In 1605, England’s parliament was sitting on a powder keg, literally. Like now, the country was bitterly divided between two factions, with religion at the heart of the schism after the Reformation pitted Protestants and Catholics against each other in a life or death struggle. History tells us that instead of seeking a political solution such as an election, a group of 13 Catholic conspirators plotted to blow up parliament.

Zombies have lurched to the center of Halloween culture, with costumes proliferating as fast as the monsters themselves. This year, you can dress as a zombie prom queen, a zombie doctor – even a zombie rabbit or banana. The rise of the living dead, though, has a surprising link to another recurring October visitor: the influenza virus.

Of all the sounds humans produce, nothing captures our attention quite like a good scream.

They’re a regular feature of horror films, whether it’s Marion Crane’s infamous shower scream in “Psycho” or Chrissie Watkins’ blood-curdling scream at the beginning of “Jaws.”

The cutting-edge method of growing clusters of cells that organize themselves into mini versions of human brains in the lab is gathering more and more attention. These “brain organoids”, made from stem cells, offer unparalleled insights into the human brain, which is notoriously difficult to study.

But some researchers are worried that a form of consciousness might arise in such mini-brains, which are sometimes transplanted into animals. They could at least be sentient to the extent of experiencing pain and suffering from being trapped. If this is true – and before we consider how likely it is – it is absolutely clear in my mind that we must exert a supreme level of caution when considering this issue.

“Witch hunt” – it’s a refrain used to deride everything from impeachment inquiries and sexual assault investigations to allegations of corruption.

Few topics arouse as much interest and controversy as sex. This is hardly surprising. The biological continuance of the species hinges on it – if human beings stopped having sex, there would soon be no more human beings. Popular culture overflows with sex, from cinema to advertising to, yes, even politics. And for many, sex represents one of the most intimate forms of human connection.

Despite its universality, sex and its purpose have been understood very differently by different thinkers. I teach an annual course on sexuality at Indiana University, and this work has provided opportunities to ponder sex from some provocative angles, including the body, the psyche and the spirit.
