reforestation models have been over exaggerated — and not by a small factor — but by as many as three times of a factor. The goal set by the Paris Agreement in 2015 for countries to limit their global warming to 1.5 degrees is now close to being surpassed.
Conventional metals cannot conduct light in their interiors, but scientists have discovered that in the quantum metal ZrSiSe, electrons can give rise to plasmons. These are collective oscillations in a material that are strong and long lived, and they can combine with photons to form new modes called polaritons that can carry photons along zig-zag paths in the material.
Potassium-40 usually decays to calcium-40, but about 10 percent of the time it decays to argon-40 through electron capture. One variant of this decay path ends in argon-40 in its ground state. The rate of this decay is important for using argon-40 to determine the age of geologic features and studying neutrinoless double beta decay. Researchers recently made the first direct observations of this very rare but critical decay path.
The quark Sivers function describes much of the physics of how quarks are distributed in a proton whose rotation is perpendicular to its direction of motion. This function shows whether more quarks in the proton move to the right than to the left of the plane created by the proton’s velocity and the direction of the proton’s rotation (spin) axis. Scientists have found a new theoretical contribution to the Sivers function of the quarks carrying a small fraction of the proton’s momentum.
Research led by scientists at the Department of Energy’s Oak Ridge National Laboratory has demonstrated that small changes in the isotopic content of thin semiconductor materials can influence their optical and electronic properties, possibly opening the way to new and advanced designs with the semiconductors.
The Virginia Tech media relations office has the following experts available for interviews surrounding a variety of topics and research ahead of this summer’s Olympic Games in Paris. To schedule an interview, please contact [email protected]. Can Paris be the model for a more viable, sustainable Olympic host city? The 2024 Paris Summer Games are the first real test for the International Olympic Committee’s Olympic Agenda 2020, a set of 40 recommendations intended to restore the Olympic values.
Rutgers Health researchers examine connections between mental health wellness education among correctional officers and support for at-risk incarcerated individuals
Follow-on analysis of results from the phase 3 PSMAfore study, along with the overall study results, support the consideration of 177Lu-PSMA-617 as a new standard treatment approach for this prevalent population of patients with mCRPC. Research led by Dana-Farber Cancer Institute and others.
A team of University of Miami scientists and others recently spent weeks in the Arctic region studying marine cold-air outbreaks and how the clouds they produce can lead to extreme weather events and may be interacting with the rapidly warming Arctic.
Tantalum superconducting material shows great promise for making qubits. When an oxide layer forms on the surface of tantalum, it can lead to quantum decoherence. In this study, researchers used scanning transmission electron microscopy (STEM) and computer modeling to investigate the structure of superconducting tantalum film. This helped them build an atomic-level understanding of the crystalline lattice of tantalum metal and the oxide that forms on its surface.
X-ray bursts occur on the surface of a neutron star as it absorbs material from a companion star. This absorption initiates a cascade of thermonuclear reactions that create atoms of heavy chemical elements on the surface of a neutron star. Researchers have directly measured one of these reactions, finding it to be four times higher than the previous direct measurement.
The Wistar Institute assistant professor Dr. Filippo Veglia has discovered a key mechanism of how glioblastoma — a serious and often fatal brain cancer — suppresses the immune system so that the tumor can grow unimpeded by the body’s defenses.
Pitch of experts and patients regarding mental health awareness month
The artificial intelligence (AI) chatbot called ChatGPT is a powerful way for Black women to educate themselves about HIV prevention, as it provides reliable and culturally sensitive information, according to a study in The Journal of the Association of Nurses in AIDS Care (JANAC), the official journal of the Association of Nurses in AIDS Care.
Below are summaries of recent Fred Hutch Cancer Center research findings, patient stories and other news.
A new approach to gene therapy resets cell homeostasis. Clinical trials to treat the retinal disorders Retinitis Pigmentosa, Stargardt's, and Geographic Atrophy (late dry macular degeneration) are underway and showing promise.
Researchers from the National Autonomous University of Mexico, together with physicians of the Fray Bernardino Álvarez Psychiatric Hospital in Mexico city, have conducted a study, which demonstrated that male subjects with suicidal behavior who had not sought psychological or psychiatric assistance were likely to select more violent suicide methods compared to female subjects.
The world’s largest study of cerebral palsy (CP) genetics has discovered genetic defects are most likely responsible for more than a quarter of cases in Chinese children, rather than a lack of oxygen at birth as previously thought.
