Sixth sense! Study claims humans could develop 'bat-like' echolocation sensing abilities

A study, which appeared in Plos One earlier this month, claims humans have a very basic form of echolocation, a trait seen in other species such as bats and dolphins, that helps identify the shape and movement of objects through sound. Speaking to Pop Mech, Miwa Sumiya, Ph.D, a researcher affiliated with the Center for Information and Neural Networks and one of the study’s authors, said the finding may lead to greater understanding of the human brain.
Mr Miwa said: “Examining how humans can acquire new sensing abilities to recognize environments using sounds [i.e., echolocation] may lead to the understanding of the flexibility of human brains.

“We may also be able to gain insights into sensing strategies of other species [like bats] by comparing with knowledge gained in studies on human echolocation.”

Humans actually possess more than the five basic senses of touch, sight, sound, taste and smell.

In fact, humans have a variety of additional minor senses such as spatial orientation, proprioception (body position) and pain reception while other animals have even more advanced senses such as being able to detect electrical and magnetic signals.

In a complex experiment, 15 participants used a device to generate an echolocation signal that bounced off two oddly shaped cylinders which were either rotating or stationary and then listened back to the echoed sound through headphones.

The echoed sound was rendered binaurally to create a surround sound experience similar to that of autonomous sensory meridian response (ASMR).

Mr Sumiya added: “The synthetic echolocation signal used in this study included high-frequency signals up to 41 kHz that humans cannot listen to.”

Participants in the study were able to identify the existence of the rotating cylinders using only the echoed sound through timbre and pitch of the echo even though they could not directly see the objects.

Speaking to the Smithsonian Magazine in 2017, he said: “You could fill libraries with what we know about the human visual system, but what we know about human echolocation could barely fill a bookshelf.”

Sharks have a sixth sense for navigating the seas

The Earth’s magnetic field covers the entire planet like an invisible three-dimensional film. This all-encompassing force doesn’t drive human behavior (at least, as far as we know), but it’s an important factor in some animals’ ability to navigate—and that group has just expanded to include sharks, according to a new study in the journal Current Biology. The new research suggests that bonnethead sharks, just like certain species of migratory birds, sea turtles, eels, and others, use the Earth’s magnetic field to help them find their way. 

“We know that sharks, rays, and skates”—a group of fish known as ‘elasmobranchs’—“are sensitive to the electromagnetic field,” says lead author Bryan Keller, a PhD student in oceanography at Florida State University. But researchers hadn’t yet managed to demonstrate whether  they use that sensory ability for navigational purposes. 

“What we were specifically interested in testing, was if that ability allows them to infer map-like information from the Earth’s magnetic field,” says Keller.  

The team of researchers, funded in part by the Save Our Seas Foundation, a nonprofit that supports marine conservation research, looked at bonnethead sharks, a relatively small (and therefore lab-friendly) coastal species that had been shown to travel back to specific locations on a seasonal basis. The researchers captured 20 young bonnetheads in the Gulf of Mexico off the coast of Florida and brought them back to a lab, where they were placed in a tank inside a magnetic coil system that exposed the sharks to magnetic fields that resembled different geographic locations. They used software to track the sharks’ responses, observing which direction in the tank they were trying to swim towards.

“The main test we were interested in is exposing the shark to a magnetic field that represents the location far south of their preferred habitats where they spend their summers, up in the northern Gulf,” says Keller. For this test, they oriented the sharks about 600 kilometers (373 miles) south of where they were captured. Instead of swimming randomly or in circles around the edge of the tank, as they did in a control test that mimicked the magnetic field where they were captured, in this case the sharks swam in a kind of half-moon formation, moving leftwards and then rightwards in an apparent attempt to push north. 

In a test that looked at the opposite—whether they would try to move south if placed farther north than expected—the sharks did not demonstrate such a trend. The authors speculate that this could be because the sharks had no experience with this more northern magnetic field, suggesting that their “magnetic map” was something they learned to access through experience, rather than an innate ability they were born with. “But really, in order for us to make that claim, we need to do some more research,” says Keller. 

This study is “a big step forward in our general understanding of the navigation capabilities of these animals,” says Yannis Papastamatiou, an assistant professor of biology at Florida International University who was not involved in the research. “It’s not an experiment in the field,” he says, “but it’s still pretty convincing evidence.” Papastamatiou notes that researchers have used similar experimental techniques to show that turtles can navigate using magnetic fields.

The evidence here would have been even stronger if a second change resulted in a different direction, wrote Catherine Lohmann, a biologist at the University of North Carolina at Chapel Hill, in an email to Popular Science. “I would have liked to see the responses to a western location, for example.” 

The magnetic field might be especially useful for marine animals because they don’t have as much access to landmarks, stars or other guides, wrote Lohmann, who was not involved in the research. Overall, the research “adds to the larger idea that magnetic maps may actually be common in marine migrants.” 

And if they’re widespread in the sea, she suggested, “then they also may be widespread among animals in other kinds of habitats.”

Gogglebox Malone family's secret is out as fans see sixth sibling

Gogglebox’s Tom Malone Jnr has shared the happy news that he is going to be an uncle.

The former Channel Four star, who’s family have been on the show since 2014, shared a heartfelt photograph of his older sibling – who has not been seen on the show before.

The picture revealed his brother Lee got married and is expecting a baby to his 300,000+ followers.

The 26-year-old dancer wrote: “A massive congratulations to my older brother Lee Malone and his new wife Sarah Walker!!! Welcome to the family!!!

“And as a combo deal we don’t just get one new Malone…they’re expecting another one in November!!! Couldn’t be happier for you both!”

And fans couldn’t wait to send their well wishes, with one person writing: “Ahhh this is beautiful ! Congratulations guys”.

Another said: “Massive congratulations to all xxx”.

While a third added: “Awwww these are beautiful!!! Congratulations”.

Another confused follower questioned: “How many brothers and sisters have you got Tom? Losing track here, they’re popping up left right and centre!!”

Tom recently left the show announcing on Instagram he is 'back on the market' for TV work

To which professional dancer Tom replied: “There’s six of us”.

Tom previously appeared on Gogglebox with his parents Tom Sr and Julie and younger brother Shaun.

But Tom made an announcement earlier this year that he would be departing the show.

He wrote on his social media pages: “I’ve loved every minute and I’m eternally grateful to @channel4 and @studiolambert for allowing me to be a part of the show.

“But new opportunities are knocking on the door and it’s time to explore them.

“I look forward to enjoying the show as a viewer and not having to worry about having said something stupid.

“PS. Don’t worry my family @themalonesgb and @shaunmalone95 will still be on the show to keep you guys entertained every Friday. To the future.”

Grand National horse dies: The Long Mile put down in sixth death in last 10 years

A third said: “Sad for JP he wins the race but sadly the long mile is not coming home.”

A fourth wrote: “So sorry for The Long Mile and all connections at the stable.”

The Jockey Club has made several changes over the years to safety and welfare measures for riders and horses.

In the last decade, more than £2million has been spent on horse welfare measures on fences, landing areas and the ground at Aintree.

Both horses and jockeys are also required to meet stringent standards of fitness.

Every horse before the Grand National Festival also undergoes pre-race checks from a veterinarian to determine whether they are fit to race.

Races on the Grand National Course (three across the three-day Randox Grand National Festival) remain unique but fair challenges for horse and rider, but the evidence suggests, increasingly safer ones. Since 2012 there have only been two equine fatalities in the Randox Grand National from 318 runners.

Let's talk about six? Rival fans ridicule Liverpool as they slump to new low with SIXTH home loss in a row

Jurgen Klopp’s dreams of a second successive Premier League title have turned into a nightmare after his team suffered their SIXTH home defeat in a row after another Anfield slump, this time against relegation-threatened Fulham.

While some fans may have been wary of saying it out loud, there is now no doubt that the wheels have well and truly come off Klopp’s Liverpool juggernaut after the German’s injury-ravaged team dropped three more home points to Scott Parker’s side to mark their worst run of league form since the 1951-52 season.

A Mario Lemina strike towards the end of the first half was enough to seal a famous three points for the Londoners after the Gabonese international seized on a mistake from Mo Salah to squeeze the ball inside Alisson Becker’s right-hand post.

Liverpool made seven changes from the side which lost 1-0 at Anfield to Chelsea on Thursday with the likes of Diogo Jota, Naby Keita and Xherdan Shaqiri drafted into the side – but any hopes that an injection of new blood into the starting lineup may help eradicate their recent woes proved unfounded as the Reds appeared weary and listless throughout. 

And as you might have expected, fans on social media didn’t go easy on them.

Incredibly, Liverpool had gone 68 home league matches without defeat before beginning their run of defeats against Burnley in January. Since then they have emerged from games at Anfield with Brighton, Manchester City, Everton, Chelsea and now Fulham without a single point to show for their efforts.

This time a year ago, Liverpool went 22 points clear at the summit of the Premier League table after a home win against Bournemouth as they marched towards their first Premier League title in three decades – but just 12 months later, Liverpool’s form is among the worst in the English top division and they risk missing out on Champions League qualification altogether.

The negative statistics keep piling up, too. Liverpool have yet to score a home goal from open play this year while it is now fourth months since they kept a clean sheet at their previously impenetrable home ground. 

And in a season which promised so much, nowadays Liverpool must arrest the decline into mediocrity – after all, the last time this happened it was another 30 years before they won the league again.
