While mellowing with age has often been thought to have positive effects, a Purdue University researcher has shown that doing so could also help you live longer.
Couples with infants who are particularly fussy or difficult typically do just fine as parents – as long as they have a strong marital relationship. A new study found that a couple’s relationship with each other was key in determining how they reacted as parents when faced with a temperamental baby. “When couples with a supportive marital relationship have a difficult baby, they tend to rise to the challenge,” said Sarah Schoppe-Sullivan, co-author of the study and assistant professor of human development and family science at Ohio State University.
Research by Renee Theiss, Jason Kuo and C J Heckman, which has just been published in The Journal of Physiology, throws light on how information is processed in the Central Nervous System (CNS) to drive movement. The findings are relevant to understanding mechanisms underlying movement and disorders such as spinal cord injury and motor neurone disease (ALS). Interneurones in the spinal cord integrate command signals from the brain, with information from the senses, and their own internal pattern generating activities to send appropriate instructions to motorneurones controlling movement. Spinal interneurones exhibit a remarkable variety of firing patterns in response to a pulse of injected current, with important implications for information processing. These patterns range from repetitive to delayed, to bursting and to single spiking.
According to new statistics that would make Bob Vila cringe, the number of injuries from nail guns has almost doubled since 2001. And researchers say that more and more it is do-it-yourselfers who are feeling the pain.
Nail guns typically use compressed air to drive nails into wood. First used by construction workers and professional carpenters, the guns now are sold routinely in hardware stores and home improvement centers.
The Duke researchers said that many injuries caused by nail guns could be prevented by using tools that fire only when the nose piece is depressed before the trigger is pulled. This “sequential” trigger mechanism is designed to prevent rapid, unintentional firing, but it has not been used as much as tools that allow the user to rapidly “bounce fire’ nails.
Grandparents of adopted grandchildren relate to them as an integral part of the family — just as they relate to their biological grandchildren. This was revealed in research conducted at the University of Haifa School of Social Work. This research is unique in the field in that it evaluated adoptive relationships from the viewpoint of grandparents; previous research examined relationships from the viewpoint of parents and children.
