Advancing modular quantum information processing      (via sciencedaily.com)     Original source 

A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.

A belly full of jelly      (via sciencedaily.com)     Original source 

For a long time, scientists assumed that jellies (commonly known as jellyfish) were a dead-end food source for predatory fish. However, a team has now discovered that fish in Greenland waters do indeed feed on jellyfish. In two of the analyzed species, they even made up the majority of the food. The results suggest that the role of jellyfish as prey in marine food webs should be reconsidered, especially in regards to the fact that they could be profiting from climate change and spreading farther and farther north.

Ecologists put an insect group on century-old map of biodiversity      (via sciencedaily.com)     Original source 

The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.

Pit-building venom mixers      (via sciencedaily.com)     Original source 

Researchers show that the adaptation of antlions to their ecological niche has also changed their venom. They compared the venom system of antlion and closely related green lacewing larvae. Antlions produce a much more complex venom from three different venom glands than lacewing larvae do. All the venom proteins identified come from the insects themselves, not from symbiotic bacteria. Some of the toxins are new and appear to be unique to antlions. Waiting for their victims in pitfall traps in the sand, antlions can use their venom to immobilize larger prey. The venom therefore plays an important ecological role in adapting to their barren habitat.

Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
