Physical sciences Astronomy and space sciences millenarianism — a range of eschatological beliefs that cataclysmic or otherwise transformative events would occur on or around 21 December Professional Mayanist scholars stated that no extant classic Maya accounts forecast impending doom, and that the idea that the Long Count calendar ends in misrepresented Maya history and culture,  while astronomers rejected the various proposed doomsday scenarios easily refuted by elementary astronomical observations. Proponents suggest that this contact influenced the development of modern cultures, technologies, and religions. A common claim is that deities from most, if not all, religions are actually extraterrestrial in origin, and that advanced technologies brought to Earth by ancient astronauts were interpreted as evidence of divine status by early humans.
Was he secretly jealous, or did he mistake his fellow hunter for an animal?
MIT neuroscientists have now shown they can influence those judgments by interfering with activity in a specific brain region — a finding that helps reveal how the brain constructs morality.
In the new study, the researchers disrupted activity in the right TPJ by inducing a current in the brain using a magnetic field applied to the scalp. The researchers, led by Rebecca Saxe, MIT assistant professor of brain and cognitive sciences, report their findings in the Proceedings of the National Academy of Sciences the week of March In the new study, the researchers wanted to go beyond fMRI experiments to observe what would happen if they could actually disrupt activity in the right TPJ.
Their success marks a major step forward for the field of moral neuroscience, says Walter Sinnott-Armstrong, professor of philosophy at Duke University. The researchers used a noninvasive technique known as transcranial magnetic stimulation TMS to selectively interfere with brain activity in the right TPJ.
In a second experiment, TMS was applied in milisecond bursts at the moment when the subject was asked to make a moral judgment.
For example, subjects were asked to judge how permissible it is for a man to let his girlfriend walk across a bridge he knows to be unsafe, even if she ends up making it across safely. In such cases, a judgment based solely on the outcome would hold the perpetrator morally blameless, even though it appears he intended to do harm.
In both experiments, the researchers found that when the right TPJ was disrupted, subjects were more likely to judge failed attempts to harm as morally permissible.
The researchers are also doing a study on the role of the right TPJ in judgments of people who are morally lucky or unlucky. For example, a drunk driver who hits and kills a pedestrian is unlucky, compared to an equally drunk driver who makes it home safely, but the unlucky homicidal driver tends to be judged more morally blameworthy.Many homeless children live in unsafe and chaotic environments, , the child is likely to suffer long‐term negative effects, such as ; SAMHSA’s National Registry of Evidence‐Based Programs and Practices, ; Saxe, Ellis, & Kaplow, ).

In well-nourished females, menarche usually .

For example, enter "giraffe" and you'll get back words like "gazellephant" and "gorilldebeest". Victimization indicators mediated the relationship between identifying as a sexual minority and experiencing negative school outcomes, with greater victimization indicators being associated with increased truancy and lower grades, and the extent of mediation differed by gender.
