The real urban jungle

The new book 'Urban Ecosystem Ecology' aims to understand the complexities of urban ecosystems and provide solutions for managing their environmental impacts. The book covers topics such as wildlife, water quality, air quality, and climate change, and offers practical guidance on green infrastructure planning and urban forestry.

U of M research finds ovulating women unconsciously buy sexier clothing to outdo attractive women

A study from the University of Minnesota's Carlson School of Management found that ovulating women prefer sexier fashion products when thinking about local, attractive women, to entice a desirable mate. This behavior is not conscious and applies only during the ovulation phase, with no effect on non-ovulating women.
