Scientists Discover Molecular 'Passports' That Control Cell Nuclei
Israeli and US scientists have discovered how tiny gateways in human cells control what enters and leaves the cell's nucleus, solving a mystery that has puzzled researchers.

Mitochondria Divide Roles for Energy and Molecular Synthesis Under Low-Nutrient Conditions, Reveals New Study
New findings reveal that mitochondria in nutrient-deprived cells adopt specialised roles to prioritise either energy generation or amino acid synthesis. Led by Dr. Craig Thompson of Memorial Sloan Kettering Cancer Center, the study identified specific mitochondrial subpopulations, allowing cells to maintain critical functions even under stress. The...

Scientists Double Life Expectancy For Embryos In Petri Dishes, Raising Ethical Concerns
When scientists grow human embryos for lab research, they end their experiments at the 14-day mark. Until now, these internationally accepted guidelines (and the laws formed around them) have been largely self-regulating: The record for in-vitro gestation was just nine days, and most labs struggled to keep embryos alive longer then a week.
