Enticed by the brilliant green hues of copper acetate and copper resinate, some painters in the Renaissance period incorporated these pigments into their masterpieces. However, by the 18th century, most artists had abandoned the colors because of their tendency to darken with time. Now, researchers reporting in ACS' journal Inorganic Chemistry have uncovered the chemistry behind the copper...
The International Monitoring System is the top global seismic network for monitoring nuclear weapon tests around the world. To expand the system's detection capabilities, however, international monitors should seek out the data, methods and expertise of smaller regional seismic networks.
Scientific collaborations across the globe are an important part of modern research. However, political and economic strife between governments, such as current tensions between the U.S. and China, can threaten these vital connections, according to an article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.

The find provides new insights into the evolution of these animals and sheds light on the recovery of marine ecosystems after the mass extinction occurred 66 million years ago.
Researchers have uncovered sex-based differences in the development of the hippocampus and amygdala. These brain areas have been implicated in the biology of several mental disorders that impact males and females differently. The findings may help researchers better understand sex-based differences in the emergence of mental disorders during adolescence and early adulthood.
Metabolic analysis involves ongoing biological pathways and can be more distal than proteomic/genomic approaches to in vitro diagnostics (IVD). However, point-of-care (POC) metabolic analysis needs special designed materials to detect target biomarkers of low concentration in complex biosystems.
The neutrino event IceCube 170922A, detected at the IceCube Neutrino Observatory at the South Pole, appears to originate from the distant active galaxy TXS 0506+056, at a light travel distance of 3.8 billion light years. TXS 0506+056 is one of many active galaxies and it remained a mystery why and how only this particular galaxy generated neutrinos so far.

White sharks are top predators in the marine environment, but unlike their terrestrial counterparts, very little is known about their predatory activity underwater, with current knowledge limited to surface predation events. Now, a team of international scientists has used video- and data-logging technology to shed new light on predator-prey interactions of these mighty sea creatures.
Quantum physics is difficult and explaining it even more so. Associate Professor Holger F. Hofmann from Hiroshima University and Kartik Patekar from the Indian Institute of Technology Bombay have tried to solve one of the biggest puzzles in quantum physics: how to measure the quantum system without changing it?
One of the worst symptoms associated with inflammation or cancer of the pancreas is severe chronic pain. Pancreatic pain is difficult to treat, because many painkillers prove ineffective in pancreatic patients. In a recent study, medical researchers discovered the cause of this phenomenon for the first time: a particular neuroenzyme in the body is present in the nerves of the organ in high...
Scientists have developed new technology, dubbed 'Knocker', which identifies objects and executes actions just by knocking on them with the smartphone. Software powered by machine learning of sounds, vibrations, and other reactions will follow the users' directions.
Topological insulators are quantum materials, which, due to their exotic electronic structure, on surfaces and edges conduct electric current like metal, while acting as an insulator in bulk. Scientists have now demonstrated how to tell apart topological materials from their regular -- trivial -- counterparts within a millionth of a billionth of a second by probing it with ultra-fast laser light.
We make food decisions several times a day - from what time we eat to how much - but a new study has found we are not very good at judging the energy-density of what we consume.
Scientists, inspired by the clingfish's suction power, set out to develop an artificial suction cup that borrows from nature's design. Their prototype actually performed better than the clingfish.
Researchers have developed a 'coloring-by-shrinking' method to print arbitrary 3D microscopic objects exhibiting structural colors. The design consisted of woodpile photonic crystals with varying lattice constants as the 3D building blocks. These structures remain colorless until they are heat treated, causing them to shrink and manifest color, a result of their lattice constants shrinking down...
