We all get by with a little help from our friends, but that help is much more valuable when it’s given in person rather than via email or telephone. A new study from Oregon Health & Science University shows that face-to-face interactions are more powerful than digital ones at warding off depression in older adults.
The study, which was published online Monday in the Journal of the American Geriatrics Society, showed that older adults who met regularly with family and friends were 5 percent less likely to report symptoms of depression, compared to those who spoke with their loved ones via email or phone. The benefits lasted for at least two years.
“We don’t know precisely what the magic ingredient is, but our results imply there is something special and uniquely effective about meeting up in-person in terms of preventing future depression,” Dr. Alan Teo, an assistant professor of psychiatry at the university, told The Huffington Post in an email.
For the study, the researchers analyzed data from over 11,000 adults over the age of 50 who participated in a longitudinal study with the University of Michigan, measuring each individual’s frequency of in-person, telephone and written (including email) social interactions. Two years after collecting that data, the researchers assessed the study participants’ risk for depression, taking into consideration factors including pre-existing depression, physical health and proximity to family.
What did the researchers find? Individuals who had little face-to-face contact with friends and family had a nearly doubled risk of depression two years later. Frequent phone calls, emails and other types of communication had no effect on a person’s risk for depression.
Among older adults who spent time with their families at least three times a week, only 6.5 percent were at risk for depression. Those who saw their loved —> Read More

X-ray crystallography reveals the three-dimensional structure of a molecule, especially for therapeutic or biotechnological purposes. For the first time, a study has shown that residual movements continue to animate proteins inside a crystal and that this movement ‘blurs’ the structures obtained via crystallography. The study stresses that the more these residual movements are restricted, the better the crystalline order. —> Read More
A single-electron transistor is an electrical device that takes advantage of a strange quantum phenomenon called tunneling to transport single electrons across a thin insulator. The device serves as an on/off switch on the tiniest scale and could play an important role in quantum computing. —> Read More
Researchers have developed an automated ‘debugging’ approach called Adaptive Multimodal Bug Localisation (AML). AML gleans debugging hints from both bug reports and test cases, and it performs a statistical analysis to pinpoint program elements that are likely to contain bugs. —> Read More
