Ode to Complementation

Posted Posted in Arts

By Angelica Degnan, Genetics ’15 Oh complementation testing whatever do you do? How does thee help me explain the mutants true? Begin with two recessive strains Cross, observe, unearth the ones that are the same What does this mean? How do you explain the ones that function redundantly through? Complementation, complementation alas I see the light That alleles that are […]

Photography: DNA

Posted Posted in Arts

By Riley Galton, Genetics ’14 Deoxyribonucleic acid, or DNA, encodes all of the instructions necessary for the beautiful figures and forms that can be found in the biological world. All plants, animals, and humans— subjects that are so familiar to the photographer—share the same underlying, four-letter genetic code. It is this simple molecular code that gives rise to the incredible […]

Arabidopsis – Model Organism

Posted Posted in Genetics

By John Tran,  Biochemistry & Molecular Biology ’14 Have you ever wanted to learn more about the plant model organism? Plants have many unique properties that make them especially important to all aspects of life. They provide oxygen, food, and energy, so you could imagine that there are many cellular and molecular processes that are involved in plants. For these […]

Population Vector

Posted 1 CommentPosted in Arts

By Jennifer Jahncke, Psychology ’14 Something we talk about a lot in neuroscience in terms of topics like visual perception and locomotion is population vectors. A population vector is the sum of each component vector. In this image, with the trees converging to a vanishing point, the population vector would be the vector in the center of the cluster (though not […]

When the Last Frog Croaks

Posted 1 CommentPosted in Environment

By Renata Vidovic, Evolution and Ecology ’15 To some, the phrase climate change evokes images of dry lakes, melting icebergs, and rising oceans. However, the effects of global warming are not simply cataclysmic geological changes. There are links between all biotic and abiotic features of an ecosystem. Unsurprisingly, climate change has an immense impact on frog populations around the world. […]

Mapping neurons through online gaming

Posted Posted in News, Technology

By: Jenny Cade, Biochemistry & Molecular Biology ‘15 One of the biggest challenges in neuroscience today is mapping the wiring of the nervous system. Looking at the spatial arrangement of neural networks can tell us a lot about how information is relayed, but accurate 3D mapping of neurons is an enormously challenging task, even with the aid of computer analysis. […]

Evolution of Tooth Enamel

Posted Posted in News

By Marisa Sanchez, Molecular and Cellular Biology, ‘15 One feature that sets humans apart from other primates is the thickness of tooth enamel. Scientists at Duke University have recently discovered evidence on how evolution has resulted in thickened enamel for human teeth. By comparing the human genome to five other primate species, geneticists and evolutionary anthropologists were able to identify […]

New Target For Alzheimer’s Treatment

Posted 1 CommentPosted in News

By David Ivanov, Biochemistry and Molecular Biology, ’15 A group of researchers studying brain cells have found a new potential target for pharmacological therapies that may help treat Alzheimer’s disease. Beta amyloid plaque, which appears to be a toxic build up of fragments of amyloid precursor protein (APP) in the brain, has long been associated with Alzheimer’s disease, and has […]

Is your spit making you fat?

Posted Posted in Genetics

One of the central pursuits of modern human genetics is to move beyond genomic correlation. That is, to demonstrate experimentally why a specific genetic variant may be associated with a disease. New work in Nature Genetics from an international team lead by Philippe Froguel at Imperial College in London does just this – demonstrating an interesting link between saliva and […]

Viral Evolution

Posted Posted in Genetics

By Mubasher Ahmed, Genetics ‘15 Viral evolution is an emerging field in biology that has great implications for human health. T7 is a phage virus, meaning it infects bacteria, and is a powerful model system in evolutionary virology. In a recent experiment, a team of biologists sought to understand the degree to which genetic elements engineered into the T7 phage […]
