No statistically significant difference in professional soccer player injury rates on artificial, natural turf
New research presented today at the 2014 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) found no greater injury risk for athletes playing on artificial playing surfaces.
The use of artificial playing surfaces at sport venues has increased significantly in recent years, primarily due to the advantages of artificial turf over natural grass: longer playing hours, lower maintenance costs and greater resilience to harsh weather conditions.
Despite these advantages, many elite professional soccer teams are reluctant to install artificial turf because of a perception that injuries occur more often on these types of surfaces.
In the study, "Safety of Third Generation Artificial Turf in Male Elite Professional Soccer Players," Italian researchers reviewed injuries involving players in the top Italian football (soccer) league during the 2011-2012 season.
A total of 2,580 hours of play were recorded (1,270 hours on artificial turf and 1,310 on grass). For every 1,000 hours of play there were 23 injuries recorded on artificial surfaces and 20 on grass, with muscle strains being the most common injury (13 on artificial turf, 14 on grass).
The authors of the study do not consider the injury rates between the two surfaces to be statistically significant, as only three injuries per 1,000 hours of play were attributable to artificial surfaces.
The study authors concluded that there are no major differences between the nature and causes of injuries sustained on artificial turf and those that occur on natural grass surfaces.

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...
