A new study finds the clusters form small, stable droplets and may give the genome a gel-like structure. A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that’s not all that’s tucked away in there. The nucleus is also home to small bodies called nucleoli — clusters … Continue reading How Molecular Clusters in the Nucleus Interact With Chromosomes? (Biology)
Our DNA is very similar to that of the chimpanzee, which in evolutionary terms is our closest living relative. Stem cell researchers at Lund University in Sweden have now found a previously overlooked part of our DNA, so-called non-coded DNA, that appears to contribute to a difference which, despite all our similarities, may explain why … Continue reading What Makes Us Human? The Answer May be Found in Overlooked DNA (Biology)
James Buchanan “Bucky’’ Barnes is a fictional superhero/supervillain character in the Marvel Cinematic Universe (MCU). Also known as the Winter Soldier, he is able to withstand the biological impairment of cryogenic freezing. But how? Well, Ilja Voets and colleagues now answered this question. Following his super-soldier experimentation, they suggested that, the Winter Soldier’s DNA has … Continue reading How Winter Soldier Could Be Able To Withstand Freezing Temperatures? (Superhero / Biology)
Abnormal cells that go on develop into oesophageal cancer – cancer that affects the tube connecting the mouth and stomach – start life as cells of the stomach, according to scientists at the University of Cambridge. The study, published today in Science, found that a particular subtype of oesophageal cancer known as oesophageal adenocarcinoma is always … Continue reading Discovery of Origin of Oesophageal Cancer Cells Highlights Importance of Screening For Pre-cancerous Barrett’s Oesophagus (Biology)
Researchers have known from several lines of evidence that the ancient hominins known as the Denisovans interbred with modern humans in the distant past. Now researchers reporting in the journal Current Biology on August 12 have discovered that the Philippine Negrito ethnic group known as the Ayta Magbukon have the highest level of Denisovan ancestry in the … Continue reading People in the Philippines have the most Denisovan DNA (Biology)
Researchers from the University of Southern California, Merck & Co., Skoltech, MIPT, UCLA, and the Université de Sherbrooke have determined the structure of the human leukotriene B4 receptor 1, involved in inflammatory, infectious, allergic, and tumorigenic diseases. Published in Nature Communications, the analysis of the structure reveals how the receptor recognizes its binding partners and interacts with them. This opens up … Continue reading Study Reveals Structure Of Receptor Implicated In Type 2 Diabetes And More (Biology)
Cornell researchers have identified a new way to measure DNA torsional stiffness – how much resistance the helix offers when twisted – information that can potentially shed light on how cells work. Understanding DNA is critically important: It stores the information that drives how cells work and is increasingly being used in nano- and biotechnology … Continue reading New Technique Illuminates DNA Helix (Biology)
Peer into any fishbowl, and you’ll see that pet goldfish and guppies have nimble fins. With a few flicks of these appendages, aquarium swimmers can turn in circles, dive deep down or even bob to the surface. New research led by the University of Colorado Boulder has uncovered the engineering secrets behind what makes fish … Continue reading Engineers Uncover the Secrets of Fish Fins (Biology)
A two-arm molecule can effectively deplete cancer-protecting cells inside tumors, allowing the immune system to fight off tumors without becoming overactive. The finding, published online in Science Translational Medicine, could lead to new types of cancer immunotherapies. “By effectively removing these immune-suppressive cells inside tumors instead of in the whole body, the immune system can attack cancers … Continue reading Increasing The Immune System’s Appetite For Cancer Protectors (Biology)
