How early cell membranes may have shaped the origins of life
A new study suggests that physical properties guided life before genes did. Phospholipids with more unsaturated bonds were more likely to merge and grow under freeze-thaw cycles.

Enhanced Raman microscopy of cryofixed specimens: clearer and sharper chemical imaging
Osaka University researchers have reported a method that gives high-resolution Raman microscopy images of biological samples, up to eight times brighter than previous methods. This technique uses no stains and doesn't require chemicals to fix cells in position, providing a highly representative view of processes and cell behavior.
Generation of rat offspring from ovarian oocytes by Cross-species transplantation
Researchers at Niigata University successfully generated rat offspring from ovarian oocytes transplanted into mice, overcame previous challenges in producing fertilized eggs and embryos.
New technology for long-term liquid storage of chicken semen by arresting energy metabolism
Chicken sperm can retain fertility and viability for up to three weeks after refrigeration, making it unsuitable for traditional cryopreservation methods. The study found that removing calcium ions impacts energy metabolism dynamics, inducing a physiological dormancy-like state in the sperm cells.
Nanosatellite shows the way to RNA medicine of the future
Scientists at Aarhus University and Berkeley Laboratory developed a method called RNA origami to design artificial RNA nanostructures. The technique allowed for the discovery of rules and mechanisms for RNA folding that will make it possible to build more ideal RNA particles for use in RNA-based medicine.
Scientists identify ‘bottleneck’ in drug delivery pathways in stem cells
Researchers developed a mathematical model to predict the efficiency of nanoparticle delivery into cells, particularly in stem cells. They found that nanoparticles become trapped in bubble-like vesicles, preventing them from reaching their targets.
Antifreeze cream prevents frostbite injuries to skin
Researchers have developed a cream that prevents frostbite injuries in mice when applied to the skin before severe cold exposure. The cream, called SynAFP, reduces frostbite wound size and speeds healing compared to no treatment. Further studies are needed to determine its effects on humans.
