Guidelines have the potential to transform the fields of optoelectronics, bio-imaging and energy harvesting — ScienceDaily

Northwestern University researchers have developed a blueprint for understanding and predicting the properties and behavior of complex nanoparticles and optimizing their use for a broad range of scientific applications. These include catalysis, optoelectronics, transistors, bio-imaging, and energy storage and conversion. Recent research findings have successfully enabled the synthesis, or creation, of a wide variety of…

Crater counts on Pluto, Charon show small Kuiper Belt objects surprisingly rare — ScienceDaily

Using New Horizons data from the Pluto-Charon flyby in 2015, a Southwest Research Institute-led team of scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt. The evidence for the paucity of small Kuiper Belt objects (KBOs) comes from New Horizons imaging that revealed a dearth of small…

2015-2016 El Niño triggered disease outbreaks across globe — ScienceDaily

The 2015-2016 El Niño event brought weather conditions that triggered regional disease outbreaks throughout the world, according to a new NASA study that is the first to comprehensively assess the public health impacts of the major climate event on a global scale. El Niño is an irregularly recurring climate pattern characterized by warmer than usual…

Amoebae diversified at least 750 million years ago, far earlier than expected — ScienceDaily

Brazilian researchers have reconstructed the evolutionary history of amoebae and demonstrated that at the end of the Precambrian period, at least 750 million years ago, life on Earth was much more diverse than suggested by classic theory. The study, which was supported by São Paulo Research Foundation — FAPESP, revealed eight new ancestral lineages of…

How Capsella followed its lonely heart — ScienceDaily

The Brassicaceae plant family boasts a stunning diversity of fruit shapes. But even in this cosmopolitan company the heart-shaped seed pods of the Capsella genus stand out. An estimated 8 million years ago Capsella embarked on a different evolutionary pathway from its close relatives Arabidopsis and Camelina. This led to radically different shapes in the…
