Dr. Zhaocai Zhou, head of a GC laboratory from Fudan University, stated.
Rural Americans are less likely to initiate care for substance use disorders and to receive ongoing care compared with those who live in urban areas. When they do access care, people who live in less populated areas are more likely to have to go outside their provider network to receive treatment, which comes with higher out-of-pocket costs.

To this day, no one knows for certain what caused the liver and kidney disease that led to Ludwig van Beethoven’s untimely death. However, a new letter to the editor in the Association for Diagnostics & Laboratory Medicine’s (ADLM’s, formerly AACC’s) journal Clinical Chemistry rules out one popular theory, showing that the composer was exposed to lead levels that were high — but not high enough to kill him.

How well a newly minted doctor scores on their medical board exam appears linked to patients’ odds of dying or being readmitted to the hospital. Findings offer reassurance that certification exams, which aim to demonstrate the competence of physicians, capture critical knowledge and clinical judgment skills for physicians.
In research that may be a step forward toward finding personalized treatments for Tourette disorder, scientists at Rutgers University–New Brunswick have bred mice that exhibit some of the same behaviors and brain abnormalities seen in humans with the disorder. As reported in the Proceedings of the National Academy of Sciences, the researchers, using a technique known as CRISPR/Cas9 DNA editing, inserted the same genetic mutations found in humans with Tourette disorder into the corresponding genes in mouse embryos.

A study led by Yale scientists, published April 25 in the journal Science Immunology, investigated the potential causes associated with T cell exclusion using a genome-wide screen of more than 1,000 human proteins.
Study reveals VR's potential in revolutionizing depression treatment, offering hope to millions worldwide.
Berkeley Lab scientists have achieved record-high energy and power densities in microcapacitors made with engineered thin films, using materials and fabrication techniques already widespread in chip manufacturing.
New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies.
Researchers from University of California San Diego have developed a new AI tool to that generate new drug candidates for cancer, which could help streamline the typically laborious drug discovery process.

Wellesley, Mass. – New research by Wellesley College professor Jeremy Wilmer and colleagues has produced an accurate and inclusive test of mindreading, or theory of mind.
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.
Conventional metals cannot conduct light in their interiors, but scientists have discovered that in the quantum metal ZrSiSe, electrons can give rise to plasmons.
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.
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.
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.
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.

• Two complementary research articles, published simultaneously in the journals Science and Cell Stem Cell by a team of scientists from the UPF and IRB Barcelona, reveal that central and peripheral circadian clocks coordinate to regulate the daily activity of skin and muscles. • The coordination between the two clocks (central and peripheral) guarantees 50% of the circadian functions of tissues, including vital processes such as the cell cycle, DNA repair, mitochondrial activity, and metabolism. • Synchronisation between the central brain clock and peripheral ones prevents premature muscle ageing and improves muscle function, suggesting new strategies to tackle age-related decline through circadian rhythm modulation.
Most analyses point to agriculture as the major source of nitrous oxide (N2O) globally. But there are a lot of variables within agriculture that can affect emissions. A recent University of Illinois Urbana-Champaign study provides a comprehensive accounting for these factors, finding, among other things, that long-term no-till management can effectively cut N2O emissions.
