This suggest that telomere maintenance in sperm is more robust than in oocytes and impacts the inherited telomeres. Full paper is below. Curious to know what you think as this is a new area for us!

Long-read sequencing reveals telomere inheritance patterns from human trios

Telomeres are essential for maintaining genomic integrity and are associated with cellular aging and disease, yet the factors influencing their inheritance across generations remain poorly understood....

Congratulations! Beautiful work and confirming once again the curious paternal age effect on telomere length.

Sperm sequencing reveals extensive positive selection in the male germline - Nature

A combination of whole-genome NanoSeq with deep whole-exome and targeted NanoSeq is used to accurately characterize mutation rates and genes under positive selection in sperm cells.

"For too long, we have outsourced how we define prestige to the indexers and specifically the impact factor. This has created a system in which the need to get published in prestigious journals creates bad incentives for authors to inflate their findings to tell a good story."

Putting knowledge before prestige | Laboratory News

Our reliance upon the impact factor is destroying public trust in science, argues Damian Pattinson.

I would remiss if I didn't have a whoop about Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi winning the Nobel Prize in Physiology or Medicine for discovering immune cells — regulatory T cells — that help to prevent the body from attacking its own tissues

Medicine Nobel goes to scientists who revealed secrets of immune system ‘regulation’

Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi discovered cells that protect the body from autoimmune diseases.

Também Miguel Duarte foi detido, juntamente c Mariana Mortágua e Sofia Aparício. Hoje vai haver manifestação em Lisboa, à frente da Embaixada de Israel, às 18h. A pressão internacional é fundamental para protegermos todos os tripulantes da flotilha e o Governo português deve condenar esta detenção.

In food history, we notice how super-refined foods--gelatin, vienna sausage, white bread--lose class and become horrifying once they become industrialized. Suddenly, fingermarks in bread dough demonstrate skill, not clumsiness.

Post-chatGPT, I'm feeling this about writing. Smoothness feels gross.
