This massive crater could expose the heart of a lost planet

A mysterious metal-rich asteroid called Psyche has been baffling scientists for over two centuries, and its true origin remains one of the biggest unanswered questions in planetary science. Is it the exposed core of a failed planet, or a chaotic mix of rock and metal forged through countless violent collisions? To find out, researchers simulated how a massive crater near Psyche’s north pole formed, revealing that the asteroid’s internal “porosity” — how much empty space it contains — may hold the key to its secrets.

ADHD brains show sleep-like activity even while awake

Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of “sleep-like” activity during demanding tasks. These moments are linked to more mistakes, slower reaction times, and lapses in attention.

Fixing a tooth infection may improve blood sugar and heart health

A new clinical study suggests that successful root canal treatment may benefit more than just dental health. Patients treated for infected teeth showed improved blood sugar control, healthier cholesterol levels, and reduced inflammation over time. The infection can allow bacteria to enter the bloodstream, potentially affecting metabolism and heart health. Clearing the infection appears to help reverse some of these harmful effects.
