Ambulatory health care took off in the 1980s as the cost of health care rose, more people got health insurance, and both the government and health insurers sought to contain the runaway costs associated with hospital visits by keeping people out of hospitals.

Researchers have identified an enzyme,  PRSS3, specifically linked to aggressive prostate cancer, and have also developed a compound that inhibits the ability of this molecule to promote the metastatic spread of the cancer.

They made the discovery by investigating publicly available databases, derived from clinical studies, which contain data on molecules that are upregulated - irregularly switched on - in cancer. They had previously discovered a link between the protease and the earlier stages of breast cancer. The research team wanted to see if any other cancer abnormally expresses this protease, and at what stages so they mined multiple databases. 

There are some kinds of turbulence we know exists but proving it is difficult - turbulence in the ionized gas that fills the universe is one such example.

But now a research team says they have directly measured it for the first time - in the laboratory.

The current raging ethical debate in western health care is not how to save lives but how to end them. The controversial Liverpool Care Pathway in the UK, for example, where health care is nationalized, is really a death pathway. Unfortunately, half of the people on it are never told they are on it.

Canada has a different ethical problem; a whole bunch of citizens want to be smarter. It's been found that stimulants and neuropharmaceuticals prescribed to treat attention deficit disorder (ADD) really boost the concentration, memory, alertness and mood of people without ADD.

A desire for expensive, high-status stuff is related to feelings of social status, not social status itself, and that helps why minorities are attracted to 'bling', say psychologists.

Previous psychology work has shown that racial minorities spend a larger portion of their incomes than do whites on conspicuous consumption and buying products that suggest high status, like cars with rims made of platinum or gold teeth inserts. But bling is not actually biological, so whites also crave expensive, high-status products - if they imagine themselves in a low-status position. Thus, corrosive "bling culture" that is not unique to urban minorities, says Philip Mazzocco, lead author of a new paper and assistant professor of psychology at Ohio State University's Mansfield campus.

Researchers say they have discovered a new form of cell division in human cells, which they believe serves as a natural back-up mechanism during faulty cell division, preventing some cells from going down a path that can lead to cancer. 

"If we could promote this new form of cell division, which we call klerokinesis, we may be able to prevent some cancers from developing," says lead researcher Dr. Mark Burkard, an assistant professor of hematology-oncologyat the UW School of Medicine and Public Health, who studies cancers in which cells contain too many chromosomes, a condition called polyploidy, and also sees breast cancer patients.
