Climate Change From Nuclear War's Smoke Could Threaten Global Food Supplies, Human Health 
Nuclear war would cause many immediate fatalities, but smoke from the resulting fires would also cause climate change lasting up to 15 years that threatens worldwide food production and human health, according to a study by researchers at Rutgers University, the National Center for Atmospheric Research and other institutions.

Efficient Formation Pathway Of Methyl Formate: The Role Of OH Radicals On Ice Dust
Three structural isomers of the C2H4O2 molecule, namely, methyl formate (MF; HCOOCH3), acetic acid (AA; CH3COOH), and glycol aldehyde (GA; HOCH2CHO), have attracted considerable attention as targets for understanding pathways towards molecular complexity in the interstellar medium (ISM).

Retention Of Water In Terrestrial Magma Oceans And Carbon-rich Early Atmospheres
Massive steam and CO2 atmospheres have been proposed for magma ocean outgassing of Earth and terrestrial planets.

Discovery Of Two Isomers Of Ethynyl Cyclopentadiene In TMC-1: Abundances of CCH And CN Derivatives Of Hydrocarbon Cycles
We report the detection of two isomers of ethynyl cyclopentadiene (c-C5H5CCH), namely 1- and 2-ethynyl-1,3-cyclopentadiene, in the direction of TMC-1.

Formation Of Complex Organic Molecules In Hot Molecular Cores Through Nondiffusive Grain-surface And ice-mantle Chemistry
A new, more comprehensive model of gas-grain chemistry in hot molecular cores is presented, in which nondiffusive reaction processes on dust-grain surfaces and in ice mantles are implemented alongside traditional diffusive surface/bulk-ice chemistry.

Traces of Ceres' Icy Crust Found at Occator Crater
Anomalies in the distribution of hydrogen at Occator crater on the dwarf planet Ceres reveal an icy crust, says a new paper led by Tom Prettyman, a Senior Scientist at the Planetary Science Institute.

Titan's River Maps May Advise Dragonfly's Sedimental Journey
With future space exploration in mind, a Cornell-led team of astronomers has published the final maps of Titan's liquid methane rivers and tributaries - as seen by NASA's late Cassini mission - so that may help provide context for Dragonfly's upcoming 2030s expedition.

The Fine-Tuning of the Universe for Life
When a physicist says that a theory is fine-tuned, they mean that it must make a suspiciously precise assumption in order to explain a certain observation.
