Researchers found that compared with the group taking the placebo, those taking vitamin D supplements had reduced telomere shortening over four years. Omega-3 fatty acid supplementation, on the other hand, had no obvious effect on telomere length.

Menace sur le #chromosome Y : ce nouveau gène pourrait façonner l’avenir des hommes http://sci3nc.es/TL5YC0

There will be a 80-minute open-call symposium (a parallel session) on

"Genome Alignments: Are We Ready to Unravel Evolution Across the Tree of Life?"

at the #MBSJ2025 (#Molecular #Biology Society of #Japan) #conference, also known as "#Bunsei", in #Yokohama on December 3rd; I am co-organiser with Martin Frith. We have a couple of slots left for 10~15 min talks with a the possibility of partial support for international speakers. We are on a mission that no gender should be over-represented, and you surely can guess which one is at the moment.

Here is the symposium abstract: #Chromosome-scale and complete #genome #assemblies are becoming available for organisms across the whole #TreeofLife. Genome #alignments empower studies that cover #evolutionary scales from thousands to billions of years. This symposium will present the latest biological insights obtained from genome alignments as well as new methods, software and pipelines.

Please contact me at my work email if you have some results that fit well and you would like to present! Here is the URL to the conference website.
