“We’ve been working to create trees that grow faster and produce more wood, and what this research shows is that at the same time we’re enhancing environmental quality by scrubbing as much carbon out of the atmosphere as we possibly can,” says Dr. John King, an NC State forest ecologist and co-author of a paper published this month in the journal Forest Science.
The study estimated a 17 percent increase in stem-wood production and a 13 percent increase in carbon uptake in improved loblolly pines planted throughout the Southeast between 1968 and 2007. Three generations of enhanced seedlings were released over that 40-year period.
Pine plantations cover about 15 percent of forested land in the South. Each year, almost a billion loblolly pine seedlings are planted, typically taking 25 years to reach maturity.
“We’re reaping the benefits today of work our predecessors did, and our work will affect our children and grandchildren,” says co-author Dr. Steve McKeand, NC State forestry professor and director of the Cooperative Tree Improvement Program, a public/private partnership founded in 1956.
The study marks one of the first attempts to quantify the effects of improved tree genetics on carbon sequestration across a large landscape, McKeand and King say.
The lead author of the study, Dr. Mike Aspinwall of the University of Texas at Austin, worked with McKeand and King while completing his doctorate at NC State.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
