Disappearance Of Biological Sex In Research ‘Is Like Stalin-Era Purge’
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Sir Anthony Finkelstein, a university vice-chancellor, laments that the category has become ‘politically uncomfortable’
These three paragraphs add detail to the post.
A university vice-chancellor has warned of the “quiet disappearance” of sex as a recorded variable in academic research, likening pressure to abandon politically sensitive classifications to Stalin-era persecution of statisticians.
According to Times Higher Education, Sir Anthony Finkelstein, head of City St George’s, University of London, made the remarks at an event to discuss the Sullivan review, which recommended that biological sex be used as the default category in research data collection.
Finkelstein said it was essential that researchers retain established classifications for sex in their statistical analysis. He said: “In recent years, there’s been growing unease about recording sex as a basic variable, and pressure — sometimes explicit and sometimes ambient — to replace it with or collapse it into gender identity.”
I fund and participate in medical research and certainly wouldn’t do so, if I felt the research was not being conducted in a scientifically-correct manner.
Trump May Have Alzheimer’s, Says Niece
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Mary Trump said the president appeared to have developed a ‘deer-in-the-headlights look’ that reminded her of his late father, Fred Trump.
These three paragraphs add detail to the story.
President Trump’s niece has suggested her uncle could be suffering from Alzheimer’s based on a “deer-in-the-headlights” expression that reminds her of the president’s father.
Mary Trump, a longtime critic of her uncle, said she saw flashes in him of Fred Trump, her grandfather, who she witnessed struggle with the degenerative disease before his death aged 93 in 1999.
“Sometimes it does not seem like he’s oriented to time and place,” Mary Trump, 60, told New York Magazine of her uncle. “And on occasion, I do see that deer-in-the-headlights look.”
Fifteen years ago, my consultant at Addenbrooke’s said I should go on Warfarin (rat poison) to thin my blood. But my GP said I should stick to a small aspirin every day.
The result was that I had a serious stroke on holiday in Hong Kong.
Luckily, I made a remarkable recovery and I am now testing a Warfarin replacement drug, which is two pills a day and no testing, except by the doctors every three months.
My current cardiologist has even used the GP’s actions in a lecture to students on how not to behave.
Trump is playing with fire!
Surely he should at least be taking Warfarin and being tested frequently.
If any cardiologists are reading this, they should note, that I am coeliac and for the last twenty-eight years, I have been having regular B12 injections.
As B12 injections are used in Trumpland to help stroke patients recover, but not in the UK, from observations of my own recovery, by several doctors, I am tempted to believe that B12 injections may help stroke recovery.
Any sensible offer to help in research will be considered.
From my own experience, an affordable drug, like B12 injections could have a place in stroke recovery.
To get a second opinion, I asked Google AI, this question. – “Do Vitamin B12 Injections Help With Stroke Recovery?”
I received this answer.
Vitamin B12 injections may aid stroke recovery, particularly for individuals with a deficiency, by supporting nerve function, reducing homocysteine levels, and enhancing neurological rehabilitation. Research indicates that adequate B12 levels are crucial for protecting the brain after an ischemic stroke.Key findings regarding Vitamin B12 and stroke recovery:
- Neuroprotection: Vitamin B12 aids in maintaining myelin sheaths, which are essential for nerve repair and protecting the central nervous system after a stroke.
- Reduced Damage: Studies suggest that B12 can help reduce cerebral injury and improve long-term neurobehavioral function.
- Correcting Deficiency: People with B12 deficiencies often have worse stroke outcomes, making correction via injections crucial.
- Homocysteine Control: B12 helps lower homocysteine, a risk factor for vascular damage and recurrent stroke.
- Efficiency of Injection: For those with absorption issues (e.g., older adults or those with GI issues), injections bypass the digestive system to ensure maximum absorption.
The NHS will face a lot of resistance, if they want to take away my B12 injections.
Do B12 Injections Help Stroke Recovery?
A friend, who thinks I’ve made a good recovery from a stroke, asked me if there is anything I could recommend, for another of his friends, who has just had a stroke.
As a coeliac, am I in a group with a higher risk of a stroke?
So, I asked Google AI, the question, if this were true and received this answer.
- Initial Higher Risk: Some studies suggest a slightly increased risk of stroke (roughly a 10-15% increased likelihood). This risk is highest in the first year after diagnosis.
- Effect of Gluten-Free Diet: After 5 years on a strict, gluten-free diet, the risk of stroke for people with coeliac disease is virtually the same as that of the general population.
- Overall Risk: While some studies have suggested a link, others, including a 2023 UK Biobank study, found no clear evidence of an association between coeliac disease and stroke, although they did find an overall increased risk of cardiovascular disease (27% higher).
- Mechanism: The potential for a higher risk is likely due to the chronic inflammation associated with untreated coeliac disease, rather than traditional risk factors like high blood pressure or smoking.
- Children: A 2023 study found that coeliac disease plays a minimal role in the risk of stroke in children, but recommended that doctors consider it a potential factor in cases of stroke with unknown causes.
Conclusion:
While untreated coeliac disease may slightly increase the risk of stroke due to chronic inflammation, adhering to a gluten-free diet helps manage this risk.
This study by coeliacUK and Oxford University, was the source of the findings by Google AI.
Do B12 Injections Help Stroke Recovery?
For nearly thirty years, ever since I was diagnosed as coeliac, I have had regular three-monthly B12 injections. So ever since my stroke in 2011, I have had B12 injections.
So now AI is available, I felt I should ask Google AI to see if it says anything useful.
This is the answer I received.
- Nerve Repair & Axonal Growth: B12 aids in repairing damaged nerve fibers (axons) and regenerating nerve cells, vital for restoring lost function after a stroke.
- Reduces Inflammation: It helps calm the harmful inflammatory response (neuroinflammation) in the brain after an ischemic stroke, notes this ScienceDirect article.
- Improves Brain Communication: B12 supports neurotransmitter production, allowing brain cells to communicate more effectively and speeding up healing, according to this Flint Rehab article.
- Lowers Stroke Risk: By reducing homocysteine levels, an amino acid linked to stroke, B12 can help prevent recurrent strokes, reports this Flint Rehab article and this NIH article.
- Supports Microglia Function: It helps functionalize microglia (brain immune cells) to reduce injury and promote recovery, states this ScienceDirect article.
- To Boost Recovery: For those with moderate deficiencies, injections or supplementation can improve neurological function, notes this NIH article.
Conclusion
B12 injections seem to have done me no harm.
I also have them on the NHS, at no cost to myself.
If the NHS said I couldn’t have them, I’d pay for them.
Electric Freight: A Solution To The WCML Capacity Conundrum
The title of this post is the same as that of this article on Rail Engineer.
These two paragraphs introduce the article.
Network Rail considers the West Coast Main Line (WCML) to be the busiest mixed traffic railway in Europe. It carries 125mph passenger trains from London to the West Midlands, North West, and Scotland and is used by 90% of intermodal UK rail freight which has a maximum speed of 75mph. Traffic on the line has been steadily increasing. In 1994 there were seven daily passenger trains from Glasgow to London. Now there are 26.
In 2006 Network Rail commissioned an in-depth study to find the best way of providing additional capacity as, with increasing traffic, the WCML between London and the North West was forecast to be full by 2020. The study found that the provision of a new high-speed line was the best solution and was the basis for the development of the HS2 project. The 2006 study correctly forecast that the WCML will by now be at full capacity south of Crewe, yet following the curtailment of HS2 two years ago there are no proposals to address the capacity issue between Rugby and Crewe that was identified 20 years ago.
David Shirres, puts forward a solution that involves electric freight locomotives and faster freight wagons.
I can add some knowledge of what British Rail were doing in the 1970s to solve the problem of freight on the West Coast Main Line all those years ago.
This picture shows a PACE 231R.
In the early 1970s, I was lucky enough to work with one of these amazing machines. They were probably one of the most powerful analogue computers ever built, that could solve a hundred simultaneous differential equations at once using thermionic valve circuitry. Their most famous application was at NASA, where two of these machines formed the analogue half of the moon-landing simulator.
There were a handful of these powerful beasts in the UK at ICI Plastics, where I worked, British Motor Corporation, Cambridge University and British Rail Research at Derby.
At the time, British Rail were trying to run freight trains faster and the four-wheel freight wagons of the time were derailing with an unwanted regularity. So the problem was given to British Rail Research and the problem was put on the PACE 231R. The problem was solved and the lessons learned were applied to the Mark 3 Coach and the InterCity 125.
After privatisation, the research went to the National Railway Museum and out of curiosity a few years ago, I tried to look at it, but was told it was commercially sensitive to Bombardier. It is my belief, that if this research were to be continued at one of our best universities, that faster freight bogies could be developed, that would help to create the extra freight paths needed on the WCML.
Life-Saving Baby Incubators Uused In Ukraine Pass The NHS Test
The title of this post, is the same as that of this article from The Times.
This is the sub-heading.
The devices made by Mom Incubators weigh a fraction of existing models, making them highly mobile and perfect to use on maternity wards.
The incubator was developed as a final year student project.
- James Roberts founded Mom Incubators in 2014.
- Backers include Sir James Dyson and Holly Branson.
- The incubators have been used in England, Haiti, India, Kenya, the Philippines, Scotland, Uganda, Ukraine, US and Tanzania.
- This is a really wonderful story, which shows the value of good design and keeping the weight down.
James Roberts intends to repeat the excercise with other medical devices.
Hydrogen In Aviation Offers Potential For Growth And Deeper Emissions Reductions, New Study Shows
The title of this post, is the same as that of this press release from Rolls-Royce.
These five paragraphs compose the press release.
Rolls-Royce, easyJet, Heathrow and University College London Air Transportation Systems Lab (UCL ATSLab) published a report highlighting how hydrogen-powered aircraft could enable European and UK aviation to cut carbon emissions while supporting future growth.
The study, Enabling Hydrogen in the European Aviation Market, found that hydrogen in aviation offers a unique opportunity to achieve both emissions reduction and market expansion. The analysis shows that introducing hydrogen alongside Sustainable Aviation Fuel (SAF) can accelerate progress towards net zero, particularly when policy incentives reward low-carbon fuels and if hydrogen were to be included within the EU’s SAF mandate.
The research also found that targeted hydrogen infrastructure at around 20 major European airports, including Heathrow, could deliver more than 80% of the emissions benefits of full hydrogen availability across the continent. Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions, underscoring the value of early technological transition where it is financially and technically viable.
The study is underpinned by UCL ATSLab’s Airline Behaviour Model (ABM), which represents the complexity of airline decision-making through specific behavioural variables. Building on this, the research evaluates how fuel costs, incentives and new technologies shape airline responses. This provides a research-based, realistic picture of how hydrogen adoption could evolve, highlighting both opportunities and potential challenges for adoption.
Note, these two sentences recommending early adoption of hydrogen.
- Concentrating investment at key ‘hydrogen hubs’ would therefore provide a practical and cost-effective path to early adoption.
- Further modelling indicates that the earlier novel technologies, such as hydrogen, can be introduced, the more opportunity they present for CO2 emission reductions.
I also suspect, that introducing hydrogen early, feeds back to reduce Co2 emissions.
But what is Trump’s considered view on hydrogen aircraft?
Google AI gives this answer to my question.
Donald Trump’s view on hydrogen for transportation, including potential use in aircraft, is highly skeptical due to perceived safety risks and effectiveness concerns, which generally aligns with his broader opposition to green energy initiatives. He has specifically criticized hydrogen-powered vehicles as being dangerous and “prone to blowing up”.
Note.
- I used to work in a hydrogen factory and it’s still producing hydrogen.
- I doubt Trump gets on well with Jennifer Rumsey, who is CEO of Cummins, who are one of the world’s largest diesel-engine companies, who are following a zero-carbon route.
- Is Formula One Likely To Go To Hydrogen Fuel? This would set the Cat Among The Pigeons
I also feel that this University College London study will create a string of converts to hydrogen.
US Interior Secretary: ‘No Future For Offshore Wind Under This Administration’
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
US Interior Secretary Doug Burgum said at a press conference on 10 September that offshore wind has no future in the US under the Trump administration and that the government was reviewing five offshore wind projects that are now under construction.
There is also this quote from Burgum.
Offshore wind was too expensive and not reliable enough.
Many of those projects weren’t really about electricity, they were about tax subsidies
I think the fact that the subsidies have been either cut back or limited means that it is likely that there will not be future offshore wind built in America.
He also added that there were concerns that wind turbines interfered with whales and radar systems.
I asked Google AI a few questions.
Is Offshore Wind Extremely Expensive?
Google AI replied.
No, offshore wind is not considered extremely expensive when compared to other energy sources, particularly gas-fired power stations, and its costs are projected to fall further. While initially more expensive to construct than onshore wind due to the marine environment, the higher and more consistent wind speeds offshore generate more power, leading to a competitive or lower overall levelised cost of energy (LCOE) in many regions. Recent economic challenges like inflation and supply chain disruptions have increased costs temporarily, but the sector’s financial position is recovering, and cost reductions are expected to continue.
That looks pretty fair to me.
Is Offshore Wind Reliable?
Google AI replied.
Yes, offshore wind is a reliable energy source because it generates power more consistently than onshore wind due to higher, more dependable wind speeds at sea, and can be integrated with other renewables and energy storage to provide continuous power. Offshore wind turbines operate almost all the time, and the power can be backed up by grid-level storage to ensure a steady electricity supply, even when the wind isn’t blowing.
That looks pretty fair to me.
Are Subsididies And Tax Breaks Important For Offshore Wind?
Google AI replied.
Yes, subsidies and tax breaks are important for the offshore wind industry, which faces high upfront costs and inflationary pressures, to make it more cost-competitive with fossil fuels and secure financing for projects. These incentives help reduce costs for developers, de-risk investments, and ensure the technology can meet climate targets by fostering investment and ensuring long-term viability.
That looks pretty fair to me, but if you were in the oil and gas industry you might think differently.
On the other hand some countries like Norway and the UK, are encouraging the linking of offshore wind farms to offshore oil and gas production to decarbonise offshore operations.
Does Offshore Wind Kill Whales?
This article on the BBC is entitled Fact-Checking Donald Trump’s Claim That Wind Turbines Kill Whales.
It goes into detail about Trump’s claims about wind turbines and marine life.
These are four paragraphs.
“We know what the main threats are to humpback whales: it’s very much the impact from things like fishing and ship strikes,” says Rob Deaville from the Zoological Society of London’s Cetacean Strandings Investigation Programme.
“To talk about wind farms being a problem takes away discussion around the very real threats that are a problem for those species.”
Many other areas with high numbers of wind farms have not seen an increase in whale mortality.
For example, the UK is home to the world’s four largest wind farms, but no humpback whale strandings there have been conclusively linked to the impact of those farms.
That looks pretty fair to me.
But because of our massive portfolio of offshore wind farms and top universities, who research the marine environment, the UK is in a unique position to expose fake science, that was made up on the back of a used envelope.
Does Offshore Interfere With Radar?
Google AI replied.
Yes, offshore wind farms can interfere with radar by reflecting radar signals, causing “radar clutter” or false echoes that can obscure real targets, like aircraft or ships, or create phantom images on a radar display. This interference, also known as a “blade flash,” can negatively impact air defense, air traffic control, and maritime navigation, leading to reduced accuracy and potential safety risks.
That looks pretty fair to me.
Have Wind Turbines Caused Any Air Accidents?
Google AI replied.
Yes, wind farms have caused air accidents, though they are rare. These incidents primarily involve light aircraft colliding with wind turbines or experiencing loss of control due to turbulence from turbine wakes. Examples include a pilot crashing near a wind farm due to turbulence and another fatal crash involving an aircraft hitting a turbine blade.
That looks pretty fair to me.
I learned to fly light aircraft in the 1970s and I remember being told about wake turbulence from airliners, which has been strong enough in some cases to flip an aircraft like a Cessna 150 upside down or into a spin.
What Are The CAA’s Rules For Flying Near Wind Turbines?
Google AI replied.
The primary CAA rule for flying near wind turbines is related to their visibility and safety, focusing on lighting requirements and potential hazards like turbulence. Structures 150 meters or higher require medium-intensity red lights. Pilots must avoid dazzling lights with their own, and wind turbine developers must assess and mitigate risks such as turbulence, radar interference, and impact on Instrument Flight Procedures (IFPs).
That looks like what I would have expected.
Conclusion
I have tried not to be selective with my evidence, but if you are there are reasons that could be used to ban wind turbines.
I am also happy to add any other questions.
I See My First Driverless Car
The pictures show the first driverless car, that I’ve seen.
It was happily going along the Balls Pond Road, where it stopped immaculately at the lights, at the junction with Southgate Road.
Recently, a pedestrian was killed at those lights by a truck. It looks like he didn’t understand the sequence of the lights and stepped out, when he shouldn’t.
As a Control Engineer, I have a feeling, that driverless cars will never live up to the hype.
