Full-time professional to full-time mother: A choice laden with cost

Women leaving work to raise children have to redefine who they are, a study from the SAGE journal Human Relations finds. After exiting professional and managerial occupations, mothers are engaged in an ongoing mother/professional identity struggle, argue the researchers Shireen Kanji and Emma Cahusac. The process through which the mothers’ choice is constructed as ‘right’ does not occur before their exit from work but manifests itself afterwards and intensifies over time, the study reveals.

New guidelines for cancer doctors aim to make sense of gene tests

Freitas, a 3-year-old cancer patient, is carried by his parents before an injection in a hospital in BarretosBy Julie Steenhuysen CHICAGO (Reuters) – The American Society of Clinical Oncology (ASCO) has issued guidelines on how cancer doctors should approach the use of new genetic tests that screen for multiple cancer genes at the same time, including counseling patients about genes whose contribution to cancer is still poorly understood. The guidelines aim to educate doctors about the risks and benefits of new genetic tests, argue for regulation to assure quality and call for more equitable reimbursement of the cost of the tests from private and public insurers. The falling price of genome sequencing has made it possible for cancer doctors to cheaply test for a wide variety of mutated genes that could guide treatment or predict a person's risk for cancer.

Elusive Sea Creature with Hairy, Slimy Shell Spotted After 31 Years

Elusive Sea Creature with Hairy, Slimy Shell Spotted After 31 YearsThe Allonautilus scrobiculatus, a species of mollusk in the same family as the nautilus, was spotted off the coast of Papua New Guinea in the South Pacific in early August, the scientists said. The Allonautilus' shell has been known to science since the 1700s. The Allonautilus is so rare likely because it is completely reliant on scavenging to survive, Ward said.

Human Eye’s Blind Spot Can Shrink with Training

The blind spot of the human eye can be shrunk with certain eye-training exercises, thus improving a person’s vision slightly, a small new study suggests. In the study of 10 people, researchers found that the blind spot — the tiny region of a person’s visual field that matches up with the area in the eye that has no receptors for light, and hence cannot detect any image — can shrink 10 percent, with special training. That amount of change “is quite an improvement, but people wouldn’t notice, as we are typically unaware of our blind spots,” said study author Paul Miller, of the University of Queensland in Australia.

Sexual Harassment in the Animal Kingdom? How Female Guppies Escape

Sexual Harassment in the Animal Kingdom? How Female Guppies EscapeAnimal-behavior scientists discovered that female fish who were most bothered by this type of sexual harassment started to swim in a different, more efficient way. Researchers from the University of Glasgow and the University of Exeter, both in the United Kingdom, tested the effects of this harassment on Poecilia reticulata guppies. "In the wild, especially during the dry season, [guppies] can be trapped together in small pools for months," said study lead author Shaun Killen, a biologist at the University of Glasgow.
