For democratic elections to be fair, voting districts must have similar sizes. When populations shift, districts need to be redistributed -- a complex and, in many countries, controversial task when political parties attempt to influence redistricting. Mathematicians at the Technical University of Munich (TUM) have now developed a method that allows the efficient calculation of optimally sized voting districts.
A new study by Mizzou education researchers shows that many secondary school science teachers possess climate change misconceptions similar to average Americans.
Neural crest cells (NCC) are multi-potent cells of ectodermal origin that colonize organs, including the gastrointestinal tract, to form the enteric nervous system (ENS) and hematopoietic organs (bone marrow, thymus) where they participate in lymphocyte trafficking. Here, we demonstrate that NCC colonize the spleen during embryogenesis and persist into adulthood. Finally, we identify similar neural-crest derived cells in both the avian and non-human primate spleen, showing evolutionary conservation of these cells.
Evolution is a difficult concept for many students at all levels, however, a study publishing on May 23 in the open access journal PLOS Biology has demonstrated a simple cost-free way to significantly improve students' understanding of evolution at the secondary level: teach genetics before you teach them evolution.
A new study by social psychologist Nilanjana Dasgupta and her Ph.D. student Tara C. Dennehy at the University of Massachusetts Amherst found that early in college, young women in engineering majors felt more confident about their ability, a greater sense of belonging in engineering, more motivated and less anxious if they had a female, but not male, peer mentor.
English and math teachers underestimate the academic abilities of students of color, which in turn has an impact on students' grades and academic expectations, finds a new study by NYU's Steinhardt School of Culture, Education, and Human Development.
Elementary-age students -- primarily African-American, Hispanic and English Language Learners -- developed positive attitudes toward science, less anxiety, and greater self-confidence after participating in an after-school program where they grew fruits and vegetables using soil-less, hydroponic technology.
There is no evidence to suggest enrichment activities run to interest pupils in science, technology, engineering and maths results in significantly higher numbers of teenagers studying these subjects at A-level.
Researchers from Carnegie Mellon University and the University of Chicago have just unveiled a new, state-of-the-art password meter that offers real-time feedback and advice to help people create better passwords.
Reading supportive comments, 'likes' and private messages from social media friends prior to taking a test may help college students who have high levels of test-anxiety significantly reduce their nervousness and improve their scores, a new study by University of Illinois computer science researchers suggests.
