Sneaky salmonella finds a backdoor into plants
Researchers have discovered that bacteria such as salmonella, E. coli and listeria have a backdoor to take advantage of humans’ reliance on leafy greens for a healthy diet. They found that wild strains of salmonella are delivering foodborne illnesses by circumventing a plant’s immune defense system, getting into the leaves of lettuce by opening up the plant’s tiny breathing pores.
A carbon sink shrinks in the Arctic
Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean’s ability to absorb carbon dioxide from the atmosphere into the deep ocean and store it there.
Protecting bays from ocean acidification
(University of Delaware) As oceans absorb more man-made carbon dioxide from the air, a process of ocean acidification occurs that can have a negative impact on marine life. But coastal waterways, such as Chesapeake Bay, can also suffer from low oxygen and acidification. New research from the University of Delaware identifies one way to protect these waterways — the presence of submerged aquatic vegetation (SAV).
Measuring climate change
(University of Delaware) University of Delaware professor Wei-Jun Cai teamed with the National Oceanic and Atmospheric Administration (NOAA) scientists, as well as professors and professionals from numerous research institutes, to conduct an in-depth study that looks at carbon dioxide uptake and ocean acidification in the coastal oceans of North America.
Managed Retreat in the Face of Climate Change, Part 2
In the second episode of a two-part podcast interview for CleanTech Talk, Michael Barnard, Chief Strategist of TFIE Strategy Inc. and CleanTechnica contributor, and A.R. Siders, core faculty at the University of Delaware’s Disaster Research Center, continue their talk about A.R.’s work as a preeminent U.S. researcher in managing retreat in the face of climate change
