Caltech scientists have developed a method that detects tiny, imperceptible movements at the surface of objects to reveal details about what lies beneath. By analyzing the physics of waves traveling ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Quantum mechanical effects are known to be easily disrupted by disturbances from the surrounding environment, commonly referred to as noise. To minimize these disturbances, physicists often study ...

Inexpensive and convenient devices such as silicone wristbands can be used to yield quantitative air quality data, which is particularly appealing for periods of susceptibility such as pregnancy. A ...

In recent years, we observed significant shifts in how obesity and cardiometabolic diseases are studied in early-phase research. Science is advancing, but the complexity of working with this patient ...

Preserved lemons are lemons (usually whole, split, or quartered) packed in salt and brined in their own or additional lemon juice—essentially, they’re pickled lemons. Especially common in Middle ...
