Hot Topic Solar System Earth Biosphere
Bellybutton Biomes
Topic: Biosphere
Bacteria cultured from peoples' bellybuttons are providing information about the stability of bacterial communities over time.

Scrubbing Phosphorus
Topic: Biosphere
The purity of unpolluted waters may actually be aiding the survival of an intrusive algae species. Blooms of the freshwater diatom, Didymo, can alter environments by changing the food web.

Life is the Missing Link in Cloud Formation
Topic: Biosphere
A new study reveals bacterial genes that influence sulfur gas flux from seawater. The research could have implications for understanding the role of ocean bacteria in cloud formation.

Greenhouse Oceans
Topic: Biosphere
New research points to mass mortality in the oceans at a time in history when the Earth was experiencing a greenhouse effect. The study shows that the oceans are in a much more delicate balance than previously thought, and could be a warning of things to come.

Beetle Bling
Topic: Biosphere
Brilliant gold- and silver-colored beetles have given optics researchers new insights into the way biology can recreate the appearance of some of nature's most precious metals.

Icebergs Influence on Biology and Climate
Topic: Biosphere
Scientists have discovered that when icebergs cool and dilut the seas, they also raise chlorophyll levels. This may increase the amount of carbon dioxide that is absorbed in the Southern Ocean, and could have global implications for Earth's climate.

New Group of Algae Discovered
Topic: Biosphere
Biologists have discovered a new group of algae living in a variety of marine and freshwater environments. The newly discovered members of our biosphere, dubbed 'rappemonads', could play an important role in the cycling of elements on our planet.

Microbes and the Swirl of the Ocean
Topic: Biosphere
New research shows that microorganisms help control the amount of light that is reflected off ocean surfaces. The amount of light that oceans absorb can have effects on our planet's climate.

Plankton are Key to Earth's Oxygen
Topic: Biosphere
Researchers have provided new information about the role of plankton in the oxygenation of Earth's atmosphere. The study will help scientists better understand the links between life, the environment and the habitability on Earth.

Using Math to Predict Future Extinctions
Topic: Biosphere
A new mathematical model is helping scientists understand the complex interactions within ecological food webs. The model could help astrobiologists understand the future of extinction events on our planet.
