If that is only published in PeNAS there is a 30% chance it is fake. Garbage journal as Academy members can submit articles with no peer review. It should be prestigious but some of the papers in there....... We were banned from bring PeNAS articles to journal club in grad school
.All that being said this is likely true and is pretty damn cool.
This is a direct submission though, meaning that it's not coming from a member, if I understand their process correctly. Anyway, it's weird what you're saying, cause isn't PNAS also one of the world's highest ranked journals?If that is only published in PeNAS there is a 30% chance it is fake.

If it's a direct submission it "should" be fine. I think that the guidelines have changed over the years but it used to be that Academy members would submit their friends papers with little to no review. There was some real garbage in those days.
Ha! That's weird. Sounds like 19th century stuff...
But even if the paper were garbage, the fact that water is really a very weird liquid remains a cool factoid. Or rather, 66 cool factoids of weirdness, although I don't think I've ever seen a full list.

Where my nuclear fusion enthusiasts at?
How long until the "I've made a practical nuclear fusion reactor in my garage" videos start to appear?
Couple of years ago there was this Italian guy who basically claimed something like that. From how much we heard about him since, I reckon it didn't go too well.How long until the "I've made a practical nuclear fusion reactor in my garage" videos start to appear?
Energy is one of our most severe constraints though, so fusion would solve a whole host of problems. Would really be a leap
Is it actually a major breakthrough though? Just seems like the normal incremental steps we've been seeing for years. It's not a massive leap from China's attempt a couple of months ago is it?
Happy to be educated as to why it's significantly different.
It's double the last test in 1997 I think. It's only enough to boil 60 kettles but it's endless energy. They're already building a bigger reactor in France so it just vindicates that endeavour and it's another step towards potentially limitless 'free' energy. I put free in brackets because, you know, Capitalism.
The fusion announcement is great news but sadly it won't help in our battle to lessen the effects of climate change.
There's huge uncertainty about when fusion power will be ready for commercialisation. One estimate suggests maybe 20 years. Then fusion would need to scale up, which would mean a delay of perhaps another few decades.
And here's the problem: the need for carbon-free energy is urgent - and the government has pledged that all electricity in the UK must be zero emissions by 2035. That means nuclear, renewables and energy storage.
In the words of my colleague Jon Amos: "Fusion is not a solution to get us to 2050 net zero. This is a solution to power society in the second half of this century."
How many years is it away this time, less than 50?
I realise it's controversial to some people, but I think the big error a lot of countries have made in the last 30 years is not going for more fission reactors to tide us over. It's carbon free, efficient and the western european reactors have been safe. The waste is an issue but over a 40 or 50 year period where it can act as something to use before we potentially gets fusion that it is a no-brainer compared to carrying on with coal, gas etc.
Apart from that any progress in this area is good new - I love how the comparison is with boiling kettles of water. How much more English does it get?
This test wasn't endless energy though as it was still more energy in to the process than energy gained right? Just an extension of output
I don't think we'll see that for another decade at any real non-miniscule scale.
Just seems like another small step, the US and China are making these all the time and after each one the press go wild. Interesting for sure but a distraction from real issues.
I live only about 5 miles from ITER, and I bet this news has made those folks super happy! It seems so weird having a giant experimental fusion reactor in the middle of sleepy Provence.
Nuclear Fission is far from being carbon free. Just take a look at the absolutely massive construction site ongoing at Hinckley in Somerset.
None of that construction is carbon free. The amount of cement being used alone is huge.
Ok. Focusing purely on the Fission electricity generation does not produce carbon.
But all of the associated processes will generate some CO2 outputs.
All of these experiments are yet another small step forward.
This JET experiment was limited to 5 seconds because that was the maximum amount of time that they could run at the incredibly high temperature without cooling.
It was more proof of concept in that the choice of Deuterium/Tritium works.
I am more optimistic that most that a functional Fusion reactor could be operational within a couple of decades.
Of course, but that's not really any different from any other form of large scale power generation builds and we would be in a far better position in reducing Co2 if we had more nuclear and less carbon based electricity now. Renewables are the ideal for the moment of course, but replacing carbon sources with fission would have had a big impact. Fusion will have the same problem in Co2 generation when constructing.
Agreed. And please don't think that I am against nuclear energy because I am very much in favour. Especially Fusion.
Fission is the only option in the short term.
But I believe that the new Rolls-Royce small reactors are going to be significantly lower in terms of construction carbon release.
I always wondered about whether this could be true. When my grandmother died she started randomly talking about distant memories from her life in the minutes before she went, like she knew it was coming.

Can’t remember where I heard this, could have been an article or the musings of a moron but I heard it described as the brain searching desperately for a memory or solution to keep itself going and stop it from shutting down, in the knowledge that it’s about to be curtains. Similar in any near death experience like drowning or an actual natural death.

Pretty cool but I see Seinfeld type problems already: How about sex?
It's been the obvious next step for a while, I'm hoping it'll develop fast from here. If anyone hasn't tried the Live Transcribe app on the phone, give it a go, it's already impressive - not perfect but excellent for a free app. People have developed versions of it with directional microphones so the user can tune in more readily to an individual speaker at a meeting or an event. Obviously it works better with some speakers, speech rates, accents etc than others.
We've also seen subtitle boards and individual subtitle glasses in use at some live theatres for a while - but they were pretty clunky:

It's a great demonstration of where the technology is heading. Personally I'm looking forward to the live Transcribe and translate version for foreign languages.
That's really cool. We're going to be able to do so much better for people with disabilities on so many fronts.

That thing is going to haunt my dreams!
So many horror film creators are being inspired right now!
But it's also really cool.
This reminds me of The Blob.

Hell yah, this is some cool shit. Back in my grad school days they were just starting some of this but the computing power just wasn't there. I still think there is going to be a need for crystallization to confirm, especially for pharmacological uses, but this was always coming. Beyond that tere are so many proteins of unknown or hypothesized function that can be analyzed in silico now. Hell, the protein I studdied is still of unknown function (well I think I know what it does, but it had no homology with any other bacterial protein of similar function so PI buried it).This is really cool stuff for the life siences:

If I remember correctly from a few months(?) ago, they're already using this to come up with new proteins, and AlphaFold2 immediately came up with some really interesting stuff with good potential.
...if I'm not completely mixing things up now.
I'm a grumpy old scientist so I care less about novel proteins (unless you are talking about biological therapeutics, then we can have a discussion!) and more about building a better understanding of ourselves and nature.

). My real interest would lie in the ability to model bacterial membrane protein complexes to be able to tailor new classes of antibiotics. Understanding the 3D structure of transmembrane proteins is really difficult.Yeah, I think I mistook that. It doesn't really just 'find' new proteines and know what cool things they could do.I'm a grumpy old scientist so I care less about novel proteins (unless you are talking about biological therapeutics, then we can have a discussion!) and more about building a better understanding of ourselves and nature.
