ISCOVERSpaced-Out Kids
OK, I realize I’m more than 20 years
late to the party, but I’m finally
catching up on Star Trek: Voyager. In it,
Capt. Kathryn Janeway commands her crew
as the far-flung starship claws its way back
to Earth.
Invariably, when you travel across star
systems hundreds of years in the future,
you’ll come across bizarre nebulas and
Earth-like planets that make you home-
sick. But one factoid mentioned in passing
in the show’s dialogue stuck in my brain:
Earthlings had colonized Mars by 2100.
Huh, I wonder how the Martian immi-
grants thrived? They must have cracked
the mystery of how to have kids in space
— not an easy feat.
As you’ll read in one story in our special
report on the future of fertility, we have a
long way to go to figure out how to repro-
duce off this planet. We already know, at
least in mice, that male and female reproductive
systems have a tough time in the harsh conditions
of space.
We’re still getting a handle on fertility issues
back on this planet, as well. Scientists are explor-
ing ways to use gene editing to remove the cer-
tainty of inherited disease in embryos. Another
group is focused on sequencing our genomes to
better guide us in picking our sexual partners and
having disease-free children. Think of it as genetic
matchmaking.
As we welcome spring — and the birds and
the bees — the quest for the keys to conception,
survival and engagement on another world car-
ries on.Becky Lang,
Editor in ChiefO«
We can’t let May 2019
go by without a look
back a century ago,
at the famous eclipse
that vaulted Einstein
to stardom. We also
look forward to what’s
next after gravitational
waves echoed across
the solar system.1919-^2
