Martin Heinrich Klaproth (1743-1817), a Great, Somewhat Forgotten, Chemist

Thomas Elliot, 1817-1859; a forgotten ophthalmologist.

That man died almost one hundred years ago; he lived in the then remote town of Carli...

Uranium Glass By Barrie Skelcher

The chemistry textbooks tell us that uranium was discovered by the German chemist, Martin Heinrich Klaproth, in 1789, which is perhaps a simplification of the truth. The element was named after the planet Uranus and what Klaproth reported to the Royal Prussian Academy of Science in that year was uranium oxide, which he had separated from the heavy, black mineral known as pitchblende. The elemen...

A failed outburst of H 1743 - 322

We report on a campaign of X-ray and soft γ-ray observations of the black hole candidate H 1743-322 (also named IGR J17464-3213), performed with the RXTE, INTEGRAL and Swift satellites. The source was observed during a short outburst between 2008 October 03 and 2008 November 16. The evolution of the hardness-intensity diagram throughout the outburst is peculiar, in that it does not follow the c...

Secondary syphilis: The great imitator can't be forgotten.

Syphilis is an infection caused by Treponema pallidum, mainly transmitted by sexual contact. Since 2001, primary and secondary syphilis rates started to rise, with an epidemic resurgence. The authors describe an exuberant case of secondary syphilis, presenting with annular and lichen planus-like lesions, as well as one mucocutaneous lesion. Physicians must be aware of syphilis in daily practice...
