Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging.

Using a technique that has shown promise in targeting cancer tumors, a team has found a way to deploy a molecular warhead that can annihilate the bacterium that causes Lyme disease.

Scientists have published the first successful application of 2-photon intravital microscopy (IVM) to image the dynamics of fungal infections in the kidney of a living host. The study reveals that the opportunistic human fungal pathogen Candida albicans requires the ability to metabolize proline, an amino acid obtained from the host, to mount virulent infections.

An international team of researchers has discovered that formaldehyde, a widely spread pollutant and common metabolite in our body, interferes in the epigenetic programming of the cell. This finding expands the knowledge of formaldehyde, previously considered only as a DNA mutagen, and helps establishing a further link with cancer.

Researchers found that the hormone oxytocin, known to be involved in regulating feeding and social behavior and until now to be produced mostly in the brain, is also produced in the human intestine. Furthermore, gut resident bacteria L. reuteri can affect the production of gut-made oxytocin, providing the first insights into a mechanism by which these bacteria can influence human health.

In the immune system's fight against cancer and infections, the T cells often lose their power. Now immunologists may have found a possible explanation for this phenomenon.

Our understanding of how cells recycle lipids through autophagy -- a form of cellular degradation -- has grown significantly, thanks to a recent study. Using yeast as a model organism, the researchers explored the molecular mechanisms leading to the degradation of the phospholipid bilayers making up the cell membranes. Their findings improve our understanding of cellular degradation processes and related metabolic disorders.

Mountains of used plastic bottles get thrown away every day, but microbes could potentially tackle this problem. Now, researchers report that they've developed a plastic-eating E. coli that can efficiently turn polyethylene terephthalate (PET) waste into adipic acid, which is used to make nylon materials, drugs and fragrances.

Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely resemble those in humans. The Telomouse model, developed by incorporating a genetic variation from a mouse species with naturally shorter telomeres, provides a valuable resource for in-depth aging and cancer research. This discovery promises to reveal new insights into the genetics of aging and may contribute to enhanced longevity and well-being.

Dendritic cells are immune cells that capture and present antigens to T cells, activating an immune response. Researchers have discovered that short-chain fatty acids produced by intestinal bacteria regulate a crucial step in this process, the extension of dendritic 'arms.' This breakthrough finding could potentially lead to the development of disease prevention strategies involving beneficial bacteria and new drugs targeting the regulation of dendritic cell function.

Organoids help researchers understand biological processes in health and in disease. It is, however, difficult to influence the way in which they organize themselves into complex tissues. Now a group has found a new way to do so.

A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.

Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers.

Researchers have uncovered that proteins use a common chemical label as a shield to protect them from degradation, which in turn affects motility and aging.

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
