""Although a great deal of research has shown that more physically imposing individuals are more likely to acquire power, this work is the first to show that powerful people feel taller than they are," says Michelle M. Duguid, PhD ... In a series of three experiments, the researchers found a definite correlation between feeling powerful and feeling tall, and even suggest that future research may want to examine whether employers should consider placing short high-ranking workers in higher offices to raise their psychological sense of power. "Height is often used as a metaphor for power," Duguid says ... "These findings may be a starting point for exploring the reciprocal relationship between the psychological and physical experiences of power," Duguid says."

According to Ethnologue, of the 115 Indigenous languages spoken in the U.S. today, two are healthy, 34 are in danger, and 79 will go extinct within a generation without serious intervention. In other words, 99% of the Native American languages spoken today are in danger. Despite the Cherokee Nation's efforts, the Cherokee language (ᏣᎳᎩ ᎦᏬᏂᎯᏍᏗ) is on that list. There are 573 federally recognized tribes in the United States, and most are battling language extinction. Since 2008, thanks in part to the Esther Martinez Native American Languages Preservation Act, the Administration for Native Americans (ANA), through a competitive grant process, has allocated approximately $12 million annually to tribes working to preserve their languages. In 2018, only 47 language projects received funding - just 29% of all requests, leaving more than two-thirds of applicants without funding, according to ANA. The Bureau of Indian Education, the Department of Education's Department of Indian Education and the National Science Foundation allocated an estimated additional $5.4 million in language funding in 2018, bringing the grand total of federal dollars for Indigenous language revitalization last year to approximately $17.4 million. Compared to how much the United States spent on exterminating Native languages, that sum is a pittance. At the height of the Indian boarding school era, between 1877 and 1918, the United States allocated $2.81 billion (adjusted for inflation) to support the nation's boarding school infrastructure - an educational system designed to assimilate Indigenous people into white culture and destroy Native languages. Since 2005, however, the federal government has only appropriated approximately $180 million for Indigenous language revitalization. In other words, for every dollar the U.S. government spent on eradicating Native languages in previous centuries, it spent less than 7 cents on revitalizing them in this one.

Prairie dogs have different alarm calls for different predators and can also indicate the size, color, speed, etc of the predator. In fact, it was found that the animals could combine and restructure their calls to describe things they hadn't seen before. This was found by having different breeds of dog (a golden retriever, a husky, a Dalmatian, a cocker spaniel) wander through the prairie dog territory one at a time and recording the resulting alarm calls; the calls highly varied even though the 'predator' was of the same predator class. They also showed different calls when researchers wearing different colored shirts walked through the territory (the same for different heights and walking speeds).
