United Express Flight 3411 Incident
Template:Infobox Aircraft occurrence The United Express Flight 3411 incident occurred at Chicago O'Hare International Airport, United States on April 9, 2017, when Dr. David Dao Duy Anh, a Vietnamese-American passenger, was injured while being forcibly removed from a fully boarded, sold-out flight to Louisville International Airport. Dao, a pulmonologist and folk musician, refused to surrender his seat when requested because he needed to see patients the following day. Chicago Department of Aviation Security officers were called to remove him from the plane; in the process, they struck Dao's face against an armrest, then pulled him, apparently unconscious, by his arms along the aircraft aisle past rows of onlooking passengers. Prior to the confrontation, United agents offered travel vouchers to passengers to vacate their seats to make room for four deadheading Republic Airways employees, but none of the passengers accepted. United then selected four passengers for involuntary removal from the flight, one of whom was Dao, and the three other passengers agreed to leave. Flight 3411 was operated by Republic Airways on behalf of United Express, a United Airlines regional branch. Video of the incident recorded by passengers went viral on social media, resulting in anger over the force that was used. Politicians expressed concern and called for an official investigation. Then-U.S. President Donald Trump criticized United Airlines, calling its treatment of Dao "horrible." The next morning, then-CEO of United, Oscar Munoz, issued a statement that appeared to justify the removal of Dao, referring to "re-accommodating the customers." Munoz also sent an email to United staff commending the crew's actions for following established procedures and referring to Dao as "disruptive" and "belligerent," though this characterization contradicted passengers' accounts of the incident. Passenger Jason Powell asserted that Dao was not belligerent, saying instead, "He was very polite, matter-of-fact." Cell phone video by passenger Joya Cummings also contradicted Munoz's description of Dao as belligerent. Munoz and United were sharply criticized for their initial statements, and United suffered a drop in its stock price. Two days after the incident, Munoz issued an additional statement, apologizing and promising that such an incident would never again occur on a United aircraft. He said, "No one should ever be mistreated this way." In an ABC television interview, Munoz was asked, "Do you think [Dao] was at fault in any way?" Munoz responded, "No. He can't be. He was a paying passenger sitting on our seat in our aircraft." Munoz's previously planned promotion to become United's chairman was delayed until May 2020 as a result of the incident. Dao reached an "amicable" settlement with United on April 27, 2017, though its terms were not publicly announced.

Germ Line Development
The cells that give rise to the gametes are often set aside during embryonic cleavage. During development, these cells will differentiate into primordial germ cells, migrate to the location of the gonad, and form the germ line of the animal.

Gathas
The Gathas (/ˈɡɑːtəz, -tɑːz/) are 17 Avestan hymns believed to have been composed by Zarathushtra (Zoroaster) himself. They form the core of the Zoroastrian liturgy (the Yasna). They are arranged in five different modes or metres. The Avestan term gāθā (𐬔𐬁𐬚𐬁 "hymn", but also "mode, metre") is cognate with Sanskrit gāthā (गाथा), both from the Proto-Indo-Iranian word *gaHtʰáH, from the root *gaH- "to sing".

Social Bonding and Nurture Kinship
Social Bonding and Nurture Kinship: Compatibility between Cultural and Biological Approaches is a book on human kinship and social behavior by Maximilian Holland, published in 2012. The work synthesizes the perspectives of evolutionary biology, psychology and sociocultural anthropology towards understanding human social bonding and cooperative behavior. It presents a theoretical treatment that many consider to have resolved longstanding questions about the proper place of genetic (or 'blood') connections in human kinship and social relations, and a synthesis that "should inspire more nuanced ventures in applying Darwinian approaches to sociocultural anthropology". The book has been called "A landmark in the field of evolutionary biology" which "gets to the heart of the matter concerning the contentious relationship between kinship categories, genetic relatedness and the prediction of behavior", "places genetic determinism in the correct perspective" and serves as "a shining example of what can be achieved when excellent scholars engage fully across disciplinary boundaries." The aim of the book is to show that "properly interpreted, cultural anthropology approaches (and ethnographic data) and biological approaches are perfectly compatible regarding processes of social bonding in humans." Holland's position is based on demonstrating that the dominant biological theory of social behavior (inclusive fitness theory) is typically misunderstood to predict that genetic ties are necessary for the expression of social behaviors, whereas in fact the theory only implicates genetic associations as necessary for the evolution of social behaviors. Whilst rigorous evolutionary biologists have long understood the distinction between these levels of analysis (see Tinbergen's four questions), past attempts to apply inclusive fitness theory to humans have often overlooked the distinction between evolution and expression. Beyond its central argument, the broader philosophical implications of Holland's work are considered by commentators to be that it both "helps to untangle a long-standing disciplinary muddle" and "clarifies the relationship between biological and sociocultural approaches to human kinship." It is claimed that the book "demonstrates that an alternative non-deterministic interpretation of evolutionary biology is more compatible with actual human social behavior and with the frameworks that sociocultural anthropology employs" and as a consequence, delivers "a convincing, solid and informed blow to the residual genetic determinism that still influences the interpretation of social behaviour."

Extensively Drug-resistant Tuberculosis
Extensively drug-resistant tuberculosis (XDR-TB) is a form of tuberculosis caused by bacteria that are resistant to some of the most effective anti-TB drugs. XDR-TB strains have arisen after the mismanagement of individuals with multidrug-resistant TB (MDR-TB). Almost one in four people in the world is infected with TB bacteria. Only when the bacteria become active do people become ill with TB. Bacteria become active as a result of anything that can reduce the person's immunity, such as HIV, advancing age, or some medical conditions. TB can usually be treated with a course of four standard, or first-line, anti-TB drugs (i.e., isoniazid, rifampin and any fluoroquinolone). If these drugs are misused or mismanaged, multidrug-resistant TB (MDR-TB) can develop. MDR-TB takes longer to treat with second-line drugs (i.e., amikacin, kanamycin, or capreomycin), which are more expensive and have more side-effects. XDR-TB can develop when these second-line drugs are also misused or mismanaged and become ineffective. The World Health Organization (WHO) defines XDR-TB as MDR-TB that is resistant to at least one fluoroquinolone and a second-line injectable drug (amikacin, capreomycin, or kanamycin). XDR-TB raises concerns of a future TB epidemic with restricted treatment options, and jeopardizes the major gains made in TB control and progress on reducing TB deaths among people living with HIV/AIDS. It is therefore vital that TB control be managed properly and new tools developed to prevent, treat and diagnose the disease. The true scale of XDR-TB is unknown as many countries lack the necessary equipment and capacity to accurately diagnose it. By June 2008, 49 countries had confirmed cases of XDR-TB. By the end of 2017, 127 WHO Member States reported a total of 10,800 cases of XDR-TB, and 8.5% of cases of MDR-TB in 2017 were estimated to have been XDR-TB. In August 2019, the Food and Drug Administration (FDA) approved the use of Pretomanid in combination with bedaquiline and linezolid for treating a limited and specific population of adult patients with extensively drug resistant, treatment-intolerant or nonresponsive multidrug resistant pulmonary TB.

Neolithic Subpluvial
The Neolithic Subpluvial, or the Holocene Wet Phase, was an extended period (from about 7500–7000 BCE to about 3500–3000 BCE) of wet and rainy conditions in the climate history of northern Africa. It was both preceded and followed by much drier periods. The Neolithic Subpluvial was the most recent of a number of periods of "Wet Sahara" or "Green Sahara", during which the Sahara region was much moister and supported a richer biota and human population than the present-day desert.

Drydene 311 (Saturday)
The Drydene 311 was a 311-mile (501 km) NASCAR Cup Series stock car race held annually at Dover International Speedway in Dover, Delaware. It was one of two Cup races at the track. The 2007 Autism Speaks 400 presented by Visa marked the first time that a NASCAR Cup race entitlement was dedicated to a non-profit organization, by the race's title sponsor, Visa Inc. Martin Truex Jr. is the defending winner. From 2007 to 2018, the race was named the "Autism Speaks 400 presented by Visa", dedicated to increasing understanding and knowledge of autism spectrum disorders; funding dedicated to eugenics; and advocating for the needs of affected families. Between 2001 and 2006, the race was broadcast in the United States on FX. Television coverage of the race moved to the Fox network beginning in 2007, but after eight years, the race returned to cable television with Fox Sports 1. The 2020 race was postponed to August due to the COVID-19 pandemic and became a doubleheader with the second race. Both events were named the Drydene 311 as their race lengths were shortened.

Secure Access Service Edge (SASE)
SASE is an acronym for Secure Access Service Edge. Coined by analyst firm Gartner, SASE simplifies wide-area networking (WAN) and security by delivering both as a cloud service directly to the source of connection (user, device, branch office, IoT device, edge computing location) rather than the enterprise data center. Security is based around identity, real-time context and enterprise security and compliance policies. An identity may be attached to anything from a person/user to a device, branch office, cloud service, application, IoT system, or an edge computing location . SASE is meant to be a simplified WAN and security solution for a mobile, global workplace that relies on cloud applications and data. The common solution of backhauling all WAN traffic over long distances to one or a few corporate data centers for security functions adds network latency when users and their cloud application are globally dispersed, rather than on-premises . By targeting services to the edge at the connection source, SASE eliminates the latency caused by backhauling.
