Re:P-hacking
Like weather predictions of 30% chance of rain at 2 pm, did it actually rain 30% of the time?
That sort of research is done all the time. Usually it's on far more specific parts of weather models than the overall model. Weather models are ridiculously complicated, and scientists spend a lot of time on minor components of them like modeling aerosols better since they form the nuclei of clouds and thus rain, or the vertical humidity profile, or boundary layer dynamics. There are so many minor processes that make up weather that most of the research effort goes into things that 99.9% of the population never will even know even exist. In conjunction, all of these things will be what predict rain or temperature at a certain time.
However, once in awhile someone revisits the models as a whole, and you get something like this: http://www.inscc.utah.edu/~pu/...

Then eat different species
Right away I noticed this report talking about a decline in certain species yet generalized it to a risk for seafood dependent diets so I figured I should look to see which species are winning in the new environment.
According to this Science magazine article, the changing temperatures and increasing acidity of oceans is a boon for Octopus, squid, and cuttlefish.
https://www.sciencemag.org/new...While I believe wee may see increased prices and decreased consumption of certain species, I am certain other to-be-determined species will thrive in the changed environments as well, and that like Octopus, squid, and cuttlefish, we will find them both delicious and nutritious.

Re:Do these machines actually do anything useful?
It's been tested to work thousands of times better than traditional CPUs at simulated annealing operations; however, research leveraging DWave offerings have been slow to come out. You can reach an article where researchers used DWave technology to conduct their experiments. In addition, there are numerous published papers leveraging DWave tech including application in ML and optimization tasks (traffic).
But, healthy skepticism should setup a box around our confidence in any published research until it's verified--preferably on non-DWave systems, something which is pretty damn difficult today.

Re:easy to patent somethingFor the record: I'm a physicist doing research on superconductivity. My own work is on low-temperature superconductivity, but I've tried to keep up-to-date on high-temperature stuff.
Actually, they do. The electron-electron interaction of a Cooper pair has energies on the order of 10E-3 eV. The "high temperature superconductors" assume that somehow you can compensate the random heat movement (kT) and (also random) electric repulsion (order of eVs) by interactions in the crystal lattice.
This is a bit disingenuous. First of all, the critical temperature of a superconductor is proportional to the pairing energy, so trying to find a high-temperature superconductor is synonymous with increasing this energy scale. Having a pairing energy of ~1meV is typical for a good low-temperature superconductor (like Nb), where the pairing is caused by phonons. Compensating the random heat movement (~kT) would happen precisely by increasing the pairing energy proportionally. Note also that we don't really know how most high-temperature superconductors work (cuprates), but some theories actually invoke the electric repulsion you brought up as a possible mechanism for superconductivity.
Since the main question was whether high-temperature superconductors break any known laws of physics, you might also be interested to know that we already have near-room-temperature superconductors. After the discovery of superconductivity at 203K (-70C) in sulfur hydride (SH3) a couple of years ago, the record was recently pushed to 250K (-23C) in lanthanum hydride (LaH10). The caveat is that these materials require millions of atmospheres of pressure to function at these temperatures, so they're not that useful for practical applications. But they do demonstrate that room-temperature superconductivity is not prohibited by any physical laws; for instance, a high-pressure hydride would still be subject to the same thermal (~kT) and electron repulsion (~eV) conditions you referred to, but they still work. Secondly, if one is able to replicate the conditions inside these crystals chemically instead of via external pressure (e.g. via the "pressure" between atomic layers in a crystal), they could in principle be made more useful.
As for the article itself: I agree that it sounds unlikely. I'll believe it when I see a published paper replicating the effect, and eliminating other possible explanations of the observations. There are bogus papers claiming to discover high-temperature superconductivity all the time, such as this obvious fraud that made some headlines last year. -

Or maybe: tough courses cause poor grades
Here is the full article: STEM faculty who believe ability is fixed have larger racial achievement gaps and inspire less student motivation in their classes
Being a teacher, this kind of thing is important to me. And this article irritates me, because I think they get things exactly backwards. The article specifically examines the performance of two groups of students: white/asian vs. black/latino/native-american. The latter group is implicitly assumed to be disadvantaged by the fact that their average, group intelligence is lower than the first group. The hypothesis being that, if your teacher thinks you're less intelligent, you will do more poorly in class that you should.
Interestingly: the article states that there was no discernable grouping amongst the teachers. Teachers and their beliefs were evenly distributed across all ethnicities, genders, ages, etc.. So this isn't a claim of racism or genderism, but simply a claim that teachers with particular views are poorer teachers. This is measured by the fact that their students received poorer grades.
I think this is the critical flaw in the study: Those grades are assigned by the teachers themselves. There is no objective measure of student capability. Teachers with "tough" courses will, on average, give out lower grades. And lower still to the less capable students.
I teach introductory courses - filter courses - at my university. An essential part of my job is to fail students who are unlikely be unable to complete the course of study. Hence, I give lower grades than instructors in other courses later in the program, after the incapable students have been eliminated. I've been doing this a long time, and I have come to the view that students either have certain aptitudes, or they don't. I submit that I have come to this "fixed mindset" view by observation: teaching thousands of students, failing those who cannot develop the necessary skills, and passing those who can. My role as a teacher is precisely that: to help them develop skills. If they are incapable of doing so despite my best efforts? Then they are in the wrong program of study.
In other words, it's not a "fixed mindset" that causes an instructor to hand out poor grades, but the other way around: someone who teaches teaches tough courses will come to recognize that student aptitudes are largely inherent. There are exceptions: I've seen talented students fail through laziness, and marginal students get through with sheer grit and determination. Those exceptions, by their very rarity, serve to underscore the general pattern.
Finally, one must comment on the student evaluations. Students in courses that handed out better grades were more likely to have liked the course. That's not a surprise, that comes close to a law of nature. However, the study misses a great opportunity here. The authors admit that my theory (about tough courses being the root cause) might be true:
"It is possible that faculty who endorse fixed mindset beliefs create more demanding coursesâ"requiring students to spend more time studying and preparing for their course. If this is true, then differences in studentsâ(TM) performance and psychological experiences might be explained by the demands of these courses (instead of professorsâ(TM) mindset beliefs)."
One of the questions in student evaluations ("how much time did this course require?") would have been a good indication of course difficulty. Unfortunately, the study does not seem to have tested this hypothesis, or at least, the paper makes no mention of it. A cynic might wonder if they did do the analysis, but perhaps it didn't support the desired results. After all: "tough courses lead to lower grades" would hardly be a conclusion worthy of publication.

Correlations Should Be Published
I wish every weather service published a graph that showed the progress of the correlation between their 1 to 7 day forecasts and what actually happened, somewhat like the graph for hurricane tracks in the referenced article. Published confidence levels would also help to know how locked-in a prediction was.
My experience has been that forecasts a day or two ahead are amazingly accurate, but that you can't rely on forecasts a week out for scheduling an important event.

Re:This is exciting news
until you factor in the inevitable greed variable from the Pharmaceutical Cartel.
No surprise here, especially considering that this one is really a study by Cortexyme, Inc that is developing treatments for Alzheimer's and other degenerative disorders.
The list of authors and affiliations should be enough to give anyone pause: of the 13 authors the corresponding one (i.e., the one who got the study published) is Stephen S. Dominy from Cortexyme, Hatice Hasturk is affiliated with The Forsyth Institute "reinventing oral and overall health through pioneering biomedical research and transformational healthcare practices", and most of the others come from departments of oral immunology, dental medicine, periodontology, etc.
This alone should be enough to make anyone very suspicious but, in the event it isn't, the introduction clearly states:
"Infectious agents have been found in the brain and postulated to be involved with AD, but robust evidence of causation has not been established
[...]
P. gingivalis lipopolysaccharide has been detected in human AD brains, promoting the hypothesis that P. gingivalis infection of the brain plays a role in AD pathogenesis.
[...]
We developed and tested potent, selective, brain-penetrant, small-molecule gingipain inhibitors in vivo. Our results indicate that small-molecule inhibition of gingipains has the potential to be disease modifying in AD."So, according to the author(s) there is "no robust evidence" that P. gingivalis is really the cause of AD, but Cortexyme will be happy to sell you something that may (or may not) work. In other words, the article is just another press release in disguise.

Re:Remember, Remember, The 5th of NovemberThe Graph is the before, and the worse than we thought panic is from the error in the 2018 study. It didn't provide anything substantively new other than another method of calculating the same results as before, and the mag knows this. The Error made it look worse, and gave the study traction. But it was an error and has since had corrections issued.

Um, no. She's the second author in the paper so it's rather "the woman they interviewed since the the first author was a man."

Hint: post-doc programs are rather shorter than the stated 5 years - do more than 2 years in one place and you blow your chances to move up.

Physicists believe in negative mass....
because math allows it. But not everything is real what math allows. Just look at the epic failure of SUSY or read "Lost in Math: How Beauty Leads Physics Astray" from theoretical physicist Sabine Hossenfelder.
"However, studies have shown that the force driving the accelerating expansion of the universe is relentlessly constant."
And there are several studies which claim that the accelerating expansion of the Universe is an illusion. I think it would be simpler(?) to explain the galactic rotation problem and/or the Bullet Cluster without dark matter with a model. And if that model also says something about the expansion of the Universe which matches the observations that would be an extra. But no model should be built upon solely on the accelerating expansion of the Universe.
"It therefore appears that a simple minus sign may solve one of the longest standing problems in physics."
I have read a study which claimed that the bending of light around a galaxy was consistent with the velocity of the stars around the galaxy. That means space-time is really curved with the right amount since there cannot be any repulsive force which bends light.

Re: Who is submitter Chris Reeve
Re: "Dark matter is absolutely needed to explain the structure of the universe at the largest scales. Supercomputer simulations of the evolution of the visible universe only produce anything that resembles the large scale structure of the universe when using Lambda-CDM (i.e. cold dark matter) models. Those same models also produces the elements in the abundances we see today."
Notice that you completely ignored the fact that the jets we observe connected to AGN's exhibit this peculiar counter-rotation. These are cylinders of moving charge which contain yet more cylinders of charge moving in the opposite direction. How in the world are you going to explain concentric counter-rotating, counter-flowing electric currents with a gravitationally-driven source?
A 2014 Science article adds additional weight to that claim by noticing that the energy of the AGN jets appears to be around 10x the energy which the accretion disc could provide:
Plotting the luminosity of the accretion disks against the gamma ray power of their jets, the team reports online today in Nature that there is a clear linear relationship between the two. The brighter the disk, the more powerful the jets—cementing the idea that accretion disks and jets are linked. But in terms of total power being beamed out into space, Ghisellini says, most of the jets were producing 10 times that of their accretion disks. “There must be another engine, not just the gravitational energy [of accreting matter falling toward the black hole].”
So, is there a gravitational "black hole" driving each of these electromagnetic jets, or are the jets forming a network which then along certain points along the transmission line spin up galaxies?
That latter possibility is the question you refuse to ask even though the data is suggesting it.

First, I found QI interesting...
...not anymore. The problem with QI is that it is based on Unruh radiation. This Unruh radiation is supposed to replace dark matter and responsible for the peculiar velocities of stars in spiral galaxies.
Now, here's a problem:
A precise extragalactic test of General Relativity
http://science.sciencemag.org/...According to this study the rotational velocities of the stars are consistent with the bending of light around the galaxy. That means space-time is curved with the right amount which causes the velocities of the stars.
So, Unruh radiation cannot be responsible for these velocities since Unruh radiation is light and light cannot "bend" light. Actually, our current understanding is that nothing can "bend" light this way, only space-time curvature. This means there is something there which causes this "extra" space-time curvature (eg. dark matter).
I do not believe dark matter exists, but it won't be QI which solves these kind of problems.

Re:cement is amazing
I remember an article in Scientific American when I was a kid (decades ago) that described cement research. The one idea that stuck with me is that cement failure is precipitated by mechanical imperfections -- that much isn't so suprising -- which in cement are air bubbles. Remove the air bubbles and cement becomes as strong as aluminum, albeit considerably heavier. They demonstrated this remarkable property by making car springs out of void-free cement!
Yes, concrete is a fascinating substance. They've figured out what makes Roman opus caementicium concrete so strong http://www.sciencemag.org/news...
The secret was aluminum tobermorite, which is what was formed in situ by seawater dissolving the volcanic ash and forming the tobermorite, was what did the trick. Being a silicate also, these might just be sharing the same mechanism in this modern version of concrete?

More false scaremongering
You don't understand the science at all. Increases in CO2 alters the chemistry of plant growth...which means that they store a lot less nutrients.
You don't understand the amount that CO2 is actually affecting nutrients in the STUDY (singular, the one that all other scaremongering references).
If you actually look at the study the plants diminish in protein about 10%. That is not a LOT, and is more than made up for literally millions of acres of land that can grow more food.
Not to mention this study ONLY looks at rice, and even then qualifies that there need to be more strains of rice considered to say what even happens to rice!!! They aren't even willing to say that the study properly covers rice and you are extrapolating this result to every plant across the world.... now THAT is ignoring the science, and engaging in truly deep scaremongering.

Re:Don't confuse bleaching with dying
How much is normal? How often would you say this happens?
Severe coral reef bleaching is now ‘five times more frequent’ than 40 years ago, with climate change playing a significant role in the rise.
The longest-lasting recorded global bleaching event began in 2014 and continues to affect coral reefs worldwide. Few areas in the Southern Hemisphere escaped bleaching in the recently ended summer; surveys of the Great Barrier Reef suggest that more than 90 percent of it has been affected by bleaching.
Scientists first recorded a mass coral bleaching, one which affects entire reef systems and not just a few individual corals, in 1979. Sixty recorded events occurred between 1979 and 1990. Global coral bleaching events are mass bleaching across all three tropical ocean basins—the Atlantic, Pacific, and Indian Oceans. The first global event took place from 1997 to 1998, with at least 15 percent of global reefs dying, and the second occurred in 2010. Number three, still happening today, looks on track to be the worst ever, affecting 38 percent of the world’s reefs.

Crisper in EU
An EU court has already ruled that things made with CRISPR must follow the same guidelines as GMOs. Short form -- No GMOs in EU
Perhaps, since an EU member has money in the game, this will be reviewed

Maze of circular logic
“To classify gene-edited crops as GMOs and equivalent to transgenic crops is completely incorrect by any scientific definition,” said Nick Talbot, a molecular geneticist at the University of Exeter in the United Kingdom. “Precise modern gene-editing technologies allow accurate, predictable changes to be made in a genome.” http://www.sciencemag.org/news...
Translation:
"No, no, no, no. It's not a new number. It's--it's--it's just a changed number. See? It's not different. It's the same, just...changed."
Survey says:
"A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques (i.e., a genetically engineered organism)." https://en.wikipedia.org/wiki/...
The question was not about the precision of the modification. It was about it being modified. You've altered the genetic material, it means you've modified it! Hand back your degree. -

Re:...had been decimated with the arrival of Spani
Spare me your bullshit. The "peaceful" natives of the Americas were constructing literal towers of skulls, adults and infants alike. The Aztec Empire had been farming its neighbors for a century, by pushing them onto marginal land, then challenging the survivors to combat. The slaves they collected from these flower wars fed their cannibalistic cult of genocide.
There is no way to negotiate with a society like that. For the sake of humanity, it must be shattered and blown to the wind. Had they not wallowed in their technological slump, they would have brought forth a reign of terror that would have make Genghis Khan look like a hippie. Thank God that Cortez was able to destroy the Aztec Empire.
