From chemical graphs to structures
3D configurations of atoms dictate all materials properties. Quantitative predictions of accurate equilibrium structures, 3D coordinates of all atoms, from a chemical graph, a representation of the structural formula, is a challenging and computation.....»»
Study confirms Egyptians drank hallucinogenic cocktails in ancient rituals
A University of South Florida professor found the first-ever physical evidence of hallucinogens in an Egyptian mug, validating written records and centuries-old myths of ancient Egyptian rituals and practices. Through advanced chemical analyses, Davi.....»»
Toxin was released into the Congaree River in South Carolina: Agencies did little to stop it, greens say
High amounts of a toxic chemical are being discharged into the Congaree and Cooper rivers from plastics factories in South Carolina, but state and federal regulators are doing little to control the pollution, a new report says......»»
Mathematical approach can predict crystal structure in hours instead of months
Researchers at New York University have devised a mathematical approach to predict the structures of crystals—a critical step in developing many medicines and electronic devices—in a matter of hours using only a laptop, a process that previously.....»»
Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Scientists compile library for evaluating exoplanet water
By probing chemical processes observed in the Earth's hot mantle, Cornell scientists have started developing a library of basalt-based spectral signatures that not only will help reveal the composition of planets outside of our solar system but could.....»»
Bioluminescent proteins made from scratch enable non-invasive, multi-functional biological imaging
Bioluminescence is the natural chemical process of light creation in some living creatures that makes fireflies flicker and some jellyfish glow. Scientists have long been interested in borrowing the secrets of these animals' light-producing genes to.....»»
Self-organization of living matter into complex structures: How light pattern impacts aggregation of active filaments
When active filaments are exposed to localized illumination, they accumulate into stable structures along the boundaries of the illuminated area. Based on this fact, researchers at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS).....»»
High-performance inkjet print head enhances bioprinting productivity
Bioprinting is a technology used to create three-dimensional structures, such as human tissues or organs, using bio-inks made of cells and hydrogels. However, conventional inkjet technology has difficulty dispensing bio-inks that are sensitive to tem.....»»
Study reveals why carbon boosts metal nanoparticle catalysts
Precious metals play an important role in the chemical industry as catalysts: With the help of silver, platinum, palladium or other elements, chemical reactions can take place that would otherwise not progress or would only progress at a much lower r.....»»
Laser spectroscopy study explores nuclear structure of fermium and nobelium isotopes
University of Liverpool researchers are part of an international research collaboration that has shed light on what happens at the extremes of neutron and proton numbers, in search of where the periodic table of chemical elements ends......»»
Computational chemistry promises to upset traditional methods of chemical synthesis
The process of discovering and designing new chemicals has always been arduous—Sijia Dong wants to change that. As an assistant professor in the department of chemistry and chemical biology, with affiliations in physics and chemical engineering, Do.....»»
Researcher highlights the combined effects of climate change and chemical pollution
Traditionally, research has focused on either climate change or chemical pollution in isolation, overlooking their combined effects. This oversight creates a blind spot in understanding the full scope of risks to ecosystems and human health......»»
Hard in theory, easy in practice: Why graph isomorphism algorithms seem to be so effective
Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop algorithms that can compare any two graphs......»»

Researchers at the University of Liverpool have developed AI-driven mobile robots that can carry out chemical synthesis research with extraordinary efficiency......»»
Bioinspired hydrogels harness sunlight: A step closer to artificial photosynthesis
Mimicking how plants convert sunlight into energy has long been a dream for scientists aiming to create renewable energy solutions. Artificial photosynthesis is a process that seeks to replicate nature's method, using sunlight to drive chemical react.....»»
Ultrasensitive nanoscale sensors can identify lung cancer through exhaled isoprene
Exhaled breath contains chemical clues to what's going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses—and improve patients' prospects. In a study in ACS.....»»
Flow of the future: AI models tackle complex particle drag coefficients
Accurately modeling particle movement through fluids is crucial in fields ranging from chemical engineering to aerospace. The drag coefficient, which influences how particles settle and move in fluid environments, is a core factor in these calculatio.....»»
Researchers discover localized pain relief using known chemical reaction
