Scientists create composite maps of the world's 'net primary production' every 8 days, revealing how much carbon dioxide is taken in by vegetation during photosynthesis. The new measurement provides a global perspective on the Earth's carbon cycle and has implications for climate change, agriculture, and ocean productivity.
Jacek Sekutowicz, a visiting senior scientist at Jefferson Lab, is leading the way in cavity redesign as part of a proposed 12 GeV upgrade. He and his colleagues aim to reduce or eliminate parasitic modes using high order mode couplers, resulting in highly efficient beam passage through the cavities.
The National Institute of Environmental Health Sciences is conducting a study to investigate the causes of rheumatic diseases, including lupus and scleroderma. The research focuses on identical twins and close siblings, collecting blood and urine samples to examine environmental exposures and genetic variations.
Research Points highlights four key actions for policymakers: think about alignment from the start, conduct analysis using multiple criteria, consider standard revisions, and update alignment studies. The series also provides examples of common challenges in test alignment and how to determine sufficient alignment.
Researchers have developed a system that can alter pitch, duration, and vibrato in singing voices, producing more professional-sounding renditions. The technology uses a sinusoidal model to break down the original voice into components that can be modified to produce a great singing voice.
AERA honors James B. Hunt Jr. for his commitment to using education research in policy-making, resulting in improved student performance in North Carolina. The former governor received the Public Service Award at AERA's Annual Meeting in Chicago.
Professor Phil Gans predicts that volcanic eruptions in Costa Rica are 'inevitable' and could lead to devastating pyroclastic flows. He studied volcanic rocks and found evidence of subduction-related volcanism dating back 24 million years, with major eruptions occurring every few thousand years.
Researchers at Jefferson Lab are conducting an experiment to demonstrate energy recovery, which could lead to more efficient and powerful accelerators. By recirculating high-energy electrons, they aim to reduce RF energy usage while maintaining beam quality.
The quality of care in nursing homes remains a significant challenge, with many experts arguing that public reporting may hasten the demise of low-performing facilities and create a void without clear solutions. A balanced long-term care system is needed to address issues such as staffing, financing, and care delivery.
Rocco Schiavilla, Interim Theory Group Leader at Jefferson Lab, was elected APS Fellow in 2002 for his work on nuclei as systems of protons and neutrons interacting via many-body potentials. His research focuses on the development and application of this picture to explain nuclear properties over a wide range of energies.
A study of US women's suicides found that white women are three times more likely to die by suicide than black women. The key findings suggest the need for targeted prevention programs and better data collection on suicidal behaviors.
