We asked a poet laureate to judge Jaskier's poetry from 'The Witcher'

My former poetry professor called Jaskier an "untalented beginner."

Just like Geralt of Rivia, the real-life poet laureate of Vermont thinks that the bard Jaskier's music from The Witcher is like ordering a pie only to find that there's no filling. Jaskier may be the equivalent of a mediocre pop star on the Continent, but in terms of straightforward poetry here in the real world, his lyrics leave something to be desired.

Why 'The Eternals' will change the MCU forever

Who awaits in Marvel's deep space?

Of all the movies in Marvel's "Phase Four" slate, it's 2020's The Eternals that raises the most questions — and we don't just mean, "Who the heck are the Eternals?" But whatever mysteries that shroud The Eternals, you can bet that this movie is set to change the fabric of the Marvel Cinematic Universe more than anything else on the horizon.

The Witcher Season 2 is still a long ways away, but Netflix is taking an unprecedented approach to expanding the show's fantasy universe. The company recently announced plans for an anime film that will coexist with the ongoing live-action series starring Henry Cavill as Geralt of Rivia.

The Witcher blog Redanian Intelligence initially noted a WGA crediting the show's staff writer Beau DeMayowith's upcoming work on a project called The Witcher: Nightmare of the Wolf, and Netflix confirmed Wednesday via the NX Twitter account that an anime film of that same name was in development.

How exactly will the "anime film" complement the show? Will it include the same characters from the show and the same cast? When will it be available to stream? Are there any books or stories from author Andrzej Sapkowski that it might borrow from? And most importantly, what's the release date for The Witcher: Nightmare of the Wolf?

Here's all of that and more. (And don't worry, The Witcher Season 2 is coming too.)

Let's get into the science.

A lot of people will have already made up their mind about whether humans need dairy in their diet and will be thinking that the answer is obviously “yes” or obviously “no”. But nutrition is based on science not opinion — so, here’s the latest research on the matter.

History repeats itself. That's bad news for the 2020s.

Here are some big-picture predictions.

What will happen in the 2020s? If history is any guide (and there’s good reason to think it is), the outlook isn’t great.

Here are some big-picture predictions: stagnant real wages, faltering standard of living for the lower and middle classes, worsening wealth inequality, more riots and uprisings, ongoing political polarization, more elites competing for limited positions of power, and elites co-opting radical movements.

How effective is the pill?

To test the efficacy of the pill, women were enrolled in studies and instructed to take their pill at the same time every day.

About one-third of women using contraception use the pill. But how effective is it?

There are two types of contraceptive pill – the combined pill, containing estrogen and progestogen, and the progestogen-only pill (often referred to as the mini pill).

While most evidence about pill effectiveness relates to the combined pill, both pill types are quoted as being 93 percent effective in typical use and 99.5 percent effective in perfect use.

So what do these figures mean and how were they derived?
