| Children who watch lots of TV may have poor bone health later in life Posted: 07 Jul 2016 05:34 AM PDT Consistently watching high levels of television during childhood and adolescence were linked with lower peak bone mass at age 20 years in a recent study. Hours of television watching per week were recorded by parental or self-report at 5, 8, 10, 14, 17 and 20 years of age in 1181 participants. Those who consistently watched ?14 hours/week of television had lower bone mineral content than those who watched less television, even after adjusting for height, body mass, physical activity, calcium intake, vitamin D levels, alcohol, and smoking (all at age 20). |
| Exploring ways to 'coexist with wildlife' Posted: 07 Jul 2016 05:34 AM PDT Although protected areas such as national parks can play a crucial role in conserving wildlife, most species of large carnivores and large herbivores also depend on being able to occupy human-dominated landscapes. This sharing of space is often associated with conflicts between humans and wildlife, and between different groups of humans with divergent interests. In order to achieve a situation that can be described as "coexistence" there is a need to develop a more nuanced and realistic understanding of what this state looks like. |
| Butterflies' wing patterns change with the seasons Posted: 07 Jul 2016 05:34 AM PDT Tropical butterflies adapt to their environment to improve their chances of survival.
