Social life in youth may impact health decades later
Robert Preidt
August 6, 2015
Having good social connections at age 20 can lead to improved well-being later in life, a new study suggests. Previous research has shown that people with poor social links are at increased risk for early death. “In fact, having few social connections is equivalent to tobacco use, and [the risk is] higher than for those who drink excessive amounts of alcohol, or who suffer from obesity,” study author Cheryl Carmichael, who conducted the study while a doctoral candidate at the University of Rochester in New York, said in a university news release.
The study included 133 people who enrolled when they were 20-year-old college students in the 1970s. The participants kept track of their daily social interactions at ages 20 and 30. At age 50, they completed an online survey about the quality of their social lives and emotional well-being, including questions about loneliness and depression, and their relationships with close friends.
The findings showed that frequent social interactions at age 20 and good-quality relationships – defined as intimate and satisfying – at age 30 were associated with higher levels of well-being at age 50. The study findings were published in a recent issue of the journal Psychology and Aging.
A high number of social interactions at age 20 are beneficial later in life because they help young adults determine who they are, the researchers said. “It’s often around this age that we meet people from diverse backgrounds, with opinions and values that are different from our own, and we learn how to best manage those differences,” said Carmichael, now an assistant professor of psychology at Brooklyn College. “Considering everything else that goes on in life over those 30 years – marriage, raising a family and building a career – it is extraordinary that there appears to be a relationship between the kinds of interactions college students and young adults have and their emotional health later in life,” she concluded.

Artificial intelligence and the future of medicine
Right now, the challenges we need to address as we try to bring AI into medical practice include improving the quality of the data that we feed into AI systems, developing ways to evaluate whether an AI system is actually better than standard of care, ensuring patient privacy and making sure not only that AI doesn't disrupt clinical work flow but in fact improves it. But if doctors do their jobs right and build these systems well, much of what we have described will become so ingrained in the system, people won't even refer to it separately as informatics or AI. It will just be medicine.

Dying to defend the planet: why Latin America
is the deadliest place for environmentalists
February 11, 2017
Defending nature is a dangerous occupation, especially in Latin America. According to a recent report by Global Witness, an NGO, 185 environmental activists were murdered worldwide in 2015, an increase of 59% from the year before. More than half the killings were in Latin America. In Brazil 50 green campaigners died in 2015. Honduras is especially dangerous: 123 activists have died there since 2010, the highest number of any country relative to its population. Berta Cáceres, an indigenous leader who was a prominent campaigner against dams and plantations, was murdered there.
Why is Latin America so deadly? One reason is its abundant natural resources, which attract enterprises of all sorts, from multinationals to mafias. When prices are low, as they are now, the most rapacious do not go away; to maintain their profits they become more aggressive, says David Kaimowitz of the Ford Foundation, which gives money to good causes. New technologies open up new battlefronts. Soya beans bred to grow in tropical conditions have encouraged farmers to displace cattle ranchers, who in turn have advanced into the rainforest. Small prospectors can now extract gold from soil rather than just hunting around. That opens up new areas for exploitation, such as San Rafael de Flores in south-eastern Guatemala, where activists have been murdered.
The odds of finding the criminals are greater if the victim is foreign. Dorothy Stang, an American nun who fought to protect the Amazon rainforest, was killed in Brazil 12 years ago. Both the gunman and a rancher who had hired him eventually went to jail. But that is an exception.
