Researchers at the University of Virginia are developing genetic testing to keep children with undiagnosed Type I diabetes out of emergency rooms, NPR reports.

Why it matters: Almost 50% of all children who develop Type 1 diabetes end up hospitalized in a coma because they didn't know they had the autoimmune disease, per the report.

Type I diabetes is difficult to track genetically because no single gene is responsible, but scientists have identified all the variants and about 90% of the known genetic risk.

  • The genetic test was used to find people at highest risk, followed by periodic blood tests to look for the troubling antibodies. Of the roughly 2,000 kids tested to date, about 60 carry the higher genetic risk.

Yes, but: Most kids with positive Type 1 diabetes results won't get Type 1 diabetes, and half of those who do will not have been detected by a genetic test, due to nongenetic risk factors.

Nuclear free-for-all: The arms control era may be ending

The mushroom clouds over Hiroshima and Nagasaki have remained unreplicated for 75 years in part because the U.S. and Soviet Union — after peering over the ledge into nuclear armageddon — began to negotiate.

Why it matters: The arms control era that began after the Cuban Missile Crisis may now be coming to a close. The next phase could be a nuclear free-for-all.

House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer sent a letter to Postmaster General Louis DeJoy on Thursday calling for the recent Trump appointee to reverse operational changes to the U.S. Postal Service that "threaten the timely delivery of mail" ahead of the 2020 election.

Why it matters: U.S. mail and election infrastructure are facing a test like no other this November, with a record-breaking number of mail-in ballots expected as Americans attempt to vote in the midst of a pandemic.
