Microbial communities are thought to contain keystone species, which can disproportionately affect the stability of the communities, even if only present in low abundances. Identifying these keystone species can be challenging, especially in the human gut

Some patients with myelodysplastic syndromes, like acute myeloid leukemia, benefit from a chemotherapy drug called decitabine that stunts cancer growth. But many others are resistant to decatibine's effects or become resistant over time. Wilmot Cancer In

University of B.C. researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe.

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic had declined by 10% during

Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.

Researchers at the University of Tsukuba have rediscovered and successfully cultivating Rhabdamoeba marina -- a rare marine amoeba that has only been reported in two cases in the past century. Using this culture strain, they performed a comprehen

Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. In a recently published study led by the University of Hawai'i at Manoa, research

Unlike humans, zebrafish can completely regenerate their hearts after injury. They owe this ability to the interaction between their nervous and immune systems, as researchers led by Suphansa Sawamiphak from the Max Delbrück Center now report in the

Old people who follow a Mediterranean diet are at a lower risk of cognitive decline, according to a study published in the journal Molecular Nutrition and Food Research. The study provides new evidence for a better understanding of the biological

For over 20 years, a research team at Lund University in Sweden has studied the common bluetail damselfly. Females occur in three different colour forms -- one with a male-like appearance, something that protects them from mating harassment. In a new stud

Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. The team present the half-s

The vision system, evolved over millions of years, is highly complex. To make vision sensitive throughout the whole range of visible wavelengths, Nature employs a supramolecular chemistry approach. The visual pigment, cis-retinal, changes its sha
