๐ Self-Replicating Machines in Fiction
A self-replicating machine is a type of autonomous robot that is capable of reproducing itself autonomously using raw materials found in the environment, thus exhibiting self-replication in a way analogous to that found in nature. Such machines are often featured in works of science fiction.
๐ Bribery of Senior Wehrmacht Officers
From 1933 to the end of the Second World War, high-ranking officers of the Armed Forces of Nazi Germany accepted vast bribes in the form of cash, estates, and tax exemptions in exchange for their loyalty to Nazism. Unlike bribery at lower ranks in the Wehrmacht, which was also widespread, these payments were regularized, technically legal and made with the full knowledge and consent of the leading Nazi figures.
๐ Tree Shaking
In computing, tree shaking is a dead code elimination technique that is applied when optimizing code written in ECMAScript dialects like JavaScript or TypeScript into a single bundle that is loaded by a web browser. Often contrasted with traditional single-library dead code elimination techniques common to minifiers, tree shaking eliminates unused functions from across the bundle by starting at the entry point and only including functions that may be executed. It is succinctly described as "live code inclusion".

๐ 1918 Spanish Flu
The Spanish flu (also known as the 1918 flu pandemic) was an unusually deadly influenza pandemic. Lasting from January 1918 to December 1920, it infected 500ย million peopleโabout a quarter of the world's population at the time. The death toll is estimated to have been anywhere from 17ย million to 50ย million, and possibly as high as 100ย million, making it one of the deadliest pandemics in human history.
To maintain morale, World War I censors minimized early reports of illness and mortality in Germany, the United Kingdom, France, and the United States. Papers were free to report the epidemic's effects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the pandemic's nickname, "Spanish flu". Historical and epidemiological data are inadequate to identify with certainty the pandemic's geographic origin, with varying views as to the origin.
Most influenza outbreaks disproportionately kill the very young and the very old, with a higher survival rate for those in between, but the Spanish flu pandemic resulted in a higher than expected mortality rate for young adults. Scientists offer several possible explanations for the high mortality rate of the 1918 influenza pandemic. Some analyses have shown the virus to be particularly deadly because it triggers a cytokine storm, which ravages the stronger immune system of young adults. In contrast, a 2007 analysis of medical journals from the period of the pandemic found that the viral infection was no more aggressive than previous influenza strains. Instead, malnourishment, overcrowded medical camps and hospitals, and poor hygiene promoted bacterial superinfection. This superinfection killed most of the victims, typically after a somewhat prolonged death bed.
The Spanish flu was the first of two pandemics caused by the H1N1 influenza virus; the second was the swine flu in 2009.

๐ New England's Dark Day
New England's Dark Day occurred on May 19, 1780, when an unusual darkening of the day sky was observed over the New England states and parts of Canada. The primary cause of the event is believed to have been a combination of smoke from forest fires, a thick fog, and cloud cover. The darkness was so complete that candles were required from noon on. It did not disperse until the middle of the next night.

๐ Stick bomb
A stick bomb is a (mechanical) spring-loaded device constructed out of flat sticks woven together under a bending moment. Other names for stick bombs include Chinese stick puzzles, Cobra wave, and frame bombs. Stick bombs are created for fun and as art, not for any practical use.

๐ Copyright Law is 300 years old today.
The Statute of Anne, also known as the Copyright Act 1710 (cited either as 8 Ann. c. 21 or as 8 Ann. c. 19), is an act of the Parliament of Great Britain passed in 1710, which was the first statute to provide for copyright regulated by the government and courts, rather than by private parties.
Prior to the statute's enactment in 1710, copying restrictions were authorized by the Licensing of the Press Act 1662. These restrictions were enforced by the Stationers' Company, a guild of printers given the exclusive power to printโand the responsibility to censorโliterary works. The censorship administered under the Licensing Act led to public protest; as the act had to be renewed at two-year intervals, authors and others sought to prevent its reauthorisation. In 1694, Parliament refused to renew the Licensing Act, ending the Stationers' monopoly and press restrictions.
Over the next 10 years the Stationers repeatedly advocated bills to re-authorize the old licensing system, but Parliament declined to enact them. Faced with this failure, the Stationers decided to emphasise the benefits of licensing to authors rather than publishers, and the Stationers succeeded in getting Parliament to consider a new bill. This bill, which after substantial amendments was granted Royal Assent on 5 April 1710, became known as the Statute of Anne owing to its passage during the reign of Queen Anne. The new law prescribed a copyright term of 14 years, with a provision for renewal for a similar term, during which only the author and the printers to whom they chose to license their works could publish the author's creations. Following this, the work's copyright would expire, with the material falling into the public domain. Despite a period of instability known as the Battle of the Booksellers when the initial copyright terms under the Statute began to expire, the Statute of Anne remained in force until the Copyright Act 1842 replaced it.
The statute is considered a "watershed event in Anglo-American copyright historyย ... transforming what had been the publishers' private law copyright into a public law grant". Under the statute, copyright was for the first time vested in authors rather than publishers; it also included provisions for the public interest, such as a legal deposit scheme. The Statute was an influence on copyright law in several other nations, including the United States, and even in the 21st century is "frequently invoked by modern judges and academics as embodying the utilitarian underpinnings of copyright law".

๐ Marine glass sponge that builds silica skeletons
The Venus' flower basket (Euplectella aspergillum) is a glass sponge in the phylum Porifera. It is a marine sponge found in the deep waters of the Pacific ocean. As other glass sponges, they build their skeletons out of silica, which is of great interest in materials science as they do not require heat to form their glass latices, which in some ways makes their properties superior to manufactured fiber optics. As other sponges, they feed by filtering sea water to capture plankton.
The sponges are often found to house glass sponge shrimp, usually a breeding pair, whom are typically unable to exit the sponge's lattice due to their size. Consequently, they live in and around these sponges, where the shrimp perform a mutuallistic relationship with the sponge until they die. This may have influenced the adoption of the sponge as a symbol of undying love in Japan, where the skeletons of these sponges are presented as nuptial gifts.
