World's first fluorescent frog that glows bright green is found in Argentina Under normal light the polka-dot tree frog is a dull green/brown colour But scie...
Marijuana Breathalyzer Test Could Be Coming Soon
A new invention may soon make it easier for police who pull over risky drivers to test them for marijuana impairment on the spot, in addition to the usual alcohol breath test. A marijuana breathalyzer...
Affordable Camera Reveals Hidden Details Invisible To The Naked Eye
Peering into a grocery store bin, it’s hard to tell if a peach or tomato or avocado is starting to go bad underneath its skin. But an affordable camera technology being developed by the University of ...
Scientists In Antarctica Drink A Lot. Maybe Too Much
WORKING IN ANTARCTICA can be one of the most exhilarating jobs on Earth. Or one of the most depressing. Owing to distance and the difficulty of getting onto and off of the continent, most people who g...
Buckyballs In Space Solve 100-Year-Old Riddle :
Spheres of carbon-60 responsible for mysterious cosmic-light features. In 1919, Mary Lea Heger, a graduate student at the University of California’s Lick Observatory on Mount Hamilton, saw that partic...
Surfing A Wake Of Light
For the first time, Harvard researchers have created wakes of light-like waves moving on a metallic surface, called surface plasmons, and demonstrated that they can be controlled and steered. The cre...
Why Some Mushrooms Glow In The Dark
A team of scientists recently created some fake, glowing mushrooms and scattered them in a Brazilian forest in hopes of solving an ancient mystery: Why do some fungi emit light? The question goes back...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and ot...
Chromism
In chemistry, chromism is a process that induces a change, often reversible, in the colors of compounds. In most cases, chromism is based on a change in the electron states of molecules, especially th...
Diffraction
Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. In classical physics, the diffraction phenomenon is described as the interference of waves according t...
Emission spectrum
The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted due to an atom or molecule making a transition from a high energy s...
Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength,...
Infrared spectroscopy
Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible...
Molecular vibration
A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is kno...
Nuclear magnetic resonance
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a magnetic field absorb and re-emit electromagnetic radiation. This energy is at a specific resonance frequency which depen...
Raman spectroscopy
Raman spectroscopy (/ˈrɑːmən/; named after Sir C. V. Raman) is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. Raman spectroscopy is comm...
Spectrometer
In physics, a spectrometer is an apparatus to measure a spectrum. Generally, a spectrum is a graph that shows intensity (physics) as a function of wavelength, of frequency, of energy, of momentum, or...
