Nanoparticle technology demonstrates selective destruction of leukemia cancer cells
A research team, affiliated with UNIST has developed nanoparticles that effectively treat acute myeloid leukemia (AML), offering the potential to reduce side effects while enhancing therapeutic efficacy by selectively targeting and eliminating leukem.....»»
Discovery of new bacterial toxins could be key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments for infections. These toxins, found in over 100,000 microbial genomes, can destroy the cells of bacteri.....»»
How Cells Resist the Pressure of the Deep Sea
Cell membranes from comb jellies reveal a new kind of adaptation to the deep sea: curvy lipids that conform to an ideal shape under pressure......»»
Deciphering the language of cells: How they sense and respond to mechanical forces
Cells, the fundamental building blocks of life, are constantly subjected to a variety of mechanical forces within our bodies. These forces, which can arise from both internal and external sources, play crucial roles in regulating cellular processes s.....»»
Team achieves successful reproduction of hematopoietic stem cell developmental process in an in vitro culture system
Researchers at Kumamoto University have achieved a notable advancement in stem cell biology by reproducing the developmental process of hematopoietic stem cells (HSCs) in vitro. This culture system not only enhances our understanding of how HSCs deve.....»»
Team develops promising new form of antibiotic that makes bacterial cells self-destruct
To address the global threat of antibiotic resistance, scientists are on the hunt for new ways to sneak past a bacterial cell's defense system. Taking what they learned from a previous study on cancer, researchers from the University of Toronto (U of.....»»
Uncovering new regulatory mechanisms in embryo implantation
Implantation is the initial step in pregnancy, where the embryo attaches to and enters the endometrium, the inner tissue layer of the uterus. During this process, the cells of the endometrium change to build the right conditions for the fertilized eg.....»»
Research provides molecular insights into sexual dimorphism of chicken feathers
Birds possess unique skin appendages called feathers that are derived from the outermost layer of skin cells. Feathers are important for several functions, such as flight, temperature regulation, protection from external stimuli, and mating behavior......»»
Fast super-resolved microscopy enables structured illumination and extended depth detection
Fluorescence microscopy is a powerful tool in biology, allowing researchers to visualize the intricate world of cells and tissues at a molecular level. While this technique has revolutionized our understanding of biological processes, imaging large a.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Biofabrication should be sustainable: Researcher calls for a rethink in current practices
Miriam Filippi, a researcher in the field of soft robotics working on developing bioinspired artificial muscle tissues, believes we can make human activities more ecologically sound by harnessing the power of living cells for bio-hybrid materials......»»
Protein signaling pathway provides insights into cell migration and cancer metastasis
The innate immune response is the body's first line of defense against infection, and a successful immune defense takes a village: a combination of physical barriers, chemical attacks, and an army of specialized white blood cells. But maintaining and.....»»
Android 15 is rolling out now, but the Galaxy S24 won’t get it until next year
This has been an unusual year for Android updates, as Google decided to launch the Pixel 9 phones in August rather than October. Google wanted … The post Android 15 is rolling out now, but the Galaxy S24 won’t get it until next year appea.....»»
Apple secretly tapped BYD for long-range EV battery tech, report says
Apple and BYD teamed up around 2017 to build a battery system using lithium iron phosphate cells, Bloomberg reported, signaling just how far the iPhone maker went in its efforts to produce a car......»»
