Someone Finally Figured Out How Birds Navigate — They Can See the Earth’s Magnetic Fields

A newly discovered protein in bird’s eyes has shed light on how our winged friends can navigate the planet so well. It turns out this protein gives birds a 6th sense that allows them to “see” the Earth’s magnetic fields.

The Earth’s magnetic fields, thought to be created from deep within the planet’s core, are invisible to most human eyes.

A flow of liquid Earth-core iron generates electric currents which then produce magnetic fields. (The moon also creates a weak magnetic field with its gravitational pull on our salty oceans.)

Stunning new SWARM images have allowed us to see the Earth’s magnetic fields in more clarity than ever, but birds are already more advanced than us at least in one regard. They can see these magnetic fields without any help from scientific instruments.

Even with highly accurate tracking scientists say that the magnetic field is very difficult to pinpoint. “It’s a really tiny magnetic field. It’s about 2-2.5 nanotesla at satellite altitude, which is about 20,000 times weaker than the Earth’s global magnetic field,” Nils Olsen, head of geomagnetism at the Technical University of Denmark says.

However, birds use the Earth’s magnetic fields to guide them around the planet with ease. Scientists discovered this looking at two bird species – robins and zebra finches.

Cry4 a special protein in the lens of birds’ eyes, is in a class of proteins called cryptochromes. They are photoreceptors sensitive to blue light, found in both plants and animals. These proteins play a role in regulating circadian rhythms.

These cryptochromes are also believed to help birds orient themselves in space, giving them what many of us would consider a superpower – magnetoreception. The visual ability to detect magnetic fields may also work due to quantum coherence within the blue light spectrum.

Scientists at Lund University in Sweden confirmed the presence of three of the magnetoreceptive proteins – Cry1, Cry2 and Cry4 – in the bodies of zebra finches, and similar research conducted at Carl von Ossietzky University Oldenburg in Germany, arrived at similar results after studying the presence of Cry4 in robins. The proteins seem to be concentrated in the part of the bird’s eyes that receive a lot of light –meaning that they would navigate better according to circadian rhythms as well.

What’s even more fascinating, is that the scientists who studied finches and robins believe that other animals, perhaps all of them including humans, have magnetic receptors that can pick up on magnetic fields as well. This means we all have an ability to see an “invisible” magnetic field, not just sense it.

Moreover, as research confirms that the Earth’s magnetic fields are likely to flip, we’ll all be just fine. We shouldn’t expect a geomagnetic apocalypse, but we might need to use this 6th sense exemplified in birds’ eyes as a way to navigate ourselves.

Jeff Bezos Thanks Amazon Workers And Customers For Paying For His Flight To Space

The billionaire space race chalked up one more ignoble milestone on July 20 when the world’s richest man, Jeff Bezos, boarded a reusable rocket his company Blue Origin built and funded, flew to the edge of space for a moment of weightlessness, and came back down to earth.

You can watch the flight and learn more about the journey here.

The Amazon founder has faced withering criticism for accumulating his massive fortune on the backs of an exploited workforce that is subject to harsh working conditions and low pay in warehouses or Fulfillment Centers where staffers must urinate in water bottles in order to meet their quotas.

In his press conference following the launch, Bezos thanked that same workforce for helping him to shoot himself into space in a move that many critics have described as a simple “joyride.”

“I want to thank every Amazon employee and every Amazon customer because you guys paid for this,” he told the crowd, which responded with laughter. “Seriously, for every Amazon customer out there and every employee thank you from the bottom of my heart very much. It’s very appreciated.”

Critics on Twitter responded with derision, noting that Bezos was able to enjoy the trip at the expense of his hard-working employees.

“Thing is, employers are supposed to pay their employees, not the other way around, but that’s basically how Amazon works,” one user tweeted.

While another tweeter asked: “Maybe they’re searching space for signs of a livable wage or a way to pay their fair share of taxes?”

On Tuesday, Bezos blasted off in the sub-orbital New Shepard rocket from Texas. The date for the launch was chosen to coincide with the 52nd anniversary of the Apollo 11 moon landing.

Members of the crew, which included his brother mark and 82-year-old female astronaut Wally Funk, brought a number of historic items on the flight, including a piece of canvas from the conceptual plane originally flown by the Wright brothers, the goggles Amelia Earhart used to fly across the Atlantic, and a brass medal made from the first hot air balloon which flew in 1783.

Keanu Reeves Praised As Video of Him Offering Seat to Lady in Subway Resurfaces

Keanu Reeves is an actor who has long been loved by audiences —and not necessarily due to his acting skills, but due to how nice the John Wick star is.

And now, Reeves is once again earning praise as a “true gentleman” after resurfaced video footage shows Reeves giving up his seat on the subway.

The clip was shared by Instagram film fan account Cinemonkeys where it has since earned nearly 45,000 likes.

The video footage dates back to 2011, when it was shared on YouTube by a user of the video-sharing platform.

At the time, Reeves was already a superstar riding on the fame he earned from the Matrix, Speed, and a number of other blockbuster hits.

When Reeves notices a woman carrying a heavy bag, he quickly points to his seat and asks if she would like to sit. The woman accepts and Reeves gets up without hesitating to let her take his seat.

Reeves, ever the model citizen, then stands and holds onto a subway pole while carrying his bag.

The video has since been watched over 27 million times and was even cited in a 2019 Time magazine profile of the actor describing Reeves as the “soul mate” of the internet.

The resurfacing of the clip on Instagram once again impressed users of the platform.

“This human being’s soul honestly shines so bright,” wrote one user.

“OMG I love him in every single way,” another person commented.

His kindness knows no bounds,” commented someone else.

Keanu is set to reprise his role as Neo in the upcoming fourth Matrix film directed and written by Lana Wachowski, who co-directed the earlier trilogy with her sister Lilly. He will also return to the silver screen in John Wick: Chapter 4, which will be released in 2022.

Drunk Man Rescues Injured Baby Bird By Sending It To Animal Shelter… In An Uber

An injured baby bird received a new lease on life after a young man who was inebriated had the good sense to send the little creature to an animal shelter because he and his friends were too drunk to drive.

In the Summer of 2019, a small lesser goldfinch suddenly appeared by itself at the Wildlife Rehabilitation Center of Northern Utah. The center’s chairman, Buz Marthaler, was notified by a volunteer who sent him a photo.

“It was a picture of this bird, and it had come by Uber,” Marthaler told FOX13. “It was just crazy.”

As it turns out, the tiny bird – which was only two weeks old – indeed rolled up to the site by its lonesome, the sole passenger in an Uber vehicle called by concerned citizens who found the injured creature.

Among those good Samaritans was Tim Crowley, who had been “day drinking” on that Saturday before he and his buddies witnessed the little bird fall from the sky.

“Impromptu, sitting in some camp chairs, hanging out, having a few drinks when we had a visitor fall out of the sky,” he explained.

Crowley then snapped a photo of the bird and sent it to the WRCNU, which instructed him to immediately bring the bird in. However, the group obviously couldn’t drive since they had been guzzling booze all day.

So Crowley decided he’d hail a cab for the creature.

“At first it was a joke, like, ‘Hey, maybe we should just call Uber!’” he said. “Then we were like, ‘No, really. Why not? We’re paying them.’”

As it turns out, the bird – since named “Petey Uber” by staff at the rescue center – likely would have perished if not for Crowley’s quick thinking.

Marthaler remains impressed by Crowley’s move and shared the news on its Facebook page.

“While we feel we’ve seen it all and can’t be amazed by anything, there is always someone out there to prove us wrong,” the shelter’s post read. “Thank you to the rescuer who helped this little one get the care it needed in a timely manner and thank you for keeping yourself safe and others on the road safe as well.”
