Understanding the chemical communication between cells
Like the people they make up, cells communicate by bumping into one another and exchanging handshakes. Unlike people, cells perform these handshakes using the diverse range of sugar molecules coating their surface like trees covering a landscape. Han.....»»

Against the backdrop of the energy transition and the fight against climate change, a study published in the journal Angewandte Chemie International Edition offers a key to understanding how to improve the efficiency of processes that convert greenho.....»»
Nissan tech center volunteers cut loose after work: Wrenching, racing and learning
Doing hands-on mechanical work or driving an Acceleration Team vehicle in a race is more than just a way to have a little fun at work, team members say. It broadens their technical understanding of how cars work as well as how other teams within Niss.....»»
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.....»»
Understanding the relationship between food waste, climate change and an aging population
Producing food and getting it to people's plates entails a significant expenditure of energy and resources. Unfortunately, approximately one third of all food produced globally is not consumed and discarded. Hence, to build sustainable societies, it.....»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
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.....»»
All-optical switch device paves way for faster fiber-optic communication
Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must convert into electrical sign.....»»
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......»»
Key role of structural defects in amorphous solid deformation uncovered
Researchers at the Indian Institute of Science Education and Research (IISER) Pune and the CSIR-National Chemical Laboratory (NCL) Pune have shown that the macroscopic deformation of amorphous solids is controlled by structural defects within the mat.....»»
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.....»»
When hurricanes hit, online chatter can drown out safety messaging
When natural disasters strike, social networks like Facebook and X (formerly known as Twitter) can be powerful tools for public communication—but often, rescue workers and government officials struggle to make themselves heard above the general hub.....»»
New study reveals a global consensus on what democracy means
Most people in most countries state that they wish to have a democratic government. But the definition of democracy has been constantly contested. Without understanding what people really mean by democracy, the concept is vulnerable to being exploite.....»»
Discovery of key protein for biosynthesis of plant defense steroids could enhance pest control strategies
