The effects of temperature and body mass on jump performance of the locust Locusta migratoria. [PDF]

open access: yesPLoS ONE, 2013
Locusts jump by rapidly releasing energy from cuticular springs built into the hind femur that deform when the femur muscle contracts. This study is the first to examine the effect of temperature on jump energy at each life stage of any orthopteran ...

Indirect Ballistic Injury Resulting in Non–ST-Segment Elevation Myocardial Infarction [PDF]

open access: yesJACC: Case Reports
Gunshot-related myocardial injuries typically result from direct penetrating injury by the traversing bullet. We present a case of gunshot-related myocardial injury in the absence of direct penetrating injury to the cardiac structures and describe alternative mechanisms for ballistic-induced injury.
