Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to program muscle cell alignment, which is strongly tied to healthy muscle function.

The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. Investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.

Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.

Yeast cells are widely used to study G protein-coupled receptors (GPCRs), a large group of cell surface proteins in humans. However, several of these proteins lose their function when introduced into yeast cells. To tackle this issue, researchers developed an innovative strategy to restore GPCR function in yeast cells by inducing random mutations. Their findings can help understand GPCRs better and could pave the way to therapeutic breakthroughs for many diseases.

Using cryo-electron microscopy (cryo-EM), researchers captured unprecedented images of key immune system receptors interacting with messenger proteins, elucidating how the receptors change shape upon activation and transmit signals within the cell. The findings suggest new pathways for developing therapeutic molecules for diseases such as COVID-19, rheumatoid arthritis, neurodegenerative diseases and cancer.

Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments against CMV infections are very limited and can have severe side effects. Researchers now propose a new way to protect against CMV. Instead of targeting the virus, their approach boosts the weak immune system and lets it fight the virus on its own.

The legendary Alexander Fleming, who famously discovered penicillin, once said 'never to neglect an extraordinary appearance or happening.' And the path of science often leads to just that. New research is turning the page in our understanding of harmful bacteria and how they turn on certain genes, causing disease in our bodies.

Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and, important for the understanding of Alzheimer's disease development, generates amyloid beta (Ab)-like peptides, toxic protein fragments from the amyloid precursor protein that are considered to be at the center of the development of Alzheimer's disease.

People overeat and become overweight for a variety of reasons. The fact that flavorful high-calorie food is often available nearly everywhere at any time doesn't help. Researchers have determined for the first time why certain chemicals in cooked or processed foods, called advanced glycation end products, or AGEs, increase hunger and test our willpower or ability to make healthy choices when it comes to food.

The heat shock response of cells is a classic model of biological adaptation, part of the fundamental processes of life -- conserved in creatures from single-celled yeast to humans -- that allow our cells to adjust to changing conditions in their environment. For years, scientists have focused on how different genes respond to heat stress to understand this survival technique. Now, thanks to the innovative use of advanced imaging techniques, researchers are getting an unprecedented look at the inner machinery of cells to see how they respond to heat stress.

One of the building blocks of ocean life can adapt to cope with the effects of climate change, according to new research. The discovery holds promises for biotechnology developments that could counter the negative effects of changing environmental conditions, such as ocean warming and even the reduction in the productivity of crops.

Fecal microbe transplants from healthy donors can treat patients with recurrent Clostridium difficile infections. However, after tens of thousands transplants, little was known about which donor strains provide long-term engraftment, and which engraft early after the transplant. Most failures of fecal microbe transplantation occur in the first four weeks. Researchers have now found 19 Bacteroides vulgatus genes that were unique to three strains that show early engraftment in patients after a fecal transplant, as opposed to seven strains that did not show early engraftment.

To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.
