The research team proposes a deep learning-based framework that can generate ultrasound holograms in real time, enabling precise and quick beam focusing. This technology has the potential to be used in patient-specific precision brain stimulation and general ultrasound fields.
A US study of 15,000 nursing homes found that pre-Omicron vaccination boosts reduced COVID-19 cases and deaths among residents and staff. Newer variants rendered original vaccine less effective.
Researchers developed an eco-friendly porous polymer material that removes phenolic organic contaminants and microplastics from water at ultra-high speeds. The material can be reused multiple times without losing performance, making it a promising solution for efficient water purification.
Researchers developed predictive models using serum microRNAs to identify patients at risk of requiring early palliative care. The study used serum samples from 178 patients with various types of cancer and found that miRNA-based models had higher accuracy than clinical models in predicting referral to a palliative care unit.
Researchers at WashU Medicine identified a key transition point in the shift from chronic to aggressive leukemia, where blocking a molecule called DUSP6 prevents disease progression. Inhibiting this molecule also reduces inflammation in models of the disease.
A new microresonator technology is being developed to analyze chemicals using light, enabling faster diagnosis of diseases like COVID and diabetes. The device can retain light waves for longer periods, amplifying optical fields and making nonlinear processes easier.
Researchers at MIT's Picower Institute found that the brain stores information in working memory by making short-lived changes in neural connections, contradicting the traditional idea of sustained neuronal activity. This new insight sheds light on the sophisticated flexibility of thought and its dynamic nature.
Research team led by Prof. Lin Zhuang found that guanine modification boosts CH4 production and suppresses C2 product formation in electrochemical CO2 reduction. The results suggest a direct correlation between surface proton transfer capability and CO2 reduction selectivity.
The study found that ransomware attacks on healthcare organizations have more than doubled, exposing personal health information of nearly 42 million patients. The attacks grew larger in quantity and likelihood to affect large organizations with multiple facilities.
Researchers discovered a point mutation in the fruit fly Drosophila melanogaster that leads to a temperature-dependent lengthening of circadian clock periods. The mutation affects the nuclear export signal of the PERIOD protein, resulting in its retention in the cell nucleus at higher temperatures.
A study of 187 cancer patients found that delaying antibiotic treatment past 60 minutes didn't affect their 6-month survival rate. However, factors such as symptom severity and time to hospital admission were associated with increased risk of death.
Patients with cancer are at a higher risk of SARS-CoV-2 infection and worse outcomes than those without cancer. Triple vaccination is associated with a lower risk of poor outcomes in these patients.
Researchers at SUNY Optometry aim to provide a deeper understanding of the biology of myopia, a leading cause of vision impairment worldwide. The study will investigate cellular and molecular mechanisms controlling eye growth and develop new treatments for refractive errors.
A 16-year longitudinal study found associations between DNA methylation-based measures and neuropsychologically-validated cognitive decline in midlife. The results suggest that these measures may serve as biomarkers for a molecular aging mechanism, potentially identifying individuals at risk of cognitive impairment and dementia.
Researchers at CELIA have developed a laser drilling method that creates elongated, crack-free micro-holes in glass. This breakthrough allows for high-aspect ratio holes with smooth inner walls, enabling new applications in microelectronics.
Researchers demonstrate that a dual-site cooperative catalytic mechanism on Ru-S-C single-atom catalyst significantly enhances electrochemical nitrogen reduction. The Ru/S dual site facilitates the activation and first protonation of N2 in the rate-determining step, leading to improved activity and selectivity.
Macrophage PPARγ acetylation decreases energy expenditure and worsens insulin sensitivity, glucose tolerance, and lipid metabolism in mice fed a high-fat diet. This impairment promotes macrophage infiltration, adipose fibrosis, and hepatic steatosis.
Researchers developed solid electrolytes with enhanced atmospheric stability, addressing lithium-ion battery safety concerns. The LLZO electrolyte was improved through gallium and tantalum doping, maintaining high conductivity even in air.
A new paper highlights the need for globally harmonized probiotic regulatory approaches, emphasizing the importance of comprehensive genomic characterization. It proposes a risk-tier system based on strain history and genome analysis, recommending more extensive testing for innovative strains before marketing.
Researchers found no evidence of a critical mass needed to start and maintain new research fields. Instead, pioneering regions with early investment can establish dominance. However, late-comers face significant costs to catch up, as seen in China's semiconductor science, where strategic interventions over decades led to a dominant role.
