Brain temperature can now be measured using light

Light could replace invasive techniques to measure brain temperature– eliminating the need to place a thermometer in the brain when treating a range of neurological disorders.

Quasi-periodic variability observed in two blazars

An international team of astronomers reports the detection of quasi-periodic variability in optical and gamma-ray light curves of two blazars, namely 3C 66A and B2 1633+38. The discovery could be helpful in advancing our ...

Image: Hubble eyes an emitting galaxy

For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749.

Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

Quantum light improves sensitivity of biological measurements

In a new study, researchers showed that quantum light can be used to track enzyme reactions in real time. The work brings together quantum physics and biology in an important step toward the development of quantum sensors ...

Chemists use light to build biologically active compounds

Some of the most biologically active molecules, including synthetic drugs, contain a central, nitrogen-containing chemical structure called an isoquinuclidine. This core has a three-dimensional shape which means it has the ...
