Synchrotron could help save the Tassie devil
...e-up for time on a synchrotron at least nine hours flying
time from Tasmania more likely further would make the whole thing very difficult, particularly in terms of biosecurity concerns because we would need to transport biological samples between different countries. Dr Church is one of hundreds of sci...
Learning to evolve: With a little help from my ancestors
...y Dr Stone of Sheffield University, skills such as flying
are easy to refine because the innate ability of today's birds depends indirectly on the learning that their ancestors did, which leaves a genetically specified latent memory for flying. The theory has been tested on simple models of brains called ...
Bird sized airplane to fly like a swift
...oing so, the micro airplane can perform optimally, flying
efficiently and highly maneuverable at very high and very low speeds, just like the swift.The students found out that using only four feathers, much less than the bird uses, already provides the wing with sufficient morphing capacity; this feature ma...
Climate change reduces Queensland's bat numbers
...t a quarter of all mammal species and are the only flying
mammals. Bats are declining worldwide and any information about their ecology is crucial to their future management Bats are often excluded from palaeoecological analyses due to their rarity in the fossil record and the difficulty in identifying them...
Gannet population under threat from global warming
... of over 1000km, said Dr Hamer. They compensate by flying
faster to make sure they dont leave their nests for too long, but our research shows theyve hit their limit. They just physically cant increase their speed any further. Until now, gannets have bucked the trend in the North Sea, their breeding succe...
Fruit bats are not 'blind as a bat'

Agonized death throes probable cause of open-mouthed, head-back pose of many dino fossils
... Dinosaurs and their relatives, ranging from the flying
pterosaurs to Tyrannosaurus rex, as well as many early mammals, have been found exhibiting this posture. The explanation usually given by paleontologists is that the dinosaurs died in water and the currents drifted the bones into that position, or th...
Bat flight generates complex aerodynamic tracks
...m because of their nocturnal habits. Most bats eat flying
insects, consuming up to their body weight each night. Their agility and tremendous ability to maneuver in flight is accentuated by their ability to locate prey using an advanced echo-location system, which is basically a sonar operated by ultrasoun...
Flies don't buzz about aimlessly!
...s. Andy Reynolds says, "Our results with freely flying
Drosophila appear to be the first reported example of searching behaviour that is both scale-free and intermittent. This suggests that these behaviours are not part of two different searching strategies, but rather represent a single very effective a...
Eavesdropping nuthatches distinguish danger threats in chickadee alarm calls
...larm calls to warn about predators. When they see flying
raptors birds of prey such as hawks, owls and falcons they issue a soft, high-pitched "seet" call. However, when they see a stationary or perched predator, chickadees use a loud, wide-spectrum chick-a-dee-dee-dee alarm to recruit other birds to ha...
CMU researcher publishes anole lizard findings
...tterns distinctive to each species sort of like a flying
flag and evolutionary biologists study it closely because the anoles fully extend these dewlaps as signals when mating or establishing territory. Biologists have wondered whether anoles species that live in a very similar habitat, such as a tree t...
New research finds people and pigeons see eye to eye
...cessing in honeybees has led to the development of flying
robots and unmanned helicopters, the researchers say. So a software engineer who wants to design a program to help a robot recognize objects can get a leg up from evolution, which has been developing programs for object recognition in animals long ...
