Because it's #Pride2018, we wanted to explore two different sexual recognition systems in insects.

However, we also wanted to include some disclaimers.

1.) Mating behaviors in insects cannot, and should not, be applied to humans.
2.) These systems work very differently in bugs.
The sex lives of many insects are, well, to be frank...kind of horiffic.

@SciBugs said it best:

"Please don’t take dating advice from insects. Keep everything consensual in your love life."

Also, and perhaps this may not need to be stated outright, these posts will not be meant for children.

So...reader discretion advised.

For our last #DeepDive of 2018, let's talk about a mosquito that you'll be hearing a lot about in 2019.

Aedes aegypti is one of the most important disease vectors in the world.

So...what makes it a good vector, and why is it found worldwide?
Ae. aegypti is a mosquito that's originally from sub-Saharan Africa, adapted to living in the holes in trees.

This genus has a unique egg laying behavior. They lay their eggs on surfaces above water, and those eggs are dormant until the hole fills up.

In it's home range, there are two color forms.

One color form is dark, and doesn't hang out around people.

The second is lighter colored, and pretty much specifically feeds on people.

It's that second one which more or less took over the world.

This question, inspired by our cricket packaging thread, is another excellent question.

Even if we're not releasing mosquitoes, why do we need to breed them in captivity?

There's a few reasons...
The most important is a reference strain. Lots of mosquitoes were being bred in labs before pesticides were introduced, so we *know* they're not resistant to them.

If we're curious about a modern population, we can compare and use them as a standard.
Besides reference strains for pesticides, we know that the lab reference strains can transmit most of the 'normal' diseases that Ae. aegypti spread.

However, not all populations of Ae. aegypti spread every disease.

Why is that?

Scientists need to know!

In relation to that *amazing* cricket unboxing story comes this really awesome question.

How do you get 1,000 SUPER JUMPY crickets into a box in the first place?

Turns out, that's actually a surprisingly easy thing to do.

(Thread)
There is no shortage of videos/guides on how to rear crickets.

It's pretty easy, and you can generally get a few thousand in a rearing box at a time. Essentially, you rear->ship.

...but how do you move them from the rearing box to a shipping box?

It turns out that there are specialized tools for this.

One such tool, that you've probably seen in petstores is a cricket funnel.

This allows you to measure small amounts of crickets by volume, essentially you know roughly how many crickets are needed to reach a certain point.

It's actually not obvious to some why you shouldn't use a daily WEATHER map to say anything about climate change ...

This is with respect to @realDonaldTrump inane Tweet.

This goes for when the weather is warm or cold.
First, these daily weather maps are misleading because they not only mix two different weather model systems, but because they present the entire globe's temperatures compared to a local climatology or historical mean (2/n)
Good example of why this is misleading: in NYC today, the temperature was 30°F below normal for the morning low & daytime high.

That magnitude of anomaly just doesn't happen in the Equatorial Pacific tropics --> El Nino is triggered by about 1°F warm anomaly. Yes -- 1°F (3/n)

It's strange that everyone on health policy twitter is not going apes over the Hospital Outpatient Prospective Payment System (#OPPS) rule released today

It contains one hugely significant proposal that hospitals will fight bitterly...but could actually help them in the long run
Background- there are two different CMS payment systems for historic/operational reasons, one for professional services, and the other for hospital outpatient depts.

Up until now, there had never been an effort to make sure that equivalent services would have same payment rate.
In fact, the same procedure paid for in hospital OPD setting ended up being reimbursed at a much higher rate than the exact same procedure at a doctor’s office.

Here’s how @MartinSGaynor and Paul Ginsburg and I described it in our “Making Markets Work” White Paper

Comment vit-on la Pride en tant qu'intersexe : petit résumé de la journée #pride

👇👇👇👇👇
Pour rappel, une personne intersexe nait avec des caractéristiques sexuelles ambiguës sur le plan binaire mâle/femelle (génitales, chromosomiques, internes, externes, hormonales) et subit parfois dès la naissance des opérations et des traitements agressifs pour les "rectifier".
Nous sommes le I du cigle LBGTI. Notre condition est biologique avant tout, ms aussi identitaire et militante, car les intersexes dans leur majorité luttent pour leur droit à la dignité et à l'intégrité physique et morale. Nos luttes ont tout à fait leur place dans la comu LGBT+.

I'm gonna chat for a while about what it is like to be the B in LGBTQIA. Well most of the time it feels more the b in LbG(t). #pride #bisexuality
See binary concepts are a thing which are simple to understand, so for many people they struggle to get it when you say there is more then just straight or gay! J #pride
It's tough when your sexuality gets erased and derided, esp by those who are Gay and Lesbian. J #Pride

1. It's #Pride, so let's talk about the God and the LGBTQ community.
2. In Genesis, we read that God created humanity in God's own image. Scripture is clear: Each of us carry within us the divine spark, we are fearfully and wonderfully made, and God has pronounced this Creation "good."
3. From both science and folks' lived experience, we know that gender identity and sexual orientation are not incidental aspects of our being. They are not choices—they sit at the core of our humanity.

Things that surprised/amazed me about Japan, an ongoing thread.

(More likely UI than food, but you know this already.)

It’s my first time here. Please comment away and/or point out my cultural insensitivities!
1. A very friendly immigration officer and I laughed together, and when I said “I don’t really know where I’ll be staying,” he actually applauded it.
2. Very nice and clean train from the airport, with power sockets, and vending machines onboard.

Tons of solar panels passed by on the way.
