Living with ME/CFS
This is so validating, and the much-needed first step into understanding the causes of ME. Candidate genes affecting the immune and nervous systems align with my and others' experience but now it's time to fund more in-depth research.
Our initial DNA results! DecodeME have discovered that people with an ME/CFS diagnosis have significant genetic differences compared to the general population.

What's the true value of a hedgerow? Or a diverse landscape when it comes to mitigating field edge yield declines? Our new paper out today might have some of the answers doi.org/10.1016/j.ag...

Started a new #ReverseMentoring relationship with a senior leader from @pirbrightinst.bsky.social this week. I love that BBSRC institutes are investing in EDI and I'm excited for our conversations about disability and chronic illness in the workplace #pwme #mecfs

The glyphosate debate
The EU has recently approved the use of glyphosate for another decade. Bárbara Pinho examines the controversial pesticide's presence in British farming and considers the possibility of a ban in the UK

A brilliant example of the tradeoffs between soil health and weed control when thinking about min till
The plough has been a good scapegoat for wider systemic neglect of soils. I had some thoughts after learning the hard way about jumping too fast into removal of ploughing as a tool. nathannelson.co.uk/2022/10/soil...

An interesting article on soil health and tech just popped up on BBC News. A great introduction to issues around soil health, it covers quite a bit around the emergence of new technology and how it ca...

There's always a new challenge in Agriculture, let's not let the news today of glyphosate resistance in the UK prevent a positive transition toward more regenerative practices
The transition to regenerative agriculture in the UK could be hampered by the evolution of weeds resistant to the herbicide glyphosate for the first time 🧪 🧵 1/
(they've long been a problem elsewhere in the world, of course)

Glyphosate-resistant weeds have evolved in the UK for the first time
The herbicide glyphosate is helping farmers adopt more environmentally friendly practices, and resistant weeds will make this transition more difficult, experts say

A glyphosate-resistant weed has been found on a UK farm for the first time, raising the spectre of a new pressure on British farmers.
Researchers have confirmed that Italian ryegrass (Lolium multiflorum) on a farm in Kent was resistant to the weedkiller glyphosate.
Story soon.

taking advantage of the fact that 2025 is a square and therefore it's the sum of all odd numbers from 1 to 89!

What a reading year I've had! I can't believe I read 87 books in 2024! Choosing to read for an hour before bed instead of watching TV has been easier on my nervous system and reduced my sensory symptoms. I gave 15 books 5⭐️ By diversifying my reading I 1discovered new favourite authors and genres!
