🚨 New Perspective alert: Why do standard defect models fail for #2DMaterials? This article examines the unique physics of defects formed by #ElectronIrradiation and #IonBombardment and identifies critical gaps in our current understanding of defect behavior.  ➡️https://tinyurl.com/37xt9wyc #BJNANO 💎🔓

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

For International Women’s Day, we’re highlighting the contributions of just a few EFF Award recipients from the last decade, whose work to protect privacy, speech, and creativity online has had a global impact. www.eff.org/deeplinks/2...

You know what to do

Ich bin so alt dass ich mich noch daran erinnere, dass bei einem Krieg über die Zerstörung und die Opfer berichtet wurde, und nicht über die Probleme für die Reisebüros.

Today is the day of Kullervo! The archetypal Finnish hero has his tribe slaughtered. As a slave child, his owners try to hang, burn & drown him. When he grows up, he sleeps with his sister who drowns herself in horror. He asks his magical sword would it drink his blood & the sword says yes. It does

Kidical Mass Vienna rolls out on May 9, 2026 🚲 A family-friendly bike ride advocating safe cycling infrastructure and child-friendly streets. Join the movement for protected bike lanes, safer intersections, and a city where children can ride safely and independently. www.kidicalmass.at/wien

Nothing better than a long bike ride to celebrate the return of the sun after many weeks with gray skies. 🌞🚴‍♀️ #cycling #vienna #tulln #wienerwald

Eine tolle Veranstaltung! Vielen Dank, @fwf-at.bsky.social

Today is the 👩‍🔬International Day of Women and Girls in Science🔬 This UN-established day promotes gender equality in science fields. Many of the scientists from our Faculty have joined to give a clear message to all interested girls and young women: ⚛JOIN TEAM SCIENCE!👩🏽‍💻 🔗 a29.at/Q50Zsl

I honestly had thought that pedophilia was a rare disorder and not something that an entire class of rich people liked to pursue and email each other about it from work accounts.

Traveling for work again, from #Vienna to #Duisburg. This time to the University Duisburg-Essen for a seminar talk. By #train, of course.

Danube is still partly frozen, but the streets are clear of ice after this week's rain and above-zero temperatures. #Cycling is good again in #Vienna 🚴‍♀️

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free
