Intestines modify their cellular structure in response to diet

Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie's Rebecca Obniski, ...

Scavengers "protect" HDL

High-density lipoprotein (HDL) is widely thought to protect against the development of atherosclerosis, yet drugs that raise levels of HDL cholesterol (HDL-C) have failed to reduce the risk of heart disease.

Scientists break down tuberculosis structure

Scientists from the University of British Columbia have taken a crucial step towards starving out tuberculosis, following research into how the infection grows in the body.

How scientists analyze cell membranes

Exchange of material and information at the level of individual cells requires transport and signaling at the level of the plasma membrane enclosing the cell. Studying mechanisms at such tiny dimensions presents researchers ...

Key tethering protein found to transport cellular cholesterol

Despite its less-than-stellar reputation in the news, cholesterol is an essential molecule for living things. It serves as the building block for hormones and gives shape to the membranes that enclose cells and their internal ...

Graphene material strengthens nerve signaling in the brain

Less than 20 years after it was developed, a thin, resilient sheet of carbon atoms with remarkable properties known as graphene is transforming biomedical fields as far flung as tissue engineering, neuroprosthetics and drug ...
