When scientific terms become part of the cultural fabric they often lose their meaning. Biology has had its share of modern misunderstandings with 'evolution' becoming colloquial rather than scientific, along with the general term 'theory', which today is used by anyone with a crackpot notion about particle physics, math or the end of the world due to a tunnel in Switzerland.

So it goes. That's why today we have advertising claims like 'the next evolution in cars' and then press releases about the 'missing link' in comets.

Hey, we don't shape the culture, we just try to cut through it. So this time we will talk about the 'missing link' between an Oort cloud and Halley's comet and discuss the 'evolution' of these mysterious space bodies, which will make biologists here irritated. Later on we can use terms like 'genesis' and 'creation' in their place so religious folks can feel slighted also.

Why mention all that? Well, we run out of science terms to use when there is no previous explanation for an object, so we have to fall back on cultural ones in order to convey why something is important. In this instance, a team of scientists has found an unusual object whose backward and tilted orbit around the Sun is just baffling enough that it may tell us about the origins of some comets.

You heard me. Researchers from the Canada-France Ecliptic Plane Survey project have discovered an object that orbits around the Sun -- backwards. And it is tilted at an angle of 104 degrees, almost perpendicular to the orbits of the planets. Take a look:

To some on the fringes, the only good planet is one without people. To some pseudo-environmentalists, a good planet is one where theirs is the only SUV. To millions more, nature is a way to escape the rigors of city life and enjoy the outdoors without being intrusive.

Ecotourism is big business these days. Convincing society that nature's beauty should be preserved and enjoyed has convinced more people than ever they should actually enjoy it.

But an examination of Californian forests says that hiking, bird-watching and other low-impact activities are linked to a sharp drop in carnivores like bobcats and coyotes. In other words, if you really care about Mother Earth you should leave nature to conservationists who get paid to monitor wildlife and instead walk around the local mall.

Sauna has long been a cottage industry in Finland and the entire Northern hemisphere, with Scandinavians and Russians claiming to have used saunas for cleansing and relaxation for over 2,500 years.

Saunas are the new Prius, with various studies claiming a positive influence on general health.

A recent study(1) conducted in 41 healthy volunteers and presented in Dermatology says that regular sauna also has a positive effect on skin physiology.
