Researchers have discovered a link between premature births and sleep disorders like insomnia and sleep apnea, according to Nature.

  • The study is part of a $100 million investigation of prematurity in California and East Africa called the UCSF Preterm Birth Initiative. Researchers looked at the "records of almost three million births that took place in California between 2007 and 2012" and found 2,300 records of women diagnosed with a sleep disorder like insomnia or sleep apnea. Among them, insomnia increased the risk of preterm birth by 30%; sleep apnea increased the risk by 40%. (Prematurity is defined as being born three weeks or more before full term.)
  • Sleep disorders aren't a direct cause of preterm births. Jennifer Felder, leader of the study and postdoctoral researcher in clinical psychology at UCSF, said that lack of sleep could cause inflammation, which could lead to prematurity.
  • Why it matters: Nature reports that 15 million babies are born prematurely across the globe each year, and 1.1 million will die from complications.

The Pac-12, which includes universities in Arizona, California, Colorado, Oregon, Utah and Washington state, will play football starting Nov. 6, reversing its earlier decision to postpone the season because of the coronavirus pandemic.

Why it matters: The conference's about-face follows a similar move by the Big Ten last week and comes as President Trump has publicly pressured sports to resume despite the ongoing pandemic. The Pac-12 will play a seven-game conference football season, according to ESPN.

Global coronavirus vaccine initiative launches without U.S. or China

A global initiative to ensure equitable distribution of coronavirus vaccines now includes most of the world — but not the U.S., China or Russia.

Why it matters: Assuming one or more vaccines ultimately gain approval, there will be a period of months or even years in which supply lags far behind global demand. The COVAX initiative is an attempt to ensure doses go where they're most needed, rather than simply to countries that can produce or buy them at scale.
