We summarize the week's scientific breakthroughs every Thursday.
- 			 Environment EnvironmentFlower shape and size impact bees’ chances of catching gut parasitesBumblebees have higher chances of contracting a gut parasite from short, wide flowers than from blooms with other shapes, experiments show. 
- 			 Environment EnvironmentHow to build better ice towers for drinking water and irrigation“Ice stupas” emerged in 2014 as a way to cope with climate change shrinking glaciers. Automation could help improve the cones’ construction. By Nikk Ogasa
- 			 Earth Earth50 years ago, a new theory of Earth’s core began solidifyingIn 1972, scientists proposed that Earth’s core formed as the planet came together. Fifty years later, that theory is generally accepted, though many mysteries about the core remain. By Nikk Ogasa
- 			 Paleontology PaleontologyMegatooth sharks may have been higher on the food chain than any ocean animal everSome megalodons and their ancestors were the ultimate apex predators, outeating all known marine animals, researchers report. By Asa Stahl
- 			 Environment EnvironmentEarth’s oldest known wildfires raged 430 million years ago430-million-year-old fossilized charcoal suggests atmospheric oxygen levels of at least 16 percent, the amount needed for fire to take hold and spread. By Sid Perkins
- 			 Science & Society Science & SocietyRussia’s invasion could cause long-term harm to Ukraine’s prized soilWar will physically and chemically damage Ukraine’s prized, highly fertile chernozem soils. The impacts on agriculture could last for years. 
- 			 Health & Medicine Health & MedicineWestern wildfires’ health risks extend across the countryAs western wildfires become more common, hazardous smoke is sending people — especially children — to emergency rooms on the East Coast. By Megan Sever
- 			 Climate ClimateAncient penguin bones reveal unprecedented shrinkage in key Antarctic glaciersThwaites and Pine Island glaciers are losing ice faster than any other time in the last 5,500 years. That history is written in bones and shells. By Douglas Fox
- 			 Earth EarthAncient zircons offer insights into earthquakes of the pastAnalyzing zircons’ chemical makeup can help expose intense quakes from the past and improve our understanding of the physics of today’s tremors. By Nikk Ogasa
- 			 Science & Society Science & SocietyGrowing wildfire threats loom over the birthplace of the atomic bombClimate change is expected to make wildfires worse across much of the Southwest United States. A key nuclear weapons lab could be in the hot zone. 
- 			 Ecosystems EcosystemsJust 3 ingredients can quickly destroy widely used PFAS ‘forever chemicals’Ultraviolet light, sulfite and iodide break down enduring PFAS molecules faster and more thoroughly than other UV-based methods. By Nikk Ogasa
- 			 Climate ClimateScientists hope to mimic the most extreme hurricane conditionsA $12.8 million NSF grant is funding the design of a facility that can generate winds of at least 290 kilometers per hour and towering storm surges.
