Tuberculosis (TB) is a prevalent infectious disease that affects millions of people each year. It was previously the leading cause of death from a single pathogen before the COVID-19 pandemic. Detecting TB early is challenging because the bacterium Mycobacterium tuberculosis (Mtb) can hide in human macrophages, which are part of the immune system
Some Covid-19 vaccines safely and effectively used lipid nanoparticles (LNPs) to deliver messenger RNA to cells. A new MIT study shows that different nanoparticles could be used for a potential Alzheimer’s disease (AD) therapy.
Researchers at the Francis Crick Institute, UCL and MSD have identified a potential treatment target for a genetic type of epilepsy. Developmental and epileptic encephalopathies are rare types of epilepsy which start in early childhood. One of the most common types of genetic epilepsy, CDKL5 deficiency disorder (CDD), causes seizures and impaired development.
Researchers at Linköping University, Sweden, have examined the brains of 16 patients previously hospitalised for COVID-19 with persisting symptoms. They have found differences in brain tissue structure between patients with persisting symptoms after COVID-19 and healthy people. Their findings, published in the journal Brain Communications, can bring insights into the underlying mechanisms of persisting neurological problems after COVID-19.
A woman who never developed Alzheimer's despite a strong genetic predisposition may hold the key to stopping the disease in its tracks.

James Boland, an acoustician for SLR Consulting, employed insights from the field of sensory criminology to better understand the unique acoustic needs inside prison environments. By focusing on speech intelligibility, strategic reduction of noise levels, and the incorporation of privacy considerations, acoustic design can significantly improve the overall prison environment. Creating distinct zones within the prison and balancing moments of quiet with activity are essential to fostering a more comfortable and secure space.
Aggression is often associated as a negative emotion. Uncontrolled aggression can lead to conflict, violence and negative consequences for individuals and society. Yet that does not that mean that aggression serves no purpose. It is an instinctive behavior found in many species that may be necessary for survival. The key is managing and channeling aggression.
Mice typically live two years and monkeys live 25 years, but the brains of both appear to develop their synapses at the same time. This finding, published in a recent study led by neuroscientist Bobby Kasthuri of the U.S. Department of Energy’s (DOE) Argonne National Laboratory and his colleagues at the University of Chicago, is a shock for neuroscientists.
In some diseases, the underlying processes can start years before a diagnosis is made. A new study finds that people who later develop multiple sclerosis (MS) are more likely to have conditions like depression, constipation and urinary tract infections five years before their MS diagnosis than people who do not develop MS.
What happens in the brain to cause many neurodevelopmental disorders, including autism spectrum disorder (ASD), remains a mystery. A major limitation for researchers is the lack of biomarkers, or objective biological outputs, for these disorders, and in the case of ASD, for specific subtypes of disease.
In this study of 2,574 participants with obstructive sleep apnea, compared with participants with objective sleep duration of at least seven hours, those sleeping less than seven hours had higher risks of all-cause mortality independent of apnea-hypopnea index.
