Glioblastoma is one of the most deadly brain cancers because it is nearly impossible to destroy the cause of the cancer: cancerous stem cells. However, scientists are using Zika’s preference for stem cells to target and eliminate the cancerous stem cells in adults. The preliminary study shows the viability of this method, but more thorough research and a PR campaign may be necessary before Zika treatments for brain cancer can become standard protocol. Continue reading Could Zika become a treatment for brain cancer?
3D printing is poised to become a major technological advancement in treating injuries and illnesses that cause tissue damage. For scientists, creating artificial tissue with 3D printing has been a challenge. As the 3D printed structure grows in size, cells often move and compromise the tissue’s structural integrity. New work from Oxford University addresses this problem. By encasing cells in nanoliter sized droplets of fat molecules, researchers are able … Continue reading Scientists Learn to 3D Print Cells One Drop at A Time
What is the difference between a normal cell and a cancer cell? The answer lies in their DNA. Cancer results from the accumulation of genetic mutations, which trigger uncontrolled cell growth. Cancer’s mutated DNA can reveal its presence early on in the disease. Like leaving fingerprints at a crime scene, tumor cells release small pieces of DNA into the bloodstream. This “circulating tumor DNA” can now … Continue reading Catching Cancer: Blood Test for Early-Stage Diagnosis
If you look closely at this zebrafish embryo, you will notice bright spots that look like stars covering the entire body. The nuclei of each cell in this embryo has been labeled with a fluorescent protein so when you look at the nuclei under a microscope, they are resplendent. By labeling each individual nuclei, we can visualize changes occurring in each cell throughout development of … Continue reading Moon and Stars
There are a multitude of signals that elegantly orchestrate the proper development of the heart. In this image of a 3-day-old zebrafish heart, the signal that is localized to the developing atrio-ventricular valve and smooth muscle is labeled in green using green fluorescent protein (GFP). This particular signal is important for the formation of the cardiac valves, which will allow blood to pass from the … Continue reading Cross-section of the Developing Zebrafish Heart
AquaBounty, a Massachusetts-based company, began growing genetically modified (GM) salmon nearly three decades ago. However, it wasn’t until 2015 that the FDA approved the fish for human consumption. Health Canada made the same decision in 2016. While a current law prevents US sales until a labeling system is established, Canada has imported roughly 5 tons of the GM salmon since May 2016. Although the fish sell unlabeled, Canadians appear to be embracing the next frontier in aquaculture. Continue reading Canadians bringing genetically modified salmon to their tables
Thierry Work and a team of wildlife disease researchers are manufacturing reptile skin in the hopes of saving endangered turtles. A virus, ChHV5, has been infecting endangered green sea turtles, causing tumors to grown on the their skin and inside their bodies. The infection eventually weakens the immune system, and leads to death. Studying this virus proved incredibly difficult. Traditional methods of growing viruses to study ChHV5 in the lab … Continue reading Scientists Grow Turtle Skin to Study New Virus
