Corals convert sunscreen chemical into a toxin that kills them
The chemical in the sunblock is fine until the coral alters it. Enlarge (credit: Justin Lewis) Medical authorities have spent years convincing people to use sunscreen to limit their exposure to UV light. But that effort has ha.....»»
Affordable iron catalysts offer a sustainable route to prized Z-alkenes
Chemists from the National University of Singapore (NUS) have developed an iron-catalyzed method that overcomes a significant challenge in the sustainable synthesis of trisubstituted Z-alkenes by inserting two alkyl chemical groups into a type of com.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Lignin-based sunscreen offers natural and high-performance UV protection
In a significant breakthrough for the cosmetics industry, researchers have developed a new type of sunscreen using lignin, a naturally abundant polymer, and titanium dioxide (TiO2). The study, led by Yarong Li and Zhiguang Tang, was published in the.....»»
Transforming caragana waste into nutritious ruminant feed
In an advance for agricultural waste management, scientists from the Chinese Academy of Sciences have devised a method to convert Caragana korshinskii Kom. waste, a common forestry byproduct in China, into a potential ruminant feed. The research, pub.....»»
"Tamed" molecules for more sustainable catalysts: Chemists succeed in synthesizing a spectacular gallium compound
Catalysts play an important role in the manufacture of many products that we encounter in everyday life—for example in cars for exhaust gas purification or in the chemical industry in the production of fertilizers. Catalysts ensure that these react.....»»
Biologists sequence proteins by pulling them through nanopores

Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
How diversity in heat tolerance can help protect coral reefs
New research out of Southern Cross University has found previously undocumented variation in coral heat tolerance on Australia's Great Barrier Reef, giving hope that corals' own genetic resources may hold the key for us to help in its recovery and ad.....»»
Deeper corals may help shallow reefs recover in the Florida keys
Since the 1970s, coral reefs in the Florida Keys National Marine Sanctuary (FKNMS) have experienced catastrophic declines in coral cover, with as much as a 50% reduction between 1998 and 2011 alone. Although coral reefs within the FKNMS have been hea.....»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
