Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues ...

The essential amino acid leucine can boost cellular energy production by protecting key proteins on mitochondria from being destroyed. The discovery reveals a new connection between nutrition and metabolism that could eventually lead to new ...

Scientists have linked a gut bacterial compound called ImP to greater Alzheimer's risk, harmful brain protein buildup, and faster cognitive decline. The finding raises the possibility that reducing ImP in the blood could one day help slow or prevent ...

Researchers have demonstrated that quantum fluctuations in supposedly empty space can strengthen superconductivity, raising the transition temperature of an ultrathin material by as much as 5.4%. The discovery opens the possibility of using specially ...

NASA's Roman Space Telescope has demonstrated remarkable pointing stability and given its powerful planet-imaging coronagraph its first look at the cosmos. The telescope can already stay locked on a target with precision comparable to aiming a laser ...

Mysterious 97-million-year-old magnetic fossils may be the oldest evidence of an animal using Earth's magnetic field like a built-in GPS. Their sophisticated magnetic structure could have helped an unknown ocean creature navigate thousands of ...

JWST has revealed that galaxies were spreading carbon, oxygen, and other heavy elements through space just 500 million years after the Big Bang. The surprising discovery suggests the young universe became chemically enriched much earlier than ...

Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting materials and could open new ways to ...

High-risk MDS stem cells appear to have an unexpected "energy addiction," relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the cancer-driving cells, revealing a .. ...

Researchers say stress on Southern California's San Andreas and San Jacinto faults has reached some of the highest levels seen in a 1,000-year simulation. Because both faults are highly stressed at the same time, the Cajon Pass junction may be ...
