New hair follicles can corral skin cancer

The same genetic mutations that can trigger cancer in some tissues are relatively harmless in others. A new Yale study has identified an unlikely source of protection against some forms of skin cancer—hair follicle regeneration.

A new signaling pathway for mTor-dependent cell growth

The activation of mTor complex 1 in the cell is central to many vital processes in the body such as cell growth and metabolism. Overactivity of this signaling pathway can result in diseases such as in diabetic insulin resistance ...

A 'switch' that regulates traffic across blood vessels

NUS scientists have discovered a control mechanism that regulates the traffic of cells and substances across blood vessels. This effect can have significant impact on cancer metastasis.

Molecular bait can help hydrogels heal wounds

Like fishermen, Rice University bioengineers are angling for their daily catch. But their bait, biomolecules in a hydrogel scaffold, lures microscopic stem cells instead of fish.

Nanoscopic protein motion on a live cell membrane

Cellular functions are dictated by the intricate motion of proteins in membranes that span across a scale of nanometers to micrometers, within a time-frame of microseconds to minutes. However, this rich parameter of space ...
