☕️ The fungal pathogen Hemileia vastatrix causes Coffee leaf rust that has affected Arabica coffee production for centuries. A new genome of H. vastatrix identifies a haploid trisomy that could be responsible for the pathogen's changed virulence profile. 🔗 buff.ly/Tf9AoeS 📷️ @peritob.bsky.social

As a Nobel Peace Prize laureate, I want to address the people of America, regardless of their political views. Do you really believe that the killing of millions of people and the loss of Ukraine's independence are in your national interest?

Right now, Russia is striking Kyiv with ballistic missiles. Zelensky says that, once again, there was no warning from our partners. It looks like the Trump administration did, in fact, order a halt to intelligence sharing with Ukraine.

17 murdered in Zaporizhzhia today. 22 in Pryluky a couple of days ago. 33 in the Kramatorks buses. Over just a week. After 9/11, America could have probably understood what is large-scale terrorism. 25 years afterward, their administration is happy to sponsor it. Dark, dark times.

Daniel never finished his home assignment. At around 8 a.m., a Russian het drone struck his apartment building in the center of Kyiv. Daniel was killed in his room. Among the wreckage of the family’s apartment, his school notebook remained open.

This is the unfinished homework of 14-year-old Daniel Umansky. On the morning of September 25, Daniel was sitting in his room in Kyiv, doing his homework.

Russian strikes are incoming from all sides onto #Kyiv, in broad daylight. Markets, gas stations, a hospital, office, kindergartens, residential buildings. Russian scum cannot push through on the front line, so they are staging genocide in Ukrainian cities.

🪵 Le volume de bois mort dans les forêts françaises a été multiplié par cinq en vingt ans, pour atteindre 25 mètres cubes par hectare. Mais ce n’est pas une source d’inquiétude, au contraire !

Melampsora rusts can be difficult to identify, but I think the galling behaviour of this one on Salix caprea found today along Lakenham Way in Norwich means that it has to be Melampsora caprearum.
