Damage to cell membranes causes cell aging, finds new study

Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury. To cope with such ...

Genome database for desiccation-tolerant plants released

Desiccation is typically fatal for plant vegetative tissues, but a small number of land plants have evolved vegetative desiccation tolerance (VDT), allowing them to dry without dying through a process called anhydrobiosis.

A new model for the evolution of honey bee brains

Researchers have proposed a new model for the evolution of higher brain functions and behaviors in the Hymenoptera order of insects. The team compared the Kenyon cells, a type of neuronal cell, in the mushroom bodies (a part ...

Team investigates sex-determination mechanisms in birds

Scientists have known that sex-determination in vertebrates happens in the germ cells, a body's reproductive cells, and the somatic cells, the cells that are not reproductive cells. Yet they have not fully understood the ...
