Supercomputers use graphics processors to solve longstanding turbulence question
Supercomputers use graphics processors to solve longstanding turbulence question
Advanced simulations have solved a problem in turbulent fluid flow that could lead to more efficient turbines and engines. When a fluid, such as water or air, flows fast enough, it will experience turbulence - seemingly random changes in velocity and pressure within the fluid. From my first days studying fluid mechanics I had some fundamental questions that I wanted to know the answers to.

Steering wind power in a new direction
Four of the turbines on a TransAlta Renewables wind farm in Alberta, Canada, that were used for the wake-steering experiment. The truck in the lower left corner of the photo gives a sense of the wind turbines' size. (Image credit: Calgary Drone Photography) On a working wind farm, Stanford researchers have shown that angling turbines slightly away from the wind can boost energy produced overall and even out the otherwise variable supply.

Taking a cue from spider webs, UCLA researchers snag fresh water with vapor capture system
Taking a cue from spider webs, UCLA researchers snag fresh water with vapor capture system
Inspired by how dew drops form on spider webs, UCLA engineers and mathematicians have designed a unique and effective water vapor capture system that could be used to produce clean, fresh water, or to recycle industrial water that would otherwise be wasted. Their system is a dense array of parallel cotton threads strung vertically, with a steady stream of water droplets flowing down the strings.

Gummy-like robots could help prevent disease
Gummy-like robots could help prevent disease
EPFL scientists have developed microscopic, hydrogel-based muscles that can manipulate and mechanically stimulate biological tissue. These soft, biocompatible robots could be used for targeted therapy and to help diagnose and prevent disease. Human tissues experience a variety of mechanical stimuli that can affect their ability to carry out their physiological functions, such as protecting organs from injury.
