Researchers have shed new light on the ancient relationship between moss and fungi. They discovered that intricate moss-fungi interactions often depended on a third variable -- the presence of endobacteria within the fungi themselves.

Researchers have made a groundbreaking discovery: a new cell that remembers allergies.

Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.

Researchers say hydroquinine could be an effective naturally occurring disinfecting solution for contact lenses and help combat keratitis infections.

The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.

Bacteria in the mouth may play a role in survival from idiopathic pulmonary fibrosis (IPF), finds a new study.

New research reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures.

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.

A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

A research group explored how the social evolution of microbes can be manipulated by tuning the physical parameters of the environment in which they live.

Researchers have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes.

Researchers studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton that is closely related to Hemimastigophora, a group of organisms considered to be one of the deepest branches of eukaryotes.

Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.

Influenza A viruses with induced resistance to a new candidate antiviral drug were found to be impaired in cell culture and weakened in animals, according to a new study.

Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.
