Researchers Store Digital Data in DNA

Researchers from the University of Washington and Microsoft have stored digital images in DNA. The team of computer scientists and electrical engineers has detailed one of the first complete systems to encode, hold, and retrieve digital data using the molecules, which can store information millions of times more compactly than current archival technologies.

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.

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.
