Study finds declining sulfur levels
Urbana IL (SPX) May 13, 2016 -
Air pollution legislation to control fossil fuel emissions and the associated acid rain has worked - perhaps leading to the need for sulfur fertilizers for crop production. A University of Illinois study drawing from over 20 years of data shows that sulfur levels in Midwest watersheds and rivers have steadily declined, so much so that farmers may need to consider applying sulfur in the not too d ...

Study: Cooperation, not struggle for survival, drives speciation, evolution
Bern, Switzerland (UPI) May 12, 2016 -
New empirical evidence supports theoretical research that suggests cooperation - not competition - is the main driver of speciation and evolution.
The theory was developed by Roberto Cazzolla Gatti, an associate professor of ecology and biodiversity at Tomsk State University in Russia. It was inspired by the failure of Gause's principle of competitive exclusion to explain what was act ...

Spotlight on our living planet
Paris (ESA) May 12, 2016 -
One of the biggest Earth observation conferences in the world got off to a flying start today as thousands of scientists from around the world gathered in the Czech Republic to present their latest findings on our changing planet. Reflecting the increasing relevance that Earth observation plays in advancing our understanding of our home and in everyday applications, ESA's fifth Living Planet Sym ...

Earth's magnetic heartbeat
Paris (ESA) May 12, 2016 -
With more than two years of measurements by ESA's Swarm satellite trio, changes in the strength of Earth's magnetic field are being mapped in detail. Launched at the end of 2013, Swarm is measuring and untangling the different magnetic signals from Earth's core, mantle, crust, oceans, ionosphere and magnetosphere - an undertaking that will take several years to complete.
Although invisible ...

Surviving evidence of Earth's formative years
Washington DC (SPX) May 13, 2016 -
New work from a team including Carnegie's Hanika Rizo and Richard Carlson, as well as Richard Walker from the University of Maryland, has found material in rock formations that dates back to shortly after Earth formed. The discovery will help scientists understand the processes that shaped our planet's formative period and its internal dynamics over the last 4.5 billion years. It is published by ...

Cosmic dust reveals Earth's ancient atmosphere
Melbourne, Australia (SPX) May 13, 2016 -
Using the oldest fossil micrometeorites - space dust - ever found, Monash University-led research has made a surprising discovery about the chemistry of Earth's atmosphere 2.7 billion years ago.
The findings of a new study published in the journal Nature - led by Dr Andrew Tomkins and a team from the School of Earth, Atmosphere and Environment at Monash, along with scientists from the Aust ...

Scientists take a major leap toward a 'perfect' quantum metamaterial
Berkeley CA (SPX) May 13, 2016 -
Scientists have devised a way to build a "quantum metamaterial" - an engineered material with exotic properties not found in nature - using ultracold atoms trapped in an artificial crystal composed of light. The theoretical work represents a step toward manipulating atoms to transmit information, perform complex simulations or function as powerful sensors.
The research team, led by scienti ...
