Lipid droplets as endogenous intracellular microlenses
With the demand in real-time monitoring of endoplasmic variations and rapid detection of extracellular signals, a great number of approaches to bioimaging have been developed. The past few decades have witnessed a dramatic progress in optical imaging.....»»
New study solves mystery of how soft liquid droplets erode hard surfaces
A first-of-its-kind study led by University of Minnesota Twin Cities researchers reveals why liquid droplets have the ability to erode hard surfaces. The discovery could help engineers design better, more erosion-resistant materials......»»
Biochemical technique for finding small molecules discovered by researchers
Lipid rafts, a component of the plasma membranes that surround all cells in the human body, are essential in regulating the membranes' structure, among other functions. But they are hard to study because traditional biochemical methods tend to destro.....»»
Scientists uncover simple strategies for keeping foams on walls
Researchers from Tokyo Metropolitan University have uncovered a unique mechanism by which foams on walls drain and slip over time. They showed how a foam can lose liquid via "pinch-off," like droplets from a faucet, finding that the amount of liquid.....»»
When ribosomes collide: How bacteria clean up after molecular crashes
The knobby, 3D structure on the screen in front of Rachel Green showed an intracellular car wreck never before seen by scientists. It also confirmed a hypothesis a team in her lab had been working on for months......»»
Class II PI3K lipid kinase: Structure of novel antithrombotic drug target resolved
Phosphatidylinositol 3-kinase, or PI3K for short, is a family of lipid kinases that plays a key role in the human body, performing functions such as cell division, metabolism, and cell growth......»»
Scientist invents novel "WRAP" droplet manipulation method
Precise manipulation and transportation of micro-sized droplets is a challenging task, yet crucial for biomedical and industrial applications. A research team led by a scholar from the City University of Hong Kong (CityU) has successfully developed a.....»»
Have We Finally Found the Recipe for Making Rain?
An electric shock might be just the thing to persuade a cloud to produce some rain. New research suggests that supercharging a cloud could increase the attractive forces between droplets and help raindrops to grow. Have we finally found the recipe fo.....»»
Intracellular bacteria use sophisticated "hack" to evade a host"s immune system
Researchers at UC Davis have discovered a signaling mechanism that allows bacteria like Salmonella to evade destruction by the host's immune system......»»
Intracellular supramolecular self-assembly regulates cellular function
Supramolecular self-assembly based on noncovalent interactions is considered as a key strategy for introducing intracellular synthetic biocompatible macromolecules. The synthetic macromolecules resemble the nature, behavior, and function of biomacrom.....»»
New fluorescent nanovesicles for intracellular biomarker detection
A new work by the Nanomol Group, belonging to the CIBER-BBN network, together with a team from the University of Rome Tor Vergata, presents new nanovesicles capable of crossing biological barriers such as cell membranes, while maintaining their sensi.....»»
Visualizing intracellular nanostructures of living cells using nanoendoscopy-AFM
Atomic force microscopy (AFM) offers a method for label-free imaging of nanoscale biomolecular dynamics to solve biological questions that cannot be addressed via other bioimaging methods including fluorescence and scanning electron microscopy. Since.....»»
Coughing downward reduces spread of respiratory droplets: study
With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling such behavior in a variet.....»»
Large helium nanodroplets splash like water upon surface collisions
While working with helium nanodroplets, scientists at the Department of Ion Physics and Applied Physics led by Fabio Zappa and Paul Scheier have come across a surprising phenomenon: When the ultracold droplets hit a hard surface, they behave like dro.....»»
Lipid droplets as endogenous intracellular microlenses
With the demand in real-time monitoring of endoplasmic variations and rapid detection of extracellular signals, a great number of approaches to bioimaging have been developed. The past few decades have witnessed a dramatic progress in optical imaging.....»»
Your seat on public transportation determines level of exposure to exhaled droplets
The COVID-19 pandemic has revealed the urgency of understanding how public transportation ventilation systems transmit viruses and how exhaled droplets evolve in ventilated spaces. Researchers have wondered if those ventilation systems can be improve.....»»
Sneezes, rain clouds and ink jets: Improving the ability of optical microscopes to measure the volume of microdroplets
Sneezes, rain clouds, and ink jet printers: They all produce or contain liquid droplets so tiny it would take several billion of them to fill a liter bottle......»»
Can oil and water mix?
Common experience tells us that oil and water do not mix. Yet, it turns out that they can mix when oil is dispersed as small droplets in water. This strange behavior has long vexed scientists because there is no explanation for it. A team of EPFL and.....»»
Diverse genome sequences provide a powerful tool for studying risk of heart disease
In a large-scale study of people from diverse ancestries, researchers narrowed down the number of genomic variants that are strongly associated with blood lipid levels and generated a polygenic risk score to predict elevated low-density lipoprotein c.....»»
Tau and PQBP1: Protein interaction induces inflammation in the brain
Researchers have clarified the relationship between the intracellular receptor PQBP1 and the structural protein Tau, which is dysregulated in neurodegenerative diseases such as Alzheimer's disease. Tau was found to interact with PQBP1 in immune cells.....»»
How well do wet masks contain droplets?
Researchers modeled what happens to respiratory droplets when they come in contact with wet masks. Their results show that damp masks are still effective at stopping these droplets from escaping the mask and being atomized into smaller, easier-to-spr.....»»
