Walgreens and three other pharmacy chains are suing drugmaker Bausch Health, its subsidiaries and a separate generic drugmaker for allegedly colluding on a deal that allowed the brand-name companies to maintain a longer monopoly of the diabetes drug Glumetza. The alleged deal resulted in those companies jacking up the price of the drug from $350 to more than $3,000 for a 30-day supply.

Why it matters: When combined with similar lawsuits from employer groups, the suing parties are looking to recoup more than $10 billion in overcharges from this antitrust case — another in a long line of infamous "pay-for-delay" deals over generic drugs. Bausch has said it intends "to vigorously defend these matters."

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.
