I was in bio the other week and thinking about mitochondria (as you do) and I kept thinking about a heavy metal poster that was mitochondria and like

I did it lol

i am but a misfolded protein and every minor inconvenience i encounter is a ubiquitin, bringing me one step closer to the proteosome

Picture a world where computers can not only translate languages but also decipher biology’s convoluted language. This is the exciting frontier of Large Language Models (LLMs) that could transform our knowledge of genes and cells, which are the foundation of all life forms. Researchers from the Center, Chinese Academy of Sciences, China, explore this intriguing crossroad. Genes, which are passed down from one generation to another, hold the truths of our being. Cells, the tiny factories that keep us alive, execute these instructions coded in genes. Decoding how genes and cells interact helps to unravel health complications, diseases, and even mysteries regarding evolution.

Traditionally, scientists have used gene sequencing to study these intricate associations. But LLMs present an alternative way forward with immense promise. These models are trained using huge volumes of text data, enabling them to understand complicated patterns as well as mappings between them. Perhaps scientists can get a breakthrough by passing such datasets through LLMs.

All biological processes in our cells are constantly monitored to prevent the accumulation of defective proteins. In the worst case, such protein clumps can trigger diseases. The synthesis of new proteins is particularly susceptible to errors. Erronous proteins must then be removed by our cells. Until now, it was unclear how exactly this process works. Researchers led by F.-Ulrich Hartl at the MPIB now discovered a new mechanism that can initiate the targeted degradation of defective proteins. The protein GCN1 is of crucial importance in this process. The results have been published in the journal Cell.

Meet the unsung contributor to revolutionary breakthroughs in treating polio, cancer, HPV, and even COVID-19: Henrietta Lacks. Born in 1920 Roanoke, Virginia, Henrietta's mother Eliza died when she was only four, and she was ultimately raised by her maternal grandfather in Clover, Virginia. Henrietta worked as a tobacco farmer and attended a segregated school until the age of 14, when she gave birth to a son, Lawrence. A daughter, Elsie, was born three years later --to compound the family's difficulties, Elsie had cerebral palsy and epilepsy. Henrietta and her now-husband David Lacks moved to Turner Station (now Dundalk), Maryland where David had landed a job with a nearby steel plant. At the time Turner Station was one of the oldest African-American communities in Baltimore County and there was sufficient community support for the family to buy a house and produce three more children.

In 1951 at the age of 31, Henrietta died at Johns Hopkins Hospital of cervical cancer, mere months after the birth of the family's youngest son. But before her death --and without her or her family's consent-- during a biopsy two tumour cell samples were taken from Henrietta's cervix and sent to Johns Hopkins researchers. Hernietta's cells carried a unique trait: an ability to rapidly multiply, producing a new generation every 24 hours; a breakthrough that no other human cell had achieved. Prior to this discovery, only cells that had been transformed by viruses or genetic mutations carried such a characteristic. With the prospect of now being able to work with what amounted to the first-ever naturally-occurring immortal human cells, researchers created a patent on the HeLa cell line but hid the donor's true identity under a fake name: Helen Lane.

It is no exaggeration to state that in the 70 years since her death, Henrietta's cells have been bought, sold, packaged, and shipped by thousands of laboratories; with her cells being used as a baseline in as many as 74,000 different studies (including some Nobel Prize winners). Her cells have even been sent into space to study the effects of microgravity, and were instrumental in the Human Genome Project. While no actual law (or even a code of ethics) necessarily required doctors to ask permission before taking tissue from a terminal patient, there was a very clear Maryland state law on the books that forbade tissue removal from the dead without permission, throwing the situation into something of a legal grey area. However because Henrietta was poor, minimally educated, and Black, this standard was quietly (and easily) circumvented and she was never recognized for her monumental contributions to science and medicine ...and her family was never compensated. The family remained unaware of Henrietta's contribution until 1975, when the HeLa line's provenance finally became public. Henrietta had been buried in an unmarked grave in the family cemetery in Clover, Virginia but in 2010 a new headstone was donated and dedicated, acknowledging her phenomenal contribution. That same year the John Hopkins Institute for Clinical and Translational Research established a new Henrietta Lacks Memorial lecture series. A statue of Lacks was commissioned in 2022, to be erected in Lacks's birthplace of Roanoke, Virginia --pointedly replacing a previous statue of Confederate Gen. Robert E. Lee, which had been removed following nationwide protests over the murder of George Floyd.

Dive into The Immortal Life of Henrietta Lacks by Rebecca Skloot, originally published in 2011 and subsequently adapted into an HBO movie in 2017, starring Oprah Winfrey as Henrietta's daughter Deborah and Renee Elise Goldberry as Henrietta. (And yes, this book has been challenged and banned in more than one school district.)

Peer: How do you study for exams?

Me: …

definitely not by comparing everything to Ikémen Vampire so I remember it

i got to work with some HeLa cells today!

as cool of an experience as this was and as interesting as these things are, it’s always important to acknowledge the bad along with the good. Henrietta Lacks’ cells revolutionized so many areas of research, but she deserved so much better.

working with these cells today just really reminded me of the duality of many scientific developments. many things have come with great cost and harm and i think that’s something important to keep in mind.

if you aren’t familiar with the story of Henrietta Lacks, i highly recommend looking her up. there’s a book about her live (the immortal life of henrietta lacks) that’s very illuminating.

9/11~9/15

My nose has been in the books all week just studying cell and micro biology. The workload is finally starting to ramp up and I'm just trying to keep calm and figure out when's the best time to study.

I've been trying to figure out a new way to study biology since it's more diagrams-based compared to my previous classes, and I found this video on Instagram about using paper clips to secure flashcards to spiral notebooks. This is simply genius! Now I don't have to leave random blank spaces in my notes and can draw diagrams and mechanisms on the flashcard. And the best part is that I can flip it over and draw something else!
