Before we jump into four essential reads for your Friday morning, I wanted to firstly promote this powerful, compelling essay from Ben Ashwell that we just published.
It’s called “It's time for men to start talking about male infertility. I'll go first.” I know I proudly say all our stories are must-reads, but this one especially falls into that category.
I’m Nick Lucchesi, editor-in-chief at Inverse. I’m glad you’re here.
NASA's Pluto mission just hit a major milestone — The NASA Pluto mission New Horizons on Saturday, April 17, 2021, will pass 50 astronomical units from the Sun on its way out of the Solar System, writes Passant Rabie:
Alan Stern, the principal investigator for one of NASA’s most audacious missions, says this weekend is almost a holiday. “Saturday is like a birthday.”
“But it's more like in your car when the odometer turns some big round numbers, let's say 100,000 kilometers,” Stern tells Inverse.
Stern, New Horizons’ principal investigator, has watched the spacecraft venture further out into the outer Solar System since it launched toward Pluto and points beyond in 2006 and says this old spacecraft still has billions of miles left in it.

Part-human, part-monkey — Chinese and U.S. scientists have taken a big step forward developing human-monkey chimeras that could transform how scientists study disease, reports Sarah Wells:
Our understanding of the human body has skyrocketed in recent decades, opening doors for everything from brain-controlled prosthetics to world-changing mRNA vaccines. But there are still some secrets about the body (and the diseases that plague it) that we just might never know due in large part to ethical barriers they present.
But a U.S. and Chinese research team has just taken a huge step toward unlocking these previously unknowable secrets by developing robust monkey-human chimera (hybrids using genetic material from two different species) embryos that may sidestep ethical dilemmas using human cells with a clever loophole to explore such questions.
From the chimera library:
- Scientists grow human muscles in pig embryos for the first time
- U.S. government lifts moratorium on human-animal chimera research (2016)
- Pig-human chimeras have a “safety switch” to prevent sentience
What you need to know about the B.1.1.7 variant — We know that B.1.1.7 is between 40 and 90 percent more transmissible than the “wild” virus. Now new research explains how deadly it is, reports Katie MacBride:
While the B.1.1.7 variant emerged in December in the United Kingdom, it’s now the cause of most new Covid-19 infections in the United States. As of Monday, there were 20,915 reported cases of the B.1.1.7 variant in the U.S.
Information around the variants feels a bit like the information we were getting at the beginning of the pandemic: We know some facts, we don’t know others, and what we do know could change. There’s a lot of good faith research trying to figure out the characteristics of these new pathogens, and sometimes that information is confusing or even contradictory.
