The National Center for Atmospheric Research will fly a C-130 research aircraft over Colorado’s Front Range this May and July to measure how much carbon dioxide mountain forests remove from the air as spring turns into summer. NCAR scientists and their university colleagues are developing new methods for assessing carbon uptake over complex terrain on regional scales. Accurate assessments could help show to what extent carbon dioxide storage in Western mountain forests-- a potentially important "sink" for the greenhouse gas--may be slowing down as the ongoing drought affects tree growth.
International pressure is mounting to limit carbon emissions because of their role in global climate change. Better understanding of natural processes involved in forest-air carbon exchange may lead to more accurate monitoring methods and new ways to enhance carbon uptake. High carbon-emitting nations and industries are interested in devising strategies for meeting quotas and trading carbon credits.
ACME (short for the Airborne Carbon in the Mountains Experiment) gives scientists an opportunity to combine airborne data with ground-based measurements for the first time to paint a more accurate picture of carbon exchanges in rolling hills and mountain ranges. Results from the field program will also be used in testing computer models of forest ecosystem function. The models will help scientists understand the response of forests to drought, fire, insects, and climate change.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
