EEE / Electronic skin feels the heat, hears the sound
« on: November 20, 2016, 06:42:15 PM »
A new electronic skin can feel the grain of sand paper, the heat and beat of a person’s pulse — and listen to Richard Feynman’s voice, too.

Rubbery plastic-and-graphene film mimicking the structure of human skin can detect texture, temperature, pressure and sound, Hyunhyub Ko and colleagues report October 30 in Science Advances.

It’s the first time anyone has demonstrated an e-skin that can sense so many different kinds of stimuli, says Stanford University materials scientist Alex Chortos. “That’s the innovative and impressive part of this work.”

EEE / Roses rigged with electrical circuits
« on: November 20, 2016, 06:40:59 PM »
Garden-variety roses just got an electrical upgrade.

Playing off the thirst of plant vascular systems, a team of Swedish researchers cut roses (Rosa floribunda) and set them in water containing specially designed organic molecules that can conduct and process electricity. The molecules linked up to form “wires” in the xylem, which pumps water and nutrients up from plant roots. When zapped with a charge, the wires conducted electricity without damaging the plant, the researchers write November 20 in Science Advances. Similar bioelectrical molecules induced roses’ leaves to light up and change color.

This isn’t the first time researchers have injected plants with electrical materials, but it is the first time they’ve used the plants’ own vascular system to form a circuit. The technology could provide a means of manipulating plant biology for scientific research, to harvest energy or to tweak plant physiology without the need for genetic engineering.

EEE / SpaceX rocket sticks its landing
« on: November 20, 2016, 06:39:49 PM »
A rocket flying toward the ground is usually a bad sign, but for aerospace company SpaceX, it was a huge success. With engines blazing, the first section of a Falcon 9 rocket returned safely to Earth December 21 after a launch from Cape Canaveral Air Force Station in Florida, landing vertically on a platform just down the road.

The landing is a milestone for the company; earlier attempts to land on a barge at sea didn’t go as well. For the latest launch, the rocket stage flew to about 75 kilometers before turning around, leaving the rest of the rocket to deliver a package of satellites into low Earth orbit.

Historically, spent rocket stages have been jettisoned and lost at sea. Reusable stages may greatly reduce costs for future flights.

EEE / Succession of satellites keep eye on Earth
« on: November 20, 2016, 06:39:04 PM »
Search for water, oil aided by spacecraft — The secret sources of water, fuel and minerals … may be discovered by using a new tool for geologists — an orbiting spacecraft. Cameras which detect infrared, ultraviolet and visible light and which orbit at a height of 100 or more miles will be an immense aid to geologists mapping the contours … of the Earth’s surface. — Science News Letter, January 22, 1966

Update
Six years later, in 1972, NASA and the U.S. Geological Survey launched the first of the Landsat satellites, spacecraft built to gather images of Earth. The latest, Landsat 8, debuted in 2013 and sends a minimum of 400 scenes a day. Its specialized cameras can monitor plankton and sediment in shallow waters, measure land temperatures and track dust and smoke moving through the atmosphere. Data from the Landsat satellites have informed climate and carbon cycle research, disaster recovery and urban planning. Last April, NASA announced that work had begun on Landsat 9, planned for launch in 2023.
