"Cryopreservation doesn’t just preserve genetic lineages – it transforms extinction from a permanent loss into a temporary inconvenience we can choose to address later."

Cryolab has published a clinical comparison of vitrification vs slow freezing for IVF laboratories.
Oocyte survival 90%+ with vitrification vs 50–80% with slow freezing. Blastocyst survival 95%+ vs 70–85%. ESHRE 2020 guidelines recommend vitrification for oocytes and embryos. Slow freezing remains standard for sperm banking.

Oh wow! Potentially crucial technical breakthrough for #cryopreservation! Individuals were frozen, placed in liquid nitrogen and then successfully revived 12 months later!
Obviously, that was done in #drosophila - what did you think? 😆

Nuestra ultima entrevista!
La UVigo ha establecido el primer protocolo para criopreservar un gusano marino que forma parte de la fauna de las rías gallegas y cuya utilización como modelo para estudios de neurociencia, desarrollo y biología evolutiva va en aumento en todo el mundo. El logro es fruto de la colaboración entre investigadoras del Centro de Investigación Mariña (CIM) y expertos del Max Perutz Labs (Universidad de Viena) que cuentan con un biobanco de la especie Platynereis dumerilii para sus trabajos.

Project to ‘freeze’ decline of iconic #butterfly
New collaboration investigates if cryopreservation can help the British #Swallowtail

#science #conservation #cryopreservation #insects #lepidoptera
A groundbreaking project has been launched to help protect one of the UK’s most spectacular insects – the British Swallowtail butterfly. The British Swallowtail’s population has significantly declined over the last 20 years and researchers from Anglia Ruskin University (ARU) in England are working with Jimmy’s Farm & Wildlife Park and Nature’s SAFE, a UK biobank specialising in conservation, to investigate if cryopreservation can support the long-term conservation of the species. It is believed this is the first time that cryopreservation, where the eggs will be stored in liquid nitrogen at -196 Celsius, has been attempted with butterflies.
