Freeze-dried mice: How a new technique could help conservation NatureComms
'Very exciting advance'of cloning mice from cells stored in liquid nitrogen or at ultra-low temperatures is between two and five percent, while the freeze-dried method is just 0.02 percent.
"We believe the most important thing is that cloned mice have been produced from freeze-dried somatic cells, and that we have achieved a breakthrough in this field," he said. "It can be difficult and costly to work up cryopreservation protocols and so alternatives, especially those that are cheaper and robust, are extremely welcome," added Clulow, who was not involved in the research.
The technique could eventually"allow genetic resources from around the world to be stored cheaply and safely", Wakayama said.

Physicists Stunned by Nature in the Wrong Direction: Magnetic Spins That “Freeze” When HeatedPhysicists observed a very strange new type of behavior in a magnetic material when it’s heated up. When the temperature rises, the magnetic spins ‘freeze’ into a static pattern, a phenomenon that normally occurs when the temperature decreases. Their findings were published in Nature Physics today,

Nanoparticle single-cell multiomic readouts reveal that cell heterogeneity influences lipid nanoparticle-mediated messenger RNA delivery - Nature NanotechnologyCell heterogeneity might impact the delivery of lipid nanoparticles (LNPs) and efficacy of messenger RNA-based therapies in vivo. Here, the authors propose an approach to measure how various LNPs deliver DNA barcodes and mRNA to cells using single-cell RNA sequencing, providing a correlation between LNP uptake and the expression of specific genes that characterize cellular subtypes.
