Electric signals between individual cardiac cells regulate heartbeat
Researchers provide an update on how electrical impulses in the heart travel from cell to cell. The connections between cells forming the low resistance pathway and facilitating the current flow are called gap junctions. Each consists of many channel.....»»
Study proposes that proteins can compartmentalize and form droplets inside cells
In physics, a system composed of two substances can be modeled in accordance with classical mixture theory, which considers the fraction corresponding to each constituent and the interactions among constituents. Examples include the coexistence of hi.....»»
Plant stem cells: Understanding the biological mechanism of growth control
Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant growth in conjunction with WOX5. Understanding this mechanism is relevant for breeding more resilient or higher-yielding crops......»»
First ever visualization shows photoexcited charges traveling across the interface of two semiconductor materials
UC Santa Barbara researchers have achieved the first-ever "movie" of electric charges traveling across the interface of two different semiconductor materials. Using scanning ultrafast electron (SUEM) techniques developed in the Bolin Liao lab, the re.....»»
Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
Toss-up election leads some companies to delay investment decisions until after November
Some companies in the electric vehicle supply chain are waiting to see the results of the Nov. 5 presidential and congressional elections before making final decisions on investment plans......»»
From chaos to structure: How a bunch of seemingly disorganized cells go on to form a robust embryo
Pipetting liquids into tiny test tubes, analyzing huge datasets, poring over research publications—all these tasks are part of being a scientist. But breaking this routine is essential. Time away from the usual work environment can spark creative i.....»»
Spectroscopy study determines how catalysts remove dangerous nitrogen oxides
Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual.....»»
Assessment of damaged archaeological sites suggests they require individual protection concepts
An analysis of the damage to archaeological sites documented after a heavy rainfall event in July 2021 in parts of Germany shows that several factors increase the risk of damage to archaeological sites due to heavy rainfall and flooding events. For e.....»»
