Lab mimics molecule found in poppies
An undergraduate leads the discovery of a way to synthesize a rare molecule drawn from poppies. The molecule could become a building block for painkillers and other drugs......»»
Hemoglobin acts as a chemosensory cue for mother mice to protect pups
Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier; when blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory sign.....»»
Hungry for love: Gut molecule discovered that flips the feeding-to-mating switch
On Valentine's Day, couples all over the world will enjoy romantic dinners to celebrate love and relationships. The association between nutrition and mating is not unique to humans but is reflected across species throughout the animal kingdom. Howeve.....»»
Single-molecule optofluidic microsensor with interface whispering gallery modes
Optical evanescent microsensors have attracted considerable research interests since they can detect unlabelled molecules and monitor their interactions in real time and in situ with ultrahigh sensitivity, fast response, and miniature footprint. Howe.....»»
New research could be the first step to hydrogen power, day and night
A new molecule could be the key to getting hydrogen whenever it's needed. Enlarge (credit: Aurich Lawson | Getty Images) There’s a disconnect between when people want to use electricity and when solar tends to produce it. Mo.....»»
Everyday Objects Can Run Artificial Intelligence Software
Slashdot reader sciencehabit quotes Science magazine: Imagine using any object around you—a frying pan, a glass paperweight—as the central processor in a neural network, a type of artificial intelligence that loosely mimics the brain to p.....»»
New atom-level insight into drug-target residence time
A new study from the University of Eastern Finland and the University of Tübingen helps to explain what defines how long a drug molecule stays bound to its target......»»
Taming of a shape-shifter molecule
Shape-shifter molecules are in never-ending motion. Their structure fluctuates because the carbon bonds that hold them together constantly break up and form again. Researchers have now found a way to "tame" a shape-shifter molecule called bullvalene......»»
A single molecule makes a big splash in the understanding of the two types of water
It plays a fundamental role in human existence and is a major component of our universe, yet there are still things we don't understand about water. To address the knowledge gaps, a collaborative team of Institute of Industrial Science, The Universit.....»»
Bacterial genome is regulated by an ancient molecule
We are all collections of cells, each cell containing the instructions—our DNA—to become any other cell. What differentiates a heart cell from a skin cell from a brain cell is the expression—or silencing—of genes......»»
Scientists Finally Solve the Mystery of Why Comets Glow Green
A team of chemists just solved the mystery of why comets' heads -- but not their tails -- glow green, which had puzzled researchers for decades. From a report: Studying an elusive molecule, which only fleetingly exists on Earth, was the key. Comets a.....»»
Gallic acid and stretching decrease osteoarthritis markers in cartilage cells
Researchers used gallic acid, an antioxidant found in gallnuts, green tea and other plants, and applied a stretching mechanism to human cartilage cells taken from arthritic knees that mimics the stretching that occurs when walking. The combination no.....»»
Detailed images of molecule associated with ALS could open door to therapies
Scientists have determined the structure of the molecule associated with amyotrophic lateral sclerosis (ALS) and multiple other neurodegenerative diseases. The researchers say this discovery could enable targeted development of new medical interventi.....»»
Research reveals how aging cells can be an underlying cause of kidney damage
A study in mice has found that stress and tissue damage initiated by angiotensin II, a molecule that is known to increase blood pressure and stiffening in the linings of blood vessels, leads to cellular senescence, a process by which a cell ages and.....»»
A deep learning model rapidly predicts the 3D shapes of drug-like molecules
In their quest to discover effective new medicines, scientists search for drug-like molecules that can attach to disease-causing proteins and change their functionality. It is crucial that they know the 3D shape of a molecule to understand how it wil.....»»
Plant pathogen evades immune system by targeting the microbiome
A team of biologists has identified that the pathogenic fungus Verticillium dahliae, responsible for wilt disease in many crops, secretes an 'effector' molecule to target the microbiome of plants to promote infection. The research was performed by th.....»»
Scientists use stem cells to create models of pre-embryos
Scientists are using human stem cells to create a structure that mimics a pre-embryo and can serve as a research alternative to a real one......»»
Modified protein from rattlesnake venom permits development of drug to modulate blood clotting
Researchers in Brazil and Belgium have developed a molecule of pharmaceutical interest from collinein-1, a protein found in rattlesnake venom. They used a technique called PEGylation to make the molecule, now called PEG-rCollinein-1, more stable in t.....»»
