Hip fracture rates declined by 31.8% in females and 25% in males between 1985 and 2005, with the largest decrease among individuals aged 55-64 years. The reasons for this decline are unclear, but factors such as overweight and obesity may contribute.
The study found that antibiotic prescription rates for acute respiratory tract infections decreased by 27% among children under 5 years old between 1995-1996 and 2005-2006, while rates remained stable for adults. The shift was attributed to a decline in ambulatory visits for ear infections and initiatives promoting judicious use of ant...

Researchers found that earlier societies used more land for farming due to smaller populations and less incentive to maximize yield, leading to a large-scale burning of forests.
Migratory birds prefer smaller, protected areas over large forest patches for rest stops and food, according to a Purdue University study. Small woodlots can provide essential refuges for birds vulnerable to predators in open habitats.
