Cornell Researchers Discover a New Mechanism of Cancer Chemotherapy Resistance
|
The Smolka Lab, led by Prof. Marcus Smolka, molecular biology and genetics, recently published a study shedding light on a novel pathway that explains how cancer cells can become resistant to chemotherapy and offering a promising mechanism to prevent chemo-resistance —the process by which cancer cells become tolerant to chemotherapeutic drugs.

LETTER TO THE EDITOR: Re: ‘What’s in Your DNA?’
|
To the Editor:
While the prospect of a “free” 23andMe DNA test might help to draw students to the biology department’s “Personal Genomics and Medicine” course, The Sun’s coverage of this attraction raises far more questions than answers. The March 25 article states that the course aims to “demystify genetics and genetic science.” I’d argue that currently available genetic tests like 23andMe actually do the opposite. Instead of simply revealing a genetic blueprint to the user, direct-to-consumer genetic tests are riddled with social, political and ethical questions, turning the results into more than objective “data.”
The article briefly raises the question of privacy, but this is not enough. How are these technologies regulated? Who owns the data, and what can they do with it?

What’s in Your DNA? Cornell Genomics Class Provides Students Free 23andMe Testing
|
The goal of the course and the option to participate in the 23andMe genetic testing is to help demystify genetics and genetic science, especially for students not majoring in scientific fields.

Student Spotlight on Iryna Dovirak ’20: Developing Wheat Resistant to the Effects of Climate Change
|
Because of the nutrient deficiency and the unique sensitivity of wheat to the bioavailability of copper, Dovirak decided to focus on better understanding and further improving the process of copper absorption, regulation and transport in grains.

Gene in Worms Could Be Key to Longer Human Lifespan
|
Popular legend claims that drinking from the fountain of youth will keep one’s body vigorous and vivacious for years to come. Prof. Sylvia Lee, molecular biology and genetics, may have discovered such an elixir in the soils of Ithaca. Her research indicates the secret of immortality may be hidden in the genome of a worm. Lee found that Caenorhabditis elegans, a common species of soil worm, has a very similar lifespan and reproductive pattern to humans, importantly sharing hallmark features of human aging. These similarities make C. elegans a premier experimental model to reveal the mysterious mechanisms of mortality in humans.
