Lakshmi Sandhana

When Lakshmi first encountered pig's wings in a petri dish, she realized that writing about scientists and imagineers was the perfect way to live in an expanding mind bubble. Articles for Wired, BBC Online, New Scientist, The Economist and Fast Company soon followed. She's currently pursuing her dream of traveling from country to country to not only ferret out cool stories but also indulge outrageously in local street foods. When not working, you'll find her either buried nose deep in a fantasy novel or trying her hand at improvisational comedy.

Wearable smart veins locator could help nurses see below the skin

By - May 14, 2014 6 Pictures
Getting a needle into a patient's vein can sometimes be a complicated process, especially if the veins aren't visible. Vein-spotting spectacles that see through a patient's skin could help avoid the damage caused by repeated needle pricks, and that's exactly what researchers at the University Teknologi Petronas (UTP), Malaysia, are developing. Their Smart Veins Locator is a wearable head-mounted display that allows nurses to see the patient's veins in real-time, by overlaying a map of their veins on top of their skin. Read More

Harvesting water out of thin air, might seem like a pipe dream, but the air-stable water droplet networks, currently being developed by Oak Ridge National Laboratory (ORNL) researchers could prove to be a step in the right direction. Created with the aid of a new technique, these water droplet networks could also potentially find use in membrane research and biological sensing applications. Read More

Inflatable flying saucers could help spacecraft land on Mars

By - May 13, 2014 6 Pictures
It's tough to slow down spacecraft descending through Mars' thin atmosphere at supersonic speeds, as they need to drop to a speed that allows them to land in one piece. This is why NASA is developing lightweight inflatable flying saucers that will fit around the outer rims of spacecraft such as human habitats, inflating as the habitats descend to permit a safe landing. The technology will allow astronauts to land bigger and heavier spacecraft on Mars without needing to carry massive atmospheric shields or huge amounts of extra fuel. Read More

The Mink 3D printer lets you create your own custom-colored makeup

By - May 7, 2014 1 Picture
Finding the exact shade of lipstick or eye shadow you have in mind can be tough, which is why Grace Choi, a Harvard Business School alumni, came up with the Mink – a 3D printer that lets you print out makeup in any color you fancy. Whether it's the color of a fruit, your friend's purse or a sunset, transforming that color into any kind of makeup is simply a matter of choosing it and hitting print. Read More

Air-purifying billboard does the work of 1,200 trees

By - May 6, 2014 1 Picture
Billboards could do more than just advertise, if scientists at the University of Engineering and Technology (UTEC) in Peru have their way. While UTEC's earlier billboard produced drinkable water, its latest creation scrubs the air free of pollutants. According to the team, a single billboard can do the work of 1,200 trees, purifying 100,000 cubic meters (3.5 million cubic feet) of air daily in crowded cities. Read More

KAIST's wireless charging system can charge 40 smartphones simultaneously

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), have developed a wireless charging system that can charge around 40 smart phones at a time, from a distance of 5 meters (16 ft). While we've examined numerous wireless charging systems, even one that transmits power to up to 9 m (30 ft), KAIST's prototype can power multiple devices within its range. It can deliver enough electrical juice, the scientists claim, to power many larger devices like fans, TVs and computers, simultaneously. Read More

Disney researchers 3D print speakers in any shape imaginable

By - April 30, 2014 9 Pictures
It's one thing to assemble a loudspeaker from 3D-printed components, but researchers at Disney have figured out a way to 3D print interactive loudspeakers in any shape imaginable, while also integrating speaker functionality into the whole object or just parts of it. Just envision 3D printing an entire loudspeaker in one step in the shape of Cinderella, and having sounds boom off her whole body or just her skirt. Read More
