The researchers compared wild varieties with traditional corn varieties from across the Americas and with modern improved breeding lines. They identified hundreds of genes that played a role in the transformation of corn from its wild origins to today's cultivated crop and show how that transition was largely achieved by ancient farmers who first domesticated it thousands of years ago.
Last year, the economic value of the U.S. corn crop was $76 billion with U.S. growers producing an estimated 12 billion bushels, more than a third of the world's supply. Corn is the largest production crop worldwide, providing food for billions of people and livestock and critical feedstock for production of biofuels.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
