New research suggests that the sugar ribose - the "R" in RNA - is probably found in comets and asteroids that zip through the solar system and may be more abundant throughout the universe than was previously thought.

The ice buried inside comet 67P/ Churyumov-Gerasimenko is mainly found in crystalline form, which implies that it originated in the protosolar nebula and is therefore the same age as the Solar System. This discovery was made ...

The space between stars is not empty, but contains an abundance of diffuse material, about 5-10% of the total mass of our galaxy (excluding dark matter). Most of the material is gas, predominantly hydrogen, but with a small ...

(Phys.org)—As long as the temperature is above absolute zero, gas molecules are always in constant random motion. They may diffuse—or spread out—through three-dimensional space or, in a process called "surface diffusion," ...
Myoglobin, a protein in muscle tissue that stores oxygen, is what gives meat its red pigment. What is less well-known is that in 1957, it became the first protein molecule whose structure was fully mapped in 3-D. That breakthrough ...
