A world-first photonic time crystal can reshape light almost instantly, opening a path toward ultrafast optical technology. An international research team has created the first experimentally demonstrated all-optical photonic time crystal (PTC), a material whose optical behavior can be altered strongly and repeatedly over extremely short periods of time. The work, carried out by scientists […]

Meteorite That Smashed Through a New Jersey Roof Hid an Ancient Chemical Secret
A meteorite that blasted through a New Jersey roof carried a startling secret: evidence of ancient salty fluids and complex organic chemistry inside a primitive asteroid. A space rock that tore through a New Jersey roof has turned out to be far more than an astronomical curiosity. Sealed inside were traces of ancient salty fluids […]
Astronomers Find Ancient Black Holes Shining With the Power of a Trillion Suns
Euclid’s expanding quasar census is revealing how enormous black holes emerged during the Universe’s infancy. More than 13 billion years ago, two brilliant objects blazed from galaxies that had barely begun to take shape. Their light, produced when the Universe was only 670 million years old, has now reached the European Space Agency’s Euclid space […]
These “Good” Immune Cells Could Hold the Key to Spinal Cord Regeneration
An Il-4 signal from neutrophils helps zebrafish control inflammation and regenerate damaged spinal cords. A damaged human spinal cord rarely repairs itself. The immune response that follows an injury can become excessive, producing lasting scar tissue that prevents nerve cells and their connections from growing back. Zebrafish respond very differently, controlling inflammation well enough to […]

Researchers Solve Mystery Behind Contradictory Weight-Loss Drug Paradox
Opposite actions on the same receptor can promote weight loss by targeting different brain circuits. Two obesity drugs can push the same brain receptor in opposite directions and still lead to weight loss. Researchers at the University of Cambridge have now traced that apparent contradiction to two separate regions of the brain. The mouse study, […]
