BY ABBEY BIGLER Most of the mouthwatering dishes in a Thanksgiving feast share a vital ingredient: salt! Though the words “salt” and “sodium” are often used interchangeably, table salt is actually a compound combining the elements sodium and chloride. Table salt is the most common form that sodium takes on Earth. Many other sodium compounds...
by Johns Hopkins University School of Medicine Credit: CC0 Public Domain Johns Hopkins Medicine scientists have used glowing chemicals and other techniques to create a 3D map of the blood vessels and self-renewing “stem” cells that line and penetrate a mouse skull. The map provides precise locations of blood vessels and stem cells that scientists could...

Credit: DOI: 10.1016/j.ajpath.2021.07.009 For the first time, researchers at the University of Gothenburg have shown that metastases in patients with malignant melanoma gain access to the circulatory system not only through the outgrowth of new blood vessel branches, but also an alternative process in which one blood vessel divides into...
by University of California – San Diego This image, taken by confocal microscopy, shows a blood vessel. The protein actin, which helps make up the skeleton of a cell, is labeled in green. Thrombin, a pro-inflammatory mediator, causes gaps between blood vessel barrier cells. When the immune system is over-activated, as occurs in sepsis, blood vessels...
AUGUST 25TH, 2021 CONN HASTINGS A team at University of California San Diego invented a way to make steerable catheters that can more precisely navigate the tortuous architecture of the brain vasculature. The device was bioinspired by delicate structures found in nature, including flagella and insect legs, and uses principles from soft robotics to create a...
IMAGE: A SYNTHETIC HYDROGEL IN WHICH ENDOTHELIAL CELLS (PINK CELL NUCLEI) FORM NEW BLOOD VESSELS THAT GROW FROM A PARENT BLOOD VESSEL (UPRIGHT ON THE LEFT). THESE FORM CAVITIES CONNECTED TO THE PARENT VESSEL. HERE, THE VESSELS WERE PERFUSED WITH A LIQUID CONTAINING FLUORESCENT BEADS (YELLOW). THE BEADS FLOW INTO THE NEW VESSELS AT A...
by Max Planck Society A synthetic hydrogel in which endothelial cells (pink cell nuclei) form new blood vessels that grow from a parent blood vessel (upright on the left). These form cavities connected to the parent vessel. Here, the vessels were perfused with a liquid containing fluorescent beads (yellow). The beads flow into the new vessels...

by University of Seville Credit: Pixabay/CC0 Public Domain Researchers at the Biomedicine Institute of Seville (IBiS) have discovered a new mechanism of Alzheimer’s disease that disorganizes the blood vessels around amyloid plaques, one of the characteristic features of the disease. The study, published in the international journal Nature Communications, was led by the laboratory of Dr. Alberto Pascual,...
