Satellites reveal cities' 'urban pulse,' tracking neighborhood growth in near real time
For over a century, doctors have used electrocardiograms (EKGs) to render the invisible electrical activity of the human heart visible, using the pulse to diagnose disease before it becomes fatal. Now, scientists have invented a way to do the exact same thing for the places
Upcoming telescopes could shed light on dark matter
NASA's plans to return astronauts to the moon through the Artemis program and ultimately send humans to Mars highlight just how far space exploration has come. Yet while the moon and Mars remain compelling destinations filled with scientific mysteries, looking beyond our solar
Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on the time scale considered.
Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that form highly complex three-dimensional structures. Because

Hidden geometry explains why kernel methods separate complex data so well
Are two sets of data genuinely different, or is it because of randomness? This question, known as the two-sample testing problem, becomes notoriously difficult in modern datasets, because they are often high-dimensional, complex, and differences between them can take countless
Study reveals north–south differences in water isotopes across North America during the last deglaciation
The last deglaciation (between 11,000 and 20,000 years ago) was a period of dramatic natural warming on Earth. During this time, North America experienced the most extensive ice-sheet melting on the planet, which profoundly reshaped its climate and water cycle. But when

What happens to a star that captures a primordial black hole?
We don't know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were created by the direct collapse of densely packed subatomic matter. Theorists

'Labubu economics': Game-theoretic model explains why blind box strategies benefit suppliers, retailers, and consumers
The billion-dollar Labubu phenomenon broke a cardinal rule of retail: Consumers need to know what they're buying before they open their wallet. Most new Labubu sales took the form of "blind boxes," where purchasers found out which type of doll they'd purchased only after the
Ancient hominins selected basalt sources for specific tools nearly 800,000 years ago, study reveals
A new study finds that ancient hominins nearly 800,000 years ago deliberately selected specific basalt sources for different stages of tool production rather than simply using whatever stone was available nearby. By tracing the geochemical "fingerprints" of stone tools to both
