanford researchers have built a working prototype for a new type of memory chip that has the potential to store more data, using less space, than the flash memory chips found in smart phones, tablets and laptops today.
