The eukaryotic cell nucleus resembles the layout of a superstore
The headquarter of a eukaryotic cell is the nucleus, and most of the cell's information and instructions are stored there in the form of DNA (Deoxyribonucleic acid). The DNA, which is twisted, rolled and bundled in a two-meter-long chain, together wi.....»»

Human mouth bacteria reproduce through rare form of cell division, research reveals
One of the most diverse ecosystems on the planet is closer than you think—right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in distinct, structured communities called biofilms. Nearly.....»»
AI tool maps out cell metabolism with precision
Understanding how cells process nutrients and produce energy—collectively known as metabolism—is essential in biology. Modern biology generates large datasets on various cellular activities, but integrating and analyzing the vast amounts of data.....»»
Light-activated polymerization methods unlock new possibilities for intracellular applications
Synthetic polymers play a crucial role in cell biology, serving as delivery vehicles for DNA and drugs, acting as fluorescent probes for cellular sensing, functioning as bioinks for tissue engineering, and mimicking biological functionality (e.g., ar.....»»
Scientists modify citrus pectin with induced electric field
Pectin, a natural and nontoxic acidic polysaccharide, is widely found in the primary cell wall and inner layer of terrestrial higher plants. The main domains of pectin are homogalacturonan and rhamnogalacturonan I, which contribute to the complexity.....»»
New knowledge about cell receptors paves the way for future drugs against intestinal tumors
A new study from Karolinska Institutet published in Nature Communications provides valuable insights into the activation of receptors on the cell surface. The knowledge could lead to new targeted therapies and drugs against intestinal tumors, among o.....»»
Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
"Silent" mutations found to have repercussions beyond their own gene
Genetic disorders—like cystic fibrosis and Huntington's disease—are considered incurable, with gene mutations occurring in essentially every cell of the body. Gene mutations occur when one nucleotide in a codon is switched. In non-synonymous muta.....»»
Light microscopy study reveals molecular density changes during mitotic chromosome condensation
A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight into mitotic chromosome condensation in living human.....»»
Discovery explains the chemistry behind the cell"s energy molecule
An international research team led by Professor Magnus Wolf-Watz at Umeå University has discovered how the magnesium atom directs the chemistry that catalyzes the production of the energy molecule ATP in a cell. The study is published in the journal.....»»
Toyota, BMW to upgrade fuel cell alliance, report says
BMW and Toyota plan to sign a memorandum of understanding for the partnership next week, with an official announcement set for Sept. 5, Nikkei Asia reported......»»
Dissecting caspase-2-mediated cell death: From intrinsic PIDDosome activation to chemical modulation
Caspase-2, an initiator caspase, plays a critical role in programmed cell death in response to certain cellular stresses. Its activation is facilitated by the PIDDosome, a multi-protein complex that assembles under conditions of genotoxic stress. Des.....»»
Study reveals bioactive power of a natural spearmint compound against weeds
A recent study reveals the natural compound (-)-carvone in spearmint as a potent and sustainable alternative to chemical herbicides. This research demonstrates how (-)-carvone targets and degrades microtubules in weeds, inducing cell death and inhibi.....»»
Researchers investigate cell-free DNA as early sepsis marker in foals
It's hard to be a horse. It's especially hard to be a newborn foal, dropped into a world of microbes and bacteria with your sole initial defense against devastating infections being the antibodies you get from your mother's milk, or colostrum. Resear.....»»
Tomato ripening study highlights cell wall component interactions
Tomato fruit ripening involves intricate biochemical and structural changes, particularly within the cell wall, which are vital for the fruit's final texture and quality. These changes include modifications in polysaccharides and proteins, but the sp.....»»
Mapping the sex life of malaria parasites at single cell resolution reveals genetics underlying transmission
Malaria is caused by a eukaryotic microbe of the Plasmodium genus, and is responsible for more deaths than all other parasitic diseases combined. In order to transmit from the human host to the mosquito vector, the parasite has to differentiate into.....»»
