Another lovely long walk at a local nature reserve. Historically on a day like today we'd have wandered round York, had lunch, met friends for a drink. But 7yo loves the outdoors and it's so much less stressful being in nature in the new Covid-world.

I think the damselfly is a beautiful demoiselle, the toad is just a common one that let the 7yo handle it, but I would love to know what the beetle is - we were looking for Tansy beetles, but found this instead.
Actually a male banded demoiselle.

Timely to highlight the life and work of Ben Barres.
Ben was a remarkable biologist who transformed our understanding of brain function. Born in 1954, he transitioned from female to male in the late 1990s. Image
In his research, Ben and his team gained an understanding of glial cells, and importantly showed that astrocytes could damage the brain - an important breakthrough in terms of understanding a variety of neurodegenerative disorders. Image
Ben wrote eloquently about the process of transitioning, reflecting: “I am not aware of a single adverse thing that happened to me as a result of my being transgender, but there was immediate relief of all emotional pain as a result of my transition.”

It's timely to highlight the life & work of computer scientist Lynn Conway.
In the late 1960s, she transitioned from male to female and was sacked by IBM as a result. For some years, she went underground and, for the rest of her career, worked as a woman - herstory unknown. Image
Under the legislation of the 1960s, Lynn was denied all access to the children she had previously had with her wife.
Lynn went abroad for her surgery, all alone. She had lost not only her career and professional reputation but also her family, relatives, friends, and colleagues.
In the late 1970s, working (in her words) in 'stealth mode' as a woman, Lynn developed very large scale integration (VLSI) of computer components, a key breakthrough in computer science, which enabled the modern computer and ultimately put smartphones in everyone's pocket. Image

On autism/ADHD & behaviour.
Over the weekend, I have read lots blaming autistic children for their behaviour, or suggesting poor parenting is to blame.
Autism & ADHD are *disabilities* that can impact on behaviour - to fail to understand this is simple disability discrimination.
When neurodivergent children are dysregulated, and in a bad environment, they can struggle to behave.
This is an inherent part of their disability.
You cannot 'make' them behave by shouting at them, in the same way you cannot make a blind person see by yelling in their face.
Schools cannot 'make' neurodivergent pupils behave by giving them a suspension - you wouldn't expect someone in a wheelchair to start walking because you sent them home for a week. Autism can be just as disabling.
The way to address it is to build an inclusive environment.

In 2018, trans rights were broadly accepted - even Theresa May proposed legislation to treat trans people with dignity. In 5 years, Stock, Bindel, Rowling, et al, have created a toxic environment where trans people are demonised and fear for their safety. That's their legacy.
This Pride, all I read, is hateful & degrading rhetoric against trans people. Although gender critical people have the right to believe what they want about sex, that does not give them carte blanche to abuse trans people or discriminate against them in the provision of services.
I urge people to meet real trans and non-binary people, talk to them, understand them as individuals. Phobias feed on 'othering' people - once you count someone as a friend, phobias melt away. We are all human - this Pride can we try and see others as human.

Bempton Cliffs - Seabird City. England's best onshore seabird colony. Didn't get lucky with puffins today, they are mostly egg-sitting in their burrows, but the gannets and razorbills were great.

Followed by North Landing, Flamborough. @YorksWildlife ImageImageImage
Where my highlight bird was actually a kestrel hovering and hunting the shoreline scrub (failed to get a good photo though). ImageImage

29 scientists write about 'merit' in science and use this figure to 'measure' it. First, I should emphasise we all want great science. Also, merit is not opposed to diversity as the authors suggest - noone wants bad science. The problem is those axes...

Who decides importance?
Is it scientists who go to conferences with buddies and set agendas?
Is it editors based on what gets cited?
Is it rich governments deciding national priorities?
Is it disadvantaged citizens in developing world?
All have different views and priorities.
When we get down to individual levels, and recognising scientists, should we consider resources used? Is it more meritorious to develop a new chemical reaction with a team of 60 and huge national funding, or a team of 2 and a little local support? Simple measures ignore context.
