A record-sized sturgeon catch and a new study on comets both made headlines, with no major winners or losers here beyond fish and science nerds.

• An angler landed an 11-foot, roughly 1,200-pound white sturgeon on Canada's Fraser River, among the largest freshwater fish ever caught by a woman.
• The fish was tagged and released unharmed so it can keep growing.
• Separately, British researchers ran about 100,000 computer simulations to test whether comets could have delivered the building blocks of life to early Earth.
• Most comets hit too fast for those molecules to survive impact, but the study says delivery was still possible under specific conditions, including the presence of liquid water.

Outlook: The sturgeon's tag may help trackers learn more about the river's giant fish population, while the comet study leaves the origin-of-life question open for more research.
