In four months, when flower buds spring up from the ground, you may wonder how plants know it’s time to bloom. This question has baffled plant biologists for years. Now, scientists at the University of Wisconsin-Madison have an answer: a gene that functions as an alarm clock to rouse certain plants from a vegetative state in the winter to a flowering state in the spring.
According to the researchers, the findings, published in the Jan. 8 issue of the journal Nature, could lead to new methods for manipulating the productivity of crop plants, as well as a better understanding of how organisms control the fate of their cells.
Most people may not know that some of our favorite salad ingredients - carrots, cabbage, radishes, beets and parsley - take two seasons to flower and produce seeds because we harvest them before they have the chance to flower. These plants, called biennials, require a season of cold to flower.

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...
