Narcan appears to work almost miraculously, reversing an opioid overdose in minutes. But exactly how it does this was a mystery since the FDA approved it in 1971. Until now. Biology researchers have captured the mechanism at the molecular level.

How does Narcan work? Mapping how it reverses opioid overdose can provide a molecular blueprint for more effective drugs
Naloxone can reverse an overdose in minutes, but exactly how it does this at the molecular level has previously been unclear.
Scientific journals are more likely to publish studies that found something rather than those that found nothing. A statistician explains how knowing this can help you interpret what you read about research.

Absence of evidence is not evidence of absence – and that affects what scientific journals choose to publish
Researchers design studies that might disprove what’s called their null hypothesis – the opposite of the claim they’re interested in exploring.
The 1-year-old Israeli-Lebanese ceasefire looks increasingly fragile. A historian examines whether the two countries are headed back into their cycle of violence.

A year on, the Israeli-Lebanese ceasefire looks increasingly fragile − could a return to cyclical violence come next?
Since the start of the truce on Nov. 27, 2024, there have been thousands of Israeli violations inside Lebanese territory, while Hezbollah has yet t...
How Easter Island's giant statues were transported remained unsolved for decades. Physics, morphological analysis and a comprehensive 3D map now show the moai, or statues, were "walked" upright across the landscape using principles of lateral oscillation.

Drones, physics and rats: Studies show how the people of Rapa Nui made and moved the giant statues – and what caused the island’s deforestation
The mysteries of Easter Island, subjects of speculation for centuries, yield to scientific inquiry.
The US military is building up forces near Venezuela, giving the Trump administration many military options if it chooses to go beyond sinking boats offshore. A Latin American research professor at the US Army War College has details on the armada:

Antarctica’s melt affects everybody but won’t hit every coastline the same. New maps show where seas could rise the fastest, and why millions of coastal residents should pay attention now 🌊
The Conversation
Sea level doesn’t rise at the same rate everywhere – we mapped where Antarctica’s ice melt would have the biggest impact
Understanding what happens to Antarctica’s ice matters, because as it melts, sea levels rise, affecting lives and economies around the world.
Why aren’t there square trees or mammals with wheels? A new study of fern stems shows how linked traits — developmental constraints — shape the limits and possibilities of evolution.

Fern stems reveal secrets of evolution – how constraints in development can lead to new forms
Is an organism a sum of its parts, or should they be considered as a whole? New research on ferns shows how the way scientists understand evolution...
A study of 42 Head Start centers reveals widespread mistreatment among early child care staff, driving stress, depression and burnout. And that’s especially troubling because kids thrive when the people caring for them are supported and healthy.

A quarter of early child care educators in Colorado reported mistreatment from co-workers
Younger and more diverse teachers reported higher rates of bullying and discrimination by their colleagues. This can also affect the kids they care...
Cities are building “digital twins” to map roads, buildings and utilities — but most still overlook the people who use them. A new study shows how faked synthetic data can add realistic human behavior to these models while protecting #privacy.

From concrete to community: How synthetic data can make urban digital twins more humane
Urban digital twins pull together tremendous amounts of data to realistically model cities, but they’ve been missing a critical ingredient: people.
