Our great gamble as individuals composed of trillions of cells is that every cell is going to get along together and play by the rules. Our gut cells wake up and slay the nutrient uptake game every day, our retina cells are on top of processing incoming light, and even the humble cells in our […]

A Genetic Identity Crisis: Mosaicism in the Brain
posted by Joseph Herdy
We carry with us every day trillions of copies of one of the best stories ever written: the human genome. Carefully drafted and edited over 4 billion years, our genome contains all the information necessary, and then some, for making a human being from scratch. Often we think of this recipe book as a monolith: […]

Love in the Time of PCR

(Image credit: CellPress) Renowned geneticist George Church caused a stir last month with his idea for a brand new dating app, in which users submit their DNA for sequencing as a critical part of their profile. Church’s app, “digiD8”, doesn’t connect tech-savvy singles who love all-things-90’s, as the name implies, but rather matches users based […]
Can we inherit family trauma?

The epigenetics behind “generational trauma” [En español] The 23 and Me craze has officially reached my family. Both of my parents were born in Poland so the results weren’t a complete surprise, but as we watched the site track generations of family history from a single spit sample, new questions came up.

Genomic Imprinting: A Genetic Custody Dispute for Your Brain
posted by Joseph Herdy
During this holiday season, we would do well to reflect on what we’ve inherited from our parents. You might have your mother’s sense of humor but your father’s sense of direction. You and your Ma might share the same tastes in music, but you prefer your Pa’s tastes for ice cream. Although heavily influenced by […]

posted by Joydeep De
“J’ai peur du sommeil comme on a peur d’un grand trou, Tout plein de vague horreur…” In his phenomenal ‘Les fleurs du mal’ (‘Flowers of Evil’), Baudelaire promenades through the darkness of the night and with his characteristic gloomy brush, paints sleep as ‘a great hole’ that he fears. This myth surrounding sleep as a […]
Is evolution the missing link to understanding mental health?
posted by Nicole Mlynaryk
The human brain has been shaped over hundreds of thousands of years, with evolution selecting for traits that helped our species survive and thrive. So why do we still have so many genes that make us struggle? Why did our remarkable cognitive capacity come with such a susceptibility to disorder?
Uncle Syd and His Worms
posted by Joydeep De
[En español] Anybody, who does biological research using a model organism, especially those using an invertebrate, has quite invariably come across a certain prevalent hotchpotch of disbelief, cynicism and a reasonably uncomfortable amount of derision in the minds of their peers about the tiny creatures that they use to study biology. “So, these flies really […]
Immune to pain: new insights into chronic pain treatment
posted by Seraphina Solders
[En español] Jo Cameron, a Scottish woman in her mid-60s, was seemingly happy and healthy other than a problem with her hip. Now and then, it would give way and prevent her from walking straight. She had brought it up to her doctor, but because she wasn’t in pain, the issue was dismissed. It wasn’t […]
