Protecting biocatalysts from oxygen

Certain enzymes from bacteria and algae can produce molecular hydrogen from protons and electrons—an energy carrier on which many hopes are riding. All they need for this purpose is light energy. The major obstacle to their ...

Researchers compile world's first 'atlas' of airborne microbes

Bacteria are truly abundant across the Earth's surface, from the soil to the oceans. The microbial population of the air that surrounds us is comparatively unknown, but a research expedition led by PolyU scientists is about ...

World's simplest animals get their place in the tree of life

The group with the world's simplest animals—tiny blob-like life forms with no organs and just a few cell types—finally has a fleshed-out family tree built by a research group led by the American Museum of Natural History, ...

Why synonymous mutations are not always silent

New modeling shows how synonymous mutations—those that change the DNA sequence of a gene but not the sequence of the encoded protein—can still impact protein production and function. A team of researchers led by Penn ...

You are 'what you eat,' but you are not 'where you live'

Genetic studies of the past 20 years have extensively shown how, across human populations worldwide, the majority of genetic differences are encountered at the individual rather than at the population level. Two random humans ...

DNA reveals the past and future of coral reefs

New DNA techniques are being used to understand how coral reacted to the end of the last ice age in order to better predict how they will cope with current changes to the climate.

How cells turn independent and regulate functions

With his thesis, Jacob Lewerentz, Department of Molecular Biology at Umeå University, contributes to the knowledge about how cells regulate their protein level and adapt to a new milieu outside their organism. He has also ...
