Journal Club: How to measure the global potential for biomass vegetation

Posted on January 12, 2018 by Carolyn Beans

Plants play a big role in removing carbon from the atmosphere. Almost a quarter of carbon from car exhaust and industry gets absorbed by vegetation. That’s a significant amount. But a recent study suggests that amount has the potential to … Continue reading →

Journal Club: Wheat’s molecular response to full sun exposure could suggest ways to increase yield

Posted on August 25, 2017 by Carrie Arnold

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: 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 →

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 →

Journal Club: Cultivated sweet potatoes were genetically modified — naturally

Posted on April 23, 2015 by Charles Choi

The first genetically modified foods were not human creations. Scientists have now found that sweet potatoes all over the world naturally contain bacterial genes that the microbes introduced. Such transgenes may have provided attractive traits for domestication, researchers added. The … Continue reading →

Journal Club: Genetic detective work suggests a crucial role for Maya in papaya domestication

Posted on March 25, 2015 by Charles Choi

Papaya is a multimillion-dollar crop with a complicated sex life. Now plant geneticist Ray Ming at the University of Illinois at Urbana-Champaign and his colleagues find that hermaphrodite papayas, the version most useful to farmers, most likely arose due to … Continue reading →
