V8 Carbon Fiber 2017 The Dyson V8 Carbon Fiber is an upgrade version of V8 with a much more powerful motor. The V8 Carbon Fiber produces 155 AW (115 AW on the original V8) in MAX mode. The battery is rated at 40 minutes (same as original V8) in the normal mode. V10 (SV12/SV13/SV27) 2018 The Dyson V10, launched in March 2018, is a successor to ...
Photopsia is the presence of perceived flashes of light in the field of vision. It is most commonly associated with: [4] Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses.
Stellar pulsations are caused by expansions and contractions in the outer layers as a star seeks to maintain equilibrium. These fluctuations in stellar radius cause corresponding changes in the luminosity of the star. Astronomers are able to deduce this mechanism by measuring the spectrum and observing the Doppler effect. [1]
The statement said the "pulsing sound" has stopped. "The crew is asked to contact mission control when they hear sounds originating in the comm system," NASA said. "The speaker feedback Wilmore ...
Tinnitus. Tinnitus is a variety of sound that is heard when no corresponding external sound is present. [1] Nearly everyone experiences faint "normal tinnitus" in a completely quiet room; but it is of concern only if it is bothersome, interferes with normal hearing, or is associated with other problems.

A NASA astronaut at the International Space Station reported hearing strange noises coming from the Boeing Starliner just days before the spacecraft is set to return to Earth.
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [4]
The Dyson V8 is a powerhouse of a vacuum; it’s cordless and features a detachable handle that acts as a second, smaller vacuum perfect for corners or places that are harder to reach with a floor ...
