Deep brain stimulation (DBS), an experimental technology that involves implanting a pacemaker-like device in a patient’s brain to send electrical impulses, is a hotly debated subject in the field of medicine. It is an inherently risky procedure and the exact effects on the human brain aren’t yet fully understood.
But some practitioners believe it could be a way to alleviate the symptoms of depression or even help treat Alzheimer’s — and now they suspect it could help with drug addiction as well. In a world’s first, according to the Associated Press, a patient in Shanghai’s Ruijin Hospital had a DBS device implanted in his brain to treat his addiction to methamphetamine. And the device has had an astonishingly positive effect, the patient says. “This machine is pretty magical. He adjusts it to make you happy and you’re happy, to make you nervous and you’re nervous,” he told the Associated Press. “It controls your happiness, anger, grief and joy.”
Other studies in China have yielded mixed results trying to treat opioid addictions using DBS, according to the AP. In the United States, at least two studies that tried to treat alcoholism with DBS were dropped for not being able to justify the risks. The idea of using DBS to treat drug addiction has raised concerns in medical communities across the globe about brain hemorrhage, seizures, or personality changes.

     Improving girls’ educational levels has been demonstrated to have clear impacts on the health and economic future of young women, which in turn improves the prospects of their entire community. The infant mortality rate of babies whose mothers have received primary education is half that of children whose mothers are illiterate. In the poorest countries of the world, 50% of girls do not attend secondary school. Yet, research shows that every extra year of school for girls increases their lifetime income by 15%. Improving female education, and thus the earning potential of women, improves the standard of living for their own children, as women invest more of their income in their families than men do. Yet, many barriers to education for girls remain. In some African countries, such as Burkina Faso, girls are unlikely to attend school for such basic reasons as a lack of private latrine facilities for girls.

       Higher attendance rates of high schools and university education among women, particularly in developing countries, have helped them make inroads to professional careers with better-paying salaries and wages. Education increases a woman’s (and her partner and the family’s) level of health and health awareness. Furthering women’s levels of education and advanced training also tends to lead to later ages of initiation of sexual activity and first intercourse, later age at first marriage, and later age at first childbirth, as well as an increased likelihood to remain single, have no children, or have no formal marriage and alternatively, have increasing levels of long-term partnerships. It can lead to higher rates of barrier and chemical contraceptive use (and a lower level of sexually transmitted infections among women and their partners and children), and can increase the level of resources available to women who divorce or are in a situation of domestic violence. It has been shown, in addition, to increase women’s communication with their partners and their employers, and to improve rates of civic participation such as voting or the holding of office.
