Genetic analysis finds greater threat in frog-killing fungus

...aylor. "That means there must be someplace else on earth where this fungus is endemic. One would guess that the frogs living where the ancestral population of this fungus is located would not be affected that badly. We could then try to determine the mechanisms those frogs use to resist the pathogen." Th...

Genomics study provides insight into the evolution of unique human traits

Investigating Life in Extreme Environments report gives hints on facts of life

...ife first appeared and survived on Earth (as early earth was an extreme environment) but it can also give indication for the search for life on other planets. To examine these issues and other matters the European Science Foundation (ESF) has published a 58-page report Investigating Life in Extreme Envir...

The basic notion is very simple: young people have a sense of direction and navigation that we wish to employ in helping them to understand how cells develop and how those cells navigate in three-dimensional space as tissues and ...

Researchers examine carbon capture and storage to combat global warming

... more crucial, Benson said. From the air to the earth In the capture process, carbon dioxide is extracted from a mix of waste gases. The most common method sends the exhaust through a chimney containing a three-dimensional mesh. As the gas goes up, a chemical solvent drizzles down, soaking up the gas...

Scientists propose the kind of chemistry that led to life
