Insect Evolved GEARS to Control Sychronization of Movements During Huge Leaps

…biologists have discovered a precision gearing mechanism that is built and used by an insect known as a planthopper, which is similar to the grasshopper.
The bug employs this device to mechanically synchronize its powerful jumping actuators so that they both fire within 30 microseeconds of each other. It appears that the planthopper developed this device to circumvent timing errors that would be expected to occur if both sides were under independent nervous control.
Just as early fighter planes relied on mechanical synchros to fire their machine guns through their propeller without destroying it, this mechanical timer enables pinpoint directional accuracy when the creature makes leaps of over 100 times its own body length.

Medical Therapies For Treating Vitiligo Skin Disorder

lindaspruillblog:

There are several options available for vitiligo treatment. First of all, understanding how diagnosis of this condition is made is important. The diagnosis is arrived at clinically using distinct signs and symptoms, physical examination findings as well as results from appropriate laboratory tests. Typically, vitiligo is found on sun exposed areas of the body. These  include the face, hands, arms and the feet. In some situations though, other less common areas are involved including the armpits, groin and genitals.

Moreover, another typical symptom is greying of hair in the different parts of the body such as the scalp, beard and eyebrows. The lab test commonly done is skin biopsy. Here, your doctor takes a small sample of skin in the affected area in order to examine it microscopically. This test will show positive results for vitiligo if there is total absence of melanin producing cells in the skin sample.

Treatment of vitiligo is categorized into two main groups. The first is medical therapy where drugs are used to provide treatment. Topical steroid creams are considered for returning the color to de-pigmented areas. Corticosteroids are prescribed by your doctor and are used for a specified period of time in order to achieve positive results. The other option is photo-therapy which makes use of psoralen and ultraviolet A therapy to re-pigment the white patches.

The second group institutes surgical treatment options usually considered after medical therapy has been properly administered. It basically involves skin grafts and transplants which are only given to people approved to have had stable vitiligo for at least three years.

There are also natural means of treating vitiligo in patients whose symptoms are not as severe. You can find more information regarding this natural treatment of vitiligo at www.truthaboutvitiligocure.com.
