Grass-fed or grain-fed?
By Jenny Cade, Biochemistry & Molecular Biology ’15 Eating grass-fed beef and pasture-raised chicken is the eco-friendly thing to do–right? Maybe not, according to a recent paper published in the Proceedings in the National Academy of Science. The study proposes that intensifying livestock production by transitioning from pure grazing to mixed systems–where animals are fed […]
Stop Looking for the Drug. Look at the Genes – Bulletproof Anti-doping Test
By Isra Uz-Zaman, Genetics ’14 Cheating in sports in not a new phenomenon. In the modern era, numerous athletes participate in blood doping by injecting erythropoietin (EPO) into their blood to increase the amount of red blood cells and thus improve their athletic performance. EPO is a protein hormone produced by the kidney which stimulates […]
New Method Increases Supply of Embryonic Stem Cells
By: Varsha Prasad, Genetics ’15 A study to employ a new method of generating human embryonic stem cells without destroying any human embryos is currently being conducted by an international research team led by Karl Tryggvason, Professor Medical Chemistry at Karolinska Institutet and a Professor at Duke-NUS Graduate Medical School in Singapore. The researchers developed […]
Engineering Hepatitis Virus-like Particles for Oral Vaccine Delivery
By David Ivanov, Biochemistry ’15 Oral vaccines are known to be a convenient and effective method for treatment or prevention of diseases caused by pathogenic microorganisms. The difficulty of developing such vaccines is due to the often inhospitable environment of the stomach and intestinal tract because of low pH, or acidity, as well as enzymes […]
Climate Engineering: Worth the Risk?
By Ashley Chang, Genetics ’15 Researchers at the GEOMAR Helmhotltz Centre for Ocean Research Kiel are studying the long-term effects of “climate engineering” methods that could help to preserve the climate and protect from rising temperatures. This winter every part of the world except the eastern United States reported record breaking high temperatures. Although political […]
Genome-Wide Association Identifies Genes Linked to Autism
By Ashley Chang, Genetics ’15 Biostatisticians led by Knut Wittkowski at Rockefeller University Hospital have employed new methods of genome-wide association studies to identify genes that they believe to be associated with autism. The researchers compared genomes of patients with varying degrees of autism to healthy patients and were able to identify genetic variations that […]
