New instrument measures supercurrent flow, data has applications in quantum computing      (via sciencedaily.com) 

An extreme-scale nanoscope is beginning to collect data about how pulses of light at trillions of cycles per second can control supercurrents in materials. The instrument could one day help optimize superconducting quantum bits, which are at the heart of quantum computing, a new and developing technology.

Understanding the cryptic role fungi play in ecosystems      (via sciencedaily.com) 

It is estimated that there are approximately 3 to 13 million fungal species on Earth, many of which are microscopic in size. They live in a range of environments such as in soils, inside the tissues of leaves in rainforests, and in deep oceans. Understanding how fungi move across a range of spatial scales is important to understanding ecosystems and has implications for agriculture and human health, according to a new review.

Climate change in the forests of northern Germany      (via sciencedaily.com)     Original source 

More and more trees are suffering the consequences of decades of human-made climate change. The growth of the European beech has so far suffered decline mainly in southern Europe. European beech is Germany's most important native forest tree species and it is most commonly found in Central Europe. A research team has now been able to show that the European beech is suffering from increasing drought stress in summer in northern Germany as well. This climate stress is particularly pronounced at warmer sites, when there is a higher density of these trees together, and on very sandy soils.

Greenland ice sheet: Short-lived ice streams      (via sciencedaily.com)     Original source 

Major ice streams can shut down, shifting rapid ice transport to other parts of the ice sheet, within a few thousand years. This was determined in reconstructions of two ice streams, based on ice-penetrating radar scans of the Greenland ice sheet.

Giant mantle plume reveals Mars is more active than previously thought      (via sciencedaily.com) 

Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. The discovery reveals that Mars, like Earth and Venus, possesses an active interior, which challenges current views on the evolution of the red planet.

Pedestrians choose healthy obstacles over boring pavements      (via sciencedaily.com) 

Up to 78% of walkers would take a more challenging route featuring obstacles such as balancing beams, stepping stones and high steps, research has found. The findings suggest that providing 'Active Landscape' routes in urban areas could help tackle an 'inactivity pandemic' and improve health outcomes.

Living in greener areas is associated with better mental health and less medication use      (via sciencedaily.com)     Original source 

A new study has evaluated the relationship between better mental health and the 3-30-300 green space rule. According to this rule of thumb, everyone should be able to see at least three trees from their home, have 30 percent tree canopy cover in their neighborhood and not live more than 300 meters away from the nearest park or green space.

Complete picture of Arctic sea ice freeze-thaw cycle highlights sea ice response to climate change      (via sciencedaily.com) 

Years of research show that climate change signals are amplified in the Arctic, and that sea ice in this region is sensitive to increases in Arctic warming. Sea ice greatly modifies the exchanges of heat, momentum and mass between the atmosphere and the ocean. So, the timings of the sea ice melt and freeze onsets, as well as the length of the melt and freeze seasons, play a key role in the 'heat budget' of the atmosphere-ice-ocean system.
