Journal Club: Single gene mutation may boost recombination and help produce better crops

Posted on December 7, 2018 by Jessica P. Johnson

As climate change and population growth threaten to destabilize global food security, plant breeders are ramping up efforts to create better, more productive crops. But in order to introduce new traits, breeding techniques typically rely on rare genetic recombination events … Continue reading →

Journal Club: Cooler temperatures might make some mosquitoes better dengue spreaders

Posted on October 20, 2017 by Amber Dance

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

Posted on October 6, 2017 by Charles Choi

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: Antarctic cyanobacteria show no changes due to warming—yet

Posted on July 12, 2017 by Amber Dance

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: In a first, deep sea robots get a close look at giant larvaceans, a key player in the biological carbon pump

Posted on May 3, 2017 by Gayathri Vaidyanathan

Closer inspection of the giant larvacean, seen here in an undersea video taken by a remotely operated vehicle, could reveal clues about how the deep sea sequesters carbon. Image Credit: © 2017 MBARI In the deeps off Monteray Bay, Calif., … Continue reading →

Journal Club: Geometry of Greenland’s glaciers helps predict future ice melt

Posted on April 28, 2017 by Amber Dance

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

Posted on March 24, 2017 by Danielle Venton

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: Landscape connectivity key to future animal migration needs in the United States

Posted on June 13, 2016 by Charles Choi

As the climate changes, plants and animals worldwide are migrating to follow their preferred conditions. Human activity, however, can impede these movements. Now researchers are mapping out ways to help species escape to more suitable climes. The scientists detailed their … Continue reading →

Journal Club: Maya altered their environment significantly, for better or worse

Posted on October 5, 2015 by Charles Choi

The ancient Maya once had a civilization in the Americas that stretched over an area the size of Texas. Now scientists detail a number of key ways the Maya left behind a lasting impact on the environment during the so-called … Continue reading →

New forests change land temperatures

Posted on April 1, 2014 by pnas

Thirty years ago China began launching ambitious reforestation projects, aiming to undo some of the massive environmental damage caused by years of clear cutting. Each year the country adds around 2 million hectares of new trees, with no sign of … Continue reading →
