The most well-known version of this illusion is known as the stopped-clock illusion, wherein a subject's first impression of the second-hand movement of an analog clock, subsequent to one's directed attention (i.e., saccade) to the clock, is the perception of a slower-than-normal second-hand movement rate (the second-hand of the clock may ...
Insects that live under the water have different strategies for dealing with freezing than terrestrial insects do. Many insect species survive winter not as adults on land, but as larvae underneath the surface of the water. Under the water many benthic invertebrates will experience some subfreezing temperatures, especially in small streams.
The photoreceptor cells R1-R6 express the opsin Rh1, [145] which absorbs maximally blue light (around 480 nm), [146] [147] [148] however the R1-R6 cells cover a broader range of the spectrum than an opsin would allow due to a sensitising pigment [149] [150] that adds two sensitivity maxima in the UV-range (355 and 370 nm).

The presence of female flies eating or ovipositing on a carcass may attract other female flies to do the same, perhaps through chemical cues. [12] Females exhibit preference for certain oviposition conditions over others; they attempt to maximize the survival potential of their offspring by laying eggs in only the best places.
Despite the occasional pilot informing passengers (proudly) of an intention to “make up time in the air,” people usually assume planes are going as fast as they safely can, like a speed limit ...
Relative velocity time dilation is where time moves slower as you move faster. The classic example of this is the twin scenario . One twin blasts off in a spaceship traveling close to the speed of ...
Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/ [1] [2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.
A time slower than 8.6 seconds on the test suggests a person may be at risk for falls or hospital admissions, according to one 2005 study. Still, she said there are things I can do to fortify my ...
