Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the Earth's cl.....»»
Drawing a line back to the origin of life: Graphitization could provide simplicity scientists are looking for
Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible conditions for life's e.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Peptides on interstellar ice: Study finds presence of water molecules not a major obstacle for formation
A research team led by Dr. Serge Krasnokutski from the Astrophysics Laboratory at the Max Planck Institute for Astronomy at the University of Jena had already demonstrated that simple peptides can form on cosmic dust particles. However, it was previo.....»»
Cold Coulomb crystals, cosmic clues: Unraveling the mysteries of space chemistry
While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists for decades, as at l.....»»
Magnetism boosts hydrogen production in model catalysts
Researchers at the University of Twente have shown how to improve the efficiency of hydrogen production in an experimental setup. They showed that the magnetic order of the molecules plays a critical role......»»
Palladium nanocluster catalyst supports highly efficient and regioselective hydrogenation of epoxides
Alcohols are widely applied in life sciences and the chemical industry. Selective hydrogenation of epoxides using hydrogen molecules as a reductant is considered to be one of the most facile and atom-economical strategies for alcohol synthesis. Howev.....»»
Compulsory income management doing more harm than good, Australian study finds
Compulsory income management (CIM) in the Northern Territory is perceived to be ineffective in reducing harm, can contribute to situations of family violence and is incompatible with the needs of welfare recipients, a new study led by Charles Darwin.....»»
A molecular moon lander: Insight into molecular motion on surfaces at the nanoscale
For years, scientists have been intrigued by how molecules move across surfaces. The process is critical to numerous applications, including catalysis and the manufacturing of nanoscale devices......»»
Scientists find new ways to convert inhibitors into degraders, paving the way for future drug discoveries
Researchers have discovered ways to convert inhibitor-style targeted cancer drugs into small molecules known as degraders, which help destroy cancer-promoting proteins in cells......»»
Altered oceanic crust may contribute to arc magmas
As an important subduction component, altered oceanic crust (AOC) is widely distributed on the oceanic subducting slab and may contribute significantly to the chemistry of arc magmas. However, identifying this contribution in arc magmas is challengin.....»»
Oxidant pollutant ozone removes mating barriers between fly species, study finds
Insect pheromones are odor molecules used for chemical communication within a species. Sex pheromones play a crucial role in the mating of many insects. Species-specific odors attract males and females of the same species. At the same time, they main.....»»
New molecular device unlocks potential for targeted drug delivery and self-healing materials
In a new breakthrough that could revolutionize medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force......»»
A simple, inexpensive way to make carbon atoms bind together
The active ingredient in many drugs is what's known as a small molecule: bigger than water, much smaller than an antibody and mainly made of carbon. It's tough, however, to make these molecules if they require a quaternary carbon—a carbon atom bond.....»»
