| Open AccessPhotocured room temperature phosphorescent materials from lignosulfonate
It is elusive to manufacture room temperature phosphorescent (RTP) materials through effective and ambient processing approaches. Here the authors report the production of photocured RTP materials using lignosulfonate to act as RTP chromophore and photoinitiator, achieving easy preparation, low cost and good performance.

| Open AccessReal-world time-travel experiment shows ecosystem collapse due to anthropogenic climate change
Over 13 years, coastal Louisiana’s wetlands have been endangered by a sea-level rise rate comparable to what is expected later this century. While the rate may not persist over the next few decades, this natural experiment indicates a 75% drowning of these wetlands by 2070 under current carbon emissions.

Nutrient limitation is a well-known control of phytoplankton growth, but predicting specific responses in individual lakes based on nutrient data alone has proven challenging. Here, the authors show that long-term signals of chlorophyll-a dynamics in shallow lakes can be captured based on stoichiometric effects of N and P concentrations along a continuum of total N:total P ratios.
