Sense Ability


Often considered our ‘sixth sense’, proprioception is awareness to movement and body position – using impulses sent to the brain as we navigate our surroundings. It’s a challenge to actually watch this happening inside moving humans, yet in this fruit fly’s almost transparent body (partly highlighted in orange), proprioceptive neurons (purple) bend and stretch in three dimensions as it squirms across a high-powered microscope. A new technique called SCAPE uses fast but gentle ‘sheets’ of laser light to track impulses in communicating cells, finding these signals are synchronised with patterns of squirms – some neurons ‘fire’ when the animal’s body stretched, others when it is compressed. In the future these techniques might peek at cellular machinery driving other physical activities, in healthy and injured cells, and relate the results back to the fly’s genetic relation – us!

Enhanced: The Dolphin Cloud on Jupiter
Image Credit: NASA, Juno, SwRI, MSSS; Processing: Gerald Eichstädt & Avi Solomon


Explanation: Do you see the dolphin-shaped cloud on Jupiter? The cloud was visible last year during perijove 16, the sixteenth time that NASA’s robotic spacecraft Juno passed near Jupiter since it arrived in mid-2016. During each perijove, Juno passes near a slightly different part of Jupiter’s cloud tops. The dolphin shape may be surprising but is not scientifically significant – clouds on Jupiter and Earth are constantly shifting and can temporarily mimic many familiar shapes. The cloud appears in Jupiter’s South Temperate Belt (STB), a band of dark and dropping clouds that rings the planet and also contains Oval BA, dubbed Red Spot Jr. The featured image was digitally processed to enhance color and contrast. Juno’s next swoop near Jupiter – perijove 20 – will occur on late May.

The Amphiareion of Oropos was a sanctuary dedicated in the late 5th century BCE to the hero Amphiaraos, where pilgrims went to seek oracular responses and healing. It became particularly successful during the 4th century BCE, judging from the intensive building at the site. Photo and notes by Vasilis Protopapas.
