It takes more than one mutant copy of the PIK3CA gene to make breast cancer more aggressive, study finds

Breast cancers that have an overactive PI3K enzyme tend to be more aggressive and to spread and divide more like stem cells. But a new study uncovers a surprising relationship between PI3K activity and mutations in the PIK3CA gene that codes for the enzyme.

Function of mysterious structure found on neurons

Researchers have discovered that mysterious clusters of proteins found on neurons are calcium-signaling 'hotspots' that activate gene transcription, allowing neurons to produce crucial proteins. The discovery may help shape new research into the role of the hotspots in brain function and potentially lead to new classes of therapeutics.

Plant-based gummy candy helps vegans and vegetarians get their vitamins

Worldwide, millions of people follow vegan and vegetarian diets for religious, ethical, environmental or economic reasons. While these diets have purported health benefits, they can also lack essential nutrients, such as vitamins B12 and D3, if not well-planned or supplemented correctly. Now, researchers have packed a strawberry-flavored gummy with these vitamins, formulating it without any animal products so vegans and vegetarians can reach their recommended daily allowances (RDA).

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.
