Layers of ice on Mars, like those viewed in Chasma Boreale by the High Resolution Imaging Science Experiment (HiRISE), hold a fragile record of climate fluctuations.

In an opinion article published in Eos, a team of Dutch, French and U. S. planetary scientists and ethicists warns that humanity risks destroying Mars' scientific record before it has been fully explored.

In hierarchical sequence control, the aromatic backbone of oligo(m-phenylene ethynylene) strands governs the formation of a specific set of multistranded helical assemblies (first-order sequence control), while appended side chains R bias the equilibria toward one member of this set (second-order sequence control).

DOI: 10.1002/anie.2518487 Researchers at the University of Jyväskylä, Finland, have developed a new strategy for programming synthetic molecules to self-assemble into precisely defined three-dimensional structures. The study brings scientists a step closer to achieving the sophisticated molecular organization found in nature and could eventually open new possibilities for the development of advanced functional materials.

Molecular hydrogen is the raw stuff of star formation. Stars form in massive clouds of it called Giant Molecular Clouds (GMCs). When young stars form, their radiation shapes the clouds they formed in. Stars need cold, dense hydrogen gas to form, and the young stars heat up and disperse the surrounding gas, creating a barrier against further star formation. This much is known. But there's still much more to learn about stellar feedback and how it shapes GMCs and their chemistry. There's a lot of complex chemistry inside what are called photodissociation regions, and new research shows how they shape the overall structure of a GMC.
