Deciphering the olfactory receptor code
In animals, numerous behaviors are governed by the olfactory perception of their surrounding world. Whether originating in the nose of a mammal or the antennas of an insect, perception results from the combined activation of multiple receptors located in these organs. Identifying the full repertoire of receptors stimulated by a given odorant would represent a key step in deciphering the code that mediates these behaviors. To this end, a tool that provides a complete olfactory receptor signature...

New mechanisms of self-organization in living cells
Chromosome is a structure inside the cell nucleus that carries a large part of the genetic information and is responsible for its storage, transfer and implementation. Chromosome is formed from a very long DNA molecule - a double chain of a plurality of genes. Given that the diameter of the cell nucleus is usually around hundredth of a millimeter or even less, while the total length of DNA constituting human genome is about two meters, it is clear that DNA must be packaged very...

'Golden jackals' of East Africa are actually 'golden wolves'
Despite their remarkably similar appearance, the "golden jackals" of East Africa and Eurasia are actually two entirely different species. The discovery, based on DNA evidence and reported in the Cell Press journal Current Biology on July 30, increases the overall biodiversity of the Canidae--the group including dogs, wolves, foxes, and jackals--from 35 living species to 36. "This represents the first discovery of a 'new' canid species in Africa in over 150 years," says Klaus-Peter Koepfli of...

DNA research offers clues on cell mutation
A team of researchers from Colorado State University has been studying DNA damage in living cells to learn more about how genetic abnormalities arise. It has long been known that DNA molecules in every cell get constantly damaged by things from the outside environment, like sunlight, cigarette smoke and radiation. However, more recently researchers have discovered that sources from within the cell itself can sometimes be even more damaging. DNA, or deoxyribonucleic acid, is found in the...

Structure of a hantavirus protein as a promising model for drug design
Bank voles are small rodents that are not dangerous by themselves, but their excreta can contain one of the dangerous hantaviruses. While bank voles are unaffected by the infection, hantaviruses can cause potentially fatal diseases in humans for which no treatments exist. In central and northern Europe, infection is accompanied by fever, headache, or even renal failure. The strain that occurs in East Asia -- the Hantaan virus -- is even more dangerous: up to five percent of infected patients...

Searching for an ancient syphilis DNA in newborns
The ancient bones of newborns are very useful to recover the ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum. This is the conclusion reached by a study led by Universitat Autònoma de Barcelona (UAB), which was able to obtain the genetic material from the bacteria in more than one individual, in what is considered to be the oldest case known to date. Several previous intents had only achieved to yield this material in one occasion and from only one...

'Fourth strand' of European ancestry originated with hunter-gatherers isolated by Ice Age
The first sequencing of ancient genomes extracted from human remains that date back to the Late Upper Palaeolithic period over 13,000 years ago has revealed a previously unknown "fourth strand" of ancient European ancestry. This new lineage stems from populations of hunter-gatherers that split from western hunter-gatherers shortly after the 'out of Africa' expansion some 45,000 years ago and went on to settle in the Caucasus region, where southern Russia meets Georgia today. Here these...

A 'supergene' underlies genetic differences sexual behaviour in male ruff
The ruff is a Eurasian shorebird that has a spectacular lekking behaviour where highly ornamented males compete for females. Now two groups report that males with alternative reproductive strategies carry a chromosomal rearrangement that has been maintained as a balanced genetic polymorphism for about 4 million years. The two studies, one led by scientists at Uppsala university, are published today in Nature Genetics. Three different types of ruff males occur at the leks of this species....

New insights into a virus proteome
The genome encodes the complete information needed by an organism, including that required for protein production. Viruses, which are up to a thousand times smaller than human cells, have considerably smaller genomes.

A key protein is discovered as essential for malaria parasite transmission to mosquitos
Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the only forms that are infectious to mosquitos. The research also gives...

Too much of a good thing: Extra genes make bacteria lethal
We, as most animals, host many different beneficial bacteria. Being beneficial to the host often pays off for the bacteria, as success of the host determines the survival and spread of the microbe. But if bacteria grow too much they may become deadly. In a new study published in the latest edition of the scientific journal PLOS Biology*, a research team from Instituto Gulbenkian de Ciencia (IGC; Portugal) found that a single genomic change can turn beneficial bacteria into pathogenic bacteria,...
