What’s been going on in the life sciences world this week? Check out Week in Brief for an overview of the biggest news from the last seven days.
Genomics visionary J. Craig Venter passed away aged 79 this week. A pioneering force in modern genomics, Dr. Venter played a central role in accelerating the progress and competitive momentum of the Human Genome Project. We were deeply saddened to hear of his passing, and our thoughts are with his loved ones at this time.
Researchers have shown that evolution has repeatedly drawn on the same set of genes for over 120 million years to shape how animals develop. By analysing genomes across multiple species, the team found that rather than creating entirely new genes, evolution frequently modifies existing ones to generate new biological features and functions.
A study has suggested that obesity is a driver of rising cancer cases in individuals aged between 20 and 49, as it is the only behavioural risk factor that follows the same trend. However, it does not fully explain the increase, with improved detection methods possibly explaining why more people are receiving diagnoses at a younger age.
New research has shown that pre-diabetic individuals who harbour certain mutations in a vitamin D receptor gene can cut their risk of developing diabetes by taking daily vitamin D supplements. The research highlights the important role of genomics in personalised medicine strategies.
Scientists have developed a method to track individual molecules inside living cells, shedding light on how proteins linked to cancer operate. The technique reveals how these proteins move and interact over time, offering a clearer picture of the molecular processes that control gene activity and contribute to tumour development.
Researchers have developed a non-invasive imaging approach to track how the immune system responds to cancer therapy across the whole body. Using a mouse model, the study showed that a virus-based treatment triggered a temporary, system-wide immune response detectable in key immune organs rather than just the treated tumour.
Researchers have created an artificial intelligence system designed to assist pathologists in evaluating challenging lung cancer samples. By detecting subtle features in tissue images, the tool can enhance diagnostic precision and support more tailored treatment planning
A study has uncovered previously unrecognised factors involved in pancreatic cancer, a disease known for its poor prognosis. These findings point to new biological pathways that may drive cancer evolution, such as a mechanism that allows the tumour cells to ‘hide’ from the immune system, opening up possibilities for improved detection and the development of targeted therapies.
A multi-ancestry analysis of data from more than one million women has advanced understanding of the biological basis of endometriosis. The study identified genetic and molecular contributors to the condition, offering new avenues for research into better diagnosis and treatment.
Researchers have identified a gene that is essential for maintaining the stability and function of intestinal stem cells. Loss of this gene causes the cells to revert to a more primitive state and prevents them from maturing into specialised cell types, highlighting its importance in tissue maintenance and regeneration.
