The ice-cube observatory in Antarctica reveals the source of high energy cosmic neutrinos. Spoiler: its Blazars!

Hate spoliers!

Machine learning yields detection of 72 new fast radio bursts from distant galaxy. SETI folks are getting excited.

There goes your moon base...

Travelling through wormholes is not much different from quantum teleportation using entangled black holes...

Finally some Internet for our meeting room!

First really strong evidence that the vestibular system affects sleep architecture, sleep stability and sleep spindles. If there is an effect due to a changing acceleration there might also be an effect of no gravity vector. We'll find out when I get the space shuttle data.

Starship and the Super Heavy:P made of steel. Well, maybe makes sense.... read the article

An alternative to photon-beam driven sails?

Interesting pictures taken by NASA's Juno spacecraft.

Works for mercury as well.

uups :)

Well, I wouldn't expect a reply: "all our past emails have been downloaded and sold to NASA" even if that was the case.

Of course Marek is right... What matters is the theatre of security, not security itself. Just like in airports :)

The party is over.

This literally terrifies me

It may be feasible to use this in the Marsian atmosphere (9mbar CO2) to directly grow Carbon Nanofibres for infrastructural needs

nice!

gave it to Hanna, she is looking into it now. Manchester and Ghent University could be potential collaborators.

I'm afraid I take some issue with this rather glorious title. I've only skimmed this paper but looking at the experimental details, their 'imagined universes' comprise of a ball confined in a 2D space as well as a double pendulum. Work along this area is nothing new - it's known in the control community as Inverse Reinforcement Learning - learning dynamics of some system from demonstration trajectories. The paper title ('Toward an AI Physicist for Unsupervised Learning') is more moderate so yet again the issue is how AI is reported in the media...

We should apply this also for space habitats

Yeah, put everything in a computer and let it think about it.

Two ways of measuring the universe's expansion rate yield two conflicting answers. Many point to the possibility of new physics at work, but a new analysis argues that unseen errors could be to blame. See also this work based on GAIA data that, on the other hand, reinforces the discrepancy: Milky Way Cepheid Standards for Measuring Cosmic Distances and Application to Gaia DR2: Implications for the Hubble Constant https://arxiv.org/abs/1804.10655

The quest for finding Planet Nine is meant to stay apparently.
