Migrating mosquitoes that carry diseases from the tropics to cooler climes might be better at spreading disease in their new, cooler home, according to a recent study in the Proceedings of the Royal Society B. Researchers from Yale University in … Continue reading

Journal Club: Aerosols, global warming may dampen cyclone activity in some regions
A recent study suggests that human activity may have decreased the number of tropical cyclones in the western North Pacific. A separate study predicts that the total number of intense tropical cyclones will decrease globally in the decades to come, … Continue reading
Journal Club: Wheat’s molecular response to full sun exposure could suggest ways to increase yield
A recent study points to novel ways of improving crop yields and food production by elucidating how long it takes for wheat to return to full photosynthesis when making the transition from shade to sun exposure. The Green Revolution in … Continue reading

Journal Club: Study of volcanic gases offers new fundamental insights into the Earth’s carbon cycle
To understand how the planet’s climate will evolve and has evolved over geologic time, scientists need to understand the Earth’s carbon cycle. In work recently published in Science, researchers offer new insights into that cycle, upending calculations about just how … Continue reading

Journal Club: Antarctic cyanobacteria show no changes due to warming—yet
Captain Robert Scott’s Antarctic Discovery expedition took place over 100 years ago—and yet its participants recently racked up another contribution to science. Thanks to the samples of bacterial mats they collected from polar ponds—samples that were pressed, dried, and stored … Continue reading
Journal Club: Geometry of Greenland’s glaciers helps predict future ice melt
The changing climate is just one factor contributing to the melting and thinning of the slow-moving rivers of ice that terminate in spots such as Greenland’s fjords. Each glacier’s geometry—including its thickness and how steeply it flows—also makes a difference. … Continue reading

Journal Club: In some cases, water management practices exacerbated California drought, according to model
Many of California’s reservoirs are now fuller than they’ve been in years thanks to an extraordinarily wet winter. Yet drought conditions are likely to return based on historical cycles, even without accounting for climate change. And California’s depleted groundwater is … Continue reading
Journal Club: Copper offers novel clues to ancient Earth’s “Great Oxidation Event”
Roughly 2.4 billion years ago, oxygen gas began suffusing Earth’s atmosphere in what scientists call the Great Oxidation Event. Much remains uncertain about this critical moment in history, but now researchers find that copper in ancient sediments could help track … Continue reading

Journal Club: Record-breaking galaxy offers insight into early universe
A new champion has been crowned in the hunt for the most distant, independently-confirmed galaxy ever observed. Called EGS8p7, the galaxy existed when the universe was a mere 570 million years old, beating the previous frontrunner by almost 100 million … Continue reading
Lowermost mantle more complex than previously thought
The region of earth’s interior known as the lower mantle may be more chemically heterogeneous than previously thought, suggests new research in PNAS Online Early Edition. The interior of the sphere we call home is a veritable layer cake of … Continue reading
