There is no way some other lazy person hasn't done the same thing I did.

I can't stand these popular science articles that just cherry pick phrases from a paper. tl;dr it's a very promising result but more observation of other galaxies or other mass consistent observations is needed before we should believe this.

However, the signal from the MW halo alone does not constitute the definitive proof of dark matter annihilation. Detection of annihilation signals from other objects or regions with consistent WIMP parameters will be crucial for the final confirmation. Gamma-ray observations of dwarf galaxies in the MW halo are fascinating from this perspective.

I would say the most exciting part is this gives us a mass range to optimise the search with earth based detectors. Start looking for 0.5-0.8 TeV masses.

I mean what's the hypothetical other option here? We increase the background rate in a city of 10 million people to say, 200 mSv/year for five decades and do the experiment to see if their genetics can handel it to get statically meaningful data? For all we know right now it could be fine, or thousands of people get cancer that otherwise would not have, no one has the data to know. It's a pretty unethical study.

Even if you removed all safety requirements from the nuclear industry (never going to happen) it will still be expensive, there is too much infrastructure, too many systems, control loops and moving parts. The reality is solar just wins in cost and it is probably only going to keep making headway over the rest of the generation tech out there. Given the development rate of batteries I expect solar/batteries will become the power generation standard simply though economic drivers more than anything else. I doubt it's possible to beat that gravity contained fusion, and if we ever get cheaper superconducting links, then it's basically game over for everything else.

But we will always have reactors. We need the medical isotopes, and let's be real, they will keep breeder reactors for bomb fuel.

Dear Staff and Students

I am writing today to notify you that Distinguished Professor Genevieve Bell is tendering her resignation from her role as Vice-Chancellor and President of the Australian National University.

Distinguished Professor Bell will be undertaking a period of leave, and will return to the ANU School of Cybernetics in due course.

On behalf of the ANU Council, I thank Distinguished Professor Bell for her service as Vice-Chancellor and President of our University.

Distinguished Professor Bell’s statement is below.

Kind regards

Julie Bishop

Chancellor

Hi everyone,

I am officially tendering my resignation as Vice Chancellor of the Australian National University, which will be accepted by the Chancellor and Council.

This was not an easy decision.

As many of you know, the ANU has been a special place for me, ever since I was a child. And being its 13th Vice Chancellor has been an extraordinary privilege and also a heavy responsibility.

Like the rest of our community, I believe firmly in our delivering on our national mission – to create and transmit knowledge through research and teaching of the highest quality. And know that doing this requires a solid financial, cultural and operational foundation.

Achieving such a foundation has been difficult and this has been a very hard time for our community. I am grateful for all the ways that people have shown up and for all the work that has been done and the progress we have made.

Like the rest of our community, I know there is still more work to do so. I very much want to see the ANU thrive into the future and for it to continue to be a remarkable place and I don’t want to stand in the way of that.

So I am stepping down from my role as Vice Chancellor. My plan is to take time off, including a period of study leave, and then return to the School of Cybernetics as a Distinguished Professor where I hope to continue to contribute to our community.

Distinguished Professor Genevieve Bell

Replacing the Australian National University vice chancellor is a necessary first step to rebuilding the reputation of the ANU and restoring its legitimacy.

That an investigation will be led into the corporate governance, leadership and culture at the Australian National University is a broader signal about how we govern our public institutions and why that matters for every Australian.

Given the scrutiny on ANU leadership, there will be many, and probably a vast majority, of university staff who would be relieved to see it result in the end of ANU vice chancellor Genevieve Bell’s leadership of the institution. Regardless of whether they think she was the right person for the job when she started, everyone hoped that her time at the top would be successful.

However, walking around Acton Campus this week, it’s nearly impossible to find anyone who thought the last two years had been a success.

But that relief should not slide into joy, let alone triumphalism.

First, there is a very human story caught up in the chaos. Even those most opposed to the VC’s decisions must recognise that she has a deep affinity for the ANU. To reach the very top of one’s professional career, and then face scrutiny in a job you have coveted less than two years into a five-year term, must be devastating.

No more devastating than being told you are being made involuntarily redundant – as many ANU staff have – as part of a change-management plan, of course. But devastating nonetheless.

The second and more important reason to keep the champagne on ice is that a change in leadership does not guarantee a change in policy.

Replacing the ANU vice chancellor is a necessary first step to rebuilding the reputation of the ANU and restoring its legitimacy. But it is not a sufficient step. If there is a change of leadership, there has to be a change in where the ANU is being led to.

“The first and most immediate change in direction should be to rescind all involuntary redundancies.”

There is much about the stated principles of Renew ANU that the university community can get behind. A public institution like the ANU does need to manage taxpayer money and student fees as efficiently as possible. One of the principles of Renew ANU is:

“The academic strategy and operating model must support research priorities, teaching excellence, and financial viability. Resources, funding, and workforce planning will be data-driven to align with student demand, research funding, and strategic priorities”.

We have veered so far from that principle that listing it on any ANU document at the moment is disingenuous at best. More accurately, it is pure gaslighting.

A principle like this wouldn’t lead to massive cuts in student recruitment and support, nor would it threaten the jobs of highly cited researchers or popular academics. It wouldn’t trim areas that generate millions for universities through public policy work, or lead to the arbitrary disestablishment of long-standing institutions.

Most importantly, an institution that respected its staff and its students would see involuntary redundancies as the absolute last resort, not the easy option. If we can’t tell future academic superstars that a continuing position actually means something, why would they come here and commit their professional life to the ANU?

A change in leadership creates an opportunity. But that opportunity only means something if it leads to a genuine change in direction. There is a change that needs to happen immediately, over the next year or two, and in the much longer term.

The first and most immediate change in direction should be to rescind all involuntary redundancies. Not just a pause, but a recognition that the premises and data used to support the vast majority of targeted redundancies were flawed. It will take time to build back the trust and confidence of those staff who have been targeted and the areas in which they work. But the time to start is now.

The medium-term change in direction is to rebuild the university for the second quarter of the 21st century, but to do it properly. What would that look like?

It would involve a genuine, compelling vision for what we want the ANU to be – including the sources of revenue that will get us there.

The ANU should be completely open about its finances. This includes being clear and transparent about how budgets are set for colleges, schools and portfolios, and then adjusting those formulas where needed – and believe me, they are needed.

Governance reform

It would involve setting up good data and good systems before firing good people. And using in-house expertise in the first instance, rather than expensive consultants.

If, having done that, a restructure of colleges or schools or portfolios is needed, then a strong and compelling case should be made. If there are underperforming staff and areas, then performance manage. But don’t do it under the cover of change management, such language no longer convinces staff and students.

We need to start again on our journey to financial stability, but do it properly this time.

The third and most important genuine change needed, though, is governance reform. Bad governance is what got the ANU into this mess. Good governance in the long term is going to be what gets us out. Pressure for this is coming from government, as it should.

But ANU and ANU Council need not wait for that. Corporate governance principles are important reference points for a large organisation like the ANU. But they are neither sufficient nor fit for purpose. The ANU’s role is to serve the public good through world-class research, teaching and policy engagement. Financial stability is important, but it is not an end in and of itself.

A university is not a corporation with lecture theatres and labs – it is a public trust.

There are several clear directions ANU governance should be taking, and that can be undertaken without waiting for government to intervene.

They include increasing the representation of student and staff elected representatives in decision-making, strengthening democratic accountability of council members and the executive, bringing executive pay into line with community standards, greater openness and transparency with council meetings and decision-making, and frequent independent audits of governance processes and outcomes.

Ultimately, why is it that the vice chancellor’s leadership is facing pressure? Is it because of a few poorly worded emails and a domineering manner in meetings? If that’s the only reason, then it is a pretty flimsy basis, and a change in leader is unlikely to impact on the staff and students that much.

Or is it because she presided over a poorly designed, poorly delivered and poorly communicated set of change proposals that had real, demonstrable negative impacts on staff and student morale and wellbeing, and tanked the ANU’s reputation and standing among the community and its academic peers?

If it is the latter, then a change in leadership has to coincide with a change in direction, and a change in structure.

If governance and policy direction doesn’t change, it won’t matter who sits in the vice chancellor’s chair – the outcomes for staff, students and the public will be the same.

This article has some huge issues.

As mentioned already, the type of gun matters a lot. No mention of how many are semi auto, but I am guessing it won't be many.

Also no accounting for population growth over the last 30 years as a factor in total gun numbers.

This paragraph was absolutely journalistic garbage.

"NSW firearm registry data shows that in Sydney there are more than 70 individuals who own more than 100 firearms, including one person who owns 385 guns. The register notes that this is not a collector or a dealer."

Clearly this is a hobby/interest and the person is a collector with too much time and money (good for them I guess). What they don't have is a "collectors" licence that effectively means they cannot ever use their guns. A licenced collector will usually have inoperable firearms on display (think museum).

All that said, the SSAA and others do have a higher than normal concentration of right wing nuts that continuously lobby the government to weaken our excellent (imo) gun laws. It's why I stopped giving them any of my money.

I'm with the RBA on this one. The price on the sticker should be what I pay no matter the format I pay in. It's one of the great things about aus.

Cash still has significant overhead and businesses manage to account for that. Digital should be no different.

I installed fedora to replace windows on the 31/12/2023. I wasn't a complete Linux noob by any measure but haven't run it as a main OS before. Thank you proton for getting me over the edge.

The whole repo situation on fedora is honestly pretty meh, things are out of date or broken too often. Or they just don't exist. I have put arch on a number of machines since and find it significantly better. My main box will move away from fedora next time I'm enthused to mess with it and this is the primary reason.

How can we reduce paracetamol poisoning? Better access to mental health services? Nah. Let's make them buy two boxes instead of one. That will do it.

What a joke.

Depends if you care about names or about physics. Radio, Infrared Gamma etc are just names we give to various parts of the continuous electromagnetic spectrum. The edges of these definitions are not super well defined. Changing from RF to microwave could be defined at say about 3 GHz, but there is not some clear physical difference between a 2.9 GHz photon and a 3.1 GHz photon other than the frequency change.

The lower limit to the frequency is I guess the inverse of the theoretical age of the universe/2. Something can't currently be oscillating slower than that.

There are some theories on plank length, quantisation limits, etc that might set some theoretical upper limit of photon frequency. But we don't appear to be anywhere close to observing such things. We have seen some rather crazy short wavelength particles that we haven't fully understood.

Wikipedia is amazing, and I have donated to them a number of times. But something just rubs me the wrong way about their current donation drive and anything I read about how much their higher ups are getting paid makes no sense to me. Why are the salaries so high? Where is the clear breakdown of server cost and infrastructure?

Even when in power and offering cash incentives, the LNP couldn't convince the power industry to extend coal power plant lifetimes or build new generators. Renewables have already won the free market, they will likely never be beaten in our lifetime. Good fucking luck getting any company that wants to actually make money to invest in nuclear.

The only reasonable argument left for nuclear is the baseline and storage argument, but again the writing is on the wall, industry can see the trajectory that batteries and storage tech is on and know that by the time they spend 2 decades investing in current gen nuclear, it will probably be beaten by storage in the free market anyway.
