Submission + - Bumblebees (Bombus terrestris) can detect flowers' electric fields (

An anonymous reader writes: Results indicate floral electric fields improve the bees' ability to discriminate between different flowers. When used with visual signals, electrical cues can enhance the bee's memory of floral rewards. Researchers suggest this method of signalling provides rapid and dynamic communication between plants and pollinators..."What the pollen needs to 'know' is when to 'jump' onto the 'vehicle' — the bee — and when to get off it. So it's a selective adhesion type of question," Prof Robert told BBC Nature.

Submission + - Carmack On VR Latency (

An anonymous reader writes: For a while now, John Carmack has been pushing to bring virtual reality technology back to the gaming world. VR was largely abandoned over a decade ago when it became apparent that the hardware just wasn't ready to support it. In 2013, things are different; cheap displays with a high pixel density and powerful processors designed for small systems are making virtual reality a... reality. One of the last obstacles to be conquered is latency — the delay between moving your head and seeing your perspective change in the virtual world. In a lengthy and highly-technical post at #AltDevBlogADay, Carmack has outlined a number of strategies for mitigating and reducing latency. With information and experience like this being shared with the game development community at large, it shouldn't be long until VR makes a permanent place for itself in our gaming lives.

Leveraging always beats prototyping.
