Alcalde Docs | For the Bees


– Every plant that has a flower that you can see depends on
insects to pollinate them, and the most important insects are bees. But there’s one species in particular that’s used in agriculture for pollination and that’s the honey bee,
the western honey bee. We really need honey bees. (gentle music) The winter of 2006 to 2007, so more than 10 years ago now, there was a huge die-off
in the U.S. of bee colonies and it wasn’t clear why. A consortium of people around
the U.S. got interested in determining whether there
was a new, a new disease agent, like a pathogen that
might have been introduced that was suddenly wiping out the bees, and we could use sequencing to try to figure out what it was. To make a long story short, there was no new, single new pathogen. That did not turn out to be the case, but by happenstance, we realized that, oh, there’s this set of bacteria
that live in every single bee. And we had samples from
before the colony collapse, from all over the world. So it turns out that many, many species, basically all animal
species, including insects, have bacteria that live in them or on them and that are sort of
part of their microbiome, but they hadn’t been studied
very much in the past. So they’ve been this kind of black box, we could use microscopy, we could see, oh yes, there’s some organisms there, but, couldn’t do anything else, they just knew they were there, basically, and people would speculate
about what they did. All kinds of things that
are going on, actually, maybe can be explained better once we look at this sort of hidden dimension that’s been hidden to
humans for all of history, no one’s ever been able to study it. So now suddenly, we have
the tools where we can, basically through molecular sequencing, understand what’s there,
and when it’s changing, and what genes are there,
and what they’re doing. And so suddenly, there’s this
whole kind of hidden part that really is completely undiscovered. We now know that it does a
lot of things for the bee, it helps it to digest food, it helps it protect against
pathogens and so on. So, we’ve been focused on that aspect, how does the microbiome enhance the health or affect the health of the host and that sort of opens up
sort of a broader arena of possible things that
could affect the bees, right? Because it’s not just things
that affect the bee directly and cause it to die,
like a poison to the bee. It’s something that might
disrupt the microbiome and then over time, the
bee is more susceptible or has poor nutrition and
dies at a greater rate. What we found, for example, is some chemicals that
disrupt the microbiome that might be used in agriculture. Even though that chemical
doesn’t immediately kill the bee and it’s not a toxin
directly, say, to the bee, it disrupts the microbiome, and then over a little
bit more extended period, that bee is susceptible to
a disease and then it dies. Some of the declines we see could be due to this kind of bigger web that, the microorganisms are
part of this big web that’s keeping everything going, we can’t see them, but
actually they’re important, and so when we do things
that disrupt those, that has these consequences. There’s these little
mites called Varroa mites and they are one of the worst
problems with bees right now. And beekeepers are grappling
with how to control them, and these mites feed on
the blood of the bee. A STAR graduate student
here, Sean Leonard, started some work and we
had the bacteria in culture, we could grow them, and he
started the very difficult work of developing genetic
tools for these organisms so that we could add genes to them and change their capabilities and then put them back in
bees and see what they can do. (gentle music) We put in a molecule that makes the mite attack its own self and die. We’ve shown that bees that have these modified symbionts
designed to target the mite, that the mites die at a higher rate when they’re on those bees. (gentle music) One possibility is that the things that are hurting the honey
bee, the honey bee hives, are actually affecting
insects more broadly. It’s just that honey bees are the ones that are basically domesticated, that we see when the hive dies. About the last three years or so, there’s a lot of evidence that
all insects are declining, which is extremely alarming
because it kind of means there’s big problems in
the ecosystem generally. Possibly, the declines in
honey bee colonies are kind of just one little echo of this broader thing that’s happening to insects generally. (gentle music) In my earlier life, I really
liked insects and plants, I mean, as a little kid, I was the one who liked all that stuff and I didn’t think of it
as an occupation at all, that was not anything anyone in my family did or anything close. I’m a member of a large family,
the third of eight children, and most of us went to
University of Texas. But I came here, took a class, and then I got to know
some graduate students and started doing research. Was working closely with
one graduate student and that got me interested
and I asked them where to apply to graduate
school and they gave me advice, and so I took whatever they
said and did it (laughs). There’s a lot of studies on bees, I mean, their behavior and how they
learn, how they navigate, and then, they’re actually
really important in the world. So I, basically, was already interested and then when this new colony collapse and there were these new
thing to study about them, I just decided, uh, this
is probably worth doing. A lot of things you can study, but people have done it for a long time, so you’re probably not gonna
find anything all that new because it’s been looked at by
smart people for a long time. So, I figure that’s
probably less promising than something that really
is unlooked at, so far. (gentle music)

Why do wasps build nests? | Natural History Museum


We have millions of wasp specimens here, and
amongst all the pinned insects we also have a more surprising collection, which is that
of about 1,000 or so wasp nests. These range in size from tiny little clay
pots to huge paper nests that fill people’s lofts. One of our most exciting examples of that
is this wasp nest. This is by the common wasp Vespula vulgaris. This made its nest in a bowler hat in an
outhouse on Sir Walter Rothschild’s estate. This is a fantastic example of how wasps
can be very opportunistic, making their nests anywhere which is safe,with
structural support.

Fleur & Bee | Rose and Shine – Refreshing Rose Water Toner


Hey lovelies, I’m Jenna. And I’m Caitlin. With Fleur & Bee. And we’re here to tell you about our refreshing Rose and Shine Natural Rose Water Toner. Oh. What? Well, I thought we were talking about rosé, so I brought some. Really? Well, let’s not let ’em go to waste. Absolutely not. Alright, so stick around everybody because at the end of the video, we might have a little surprise for you. Alright. Cheers. Cheers. So Jenna, what exactly is a toner and like what does it do? So, basically, a toner removes the excess oil and dirt from your skin and it also minimizes the pores on your skin, all while hydrating. Okay, so it sounds a little like a magical potion. Well, it’s not. Fleur & Bee does have a rose water toner and rose water is an antioxidant that has been used for centuries. And before people even knew what germs were, they would use rose water to wash their hands before eating. What… Okay, so if it’s cleansing your skin, how is it also hydrating your skin? Well, rose oil is a natural moisturizer, as well. So this is both? Yeah. And it also has soothing properties, so it can help to tone down any temporary redness as well. Okay, so what exactly is like in this toner? Rose water. No, I mean like I know, but what else is in it? Rose water. Okay, so it’s just like the one ingredient? Well, it’s actually, technically, two ingredients. Hey, see I knew. I knew there was like a catch or something. Yeah, yeah. So there’s two of them, not just one. So, it’s pretty simple. So the first ingredient is rose oil, and you get that from a steeped rose petals in water. And then the second one is distilled water. So basically any contaminants, minerals, heavy metals have all been removed, and this is the most pure form of water and so it has a neutral pH level. So basically, it’s just like rose water? Mm hmm. Okay. Alright, so who should be using a toner? Great question. So, everybody should be using a toner, but it’s especially good for people with very oily skin. It’s very helpful for them, as well as sensitive skin since it has those soothing properties. It’s great for those people as well. Alright. So is it a really intense spray? Does it feel like there’s a giant waterfall right there, just like very intensely spraying? No, it’s more of like a light mist. Okay. Yeah, if you’d like to try it, I have my Rose and Shine right here. Don’t mind if I do. Alright, just a little like… Yep, that’s perfect. Okay. That’s very nice. Yeah. It’s like a light little mist, as you said. And I’m getting the rose. You smelling that? It smells really nice. Oh. That’s super nice and very refreshing. Alright, so how often are you supposed to be using this? So you wanna be using it in the mornings and at night after you’ve already cleansed. But in reality, you can use it any time you want, like if you’ve been working out or if you feel like your skin feels more oily and dirty, you can use it throughout the day and any time you really want. Alright, and how long is it gonna last you? So, it depends on how often you use it, but if you’re using it twice a day everyday, it should last you about three to four months. Oh, okay. Now let me get this straight. This will cleanse my skin, it’s gonna hydrate my skin, it’ll soothe it, it’ll reduce temporary redness and then just overall refresh my face? Yeah, plus Fleur & Bee donates 1% to charity to help provide menstrual care and education to girls in need. That is amazing. Okay, so I feel like I need this in my life immediately. But it sounds like too good to be true. It’s gonna be expensive, it’s gonna be hard to get. You have to go on some type of quest to find it. So I don’t know, I feel like it’s too much. It’s actually really easy to find and super affordable. You just go to Fleur & Bee’s website, Fleurandbee.com, and it’s only $18. What? It’s only $18? $18, you heard me. Pardonne moi. Let me… Fleurandbee.com. Alright. Wait, what are you doing? I am ordering this right now. I’m just… I’m placing an order right this moment. Oh wait, don’t forget to use the code, YOUTUBE, for 25% off. Oh my goodness. Done. It’s already shipped. It’s already shipped. It’s shipped already. We have extremely fast shipping. We ship within one business day. What? Yeah, but Caitlin, you know you do work here and you kind of just picked it up here. Yeah, but this is more fun. Well, thank you guys so much for watching. And please subscribe to our channel for more fabulous beauty tips. And we’ll see you soon. Bye. Bye for now.

When Does Ant-Man and the Wasp Take Place?

When Does Ant-Man and the Wasp Take Place?


Ant-Man and the Wasp is the first film we
see that ties into the events of Infinity War, and while I previously assumed this movie
occurred concurrently to that one, new evidence suggests we’ve been at least partially mistaken. This is part 20 of a 20 part video series
discussing when each film in the MCU takes place. We’ll add future parts on to this series,
as more home releases are available for us to dig through. So when exactly does Ant-Man and the Wasp
take place? “URGH URAARLGHAOU… ULAAGH-AWHH!” “How’d you do that?” First things first, if we’re going to correctly
place this film, and in turn Infinity War, we need to take a line from that film to help
us with the timeline. “After the whole Accords situation he and
Scott took a deal. It was too tough on their families; they’re
on house arrest.” We determined that Captain America: Civil
War ended in early April 2016, in part 13 of this series. So how long has Scott been under House Arrest? “…Provided he serve 2 years under house
arrest, followed by 3 years of probation.” “Come on Woo, I’ve got 3 days left!” So directly after the signing of the Accords,
or after Civil War, Scott took a plea deal which put him under House Arrest for 2 years,
and considering he has 3 days left on house arrest, this should place this film in the
second week of April, 2018. And on that very day we see Scott attend an
online magic course where the date is none other than April 10th, 2018. Infinity War also firmly places itself in
2018, as we mentioned in part 19 of this series, and we also discuss that the main events in
that film occur over a 3 day period as well. Does that mean this occurs the same day that
Thanos’ Black Order attack New York? There’s no evidence of that being the case. In fact, while the main events of this film
occur within the last 3 days of his house arrest, he still cannot aid the Avengers for
3 years afterwards anyway, considering his probation period. So let’s backtrack a bit and try to explain
this further. We begin the film in 1987 (as we discussed
in part 12), and there’s also a pseudo-flashback we received shortly thereafter. We also get a brief glimpse back at 2015,
as we can see Hope’s hair appears as it does in Ant-Man. There’s also some time dedicated to flashback’s
for Ghost in some indeterminate year. On Day 1 of his remaining house arrest, we
see him going through his daily routine. On Day 2 he wakes up in Hope’s car, is introduced
to the Quantum Tunnel, meets Bill Foster, and finds Ghost later that night. The third day is the climax of the film, and
we know he is released from his house arrest period later that day. “Be back later for the official end of your
sentence.” A number of days pass after Scott is released
from house arrest and is now in his probation, so he still can’t communicate with the Avengers. He spent some time with his family, he spends
some time at work, Hank and Janet go on vacation, and Hope and Scott go on a date. A week, at least, must pass between the day
he’s released from house arrest and when Hope, Janet, and Hank get snapped at the end
of the film. The snap must occur on or after April 19th. To throw another wrench in the mix, we get
this date while Scott and Hope are on their date reading June 2nd 2017, which I’ll assume
is the date this shot was filmed, because this cannot take place in 2017. For what it’s worth, I’ll say that the
snap must occur between April 19th, 2018, and June 3rd. 2.7% of the film’s runtime
took place in 1987, 1.1% in 2015, 1.2% in some indeterminate year, and the majority,
95% took place in 2018. I sincerely hope you’ve enjoyed this series. It’s been a long time coming, and now that
it’s complete, I can finally get to work on piecing together the next version of the
MCU Chronological Timeline. Thank you so much for watching, and if you
haven’t watched each part, I highly recommend you watch this playlist right here, so you
can fully understand where all the films occur. Please like this video and subscribe for more
content just like it in the future. Thanks so much for your support. It truly makes me happy. Have a great day.

Evolution history of bees

Evolution history of bees


The genealogy of bees from 200 million years
ago to 5 million years ago. Dr. Poiner, an ancient creature researcher
at Oregon State University said that bee’s collect nectar and pollen and have a poisonous
stinger. These characteristics are related to the long
evolution of bees. Let’s talk about the history of bee evolution. The “bee” appeared on the planet more
than 200 million years ago, the same as the dinosaur. “The eggs were laid on the leaves and trunks
of the plants, and the larvae ate the plants. Sawfly and horntail. Later, bees spawning on insects appeared. New born larvae ate worms. Eventually, bees began to hunt insects that
fed on their larvae. Surprisingly, the oviduct evolved into a poisonous
stinger. Yes, the source of the poisonous stinger is
the ovipositor. So every bee that has a stinger is female. The same is true for honeybees. About 100 million years ago, when flowers
spread on the earth, bees using pollen as a food source appeared. Then, the flowers made nectar to attract bees
to get pollinated, and the nectar became the bee’s food. Thus, about 70 million years ago, the bumble
bee, the predecessor of modern bees, appeared. “This is a bumble bee fossil that has a
good feature of its time.” The hind legs evolved. The legs became thick and fine hairs developed
so that they could carry more pollen. Also, when the shapes of flowers changed,
the bees of those areas adopted, such as developing long tongues for sucking nectar. And about 5 million years ago, the bees that
live in our current swarms appeared. “Did you know that bees and flowers have
evolved together and have coexisted while adapting to the environment?” This is the long history of how bees evolved.
