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.

Adapting to climate change – a major challenge for forests
Climate change means that trees germinating today will be living in a much-altered climate by the time they reach middle age. The expected changes are likely to hit them hard and threaten key forest functions in the decades ahead. However, appropriate management shall enable to increase the forest habitat's adaptability. This is shown by the results of the Forests and Climate Change research programme conducted by the Swiss Federal Office for the Environment FOEN and the Swiss Federal Institute for Forest, Snow and Landscape Research WSL since 2009.
Cloudy feedback on global warming
Lawrence Livermore National Laboratory researchers have identified a mechanism that causes low clouds -- and their influence on Earth's energy balance -- to respond differently to global warming, depending on their spatial pattern and location.
The results imply that studies relying solely on recent observed trends underestimated how much Earth will warm due to increased carbon dioxide. The research appears in the Oct. 31 edition of the journal, Nature Geosciences
Ghost Forests: How Rising Seas Are Killing Southern U.S. Woodlands
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 Other trees and shrubs, such as wax myrtle, had long been replaced by more salt-tolerant black needlerush marsh grass.
West Coast record low snowpack in 2015 influenced by high temperatures
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.
In the right place at the right time
Based on a unique dataset collected during a research cruise to the Irminger Sea in April 2015, a new paper reveals a strong link between atmospheric forcing, deep convection, ocean ventilation and anthropogenic carbon sequestration.
The Irminger Sea, a small ocean basin between Greenland and Iceland, is known for its harsh and extreme weather conditions during winter. Research cruises that take measurements in the subpolar North Atlantic almost exclusively do so in summer, although the area is particularly interesting in the convectively active winter season.
