Astronomers frequently observe carbon monoxide in planetary nurseries. The compound is ultrabright and extremely common in protoplanetary disks—regions of dust and gas where planets form around young stars—making it a prime target for scientists.

But for the last decade or so, something hasn’t been adding up when it comes to carbon monoxide observations, says Diana Powell, a NASA Hubble Fellow at the Center for Astrophysics, Harvard & Smithsonian. A huge chunk of carbon monoxide is missing in all observations of disks, if astronomers’ current predictions of its abundance are correct.

Now, a new model—validated by observations with ALMA—has solved the mystery: carbon monoxide has been hiding in ice format...

When fat accumulates in the liver, the immune system may assault the organ. A new study from Weill Cornell Medicine researchers identifies the molecule that trips these defenses, a discovery that helps to explain the dynamics underlying liver damage that can accompany type 2 diabetes and obesity.

In a study published Aug. 19 in Science Immunology, researchers mimicked these human metabolic diseases by genetically altering mice or feeding them a high-fat, high-sugar diet. They then examined changes within the arm of the rodent’s immune system that mounts defenses tailored to specific threats...

Capacitors are energy storage devices—consisting of two electrodes and an electrolyte—that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface...
