Here's an article I recently wrote for @newscientist.com

The mysterious link between sleep disorders and reductions of a microbe called Faecalibacterium, which breaks down fibre - teasing evidence for an interplay between fibre, the gut microbiome and sleep. 🧪

Microbiome study hints that fibre could be linked to better sleep
Evidence is mounting that specific gut bacteria are linked to sleep conditions, which may open the doors to dietary recommendations aiming to boost the quality of our slumbers

This news article I wrote went up last week in @nature.com and it really reiterated to me just how important a wide scope is for multi-omics atlases. The more people we can include and the greater the range of ancestries, the more new science will be unveiled 🧪

And no, it's not a jellyfish, it's a comb jelly

Excellent, damning analysis of the video of the killing of Ms Good, from the NYT, including a quick debunking of the “evidence” the President showed other Times reporters last night.

Video: Videos Contradict Trump Administration Account of ICE Shooting in Minneapolis
An analysis of footage from three camera angles shows that the motorist was driving away from — not toward — a federal officer when he opened fire.

Terribly sad. And also so unsurprising. It's like everything the Trump administration represents (e.g. dictatorial action, erosion of democratic norms, instability, terrorising people, excessive force, deception, repression of free speech) distilled into one moment www.bbc.co.uk/news/article...

I love when a paper makes me feel stupid by finding an obvious, overlooked solution: “perhaps most great whales have an unrecognized potential for great longevity that has been masked by the demographic disruptions of industrial whaling”; we killed all the old ones, only the babies are left. Duh. 🧪

I loved digging into this one for @livescience.com. There is video evidence of #dolphins and killer whales hanging out together on hunts. Are they really cooperating, or is something else going on? #science #orcas #killerwhales #behavior #marinelife

Have a look through this gallery to see one of the coolest examples of role specialisation in the insect world 🐜

They live inside twigs with small circular entrances & these workers have evolved heads the perfect shape to block those entrances - effectively, they are living doors!

Nice to see these very forthright words from European Council President António Costa @eucopresident.consilium.europa.eu
Finally an EU leader hits back vs US NSS - Costa:

"US no longer believes in multilateralism, rules-based order, climate change. We have differences in our worldviews. The strategy continues to speak of Europe as an ally. That’s good. But if we are allies, we must act as allies..

Well this is an exciting message from Evri:

It is well known that #exercise is linked to better #cancer survival, but the mechanisms behind this are poorly understood.

It now seems tumour growth is reduced by exercise due to muscle cells outcompeting cancer cells for sugar. @newscientist.com #health 🧪

We now have a greater understanding of how exercise slows cancer
Tumour growth is reduced by exercise due to a shift in the body’s metabolism that means muscle cells outcompete cancer cells in the race to get sugar to grow

Pregnancy is linked to greater risk of dental issues, but we aren’t entirely sure why.

Now, it seems that the oral microbiome changes when a woman is expecting, becoming less diverse and potentially more prone to causing inflammation. 🧪 #health #pregnancy

Upheavals to the oral microbiome in pregnancy may be behind tooth loss
Dental problems often arise or get worse during pregnancy, and a new study hints that rapid changes to the oral microbiome at this time could be at least partly to blame

It also makes we want a leopard cat (a "chicken-killing tiger"), but apparently although they are adorably cute only for the first month, after that they go WILD
