Simulating the shear destruction of red blood cells
Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular stents, or interventi.....»»
Finely regulated luminescent Ag-In-Ga-S quantum dots with green-red dual emission toward white LEDs
Semiconductor quantum dots (QDs) materials have shown great potential for applications in lighting and display fields due to their wide color gamut, adjustable emission wavelength, high quantum efficiency, high color saturation, and low processing co.....»»
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......»»
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.....»»
Red milkweed beetle genome offers evolutionary insights into plant-insect interactions
Studying the secrets of how the common red milkweed beetle can safely feed on a toxic plant helps illuminate the ecological, evolutionary and economic impact of insect-plant interactions from a genomic perspective......»»
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.....»»
Yes, nature is complex—but saving our precious environment means finding ways to measure it
Nature loss directly threatens half the global economy. The rapid destruction of biodiversity should alarm the many Australian businesses dependent on nature, such as those in agriculture, tourism, construction and food manufacturing. Yet nature cons.....»»
Hurricane Milton tornadoes kill four in Florida amid rescue efforts
Hurricane Milton tore a coast-to-coast path of destruction across the US state of Florida, whipping up a spate of deadly tornadoes that left at least four people dead and millions without power Thursday......»»
Scientists track and analyze lofted embers that cause spot fires
In the chaos of a wildfire, heat, wind, flames and fuel interact to produce embers that are lofted into surrounding areas, starting new spot fires and spreading destruction and property loss in California's wildland-urban interface......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
Your doctor’s office could be reading your blood pressure all wrong
54 million US adults may be misdiagnosed with high BP based on bad readings. Many people may be surprised to learn the proper procedure for taking a blood pressure reading—becau.....»»
Cryo-electron microscopy provides new insights into the cell"s repair system
The membrane that surrounds cells in living organisms is extremely flexible and sensitive. How it protects itself from damage and renews itself is crucial for many life processes, and is not yet fully understood in detail. Scientists at Forschungszen.....»»
Nanopore technique shows transport mechanism of chaperone proteins at the single-molecule level
Proteins control most of the body's functions, and their malfunction can have severe consequences, such as neurodegenerative diseases or cancer. Therefore, cells have mechanisms in place to control protein quality......»»
New insights into bubble interference could enhance electrode design
Industrial electrochemical processes that use electrodes to produce fuels and chemical products are hampered by the formation of bubbles that block parts of the electrode surface, reducing the area available for the active reaction. Such blockage red.....»»
BreachLock Attack Surface Analytics strengthens enterprise CTEM capabilities
BreachLock strengthens continuous threat exposure management (CTEM) capabilities for enterprise customers with its new Attack Surface Analytics feature. Time is of the essence when Fortune 500 security teams find themselves waking up to a Code Red vu.....»»
Single-celled eukaryote employs unconventional cytoskeletal components for dynamic shape-shifting
Recently, a research group led by Prof. Miao Wei from the Institute of Hydrobiology (IHB) of the Chinese Academy of Sciences discovered that Lacrymaria cells utilize unconventional and novel components of the cytoskeleton to achieve their remarkable.....»»
