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.....»»
Chemists develop new sustainable reaction for creating unique molecular building blocks
Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers ha.....»»
Chemical production gets a cleaner boost from a new electrochemical method
A new electrochemical method can make chemical production cleaner and more energy-efficient......»»
New report on Great Barrier Reef shows coral cover increases before onset of serious bleaching, cyclones
Most of the underwater surveys contributing to these findings, published today, were conducted before and during the recent mass bleaching event, one of the most extensive and serious on record, and have not yet captured how many corals survived or d.....»»
Google kills Chromecast, replaces it with Apple TV and Roku Ultra competitor
The rebranded device appears better in every way but the price. This is Google's new streaming box, the Google TV Streamer. It's meant to sit on your media console instead of h.....»»
Researchers reveal atomic-scale details of catalysts" active sites
The chemical and energy industries depend upon catalysts to drive the reactions used to create their products. Many important reactions use heterogeneous catalysts—meaning that the catalysts are in a different phase of matter than the substances th.....»»
Double whammy antibiotic makes antibiotic resistance much harder—new study
Most antibiotics are natural products of bacteria and other microorganisms from the environment. They are part of a silent chemical warfare among microorganisms in soils, rivers and seas right now. The fact that they are natural products that have be.....»»
Sunscreens can hurt the marine environment—how to choose one that"s healthy for you and the sea
Choosing which sunscreen to use can be mind-boggling. Should you choose one with the highest sun protection factor (SPF) or another with "reef-safe" or "coral-friendly" credentials? Is it best to opt for a spray or a lotion? What's the difference bet.....»»
Machine learning discovers "hidden-gem" materials for heat-free gas separation
Chemical separation, including gas separation, is a common process that is required for manufacturing and research. It accounts for a whopping 15% of U.S. energy consumption and produces millions of tons of carbon emissions......»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
Heat claims 175,000 lives a year in Europe: WHO
Heat kills over 175,000 people a year in Europe, where temperatures are rising quicker than the rest of the globe, the World Health Organization's (WHO) European branch said Thursday......»»
Researchers develop a concept for efficiency-enhanced noble-metal catalysts
The production of more than 90% of all chemical products we use in our everyday lives relies on catalysts. Catalysts speed up chemical reactions, can reduce the energy required for these processes, and in some cases, reactions would not be possible a.....»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»

Metallic nanosheets curl into nanovesicles
Inspired by the cell membrane structure, researchers, led by Dr. Xiaoqing Huang (State Key Laboratory of Physical Chemistry of Solid Surfaces, College of Chemistry and Chemical Engineering, Xiamen University) and Dr. Qi Shao (College of Chemistry and.....»»
New perspectives for using corals in climate research
Ancient ocean temperatures are most commonly reconstructed by analyzing the ratio of different oxygen atoms in the calcium carbonate remains of fossils. However, this presents many challenges, including a combination of biological processes known as.....»»
3D models provide unprecedented look at corals" response to bleaching events
In a study, published July 31 in the journal PLOS ONE, marine biologists from Scripps Institution of Oceanography at UC San Diego and Arizona State University provide a first-of-its-kind glimpse into coral "bleaching" responses to stress, using imagi.....»»
Research team achieves faster and more efficient synthesis of high-density RNA microarrays
An international research team led by the University of Vienna has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used.....»»
Green hydrogen: "Artificial leaf" becomes better under pressure
Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so-called photoelectrochemical cells (PEC cells). A research team at HZB has now sh.....»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
