Study finds the "squishy" outer shell of Venus may be resurfacing the planet
Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus's heat flow mechanism has been a mystery. A s.....»»

Researchers propose new mechanism for early chemical evolution
Scientists from The Ohio State University have a new theory about how the building blocks of life—the many proteins, carbohydrates, lipids and nucleic acids that compose every organism on Earth—may have evolved to favor a certain kind of molecula.....»»
Synergistic interplay mechanism of dual active sites on bimetallic oxide for syngas conversion
Catalytic syngas conversion is the key route to bridge the gap between various carbon resources and essential chemicals. Oxide-zeolite (OXZEO) bifunctional catalysis is a new platform for this conversion......»»
New multi-policy-based annealer for solving real-world combinatorial optimization problems

New mechanism proposed for why some psychedelics act as antidepressants
We know what receptors they bind, but where they bind them might matter, too. Enlarge (credit: VICTOR de SCHWANBERG/SCIENCE PHOTO LIBRARY) Psychedelic drugs are often used for entertainment purposes. But there have been.....»»
Researchers discover unique way snakes replace their teeth
A new study, led by a researcher from the Centre for Oral, Clinical & Translational Sciences at King's College London, has identified key differences in tooth replacement between snakes and other reptiles, and identified the mechanism that allows sna.....»»
Perovskites, a "dirt cheap" alternative to silicon, just got a lot more efficient
Silicon, the standard semiconducting material used in a host of applications—computer central processing units (CPUs), semiconductor chips, detectors, and solar cells—is an abundant, naturally occurring material. However, it is expensive to mine.....»»
Researchers reveal mechanism regulating rhodium migration and size redistribution in rhodium catalysts
The migration of Rh atoms under a gas/reactive environment is important for the dynamic restructuring and size redistribution of Rh catalysts in a variety of structure-sensitive catalytic reactions......»»
Researchers reveal new competition mechanism in vacuum ultraviolet photoionization of dichloromethane
A research group led by Prof. Li Haiyang from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has revealed a new competition mechanism in vacuum ultraviolet photoionization of dichloromethane using a home-buil.....»»
Autophagy: The molecular regulation of self-eating
Autophagy, or "self-eating", is an essential cellular quality control mechanism that clears the cell of protein aggregates and damaged organelles. This mechanism is inactive under normal conditions and only triggered upon persistent cellular stress......»»
New study opens the door to ultrafast 2D devices that use nonequilibrium exciton superdiffusion
Bound electron-hole pairs, or excitons, are the workhorses in layered transition metal dichalcogenide semiconductors. Like the negative and positive charge carriers from which it forms, the exciton exhibits great mobility that ultrafast transient dif.....»»
Two-beam ultrafast laser scribing of ultrafine graphene patterns
The Nobel Prize in Chemistry 2014 was awarded for the development of super-resolved fluorescence microscopy. Inspired by this work, scientists at Institute of Photonic Chips (IPC), University of Shanghai for Science and Technology (USST) have develop.....»»
Unlikely pairs of DNA elements and regulator proteins make small plant stem cells destined to become stomata
Researchers at Nagoya University in Japan, the University of Texas at Austin and the University of Washington have elucidated a mechanism that makes tiny plant stem cells develop stomata, the cellular valves of plants that facilitate global carbon cy.....»»
Insights into the mechanism of diurnal variations in methane emission from the stem surfaces of Alnus japonica
The greenhouse gas methane, or CH4 is produced in certain tree species, but how these mechanisms actually work is a matter of volatile debate, particularly with regard to the diffusive transport of CH4 gas through the trees......»»
New sensor enables "smart diapers," range of other health monitors
