In the American Civil War, the Union and Confederate armies fought a series of battles as the former sought to capture the city of Atlanta, Georgia. The Confederate general John Bell Hood dissipated his army in a series of bold, but fruitless assaults, and was compelled to evacuate the city, allowing the Union to occupy it on September 2, 1864. This photo shows a roundhouse, following extensive damage from fighting. Photo: George N. Barnard; Restoration: Lise Broer

This close-up photo of a Calliphora hilli blowfly shows facial features that are common to all insects: compound eyes and two antennae (the latter are difficult to see, as many true flies have short antennae which reduces drag). Most insects, except some species of cave crickets, are able to perceive light and dark. Many species have acute vision capable of detecting minute movement, and many are able to detect light in the infrared, ultraviolet and the visible light wavelengths. Photo: JJ Harrison

A tinted lithograph, titled "Embarkation of the sick at Balaklava", shows injured and ill soldiers in the Crimean War boarding boats to take them to hospital facilities. Modern nursing had its roots in the war, as war correspondents for newspapers reported the scandalous treatment of wounded soldiers in the first desperate winter, prompting the pioneering work of women such as Florence Nightingale, Mary Seacole, Frances Margaret Taylor and others.

This natural-colour image shows winter sea ice melting off the eastern coastline of Canada's Baffin Island in summer (the only clouds visible here are along the right edge). Eddies along the coast have fashioned the ice into interlocking swirls, especially near Cumberland Sound (centre). Farther north, the ice is not melting as much. The sea ice retreat captured in this image appears typical of seasonal melt. Since the turn of the 21st century, however, Arctic sea ice extent has declined sharply, experiencing a series of low summertime extents and poor wintertime recoveries.

U.S. Senator Henry Clay gives a speech in the Old Senate Chamber calling for compromise on the issues dividing the United States. The result was the Compromise of 1850, a package of five bills, the first two of which were passed on September 9. Ironically, these led to a breakdown in the spirit of compromise in the years preceding the Civil War, particularly after the deaths of Clay and Daniel Webster. Artist: Peter F. Rothermel; Engraver: Robert Whitechurch; Restoration: Lise Broer and Jujutacular

One example was in October 2009, when Typhoon Melor forced Typhoon Parma (right and left, respectively) to reverse course and head southeast, where it battered the Philippine island of Luzon for a second time.
