The current system has led to a significant drop in spending on such campaigns, while providing £473 million in tax breaks to top-grossing films featuring tobacco imagery.
Dr. Diane Mathis has been awarded the FASEB Excellence in Science Award for her groundbreaking research on immunological tolerance, autoimmune diseases, and immune regulation. Her numerous publications and teaching achievements have also made a significant impact on the field of immunology.
New research found that CD4 T-cells in young mice secrete lower levels of interferon gamma, a key antiviral cytokine, leading to higher rates of immune cell death and delayed virus clearance. This may explain children's increased susceptibility to illnesses.
A new E. coli-based transport capsule has been developed to improve the efficiency of next-generation vaccines, with promising results in fighting pneumococcal disease. The capsule uses a harmless strain of E. coli wrapped in a synthetic polymer to deliver antigens and trigger an immune response.
Researchers from Rush University Medical Center found that diseased blood vessels in the brain may contribute more significantly to Alzheimer's disease dementia than previously believed. The study analyzed medical and pathologic data on 1,143 older individuals and found an association between worsening brain vessel diseases and higher ...
Researchers at Osaka University have identified H4K20ac, a novel histone modification associated with gene repression. This finding has significant implications for understanding the development of metabolic disorders, cardiovascular diseases, and cancer.
A new study finds that prenatal exposure to paracetamol may increase attention-related symptoms, hyperactivity, and autism spectrum symptoms in children. Researchers found a 30% higher risk of attention function detriment and two clinical autism symptoms in boys exposed to paracetamol during pregnancy.
The UTA Institute of Urban Studies is analyzing pedestrian traffic along 184 street segments and 66 intersections in downtown Dallas to understand the street-level experience. The study will capture characteristics like density, block size, and building uses to identify elements that impact walkability.
A new study found that individual mycobacteria respond differently to antibiotics based on growth and timing, shedding light on the complexity of antibiotic tolerance. Bacteria in different stages of their cell cycle and size are susceptible to varying degrees.
Researchers at the University of Wisconsin-Madison have confirmed that a benign bacterium called Wolbachia pipientis can completely block transmission of Zika virus in Aedes aegypti mosquitoes. The bacteria, which are self-sustainable and low-cost, can also reduce vector competence in mosquitoes and impact their infection status.
A University of Houston researcher is exploring electron oscillation in porous gold nanoparticles to harness their energy. The goal is to enhance catalytic reactions and boost biosensing, potentially leading to ultrasensitive detection of disease biomarkers.
