Following a large earthquake, the sparsely instrumented Southwest Pacific fails to consistently meet the UNESCO-IOC targets for operational tsunami forecasting. We present a method to improve regional distance tsunami early warning for such sparsely instrumented regions to meet 10-minute and 45-minute operational targets by utilizing novel application of seismic array processing and a hybrid approach combining array methods, W...

Snakes in the family Elapidae largely produce venoms rich in three-finger toxins (3FTx) that bind to the $$\upalpha _1$$ α 1 subunit of nicotinic acetylcholine receptors (nAChRs), impeding ion channel activity. These neurotoxins immobilize the prey by disrupting muscle contraction. Coral snakes of the genus Micrurus are specialist predators who produce many 3FTx, making them an interesting system for examining the coevolution...

Skeletal muscle adaptation to external stimuli, such as regeneration following injury and hypertrophy in response to resistance exercise, are blunted with advanced age. The accumulation of senescent cells, along with defects in myogenic progenitor cell (MPC) proliferation, have been strongly linked as contributing factors to age-associated impairment in muscle adaptation. p53 plays an integral role in all these processes, as u...

The impacts of relying on stored sperm were evaluated in the sailfin molly, Poecilia latipinna . Females reliant on stored sperm had fewer offspring compared to remated females, but offspring size and short‐term growth rate did not differ. Thus, females may use stored sperm in cases such as previous mating with a preferred male, lack of access to mating opportunities during a reproductive cycle, or to maximize egg fertilizatio...

With aging, skeletal muscle plasticity is attenuated in response to exercise. Here, we report that senescent cells, identified using senescence-associated β-galactosidase (SA β-Gal) activity and p21 immunohistochemistry, are very infrequent in resting muscle, but emerge approximately 2 weeks after a bout of resistance exercise in humans. We hypothesized that these cells contribute to blunted hypertrophic potential in old age....

The speartooth shark Glyphis glyphis is a Critically Endangered whaler shark known from a few tropical river systems in northern Australia and Papua New Guinea. There is limited genetic exchange in populations residing in northern Australian rivers that are greater than 100 km apart. In Queensland, the species is only found in the Wenlock and Ducie River that flow into Port Musgrave. Juveniles are confined to upstream reaches...
