Twenty years ago, fresh out of graduate school and recently married, John and Colleen Marzluff left Arizona for a small cabin in the mountains of western Maine. Their mission: to conduct the first-ever extensive study of the winter ecology of the Common Raven under the tutelage of biologist Bernd Heinrich. Drawing on field notes and personal diaries, they vividly and eloquently chronicle their three-year endeavor to research a mysterious and often misunderstood bird—assembling a gigantic aviary, climbing sentry trees, building bird blinds in the forest, capturing and sustaining ravens as study subjects, and enduring harsh Maine winters in pursuit of their goal. They also shared the unique challenges and joys of raising, training, and racing the sled dogs that assisted them in their work.

7 ways to be great at dating, according to science
Since time immemorial, human beings have lusted, loved, bonded, betrayed and broken up. Although the need for love is ubiquitous and universal, how we love is changing fundamentally, as anthropologist Helen Fisher and I discussed in The Internet has increased the pool of possible mates exponentially, giving us an unprecedented proliferation of choices.
The science of dating and matchmaking provides many fascinating illustrations and examples for the study and development of communications, personality, relationships and behaviour. Like body language, many aspects of effective dating and 'chat-up' communications apply to successful communications in general. We tend to be concerned about ourselves, but the other person's needs, feelings and reactions are central to being successful. Some of these principles, and other specific findings relating to forming early successful relationships in dating, are illustrated in the summary below of the study carried out in April by Professor Richard Wiseman of the University of Hertfordshire, as part of the Edinburgh International Science Festival. These lessons are in essence transferable to all relationships and one-to-one meetings, aside from providing many useful dating pointers.
