CDC Issues Health Advisory Following the Republic of Rwanda’s First Outbreak of Marburg Virus Disease
On October 2, 2024, the Republic of Rwanda confirmed its first outbreak of Marburg virus disease (MVD) with 36 laboratory-confirmed cases and 11 deaths (31 percent case fatality rate), including 19 cases in healthcare workers largely working in intensive care units or ICUs.
New X-ray technique reveals metal ion role in antibiotic efficacy
Researchers from City St George's, University of London have used a new ultra-high precision x-ray scattering technique to unveil the location and identity of metal ions in bacteria that are crucial for antibiotics to work optimally.
Understanding the Mechanical Forces in Gene Expression
New research sheds light into how tension and torsion affect gene transcription
AI ‘Liquid Biopsies’ Using Cell-Free DNA, Protein Biomarkers, Could Aid Early Detection of Ovarian Cancer
The blood test that uses artificial intelligence (AI) to detect cancer-related genetic changes and protein biomarkers could help screen women for early signs of ovarian cancer
Unlocking the mystery of the fruit fly's internal compass
For decades, researchers theorized about how an animal's brain keeps track of where it is relative to its surroundings without outside cues – like how we know where we are, even with our eyes closed.
A new theory shows how it is possible to create a perfectly accurate internal compass with a very small network.
Researchers fully map neural connections of the fruit fly brain
A scientific team supported by the National Institutes of Health (NIH) unveiled the first complete map of the neural connections of the common fruit fly brain. The map provides a wiring diagram, known as a connectome, and is the largest and most complete connectome of an adult animal ever created.
Understanding the brain’s process of dividing experiences into events
The moment a person steps off the street and into a restaurant-;to take just one example-;the brain mentally starts a new "chapter" of the day, a change that causes a big shift in brain activity. Shifts like this happen all day long, as people encounter new environments, like going out for lunch, attending their kid's soccer game, or settling in for a night of watching TV.
But what determines how the brain divides the day into individual events that we can understand and remember separately?
ECRI Study Finds Errors During Testing Processes Are Responsible for Most Diagnostic Errors
Researchers note that many sources of errors associated with diagnostic testing involve how providers order tests and how specimens are handled.
LXRβ emerges as a promising target for depression and anxiety treatments
LXRβ, a nuclear receptor initially known for its role in cholesterol metabolism and inflammation, is now emerging as a crucial player in neuroscience and psychiatry. The review synthesizes recent breakthroughs in understanding LXRβ's regulation and function in behaviors relevant to depression and anxiety, derived from studies using animal models that capture specific features of these disorders
