Arthur Blackburn

Arthur Blackburn.
Arthur Blackburn (1892–1960) was an Australian soldier, lawyer, politician, and recipient of the Victoria Cross. Enlisting in the Australian Imperial Force in 1914, he fought with his unit for most of the Gallipoli campaign of 1915, during which he was commissioned. On 23 July 1916, during the Battle of Pozières in France, he led four sorties to drive Germans from a strong point using hand grenades and captured 370 yards (340 m) of trench. He fought in the Battle of Mouquet Farm in August, then was evacuated to Australia due to illness. He served as a member of the South Australian parliament in 1918–1921. After the outbreak of World War II, Blackburn led the 2/3rd Machine Gun Battalion during the Syria–Lebanon campaign in 1941, personally accepting the surrender of Damascus. In early 1942, his battalion was deployed to Java in the Dutch East Indies. Captured by the Japanese, Blackburn spent the rest of the war as a prisoner of war. After the war, he served on the Commonwealth Court of Conciliation and Arbitration.

Hurricane Emily (1993)

Hurricane Emily (1993).
Hurricane Emily was the strongest storm of the 1993 Atlantic hurricane season, and caused record flooding in the Outer Banks of North Carolina. The fifth named storm of the season, Emily became a tropical storm on August 25, after becoming nearly stationary southeast of Bermuda. On August 31, the hurricane reached peak winds of 115 mph (185 km/h) on its approach to North Carolina. Part of the eye passed over Hatteras Island in the Outer Banks, but its absolute center remained 23 mi (37 km) offshore. Emily's strong winds coincided with high tides during a full moon, causing severe flooding along the Pamlico Sound. The villages of Avon and Hatteras were inundated, and in Buxton, the floods left behind water marks as high as 10.54 ft (3.21 m). The storm wrecked 553 homes, leaving a quarter of the Cape Hatteras population homeless. Off the coasts of North Carolina and Virginia, three swimmers drowned.

Dementia with Lewy bodies

Dementia with Lewy bodies.
Dementia with Lewy bodies is a common dementia characterized by changes in sleep, behavior, cognition, movement, and automatic bodily functions. Symptoms worsen over time until cognitive decline interferes with normal daily functioning. The core features are REM sleep behavior disorder (in which people act out their dreams), visual hallucinations, marked fluctuations in attention or alertness, and parkinsonism. The exact cause is unknown, but involves deposits of abnormal clumps of protein in the brain, known as Lewy bodies. Gastrointestinal and heart function can be affected. Definitive diagnosis usually requires an autopsy, and a probable diagnosis—based on symptoms and tests—is often missed. Management of the many symptoms is challenging and involves multiple specialties. There is no cure or medication to stop the disease progression. After the suicide of Robin Williams (pictured) in 2014, his autopsy found that diffuse Lewy bodies explained his symptoms.
