Article of the day for March 25, 2019 is Project E . Project E was a Cold War arrangement under which the United States provided the United Kingdom with nuclear weapons for the Royal Air Force (RAF). It was later expanded to provide warheads to the British Army, and there was a maritime version known as Project N that provided nuclear depth bombs. US personnel retained custody of the weapons, and handled their storage, maintenance and readiness. The first bombers equipped with Project E weapons were Canberras (example pictured). Due to the operational restrictions, and the loss of independence of the British nuclear deterrent, Project E bombs were phased out in the strategic role in 1962, although they still equipped tactical bombers, and were used on the Thor missiles operated by the RAF from 1959 to 1963 under Project Emily.

Article of the day for March 24, 2019 is Hydnum repandum . Hydnum repandum, the hedgehog mushroom, is a fungus of the family Hydnaceae. First described by Carl Linnaeus in 1753, it is the type species of its genus. The cap is dry, colored yellow to light orange to brown, and often develops an irregular shape, especially when crowded. The mushrooms are characterized by spore-bearing structures—in the form of spines rather than gills—which hang down from the underside of the cap. The mushroom tissue is white with a pleasant odor and a spicy or bitter taste. All parts of the mushroom stain orange with age or when bruised. A mycorrhizal fungus, H. repandum is broadly distributed in Europe, Asia and western North America, where it fruits singly or in close groups in coniferous or deciduous woodland. This is a choice edible species, although mature specimens can develop a bitter taste. The mushrooms are sold in local markets of Europe and Canada.

Article of the day for March 23, 2019 is Emesa helmet . The Emesa helmet is an iron Roman cavalry helmet from the early first century AD. Its face mask, covered in a thin sheet of silver, presents the individualised portrait of a face, likely that of its owner. Decorations, some gilded, adorn the head piece. Ornately designed yet highly functional, the helmet was probably intended for both parades and battle. Its delicate covering is too fragile to have been put to use during cavalry tournaments, but the thick iron core would have defended against blows and arrows. It bears acanthus scroll ornamentation, indicating that the helmet may have come from the luxury workshops of Antioch. Confiscated by Syrian police in 1936 soon after looters discovered it amidst a complex of tombs in the modern-day city of Homs, the helmet was eventually restored at the British Museum. It has been exhibited internationally, and is now in the collection of the National Museum of Damascus.
