Well, shit. I guess I should revoke my physics education card.

time to hit the AI books

Remember that star with the spikes of rapid onset and weirdly sustained dimming that was found in the Kepler data, KIC 8462852?

People started speculating about it being a partial Dyson structure and all that right away of course, various other explanations range from comet family collisions, polar spot growth, and so forth right?

Well... it's weirder than we thought, and has been dimming over the Kepler dataset, with a very rapid rate for that type of star (F3V) initially, then changing to a more rapid rate later, which is totally not what these stars are supposed to do. These results were found after analysis of photometric data over the last century or so suggested it has been dimming for a long time.

Wut?

didn't they discover that a good part of the historical dimming was due to the change in instruments in the last couple of centuries?

I wonder if we will ever know for sure what is happening up there.

How have I not heard of this...

If science always uncover earth-shattering revelations, then that would be pretty shitty science.

What a waste of effort.

Saying that relies on a basic misunderstanding of science and the process of a whole. Thinking that way is completely worthless for science in general, such an incredibly toxic way of thinking that it would be better not talking about science at all.

I'm not saying that's what you should do, only that you should stop thinking that way.

Negative results are exactly as important as positive ones. A negative result still brings forward understanding. Now we know quite specifically that the 750 GeV digamma excess is not the cause of a new particle--in fact, if I'm reading that right, it looks like it's a new interaction result for a very high energy proton pair interaction, which is also interesting.

As another example of a negative result being important: the Michelson-Morley experiment, to test what the speed of the Earth is relative to the luminiferous aether. We found the answer to be... not. The fact that this experiment was a catastrophic failure showed us that we had something wrong with our model and eventually helped bring along relativity.

On the other hand, the negative result at the LHC more shows us that our model is right, which is also a good result.

You may notice that anything that gets more data is a good result pretty much always. Even just redoing already-done experiments and getting the same result is important (in fact, it's one of the most important things in science--if an experiment isn't replicable, it's a worthless experiment, and the only way to test replicability is to replicate).

Screw wired and their popup crap: http://cds.cern.ch/record/2205245 there's the actual link which I got by deleting their adblock node and stopping all the extra loading from popping up before I could even find the linkthrough to the source.

From deep inside a Siberian mine, researchers have catalogued a series of materials unlike any others yet found in the ground. They do, however, bear a startling similarity to certain lab-grown materials that weren’t thought to exist in nature at all—until now.

Quote
In the last few decades, chemists have been crafting a series of new materials in their labs called metal-organic frameworks, or MOFs. These materials are “molecular sponges,” capable of soaking up gases like hydrogen or carbon dioxide—even storing them for future use, like a cell. A new paper in Science Advances reveals that not only are these materials also found in nature, we’ve had them in our hands for over 70 years. We just didn’t know what they were.

To get things slightly back on topic, interesting new camera from NASA actually allows filming of details in the exhaust plume of a rocket. I'll be the first to admit this is more clever engineering than SCIENCE!, but it will no doubt be useful in the future.
