Illuminating tissue formation through flourescence
Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders......»»
Exploring the centromere and its role in the formation of new species
Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers h.....»»
James Webb"s "too massive" galaxies may be even more massive
The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the universe. Various explanations have been proposed that may alle.....»»
Basic "toolkit" for organ development is illuminated by sea star
One of the most basic and crucial embryonic processes to unfold in virtually every living organism is the formation of hollow, tubular structures of various kinds. These tubes may form blood vessels or a digestive tract, and through branching and dif.....»»
A new nondestructive method for assessing bioengineered artificial tissues
Engineering organs to replace damaged hearts or kidneys in the human body may seem like something out of a sci-fi movie, but the building blocks for this technology are already in place. In the burgeoning field of tissue engineering, live cells grow.....»»
Researchers generate cattle blastoids in lab to aid farm animal reproduction
UT Southwestern Medical Center stem cell and developmental biologists and colleagues have developed a method to produce bovine blastoids, a crucial step in replicating embryo formation in the lab that could lead to the development of new reproductive.....»»
Engineers develop electroconductive hydrogel for biomedical applications
Synthetic hydrogels show great promise in tissue repair, drug delivery, medical implants and many other applications. Hydrogels functionalized with electrically conductive components can be used in bioelectronic devices for cardiac or neural interfac.....»»
How cells are influenced by their environment as tissues grow
How does an embryo develop? How do children grow, wounds heal or cancer spread? All of this has to do with the growth of body tissue. One of the major research interests of ETH Professor Viola Vogel and her senior assistant Mario C. Benn is to unders.....»»
How are dinosaur tissues preserved in deep time?
Ever since Mary Schweitzer found soft, stretchy tissue in a T. rex fossil in 2004, scientists have been trying to come to grips with how some biological tissues and cells could preserve within ancient critters......»»
Behind the formation and protection of microtubules
Cellular life hinges on a network of hollow cables called microtubules dynamically lengthening and shortening according to the needs of the moment. During cell division, for instance, these cables latch onto chromosomes and retract—yanking chromoso.....»»
Study suggests catalyst for human brain evolution
More than a million years ago, large chunks of the human genome were rearranged—a chance event during egg or sperm formation that led to the deletion, duplication, or reversal of sections of DNA. Those structural variants, researchers have now disc.....»»
From Arctic to Alps, icy exploration expands understanding of global warming
Microalgae in sediments signal what happened in the environment thousands of years ago, illuminating the range of future climate-change impacts......»»
Ultra-thin metal-organic layers prevent ice crystal formation in novel cryoprotectants
Small amounts of nanometer-thin metal-organic layers efficiently protect red blood cells during freezing and thawing, as a team of researchers writing in the journal Angewandte Chemie International Edition has discovered. The nanolayers, made from me.....»»
Leprosy-causing bacteria found in armadillo specimens highlight value of museum collections for tracking pathogens
Years-old tissue samples from armadillos in museum collections may harbor Mycobacterium leprae, the bacteria that causes Hansen's disease, also called leprosy, according to recent research my colleagues and I conducted......»»
Study reveals ERK activity is a molecular switch between scarring and tissue regeneration
Why do some animals regenerate lost tissues after injury while others don't? Researchers from the lab of Kerstin Bartscherer (Osnabrück University and formerly Hubrecht Institute) and Ashley Seifert (University of Kentucky) studied spiny mice, which.....»»
VIPER and T-Rex on double rocket launch
Not one, but two rocket launches with ESA-led experiments are flying to the edge of space just a week apart, providing unique data to researchers eager to learn more about fundamental physics, semiconductor production, the formation of planets and ho.....»»
Could quantum fluctuations in the early universe enhance the creation of massive galaxy clusters?
Astrophysicists have been trying to understand the formation of cosmological objects and phenomena in the universe for decades. Past theoretical studies suggest that quantum fluctuations in the early universe, known as primordial quantum diffusion, c.....»»
Researchers develop new method for layered structure detection in open star clusters
Morphological study of open clusters can provide observational evidence for tracing the formation mechanism of star clusters and help to explore the evolution of star clusters......»»
Condensed matter physics inspires a new model of cellular behavior
Cells are expert cooperators and collaborators. To maintain tissue health, cells talk to each other, exert pressure on each other, and kick out cells that are not contributing to the overall well-being of the collective. When it's time to get rid of.....»»
A dual symbiosis supports cuticle formation in wood-feeding beetles
Beetles usually rely on the help of bacterial partners to survive. These symbioses can have different functions. Bacterial symbionts may help digest plant material, make the beetles more resistant to plant defenses, or provide supplemental nutrients.....»»
Astronomers Spy a Giant Runaway Black Hole"s Starry Wake
A candidate “rogue” supermassive black hole may weigh as much as 20 million suns and has sparked a trail of star formation that is 200,000 light-years long.....»»
