Hydrogen-making algae's 'Achilles' heel' discovered

(PhysOrg.com) -- Scientists have discovered how oxygen stops green algae from producing hydrogen. The findings could help those working towards 'solar H2-farms' in which microorganisms produce hydrogen fuel from sunlight ...

LANL develops first genetically engineered 'magnetic' algae

LANL scientists have genetically engineered "magnetic" algae to investigate alternative, more efficient harvesting and lipid extraction methods for biofuels. The researchers seek to reduce the cost of algae-based biofuel ...

New biosensor can detect bacteria instantaneously

A research group from the Rovira i Virgili University (URV) in Tarragona, Spain, has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique ...

Hunting for high life: What lives in Earth's stratosphere?

What lives at the edge of space? Other than high-flying jet aircraft pilots (and the occasional daredevil skydiver) you wouldn't expect to find many living things over 10 kilometers up—yet this is exactly where one NASA ...

Tool detects patterns hidden in vast data sets

Researchers from the Broad Institute and Harvard University have developed a tool that can tackle large data sets in a way that no other software program can. Part of a suite of statistical tools called MINE, it can tease ...

Teaching algae to make fuel

Many kinds of algae and cyanobacteria, common water-dwelling microorganisms, are capable of using energy from sunlight to split water molecules and release hydrogen, which holds promise as a clean and carbon-free fuel for ...

Viruses can have immune systems, new research shows

A study published today in the journal Nature reports that a viral predator of the cholera bacteria has stolen the functional immune system of bacteria and is using it against its bacterial host. The study provides the first ...
