It's uncommon for there to be reanalyses of data from randomized clinical trials (RCTs) - once a product has failed, it isn't smart to keep putting more money into it.


Like most young people, the first job is not the best job and they will often leave when a better opportunity comes along. 

There is strong demand for nurses so it's no surprise that there is turnover among young ones. Once they prove they can do the job, hospitals and practices are going to recruit them and pay higher salaries, because they are not paying training costs.

A study in the current issue of Policy, Politics&Nursing Practice reveals that an estimated 17.5 percent of newly-licensed RNs leave their first nursing job within the first year and one in three (33.5%) leave within two years. The scholars found that turnover for this group is lower at hospitals than at other health care settings.


Before they reach young adulthood, many children in the United States will experience their parents separating, divorcing, finding another partner or getting remarried. 


When families change structure, it is more common for children to exhibit behavior problems, such as aggression and defiance, and a new psychology paper say that behavior problems in children increased in high-income families most, and that children's age also played a part in their likelihood of having behavior problems.

Moving from a single-parent family into a step-parent family then improved children's behavior in higher-income families but not in lower-income families.

A panic erupted in Britain 126 years ago.

At daybreak on Saturday September 8, the mutilated body of Annie Chapman, a prostitute, had been found in the back yard of 29 Hanbury Street, Spitalfields.

Her injuries and the removal of some of her abdominal organs led investigators and journalists to link Chapman’s murder with that of another woman, only a week earlier.

If depictions of animals in ancient Egyptian artifacts are an accurate climate record, they have helped scholars assemble a detailed record of the large mammals that lived in the Nile Valley over the past 6,000 years.

They then determined that species extinctions, probably caused by a drying climate and growing human population, made the ecosystem progressively less stable.

The life sciences have come under fire recently with a study published in PLOS ONE that investigated the level of sexual harassment and sexual assault of trainees in academic fieldwork environments.

It wasn’t that long ago that it was believed that regular periods were essential for women's health and in their absence, a loss of blood through another orifice was a fair substitute.

In a classical Greek text linked to Hippocrates, the Aphorisms, it was written that “a nosebleed is a good thing if the menstrual period is suppressed”. So too was vomiting blood. And these beliefs lasted in western Europe until the middle of the 19th century.

But what was the theory behind what now seems a pretty alarming set of beliefs?
