Karl A Franklin from University Hospital Umeå, Sweden, and a team of Nordic researchers questioned more than sixteen thousand randomly selected people from Sweden, Norway, Iceland, Denmark and Estonia about their childhood and their snoring habits. According to Franklin “A total of 15,556 subjects answered the questions on snoring. Habitual snoring, defined as loud and disturbing snoring at least three nights a week, was reported by 18%”.
Being hospitalised for a respiratory infection before the age of two years, suffering from recurrent ear infections as a child, growing up in a large family and being exposed to a dog at home as a newborn were all independently related to snoring in later life. The authors speculate “These factors may enhance inflammatory processes and thereby alter upper airway anatomy early in life, causing an increased susceptibility for adult snoring”.
As well as the obvious problem of sleep deprivation for snorers and those unfortunate enough to share a room with them, research has also shown that people who snore also run more serious risks. Franklin said, “People who snore run an increased risk of early death and cardiovascular diseases, such as heart attacks or strokes”.
The authors conclude, “These new findings suggest that further knowledge about the early life environment may contribute to the primary prevention of snoring”.

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...
