People are slaughtering orangutans and wiping them out

Genetics - чт, 2018-02-15 19:00
The population of Bornean orangutans fell by almost half in just 16 years, and it was not a sad by-product of deforestation: many apes were killed deliberately

Bats’ hairy tongues are perfectly adapted for lapping up nectar

Genetically modified organisms (GMO) - чт, 2018-02-15 17:30
If you're a greedy bat, it helps to have a hairy tongue. The hairs will ensure that you can slurp as much nectar as possible from flowers into your mouth

How Google and Facebook hooked us – and how to break the habit

Big tech companies avoid taxes and have taken over our lives and created monopolies – but what can we do about it and how much change do we really want?

Fruit flies are multistable geniuses

PLOS Biology (new articles) - чт, 2018-02-15 00:00

by Christopher C. Pack, Jamie C. Theobald

Our sensory systems have evolved to provide us with information about the external world. Such information is useful only insofar as it leads to actions that enhance fitness, and thus, the link between sensation and action has been thoroughly studied in many species. In insects, for example, specific visual stimuli lead to highly stereotyped responses. In contrast, humans can exhibit a wide range of responses to the same stimulus, as occurs most notably in the phenomenon of multistable perception. On this basis, one might think that humans have a fundamentally different way of generating actions from sensory inputs, but Toepfer et al. show that flies show evidence of multistable perception as well. Specifically, when confronted with a sensory stimulus that can yield different motor responses, flies switch from one response to another with temporal dynamics that are similar to those of humans and other animals. This suggests that the mechanisms that give rise to the rich repertoire of sensory experience in humans have correlates in much simpler nervous systems.
