NASA’s Webb Telescope reveals massive galaxy merger around ‘monster’ black hole
Now that we have a powerful lens always pointed towards the deepest regions of the universe, our definition of “surprise” has changed slightly when it comes to astronomy photos. It’s no longer…
Researchers combine two NMR-based methods to understand the process of photopolymerization
Graphic abstract. Credit: Journal of the American Chemical Society (2022). DOI: 10.1021/jacs.2c05944 To design new materials, scientists must have a clear understanding of the chemical reactions or processes that occur when creating…
How do we know that distant planets look like Earth?

Burning ‘super-Earth’ hot enough to melt gold may have lost its atmosphere
Astronomers have discovered a rocky Earth-sized world, or “super-Earth”, that is hot enough to melt gold and, therefore, may not have an atmosphere. By comparing these super-Earths to our planet, scientists can…
The UK had at least two genetically distinct human groups at the end of the last ice age, DNA reveals
Britain was home to at least two genetically distinct groups of humans at the end of the last Ice Age, the UK’s oldest human DNA has revealed. Around 19,000 years ago the…
Student uses NASA data to reveal new details about planets in other solar systems
Jared Siegel, an undergraduate student at UChicago, spent six months finding a way to uncover new information from data extracted by NASA’s Kepler space telescope, which searched for planets around distant stars….
One step closer to understanding why some lizards are immune to black widow spider venom
Whole animal (sprint) performance in response to control (saline injection), low (1LD50) or high (5LD50) treatments of western black widow spider (Latrodectus hesperus) venom. Changes in sprint speed quantified as difference in…
Newly Discovered Optical Effect Allows IceCube Neutrino Observatory to Infer Properties of Ice Crystals
Illustration visualizing the newly discovered optical effect: without birefringence (top), light flows radially from an isotropic light source. With birefringence (bottom), light is slowly bent towards the axis of the ice flow….
