Nurses cut stress 40 percent with relaxation steps at work
It's estimated that one million people a day miss work in the United States because they're too stressed out. To help lower stress in the workplace, researchers at The Ohio State University Wexner Medical Center conducted a study with staff members in a surgical intensive care unit. They found that a few simple on-the-job relaxation techniques cut stress levels by 40 percent and lowered the risk of burnout. (2015-05-11)

miR loss may power maligant transformation in chronic leukemia
This study shows that loss of a particular molecule in chronic lymphocytic leukemia (CLL) shuts down normal cell metabolism and turns up alternative mechanisms that enable cancer cells to produce the energy needed to proliferate and invade neighboring tissue. The study shows that the molecule, miR-125b, is often lost in CLL, and that the loss is associated with a characteristic of cancer cells called the Warburg effect. (2012-07-05)

Ancient human ear-orienting system could yield clues to hearing deficits in infants
Vestigial organs, such as the wisdom teeth in humans, are those that have become functionless through the course of evolution. Now, a psychologist at the University of Missouri studying vestigial muscles behind the ears in humans has determined that ancient neural circuits responsible for moving the ears, still may be responsive to sounds that attract our attention. Neuroscientists studying auditory function could use these ancient muscles to study positive emotions and infant hearing deficits. (2015-10-12)

Ancient coral reef record gives history of El Niño
Using pieces of ancient coral reefs as windows on the history of climate, geologists have discovered that at no time in the past 130,000 years does the weather phenomenon known as El Niño appear to have been as intense as it has in the last century. (2001-01-24)

Who do you trust? Men and women answer that differently
Men and women differ in how they decide which strangers they can trust, according to new research. A study found that men tended to trust people who were part of a group with them. Women, on the other hand, were more likely to trust strangers who shared some personal connection, such as a friend of a friend. (2005-07-05)

2 genes found to play crucial role in cell survival
New research suggests that two recently discovered genes are critically important for controlling cell survival during embryonic development. The genes, called E2F7 and E2F8, are members of a family of genes that play a fundamental role in development. Members of this family are also involved in cancers of the breast, bladder, stomach and colon. This animal study showed that complete loss of the two genes causes massive cell death and is lethal in developing embryos. (2008-02-04)

Integration: A centuries-old issue
When can a person be regarded as a full and equal citizen of a country? Is a double nationality possible and what advantages does it offer a newcomer?

Organic carbon from Mars, but not biological
Molecules containing large chains of carbon and hydrogen -- the building blocks of all life on Earth -- have been the targets of missions to Mars from Viking to the present day. While these molecules have previously been found in meteorites from Mars, scientists have disagreed about how this organic carbon was formed and whether or not it came from Mars. A new paper provides strong evidence that this carbon did originate on Mars, although it is not biological. (2012-05-24)
