International student visa applications and approvals, Canada 2022-2025. We're down 90% on where we were three years ago. Given that intl student fees brought in about $14B at their peak, we're looking at the potential loss by 2028 of $12B of PSE income (or about 16% of the total).

Yesterday, 56 of our fab colleagues at the Physics & Astronomy dept in Nottingham, received “at risk of redundancy” letters. The Uni is planning to reduce the size of the Physics dept by almost a third.🧪⚛️🔭 Sign this petition to show them your support ✍️: nottinghamphysics.github.io/Open_Letter/
Petition statement

We, the undersigned, call on the University of Nottingham to reverse its plans to impose compulsory redundancies on its staff in the School of Physics and Astronomy.

The University threatens to cut twenty members of staff out of the seventy one currently in the School. On 12 May, fifty six of those members of staff received letters notifying them that they were at risk of redundancy. This affects academic and technical staff at all levels, from Research Fellows to Professors.

To the extent that Trump / Vance have a strategic vision for the US-UK relationship, it is not to strengthen the UK. The vision is to weaken Europe by severing UK from the continent. Trump-Vance true "special relationship" is with Russia. Russia desperately fears UK-EU unity 2/x

3/4. If we accept the idea that moving a person from one place to another undoes rights and disempowers the judiciary, we are endorsing the basic Nazism practice that enabled the killing of millions.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

The hope that universities nowadays are more than financial institutions with an attached educational/research department and that there might even be university leaders with some spine is, unfortunately, just not very realistic: www.nytimes.com/2025/04/14/o...

2025 Trump inauguration ceremony vs 2025 Breakthrough Prize ceremony www.youtube.com/watch?v=on5L... According to quantum mechanics, it is perfectly fine to put scientists on the pedestal and simultaneously also throw them under the bus.

Microsoft's extraordinary claim last month—to have created a bonafide topological qubit—was met with caution by many experts. Now, a physicist is raising specific and substantive concerns about a key test that underlies Microsoft's approach. My reporting: www.nature.com/articles/d41...

Ok. Once and for all. Trump is anti Ukraine, anti Democracy, anti Europe and, above all, pro Putin. There can be no more doubt—it’s just a disaster it’s taken so long for people to understand it.

When Russia invaded Ukraine, Finland’s then-president Niinistö said that the masks had fallen. If anyone was still clinging onto some kind of hope of Trump coming around on Ukraine, this disgrace of a press conference should make everything clear now. Trump is anti-Ukraine. Pro-Russia.

Good to see a detailed analysis but who really believed in stable topological regions after seeing these figures which looked nothing like one would expect theoretically?

The chaos and confusion of the Trump administration's science policy is taking its toll on early career researchers. Some prospective PhD students I spoke with have had informal offers rescinded as universities reduce or outright halt their programs. www.nature.com/articles/d41...

Nature hiding their reservations about the latest Microsoft paper in the review file: "The editorial team wishes to point out that the results in this manuscript do not represent evidence for the presence of Majorana zero modes in the reported devices." worked really well, see the NYT article:

Non-hermitian Hamiltonians are used to describe open quantum systems. As in Hermitian systems, topologically protected modes can exist. However, there has been considerable confusion about which modes are protected. We provide clarification in a recent paper in Phys. Rev. Lett. shorturl.at/jdegf

In 2016, we could console ourselves that however big a disaster Trump was, at least Canada could profit by offering an attractive landing spot for international S&T talent. We sure as hell aren’t saying that in 2024. Lack of science investment and a disastrous housing market have consequences.

Very concerned about the cap on international grad students. Research is international and Canada's competitiveness relies on student exchange and the influx of international talent. This is counterproductive.
