Study: Comet 67P/Churyumov-Gerasimenko’s Water Has Similar Molecular Signature to Earth’s Water
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have helped deliver water to Earth. This false-color four-image mosaic comprises images taken from a distance of 28.7 km from the center of Comet 67P/Churyumov-Gerasimenko on 3 February 2015. The mosaic measures 4.2 x 4.6 km.
Newly-Discovered Gene Enhances Photosynthetic Efficiency and Plant Productivity
Biologists have identified a new gene in California poplar trees (Populus trichocarpa) — named BOOSTER — that enhances photosynthesis and can boost tree height. Transgenic hybrid poplar with increased expression levels of BSTR enhanced photosynthesis efficiency and biomass under greenhouse conditions.

Researchers Create Smallest Walking Robot Yet
A team of researchers at Cornell University has created a new class of magnetically controlled microscopic robots (microbots) that operate at the visible-light diffraction limit. Termed diffractive robots, these microbots can interact with waves of visible light and still move independently, so that they can maneuver to specific locations to take images and measure forces
