A Mechanical Neural Network – A New Type Of Material That Can Learn And Change Its Physical Properties To Create Adaptable, Strong Structures

A new type of material can learn and improve its ability to deal with unexpected forces thanks to a unique lattice structure with connections of variable stiffness, as described in a new paper by my colleagues and me. Architected materials – like this 3D lattice – get their properties not from what they are made out of, but from their structure. Ryan Lee, CC BY-ND The new material is a type of architected material, which gets its properties mainly from the geometry and specific traits of its design rather than what it is made out of. Take hook-and-loop fabric closures like Velcro, for example. It doesn’t matter whether it is made from cotton, plastic or any other substance. As long as one side is a fabric with stiff hooks and the other side has fluffy loops, the material will have the stic...

Middle-Aged Americans In The US Are Stressed And Struggle With Physical And Mental Health – Other Nations Do Better

Frank J. Infurna, Arizona State University Midlife was once considered a time to enjoy the fruits of one’s years of work and parenting. That is no longer true in the U.S. Deaths of despair and chronic pain among middle-aged adults have been increasing for the past decade. Today’s middle-aged adults – ages 40 to 65 – report more daily stress and poorer physical health and psychological well-being, compared to middle-aged adults during the 1990s. These trends are most pronounced for people who attained fewer years of education. Although these trends preclude the COVID-19 pandemic, COVID-19’s imprint promises to further exacerbate the suffering. Historical declines in the health and well-being of U.S. middle-aged adults raises two important questions: To what extent is this confined to the...

State Laws Are Beginning To Recognize That Domestic Violence Isn’t About Just Physical Violence

Three or more U.S. women are murdered every day by their current or former intimate partner. That may in part be due to a failure of state laws to capture the full range of behavior that constitutes domestic abuse. The law continues to treat intimate partner violence like a bar fight – considering only what happened in a given incident and not all the prior abuse history, such as intimidation and entrapment. Research shows, however, that domestic abuse is not about arguments, short tempers and violent tendencies. It’s about domination and control. Men who kill their female partners usually dominate them first – sometimes without physical violence. Indeed, for 28% to 33% of victims, the homicide or attempted homicide was the first act of physical violence in the relationship. Most state...
