Ok, since many people are obviously not reading the article, here's a pertinent figure from it showing the top actions to reduce emissions.
A horizontal bar chart titled “19 climate-friendly choices, ranked” shows actions individuals can take to reduce their carbon footprint, ordered from most to least impactful. The x-axis represents projected impact in tons of CO₂ equivalent per capita per year (tCO₂e/cap/yr), ranging from 0 to about 2.5. Each action is color-coded by sector: transportation (blue), energy (orange), and food (green). Go car-free – highest impact (blue bar extending to about 2.5 tCO₂e). Fly less (blue, about 1.5). Shift to renewable home energy (orange, about 1.4). Switch to EV or hybrid car (blue, about 1.2). Go vegan (green, about 1.0). Walk, bike, or take transit more (blue). Make energy-efficient renovations (orange). Use clean cooking equipment (orange). Go vegetarian (green). Shift driving habits (e.g., carpooling) (blue). Increase telecommuting (blue). Shift to regional/seasonal diet (green). Move to energy-efficient home (orange). Decrease food waste (green). Eat less meat (green). Use less energy at home (orange). Reduce packaged food, dining out (green). Use energy-efficient appliances (orange). Compost – least impact (green, under 0.1). A note clarifies that these are meta-analytic estimates of greenhouse gas reduction potentials, drawn from 659 estimates across 47 academic journal articles. The average person emits 6.28 tonnes of CO₂e per year, though this varies widely by income and country. Wealthier populations may emit up to 110 tonnes per year, while lower-income populations may emit as little as 1.6 tonnes. Source: WRI, based on data from Ivanova et al., 2020.

Germany's Minister of Justice today: "Suspicionless #ChatControl must be taboo in a state governed by the rule of law." Private communication cannot be placed under general suspicion. "Germany will not agree to such proposals at the EU level."

Anlasslose Chatkontrolle muss in einem Rechtsstaat tabu sein. Private Kommunikation darf nie unter Generalverdacht stehen.“

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.

Le Parlement a définitivement adopté mardi la proposition de loi agricole Duplomb-Menonville, comprenant entre autres une mesure décriée de réintroduction sous conditions d'un pesticide néonicotinoïde, et présentée comme une réponse à la colère agricole de 2024.

I worry that escalating war with Iran will be used to whip up more fear and hate for non-white immigrants, particularly those of Arab descent, and be used for unjust deportations.

[ #VeilleESR #ObscurantismeESR ] Polytechnique demande que les étudiants soumettent par écrit leur discours de fin d'année à l'approbation de l'administration.

Je crois que c'est l'exacte définition de la censure.

Des textes portants sur l'écologie, le féminisme et les inégalités ont été censurés.
A Polytechnique, des élèves interrompent la cérémonie de remise de diplômes faute d’avoir pu parler d’écologie sur scène
Une dizaine d’étudiants de la prestigieuse école d’ingénieurs a protesté vendredi 13 juin contre le refus de la direction de les laisser évoquer la question environnementale.

📊 There are *so* many chart types out there. Which one should you use for what kind of data and goal?

I tried to answer the question in a new blog post (and poster!): www.datawrapper.de/blog/chart-t...
A poster showing icons for 40 different visualization types, categorized by goal – e.g. "showing shares" or "showing flows" or "showing developments over time".

L’aide humanitaire en eaux internationales n’est pas « interceptée » = Elle est illégalement arrêtée par Israël.

Les personnes à son bord ne sont pas « interceptées » = elles sont illégalement arrêtées et kidnappées par Israël.

Utilisez les bons mots pour qualifier la situation.

C'est un véritable exploit d'interviewer pendant plus de trois heures le type qui a été élu président de la République en promettant de faire barrage à l'extrême droite sans jamais lui demander pourquoi, sept ans plus tard, l'extrême droite est installée au gouvernement.

Canadian Association of University Teachers recommends that academics travel to the US "only if essential and necessary", and to be careful about what information we have on our electronic devices, especially if you fit into a fairly wide set of categories. www.caut.ca/latest/2025/...
Text of CAUT advice: Given the rapidly evolving political landscape in the United States and reports of individuals encountering difficulties crossing the border, CAUT strongly recommends that academic staff travel to the U.S. only if essential and necessary. In addition, CAUT recommends that academics who fall into the following categories exercise particular caution: Citizens or residents of a country identified in media reports as likely to be subject to a travel ban Citizens or residents of a country where there are diplomatic tensions with the U.S. Travellers with passport stamps evidencing recent travel to countries that may be subject to a travel ban or where there are diplomatic tensions with the U.S. Those who have expressed negative opinions about the current U.S. administration or its policies Those whose research could be seen as being at odds with the position of the current U.S. administration Travellers who identify as transgender or whose travel documents indicate a sex other than their sex assigned at birth Academics should carefully consider what information they have, or need to have, on their electronic devices when crossing borders and take actions to protect sensitive information where necessary.

Meanwhile, S&P is held in a month in San Francisco and there seems to be no plan to switch to hybrid. We've entered the reign of the arbitrary, *everybody* is affected.

Marco Rubio just made the argument, bold faced, not a mistake an intentional statement, that at any time the US can revoke your visa and then you are instantly here illegally and they can arrest you, deport you, torture you, all without any due process.

That means the United States is simply unsafe

I decided to start a #thread 🧵 of stories about legal residents and tourists being (illegally) arrested, detained and/or deported by the Trump regime. I'll only post stories from serious sources, as rumors and conspiracies are really not needed in this authoritarian moment.

"To put things into perspective: I had a Canadian passport, lawyers, resources, media attention, friends, family and even politicians advocating for me. Yet, I was still detained for nearly two weeks.

Imagine what this system is like for every other person in there."

So glad to have successfully defended my Ph.D. last week 😀 Work on producing haplotype-resolved metagenomic assemblies using noisy long reads (HairSplitter) and high-fidelity long reads (Alice assembler, unpublished yet).
Thanks to my advisors Dominique Lavenier and Jean-François Flot ❤️

I made a starter pack for algorithmic genomics. It's certainly incomplete, but already has a ton of awesome peeps. Let me know if you know people I should add (with a focus on algorithms and data structures in genomics)
