A group of BYU engineering students wants to start a solar-cell revolution.

Led by mechanical engineering professor John Salmon, the students hope to trigger energy change by installing solar cells in public locations you wouldn’t think of, such as:

• Bus stops
• Park picnic tables and benches
• Cafeterias and restaurants
• Car window shades
• Stadium Seats
• Blinds

Particularly under threat are honey bees, which are as vital to our food systems as the crops they pollinate, and which are prone to a range of emergent diseases including Moku and Deformed wing virus (DWV).

The Moku virus was identified through a collaboration of institutes with complementary expertise.

Purnima Pachori of the Platforms & Pipelines Group at the Earlham Institute (EI) carried out the bioinformatics work of separating out host and viral genetic material, which allowed for the analysis and identification of the novel Moku virus led by Gideon Mordecai (based at the time at the Marine Biological Association (MBA), Plymouth).

The ability to self-repair damaged tissue is one of the key features that define living organisms. Plants in particular are regeneration champions, a quality that has been used for centuries in horticultural techniques such as grafting. Belgian scientists from VIB and Ghent University have now discovered a key protein complex that controls plant tissue repair. Understanding this mechanism is of great agricultural importance: crops and edible plants might be cultivated more efficiently and made more resistant to parasitic plants. The results are published in the leading journal Nature Plants. 

 

On a recent afternoon, University of Florida watershed ecologist David Kaplan and Ph.D. candidate Katie Glodzik hiked through the Withlacoochee Gulf Preserve, on the Big Bend coast of northwestern Florida. Not long ago, red cedar, live oaks, and cabbage palms grew in profusion on the raised “hammock island” forests set amid the preserve’s wetlands. But as the researchers walked through thigh-high marsh grass, the barren trunks of dead cedars were silhouetted against passing clouds. Dead snag cabbage palms stood like toothpicks snapped at the top. Other trees and shrubs, such as wax myrtle, had long been replaced by more salt-tolerant black needlerush marsh grass. 

The western-most region of the continental United States set records for low snowpack levels in 2015 and scientists, through a new study, point the finger at high temperatures, not the low precipitation characteristic of past “snow drought” years.

The study suggests greenhouse gases were a major contributor to the high temperatures, which doesn’t bode well for the future, according to authors of a new study published today in the journal Geophysical Research Letters. 

Such changes mean species threatened by climate change may find ways to adapt far quicker than through changes in DNA, which come with evolution.

Researchers studied the Winter Skate (Leucoraja ocellata), in waters that are around 7000 years old and significantly warmer than those where the rest of the species range is found. They observed many physical and functional adaptations which allow the species to cope with the significantly different set of environmental conditions observed in this shallow, warm habitat.

New Cornell University research suggests an economically viable model to scrub carbon dioxide from the atmosphere to thwart global warming.

The researchers propose using a “bioenergy-biochar system” that removes carbon dioxide from the atmosphere in an environmental pinch, until other removal methods become economically feasible and in regions where other methods are impractical. Their work appeared in the Oct. 21 edition of Nature Communications.

U.S. colleges and universities are increasingly deploying solar arrays and other forms of renewable energy. Yet most institutions have a long way to go if they are to meet their goal of being carbon neutral in the coming decades.

The soul of Arizona State University is Memorial Union, a hulking brick-and-glass community center that opens onto a sprawling pedestrian mall. Although the building sits at the heart of campus, its outdoor plaza was once virtually uninhabitable for four months each year, when summer temperatures in scorching Tempe often hover over 100 degrees. So in 2014, the university – Arizona’s leading energy consumer – completed construction on a PowerParasol, a 25-foot-tall shade canopy composed of 1,380 photovoltaic solar panels capable of producing 397 kilowatts of electricity.

The idea of eating bugs has created a buzz lately in both foodie and international development circles as a more sustainable alternative to consuming meat and fish. Now a report appearing in ACS’ Journal of Agricultural and Food Chemistry examines how the nutrients — particularly iron — provided by grasshoppers, crickets and other insects really measures up to beef. It finds that insects could indeed fill that dietary need.

Plants are adapting to increasing atmospheric carbon dioxide according to a new study from the University of Southampton

The research, published in the journal Global Change Biology, provides insight into the long-term impacts of rising CO2 and the implications for global food security and nature conservation.

Lead author Professor Gail Taylor, from Biological Sciences at the University of Southampton, said: “Atmospheric CO2 is rising – emissions grew faster in the 2000s than the 1990s and the concentration of CO2 reached 400 ppm for the first time in recorded history in 2013.
