Magnetic nanoparticles could be key to effective immunotherapy
In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use. A summary of the research, conducted in mouse and human...

Great Barrier Reef marine reserves combat coral disease
A new and significant role for marine reserves on the Great Barrier Reef has been revealed, with researchers finding the reserves reduce the prevalence of coral diseases. It's been known for some time that marine reserves are important for maintaining and enhancing fish stocks, but this is the first time marine reserves have been shown to enhance coral health on the Great Barrier Reef. Researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University found that...

Hacking the programs of cancer stem cells
All tumor cells are the offspring of a single, aberrant cell, but they are not all alike. Only a few retain the capacity of the original cell to create an entire tumor.

How our gut changes across the life course
Scientists and clinicians on the Norwich Research Park have carried out the first detailed study of how our intestinal tract changes as we age, and how this determines our overall health. As well as digesting food, the gut plays a central role in programming our immune system, and provides an effective barrier to bacteria that could make us ill. In particular, immune cells that line the gut work to maintain the integrity of the barrier, as well as maintaining a balance that provides a healthy...

Two proteins control the growth of the heart and its adaptation to high blood pressure
Researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have identified how two proteins control the growth of the heart and its adaptation to high blood pressure (hypertension). Lead investigator Dr. Guadalupe Sabio explains that the results, described in Nature Communications, not only increase our understanding of the mechanisms used by cardiac cells to grow and adapt, but could also help in the design of new strategies to treat heart failure caused by...

Two new weapons in the battle against bacteria
Proteins are made up of a chain of amino acids and are vital for all cell processes. Proteases are among the most important types of protein. Like "molecular scissors", they cut other proteins at given positions and thereby execute important cell functions. By cutting the amino acid chains to the right length or breaking proteins apart they, for example, activate or deactivate proteins, decompose defective ones or switch signal sequences that serve to transport proteins to their proper position...

Phages transducing antibiotic resistance detected in chicken meat
Bacteria resistant to antibiotics are on the rise. There are different explanations for how resistances are transferred. Researchers from the Vetmeduni Vienna found phages in chicken meat that are able to transfer antimicrobial resistance to bacteria. Phages are viruses that exclusively infect bacteria. They can contribute to the spread of antimicrobial resistance. The findings may also be relevant for clinical settings. The study was published in the journal Applied and Environmental...

Tracking the viral parasites cruising our waterways
Humans aren't the only ones who like to cruise along the waterways, so do viruses. For the first time, a map of fecal viruses traveling our global waterways has been created using modeling methods to aid in assessing water quality worldwide. "Many countries are at risk of serious public health hazards due to lack of basic sanitation," said Joan Rose, Homer Nowlin Chair in water research at Michigan State University. "With this map, however, we can assess where viruses are being discharged from...
