We summarize the week's scientific breakthroughs every Thursday.
- Animals
This marine biologist discovered a unique blue whale population in Sri Lanka
In addition to studying the world’s only nonmigratory blue whales, marine biologist Asha de Vos seeks to change her compatriots’ attitudes toward the ocean.
- Climate
Fans may not keep older adults cool during heat waves
Older adults are at higher risk of suffering health consequences during heat waves. Fans may not do enough to prevent that.
- Agriculture
Megafire smoke may dampen California’s nut harvests
The summer after wildfire smoke blocked sunlight for long stretches, harvests at some almond tree orchards in California’s Central Valley dropped.
- Environment
An idea to save Mexico’s oyamel forests could help monarch butterflies too
Climate change is putting monarch butterflies’ overwintering forests in Mexico at risk. Could planting new forests solve that problem?
- Oceans
How tiny phytoplankton trek long distances upward in the ocean
Taking in seawater while filtering out dense salts lets unicellular phytoplankton migrate tens of meters vertically toward sunnier seas.
- Science & Society
There’s a new term for attempting to own the wind: ventography
Nations established territorial claims underground to access oil and gas. Now they are expanding those claims upward to snag the wind.
- Earth
What leads rivers to suddenly change course?
An analysis of satellite data could help predict where rivers will change their course and where their rerouted flows will go.
- Climate
Climate change fueled the fury of hurricanes Helene and Milton
Two new studies find climate change amped up sea surface temperatures in the Gulf of Mexico, fueling the hurricanes' intensity.
- Oceans
A transatlantic flight may turn Saharan dust into a key ocean nutrient
Over time, atmospheric chemical reactions can make iron in dust from the Sahara easier for organisms to take in, helping to create biodiversity hot spots.
- Animals
Some tadpoles don’t poop for weeks. That keeps their pools clean
Eiffinger’s tree frog babies store their solid waste in an intestinal pouch, releasing less ammonia into their watery cribs than other frog species.
- Physics
Thunderstorms churn up a ‘boiling pot’ of gamma rays
A thunderstorm seen in gamma-ray vision is a complex, frenetic lightshow when viewed from above the clouds.
- Health & Medicine
A hurricane’s aftermath may spur up to 11,000 deaths
Hurricanes like Helene may indirectly cause deaths for years. Stress, pollution and a loss of infrastructure could all contribute to tropical cyclone fatalities.
