Patterns in primordial germ cell migration
Whenever an organism develops and forms organs, a tumor creates metastases or the immune system becomes active in inflammation, cells migrate within the body. As they do, they interact with surrounding tissues which influence their function. The migr.....»»

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.....»»
"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.....»»
Proof-of-concept study demonstrates mid-infrared computational temporal ghost imaging
Ghost imaging in the time domain allows for reconstructing fast temporal objects using a slow photodetector. The technique involves correlating random or pre-programmed probing temporal intensity patterns with the integrated signal measured after mod.....»»
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.....»»
Microscopic fossilized shells reveal ancient climate change patterns
At the end of the Paleocene and beginning of the Eocene epochs, between 59 to 51 million years ago, Earth experienced dramatic warming periods, both gradual periods stretching millions of years and sudden warming events known as hyperthermals......»»
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.....»»
Schools are competing with cell phones. Here"s how they think they could win
Isabella Pires first noticed what she calls the "gradual apathy pandemic" in eighth grade. Only a handful of classmates registered for service projects she helped organize at her Massachusetts school. Even fewer actually showed up......»»
The promise of synthetic cells
For over a decade, scientists have made extraordinary progress on the long-held dream of fabricating an entire cell from nonliving molecules and materials......»»
Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poor.....»»
