How molecular clusters in the nucleus interact with chromosomes
A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that's not all that's tucked away in there. The nucleus is also home to small bodies called nucleoli—clusters of proteins and RNA that help build ribosomes......»»
Scientists learn how to drug wily class of disease-causing enzymes
UCSF scientists have discovered how to target a class of molecular switches called GTPases that are involved in a myriad of diseases from Parkinson's to cancer and have long been thought to be "undruggable.".....»»
Study: Playing Dungeons & Dragons helps autistic players in social interactions
"I can make a character quite different from how I interact with people in real life." Enlarge / Researchers say that Dungeons & Dragons can give autistic players a way to engage in low-risk social interactions. (credit: Nicole H.....»»
Researchers develop molecular biosensors that only light up upon binding to their targets
Biosensors—devices that use biological molecules to detect the presence of a target substance—have enormous potential for detecting disease biomarkers, molecules-in-action in diverse biological processes, or toxins and other harmful substances in.....»»
Labs collaborate to enhance imaging tools for cell observation
Two labs at the University of Utah's Department of Chemistry joined forces to improve imaging tools that may soon enable scientists to better observe signaling in functioning cells and other molecular-scale processes central to life......»»
Unveiling the molecular mechanisms linking aging with neurodegenerative diseases
Aging is the prime cause of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. But what exactly increases the prevalence of these brain disorders as one grows older? The molecular forces l.....»»

Hubble zooms into the rosy tendrils of Andromeda
Clusters of stars set the interstellar medium ablaze in the Andromeda galaxy about 2.5 million light-years away. Also known as M31, Andromeda is the Milky Way's closest major galaxy. It measures approximately 152,000 light-years across and, with almo.....»»
Researchers explore design of polar crystalline solids of pure molecular materials
Harmeet Bhoday, a Missouri S&T Ph.D. student in chemistry from Chandigarh, India, was the lead author of an article titled "Perfect Polar Alignment of Parallel Beloamphiphile Layers: Improved Structural Design Bias Realized in Ferroelectric Crystals.....»»
Chiral molecule research achieves near-complete separation in quantum states
In a study titled "Near-complete chiral selection in rotational quantum states" published in Nature Communications, the Controlled Molecules Group from the Molecular Physics Department of the Fritz Haber Institute has made a significant leap forward.....»»
Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
Light microscopy study reveals molecular density changes during mitotic chromosome condensation
A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight into mitotic chromosome condensation in living human.....»»
Discovery of a hidden epigenetic clock in mitochondria reveals a "lifespan limit line"
Building on their work on epigenetics of aging and transposable elements, researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University have made another advance in understanding the molecular mechanisms of aging. Their latest st.....»»
From antiquity to adaptation: Tracing the genetic journey of east Asian chestnut varieties
Uncovering the genetic saga of Castanea trees, a study maps their evolutionary journey and local climate adaptations. This research reveals the genetic markers and molecular mechanisms that have allowed these nut fruit trees to adapt and flourish acr.....»»
Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
Deviations in particle interactions point to the existence of new bosons
Professors Andreas Crivellin of the University of Zurich and Bruce Mellado of the University of the Witwatersrand and iThemba LABS in South Africa have documented deviations in the way particles interact. These deviations are inconsistent in comparis.....»»
