We summarize the week's scientific breakthroughs every Thursday.
- Climate
Next icy era may be on hold
Carbon emissions from humans may have postponed Earth’s next glaciation, new research suggests.
- Environment
Rising dolphin deaths linked to Deepwater Horizon spill
Lung lesions and other injuries link an extensive die-off of dolphins in the Gulf of Mexico to the 2010 Deepwater Horizon oil spill.
- Climate
Tranquil ecosystems may explain wild swings in carbon dioxide stashing
Semiarid ecosystems, such as grasslands and shrublands, are behind the large variation in the amount of atmospheric carbon dioxide sucked in by land each year.
- Climate
Once-stable Antarctic glaciers are now melting rapidly
A group of glaciers in Antarctica that were once stable started rapidly melting in 2009, new research shows.
- Animals
Rising temperatures may cause problems for cold-blooded critters
Ectotherms cannot easily handle extreme temperatures, a new study finds.
- Environment
E-cigarette flavorings may harm lungs
Certain e-cigarette flavors, such as banana pudding, may damage lung tissue
- Earth
Asteroids boiled young Earth’s oceans, remnant rocks suggest
Giant asteroid impacts may have boiled Earth’s oceans around 3.3 billion years ago, snuffing out near-surface life.
- Oceans
Mysterious form of phosphorus explained
Mysterious form of phosphorus may be used as shadow currency by marine microbes, potentially upending scientists’ understanding of nutrient exchanges.
- Animals
An island in the Maldives is made of parrotfish poop
Coral-eating parrotfish create much of the sediment that a reef island is made of, a new study finds.
- Earth
Another strong quake strikes Nepal
A magnitude 7.3 earthquake hit eastern Nepal on May 12, just 17 days after one that killed more than 8,000 people in the region.
- Climate
Flood planners should not forget beavers
Beaver dams can reduce flooding downstream, new research shows.
- Microbes
Pig farm workers at greater risk for drug-resistant staph
Pig farm workers are six times as likely to carry multidrug-resistant staph than workers who have no contact with pigs.
