An exploratory correlation claims that ozone levels can lead to lungs similar to the damage of someone who smokes a pack of cigarettes per day for three decades.

Microbial communities living in deep aquatic sediments have adapted to survive on really old food, according to a new study.

Learning how these microorganisms function on old, poor-quality food at a very slow pace could have future uses in biomedical applications such as a technology that could slow down cell metabolism in human organs so they can survive longer during a transplant process.

To better understand how these microorganisms access this food, researchers tested different types of peptidases—digestive enzymes that work to degrade proteins—in sediment cores from the White Oak River estuary in North Carolina.

Ancient pigs went through a complete genomic turnover after they arrived in Europe, according to a new study. They were domesticated in the Near East and logically would genetically resemble the Near East wild boar from which they derived, but they do not.

Instead, they resemble European wild boar.

The work involved sequenced DNA signatures from more than 2,000 ancient pigs including genomes from 63 archaeological pigs collected across the Near East and Europe over the last 10,000 years.

The U.S. Food and Drug Administration is again warning consumers not to purchase, much less drink, a supplement drink sold as a medical treatment that goes by all kinds of interesting names, from Miracle or Master Mineral Solution, Miracle Mineral Supplement, MMS, Chlorine Dioxide (CD) Protocol, Water Purification Solution (WPS) and probably more.

The 'mind-muscle connection'. Ancient lore for bodybuilders, latest buzz for Instragram fitness followers, or more for aesthetes than athletes?

A new analysis in Frontiers in Sports and Active Living suggests that to lift heavier, or longer, it is better to focus on moving the weight itself - not your muscles.

It's a mystery why humans would go to a place even colder during an ice age, and live on giant rats. Yet they did. Most people don't associate Africa with mountain living today, but Ethiopians moved to the Bale Mountains during the Palaeolithic period 45,000 years ago.

At around 4,000 meters above sea level, the Bale Mountains in southern Ethiopia are inhospitable region. There is a low level of oxygen in the air (making activist protests against astronomy by claiming sacred heritage on Mauna Kea in Hawaii even more silly, since it's higher) temperatures fluctuate sharply, and it rains a lot.
