We summarize the week's scientific breakthroughs every Thursday.
- 			 Climate ClimateSatellite space junk might wreak havoc on the stratosphereHundreds of defunct satellites plunge toward Earth every year. Scientists are studying how the chemical stew left in their wake impacts the atmosphere. 
- 			 Climate ClimateClimate change has amped up hurricane wind speeds by 29 kph on averageEvery single Atlantic hurricane in 2024 had wind speeds supercharged by warming seas. One even jumped two categories of intensity. By Nikk Ogasa
- 			 Oceans OceansThe world’s largest coral was discovered in the South PacificThe behemoth coral, discovered in October in the Solomon Islands, is longer than a blue whale and older than the United States. By Nikk Ogasa
- 			 Health & Medicine Health & Medicine22 pesticides show links to prostate cancerThe new finding comes from an analysis of pesticide use and prostate cancer incidence in over 3,100 U.S. counties. 
- 			 Environment EnvironmentFire-prone neighborhoods on the fringes of nature are rapidly expandingThe transition zone where unoccupied wildlands meet developed areas increased globally by about 35 percent from 2000 to 2020. By Nikk Ogasa
- 			 Climate ClimateMeet Chonkus, the mutant cyanobacteria that could help sink climate changeThe mutant of the lab-studied Synechococcus elongatus has traits good for ocean carbon storage. 
- 			 Agriculture AgricultureExploiting a genetic quirk in potatoes may cut fertilizer needsA gene controlling potato growth limits the plant’s fertilizer uptake. Tweaking related genes could lead to more sustainable potato varieties. 
- 			 Animals AnimalsThis marine biologist discovered a unique blue whale population in Sri LankaIn addition to studying the world’s only nonmigratory blue whales, marine biologist Asha de Vos seeks to change her compatriots’ attitudes toward the ocean. By Sandy Ong
- 			 Climate ClimateFans may not keep older adults cool during heat wavesOlder adults are at higher risk of suffering health consequences during heat waves. Fans may not do enough to prevent that. 
- 			 Agriculture AgricultureMegafire smoke may dampen California’s nut harvestsThe summer after wildfire smoke blocked sunlight for long stretches, harvests at some almond tree orchards in California’s Central Valley dropped. 
- 			 Environment EnvironmentAn idea to save Mexico’s oyamel forests could help monarch butterflies tooClimate change is putting monarch butterflies’ overwintering forests in Mexico at risk. Could planting new forests solve that problem? 
- 			 Oceans OceansHow tiny phytoplankton trek long distances upward in the oceanTaking in seawater while filtering out dense salts lets unicellular phytoplankton migrate tens of meters vertically toward sunnier seas.
