Origin of endothelial cells constituting the vascular niche for hematopoietic stem and progenitor cells in zebrafish
Endothelial cells (ECs) line blood vessels and can serve as specialized vascular niches for hematopoietic stem and progenitor cells (HSPCs), a special environment where HSPCs reside and self-renew. A team of researchers found that endoderm-derived EC.....»»
Scientists study lipids cell by cell, making new cancer research possible
Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one......»»
Urgent need for logging loophole remedy within proposed Great Koala National Park
A team of conservation and policy researchers have called for a logging loophole within the proposed Great Koala National Park to be urgently remedied to stem the tide of harmful outcomes impacting the South East Australian koala population......»»
Researchers create artificial cells that act like living cells
In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells f.....»»
Pressure in the womb may influence facial development
Physical cues in the womb, and not just genetics, influence the normal development of neural crest cells, the embryonic stem cells that form facial features, finds a new study led by UCL researchers......»»
Diamond-based quantum sensing microscope offers effective approach for quantifying cellular forces
Cells rely on constant interplay and information exchange with their micro-environment to ensure their survival and perform biological functions. Hence, precise quantification of tiny cellular adhesion forces, spanning from piconewtons to a few nanon.....»»
Crucial building blocks of life on Earth can more easily form in outer space, says new research
The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals and biomolecules on the early Earth, eventually lea.....»»
Green mystery: Plumbian orthoclase reveals hidden resources
Plumbian orthoclase is a bit of a mystery, but this unique Aussie mineral is part of a mining industry revolution. The mineral's glowy green hue feels otherworldly. Although this Aussie kryptonite's origin is terrestrial, it's no less surprising......»»
Why zebrafish can regenerate damaged heart tissue, while other fish species cannot
A heart attack will leave a permanent scar on a human heart, yet other animals, including some fish and amphibians, can clear cardiac scar tissue and regrow damaged muscle as adults......»»
Light show in living cells: New method allows simultaneous fluorescent labeling of many proteins
Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge—especially in living cells, as the required fluorescent labeling had to be individually attached to each p.....»»
Key protein regulates immune response to viruses in mammal cells
Researchers have revealed the regulatory mechanism of a specific protein that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and.....»»
Transformers One trailer turns an origin story into a buddy comedy
The first trailer for the animated film Transformers One shows fans how Optimus Prime and Megatron used to be close friends on their home world of Cybertron......»»
Drawing a line back to the origin of life: Graphitization could provide simplicity scientists are looking for
Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible conditions for life's e.....»»
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......»»
From defects to order: Spontaneously emerging crystal arrangements in perovskite halides
Perovskites are among the most extensively studied materials in modern materials science. Their often unique and exotic properties, which stem from perovskite's peculiar crystal structure, could find revolutionary applications in various cutting-edge.....»»
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.....»»
Reproductive success improves after a single generation in the wild for descendants of some hatchery Chinook salmon
