Before #cells can divide, they first need to replicate all of their #chromosomes, so that each of the daughter cells can receive a full set of #genetic material. Until now, scientists had believed that as division occurs, the #genome loses the distinctive 3D internal structure that it typically forms.

#Lipids are fatty #molecules that play critical roles in cell function, including membrane structure, energy storage and nutrient absorption. Most lipids are made in a cell #organelle called the #endoplasmic reticulum, but specific lipid types are shuttled around to different parts of the cell depending on their purpose.

#Water is everywhere – it covers most of the earth, circulates in the human body and can be found in even the smallest #molecular niches. But what happens if water does not flow freely but is trapped in such structures?

This study contradicts the more traditional #evolutionary view — on island-colonizing species, whose #genomes are larger and often have more repetitive elements — and expands the scientific debate on a major puzzle in evolutionary biology: how and why does genome size change during the evolution of living beings?

In a mouse model of #liver #transplantation, UCLA researchers have identified #proteins that act as “protective switches” guarding the liver against damage occurring when blood supply is restored during transplantation, a process known as ischemia-reperfusion injury.
