Sheffield campaigners launch bid to buy Moscar Moor for community Moscar Moor is not for sale, but the group hopes to secure it under new Community Right to Buy law.

Sheffield campaigners launch bid to buy Moscar Moor for the community

Local Labour councillor Minesh Parekh said: β€œI look forward to people making use of the upcoming 'Community Right to Buy' legislation to bring mismanaged land into community hands”

Starting a scrap while a player is down injured and then saying β€œhe’s fine” over and over again before he’s carted off? Yeah there’s a limit and that was way past it.

My response to those who say it’s β€œtoo late” to address climate change and global environmental damage.

It is NOT too late. As long as one tree is still standing, one whale is still swimming, and one child is still breathing it is not too late to protect something precious.

These books just arrived. Our new crop pollination book with info about fruits, vegetables, bees an conservation measures came out 😊 I hope we will also produce versions adapted to other countries.

Intelligence on Earth Evolved Independently at Least Twice Complex neural circuits likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.

Today we can announce a panel of judges has found:

- The ecological case against industrial sandeel fishing is sound

- The UK has the right to stop this damaging fishing in its waters

This means sandeels can be safeguarded for the seabirds that need them.

The image presents a comparison between two types of lawns to promote #NoMowMay. On the left side, titled "Why have a lawn like this?" it displays a grid of uniform green squares representing a plain, regularly mowed lawn. On the right side, titled "When you can have a lawn like this?" the grid intersperses colourful icons of a sunflower, a pink flower, a ladybug, a frog, a bee, a butterfly, a white flower with a yellow centre, a tulip, another sunflower, a red mushroom with white spots, and additional flowers, symbolising a lively, biodiverse lawn encouraged by letting grass grow naturally during May.

6/6. Where do we go from here?
Further investigation, especially into exposure to modern
contaminants is required.
Monitoring wild populations should be prioritised, screening of chemicals should be improved & carried out before approval for use.
The effects of chemical mixtures are still unclear.

5/6. We found high confidence that DDT causes eggshell thinning & at least some
evidence that all investigated contaminants bar PFAS can cause EST.
Endocrine disruption is more investigated than eggshell thinning.
Papers on EST are more observational whereas ED are more experimental

List of authors of the direwolf genome preprint, including George R R Martin

I know lots of research labs who don’t include undergrad lab assistants as coauthors on papers, because they just followed instructions and didn’t make a serious intellectual contribution.

But sure, putting a fantasy author who funded your work as a coauthor screams β€œserious science, not a stunt.”

Trump team cites wolf β€˜de-extinction’ as reason to cut endangered species list The interior secretary hailed a biotech company’s claim to have brought back the dire wolf, while the administration and GOP push to roll back species protections.

Everyone who told me "what's the harm in hyping de-extinction technology that doesn't work" can choke on a bag of black-footed ferret dicks

in case you're wondering, "what's the harm in claiming an extinct species has been brought back from the dead" when it most certainly has not, our interior secretary is already using it to justify taking animals off the endangered species list

Hi, I’m Becki Lawson, a wildlife vet at @zslofficial.bsky.social, and today I will be exploring disease surveillance in wild birds in light of the overall health of people, animals, and the ecosystem – in short: One Health.

3/6. We are now producing more chemicals than ever before. At the same
time, β€œlegacy” pollutants remain in the environment despite ceasing production due to their persistence. We investigated the literature to determine whether 6 focal
pollutants have a potential to cause eggshell thinning.

2/6. Historic eggshell thinning, attributed to the pesticide DDT, and caused increased reproductive failure as eggs were crushed or failed to hatch. This contributed to population declines in many species and several mechanisms have been put forward by which pollutants might cause this.

1/6. Are modern contaminants causing eggshell thinning in birds? In the first chapter
of my PhD I have completed a systematic review evaluating whether 6 contaminants
cause eggshell thinning by assessing the volume of & agreement in the literature.

Ireland are way more aligned with Leinster from a style perspective than last season.

The difference is that Ireland are playing generally better teams with deeper squads that don't fall off after 60 minutes when Leinster bring on Snyman and Barrett.
