Les tiques peuvent transmettre aux humains la maladie de Lyme, très grave, mais aussi d’autres affections. Pour mieux les comprendre et améliorer les traitements, les chercheurs disposent désormais d’une « tiquothèque » de 80 000 spécimens.

L’Assemblée nationale abandonne définitivement les ZFE La suppression des zones à faible émission (ZFE) à l’Assemblée nationale, ce mardi 14 avril 2026, est une parfaite illustration du backlash

Il y a de quoi être en colère. La droite et l'extrême droite viennent d'enterrer les ZFE, ces Zones à Faibles Emissions qui peuvent éviter des milliers de morts par an.

40000 morts de la pollution de l'air en France chaque année, mais l'AN vient de les supprimer.

Rust fungus Puccinia chaerophylli on a leaf of Sweet Cicely, Myrrhis odorata. Leaf midribs swollen and distorted by yellow aecia. Last September I found rust-coloured uredinia and brown telia on stems and leaf undersides of the same plants.

Not particularly common in Norfolk, considering it also occurs on Cow Parsley, Anthriscus sylvestris.

The EPA is forcing 124 of its scientists and researchers to accept reassignments and 35 of them are being told to pack up and move to a new city if they want to keep their jobs.

We teach at a Florida university that agreed to cooperate with ICE – and we worry that it is making our students feel less safe At least 15 Florida state universities and colleges have signed agreements with Immigration and Customs Enforcement that authorize campus police to carry out immigration enforcement.

Florida universities are partnering with ICE, giving campus police power to question and arrest students over immigration status.

Two professors there warn it’s creating “an intensifying climate of uncertainty and anxiety” on campus.

#Rust of moschatel (Adoxa moschatellina), with both species #Puccinia albescens (aecia) and P. adoxae (telia) on the same leaf stem (Les Clayes-sous-Bois, FR).

#Rust of moschatel (Adoxa moschatellina), caused by #Puccinia albescens, here with aecia, uredinia & telia on a single leaf (Les Clayes-sous-Bois, FR). The telia differ from P. adoxae: evenly distributed on the underside without causing deformation, also releasing urediniospores.
