Researchers reveal bacteria can generate electricity from methane

A groundbreaking study has revealed the critical role of gut bacteria in regulating stress responses through interactions with the body's circadian rhythms.

Columbia researchers developed probiotic bacteria that train the immune system to eliminate cancer cells, paving the way for a new class of cancer vaccinations that take advantage of bacteria's innate tumour-targeting abilities. These microbial cancer vaccines can be tailored to each person's specific original tumour and metastases, perhaps preventing future recurrences.

Endosymbiosis is a remarkable biological phenomenon in which one creature resides within another. Such an unconventional partnership is usually advantageous to both parties. Even in human bodies, we find evidence of such cohabitation: mitochondria, the cells' powerhouses, originated from an ancient endosymbiosis. Bacteria long ago invaded and colonized other cells. This coexistence created the groundwork for mitochondria, which are found in the cells of plants, animals, and fungi.

Researchers at Virginia Tech have discovered how bacteria change molecules in order to infect their host.

According to a recent study, older persons who reported consuming more ultra-processed foods were nearly 10 per cent more likely to die after a median follow-up of 23 years than older adults who reported consuming less processed food.

In a new study, individuals' levels of refined carbohydrate consumption were statistically connected to their facial attractiveness as evaluated by heterosexual volunteers of the opposite sex.

We know that greenhouse gas emissions, such as carbon dioxide, should increase rainfall. The emissions warm the atmosphere, resulting in a one-two punch: warmer oceans make it easier for water to evaporate, and warmer air can store more water vapour, allowing more moisture to fall as rain. However, for long of the twentieth century, the data did not clearly reveal a rise in precipitation.

Researchers have developed an antibiotic that could provide a new tool in the fight against drug-resistant bacteria and the illnesses they cause.

One of the most significant cells in the body is the macrophage. This immune cell, dubbed "big eater" in Greek, eats and breaks down dangerous substances like dust, debris, bacteria, and cancer cells. Macrophages play a particularly important role in the lungs, where they combat bacterial infections and remove excess surfactant, a lipid- and protein-rich covering that is essential for lung health but can accumulate sticky matter if left unchecked.

Researchers have identified a microscopic worm species that infects and kills insects.
