Do you want a better sex life and a better relationship to go with it? Sociologists say surveys show that if men take up more of the child-care duties, splitting them equally with their female partners, heterosexual couples have more satisfaction with their relationships and their sex lives, according to new research by Georgia State University sociologists.

Daniel L. Carlson, along with graduate students Sarah Hanson and Andrea Fitzroy, all of Georgia State University, used data from more than 900 heterosexual couples' responses in the 2006 Marital Relationship Study (MARS). 

They found that when women were responsible for most or all of the child care, both parties reported both the lowest quality relationships and sex lives.

Does watching the news make you lose faith in a higher purpose? Does taking out an army of terrorists alone without so much as a scratch make you feel like you must have a divine gift? An analysis of cellphone data shows that spiritual awareness does vary based on activity, rather than being constant, according to sociologists at the American Sociological Association meeting who say that people had the highest levels of spiritual awareness in the morning and while engaged in activities such as praying, worship, and meditation. Spiritual awareness also was high when people listened to music, read, or exercised. It was low while people were doing work-related activities or playing video games. 

Regular consumption of caffeinated coffee may help prevent the return of colon cancer after treatment and improve the chances of a cure, according to a new study.

The patients, all of them treated with surgery and chemotherapy for stage III colon cancer, had the greatest benefit from consuming four or more cups of coffee a day (about 460 milligrams of caffeine), according to the study. These patients were 42 percent less likely to have their cancer return than non-coffee drinkers, and were 33 percent less likely to die from cancer or any other cause.

As more money has been spent on biomedical research in the United States over the past 50 years, there has been diminished return on investment in terms of life expectancy gains and new drug approvals, two Johns Hopkins Bloomberg School of Public Health researchers say.

In a report published Aug. 17 in the Proceedings of the National Academy of Sciences, the researchers found that while the number of scientists has increased more than nine-fold since 1965 and the National Institutes of Health's budget has increased four-fold, the number of new drugs approved by the Food and Drug Administration has only increased a little more than two-fold. Meanwhile, life expectancy gains have remained constant at roughly two months per year.

Scientists working have developed a brain-computer control interface for a lower limb exoskeleton by decoding specific signals from within the user's brain using an electroencephalogram (EEG) cap.

The system allows users to move forwards, turn left and right, sit and stand simply by staring at one of five flickering light emitting diodes (LEDs), according to the paper in the Journal of Neural Engineering.

Each of the five LEDs flickers at a different frequency, and when the user focusses their attention on a specific LED this frequency is reflected within the EEG readout. This signal is identified and used to control the exoskeleton.

Same-sex couples encounter more obstacles to fertility treatment than traditional couples,  said Ann V. Bell, an assistant professor of sociology at the University of Delaware, who noted that the U.S. medical system is standardized to work with heterosexual couples.
