How a cyanobacterium manages iron scarcity makes it the most successful photosynthetic organism on Earth
The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes appr.....»»
Moon waves goodbye to Hera
As ESA's Hera mission for planetary defense departed its homeworld, it looked back to Earth to show the moon orbiting around it. In this sequence of images the terrestrial disk gradually shrinks as the spacecraft recedes away from it, and the moon mo.....»»
Portal to the past: Geologist identifies metamorphic rock as a crucial feature of the ancient Earth"s carbon cycle
If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31. During the Proterozoic Eon—2.5 billion years to 543 million years ago—the sun was still a young star, much dimmer than today,.....»»
Successful demonstration of a commercial cryogenic radio frequency power sensor paves way for quantum computing
Radio frequency (RF) and microwave power measurements are widely used to support applications across space, defense, and communication. These precise measurements enable engineers to accurately characterize waveforms, components, circuits, and system.....»»
Apophis: A new European space mission could get up close with a large asteroid that"s set to brush by Earth
The European Space Agency has given the go-ahead for initial work on a mission to visit an asteroid called (99942) Apophis. If approved at a key meeting next year, the robotic spacecraft, known as the Rapid Apophis Mission for Space Safety (Ramses),.....»»

Geodynamic mantle-flow model explains deformation of continental crust block in North China
Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's continental crust, cratons have remained largely unchanged for billions of years. Although cratons have survived many geological events.....»»
Report reveals how the state of our oceans is intrinsically linked to human health
A study published in the journal One Earth explores how marine biodiversity conservation, human health and well-being are connected. The results suggest that marine protected areas can be good for both planet and people......»»
