  • The implications of this change in the inner core’s movement for Earth’s surface can only be speculated. Vidale said the backtracking of the inner core may alter the length of a day by fractions of a second: “It’s very hard to notice, on the order of a thousandth of a second, almost lost in the noise of the churning oceans and atmosphere.”

    The USC scientists’ future research aspires to chart the trajectory of the inner core in even greater detail to reveal exactly why it is shifting.

    “The dance of the inner core might be even more lively than we know so far,” Vidale said.





  • The actual total two-way communication distance between Zhang and his patient was more than 20,000km, a considerable challenge since longer distances can cause more latency, or delay, between the surgeon’s console in one location, and the response of the robotic arms at the other location.

    In this case, China’s 5G telecommunication network helped to lower the delay to a 135 millisecond latency, less that the 200 millisecond latency that various studies have identified as ideal for telesurgery.

    I never would have guessed Cyber Surgeon could be on the Work From Home bingo card.









  • So, it’s clear that a small subpopulation is preferentially tweeting links to sources of misinformation, and for many users, they’re the most significant source of exposure to these sites. So who are these people?

    They’re a bit more likely to be female. While both the comparison groups were roughly evenly split between male and female, the superspreaders were 60 percent female. They’re also older, on average 58 years old, nearly 20 years older than the sample as a whole. And, while much of the misinformation about the election largely circulated within Republican circles, only 64 percent of the superspreaders were registered Republicans (nearly 20 percent were registered as Democrats).
