Scientists have uncovered a potential nutritional link to chronic fatigue. Healthy adults with signs of vitamin B12 and folate deficiencies were more likely to experience fatigue or lower motivation. Chronic fatigue has become a common part of modern life. Many people struggle with long work hours, packed schedules, and persistent exhaustion that never seems to [...]

Scientists caught a famous “sandwich” molecule in a rare hidden state, uncovering a long-missing step in its formation. For more than 70 years, metallocenes have been among the most important molecules in organometallic chemistry. These compounds feature a metal atom positioned between two carbon-based rings, creating a structure often described as a molecular sandwich. They [...]

A new prototype takes mass spectrometry from analyzing a few molecules at a time to handling billions at once. Mass spectrometry is already a cornerstone technology for identifying what molecules are present in a sample and how much of each is there. However, most current instruments still examine molecules one at a time or in [...]

Researchers relied on a newer gene-editing technique that may make it possible to engineer embryos, a prospect that has long alarmed bioethicists.
