AI can improve Alzheimer's treatment through the 'gut-brain axis'      (via sciencedaily.com)     Original source 

Researchers are using artificial intelligence to uncover the link between the gut microbiome and Alzheimer's disease. Previous studies showed that Alzheimer's disease patients have changes in their gut bacteria as the disease develops. The study outlines a computational method to determine how bacterial byproducts called metabolites interact with receptors on cells and contribute to Alzheimer's disease.

Switching off the light to see better      (via sciencedaily.com)     Original source 

Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of images that surpassed the conventional resolution limit, and it may be useful for further study of cell clusters and other biological systems.

Protein network dynamics during cell division      (via sciencedaily.com)     Original source 

An international team has mapped the movement of proteins encoded by the yeast genome throughout its cell cycle. This is the first time that all the proteins of an organism have been tracked across the cell cycle, which required a combination of deep learning and high-throughput microscopy.

The enemy within: How pathogens spread unrecognized in the body      (via sciencedaily.com)     Original source 

Some pathogens hide inside human cells to enhance their survival. Researchers have uncovered a unique tactic certain bacteria use to spread in the body without being detected by the immune system. In their study, they reveal the crucial role of a bacterial nanomachine in this infection process.

Surf clams off the coast of Virginia reappear -- and rebound      (via sciencedaily.com)     Original source 

The Atlantic surfclam, an economically valuable species that is the main ingredient in clam chowder and fried clam strips, has returned to Virginia waters in a big way, reversing a die-off that started more than two decades ago. In a comprehensive study of surfclams collected from an area about 45 miles due east from the mouth of the Chesapeake Bay, scientists found the population to be thriving and growing.

Key protein regulates immune response to viruses in mammal cells      (via sciencedaily.com)     Original source 

Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.

Light show in living cells      (via sciencedaily.com)     Original source 

Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.

Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?      (via sciencedaily.com)     Original source 

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.

Potential new treatment path for lasting Lyme disease symptoms      (via sciencedaily.com)     Original source 

Researchers have identified a potential new treatment for persistent neurological symptoms of Lyme disease, commonly seen even after antibiotic use. The study found that fibroblast growth factor receptor inhibitors, previously studied in cancer, significantly reduced inflammation and cell death in infected brain and nerve tissues.

Metabolic health before vaccination determines effectiveness of anti-flu response      (via sciencedaily.com)     Original source 

The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings showed switching mice to a healthy diet four weeks before influenza vaccination protected 100% from a later flu exposure, despite still having a high BMI.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future      (via sciencedaily.com)     Original source 

The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.
