A bitter taste in the mouth is often a symptom or side effect of illness, which may be the result of how the body reacts to pathogens. A new study sheds light on the mechanisms involved in the complex interplay between taste perception and immune function. Their work also highlights the potential of a sequencing tool for investigating epigenetic mechanisms that affect taste-cell gene expression.

Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal relationship hints at an evolutionary transition towards mutualistic symbiosis.

Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution.

A new powerful antibiotic, isolated from bacteria that could not be studied before, seems capable of combating harmful bacteria and even multi-resistant 'superbugs'. Named Clovibactin, the antibiotic appears to kill bacteria in an unusual way, making it more difficult for bacteria to develop any resistance against it.

Researchers have discovered how high-fat diets can change gut bacteria and alter digestive molecules called bile acids that are modified by those bacteria, predisposing mice to colorectal cancer. The findings bring scientists closer to understanding the causes of and how to prevent colorectal cancer.

Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of the nuclear membrane. The microscopic force sensor, only about 0.00002 mm long, is constructed of exotic ingredients such as spider web protein parts, fluorescent proteins from jellyfish, and antibodies from alpaca. In addition, the multidisciplinary team of researchers has developed further the sensitivity of super-resolution microscopy technique.

Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers come to this conclusion on the basis of studies on cell cultures.

A single injection of a novel CRISPR gene-editing treatment safely and efficiently removes SIV -- a virus related to the AIDS-causing agent HIV -- from the genomes of non-human primates, scientists now report. The groundbreaking work complements previous experiments as the basis for the first-ever clinical trial of an HIV gene-editing technology in human patients, which was authorized by the Food and Drug Administration (FDA) in 2022.

Early social and environmental exposures can have large and lasting effects on child development and adult health. One of the systems that is vulnerable to external influence is the gut microbiome. A new study highlights a critical development window during which racial differences in the gut microbiome emerge. The findings are based on analysis of data from 2,756 gut microbiome samples from 729 U.S. children between birth and 12 years of age.

Cooking food thoroughly and avoiding some types of vegetables and salad during a course of antibiotic treatment could potentially reduce antibiotic resistance, by preventing bacteria carrying resistance genes getting into the gut, according to a new study.

Researchers have found that molecules in vegetables like broccoli or cauliflower help to maintain a healthy barrier in the lung and ease infection.

'Back-to-school' season means buying pens, figuring out the bus route, and ... earaches. Cutting corners with antibiotics, however, can accelerate resistance. Today, researchers report developing a single-use nanoscale system that's unlikely to generate resistance. Using a compound similar to bleach in test animals, they show it can kill off a bacterium that causes ear infections, and it could someday be easily applied as a gel.

Young vegetables known as microgreens are reputed to be particularly good for health. But are microgreens the superfood they're claimed to be, and how do they compare to mature veggies? Scientists have found that their nutritional profiles differ, as do their effects on gut bacteria. Yet, tests in mice suggest that both microgreen and mature vegetables can limit weight gain.
