Phys.org / 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 ...

Phys.org / Physicists create new family of Schrödinger-cat states

Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger's cat, imagined as being both alive and dead until it is observed. ...

Phys.org / 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 ...

Phys.org / 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, ...
