In the study, 32 people age 55 and older ate about 57 grams of hazelnuts – 2 ounces or about one-third cup – daily for 16 weeks. Results …
A new study by researchers from The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin has shown for the first time in Ireland that a deficiency in vitamin D was associated with a substantial increased risk of depression (+75%) over a four-year follow up period. The findings form part of the largest representative …
First synthesized in a Belgian lab in 1960, illicitly produced fentanyl has swept through U.S. drug markets in waves, the latest beginning in 2013, and has claimed an extraordinary number of lives. The researchers who wrote the report said having a better understanding of whether fentanyl’s deadly spread is being driven by the economic imperatives …
Angela Bearth, Ph.D., ETH Zurich, revisited work previously done on intuitive toxicology in her presentation, “Intuitive toxicology revisited: People’s understanding of toxicological principles and implications for the risk perception of chemicals.” Bearth related consumers’ knowledge about toxicological principles to their risk perceptions and preferences for a variety of consumer products (e.g., cleaning products, medicines, foods). …
“The experiences of students in and out of the classroom are not preparing them for these skills that are needed as adults,” Graesser and colleagues write. This unique set of cognitive and social skills include: Shared understanding: Group members share common goals when solving a new problem. Accountability: The contributions that each member makes are …
