Bat flight
dramatically between cancer types. However, the question of whether these differences represent changes in the frequency of chromothripsis between different cell types or changes in the ability of different cell types to survive chromothripsis remains unclear. Finally, additional work will be required to identify the time at which chromothripsis occurs. The micronucleus model of chromothripsis ...
متن کاملBat flight: aerodynamics, kinematics and flight morphology.
Bats evolved the ability of powered flight more than 50 million years ago. The modern bat is an efficient flyer and recent research on bat flight has revealed many intriguing facts. By using particle image velocimetry to visualize wake vortices, both the magnitude and time-history of aerodynamic forces can be estimated. At most speeds the downstroke generates both lift and thrust, whereas the f...
متن کاملAerodynamic performance in bat flight
Bats are the only mammals capable of flight, and they are the only animal flyers that are mammals. This thesis focuses on the latter of those facts, and investigates how bats fly, from an aerodynamic perspective. The data on which this thesis is based were generated by examining the airflows beneath and behind bats flying in a wind tunnel, and by examining their wing kinematics manually and aut...
متن کاملBat Flight and Zoonotic Viruses
Bats are sources of high viral diversity and high-profile zoonotic viruses worldwide. Although apparently not pathogenic in their reservoir hosts, some viruses from bats severely affect other mammals, including humans. Examples include severe acute respiratory syndrome coronaviruses, Ebola and Marburg viruses, and Nipah and Hendra viruses. Factors underlying high viral diversity in bats are the...
متن کاملUnderstanding of bat wing evolution takes flight.
It has long been debated whether the processes and mechanisms responsible for phenotypic variation within a population or between closely related populations can be extrapolated to explain evolutionary trends over longer phylogenetic distances and especially the generation of novel structures. Although there has been great progress in recent years in addressing the genetic basis for microevolut...
