While I think having a Labour government is far, far better than having certain other governments in this country, this Bill, in my scientifically-informed opinion is terrible and anti-nature. These releases, while they would be good, demonstrate a glaring hypocrisy.

Yes, this is all well and good, from the same government who have basically said "F*** you" to our country's wildlife by passing this: www.gov.uk/government/n...

The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s β€œhard to be brilliant if you are worrying if you look fat or why another woman hates you.”

In 2018, an elite group of academics and scientists planned an exclusive retreat. The guests were picked by prominent New York literary agent John Brockman.

The problem? Brockman added two women to the list, and his biggest funder β€”Β Jeffrey Epstein β€” wanted them out.

Marsh Clubmoss (Lycopodiella inundata) shoots creeping across a wet, bare substrate. The shoots are bottle-brush like, bright yellow-green with narrow, untoothed leaves sticking out from the main stem.

**BREAKING NEWS** - Marsh Clubmoss refound in Dunbartonshire, at a site where it was last recorded in 1854!

Being more-or-less evergreen, clubmosses make great botanical targets all year round. With that in mind, I set out to hunt for Marsh Clubmoss near Inveraran on the shore of Loch Lomond 🧡

It is rare to find this abundance of Polypody on a Pedunculate Oak in Sussex. Clapham Woods. Dip-slops South Downs ancient woodland, on chalk (Tarrant Chalk) near Worthing. A rare form of ancient woodland. @bsbibotany.bsky.social #southdowns #ancientwoodland #polypody

New research shows that by 2050 global yield losses linked to extreme heat at flowering could rise by about one-third. By 2090, those losses could increase by more than 75%.

No wonder that Edge, edited by John Brockman, was incomprehensible and a slog to get through. Almost DNF. I hadn't realised that all of those interviews that I read, conducted around the early 2010s (if I remember correctly), had such toxic, racist and misogynist undertones.

I've been fascinated by animals in this phylum since I first read about them in about 2015. I'm so delighted that research into the Xenoturbella genus is still very much ongoing and that these fab additional species have been discovered.

Decline in botanical education threatens response to climate action and food security

*Decline in botanical education threatens response to climate action and food security*

Early, hands-on encounters with plants, inspiring mentors, and emotional connections to nature are among the strongest drivers behind choosing a plant-related path.

We really are living in a terrifying society, absolutely galling that the Home Office can get away with such a hostile tweet.
