1. 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.

2. NASA’s Webb captures a bizarre brain-shaped nebula around a dying star

   The James Webb Space Telescope has revealed new details in a bizarre nebula that looks like a brain floating in space. Formed by a dying star, the “Exposed Cranium” nebula shows layered gas and a dark central divide that creates its eerie shape. Webb’s infrared view suggests powerful jets may be shaping the structure. The images capture a brief and dramatic phase in a star’s final evolution.

3. DNA origami vaccines could be the next leap beyond mRNA

   mRNA vaccines saved millions of lives during COVID-19 but have limitations like waning immunity and complex production. Scientists are now testing a new platform called DoriVac, which uses folded DNA nanostructures to better control how the immune system responds. In early studies, it produced strong antibody and T cell responses in both mice and human models. Researchers say it could lead to more stable, easier-to-manufacture vaccines for diseases like COVID-19, HIV, and Ebola.

4. 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.

5. 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.
