All wound up: A reversible molecular whirligig
Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, which is important when u.....»»
New study finds that CRISPR/Cas9 leads to unexpected genomic changes
The widely used gene scissor (CRISPR/Cas) can modify the genetic content in cells to study the molecular roles of genes and has gained great clinical relevance in gene therapy to treat genetic diseases. A new study performed by Claudia Kutter's resea.....»»
Molecular fingerprint behind beautiful pearls revealed
Pearl oysters are an important aquaculture animal in Japan, as they produce the beautiful pearls that are sought after for necklaces, earrings, and rings. In the early 1990s, this aquaculture industry was bringing in around 88bn yen annually. But, in.....»»
Experimental data validates new theory for molecular diffusion in polymer matrices
After several years of developing the theoretical ideas, University of Illinois Urbana-Champaign researchers have validated multiple novel predictions about the fundamental mechanism of transport of atoms and molecules (penetrants) in chemically comp.....»»
Electrons zip along quantum highways in new material
Researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME) have discovered a new material, MnBi6Te10, which can be used to create quantum highways along which electrons can move. These electron thoroughfares are potenti.....»»
Researchers develop hierarchically self-assembled homochiral helical microtoroids
Chirality is essential for life, which can be observed in biological systems hierarchically from the molecular level to macromolecules and higher ordered nanostructures, such as 3D enzymes and micrometer cell membranes. Chirality is precisely control.....»»
Parallel alignment of dressing fibers accelerates wound healing
A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their research has recently been.....»»
Eco-activist attacks on museum artwork ask us to figure out what we value
In the last few weeks climate change activists have perpetrated various acts of reversible vandalism against famous works of art in public galleries......»»
Fluorescence achieved in light-driven molecular motors
Rotary molecular motors were first created in 1999, in the laboratory of Ben Feringa, Professor of Organic Chemistry at the University of Groningen. These motors are driven by light. For many reasons, it would be good to be able to make these motor m.....»»
Using molecular isomerization in polymer gels to hide passcodes
A team of researchers at the Chinese Academy of Sciences, working with a colleague from the State University of New Jersey, has developed a gel-based code-hiding system that uses combinations of water, light and heat to hide and reveal hidden codes......»»
The Sci-Fi Dream of a ‘Molecular Computer’ Is Getting More Real
Chemists have long conceptualized tiny machines that could fabricate drugs, plastics, and other polymers that are hard to build with bigger tools......»»
Cellular mechanisms explain differences in hare species" biology and help to understand their evolution
Researchers from the University of Eastern Finland and Tampere University have published in the journal Molecular Ecology a comprehensive study on the significance of species differences for the most central cell maintenance mechanisms. The researche.....»»
Magnetic molecules on surfaces: Advances and challenges in molecular nanoscience
In the field of molecular magnetism, the design of devices with technological applications at the nanoscale—quantum computing, molecular spintronics, magnetic cooling, nanomedicine, high-density information storage, etc.—requires those magnetic m.....»»
Enzymatic reactions: Researchers reveal a regulatory mechanism by which life controls and organizes itself
Inside cells, molecular droplets form defined compartments for chemical reactions. Not only sticky interactions between molecules, but also dynamic reactions can form such droplets, as was found by researchers from the Max Planck Institute for Dynami.....»»
New study shows how to learn the equations of cell migration
When you cut yourself, a mass migration begins inside your body: Skin cells flood by the thousands toward the site of the wound, where they will soon lay down fresh layers of protective tissue......»»
2022 Nobel Prize in Chemistry Awarded for a New Way of Building Molecules
Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless share the Nobel Prize in Chemistry for discovering an easy way to “click” molecular building blocks together.....»»
Study finds effect of Earth"s orbit on ancient microorganisms
Curtin University researchers studying molecular fossils or "biomarkers" from deep beneath the Chicxulub impact crater have found evidence of how microorganisms changed in response to fluctuations in the Earth's climate, offering clues about how the.....»»
Scientists found a molecule that destroys even the worst cancers in mice
Scientists working at Yale and the University of Rhode Island (URI) have discovered a new molecular cancer treatment that can home in on cancer cells and eradicate tumors in mice. The tests so far have proven to offer exceptionally grand results, and.....»»
