Immune system compromised during spaceflight, study finds

Astronauts are known to have a higher risk of getting sick compared to their Earth-bound peers. The stresses that go with weightlessness, confined crew quarters, being away from family and friends and a busy work schedule ...

Production of iPS cells: Discovery of the fifth element

Since 2006, research has succeeded in generating, from specialised adult cells, induced pluripotent cells (iPS cells), with huge potential applications, particularly for regenerative medicine. However, the process has still ...

How mitochondria get their membranes bent

Underneath their smooth surface mitochondria harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities. Now researchers have identified two proteins ...

MicroRNA undermines tumor suppression

A small piece of RNA, or microRNA (miRNA), ratchets down the activity of the tumor-suppressor gene p53, according to a study by Whitehead Institute and National University of Singapore researchers.
