Explosive evaporation unlocks new possibilities in 3D printing and chemical analysis‎

Water droplets might seem simple at first. But when nearing evaporation, a desperate power struggle of competing physical forces can emerge, with explosive effects. In a Proceedings of the National Academy of Sciences publication, researchers have taken a closer look at the physics of charged water droplets on frictionless surfaces, observing spontaneous jets of microdroplet emissions. Their insights may open new opportunities in nanoscale fabrication and electrospray ionization.

Sentinel-1D goes live: A milestone for Europe's radar mission‎

The Copernicus Sentinel-1D satellite, launched last November, is now fully operational after successfully completing its critical in-orbit commissioning phase. With all four Sentinel-1 satellites having now been deployed, this achievement marks a major milestone for this flagship radar mission—a journey that began more than a decade ago and that has helped pave the way for the future of Earth observation.

AI tackles one of math's most brutal problems: Inverse PDEs‎

Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for understanding the natural world.

'A study showed…' isn't enough—scientific knowledge builds incrementally as researchers revisit questions‎

Your goofy but lovable cousin just told you that you should stop eating eggs because he read somewhere that a study showed they are bad for you. How much should you trust your relative on such matters? More importantly, how much should you rely on one newly published bit of research when deciding what to make for breakfast?

Long-term study of COVID lockdown and family life shows unexpected, lasting effects on fatherhood‎

In the years following the COVID-19 pandemic, much has been said about how the lockdowns created conditions for dual-parent families to spend more time at home with their children. In an ideal vision of family life, this would have led to parents sharing in quality time and caregiving responsibilities, and bonding with their children in a way they hadn't been able to do before.

Sramcbled wrods: The real reason you can still read jumbled text‎

You've probably seen it on social media before: a paragraph of scrambled text that looks like nonsense at first glance, yet somehow you can read it with surprising ease.

Should politics influence science, and vice versa? National Science Board's ousting resurrects an existential debate‎

"On behalf of President Donald J. Trump," read 22 emails sent from the White House Presidential Personnel Office on Friday afternoon, April 24, 2026, "I am writing to inform you that your position as a member of the National Science Board is terminated, effective immediately."

When the Schuylkill swallowed the city: Lessons from Hurricane Ida's historic flood‎

New Penn research shows that Hurricane Ida wasn't a once-in-a-century anomaly but a preview of how climate change, urbanization, and aging infrastructure are rewriting flood risk.

After flames strip hillsides bare, the next storm can unleash something far more destructive downstream‎

Wildfires can increase flooding risks in and downstream of burned areas by removing vegetation and disturbing hydrologic processes. As the climate changes, the severity of both wildfires and heavy rainfall events is increasing, meaning flooding is likely to become more severe in the near future. Better understanding how, and by how much, wildfires change flood risk is important for disaster and infrastructure planning for communities around the country.

How to talk to children when terrorist attacks and violence dominate the news‎

When a man stabbed Jewish people in Golders Green, London, in what police declared a terrorist incident, the story spread fast—through news alerts, social media and the whispered conversations of anxious adults. When this happens, children notice.
