Hybrid working from home improves retention without damaging performance - Nature A trial investigating the effects of a hybrid working schedule in a Chinese technology firm in 2021–2022 shows that working from home two days a week improved job satisfaction, reduced quitting and did not affect performance.

Huntington's disease successfully treated for first time One of the most devastating diseases finally has a treatment that can slow its progression and transform lives, tearful doctors tell BBC.

MicroRNAs at the centre of this success story for treatment of Huntington’s disease.. truly wonderful and inspiring progress. Well done to all involved : www.bbc.co.uk/news/article...

🧪microRNA treatment success for Huntington's disease announced. It sounds promising but hasn't published yet. Will it pass the peer-review sniff test? Will it get licensed in the US in 2026?

Also, how did it take this long for me to realize BBC doesn't use the Oxford comma?

There are two weeks to go in the fundraising campaign for the Natural History Society of Maryland's new shark science and conservation exhibit, and we have to raise about $1,400 more.

Please consider chipping in to help. Thank you!

Can we get to 1004+ new ctenophore observations to celebrate? Are you ready for the Cteno Day Bioblitz? Join today! inaturalist.org.projects/ctenophore-day-2025

It’s almost Ctenophore Day! I set up a BioBlitz on @inaturalist.bsky.social to celebrate. Spread the word, and let’s see how many people we can get out looking for ctenos!

This is figure 1, which gives an overview of the methods used to generate artificial mimetic stimuli.

Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance, according to a study in Nature. go.nature.com/44yj4M5 🧪

Take a look at our work on miRNAs and their involvement with placental phenotypes. It's great to see this work finally see the light of day - huge thanks to everyone involved with the manuscript.

Mammal placental phenotypes are predictable from microRNA repertoires. Despite >100 million years of mammal diversification, similar placental morphologies have independently evolved multiple times, presenting a long-standing evolutionary puzzle: what genetic mechanisms ...

When you see convergent phenotypes do u wonder about their genetic basis? Did they re-invent some genetic element to construct the phenotype? The mammal placenta-a pretty important organ-has a lot of convergent phenotypes & this paper helps explain how they come about www.biorxiv.org/content/10.1...

Happy to have contributed to this paper!!! Convergent placental phenotypes are mechanistically shaped by the same regulators

How did mammal placental diversity evolve? miRNAs play a significant role - indeed their repertoire is predictive of phenotype. Congrats to all: esp 1st author @jfennbio.bsky.social & all in @niamhforde.bsky.social group. Thanks to @ukri.org and @leverhulme.ac.uk. www.biorxiv.org/content/10.1...

Geophysicist and seismologist Inge Lehmann was born #OTD in 1888.

In 1936 she discovered the existence of a solid core at the center of the Earth, based on a careful analysis of global seismic records from a 1929 earthquake near New Zealand. 🧪 👩‍🔬

The Dire Wolf Isn’t Back—But Here’s What ‘De-Extinction’ Tech Can Actually Do Colossal Bioscience says it has “de-extincted” the dire wolf, but other scientists disagree and say more important conservation science is being lost in all the hype

Amidst all the hoopla about "dire wolves" some potentially quite important developments for protecting endangered species is being a bit lost. Wrote about that and other aspects of this whole thing: 🧪
