"A trio of British scientists working in US universities have been awarded this year's Nobel prize"
Sums up the state of UK science funding, Hammond get your wallet out.
A trio of British scientists working in US universities have been awarded this year's Nobel prize for physics. The prize will be shared by David Thouless (82), Duncan Haldane (65) and Michael Kosterlitz (76) for their work on exotic states of matter. The men will share the 8 million Swedish kronor (£720,000) prize. Thouless …
The UK brain drain sounds much like what goes on in Oz. The politicians talk about science this and smart economy that, but it's far easier to earn way too much money just being a drill monkey or nailgun maniac. The mining boom has left a legacy of thick shits that got paid far too well and an poorly funded education sector where too many people now think the streets are paved with gold as long as they wear a fluoro jacket.
Thouless moved to the US in the fifties to do his doctorate with the (German, somewhat Jewish) renowned nuclear physicist Hans Bethe.
The attractiveness of a venue for your research career is mostly determined by the environment: secure post, non-invasive bureaucracy, company of accomplished scientists you can hope to learn from.
Resources for research and a non-insulting salary are something but they are relatively unimportant. The UK is on a relatively good footing at the moment because the US has joined it in a race to the bottom in terms of a managerialistic ("work-like") culture.
"Haldane discovered how topological concepts can be used to understand the properties ..."
No mere mortals have a hope of understanding it! But whatever it is it's probably brilliant ... :-)
Meanwhile, if anyone finds one, I appear to have lost the inside of my Klein bottle ...

Purely as an observation, Cambridge UK occasionally mentions how many Nobel laureates they have and a fair proportion of those were born abroad, so if the US wants to claim these three then the UK can hardly object.
It probably ought to be credited to the institution(s) that supported them when they did most of the work.
I did read somewhere that a possible approach to HTSC beyond 163K in cuprates is to replace the copper with magnesium, as the resonating valence bond theory suggests that the heavy metal oxide-oxide-metal- layering structure is more important than the elements in it.
As Mg is *almost* identical to copper in many ways substituting Mg into YBCO copper sites could also superconduct and this has indeed been documented, with Sr substituting for Ba also giving a boost to Tc.
The critical temperature seems to be a factor of periodic compression so the actual upper limit for cuprates may be as high as 270K.
Trump fits the standard psychological profile with many symptoms common to: a mild bipolar person with delusions of grandeur, pathological liar, illogical (uses many of Aristotle's 144 fallacies) bully syndrome, self-centered egotistic but with low self-esteem, denial of culpability, the deflector of truth, the perfector of diverting blame, the master of half-truths, the pretender of great self-integrity ( no drink and smoke is not enough) and the mistaken leader who doesn't care what others think as long as he gets his way or else you will be a victim of his revenge. but with strong opinions and never loses an argument due to his exceptionally talented/ignorant use of fallacy. He has built a political empire capability of withstanding any attack from seemingly irrational actions but are very rational from a point of view of person who will put himself above every law. Already he has thwarted Nepotism, Money Laundering in his vast empire of Trump Towers, taunting Russians to tamper Hillary's e-mail
... not to mention that morality and ethics are voids in his clean-cut yet fake blonde and orange personal image.
Engineers at the University of Pennsylvania say they've developed a photonic deep neural network processor capable of analyzing billions of images every second with high accuracy using the power of light.
It might sound like science fiction or some optical engineer's fever dream, but that's exactly what researchers at the American university's School of Engineering and Applied Sciences claim to have done in an article published in the journal Nature earlier this month.
The standalone light-driven chip – this isn't another PCIe accelerator or coprocessor – handles data by simulating brain neurons that have been trained to recognize specific patterns. This is useful for a variety of applications including object detection, facial recognition, and audio transcription to name just a few.
Video Robot boffins have revealed they've created a half-millimeter wide remote-controlled walking robot that resembles a crab, and hope it will one day perform tasks in tiny crevices.
In a paper published in the journal Science Robotics , the boffins said they had in mind applications like minimally invasive surgery or manipulation of cells or tissue in biological research.
With a round tick-like body and 10 protruding legs, the smaller-than-a-flea robot crab can bend, twist, crawl, walk, turn and even jump. The machines can move at an average speed of half their body length per second - a huge challenge at such a small scale, said the boffins.
Updated Intel and QuTech claim to have created the first silicon qubits for quantum logic gates to be made using the same manufacturing facilities that Intel employs to mass produce its processor chips.
The demonstration is described by the pair as a crucial step towards scaling to the thousands of qubits that are required for practical quantum computation.
According to Intel, its engineers working with scientists from QuTech have successfully created the first silicon qubits at scale at Intel's D1 manufacturing factory in Hillsboro, Oregon, using a 300mm wafer similar to those the company uses to mass produce processor chips.
The largest academic supercomputer in the world has a busy year ahead of it, with researchers from 45 institutions across 22 states being awarded time for its coming operational run.
Frontera, which resides at the University of Texas at Austin's Texas Advanced Computing Center (TACC), said it has allocated time for 58 experiments through its Large Resource Allocation Committee (LRAC), which handles the largest proposals. To qualify for an LRAC grant, proposals must be able to justify effective use of a minimum of 250,000 node hours and show that they wouldn't be able to do the research otherwise.
Two additional grant types are available for smaller projects as well, but LRAC projects utilize the majority of Frontera's nodes: An estimated 83% of Frontera's 2022-23 workload will be LRAC projects.
Researchers at the Paul Scherrer Institute and ETH Zurich in Switzerland have managed to accomplish a technological breakthrough that could lead to new forms of low-energy supercomputing.
It's based around something called artificial spin ice: think of water molecules freezing into a crystalline lattice of ice, and then replace the water with nanoscale magnets. The key to building a good spin ice is getting the magnetic particles so small that they can only be polarized, or "spun," by dropping them below a certain temperature.
When those magnets are frozen, they align into a lattice shape, just like water ice, but with the added potential of being rearranged into a near infinity of magnetic combinations. Here the use cases begin to emerge, and a couple breakthroughs from this experiment could move us in the right direction.
British outfit First Light Fusion claims it has achieved nuclear fusion with an approach that could provide cheap, clean power.
Rather than rely on expensive lasers, complicated optical gear, and magnetic fields, as some fusion reactor designs do, First Light's equipment instead shoots a tungsten projectile out of a gas-powered gun at a target dropped into a chamber.
We're told that, in a fully working reactor, this high-speed projectile will hit the moving target, which contains a small deuterium fuel capsule that implodes in the impact. This rapid implosion causes the fuel's atoms to fuse, which releases a pulse of energy.
US scientists have succeeded in demonstrating self-heating plasma in a crucial step towards self-sustaining fusion energy.
Researchers at National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California have published a peer-reviewed paper describing how they achieved burning plasma — where the heat from fusing nuclei take over as the main source of fuel heating — across four experiments which each produced more than 100 kilojoules of energy.
The result marks an important milestone towards the promised land of nuclear fusion, but is only one step toward true ignition – where a self-sustaining reaction will produce more energy than goes in. Even then, engineering challenges of efficiency, scale and reliability remain on the road ahead.
Research published today confirms that what scientists thought were two types of active galactic nuclei are, in fact, one: the features were simply tilted at different angles.
UK minister for science and research George Freeman has admitted that vital EU funding for research is in limbo while the nation continues to negotiate Brexit sticking points, namely Northern Ireland and fishing rights.
Speaking to Parliament's Science and Technology Committee late last week, Department for Business, Energy & Industrial Strategy minister George Freeman said the geopolitics of Anglo-European relations – in particular Anglo-French relations – around fishing and the Northern Ireland Protocol were complicating the decision over "association" with the European Commission's €95bn Horizon research programme.
"I think it's pretty clear that we're in a holding pattern, with our association not being granted," he told the committee.
The European Space Agency's Solar Orbiter followed up its whizz past Earth as 2021 drew to a close by passing through the tail of a comet. Again.
While eyes were turned to French Guiana and the impending launch of the James Webb Space Telescope, for a few days around 17 December the spacecraft flew through the tail of Comet C/2021 A1 Leonard.
It's not the first time; the spacecraft also passed through the tail of the fragmenting comet C/2019 Y4 ATLAS in May and June 2020, a few short months after its launch.
