Maurice of Nassau (1567–1625) was stadtholder of the United Provinces of the Netherlands from 1585 until his death.

On the death of his half-brother Philip William in 1618, he also became the sovereign Prince of Orange.

Pedro II of Brazil
Emperor of Brazil Pedro II was the second and last ruler of the Empire of Brazil, reigning for over 58 years. Born in Rio de Janeiro, his father Pedro I's abrupt abdication and flight to Europe in 1831 left him as Emperor at the age of five. Inheriting an Empire on the verge of disintegration, Pedro II turned Brazil into an emerging power in the international arena. On November 15, 1889, he was overthrown in a coup d'état by a clique of military leaders who declared Brazil a republic. However, he had become weary of emperorship and despaired over the monarchy's future prospects, despite its overwhelming popular support, and did not support any attempt to restore the monarchy.Photo: Mathew Brady/Levin Corbin Handy

Nictitating membrane
The nictitating membrane of a Masked Lapwing as it closes. The membrane is a transparent or translucent third eyelid present in some animals that can be drawn across the eye for protection and to moisten it while maintaining visibility. Some reptiles, birds, sharks, and mammals have full nictitating membranes. Most mammals, however, have a small, vestigial portion of it remaining in the corner of the eye.Photos: 99of9

DNA structural diagram
A diagram showing the structure of DNA, with detail showing the structure of the four bases: adenine, cytosine, guanine and thymine, and the location of the major and minor groove. Along with RNA and proteins, DNA is one of the three major macromolecules that are essential for all known forms of life. Most DNA molecules are double-stranded helices, consisting of two long polymers of simple units called nucleotides, molecules with backbones made of alternating sugars (deoxyribose) and phosphate groups, with the bases attached to the sugars.Image: Richard Wheeler

"God Defend New Zealand" manuscript
The original sheet music for "God Defend New Zealand", one of the two national anthems of New Zealand, the other being "God Save the Queen". Legally they have equal status, but "God Defend New Zealand" is more commonly used, and is popularly referred to as "the national anthem". Originally written as a poem, it was set to music as part of a competition in 1876. Over the years its popularity increased, eventually being named the second national anthem on 21 November 1977. The anthem has lyrics in both English and Māori, with slightly different meanings.Composer: John Joseph Woods; Restoration: SMasters

Sea foam
Sea foam is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter. These compounds can act as surfactants or foaming agents. As the seawater is churned by breaking waves in the surf zone adjacent to the shore, the compounds trap air, forming bubbles which stick to each other through surface tension.Photo: Mbz1
