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.....»»
Flushing a public toilet? Don"t linger, because aerosolized droplets do
Flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet. A variety of pathogens are usually found in stagnant water as well as in urine, feces and vomit. W.....»»
Lipid research may help solve COVID-19 vaccine challenges
New research by University of Texas at Dallas scientists could help solve a major challenge in the deployment of certain COVID-19 vaccines worldwide—the need for the vaccines to be kept at below-freezing temperatures during transport and storage......»»
Unlocking richer intracellular recordings
Behind every heartbeat and brain signal is a massive orchestra of electrical activity. While current electrophysiology observation techniques have been mostly limited to extracellular recordings, a forward-thinking group of researchers from Carnegie.....»»
Curbing coronavirus spread in enclosed spaces means better masks, adequate ventilation
With research increasingly showing the COVID-19 virus is transmissible via smaller droplets suspended in air, there is a growing concern current public health guidelines of mask wearing and social distancing are insufficient in combating its spread i.....»»
"Climbing droplets" could lead to more efficient water harvesting
University of Texas at Dallas researchers have discovered that a novel surface they developed to harvest water from the air encourages tiny water droplets to move spontaneously into larger droplets......»»
Revealing the way a critical enzyme works in the cell
S-acylation is the process of chemically linking a lipid to protein via a thioester bond. It is an important process of the cell that regulates the localization and function of numerous proteins. It promotes lipid membrane association of the protein,.....»»
Life"s rich pattern: Researchers use sound to shape the future of printing
Researchers in the UK have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.....»»
BCAS3-C16orf70 complex is a new actor on the mammalian autophagic machinery
Autophagy is an intracellular degradation process of cytosolic materials and damaged organelles. Researchers at Ubiquitin Project of TMIMS have been studying the molecular mechanism of mitophagy, the selective autophagy process to eliminate damaged m.....»»
Scientists use lipid nanoparticles to precisely target gene editing to the liver
Scientists developed a highly efficient, targeted method for delivering gene editing machinery to specific tissues and organs, demonstrating the treatment of high cholesterol by targeting genes in the liver of mice, reducing cholesterol for over 3 mo.....»»
Scientists use lipid nanoparticles to precisely target gene editing to the liver
The genome editing technology CRISPR has emerged as a powerful new tool that can change the way we treat disease. The challenge when altering the genetics of our cells, however, is how to do it safely, effectively, and specifically targeted to the ge.....»»
On the line: Watching nanoparticles get in shape
Liquid structures—liquid droplets that maintain a specific shape—are useful for a variety of applications, from food processing to cosmetics, medicine, and even petroleum extraction, but researchers have yet to tap into these exciting new materia.....»»
Simply speaking while infected can potentially spread COVID-19
COVID-19 can spread from asymptomatic but infected people through small aerosol droplets in their exhaled breath. Most studies of the flow of exhaled air have focused on coughing or sneezing, which can send aerosols flying long distances......»»
Researchers find evidence of protein folding at site of intracellular droplets
Scientists have discovered the first evidence of protein folding driven by liquid-liquid phase separation, a phenomenon in which fluids form into microscopic droplets and separate inside cells—like drops of oil in water......»»
The search for electron-hole liquids gets warmer
An electron-hole liquid is a unique collective quantum state formation in semiconductors where free charges can condense into a droplet. These droplets have interesting uses for laser-controlled circuits based on light beams instead of wires. Unfortu.....»»
Exaggerated radar data above the freezing level induced by terrain
Meteorologists frequently study precipitation events using radar imagery generated at both ground level and from satellite data. Radar sends out electromagnetic waves that bounce off ice or water droplets suspended in the air. These waves quickly ret.....»»
Lipid epoxides target pain, inflammatory pathways in neurons
When modified using a process known as epoxidation, two naturally occurring lipids are converted into potent agents that target multiple cannabinoid receptors in neurons, interrupting pathways that promote pain and inflammation, researchers report. T.....»»
Porous materials unfavorable for coronavirus survival
As COVID-19 spreads via respiratory droplets, researchers have become increasingly interested in the drying of droplets on impermeable and porous surfaces. Surfaces that accelerate evaporation can decelerate the spread of the COVID-19 virus......»»
Droplets perform daredevil feats on gel surfaces
Welcome to the amazing world of soft substrates. These materials are made of silicon gels and have the same texture as panna cotta—but without the delicious flavor. They are used in a range of applications, especially in the pharmaceutical industry.....»»
Vibrating nanodroplets may invade a tumor
Sending tiny droplets to a tumor and having them vaporized using focused ultrasound: It could be a new way of tracing a tumor or deliver drugs locally. Researchers of the University of Twente now demonstrate a new phenomenon triggering droplet vapori.....»»
Lasing mechanism found in water droplets
Tiny molecular forces at the surface of water droplets can play a big role in laser output emissions. As the most fundamental matrix of life, water drives numerous essential biological activities, through interactions with biomolecules and organisms......»»
