Xenobots, named after the African clawed frog (Xenopus laevis), are synthetic organisms that are automatically designed by computers to perform some desired function and built by combining together different biological tissues.

Xenobots are less than a 1 millimeter (0.039 inches) wide and composed of just two things: skin cells and heart muscle cells, both of which are derived from stem cells harvested from early (blastula stage) frog embryos. The skin cells provide rigid support and the heart cells act as small motors, contracting and expanding in volume to propel the xenobot forward. The shape of a xenobot's body, and its distribution of skin and heart cells, are automatically designed in simulation to perform a specific task, using a process of trial and error (an evolutionary algorithm). Xenobots have been designed to walk, swim, push pellets, carry payloads, and work together in a swarm to aggregate debris scattered along the surface of their dish into neat piles. They can survive for weeks without food and heal themselves after lacerations.

🔗 Law 🔗 Thailand

In Thailand, lèse-majesté is a crime according to Section 112 of the Thai Criminal Code. It is illegal to defame, insult, or threaten the monarch of Thailand (king, queen, heir-apparent, heir-presumptive, or regent). Modern Thai lèse-majesté law has been on the statute books since 1908. Thailand is the only constitutional monarchy to have strengthened its lèse-majesté law since World War II. With penalties ranging from three to fifteen years imprisonment for each count, it has been described as the "world's harshest lèse majesté law" and "possibly the strictest criminal-defamation law anywhere". Its enforcement has been described as being "in the interest of the palace".^: 134

The law has criminalised acts of insult since 1957. There is substantial room for interpretation, which causes controversy. Broad interpretation of the law reflects the inviolable status of the king, resembling feudal or absolute monarchs. Thailand's Supreme Court decided the law also applies to prior monarchs. Criticism of any privy council member has raised the question whether lèse-majesté applies by association. Even attempting to commit lèse-majesté, making sarcastic comments about the King's pet, and failure to rebuke an offense have been prosecuted as lèse-majesté.

Anyone can file a lèse-majesté complaint, and the police formally investigate all of them. Details of the charges are rarely made public. A Section 112 defendant meets with official obstruction throughout the case. There are months-long pretrial detentions, and courts routinely deny bail to those charged. The United Nations Working Group on Arbitrary Detention determined that the pretrial detention of an alleged lèse-majesté offender violated international human rights law. The courts seem not to recognise the principle of granting defendants the benefit of the doubt. Judges have said accusers did not have to prove the factuality of the alleged lèse-majesté material but only claim it is defamatory. Pleading guilty, then asking for a royal pardon, is seen as the quickest route to freedom for any accused.

Since the 1976 coup, coup makers have regularly cited a surge of alleged lèse-majesté charges as a reason for overthrowing elected governments. This was cited as one of the major reasons for the 2006 coup and that of 2014. In 2006 and 2007, there were notable changes in the trend. Those targeted by lèse-majesté complaints included more average citizens who were given longer jail sentences. Human rights groups condemned its use as a political weapon and a means to restrict freedom. The 2014 junta government granted authority to army courts to prosecute lèse-majesté, which has usually resulted in secret trials and harsh sentences. Prior to the law's revival in 2020, for three years the Thai government often invoked other laws, such as the Computer Crimes Act and sedition laws, to deal with perceived damages and insults to the monarchy. The longest recorded sentence was in 2021: 87 years imprisonment, reduced to 43 years because the defendant pleaded guilty. In 2023, the Supreme Court ordered a female politician from the Move Forward Party to be banned from politics for life due to her alleged lèse-majesté posts on social media.

🔗 Board and table games

18XX is the generic term for a series of board games that, with a few exceptions, recreate the building of railroad corporations during the 19th century; individual games within the series use particular years in the 19th century as their title (usually the date of the start of railway development in the area of the world they cover), or "18" plus a two or more letter geographical designator (such as 18EU for a game set in the European Union). The games 2038, set in the future, and Poseidon and Ur, 1830 BC, both set in ancient history, are also regarded as 18XX titles as their game mechanics and titling nomenclature are similar despite variance from the common railroad/stock-market theme.

The 18XX series has its origins in the game 1829, first produced by Francis Tresham in the mid-1970s. 1829 was chosen as it was the year of the Rainhill Trials. 1830 was produced by Avalon Hill in 1986, and was the first game of the series widely available in the United States; it is seen as the basic 18XX game by the U.S. audience.

In addition to traditionally published games, the 18XX series has spawned self-published variants and games published by low-volume game companies.

With few exceptions (such as 2038), 18XX titles are multiplayer board games without random variables in their game mechanics.

🔗 Athletics

The Fosbury flop is a jumping style used in the track and field sport of high jump. It was popularized and perfected by American athlete Dick Fosbury, whose gold medal in the 1968 Summer Olympics in Mexico City brought it to the world's attention. The flop became the dominant style of the event; before Fosbury, most elite jumpers used the straddle technique, Western Roll, Eastern cut-off, or scissors jump to clear the bar. Though the backwards flop technique had been known for years before Fosbury, landing surfaces had been sandpits or low piles of matting and high jumpers had to land on their feet or at least land carefully to prevent injury. With the advent of deep foam matting, high jumpers were able to be more adventurous in their landing styles and hence more experimental with jumping styles.

🔗 Statistics

A set of dice is nontransitive if it contains three dice, A, B, and C, with the property that A rolls higher than B more than half the time, and B rolls higher than C more than half the time, but it is not true that A rolls higher than C more than half the time. In other words, a set of dice is nontransitive if the binary relation – X rolls a higher number than Y more than half the time – on its elements is not transitive.

It is possible to find sets of dice with the even stronger property that, for each die in the set, there is another die that rolls a higher number than it more than half the time. Using such a set of dice, one can invent games which are biased in ways that people unused to nontransitive dice might not expect (see Example).

The Ringelmann effect is the tendency for individual members of a group to become increasingly less productive as the size of their group increases. This effect, discovered by French agricultural engineer Maximilien Ringelmann (1861–1931), illustrates the inverse relationship that exists between the size of a group and the magnitude of group members’ individual contribution to the completion of a task. While studying the relationship between process loss (i.e., reductions in performance effectiveness or efficiency) and group productivity, Ringelmann (1913) found that having group members work together on a task (e.g., pulling a rope) actually results in significantly less effort than when individual members are acting alone. Ringelmann discovered that as more and more people are added to a group, the group often becomes increasingly inefficient, ultimately violating the notion that group effort and team participation reliably leads to increased effort on behalf of the members.

The analysis of competing hypotheses (ACH) is a methodology for evaluating multiple competing hypotheses for observed data. It was developed by Richards (Dick) J. Heuer, Jr., a 45-year veteran of the Central Intelligence Agency, in the 1970s for use by the Agency. ACH is used by analysts in various fields who make judgments that entail a high risk of error in reasoning. ACH aims to help an analyst overcome, or at least minimize, some of the cognitive limitations that make prescient intelligence analysis so difficult to achieve.

ACH was a step forward in intelligence analysis methodology, but it was first described in relatively informal terms. Producing the best available information from uncertain data remains the goal of researchers, tool-builders, and analysts in industry, academia and government. Their domains include data mining, cognitive psychology and visualization, probability and statistics, etc. Abductive reasoning is an earlier concept with similarities to ACH.

🔗 History of Science 🔗 Sweden

Ytterby (Swedish pronunciation: [ˈʏ̂tːɛrˌbyː]) is a village on the Swedish island of Resarö, in Vaxholm Municipality in the Stockholm archipelago. Today the residential area is dominated by suburban homes.

The Swedish name of the village translates literally into "outer village". Ytterby is the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, and the elements holmium (Ho), scandium (Sc), thulium (Tm), tantalum (Ta), and gadolinium (Gd) were also first discovered there.

Local roads connect Ytterby to county road 274 and hence the mainland. Except for the winter months, passenger ships of the Waxholmsbolaget call at a pier in Ytterby, providing a connection to Vaxholm town and Stockholm. Ytterby is as well served by several local bus lines of the north east SL district, connecting the area directly to Stockholms Östra station.
