The smell of rain: how our scientists invented a new word

Have you ever noticed that fresh smell of earth in the air just before it starts to rain? Well, there's a word for it - petrichor.

A/Prof Sam Stehbens PhD (She/Her) @samstehbens.bsky.social · 2h

Ever wondered why it smells when it rains? Defined by #Australian scientists in 1964 in #Nature as ‘petrichor’ >derived from the Greek word for stone & the blood of mythological gods.

This is so disappointing. Fundamental **aka DISCOVERY ** science underpins training of the next generation of scientists, irrespective of if they go into translation labs or not. Failure to support it = turning off the tap. No discoveries, nothing to translate. Weak workforce #NHMRC

Sophia Davidson @sciencesophie.bsky.social · 2d

My major note? It completely leaves out fundamental research as a priority 🤯

Which is wild, #NHMRC’s job is to "support the highest-quality research, from 👉BASIC science👈 through to clinical, public health and services research" (NHMRC Corporate Plan: nhmrc.gov.au)

A mechanical origin for implantation defects in embryos from aged females

Women over 35 experience a marked reduction in fertility. The origin of these fertility defects appears to reside in the implantation capacity of the embryo itself, but the mechanistic basis of this i...

If anyone ever wants to brush up on a lot of cell migration concepts don't forget we have several wonderful scientists who have given talks previously in cell migration seminars. I find it so comforting to go look at old videos, maybe someone else who will do as well!!

EACR Goodbye Flat Biology in Germany was fun- reconnected with old UCSF crew. Learnt some amazing science and made some new friends. One of the best cancer conferences I have attended. (Looking forward to seeing my kitties at home!).

On #worldcancerday it has been humbling to be surrounded by a truely impressive cohort of cancer scientists at @helloeacr.bsky.social ‘s Goodbye flat biology conference. We need to keep investing in research to make sure we can create impact in this space.

Eric found multiple roles for microtubules in tissue-resident macrophage homeostasis and function -- including in helping macrophages navigate around epithelial obstacles during wound repair👇

Have you ever wondered how microtubules withstand and respond to mechanical stress in cells?

Here we show by in vitro reconstitution assays that MAP65-1 and PRC1 promote microtubule nucleation on existing lattices, especially on those with structural irregularities linked to mechanical stress.
