Have Baseball Throwing Injuries In Young Players Gone Up?
The big question in many aspects of medicine is whether there is more of something or if it is simply better diagnosis than in the past.
In youth baseball programs, throwing injuries seem to have gone up despite pitching limits that weren't evident in the past. Professional baseball once used a four-man rotation and there was no consideration at all about pitching for kids.
But a multicenter, national research study says serious pitching injuries requiring surgery have skyrocketed, with one estimate reporting serious throwing injuries are occurring 16 times more often today than just 30 years ago.

Water: Still Not A Great Lubricant
Water in the Earth's upper mantle and crust likely plays a less important role as a lubricant of plate tectonics than previously assumed, according to a paper presented by geoscientists present in the current issue of Nature (13/06/2013) after the examination of water in the mineral olivine.
Laboratory experiments over the past three decades have suggested the presence of water greatly weakens the mechanical strength of the mineral olivine, a key component of the Earth's upper mantle.
In the recent study, led by the Bayerisches Geoinstitut in Bayreuth, the Secondary Ion Mass Spectrometer (SIMS) facility at the Potsdam based GFZ German Research Centre for Geosciences was used to reassess the importance of water in defining the rigidity of olivine.

Pandora's Promise: Director Robert Stone Takes On The Anti-Nuclear Movement
If you respond yes to that, I think you have lost your mind. While I understand the value of an overwhelming force to end a bloody world war, it's also something that can't be unmade. We had opened "Pandora's Box", the belief went.

Gene Patents: Justice Scalia Dissents On High School Science
Amid much discussion about potential implications for the biotech industry, a separate, extremely troubling aspect of this decision has largely slid under the radar: one of the SCOTUS Justices dissented with basic science saying he is "unable to affirm... knowledge or even my own belief" in high school biology

Around The Arctic June 2013
The Arctic is currently primed for rapid and extensive ice loss, unless we see some very unusual weather conditions this Summer.
The state of the ice can be seen in the following series of satellite images from NASA's Earth Observing System Data and Information System - EOSDIS. EOSDIS produces near real-time data and makes images such as the Arctic mosaic and the Near Real Time (Orbit Swath) Images available on the web.
