Receiving touch is of critical importance, as many studies have shown that touch promotes mental and physical well-being. We conducted a pre-registered (PROSPERO: CRD42022304281) systematic review and multilevel meta-analysis encompassing 137 studies in
Most insects and hummingbirds can generate lift during both upstroke and downstroke with a nearly horizontal flapping stroke plane, and perform precise hovering flight. Further, most birds can utilize tails and muscles in wings to actively control the flight performance, while insects control their...
Because of their large ommatidial lenses and wide rhabdoms, some large nocturnal insects with superposition compound eyes, such as hawkmoths, can capture light 4000 times as effectively as photoreceptors in a honeybee’s eye or the human retina, at the same light intensity [50]. Based on ...
Previous analysis on the lateral stability of hovering insects, which reported a destabilizing roll moment due to a lateral gust, has relied on the results of a single wing without considering a presence of the contralateral wing (wing-wing interaction).
Unlike larger insects (such as bumblebees, fruit flies and hawkmoth, Reynolds number <italic>Re</italic> > 100), very-small insects (such as encarsia formosa (EF), frankliniella occidenalis (FO) and anbremia sp. (AS), etc., <italic>Re</italic> &am
In contrast, fruit flies (Drosophila melanogaster) accelerate towards their landing surface and, upon touchdown, use leg forces to undergo nearly instant deceleration8. Legs extend prior to inverted surface landings and upon touchdown legs also assist in body rotation for multiple appendage engagement42...
“hotspot” just north of Rodanthe. The beach once supported herds of rangy cattle standing udder-deep in the surf for relief from the heat and flies. The barrier islands were ideal for raising horses, cattle, and sheep because fencing was cost-prohibitive to early settlers, and the ocean ...
The 1/10th scale mockup above is what I’ve come up with, with images in the mockup as placeholders for where the actual skull/cranium will be placed. I decided on a vertical axis of time covering the past 7 million years, a horizontal axis indicating “evolutionary grade,” a black ...
In the 1990s Black Hawk helicopters were found to have experienced substantial engine performance deterioration from the presence of desert sand (kind of a glassy deposits) on the leading edge of the high-pressure turbine vanes23. The chemistry of the sand analysis revealed the occurrence of calciu...
