Novel protein complex enables survival in hostile environment

...t produces methane, an energy resource and a green house gas. Sulfate reduction is also a microbial process where organisms turn sulfate into sulfide, a corrosive compound or gas that smells like rotten eggs. Methanogenesis is a 2.7?.2-billion-year-old process and sulfate reduction originated at least 3.7...

Missing fossil link 'Dallasaurus' found

...an." The Late Cretaceous period was a time of hot house temperatures and rising sea levels. "As the earth warmed and the seas rose, small land-dwelling lizards took to the oceans and developed increasing levels of seagoing capabilities, and over 30 million years, eventually evolving into the top predator...

Expert dispels bird flu paranoia

...m people wanting to know if they should sell their house because their neighbours have got birds. Some ways that bird owners can minimise risk are: Build pens to keep domesticated poultry away from wild birds. Stop domesticated poultry from accessing open ponds, lakes or creeks.

Plants, too, have ways to manage freeloaders

...od at sharing nitrogen, but remain small when they house bacteria that are not. The finding illustrates the complex symbiotic relationships that have evolved between organisms, ranging from one-sided parasitism to mutualism, a situation in which both parties benefit. It also suggests that agricultural pr...

Engineers discover why toucan beaks are models of lightweight strength

...cture with very little additional weight." Like a house covered by a shingled roof, the foam is covered with overlapping keratin tiles, each about 50 micrometers in diameter and 1 micrometer thick, which are glued together to produce sheets. The study in Acta Materialia also noted a hollow region extendi...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...te. "The goal is to create a community resource to house all metagenomic data that will facilitate and advance knowledge of marine microbial ecology, other natural environments, and evolutionary biology." The CAMERA project builds on pioneering efforts in metagenomics to sequence the genomes of entire mi...

Flu not the only germ threat this time of year

...e, looking to land in your eyes or nose and set up house inside your body. And those are just the respiratory germs ?never mind Strep in the throat and ears, or Norwalk viral agents that attack the GI system, and so on.

Evolutionary shifts in olfactory sensitivities in fruit flies

...hat olfactory hairs (sensilla) on the antenna that house receptor neurons specific to the MeHex odor have become three times more numerous, and one hundred times more sensitive, in D. sechellia than in the sibling species D. melanogaster. In parallel, a specific brain area (a so-called olfactory glomerulus...

Study reveals classic symbiotic relationship between ants, bacteria

...relationship. The researchers found that the ants house the bacteria in specialized, highly adapted cavities and nourish them with glandular secretions-an indication that the ants, bacteria, fungus and parasites have likely been evolving together for tens of millions of years. "Every ant species [that we...

Memory loss affects more of the brain than previously thought

A short distance separates the outer membrane and the rest of the organism. How the bacteria maintain their barrier when it's physically rem...

Wild vs. lab rodent comparison supports hygiene hypothesis

The strength of this model, Parker said, is that it takes into account the totality of the animals living in their natural environment. Specifically, the team focused the animals' production of vario...

Allergy battle could be won in five years, says scientist

...f the lungs," he said. "Allergens from pollen or house dust mites are inhaled and then dissolve the binding material between the cells that form these protective linings; they can then enter the body by passing between the cells to cause an allergic response. "The drugs we are developing -- called Alle...

Large-scale genomics project will hunt genes behind common childhood diseases
