Using a series of very technical tests, scientists from the French research facility CEA have determined that the Earth's core is roughly 6,000 degrees Celsius. That is approximately 1,000 degrees hotter than the temperature obtained by tests in the 1990s.
These new figures show that the center of the Earth is just as hot as the surface of the sun.
The experiment that supplied the new temperature used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt. The BBC reported that "To replicate the enormous pressures at the core boundary - more than a million times the pressure at sea level - they used a device called a diamond anvil cell - essentially a tiny sample held between the points of two precision-machined synthetic diamonds.
Once the team's iron samples were subjected to the high pressures and high temperatures using a laser, the scientists used X-ray beams to carry out "diffraction" - bouncing X-rays off of the nuclei of the iron atoms and watching how the pattern changed as the iron changed from solid to liquid."
Teacher shortages and high-turnover rates have become commonly accepted. About two-fifths of teachers quit the profession within five years, according to data released by the Association of Teachers and Lectures (ATL). The main reason for quitting: heavy workloads....

H. Richard Milner is a professor, noted researcher, and expert on race in education at the University of Pittsburgh. Milner believes that “education is the key to addressing inequity and racism in society” and if we are not “working in education to combat racism, we are complicit in maintaining inequity and the status quo...
I recall when teaching an undergraduate course, asking the pre-service teachers in the class to narrow down a chapter on student engagement and management to a single word. Not an easy task, but the group managed to list a series of words that encapsulated the concepts that would make teaching meaningful. Nowhere on the list were terms like assessment, targeted instruction, or remediation. Instead, the list looked this this: Love, Caring, Passion, Connection, Creativity, and Compassion. It...

Ending poverty is our choice. All we need is fortitude; the will to say this will not happen in my community on my watch.
The world is making some progress to end extreme poverty but there is still so much more that needs to be done. One of the most stunning statistics you will find on this global epidemic...
