Digging deep: Harnessing the power of soil microbes for more sustainable farming

http://ift.tt/eA8V8J How will the farms of the future feed a projected 9.8 billion people by 2050? A 'smart farm' project marries microbiology and machine learning in an effort to reduce the need for chemical fertilizers and enhance soil carbon uptake, thus improving the long-term viability of the land while increasing crop yields.

'Cold-blooded' pythons make for caring moms

http://ift.tt/eA8V8J The female Southern African python is the first ever egg-laying snake species shown to care for their babies. This comes at great cost to themselves, as they never eat during the breeding period -- with many snakes starving -- and turn their color to black in order to attract more sun while basking to raise their body temperature.

Construction set of magnon logic extended: Magnon spin currents can be controlled via spin valve structure

http://ift.tt/eA8V8J In the emerging field of magnon spintronics, researchers investigate the possibility to transport and process information by means of so-called magnon spin currents. In contrast to electrical currents, on which todays information technology is based, magnon spin currents do not conduct electrical charges but magnetic momenta. These are mediated by magnetic waves, or so-called magnons, which analogous to sound waves propagate through magnetic materials.

Tasty superfood from plant cell cultures

http://ift.tt/eA8V8J Researchers are developing a new and promising method of producing healthy and tasty plant-based food through plant cell culture (PCC) technology rather than field cultivation. The development work was elevated to a whole new level by a study on the nutritional properties of PCCs grown from cloudberry, lingonberry and stoneberry. Their nutritional value was proven to be much higher than anticipated, in addition to having a nice sensory profile.

Mountains become islands: Ecological dangers of increasing land use in East Africa

http://ift.tt/eA8V8J The mountains of East Africa are a treasure trove of biodiversity. However, their ecosystems may be at a higher risk than previously realized. Scientists have discovered that Mount Kilimanjaro is turning into an "ecological island". Agriculture and housing construction have eliminated the natural vegetation that used to serve as a bridge to the surrounding area, enabling the diversity of species to develop to its current levels. Neighboring mountain regions are presumably also being isolated from their surrounding areas.
