When we see animals doing remarkable things, how do we know if we're simply seeing tricks or signs of real intelligence? Are talented animals just obeying commands, or do they have some kind of deeper understanding? One of the biggest challenges for animal researchers is to come up with tests that can distinguish between the two.

In the movies, every crazy old fart needs a cool old car. Jack Nicholson drove a spiffy yellow 1970 Dodge Challenger two-door in 'The Bucket List.' In 'Gran Torino,' the cranky pensioner played by Clint Eastwood not only owned a 1972 GT Sport, he also used to build cars like that at the Ford plant.

The world became more aware that America-despite being the hope of many who have the personal drive and ambition to become part of the "American dream"-is beset by serious operational challenges: a massive and growing national debt, widening social inequality, a cornucopian culture that worships materialism, a financial system given to greedy speculation, and a polarized political system

Now let’s look at the flip side. When a diligent and caring person receives your complaint, they have the power to turn a challenge into a triumph. Through active listening, they demonstrate that your satisfaction is their top priority. They not only seek to solve your problem, but they are dedicated to re-earning your trust, your respect, and keeping your business.

Old media companies will be further challenged in the next 15 years, as a new wave of user-generated content washes over the Internet, thanks to the increasing availability and affordability of portable, digital-based electronic devices. The cameraphones which seemed like such novelties just a few years ago will be in everyone's purse and pocket a few years from now.

I brought a Border Collie back home to Vancouver from Wales - where some of my ancestors are from - and needed to challenge him in other ways than just being my pet. So I investigated sheep herding and took a few lessons, and decided I was probably learning more than my dog!

I just want to do shows because you get to see, over all the seasons, the person grow, and you get to grow with the character. That transformation, for me, is what I love about my job. I get to learn about myself and challenge myself and grow with the character. For me, it's a whole process of learning and growing.

More than half of people who leave their jobs do so because of their relationship with their boss. Smart companies make certain their managers know how to balance being professional with being human. These are the bosses who celebrate an employee's success, empathize with those going through hard times, and challenge people, even when it hurts.

“The phaenomena afforded by trades, are a part of the history of nature, and therefore may both challenge the naturalist's curiosity and add to his knowledge, Nor will it suffice to justify learned men in the neglect and contempt of this part of natural history, that the men, from whom it must be learned, are illiterate mechanicks... is indeed childish, and too unworthy of a philosopher, to be worthy of an honest answer.”

“I think that was a concern early on. But I think one of the things that we found after we actually used this system in Perth is that the speed of the technology to get the call, there really is no chance for the gamesmanship. In Perth, we were averaging around five seconds from challenge to display. What we found in observing and also players recognize this, I was actually in some conversations I had with Taylor Dent, he noticed that this technology actually speeded up play rather than slowed play down. There was less reason or no reason to argue with the chair umpire. The players, once they saw the call, just went back and played. The two incorrect challenge limit kind of is a built-in safety net in case anybody tries to abuse the system. I think the concerns now for a player using it for gamesmanship is minimal.”
