Fat-secreted molecule lowers response to common cancer treatment

Leptin, a molecule produced by fat cells, appears to cancel out the effects of the estrogen-blocking therapy tamoxifen, a drug commonly used to treat and prevent breast cancers, suggests a new study.

For women, greater exposure to estrogen in life may protect brain regions that are vulnerable to Alzheimer’s

The drop in estrogen levels that occurs with menopause brings declines in the volumes of 'gray matter,' the cellular matter of the brain, in key brain regions that are also affected in Alzheimer's disease. But a new study suggests that greater cumulative exposure to estrogen in life, for example from having had more children or from having taken menopause hormone therapy, may counter this brain-shrinking effect.

Nanoscale self-assembling salt-crystal ‘origami’ balls envelop liquids

Mechanical engineers have devised a technique of 'crystal capillary origami' where salt crystals spontaneously encapsulate liquid droplets. The process offers a new method of nanostructure encapsulation for applications in food industries, drug delivery and even medical devices.

Researchers identify molecule that blocks immune cells from entering and killing breast tumors

Researchers have identified a key molecule in certain kinds of breast cancers that prevent immune cells from entering tumors and killing the cancer cells inside. This research could pave the way toward a new treatment for certain kinds of aggressive breast cancer.

Chemo helps breast cancer cells get their ‘foot in the door’ to the lungs

A new study adds to the evidence that chemotherapy enhances cancer's spread beyond the primary tumor, showing how one chemo drug allows breast cancer cells to squeeze through and attach to blood vessel linings in the lungs.

Sperm switch swimming patterns to locate egg

A new study reveals how sperm change their swimming patterns to navigate to the egg, shifting from a symmetrical motion that moves the sperm in a straight path to an asymmetrical one that promotes more circular swimming.
