Cells use import machinery to export their goods as well

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory.

New understanding of roles of insulin in obesity or type II diabetes

Researchers have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin.

Normal-looking sperm may have serious damage; scientists urge more care in selection

Intracytoplasmic sperm injection (ICSI), where a single sperm is injected into an egg to fertilise it, is increasingly used to help infertile men father children. Although the sperm chosen for the procedure may appear quite normal, researchers in the US have found that many of them in fact have DNA damage, which can decrease the chances of pregnancy.

Viruses hitch a ride in the cell

Viruses can travel around cells they infect by hitching a ride on a microscopic transport system, according to new research. Cells are exposed to foreign DNA and RNA and it is understood that some of this genetic material can be integrated into the host genome. Using modern microscopic techniques, scientists have been able to see how virus DNA is transported in the cell.
