Stars can create DNA precursors, suggests new experiment

Scientists at Berkeley Lab and the University of Hawaii have shown how DNA’s molecular precursors – carbon ring structures with embedded nitrogen atoms – could be created in the region surrounding a star. The new work adds to previous intriguing observations of what appear to be organic molecules in distant stellar environments. In the new […]

Artificial leaf clears developmental barrier

Putting together the chemical reactions that make photosynthesis happen has proven harder than scientists initially thought, but in a new paper in Nature Chemistry, Arizona State University (ASU) researchers describe the breakthroughs they have made toward perfecting a functional artificial leaf. The researchers hope their work will one day allow the inexpensive production of hydrogen […]

New Sorting Algorithm Aims To Sift Through All Possible Molecules

One of the problems in molecular synthesis is that there simply “aren’t enough atoms in the universe to make all the reasonable-sized molecules that could be made,” explains Duke University chemistry professor David Beratan. To help sift through this giant haystack, he’s investigating a new computer method that could help scientists identify the best molecules […]
