#Introduction Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.
One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy

Give #Musk the heave-ho: "It has been more than 150 years since a fellow has been expelled from the society, according to the spokesperson." He's earned it.

Shaken #Baby Syndrome Has Found New Life in Courts as Abusive Head Trauma. One Family Is Fighting Their Son’s Diagnosis.
—
Exonerations and new #science continue to raise questions about shaken baby syndrome, a diagnosis that lives on under a different name: “abusive head trauma.” Critics say the name deflects scrutiny while leaving #parents vulnerable to criminal charges.

📣 It's been a while since we've federated a batch of publishers — so to make up for it, here are 250, and they're big ones.
Today, we're bringing names like @abc, @RollingStone, @forbes, @BleacherReport, @NationalGeographic and @newyorktimes to the fediverse. They join the 174 profiles we've already federated, which include everyone from @19thnews to @Vox
Here's a blogpost with more details on this latest batch of publications that cover news, business, cooking, home design, politics, sports, science and more. Follow their Magazine feeds if you're only interested in one topic, or their whole profiles if you want the lot. The spreadsheet below lists out all federated accounts.

Astronomers have long thought that the upper clouds of Jupiter, which create the planet’s iconic pale brown belts, are made of frozen ammonia.
But the joint efforts between an amateur astronomer with his backyard telescope 🔭 and professional scientists with ESO's Very Large Telescope (VLT), have now shown that they're actually made of something completely different 😲
Most likely, they are made of ammonium hydrosulphide mixed with smog, although vertical convection can sometimes bring ammonia ice clouds to the top.

Hello people of mastodon! I’m here, I’m queer 🌈🦄 But I do prefer wine over beer! How about you? I don’t even know what this place is or does so I’m just screaming out into the aether! …or, well… the aether was debunked by scientists in like.. the 1920’s…but isn’t it kind of an expression people use? Or is that another aether? (I could be translating weird from Swedish too) I’ll have to research this now 😄

I've been reading up on the Lottery Ticket Hypothesis, which is super interesting.
Basically, the observation is that these days we build vast neural networks with billions of parameters, but most of the parameters aren't needed. That is, after training, you can just throw away 95% of the network (pruning), and it will still work fine.
The LTH paper is asking: could we start with a network just 5% of the size, and get comparable results? If so, that would be a huge performance win for Deep Learning.
What's interesting is that you can do this, but only by training the full network (perhaps several times) to see which neurons are needed. They argue that training a neural network isn't so much creating a model, as finding a lucky sub-network (a lottery ticket) from the randomly initialized network, a bit like a sculpter "finding" the bust hidden in a block of marble.
Initial LTH paper: http://arxiv.org/abs/1803.03635

This paper investigates how competition to publish first and thereby establish priority impacts the quality of scientific research. We begin by developing a model where scientists decide whether and how long to work on a given project. When deciding how long they should let their projects mature, scientists trade off the marginal benefit of higher quality research against the marginal risk of being preempted. Projects with the highest scientific potential are the most competitive because they induce the most entry. Therefore, the model predicts these projects are also the most rushed and lowest quality.
It's interesting to think about what subjects are perceived to be high value and therefore have rushed and low quality research regularly published about them. (attn @theluddite )

PRESS RELEASE: A research team led by Dr. Sofia Sheikh of the SETI Institute, in collaboration with the Characterizing Atmospheric Technosignatures project and the Penn State Extraterrestrial Intelligence Center, set out to answer a simple question: If an extraterrestrial civilization existed with technology similar to ours, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect, and from how far away? https://youtu.be/Pdg2x3NP2ds
What a $2 Million Per Dose Gene Therapy Reveals About Drug Pricing

Taxpayers and charities helped develop Zolgensma. Then it debuted at a record price, ushering in a new class of wildly expensive drugs. Its story upends the widely held conception that high prices reflect huge industry investments in innovation.
