Real-mode programs freely execute CLI and STI to control interrupts, PUSHF and POPF to manipulate flags, INT n for DOS and BIOS calls, and IN/OUT for hardware I/O. In normal protected mode, these instructions are privilege-checked -- they execute normally if the caller has sufficient privilege, and fault otherwise. The 386 can't simply let V86 tasks execute them freely -- a DOS program disabling interrupts would bring down the whole system -- but trapping on every INT 21h call would make V86 impractically slow.
Donald Trump has spent much of his second term at war with science and scientists. He is cutting staff at institutions such as the Environmental Protection Agency (EPA) by a third, and has cancelled or frozen up to 8,000 federal research grants. This hasn’t just hurt individual research programmes, it has damaged America’s credibility as a reliable partner in the scientific community. It is not surprising that many researchers – one poll last year by the journal Nature gave the number of 75% – say they are considering leaving the US entirely.
