Study sheds light on how birds breathe better

Published

on

Washington [US], March 20 (ANI): Researchers at the New York University have discovered that birds breathe with greater efficiency than humans due to the structure of their lungs looped airways that facilitate air flows that go in one direction.
The findings appeared in the journal Physical Review Letters.
The study, conducted by researchers at New York University and the New Jersey Institute of Technology, also points to smarter ways to pump fluids and control flows in applications such as respiratory ventilators.
“Unlike the air flows deep in the branches of our lungs, which oscillate back and forth as we breathe in and out, the flow moves in a single direction in bird lungs even as they inhale and exhale,” explains Leif Ristroph, an associate professor at NYU’s Courant Institute of Mathematical Sciences and the senior author of the paper.
“This allows them to perform the most difficult and energetically costly activity of any animal: they can fly, and they can do so across whole oceans and entire continents and at elevations as high as Mount Everest, where the oxygen is extremely thin.”
“The key is that bird lungs are made of looped airways — not just the branches and tree-like structure of our lungs — and we found that this leads to one-way or directed flows around the loops,” adds Ristroph. “This wind ventilates even the deep recesses of the lungs and brings in fresh air.”
The one-way flow of air in birds’ breathing systems was discovered a century ago. But what had remained a mystery was an explanation of the aerodynamics behind this efficient breathing system.
To explore this, the researchers conducted a series of experiments that mimicked birds’ breathing in NYU’s Applied Mathematics Lab.
For the experiments, they built piping filled with water — to replicate air flow — and bent the piping to imitate the loop-like structure of birds’ lungs — similar to the way freeways are connected by on-ramps and off-ramps. The researchers mixed microparticles into the water, which allowed them to track the direction of the water flow.
These experiments showed that back-and-forth motions generated by breathing were transformed into one-way flows around the loops.
“This is in essence what happens inside lungs, but now we could actually see and measure — and thus understand — what was going on,” explains Ristroph, director of the Applied Mathematics Lab. “The way this plays out is that the network has loops and thus junctions, which are a bit like ‘forks in the road’ where the flows have a choice about which route to take.”
The scientists then used computer simulations to reproduce the experimental results and better understand the mechanisms.
“Inertia tends to cause the flows to keep going straight rather than turn down a side street, which gets obstructed by a vortex,” explains NJIT assistant professor and co-author Anand Oza. “This ends up leading to one-way flows and circulation around loops because of how the junctions are hooked up in the network.”
Ristroph points to several potential engineering uses for these findings.
“Directing, controlling, and pumping fluids is a very common goal in many applications, from healthcare to chemical processing to the fuel, lubricant, and coolant systems in all sorts of machinery,” he observes. “In all these cases, we need to pump fluids in specific directions for specific purposes, and now we’ve learned from birds an entirely new way to accomplish this that we hope can be used in our technologies.”
The paper’s other authors were Steve Childress, a professor emeritus at the Courant Institute and co-director of the Applied Mathematics Lab; Quynh Nguyen, an NYU physics graduate student; Joanna Abouezzi and Guanhua Sun, NYU undergraduates at the time of the research; and Christina Frederick, an assistant professor at NJIT.

I ABSOLUTELY LOVED THE PROCESS: RADHIKA APTE ON HER DIRECTORIAL DEBUT

Published

on

Mumbai: Actress Radhika Apte has donned many hats while portraying different roles for her films and now she has taken up direction too. The actress released her directorial debut ‘The Sleepwalkers’ trailer in the lockdown at Palms Spring International Short Fest which won ‘The Best Midnight Short’ award.

Making her directorial debut with the short-film titled The Sleepwalkers, the actress in a recent interview with a leading publication shared, “I had never thought of making films. There was no such plan. I just had the urge to write because sometimes you want to create content that challenges you. Roles that come your way are not necessarily from the space that you want them to come from. I just wanted to write something that interested me. There are things that I passionately want to do. When I bounced off the story to Honey Trehan and Abhishek Chaubey, they decided to make it. I had 10 days for the prep and shoot. When I finished writing, I realised I didn’t want to act in it, but I wanted to direct it. And, I absolutely loved the process.”

Fans of the actress cannot wait to witness the magic Radhika has created, this time being behind the lens. The trailer of her short-film has been showered with lot of appreciation from the audiences.

 Her performance in the recently released OK Computer was widely appreciated and she will be next seen in ‘Mrs Undercover’ playing the role of a housewife who turns Undercover agent.

Los Angeles: American singer-actor Lady Gaga recently shared an emotional message with fans after her 2013 album ‘Artpop’ returned to the Top 10 chart on iTunes.According to Fox News, in a Change.org petition, over 40,000 fans signed an online document demanding that Interscope Records release the B-side of the ‘Artpop’ album, also called ‘Act II’ after DJ White Shadow, a producer on the album, teased she has a number of unreleased songs. Fans said they wanted to “show the Haus of Gaga that we still care about the experimental album and that chart success does not matter.”The Grammy-winning singer reacted to her album’s newfound popularity with a sweet message on Twitter.“The petition to #buyARTPOPoniTunes for a volume II has inspired such a tremendous warmth in my heart. Making this album was like heart surgery, I was desperate, in pain, and poured my heart into electronic music that slammed harder than any drug I could find,” she wrote.“I fell apart after I released this album. Thank you for celebrating something that once felt like destruction. We always believed it was ahead of its time. Years later turns out, sometimes, artists know. And so do little monsters. Paws up,” wrote Gaga.Per Fox News, when the album originally dropped, it received mixed reviews like The New York Times saying it pumped “so insistently it sometimes forgets to breathe.”Gaga also included R. Kelly in the song ‘Do What U Want’ but has since removed him and apologised for working with an alleged sexual abuser.“I’m sorry, both for my poor judgment when I was young, and for not speaking out sooner,” she said in 2019 via Twitter.
