A study in a mouse model found that viral infections during pregnancy can affect the mother's brain and disrupt maternal care behavior after birth. The research team identified structural, molecular, and functional changes in the brains of mothers with viral-like immune activation.
Researchers found that repetitive exposure to environmental hypoxia prevented memory loss and reversed impairments in nerve-to-nerve communication. Adult offspring also inherited this protection against dementia.
The University of South Florida has received a five-year, $1.35 million NIH institutional grant to train scientists in vascular inflammation and injury research. The grant will support the comprehensive training of pre- and postdoctoral scientists focused on this emerging area of research.
Complimentary press passes are available for the EB 2022 meeting, featuring cutting-edge research and live scientific sessions. The event will also offer virtual access to press materials.
A Tel Aviv University study found a significant link between changes in G-protein-coupled receptors and brain adaptability. Disabling the voltage sensor of these proteins caused uncontrolled brain flexibility, leading to excessive habituation to odors.
Researchers discovered that living cell interiors become softer and more fluid during mitosis, a process crucial for life. The findings could help ensure precise separation of cellular structures into daughter cells.
Jochen Zimmer, a UVA professor, has been awarded $9 million by the HHMI to pursue his research on biopolymer transport across biological membranes. His work aims to develop new biomaterials for medicines, food, and energy, potentially combating diseases, hunger, and climate change.
Research by University of Arizona Health Sciences identifies chronic arsenic exposure as a risk factor for developing insulin resistance and glucose intolerance. The study found that prolonged activation of NRF2 protein leads to shifts in metabolic pathways, increasing glucose production in the liver.
A new preclinical study validates the spleen's role in cardiac healing and suggests targeting S1P as a potential treatment for heart failure. The study discovered interactions between S1P and the heart during transition from acute to chronic heart failure.
Scientists at Weill Cornell Medicine developed a computational technique that greatly increases the resolution of atomic force microscopy, revealing atomic-level details on proteins and biological structures. The new method allows researchers to study biological molecules under physiologically relevant conditions, providing high-resolu...
Researchers at HKUST create a novel optical tweezers-coupled Raman spectroscopy platform to analyze proteins in low concentrations, particularly IDPs. The study successfully characterizes the structural features of alpha-synuclein, an IDP linked to Parkinson's disease, at physiological concentration.
A clinical trial of alternate-day fasting found health benefits, including reduced inflammation and improved cholesterol levels. Participants experienced a mean calorie restriction of about 35% and lost an average of 3.5 kg during four weeks.
Researchers found that even low levels of traffic-related air pollution can cause inflammation and mitochondrial damage in the lungs of mice. The study's results suggest that people living alongside major traffic corridors should be aware of potential respiratory health risks.
Researchers at the University of Vermont have discovered that myosin-binding protein C (cMyBP-C) is essential for maintaining precise tuning in the heart's muscle cells. The protein plays a crucial role in controlling the interaction between myosin and actin, allowing for synchronized contraction and efficient pumping of blood.
The Scandinavian Plant Physiology Society (SPPS) has renewed its partnership with Wiley over sixty years ago. The journal Physiologia Plantarum, an international thought leader in plant physiology, benefits from the collaboration.
