Earth’s Inner Core May Have Started Spinning Other Way: Study

Deep below the surface, the Earth’s inner core may have changed direction, new research suggests.

Far below our feet, a giant may have started moving against us.

Earth’s inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might even be rotating the other way, research suggested on Monday.

Roughly 5,000 kilometers (3,100 miles) below the surface we live on, this “planet within the planet” can spin independently because it floats in the liquid metal outer core.

Exactly how the inner core rotates has been a matter of debate between scientists—and the latest research is expected to prove controversial.

What little is known about the inner core comes from measuring the tiny differences in seismic waves—created by earthquakes or sometimes nuclear explosions—as they pass through the middle of the Earth.

Seeking to track the inner core’s movements, new research published in the journal Nature Geoscience analyzed seismic waves from repeating earthquakes over the last six decades.

The study’s authors, Xiaodong Song and Yi Yang of China’s Peking University, said they found that the inner core’s rotation “came to near halt around 2009 and then turned in an opposite direction”.

“We believe the inner core rotates, relative to the Earth’s surface, back and forth, like a swing,” they told AFP.

“One cycle of the swing is about seven decades”, meaning it changes direction roughly every 35 years, they added.

They said it previously changed direction in the early 1970s, and predicted the next about-face would be in the mid-2040s.

The researchers said this rotation roughly lines up with changes in what is called the “length of day”—small variations in the exact time it takes Earth to rotate on its axis.

ICE Admits It Has ‘No Records’ For Hundreds Of Thousands Of Illegal Immigrants Released With Electronic Monitors

U.S. Immigration and Customs Enforcement (ICE) admitted it has “no records” of hundreds of thousands of illegal immigrants released into the country with electronic tracking devices, the agency said in a Dec. 22 letter to Syracuse University’s Transactional Records Access Clearinghouse (TRAC).

ICE informed TRAC that it had “no records” of the 377,980 individuals monitored by the agency’s “Alternatives to Detention” (ATD) program used to electronically track illegal immigrants released into the country. TRAC had asked for data via a Freedom of Information Act (FOIA) request on those in ATD custody from the start of fiscal year 2019 to August 2022.

“ICE’s response that they could no longer find records on immigrants in Alternatives to Detention (ATD) that they had previously released came as a shock, particularly after they informed us recently that they had been misleading the public for several months by releasing extremely inaccurate ATD data. The agency really needs to come clean. The American public deserves to have accurate data about the ATD program,” TRAC assistant Professor Austin Kocher told the Daily Caller News Foundation.

ICE started the ATD program in 2004 to monitor illegal migrants released into the country using ankle monitors, GPS tracking and cellphones. With limited detention space, ICE relies on the program to hold those awaiting the years-long backlogs in immigration courts.
