Sharks use Earths magnetic field as a GPS, scientists say
PORTLAND, Maine (AP) Sharks use the Earth’s magnetic field as a sort of natural GPS to navigate journeys that take them great distances across the world’s oceans, scientists have found.
Researchers said their marine laboratory experiments with a small species of shark confirm long-held speculation that sharks use magnetic fields as aids to navigation behavior observed in other marine animals such as sea turtles.
Their study, published this month in the journal Current Biology, also sheds light on why sharks are able to traverse seas and find their way back to feed, breed and give birth, said marine policy specialist Bryan Keller, one of the study authors.
Migrant Parents Feel Forced to Send Children Across the Border Alone
Many migrants are sending their children to the U.S. alone because those with older children are being rapidly expelled.
Marely traveled for 13 days with her mother from El Salvador toward the U.S.-Mexico border. But once they made it to a raft to cross the Rio Grande, the 12-year-old found out her mother wasn’t coming with her. Marely had to then turn herself in to Border Patrol agents in La Joya, Texas. Her mother is among many migrants sending their children to the U.S. alone because migrant families with older children are being rapidly expelled under a pandemic health rule. Meanwhile if unaccompanied children arrive alone, the Biden administration is allowing them to remain in the U.S. while they wait for their court cases. The Associated Press
