Ongoing genome doubling shapes evolvability and immunity in ovarian cancer - Nature A single-cell sequencing study using more than 30,000 tumour genomes from human ovarian cancers shows that whole-genome doubling is an ongoing mutational process that drives tumour evolution and disru...

A cartoon titled ‘The Life of a Scientist’. (The life is depicted as a set of steps, three up then three down with a character on each) Baby: Such a mysterious world! Child: I must search for answers Young adult: Each answer leads me to more questions Middle age: ... At least I've got lots of questions Old age: Ok, I guess questions are my thing now From grave: Such a mysterious world!

Academia isn’t perfect, but it offers a rare space to pursue knowledge for its own sake. If research were fully privatized, only profit-driven questions would get asked. Yet many of the most transformative discoveries began as curiosity-driven inquiries whose value wasn’t clear for years.

Science Advances’ special issue on women’s health highlights a growing wave of research focusing on women’s unique biological and psychological experiences. Articles cover a range of studies from the interplay between menopause and Alzheimer’s risk to the menstrual cycle’s influence on the brain-heart connection. It also describes the opportunities pregnancy provides to research aspects of both physical and mental health. By prioritizing women’s unique physiological and psychological experiences, research can expand the frontiers of knowledge in ways that benefit everyone.

Immunogenomic cancer evolution: A framework to understand cancer immunosuppression Understanding the impacts of genetic abnormalities on immune responses to tumors can inform immunogenomic-based precision medicine.

A new #ScienceImmunology Review suggests that genomic changes in cancer cells can shape antitumor immune cells and facilitate immunogenomic cancer evolution, which could inform future strategies for precision medicine. scim.ag/3FS4PZP

The end of the genetic paradigm of cancer Genome sequencing results and single-cell transcriptomics continue to produce findings that challenge the idea that cancer is purely a ‘genetic disease’. This Essay delves into cancer omics data that ...

Provocative but important commentary from Sui Huang & co

Argues we need to change the paradigm of cancer origin from a somatic mutation theory to one grounded in gene regulatory networks & tissue organisation: a system level rather purely genetic mechanism

Researchers uncover what drives aggressive bone cancer Study identifies a novel mechanism driving osteosarcoma and provides insights to help predict patient outcomes.

Osteosarcoma, an aggressive bone cancer, most commonly affects children and young adults.

New research solves the mystery of what drives the genomic rearrangements causing the aggressive development and evolution of osteosarcoma tumours.

Inherited genome instability Germline structural variants are a risk factor for pediatric extracranial solid tumors

Want to know how inherited genome instability contributes to childhood cancers? Checkout this perspective from Jayne Hehir-Kwa and me www.science.org/doi/10.1126/... on the latest brilliant work from @vanallenlab.bsky.social www.science.org/doi/10.1126/... on rare germline SVs in paediatric cancers

The concept of peer review is correct, but the execution is flawed and creating a broken system: Not enough well compensated editors, each under-experienced and overloaded. They lack the time and training to decide which papers to send out to review and which wasteful reviewer requests to overide

This is a great post from @gangfang.bsky.social on the use of Oxford Nanopore (or PacBio) technologies for DNA modification detection.
The conclusions are that Oxford Nanopore works well for 5mC in most mammalian tissues where it is expected to be the majority modification in CpG context, but
