What Does the Sergeant at Arms Do?

In 1981, shortly after Howard Liebengood was elected the 27th Sergeant at Arms of the United States Senate, he realized he had no idea how to address incoming president-elect Ronald Reagan on a visit. “The thought struck me that I didn't know what to call the President-elect,'' Liebengood told The New York Times in November of that year. ''Do you call him 'President-elect,' 'Governor,' or what?” (He went with “Sir.”)

It would not be the first—or last—time someone wondered what, exactly, a Sergeant at Arms (SAA) should be doing. Both the House and the Senate have their own Sergeant at Arms, and their visibility is highest during the State of the Union address. For Donald Trump’s State of the Union on January 30, the 40th Senate SAA, Frank Larkin, will escort the senators to the House Chamber, while the 36th House of Representatives SAA, Paul Irving, will introduce the president (“Mister [or Madam] Speaker, the President of the United States!”). But the job's responsibilities extend far beyond being an emcee.

The Sergeants at Arms are also their respective houses’ chief law enforcement officers. Obliging law enforcement duties means supervising their respective wings of the Capitol and making sure security is tight. The SAA has the authority to find and retrieve errant senators and representatives, to arrest or detain anyone causing disruptions (even for crimes such as bribing representatives), and to control who accesses chambers.

In a sense, they act as the government’s bouncers.

This is not a ceremonial task. In 1988, Senate SAA Henry Giugni led a posse of Capitol police to find, arrest, and corral Republicans missing for a Senate vote. One of them, Republican Senator Bob Packwood of Oregon, had to be carried to the Senate floor to break the filibustering over a vote on senatorial campaign finance reform.

While manhandling wayward politicians sounds fun, it’s more likely the SAAs will be spending their time on administrative tasks. As protocol officer, visits to Congress by the president or other dignitaries have to be coordinated and escorts provided; as executive officer, they provide assistance to their houses of Congress, with the Senate SAA assisting Senate offices with computers, furniture, mail processing, and other logistical support. The two SAAs also alternate serving as chairman of the Capitol Police board.

Perhaps a better question than asking what they do is pondering how they have time to do it all.

What's the Difference Between Mold and Mildew?

We’re all familiar with colorful spots of something growing in our showers and in other dark, damp areas in our homes, but you may not know what to call it. Is it mold, or is it mildew? What is the difference between the two, anyway?

Both terms refer to fungus, but as it happens, it’s a squares-versus-rectangles situation. Mildew is a type of mold. The term typically describes fungi that grows flat, on surfaces like the walls of your shower or window sills. There are also several types of mildew that are specific to plants—powdery mildew and downy mildew are parasites that grow on certain trees, flowers, and crops, for example. While mold might be a colorful green or black, mildew is typically white.

The word mildew originally came from honeydew, a term for sticky secretions aphids and other insects leave on plants, which people used to think came from the sky, like dew. Eventually, the word came to refer to the mold caused by the fungi that fed on these secretions.

Most of the household growths we refer to as mold belong to just a few families of fungi species. According to the CDC, the most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria. Household molds can be a variety of colors, from orange-brown to green to gray to black. (Note that not all mold that is black in color is the more toxic species we call “black mold,” or Stachybotrys.) In contrast to the powdery texture of mildew, molds are typically fuzzy or slimy.

In nature, mold can play an important role in the ecosystem, breaking down dead plants and leaves. In your house, those decomposition abilities aren’t quite so welcome. Mold spores fly through the air, and when they land in moist places, they start to grow—whether that’s on food, your ceiling, paper products, wood, carpet, leather, or elsewhere around your house—and in the process, destroy whatever they're growing on. Unlike mildew, most molds grow down into the surface of its habitat, making them more difficult to remove. In porous materials, mold grows into all the empty crevices, which is why it is often impossible to remove all the mold from ceiling tiles (or soft foods like bread).

Getting rid of the unsightly growth in your damp bathroom is more than just a matter of aesthetics. Indoor mold can cause allergic reactions, such as a stuffy nose or itchy eyes, and can lead to infections for people with compromised immune systems. Some people are more sensitive to mold than others, and may experience more symptoms when exposed to it. Generally speaking, though, mold spores are everywhere, so you’re never going to live a totally mold-free life. Spores will come into your home through windows, doorways, ventilation and climate control systems, and via your clothing, shoes, and pets.

But there’s only one way to effectively inhibit mold growth at home: Get rid of the moisture. That means fixing leaks, getting better ventilation, and possibly running a dehumidifier, according to the CDC’s recommendations on mold.

What Happens to Films Selected for Preservation by the Library of Congress?

On Wednesday morning, the Library of Congress announced its latest slate of movies selected for permanent safekeeping in the National Film Registry. As always, the picks varied widely. The National Film Registry’s class of 2018 includes Cinderella (1950), My Fair Lady (1964), Jurassic Park (1993), The Shining (1980), Smoke Signals (1998), and the animated short Hair Piece: A Film for Nappy-Headed People (1984), which was produced by Ayoka Chenzira, one of the first black female animators.

Originally established in 1988, the National Film Preservation Act tasks the board with selecting American films that are “culturally, historically, or aesthetically" significant. They can pick up to 25 per year, and the movies must be at least 10 years old. The National Film Preservation Board is made up of representatives from a number of industry organizations, including the Academy of Motion Picture Arts and Sciences, the Directors Guild of America, and the National Society of Film Critics. With the new selections, there are 750 films in the registry.

Selection for the registry is an honor, of course, but what does it mean beyond that? How does the Library of Congress, the U.S. legislature’s storage agency for documents and media, go about preserving movies?

According to Steve Leggett, program coordinator for the National Film Preservation Board, selection implores the Library of Congress to get the best possible copy of the film in its original format and store it in their vaults at the National Audio-Visual Conservation Center in Culpeper, Virginia. This ensures the film will be available to future generations.

For Hollywood movies, the process is usually pretty easy. “We simply ask the studio to donate a copy,” Leggett told Mental Floss in 2015. In some cases, that isn’t even necessary. The Library of Congress has more than 1 million films on file, many of them sent by studios or filmmakers for the sake of copyright registry. When the original Star Wars was selected in 1989, Leggett says, congressional librarians simply checked that the 35 millimeter print submitted with Lucasfilm’s copyright application was in good shape. It was, so no further action was needed.

For older and more esoteric selections like newsreels, silent films, documentaries, and early technical achievements in filmmaking, Leggett says the library often seeks out a copy from the community of preservationists. Universities, private foundations, and hobbyists that preserve old films might get a call from the Library of Congress if they have a good copy of a National Film Registry selection. In rare cases, the library will barter for the film, using redundant materials on its shelves. Other times, it will make a copy or pay the archivist to make a new 35 millimeter copy for them. The Culpeper facility stores nitrate prints, the original film stock for many early movies, in specialty lockers because the material is highly volatile and flammable.

Silent films can be tricky because studios often released, revised, and then re-released versions of the film. When one is selected, Library of Congress archivists collect as many aspects and versions of the film as they can, which might mean contacting several studios and archivists.

Of particular challenge in 2015 was the induction of Symbiopsychotaxiplasm: Take One, William Greaves’s quasi-documentary of his 1968 theatrical project staged in Central Park. The film was screened often through the years, as Greaves gained a cult following. It was released on DVD in 2006, but the National Film Preservation Act specified that the library should seek a copy in the original format, which it didn’t have. Leggett said Greaves’s 1968 original cut was “lost,” but the library worked with the late filmmaker's estate to create a new 35 millimeter version that resembled it.

The Audio-Visual Conservation Center itself, buried on a mountainside, has storage space controlled to stay cool and dry. “A film could survive for hundreds of years there,” Leggett says. He admits the audiovisual center wouldn’t survive a nuclear strike—in the event of World War III, the world might lose its best copy of Buster Keaton’s The General—“but it did survive an earthquake with all materials intact.”
