Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
Saturn"s ocean moon Enceladus could support life—researchers are working out how to detect extraterrestrial cells there
Saturn has 146 confirmed moons—more than any other planet in the solar system—but one called Enceladus stands out. It appears to have the ingredients for life......»»
Computer model suggests frozen cells could be used to save northern white rhino from extinction
A team of geneticists and computer scientists from the San Diego Zoo Wildlife Alliance, Cornell University and the University of California, Santa Cruz, has created a computer model that shows it should be possible to save the northern white rhino fr.....»»
Researchers uncover human DNA repair by nuclear metamorphosis
Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging......»»
Nanoparticle delivery of FZD4 to lung endothelial cells inhibits lung cancer progression and metastases
A recent study from the lab of Tanya Kalin, MD, Ph.D., professor of Child Health and Internal Medicine at the University of Arizona College of Medicine—Phoenix, has shown potential to improve therapeutic outcomes for patients suffering from lung ca.....»»
Scientists develop framework to measure plastic emissions and bolster U.N. efforts to reduce pollution
University of Toronto (U of T) scientists have developed a framework for measuring plastic pollution emissions akin to the global standard for measuring greenhouse gas emissions. The researchers say the approach will boost identification of the bigge.....»»
Future Apple Vision Pro could help the user get life-saving medical advice
Apple is developing technology for wearable devices like Apple Vision Pro that measure and monitor biometric data and location to provide tailored and potentially lifesaving advice.Apple wearables could provide medication reminders and guidance. An A.....»»
Researchers find cryptic genetic element in the human gut that could serve as a sensitive biomarker
A component of the human intestinal flora that has been little studied to date is the focus of a new study from Germany. Plasmids are small extrachromosomal genetic elements that frequently occur in bacterial cells and can influence microbial lifesty.....»»
Nanovials method for immune cell screening uncovers receptors that target prostate cancer
A recent UCLA study demonstrates a new process for screening T cells, part of the body's natural defenses, for characteristics vital to the success of cell-based treatments. The method filters T cells based on the receptor proteins found on their sur.....»»
Discovery of organic catalyst could lead to cheaper fuel cells
With atmospheric carbon dioxide at record highs, the search for clean-energy alternatives to the use of fossil fuels is growing increasingly urgent......»»
A rechargeable nanotorch: Afterglow luminescence imaging tracks cell-based microrobots in real time
An afterglow luminescent nanoprobe opens up new possibilities for imaging living cells. As a research team reports in the journal Angewandte Chemie International Edition, their new "nanotorch" can continue to luminesce for more than 10 days after a s.....»»
New study details how starving cells hijack protein transport stations
A new study details how nutrient-starved cells divert protein transport stations to cellular recycling centers to be broken down, highlighting a novel approach cells use to deal with stressful conditions......»»
Decoding the language of cells: Profiling the proteins behind cellular organelle communication
In cellular biology, unraveling the complexities of cellular function at the molecular level remains a paramount endeavor. Significant scientific focus has been placed on understanding the interactions at organelle contact sites, especially between m.....»»
Traces of DNA in the stomachs of predatory snails provide new insights into the ecology of placozoans
Placozoans are among the simplest animals and occur worldwide in coastal waters. It was previously assumed that the tiny creatures, which measure just a few millimeters, live either on hard surfaces—such as rocks, corals, and mangrove roots—or fl.....»»
New study finds potential targets at chromosome ends for degenerative disease prevention
We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during c.....»»
Study proposes large-scale biomanufacturing workflow to produce natural killer cells and extracellular vesicles
A team of uOttawa Faculty of Medicine researchers have developed a path to a biomanufacturing process that could potentially transform how Canada generates immunotherapeutic materials—specifically natural killer cells and extracellular vesicles (EV.....»»
Researchers find a new organelle evolving
