Safe and ethical ways to edit the human genome

The National Academies of Science and Medicine (NASEM) released a report on Feb. 14 exploring the implications of new technologies that can alter the genome of living organisms, including humans.

Materials that emit rainbows

Mechanochromic luminescent (MCL) materials change their color in response to a change in their environment, like pressure and temperature. To date, most MCL materials only change between two colors, limiting their applications. ...

Image: The evolution of supernova 1987A

Thirty years ago, on 23 February 1987, the light from a stellar explosion marking the death of a massive star arrived at Earth to shine in Southern Hemisphere skies.

Constraining the chemistry of carbon-chain molecules in space

The interstellar medium of the Milky Way contains 5-10% of the total mass of the galaxy (excluding its dark matter) and consists primarily of hydrogen gas. There are small but important contributions from other gases as well, ...

More efficient production for photoluminescent chemical compounds

Chemical compounds that emit light are used in a variety of different materials, from glow-in-the-dark children's toys to LED lights to light-emitting sensors. As the demand for these compounds increases, finding new efficient ...

Hubble cooperates on galaxy cluster and cosmic background

The events surrounding the Big Bang were so cataclysmic that they left an indelible imprint on the fabric of the cosmos. We can detect these scars today by observing the oldest light in the universe. As it was created nearly ...
