How can we communicate science in a society that is growing more polarized?

Tackling hate speech, anti-elitism, anti-rationalism, mistrust in scientists & populism were all discussed at SciComm 360° ➡️ www.avcr.cz/en/news-arch... @maxplanck.de @tomaskoblizek.bsky.social @flu-cas.bsky.social

❄Cílem projektu je zhodnotit kontaminace věčnými chemikáliemi z lyžařských vosků v modelovém území chráněné oblasti CHKO Jizerské Hory.
Závodníci fluorové vosky už používat nesmí. Pro rekreační lyžaře zatím podobný zákaz neplatí. Jak vypadají průběžné výsledky👇

Vyšší koncentrace než v čističce. Vědci z Akademie věd zkoumají zamoření jizerských stop fluorovými vosky
Nemažte lyže vosky s fluorem, škodí zdraví i horám - apelují na lyžaře mikrobiologové. Profesionální lyžaři fluorové vosky už používat nesmějí. Rekreační lyžaři je ale do stop stále zanáší.

Proč dal mikrobiolog Rufin Kouipou přednost Česku před Japonskem? V rámci MERIT hledá v @mbuavcr.bsky.social nová antibiotika. 🦠 Rufin vysvětluje, proč je pro vědce stabilita důležitější než prestižní, ale krátká stipendia. Oceňuje českou otevřenost i přímočarost.

The fungal skin pathogen apparently helps itself by producing toxin-like substances that facilitate infection of new hosts.

These substances can suppress the immune response and thus accelerate the spread of the pathogen among humans.

Today is the International Day Against Violence and Bullying at School.

An ERC-funded research has revealed that bullying triggers the same stress responses in the brain as physical threats.

Let’s continue raising awareness, offering support, and speaking up.
