🔗 Food and drink 🔗 Chemistry

The Maillard reaction ( my-YAR; French: [majaʁ]) is a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. Seared steaks, fried dumplings, cookies and other kinds of biscuits, breads, toasted marshmallows, and many other foods undergo this reaction. It is named after French chemist Louis-Camille Maillard, who first described it in 1912 while attempting to reproduce biological protein synthesis.

The reaction is a form of non-enzymatic browning which typically proceeds rapidly from around 140 to 165 °C (280 to 330 °F). Many recipes call for an oven temperature high enough to ensure that a Maillard reaction occurs. At higher temperatures, caramelization (the browning of sugars, a distinct process) and subsequently pyrolysis (final breakdown leading to burning) become more pronounced.

The reactive carbonyl group of the sugar reacts with the nucleophilic amino group of the amino acid, and forms a complex mixture of poorly characterized molecules responsible for a range of aromas and flavors. This process is accelerated in an alkaline environment (e.g., lye applied to darken pretzels; see lye roll), as the amino groups (RNH₃⁺ → RNH₂) are deprotonated, and hence have an increased nucleophilicity. This reaction is the basis for many of the flavoring industry's recipes. At high temperatures, a probable carcinogen called acrylamide can form. This can be discouraged by heating at a lower temperature, adding asparaginase, or injecting carbon dioxide.

In the cooking process, Maillard reactions can produce hundreds of different flavor compounds depending on the chemical constituents in the food, the temperature, the cooking time, and the presence of air. These compounds, in turn, often break down to form yet more new flavor compounds. Flavor scientists have used the Maillard reaction over the years to make artificial flavors.

🔗 Australia 🔗 Numismatics 🔗 Australia/Western Australia 🔗 Micronations

The Principality of Hutt River, often referred to by its former name, the Hutt River Province, is an unrecognized micronation in Australia. The principality claims to be an independent sovereign state founded on 21 April 1970. The territory is located 517 km (354 mi) north of Perth, near the town of Northampton in the state of Western Australia. It has an area of 75 square kilometres (29 sq mi), making it larger than several independent countries. It is not recognized as a country by the Australian Government or any other national government, and the High Court of Australia and Supreme Court of Western Australia have rejected submissions arguing that it is not subject to Australian laws.

The principality was a regional tourist attraction until it announced it was closed to tourists after 31 January 2020. It issues its own currency, stamps and passports (which are not recognised by the Australian government or any other government). The micronation was founded on 21 April 1970 when Leonard Casley declared his farm to be an independent country, the Hutt River Province. He attempted to secede from Australia over a dispute concerning wheat production quotas. A few years later, Casley began styling himself as "Prince Leonard" and granting family members royal titles, although he did not include the word "principality" in the official name until 2006.

In February 2017, at the age of 91 and after ruling for 45 years, Casley abdicated the throne in favour of his youngest son, Prince Graeme. Leonard Casley died on 13 February 2019.

🔗 Fungi 🔗 Weather 🔗 Weather/Weather

Hair ice, also known as ice wool or frost beard, is a type of ice that forms on dead wood and takes the shape of fine, silky hair. It is somewhat uncommon, and has been reported mostly at latitudes between 45–55 °N in broadleaf forests. The meteorologist and discoverer of continental drift, Alfred Wegener, described hair ice on wet dead wood in 1918, assuming some specific fungi as the catalyst, a theory mostly confirmed by Gerhart Wagner and Christian Mätzler in 2005. In 2015, the fungus Exidiopsis effusa was identified as key to the formation of hair ice.

🔗 Politics 🔗 Pirate Politics 🔗 Sweden 🔗 Politics/Political parties

The Pirate Party (Swedish: Piratpartiet) is a political party in Sweden founded in 2006. Its sudden popularity has given rise to parties with the same name and similar goals in Europe and worldwide, forming the International Pirate Party movement.

The Pirate Party was initially formed to reform laws regarding copyright and patents. The party agenda includes support for strengthening the individual's right to privacy, both on the Internet and in everyday life, and the transparency of state administration. The Pirate Party has intentionally chosen to be bloc independent of the traditional left-right scale to pursue their political agenda with all mainstream parties. The party originally stayed neutral on other matters, but started broadening into other political areas in 2012.

The Pirate Party participated in the 2006 Riksdag elections and gained 0.63% of the votes, making them the third largest party outside parliament. In terms of membership, it passed the Green Party in December 2008, the Left Party in February 2009, the Liberal People's Party and the Christian Democrats in April 2009, and the Centre Party in May 2009, making it, for the time being, the third largest political party in Sweden by membership. The Pirate Party's associated youth organisation, Young Pirate (Swedish: Ung Pirat), was, for a part of 2009 and 2010, the largest political youth organisation in Sweden by membership count.

The Pirate Party came 5th in the 2009 European Parliament elections with 7.13% of the vote and 1 MEP (increasing to 2 after ratification of the Lisbon Treaty). Christian Engström became the first MEP for the party, and Amelia Andersdotter took the second seat on 1 December 2009.

Rick Falkvinge, founder of the party, stepped down on 1 January 2011 after five years as party leader, making vice leader Anna Troberg the party leader.

On 1 December 2014, Anna Troberg announced that she would not be available for re-election in 2015 after her term ended on 31 December 2014.

🔗 Religion 🔗 Classical Greece and Rome 🔗 Greece

The agōgē (Greek: ἀγωγή in Attic Greek, or ἀγωγά, agōgā in Doric Greek) was the rigorous education and training program mandated for all male Spartan citizens, except for the firstborn son in the ruling houses, Eurypontid and Agiad. The training involved cultivating loyalty to the Spartan group, military training (e.g., pain tolerance), hunting, dancing, singing, and social (communicating) preparation. The word agōgē had various meaning in ancient Greek, but in this context it generally meant leading, guidance, or training.

According to folklore, agōgē was introduced by the semi-mythical Spartan law-giver Lycurgus but its origins are thought to be between the 7th and 6th centuries BC when the state trained male citizens from the ages of seven to twenty-one.

The aim of the system was to produce strong and capable warriors to serve the Spartan army. It encouraged conformity and the importance of the Spartan state over one's personal interest and generated the future elites of Sparta. The men would become the "walls of Sparta" because Sparta was the only Greek city with no defensive walls after they had been demolished at the order of Lycurgus. Discipline was strict and the males were encouraged to fight amongst themselves to determine the strongest member of the group.

The agōgē was prestigious throughout the Greek world, and many aristocratic families from other cities vied to send their sons to Sparta to participate in the agōgē for varying periods of time. The Spartans were very selective in which young men they would permit to enroll. Such honors were usually awarded to the próxenoi (πρόξενοι) of Sparta in other cities and to a few other families of supreme ancestry and importance.

🔗 Human rights 🔗 Discrimination 🔗 Organized Labour

International Day to End Violence Against Sex Workers is observed annually on December 17 by sex workers, their advocates, friends, families and allies. Originally conceived as a memorial and vigil for the victims of the Green River Killer in Seattle Washington, United States (US), it has evolved into an annual international event. The day calls attention to hate crimes committed against sex workers worldwide, as well as the need to remove the social stigma and discrimination that have contributed to violence against sex workers and indifference from the communities they are part of. Sex worker activists also state that custom and prohibitionist laws perpetuate such violence.

The inauguration of Joe Biden as the 46th President of the United States took place on January 20, 2021, before noon (EST), marking the commencement of the four-year term of Joe Biden as president and Kamala Harris as vice president. The inaugural ceremony took place on the West Front of the United States Capitol in Washington, D.C. and was the 59th presidential inauguration. Biden took the presidential oath of office, before which Harris took the vice presidential oath of office.

The inauguration took place amidst extraordinary political, public health, economic, and national security crises, including outgoing President Donald Trump's attempts to overturn the 2020 United States presidential election, which incited a storming of the Capitol, Trump's unprecedented second impeachment, and a threat of widespread civil unrest, which stimulated a nationwide law enforcement response. Festivities were sharply curtailed by efforts to prevent the spread of COVID-19 and mitigate the potential for violence near the Capitol. The live audience was limited to members of the 117th United States Congress and, for each, one guest of their choosing, resembling a State of the Union address. Public health measures such as mandatory face coverings, testing, temperature checks, and social distancing were used to protect participants in the ceremony.

"America United" and "Our Determined Democracy: Forging a More Perfect Union"—a reference to the Preamble to the United States Constitution—served as the inaugural themes.

Folding@home (FAH or F@h) is a distributed computing project aimed to help scientists develop new therapeutics for a variety of diseases by the means of simulating protein dynamics. This includes the process of protein folding and the movements of proteins, and is reliant on simulations run on volunteers' personal computers. Folding@home is currently based at the University of Pennsylvania and led by Greg Bowman, a former student of Vijay Pande.

The project utilizes graphics processing units (GPUs), central processing units (CPUs), and ARM processors like those on the Raspberry Pi for distributed computing and scientific research. The project uses statistical simulation methodology that is a paradigm shift from traditional computing methods. As part of the client–server model network architecture, the volunteered machines each receive pieces of a simulation (work units), complete them, and return them to the project's database servers, where the units are compiled into an overall simulation. Volunteers can track their contributions on the Folding@home website, which makes volunteers' participation competitive and encourages long-term involvement.

Folding@home is one of the world's fastest computing systems. With heightened interest in the project as a result of the COVID-19 pandemic, the system achieved a speed of approximately 1.22 exaflops by late March 2020 and reached 2.43 exaflops by April 12, 2020, making it the world's first exaflop computing system. This level of performance from its large-scale computing network has allowed researchers to run computationally costly atomic-level simulations of protein folding thousands of times longer than formerly achieved. Since its launch on October 1, 2000, Folding@home was involved in the production of 226 scientific research papers. Results from the project's simulations agree well with experiments.
