Using genetic engineering to study evolutionary assimilation of foreign DNA in a new host

All life is subject to evolution in the form of mutations that change the DNA sequence of an organism's offspring, after which natural selection allows the 'fittest' mutants to survive and pass on their genes to future generations.

Researchers describe a previously unknown phylum of aquatic Archaea

In a publication in Nature Communications last Friday, NIOZ scientists Nina Dombrowski and Anja Spang and their collaboration partners describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.

Synthetic peptide makes multidrug-resistant bacteria sensitive to antibiotics

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a synthetic peptide that can make multidrug-resistant bacteria sensitive to antibiotics again when used together with traditional antibiotics, offering hope for the prospect of a combination treatment strategy to tackle certain antibiotic-tolerant infections.

Rutgers expert highlights the effects of climate change on allergies, autoimmunity and the microbiome

Climate change and disruption of the ecosystem have the potential to profoundly impact the human body. Xue Ming, professor of neurology at Rutgers New Jersey Medical School, who recently published a paper in the International Journal of Environmental Research and Public Health on the effects of climate change on allergies, autoimmunity and the microbiome -- the beneficial microorganisms that live on and inside the human body -- discusses how the delicate balance of the environment affects conditions such as allergies, autism and immune disorders.
