  Philadelphia PA (SPX) Apr 09, 2019 In the 1950s and early '60s, with the Cold War at its peak, the United States flew U2 spy planes across Europe, the Middle East, and central eastern Asia, taking images of interesting military targets. Though the missions typically connected Point A to Point B, say an air field and an important city, in many cases the camera kept recording between those spots, capturing thousands of photos of the desert, steppes, fields, and villages below. Such a collection can represent a goldmine for landscape ... read more |

 Bristol UK (SPX) Apr 09, 2019 
How long will it take our biosphere to recover from the current climate crisis? It's a question that makes for a sobering examination of Earth's ongoing destruction. And it's to the past, specifically the fossils of a tiny species that went out with the dinosaurs, that scientists have turned for the answer.
Recovering from mass extinction has a "speed limit", they reveal, with gradual patt ... more |

 Lemont IL (SPX) Apr 08, 2019 
While water is perceived to be one of the simplest substances in the world, modeling its behavior on the atomic or molecular level has frustrated scientists for decades. To date, no single model has been able to accurately represent the plethora of water's singular characteristics, including the fact that it is densest at a temperature slightly higher than its melting point.
A new study fr ... more |

 Wurzburg, Germany (SPX) Apr 09, 2019 
Hedges, flowering strips and other seminatural habitats provide food and nesting places for insects and birds in agricultural landscapes. This also has advantages for agriculture: bees, flies, beetles and other animal groups pollinate crops and control pest insects in adjacent fields.
But how much of these habitats is necessary and how should they be arranged to make use of these nature-ba ... more |

 Boulder CO (SPX) Apr 08, 2019 
The solid Earth breathes as volcanoes "exhale" gases like carbon dioxide (CO2) - which are essential in regulating global climate - while carbon ultimately from CO2 returns into the deep Earth when oceanic tectonic plates are forced to descend into the mantle at subduction zones. However, the amount of carbon in the sediments and ocean crust that subducts is poorly constrained, as is the fractio ... more |

 Tempe AZ (SPX) Apr 03, 2019 
Beginning about 60,000 years ago, our species spread across the world occupying a wider range of habitats than any other species. Humans can do this because we can rapidly evolve specialized tools that make life possible in different environments - kayaks in the arctic and fishing weirs in the Amazon. How are we able to do this? Most scholars focus on our intelligence: people are better at causa ... more |

Earth observation satellites play a key role in weather forecasting, climate research, monitoring of the planet's surface and the detection of forest fires. These tasks require satellites to transmit very large amounts of data to the ground for analysis. Today's radio systems are reaching their limits in this area.
Optical transmission methods, however, offer the possibility of sending dat ... more |

 Tallahassee FL (SPX) Apr 03, 2019 
Roughly 430 million years ago, during the Earth's Silurian Period, global oceans were experiencing changes that would seem eerily familiar today. Melting polar ice sheets meant sea levels were steadily rising, and ocean oxygen was falling fast around the world.
At around the same time, a global die-off known among scientists as the Ireviken extinction event devastated scores of ancient spe ... more |

Scientists have made a surprising discovery about how strange bacteria that live in soil and sediment can conduct electricity. The bacteria do so, the researchers determined, through a seamless biological structure never before seen in nature - a structure scientists can co-opt to miniaturize electronics, create powerful-yet-tiny batteries, build pacemakers without wires and develop a host of ot ... more |

 Austin TX (SPX) Apr 09, 2019 
It takes at least 10 million years for life to fully recover after a mass extinction, a speed limit for the recovery of species diversity that is well known among scientists. Explanations for this apparent rule have usually invoked environmental factors, but research led by The University of Texas at Austin links the lag to something different: evolution.
The recovery speed limit has been ... more |

Healthy forests play an crucial role in Earth's ecosystem as growing trees take up carbon from the atmosphere. NASA satellites and airborne missions study forests to see how carbon moves through ecosystems - and now citizen scientists can help investigate this key question as well by using their smartphone to measure tree height.
