@GavithaS @kshitijjgulati @nmegdanov @RathorNishant19 @DannyDKoit @PankajBansal128 @NewsWireLK Yes network connectivity up and running again.

@kshitijjgulati @HaanXander @nmegdanov @RathorNishant19 @DannyDKoit @PankajBansal128 @NewsWireLK Just wanted to confirm. Did you all contacted your family? Network is working but travel restrictions are still on

Flood situation in Gampola continues to worsen. Water has now risen up to the 2nd floor of this house, forcing residents to seek higher ground as rescue teams struggle to reach the area due to blocked roads and heavy rain

@GavithaS @nmegdanov @kshitijjgulati @RathorNishant19 @DannyDKoit @PankajBansal128 @NewsWireLK Just got in touch with them. They are okay!

@GavithaS @nmegdanov @kshitijjgulati @RathorNishant19 @DannyDKoit @PankajBansal128 @NewsWireLK Hi, does anybody know anything about the situation in/close to the travellers inn lodge in Nuwara Eliya, where probably my daughter (Iris de Haan, traveling with Max and Marieke) is staying?

@GavithaS @nmegdanov @kshitijjgulati @RathorNishant19 @DannyDKoit @PankajBansal128 @NewsWireLK Sorry travellers nest inn/king’s lodge

🧬 Insights from #ESWI2025! Dr. @HaanXander showed human respiroviruses preferentially bind 2-3Sia 🔑 but can also engage 2-6Sia via heteromultivalent binding 🫁 — explaining infection of the upper respiratory tract. #Virology

Very cool study by Adinda Kok from her time in Rotterdam. Lucky to have her with our team in Utrecht now. nature.com/articles/s4158…
