WHAT IF: A Solar Storm Destroyed the Internet?

Solar Storm - NASA

The sun is always showering Earth with a mist of magnetized particles known as solar wind. For the most part, our planet’s magnetic shield blocks this electric wind from doing any real damage to Earth or its inhabitants, instead sending those particles skittering toward the poles and leaving behind a pleasant aurora in their wake. But sometimes, every century or so, that wind escalates into a full-blown solar storm — and, as new research presented at the SIGCOMM 2021 data communication conference warns, the results of such extreme space weather could be catastrophic to our modern way of life.

SCIENCE: CRISPR Is “Not As Safe As We Thought”

Like a molecular ninja, the genome-editing tool CRISPR-Cas9 slices through ultraspecific segments of DNA to cut out unwanted bits of genetic code. It’s a precise and promising method of genetic editing that’s widely used in scientific research. And scientists hope it could one day be used to selectively remove genes that result in medical problems such as HIV, sickle cell disease and cancer. Unfortunately, a new study published today (July 16) in the journal Nature Biotechnology suggests that this day may be further off than expected — and that CRISPR’s cellular swordsmanship may result in much more collateral damage than … Read more
