NPR’s Juana Summers talks with Regina Barber and Viet Le of Brief Wave about parrots dunking meals in water, an enormous gap within the solar and the lifeforms uncared for by emoji makers.
JUANA SUMMERS, HOST:
It is time now for our common science information roundup with our buddies at NPR Brief Wave podcast, Regina Barber and Viet Le. Hello, all.
REGINA BARBER, BYLINE: Hey.
VIET LE, BYLINE: Hello.
SUMMERS: So how this works is you might have introduced us three science tales that caught your consideration this week. So what are they?
LE: How a couple of examine concerning the lack of biodiversity in emojis?
SUMMERS: OK. However I’ve to inform you I do love a superb penguin emoji.
BARBER: I imply, I really like the penguins, too.
LE: Me too.
BARBER: And we even have a narrative a couple of group of fancy parrots that realized to dunk their meals earlier than they eat it.
LE: And a gap within the solar that is the size of 60 Earths.
SUMMERS: OK, OK. Pause, please.
BARBER: (Laughter).
SUMMERS: There’s a big gap on the solar? What’s going on right here?
LE: Yeah. So that is fairly massive. Like we stated, it is longer than 60 Earths. Nevertheless it’s humorous, you’ll be able to’t see it along with your bare eye.
SUMMERS: You shouldn’t do this. Please don’t have a look at the solar.
BARBER: Do not have a look at the solar.
LE: Proper. Appropriate. Do not – please do not. And even with a particular photo voltaic telescope or these photo voltaic glasses individuals put on throughout a photo voltaic eclipse, you really would not see this gap.
BARBER: Yeah, as a result of this coronal gap – that is the technical title – is seen within the excessive ultraviolet and a few X-ray elements of the sunshine spectrum.
LE: And that a part of the sunshine spectrum, it exhibits up as an enormous darkish space.
SUMMERS: OK. That is type of scaring me, however you each appear actually calm. Is that this regular?
(LAUGHTER)
BARBER: Yeah. I imply, these coronal holes do occur, like, a good quantity. They usually can generally trigger issues for us due to how they work together with photo voltaic winds. So photo voltaic winds are made up of magnetic fields and charged particles that come off the solar’s corona. And photo voltaic winds are being continually emitted from the solar. They usually’re much less contained at these coronal holes as a result of these coronal holes are much less dense and the magnetic discipline is, like, weaker there.
LE: So within the space of those coronal holes, the place the magnetic discipline is weaker, the photo voltaic winds can escape at a lot increased speeds. These winds can provide Earth its stunning auroras however may also disrupt satellite tv for pc communications if they’re intense.
SUMMERS: Interrupt satellites – y’all, I’m involved once more. Please assist.
BARBER: Effectively, do not be anxious about this one. This one’s not going to do very a lot. I talked to Lisa Upton about this. She’s a photo voltaic physicist at Southwest Analysis Institute. And he or she says that for those who type of relate the photo voltaic wind to type of rain on Earth, then this gap simply makes that rain a little bit bit extra intense.
LISA UPTON: It is extra like, you already know, a heavier downpour of rain than, as an example, a hurricane, a coronal mass ejection the place you are sending a variety of mass and particles on the Earth.
LE: Additionally, the solar is being continually monitored by an orbiting photo voltaic observatory simply in case there’s something that will be really worrisome. And for these on the market who wish to have a look at this gap, try the web site for NASA’s Photo voltaic Dynamics Observatory.
BARBER: So, like, all in all, that is, like, a flashy headline that perhaps some individuals have seen, nevertheless it would not actually have an effect on your on a regular basis life.
SUMMERS: OK. That’s good to know. So this subsequent story, it is about parrots who wish to dunk their meals earlier than they eat it?
BARBER: Proper. So we’re speaking particularly about Goffin’s cockatoos. They’re these white-colored parrots. And within the wild, you’ll find them in locations like Indonesia and Singapore. However the ones on this examine reside in an aviary on the Messerli Analysis Institute in Austria.
LE: Yeah. I spoke with Jeroen Zewald, a co-author on this new paper within the journal Biology Letters. And he says at some point within the lab, they noticed a cockatoo take its meals – principally rusk, which is that this actually laborious, dry toast – and dunk it within the water earlier than consuming it – one thing they hadn’t seen earlier than.
JEROEN ZEWALD: We noticed it in a single particular person and we’re like, huh. That is fascinating. Is that this unintentional or – properly, let’s control it. And, like, not even 5 minutes later, we noticed one other one doing it as properly.
BARBER: After which a 3rd. So that they determined to begin watching the birds for this, like, food-dunking habits. And by the top of the remark interval, seven of the 18 had dunked.
SUMMERS: So I take it then that meals dunking is uncommon in birds?
BARBER: Effectively, really, meals dunking has been noticed in different chicken species. You probably have a pet parrot at residence, you really could have seen them dunk their meals. However we additionally do not actually know why these cockatoos are doing it. So that is what the examine was, partly, making an attempt to determine.
SUMMERS: Effectively, I haven’t got a pet chicken at residence, however I do know that there are some individuals on the market who wish to dunk their chocolate chip cookies in milk as a result of they suppose it is tastier. I do not agree, however OK. Do cockatoos do that as a result of they suppose it is yummier?
LE: Sadly, they dominated that out as a result of the cockatoos are utilizing contemporary water to dunk, so it actually would not have an effect on the style. Our researchers imagine the extra seemingly purpose – and that is perhaps not a complete shock – dunking softens the meals. However Zewald says they’re nonetheless unsure if it is to enhance the feel of the meals, to assist them digest it, or perhaps each.
BARBER: Nonetheless, he says, that is an thrilling outcome as a result of solely a number of the cockatoos did this, and we’ve not seen this habits on this species within the wild. The researchers write they imagine this meals dunking is a spontaneous foraging innovation by a number of of their cockatoos.
SUMMERS: These sound like some good birds. OK. Lastly, our final subject – the shortage of biodiversity in our emojis.
LE: Sure. Juana, I am unsure for those who’re an enormous emoji consumer.
SUMMERS: Effectively, my group chat actually is.
BARBER: (Laughter).
LE: Effectively, subsequent time you suppose to make use of an emoji, take an in depth have a look at your animal and nature emoji choices as a result of a workforce of conservation biologists from Italy did simply that, and so they discovered that emoji are unrepresentative of the particular biodiversity that exists in nature. So, as an example, a variety of cat and canine emojis. For fungi, although – and there are a variety of species of fungus on the market on this planet – you might have one emoji.
SUMMERS: Unhappy face emoji. How’d they determine this out?
BARBER: Yeah. So this was written all up in a examine that got here out this week within the journal iScience. And the researchers went to Emojipedia, an emoji reference web site, and categorized all of the emojis which are associated to nature and animals. They usually recognized issues like 92 animals, 16 crops and one fungus.
LE: And whenever you examine these numbers to the proportion of species scientists have really recognized, they discovered that whereas animals are properly represented within the emoji catalog, crops, fungi and microorganisms have been underrepresented.
SUMMERS: So what I am listening to is one mushroom emoji is, maybe, not sufficient.
BARBER: Effectively, in accordance with these researchers, it is not sufficient. And taking a look at simply the animal emojis, about 75% represented vertebrates – so animals with backbones. A a lot smaller proportion of those animal emojis have been arthropods, which embrace bugs and crustaceans.
LE: However in the actual world, the precise proportions are the opposite manner round. There are over 1,000,000 recognized species of arthropod, whereas recognized species of vertebrate are someplace within the tens of hundreds.
SUMMERS: OK. All jokes apart right here…
BARBER: (Laughter).
SUMMERS: …Does it actually matter if I solely have one fungus emoji to textual content all my buddies?
BARBER: Effectively, I imply, this examine argues {that a} extra consultant set of nature and animal emojis might be a robust instrument for elevating consciousness and speaking about biodiversity, particularly for those who’re making an attempt to succeed in numerous audiences.
LE: Though I, and maybe others, could also be a little bit overwhelmed by all of that and simply stick with my thumbs up and smiley face emojis.
SUMMERS: And me, I’ll stick to my penguins.
(LAUGHTER)
SUMMERS: Regina, Viet, thanks a lot.
BARBER: Thanks, Juana.
LE: Thanks.
SUMMERS: That’s Regina Barber and Viet Le from NPR’s science podcast Brief Wave, the place you’ll be able to study new discoveries, on a regular basis mysteries and the science behind the headlines.
