Molecular Genealogy in the Arctic Sediment

(PhysOrg.com) -- Heat-loving bacteria found in the Arctic seabed have their origins in oil springs and the depths of the Earth's crust. This is the finding of a project supported by the Austrian Science Fund FWF, which used ...

Warm-blooded dinosaurs worked up a sweat

(PhysOrg.com) -- Were dinosaurs endothermic (warm-blooded) like present-day mammals and birds or ectothermic (cold-blooded) like present-day lizards? The implications of this simple-sounding question go beyond deciding whether ...

'Fatostatin' is a turnoff for fat genes

A small molecule earlier found to have both anti-fat and anti-cancer abilities works as a literal turnoff for fat-making genes, according to a new report in the August 28th issue of the journal Chemistry and Biology, a Cell ...

Joint research into an enzyme that causes genetic diseases

Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the ...

Super-sleepers could help super-sizers!

Burrowing frogs can survive buried for several years without food or water. Scientists have discovered that the metabolism of their cells changes radically during the dormancy period allowing the frogs to maximize the use ...

Toward a systems biology map of iron metabolism

Scientists at the Wake Forest University School of Medicine, the University of Manchester in the United Kingdom, and the Virginia Bioinformatics Institute at Virginia Tech have taken the first steps toward constructing a ...

Reversing ecology reveals ancient environments

From hair color to the ancestral line of parasitic bacteria, scientists can glean a lot from genes. But imagine if genes also revealed where you lived or who you spent time with. It turns out they do, if you know where and ...
