Hi, I'm Clara Moskowitz, Senior Editor for Space and Physics at Scientific American.
Like many kids, I once dreamed of becoming an astronaut.
While I never made it to space, my work at Scientific American has given me the next best thing,
exploring the cosmos through stories and sharing its wonders with science lovers like you.
When I research a story, I immerse myself in the reporting to bring you an exciting and accurate account.
Over the years, I've covered breathtaking rocket launches,
visited one of the world's highest altitude telescopes in Chile, and even trained for suborbital spaceflight.
Space is vast, beautiful, and full of the unexpected.
Taking a moment to look beyond our daily routines and reflect on its mysteries can be a powerful escape.
Join me on this journey of discovery.

For more than a decade, non-invasive prenatal blood testing,
or NIPT, has been a fairly routine aspect of pregnancy care.
This testing searches a pregnant person's blood for fragments of DNA that have been shed by the placenta.
NIPT is designed to spot chromosomal disorders in the fetus,
but in rare cases, the blood test can detect something else.
Cancer in the parent.
