Gamma radiation from the Crab and Vela pulsars [PDF]

open access: yes
The young pulsars in Crab and Vela were observed as very efficient emitters of high energy gamma radiation. While their radiation in the radio, optical, and x ray range was always known to differ considerably, the gamma ray emission on a superficial ...

Landscape diversity can promote functional diversity of spider assemblages while habitat characteristics filter for specific traits

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Agricultural landscape simplification due to the loss of semi‐natural habitats can act as an environmental filter for species and their functional traits. Both local‐ and landscape‐level factors can shape community structure; although through different mechanisms.

Cretaceous lacewing larvae with binocular vision demonstrate the convergent evolution of sophisticated simple eyes

open access: yesInsect Science, EarlyView.
We report three ca. 100 million‐year‐old lacewing larvae with extraordinarily large stemmata. One of them additionally has a very wide head, which represents a previously unknown morphology. The arrangement of the stemmata indicates stereoscopic vision in these predatory larvae.
