NASA Measures Raindrop Sizes from Space

For the first time, scientists have three-dimensional snapshots of raindrops and snowflakes around the world, thanks to the joint NASA and Japan Aerospace Exploration Agency Global Precipitation Measurement (GPM) mission. With the new global data on raindrop and snowflake sizes, scientists can improve rainfall estimates from satellite data and numerical weather forecast models.

Researchers Turn Carbon Dioxide into Concrete

A new system developed by UCLA researchers captures carbon from smokestacks and processes the C02 into a new building material that could replace concrete. The tiny cones of the "CO2NCRETE" material are fabricated using 3D printers.

New Flow Battery Offers Lower-Cost Energy Storage

A new flow battery technology is projected to cost 60 percent less than today's standard flow batteries. The lower cost is due to the battery's active materials being inexpensive organic molecules, compared to the commodity metals used in today's flow batteries.

New Ways to Construct Contactless Magnetic Gears

Magnetic gears transmit rotary motion like mechanical gears but instead of teeth they use magnetic attraction and repulsion between rotating magnets. Magnetic gears have several advantages over mechanical gears. The main one is the absence of direct contact between the parts.

Wall-Climbing Drone Flies and Sticks to Target

Researchers have developed the CAROS (Climbing Aerial RObot System) wall-climbing robot with higher mobility than existing wall-climbing robots because it can fly. It also can restore its pose after an accidental fall due to an unexpected disturbance. Since the robot can stick to the surface, it can perform close inspection and maintenance of the structure.

Graphene-Based Device Improves Water Filtering

According to the World Economic Forum’s Global Risks Report, lack of access to safe, clean water is the biggest risk to society over the coming decade. A new graphene-based filter built by Monash University and the University of Kentucky allows water and other liquids to be filtered nine times faster than leading commercial devices.

Algorithm Makes Hyperspectral Imaging Faster

Researchers from North Carolina State University and the University of Delaware have developed an algorithm that can quickly and accurately reconstruct hyperspectral images using less data. The images are created using instruments that capture hyperspectral information succinctly, and the combination of algorithm and hardware makes it possible to acquire hyperspectral images in less time and to store those images using less memory.
