Nanomedicine paves the way for new treatments for spinal cord injury
A Study by Politecnico di Milano and Istituto Mario Negri has been published in Advanced Materials.
Making elbow room: Giant molecular rotors operate in solid crystal
Solid materials are generally known to be rigid and unmoving, but scientists are turning this idea on its head by exploring ways to incorporate moving parts into solids.
MXene, a dream new material, paves the way for mass production
The research team led by Seung-Cheol Lee, director of the Indo-Korea Science and Technology Center(IKST) at the Korea Institute of Science and Technology(KIST), has developed a method to predict the distribution of molecules on the surface using the magnetoresistance property of MXene.
Gold buckyballs, oft-used nanoparticle ‘seeds’ are one and the same
Rice University chemists have discovered that tiny gold “seed” particles, a key ingredient in one of the most common nanoparticle recipes, are one and the same as gold buckyballs, 32-atom spherical molecules that are cousins of the carbon buckyballs discovered at Rice in 1985.
UC Irvine-led researchers reveal new molecular mechanism for stimulating hair growth
Irvine, Calif., June 21, 2023 — The process by which aged, or senescent, pigment-making cells in the skin cause significant growth of hair inside skin moles, called nevi, has been identified by a research team led by the University of California, Irvine. The discovery may offer a road map for an entirely new generation of molecular therapies for androgenetic alopecia, a common form of hair loss in both women and men.
Watching Molecules Relax in Real Time
Berkeley Lab scientists have visualized the distortions of chemical bonds in a methane molecule after it absorbs light, loses an electron, and then relaxes. Their study provides insights into how molecules react to light, which can help develop new methods to control chemical reactions.
Leaps in artificial blood research aim to improve product safety, efficacy
Researchers have made huge strides in ensuring that red blood cell substitutes – or artificial blood – are able to work safely and effectively when transfused into the bloodstream.
Newly revealed properties of melanin ‘ingredient’ could advance bioelectronics
After nearly a century of scientific inquiry, scientists have at last been able to characterize a key component in the substance responsible for giving countless living organisms their color.
How football-shaped molecules occur in the universe
For a long time it has been suspected that fullerene and its derivatives could form naturally in the universe.
How Earth’s molecules got their “handedness”
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 molecular structure.
Chemists design brand-new kind of nanomaterial
Scientists developed a way to make carbon-based molecules with a unique structural feature: interlocking rings.
UC Irvine scientists create new chemical imaging method
Irvine, Calif., Jan. 4, 2023 – A new visualization technology that captures spectral images of materials in the mid-infrared part of the electromagnetic spectrum has been developed by scientists at the University of California, Irvine. The discovery, which was recently featured on the cover of the journal Science Advances, promises to help researchers and industries across many fields, including medical and tech, quickly visualize the chemical composition of various materials or tissues.
A better way to create compounds for pharmaceuticals, other chemicals
What do gunpowder, penicillin and Teflon all have in common? They were inventions that took the world by storm, but they were all created by complete accident.
Cleveland Clinic Study Links Gut Microbiome and Aggressive Prostate Cancer
Cleveland Clinic researchers have shown for the first time that diet-associated molecules in the gut are associated with aggressive prostate cancer, suggesting dietary interventions may help reduce risk. Findings from the study were published in Cancer Epidemiology, Biomarkers & Prevention.
Rutgers Professor Joan Bennett Elected to American Academy of Arts & Sciences
Joan W. Bennett, a Distinguished Professor of plant biology and pathology at Rutgers University–New Brunswick, has been elected to the American Academy of Arts & Sciences. She joins neurosurgeon and CNN medical correspondent Sanjay Gupta, NASA’s Goddard Space Flight Center atmospheric scientist Ann Thompson and media entrepreneur and philanthropist Oprah Winfrey.
A project by Russian scientists to help create capsules for targeted drug delivery
Scientists from MIPT and ITMO University and their colleagues have studied the formation and growth of crystals from simple organic molecules into large associations. These experiments will help create capsules for targeted drug delivery to specific tissues in the human body. The scientific paper was published in the journal Crystal Growth & Design.
Charges Cascading Along a Molecular Chain
Removing one charged molecule from a one-dimensional array causes the others to alternately turn ‘on’ or ‘off,’ paving the way for information transfer in tiny circuits
UCI scientists get ‘initial hit’ in developing drug to treat COVID-19
Irvine, Calif., Aug. 5, 2020 – When the coronavirus pandemic hit, almost everyone at the University of California, Irvine – and colleges across the nation – had to abandon campus. But James Nowick, professor of chemistry, was not a part of that exodus. That’s because his lab, which designs and constructs chemical molecules, had the right equipment to help in the global push to find treatments for COVID-19.
