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.....»»
Titanium oxide nanotubes facilitate low-cost laser-assisted photoporation
A research team at the Department of Mechanical Engineering at Toyohashi University of Technology developed a nanosecond pulse laser-assisted photoporation method using titanium-oxide nanotubes (TNT) for highly efficient and low-cost intracellular de.....»»
How cells "eat" their own fluid components
Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling. Recent research has revealed that phase separated droplets have a range of important funct.....»»
How drain flies dodge a washout
The survival of pesky little flies in showers and other wet areas around the house, impervious to water droplets that may be larger than they are, comes down to more than quick reflexes. The insects have evolved a unique coating of hairs that allows.....»»
New mathematical model: How dangerous bacteria form colonies
It can be observed every time you take a shower: Small droplets of water join together to form larger and larger drops—until they are so heavy that they run down the wall. Scientists call this daily-life phenomenon coalescence—which surprisingly.....»»
Researchers identify nanoparticles that could deliver therapeutic mRNA before birth
Researchers at Children's Hospital of Philadelphia and the School of Engineering and Applied Science at the University of Pennsylvania have identified ionizable lipid nanoparticles that could be used to deliver mRNA as part of fetal therapy. The proo.....»»
A Newfound Source of Cellular Order in the Chemistry of Life
Inside cells, droplets called condensates merge, divide, and dissolve. Their dance may regulate vital processes......»»
Masks block 99.9% of large COVID-linked droplets: study
Face masks reduce the risk of spreading large COVID-linked droplets when speaking or coughing by up to 99.9 percent, according to a lab experiment with mechanical mannequins and human subjects, researchers said Wednesday......»»
Electro-sprayed micro-droplets help kill bacteria and viruses
With COVID-19 raging around the globe, researchers are doubling down on methods for developing diverse antimicrobial technologies that could be effective in killing a virus, but harmless to humans and the environment......»»
Sound waves spin droplets to concentrate, separate nanoparticles
Mechanical engineers at Duke University have devised a method for spinning individual droplets of liquid to concentrate and separate nanoparticles for biomedical purposes. The technique is much more efficient than traditional centrifuge approaches, w.....»»
Scientists create a new phototoxic protein, SuperNova2
Scientists from Skoltech, the Institute of Bioorganic Chemistry of RAS and the London Institute of Medical Sciences (LMS) have developed an enhanced version of SuperNova, a genetically encoded phototoxic synthesizer, that helps control intracellular.....»»
How do pathogens sense environment? Scientists identify key proteins" structures
In order to adapt to the changing environment, bacteria must quickly transform extracellular information into appropriate intracellular reactions. Two component system (TCS) is the main signal transduction protein in prokaryotic cells to transform en.....»»
A genetic control of stem cell differentiation and organ maintenance by induction of fat metabolism
Fat metabolism (lipid metabolism) is the term used to describe the synthesis and degradation of lipids in cells. This is increasingly recognized as an important key process that could also influence the maintenance and differentiation of stem cells......»»
