La série noire (et elle ne fait que commencer !) continue : près de 43°C enregistrés aujourd’hui en France, avec 57 records battus, dont 24 records absolus.
En 2025, 598 records de chaleur contre seulement 15 records de froid.
🔴Soit 40 fois plus de records chauds que froids.

Canceling NIH grants is a great example of waste, fraud, and abuse. Even canceling just my grant alone, in year 3 of 5, would be a waste of the more than $1M already given to us for this project. Multiply that by hundreds of grants, and they are just throwing away taxpayer $$$. And for what? +

Happy #WorldWetlandsDay! 💧

Today, let’s celebrate the central role of #wetlands in our lives!

They increase resilience to #ClimateChange, support #biodiversity, filter water & contribute to #foodsecurity.

Preserving & restoring wetlands is essential to limit severe flooding from heavy rainfall.
Up: 5 circles illustrating rivers, floodplains, marshes, estuaries, and mangroves. Down: 4 squares to illustrate how wetlands degradation contributes to floods: 1) a river and a marsh, with natural soils; 2) channelization of the river and drainage of the marsh; 3) land conversion to urban areas and agriculture; 4) heavy rain causes severe flooding.

Happy to start 2025 by sharing our new preprint biorxiv.org/cgi/content/... -the first paper from our BBSRC collaborative project with
@richardmott.bsky.social and Kathryn Lilley to understand what controls protein abundance in plants. 🧵 1/9
Genomic information pathways and their numerical linkages in relation to the Central Dogma. The boxes show different omic levels in Col-0 and Can-0. Black arrows indicate the flow of information implied by the Central Dogma starting from CDS (peach) via gbM (green) to mRNA (light blue), ribosome-associated mRNA (yellow) and finally protein (pink). The strength of Pearson correlation between levels is shown both by the numbers and by the thickness of the corresponding black arrows, and represents the correlation between quantitative expression levels (except in the case of CDS where is represents the correlation derived from the multiple regression codon frequency model, i.e. the square root of the fraction of variance explained). The merged arrows connecting CDS, gbM and mRNA to protein show the result of combining information into a single model; note that their combined correlation of 0.720 is less than the sum of their individual effects. The correlation of tRNA levels (lilac) with genome-wide codon and amino acid frequencies is shown on the left. The correlations between corresponding Col-0 and Can-0 omic levels are shown next to the grey double-headed arrows.

💡 Did you know #soil is the largest carbon reservoir in the terrestrial ecosystem?

🚨 Accurate estimation of soil C is crucial to addressing pressing issues such as #ClimateChange, #FoodSecurity, and #biodiversity conservation.

Learn more about the different soil C measurement methods ⬇️
#scicomm
Soil Organic Carbon Measurement Methods. At the top, 5 methods are mentioned from left to right. * Novel sensor technologies * Hybrid (satellite + high-resolution sensors), a promising approach * Core sampling & lab analysis, the gold standard * Hybrid (satellite + lab) * Satellite imagery Each method is illustrated with corresponding icones : soil with probe and portable device for Novel sensor technologies, soil with soil core sampling going in an erlenmeyer flask, satellite. Below is an indication of accuracy with line thickness, peaking at the center below the core sampling and lab analysis method. Novel sensor technologies present a good accuracy, and satellite imagery a relatively low accuracy. Then drawbacks are quantified with line thickness as well. Greater drawbacks for core sampling & lab analysis, then for satellite imagery, and novel sensor technologies present the lowest amount of drawbacks.
