A colossal "cosmic volcano" has erupted in deep space, as a supermassive black hole in galaxy J1007+3540 roars back to life after nearly 100 million years of silence. Astronomers captured stunning radio images showing fresh jets blasting outward ...

Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts--two major environmental threats on the Red Planet. Their secret weapon was forming ...

A major international effort has produced an ultra-precise measurement of the Universe's expansion rate, confirming it's faster than early-Universe models predict. By linking multiple distance-measuring techniques, scientists ruled out simple errors ...

Scientists have proposed a surprising new way to detect gravitational waves--by observing how they change the light emitted by atoms. These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature. The ...

A strange new kind of superconductivity has been uncovered in uranium ditelluride (UTe2), where electricity flows with zero resistance--but only under extremely strong magnetic fields that should normally destroy it. Even more surprising, the ...

Perovskite solar cells shouldn't work as well as they do--but they do. Scientists have now discovered that defects inside the material actually help, creating networks that separate and guide electric charges efficiently. Using a novel imaging method ...

A new chip design from UC San Diego could make data centers far more energy-efficient by rethinking how power is converted for GPUs. By combining vibrating piezoelectric components with a clever circuit layout, the system overcomes limitations of ...

A mysterious glow of gamma rays at the center of the Milky Way has long hinted at dark matter, but the lack of similar signals in smaller dwarf galaxies has cast doubt on that idea. Now, researchers propose a bold twist: dark matter might not be a .. ...

Earth's nights are steadily getting brighter overall, but the changes vary dramatically by region. Rapid urban growth is lighting up countries like China and India, while parts of Europe are dimming due to energy-saving efforts and new lighting ...

For all its ancient, familiar features, the Moon is still changing--and sometimes in dramatic ways. Scientists recently identified a fresh 22-meter-wide crater by comparing orbital images taken years apart, revealing a relatively recent impact that . ...
