Archaea are a family of single-celled organisms that can thrive in environments like boiling hydrothermal pools and smoking deep sea vents deep underground, which are too extreme for most other species to survive.

It's a story as old as medicine. When it comes to treatments, people don't always obey the written word. When it comes to antibiotics, for example, people may stop taking them when they feel better so they can save them for another incident. 

Prescription medication guidelines are written specifically, to help people get the effect. So why do only 50 patient of patients take prescription medication as they should, 160 years after medicine became a proper field?

Doubling and even nearly tripling saturated fat in diets does not drive up total levels of saturated fat in the blood, according to a controlled diet study.

The researchers found that total saturated fat in the blood did not increase - and went down in most people - despite being increased in the diet when carbohydrates were reduced. Palmitoleic acid, a fatty acid associated with unhealthy metabolism of carbohydrates that can promote disease, went down with low-carb intake and gradually increased as carbs were re-introduced to the study diet.

Retired baseball stars Barry Bonds, Mark McGwire and Rafael Palmeiro each have Hall of Fame-worthy numbers, more than 500 home runs.

Want to improve tomato crop yields without using more fertilizer? Try  verimcompost leachate. That is a soil ameliorant, which is basically a fertilizer but made of an organic liquid produced by earthworm poop. If you are really organic, you can even make tea from it. 

A research project recently studied the effects of vermicompost leachate on tomato seedlings subjected to various temperatures and levels of water stress. 

New findings about carbon deep beneath the Earth's surface suggest it might have influenced the history of life on the planet - and diamonds.

There is little understanding of how carbon behaved deep below the Earth's surface so researchers have created a model to try and calculate how much carbon and what types exist in fluids at 100 miles below the Earth's surface at temperatures up to 2,100 degrees F.
