Catching Cancer: Blood Test for Early-Stage Diagnosis

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

Moon and Stars

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

Using your own DNA against you: Bio-control of coral reef pest might be possible

Crown-of-thorns starfish (COTS) are decimating coral populations along the Great Barrier Reef. Scientists have sequenced COTS genomes in the hopes of turning their own biology against them. Researchers think they have found the peptides the COTS use to communicate with each other. These peptides are released into the water to help the starfish aggregate before spawning events. If true, it’s possible to use these peptides to build several mechanisms for controlling the COTS pests. Continue reading Using your own DNA against you: Bio-control of coral reef pest might be possible

How Science and Genetics are Reshaping the Race Debate of the 21st Century

by Vivian Chou figures by Daniel Utter Donald Trump’s election as the 45th President of the United States has been marked by the brewing storms of racial conflicts. A rise in racial incidents ensued in the immediate aftermath of Trump’s victory in November 2016. Since the beginning of 2017, over 100 bomb threats have been made against Jewish community centers and schools. Trump’s travel ban, signed in … Continue reading How Science and Genetics are Reshaping the Race Debate of the 21st Century

Mosquitos: Friend or Foe? Possible use of mosquitos in modern epidemiology

With the warm weather of summer quickly approaching, a common enemy known as the mosquito will soon make a reappearance. Mosquitoes are more than just an irritation. In many areas of the world, mosquitoes are also carriers of infectious diseases such as malaria and the Zika virus. While the mosquito is a  major problem to many, scientists at Microsoft Research are attempting to exploit some … Continue reading Mosquitos: Friend or Foe?

Could Woolly Mammoths Walk Again?

The Church lab at Harvard University recently announced plans to create a hybrid mammoth and elephant. Using a technology called CRISPR, researchers in the Church lab have learned how to insert mammoth DNA into the cells of modern elephants. Theoretically, this could set the stage for developing an embryo with DNA from both a modern elephant and the woolly mammoth. The group would like to … Continue reading Could Woolly Mammoths Walk Again?
