Carbon is famous for its allotropes, including humble graphite, flashy diamond, and satisfyingly symmetrical buckminsterfullerene. But allotropes of nitrogen, carbon's neighbor in the periodic table, are rare and usually fleeting. Now chemists at Justus Liebig University Giessen have created and isolated the neutral nitrogen allotrope hexanitrogen, or N 6-a string of six nitrogen atoms held together by four double bonds and one single bond in the molecule's center.

Robert A. Holton, a retired Florida State University professor, died at his home in Tallahassee, Florida, on May 21 at the age of 81. Holton is best known for his work on the anticancer drug Taxol (paclitaxel). The molecule was first discovered in scant quantities in the bark of the Pacific yew tree, Taxus brevifolia, during a study initiated by the National Cancer Institute.

Being green is a matter of life or death for Tettigonia cantans. Also known as upland green bush crickets, these insects' green hue lets them hide from predators in the fens, marshes, mountain meadows, and potato fields where they live-over a region that extends from the Pyrenees to China. Researchers have now discovered that the bush crickets' green camouflage arises from a protein that simultaneously binds both yellow chromophores and blue chromophores.

Little children often dream of becoming astronauts or deep-sea explorers, but at age 5, Herdeline Ardoña wanted to be a chemical engineer. As career aspirations go, it's a precocious choice. But Ardoña says that she was inspired by her grandmother, Adela Mallari, a chemical engineer who worked for the government of the Philippines, where Ardoña grew up. Her grandmother was well respected in the community, so "I had a very positive view of what a female engineer looks like," Ardoña says.

Check out this supramolecular snub cube. Cool chemistry from Huang Wu and the late @sirfrasersays of the University of Hong Kong along with Wenping Hu and Yu Wang of Tianjin University. My latest in @cenmag https://t.co/SOfaDLlQ0o https://t.co/UxIpOBSuZb
So sad to hear we've lost @sirfrasersays. He was always generous to me as a reporter for @cenmag and kind to me as a human being. My thoughts are with his family, friends, and colleagues. https://t.co/92uAzyT6z0
With apologies to @ChappellRoan and @LongLabCal Baby, do you like this zinc(H)? We made this MOF to capture C(O2) Over 199 degrees When you’re tackling global warming, tackling global warming Thanks to my @cenmag colleagues who encouraged the lede https://t.co/pV9ohu7yyy
