In 2018, a new species of centipede graced the pages of the prominent taxonomy journal
Zootaxa. More than 14 centimeters long, with striking teal-colored legs, it lives in the montane and mossy forests of the Philippines. Now, however, the centipede is in a harsh spotlight. The Philippine government says the Spanish neurologist and amateur biologist who described the species acquired his specimens illegally.
Neither the journal’s editors nor its peer reviewers caught the lapse and the journal has no policy requiring documentation that specimens have been collected with proper permits. Some editors tell
Science that should change. Others worry about hampering research when undescribed species are vanishing fast. And all agree that journals would struggle to enforce any such rules, given the wide variation in countries’ legal requirements. “There is simply no way for a journal to police this,” says Maarten Christenhusz, an independent botanist and editor-in-chief of the

Congratulations to the 118 members of the 2021 class of OSA Fellow Members, who will be recognized at OSA conferences throughout the year for scientific, engineering and technological contributions, as well as industry leadership and service to OSA and the global optics community.
The 2021 class of Fellows reflects the diverse and inclusive community that OSA serves. A record 261 nominations were received, making this program very competitive as no more than 10% of OSA’s total membership may be elected as Fellows. For more information, contact the OSA Awards Office (awards@osa.org; +1 202.416.1960) or go to www.osa.org/fellows.. Nominations for 2022 Fellows are due by 15 June 2022.

HOUSTON - (Dec. 14, 2020) - Nanomaterials researchers in Finland, the United States and China have created a color atlas for 466 unique varieties of single-walled carbon nanotubes.
The nanotube color atlas is detailed in a study in
Advanced Materials about a new method to predict the specific colors of thin films made by combining any of the 466 varieties. The research was conducted by researchers from Aalto University in Finland, Rice University and Peking University in China. Carbon, which we see as black, can appear transparent or take on any color of the rainbow, said Aalto physicist Esko Kauppinen, the corresponding author of the study. The sheet appears black if light is completely absorbed by carbon nanotubes in the sheet. If less than about half of the light is absorbed in the nanotubes, the sheet looks transparent. When the atomic structure of the nanotubes causes only certain colors of light, or wavelengths, to be absorbed,
