Researchers at Washington State University have developed a carbon-negative concrete that is almost as strong as traditional concrete.

The team infused cement with biochar, a type of charcoal made from organic waste, that had been treated with concrete wastewater.

The biochar could absorb up to 23% of its weight in carbon dioxide from the air while retaining a strength comparable to regular cement.

Cement production is responsible for around 8% of global carbon emissions, and the development could significantly reduce emissions. The research was published in Materials Letters.

The whole alpha male concept was observed with wolves in captivity. However, in the wild the social structure is all about family, though still male dominated (I think).

I wonder if this actually works.

This is the greatest pseudoscience silliness of All Time

Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children's or grandchildren's time—when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness." -Carl Sagan

Since we needed to keep reporting in Excel, and there was no budget for a BI tool, we decided to use Python to do all of the heavy lifting and let Excel take care of displaying the data. So with the help of Python and Windows Task Scheduler, we automated the entire process of gathering our data, cleaning it, saving the results, and refreshing the Excel reports.
