The new study has been prompted by indications from researchers at Australia's Casey Station which suggest the subglacial basins could make the East Antarctic ice sheet more vulnerable in a warming world. Satellite data suggest that the Totten Glacier, which dominates the ice of the Aurora subglacial basin, appears to be losing ice at its downstream edge. " We are getting more science done with...

Correct reproductive timing is crucial for fitness. Breeding phenology even in similar species can differ due to different selective pressures on the timing of reproduction. These selection pressures define species' responses to warming springs. The temporal match-mismatch hypothesis suggests that timing of breeding in animals is selected to match with food availability (synchrony). Alternative...

Carotenoids are synthesized by plants, therefore insects and birds must obtain them from their diet. They function in pigmentation and as antioxidants. We studied the carotenoid profiles in a model food chain (plant-insect-bird) in an air pollution gradient to find out whether heavy metal pollution affects the transfer of carotenoids across the trophic levels. Birch leaves showed higher beta-ca...

The exercise stress test (EST) is the commonest non-invasive test to elucidate the nature of chest pain/discomfort. ST segment depression provides evidence of ischemia, but is hampered by a significant number of false negative and false positive tests. This study evaluated patterns and duration of ST depression in an attempt to differentiate false positive and false negative tests. One hundred ...

We introduce the concept of deformed zero-determinant strategies in repeated games. then show that Tit-for-Tat strategy prisoner’s dilemma game is a strategy, which unilaterally equalizes probability distribution functions payoffs two players.
