Gas giant composition not determined by host star

A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according ...

Who controls whom: Algae or sea anemone?

Bleached anemones—those lacking symbiotic algae—do not move toward light, a behavior exhibited by healthy, symbiotic anemones. Published in Coral Reefs, this finding from Carnegie's Shawna Foo, Arthur Grossman, and Ken ...

Lakes worldwide are experiencing more severe algal blooms

The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes, which was conducted by Carnegie's Jeff Ho and Anna Michalak and ...

Many gas giant exoplanets waiting to be discovered

There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA's WFIRST space telescope, according to new models of gas giant planet formation ...

Would a carbon tax help to innovate more-efficient energy use?

Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in Joule from Carnegie's Rong Wang (now at Fudan University), Harry Saunders, and Ken Caldeira, along ...

Geoengineering versus a volcano

Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new ...

Do plant cells hold the roadmap for surviving climate change?

Do plant scientists hold the key to saving vulnerable populations in a changing climate? How should plant researchers prepare to deploy their knowledge to maintain food security in the future—as well as to promote renewable ...
