Peptide induces chirality evolution in a single gold nanoparticle  

Scientists have created a synthesis method to make optically active and chiral gold nanoparticles using amino acids and peptides for the first time. Many chemicals significant to life have mirror-imaged twins and such characteristics are conventionally called as chirality. This study describes how the chirality, typically observed in organic molecules, can be extended to three-dimensional metallic nanostructures. The research will be published in Nature and featured in its cover.

Researchers have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together.

How to improve habitat conservation for migrating cranes  

Every year, endangered whooping cranes travel along a 4,000-kilometer corridor linking their Canadian nesting grounds and their winter home in Texas. Habitat in their path through the northern Great Plains is being lost at an alarming rate, but identifying key spots for protection is a challenge. Now, researchers behind a new study have created a model of whooping crane habitat use with the potential to greatly improve the targeting of conservation efforts during their migration.

Study reveals new Antarctic process contributing to sea level rise and climate change  

A new study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise. The research found that glacial meltwater makes the ocean's surface layer less salty and more buoyant, preventing deep mixing in winter and allowing warm water at depth to retain its heat and further melt glaciers from below.
