The articles raise interesting questions. Should you trust the counterfeiters? Probably not. But should you trust the makers and sellers of "genuine" kits? Also probably not. Both seem aimed to maximise profit for minimum expenditure rather than to produce a quality garment.

Especially as BBC Sport ran this story last year about the "cost" of replica shirts, which felt a little like an opinion piece arguing that people should buy genuine kits. It made me uncomfortable to read it. www.bbc.co.uk/sport/footba...

Fake football kits can be as much as £70 cheaper than the real deal, but experts have raised concerns they could be harmful.

...but there were many types of salamander in the waters of this temperate world packed with plants and insects, which is probably one reason new semi-aquatic mammals that could feed on them keep cropping up

If you look carefully, you can see a salamander lurking in the corner of the illustration of this Jurassic platypus-like animal, Megacauda sungei. There were oodles of salamanders around during the Jurassic. The one in this illustration seems like a newt eft or an axolotl to me...

I enjoyed covering this one for @livescience.com, especially the description of an ancient mammal relative being "like a chimera", with the back being like a platypus, but the front sporting sharp teeth for rending prey. If only the prey weren't salamanders - one of my favourite animals. 🧪 🐸 🦊 🐍 🦇

Any idea why they would swarm like this? Is it because they've all just emerged and so there's a mass meet-up for mating, a bit like frogs sometimes do?

So the blooms, pretty as they are, are probably best removed, for the sake of the tree and your future crop.
020
Chris Simms @chrisnsimms.bsky.social · 01/10/2026
If this is happening to your tree, be aware that any pears that start to develop in autumn are exceeding unlikely to make it. They will just use up the tree's energy stores, leaving it more vulnerable to disease over winter and potentially reducing how much it flowers and fruits next year.

Chris Simms @chrisnsimms.bsky.social · 01/10/2026
I imagine this is something we will see more and more as climate change brings increasingly hot, dry summers and mild, wet winters.
100
Chris Simms @chrisnsimms.bsky.social · 01/10/2026
The mechanism behind it isn't clear, but it is thought drought conditions make trees go into survival/dormant mode and when mild, wetter conditions arrive, the tree reacts as if it is spring. This pear tree doesn't look vigorous - it has lost most of its leaves early - as it might for winter.

Good question. Maybe it would work cutting sugars down once the antibiotics are prescribed, but also I suspect getting a prescription for antibiotics is rarely a surprise to people. People tend to have some signs of illness that prompts a visit to a doctor, so there is a warning period.

The research that shows this has been done in cancer patients, but given that experiments in mice back it up, it seems reasonable to expect this principle to apply to people generally

Chris Simms @chrisnsimms.bsky.social · 30/09/2026
For every 100-gram increase in high-sugar foods during the 24 hours before an antibiotic dose was taken, the drop in total bacterial diversity was on average 24 per cent greater.

Still buzzing with joy at finding all these craneflies, or daddy long legs as we call them in the UK. I was told long ago that there's a local name for them in Finland or Sweden that translates as "something in your hair". Anyone know what that word is? (Google doesn't seem to know)

Although the craneflies don't look very mobile in these pictures, they were all wriggling away. Other smaller groups of them were gathered on the lee of large cowpats nearby. Not sure about the species because they were wriggling so much. Tipula of some kind. Tipula paludosa?

The study authors suggest it is a systemic effect, and the exact cause isn't known. The current thinking is more that it is the cumulative action of all sorts of molecules circulating around the body, often via the blood stream, which heal damage, clean away rubbish and protect against harm

Which is, on the one hand, great news for possible ways to hold off or reverse some of the effects of ageing on our bodies or organs. But, on the other hand, it also hints that some aspects of ageing may simply be irreversible and no one will be able to resist the tick of time forever.

Perhaps what I found most interesting about this research is that it looked into what functional difference was made by changing the biological age of a heart. Many functions in a rejuvenated heart improved, but not all.

The find is both surprising and yet makes sense given previous work in which living organisms were surgically joined so they shared a single circulatory system. Those studies showed that the blood of young mice extended the lives of older ones to which they were connected and boosted cognition.

Chris Simms @chrisnsimms.bsky.social · 28/09/2026
The work is based partly on studies in mice but then also shows that the same ageing/rejuvenating effects are seen in samples taken in the course of past human transplants.

Chris Simms @chrisnsimms.bsky.social · 28/09/2026
Young donor hearts become biologically older in an old recipient, and an old heart gets biologically younger in a young recipient! The big implication: this could increase the number of organs available for transplant. My latest new story for @nature.com 🧪 #health www.nature.com/articles/d41...

Well... In British English it tends to be more relaxed and "fish" can be used to mean one fish, many fish of one species, or many individuals of different fish species. Some people treat "fishes" as the scientific plural to indicate multiple species, some regard that as archaic and stick with fish.
