World’s smallest battery can power computer with the size of a grain of dust
Computers are getting smaller and smaller, just as current cell phones offer computing power similar to that of a laptop. And the trend toward miniaturization continues. Smart dust applications (tiny microelectronic devices),…
MIT’s solar-powered system offers a route to inexpensive desalination
MIT researchers have developed a solar-powered desalination system that is more efficient and less expensive than previous methods. An estimated two-thirds of humanity is affected by shortages of water, and many such…
Mosquitoes are seeing red: These new findings about their vision could help you hide from these disease vectors
New research led by scientists at the University of Washington indicates that a common mosquito species — after detecting a telltale gas that we exhale — flies toward specific colors, including red,…
Achieving a milestone, scientists regrow frog’s lost leg
Frogs briefly treated with a five-drug cocktail administered by a wearable bioreactor were able to regrow a functional, nearly complete limb. For millions of patients who have lost limbs for reasons ranging…
