Why do particle physicists like spending time in fields?

Technion researchers have developed, for the first time, a comprehensive physical model explaining how the properties of a radiating material, including absorption, emission, and quantum efficiency, affect the fundamental characteristics of the light it emits as a function of temperature. In essence, the emitted light changes its color, intensity, and randomness according to the material's properties and its temperature. The discovery was published in Optica and opens new possibilities for desig

Scientists have discovered that they can eavesdrop on the secret lives of birds using networks of inexpensive microphones, revealing complex behaviors across vast wilderness areas, according to research published in the journal Ecology. Previously, microphone technology that records sounds from wildlife had mostly been used to determine if a species was present in an area. Recordings could tell researchers what birds were present, but not what the birds were doing.

Different receptors respond to different neurotransmitters or hormones, such as adrenaline involved in the fight-or-flight response, or dopamine linked to reward and motivation. Both the receptors themselves and the substances they recognize are often very similar, but still make the body react in completely different ways.

If you've ever taken an introductory astronomy class, you've probably seen the Hertzsprung-Russell (HR) diagram. This graph maps out the life cycle of stars by plotting their temperature against their luminosity, and has been a "cheat sheet" for stellar astrophysics for over a century. But the universe is full of more than just stars, and a new paper in the journal Publications of the Astronomical Society of the Pacific by Gabriel Steward and Matthew Hedman of the University of Idaho, attempts t
