Reef-building corals and microscopic algae within their cells evolve together
The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another's needs. A new study by Penn State biologists re.....»»

As EV sales slump, Volkswagen scales back battery factories buildout
VW might only need 170 GWh of cells in 2030 if demand stays depressed. Enlarge / A VW worker on the assembly line at Emden in Germany. (credit: Volkswagen) Volkswagen will wait to see what electric car demand is like be.....»»
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.....»»
Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's accretion disk, where infa.....»»
Australia tackles poor Great Barrier Reef water quality
Australia on Friday launched a multi-million dollar effort to stop pesticide runoff and other water quality issues on the Great Barrier Reef, the latest effort to save the ailing natural wonder......»»
The secret to sleepy cells" control of inflammatory secretions
Scientists at Sanford Burnham Prebys and the La Jolla Institute for Immunology have revealed a new secret regarding senescence, a cellular state similar to sleep that is more likely to affect aged cells. This drowsy condition is known to provide heal.....»»
Novel silica nonwoven fabric scaffold enhances understanding of cell-to-cell interactions
Communication and coordination among different cells are fundamental aspects that regulate many functions in our body. This process, known as paracrine signaling, involves the release of signaling molecules by a cell into its extracellular matrix (EC.....»»
Tissue fluidization during skin repair is crucial for wound healing, study reveals
The ability to repair tissue following injuries is essential for the survival of all animals. Following wounding, the skin is repaired by activating, migrating, and dividing skin stem cells. Defects of wound healing in humans lead to chronic wounds t.....»»
Surprising mechanism for removing dead cells identified
Billions of our cells die every day to make way for the growth of new ones. Most of these goners are cleaned up by phagocytes—mobile immune cells that migrate where needed to engulf problematic substances. But some dying or dead cells are consumed.....»»

"Amazon" algae shed light on what happens to populations when females switch to asexual reproduction
Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilized gametes and thrive without males. In a study published in Nature Ecology & Evolution, they use.....»»
New forensics technique measures individual DNA shedding to aid criminal investigations
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect's individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes......»»
Strategies for security leaders: Building a positive cybersecurity culture
Culture is a catalyst for security success. It can significantly reduce cybersecurity risks and boost cybersecurity resilience of any organization. Culture can also greatly enhance the perceived value, relevance and reputation of the cybersecurity fu.....»»
Animals with higher body temperatures are more likely to evolve into herbivores, study finds
A University of Arizona study has uncovered a surprising relationship between an animal's body temperature and its likelihood of evolving into an herbivore. The study, published in the journal Global Ecology and Biogeography, offers fresh insights in.....»»
Sea anemone study identifies potentially regenerative stem cells linked to conserved genes
The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the se.....»»
New method uses nanoparticles to reprogram exhausted immune cells
A novel study led by Prof. Mira Barda-Saad and her research team at the Goodman Faculty of Life Sciences at Bar-Ilan University has unveiled a novel method to rejuvenate natural killer (NK) cells in the fight against cancer. The study, published on t.....»»
Going slow is better for fast cycling: Study reveals unique replication fork behavior in pluripotent stem cells
Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report published in E.....»»
Morphable materials: Researchers coax nanoparticles to reconfigure themselves
A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, a.....»»
