The researchers mapped out each person's CD36 gene variations, then compared those results with the presence of known heart...Researchers probe marine mysteries off the Alaskan coast

They charted new canyons and features of this previously unexplored, remote region of the world. Using...Vollum Institute discovery may unlock human genome
...thod uncovered about 6,300 regulatory regions that mapped to distinct sites on the genome. "A subset of these regions highlight novel genes," said Impey, assistant professor of neurology, OHSU School of Medicine, and the study's lead author. Goodman calls the process "the most comprehensive analysis to date...Scientists find that the human nose is more complicated than a jumbo jet
...not simply laminar or turbulent." The research has mapped the flow of air around anatomical landmarks in the nose, such as the conchae and has discovered why we need to breathe deeply to smell a flower. Our sense of smell relies on a sample of air reaching the olfactory bulb at the top of the nose and that ...Found: Missing sequence of the human Y chromosome

Interestingly, they found that c-Myb is not required for every step of hematopoiesis or for every type of blood cell. Instead, c-Myb is critical for very distin...Family trees of ancient bacteria reveal evolutionary moves

Cyanobacteria emerging some two billion years ago were becoming complex microbes that had larger cell diameters than earlier groups at least 2.5 microns. ...New dinosaur raptor found; First in Southern Hemisphere
...new raptor. Because fossils dont preserve DNA, Pol mapped the dinosaurs anatomical and skeletal characteristics to place it on the raptor family tree.

...mpensate. More than 300 diseases already have been mapped to the X chromosome, and though the X chromosome contains only 4 percent of all human genes, it accounts for almost 10 percent of inherited diseases caused by a single gene, which doctors often refer to as Mendelian disorders. These "X-linked" disord...New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

The tumor cells block the flow of water, so as those cells die, water diffusion changes. In the study of 20 people with malignant brain tumors, the researchers found that any ch...U of T researchers map role of Epstein-Barr virus in cancer
Researchers at the University of Toronto have mapped the molecular details that show how a viral protein coded in the Epstein-Barr virus immortalizes cells and causes them to continuously grow, thereby predisposing people to certain types of cancer. "Epstein-Barr virus (EBV) is one of the most common h...Satellite maps will ease plight of endangered mountain gorillas

They report changes in the ebb and flow of glaciers, in meters per year, over five-year intervals. "This is a unique glacier archive.

A team of marine scientists has mapped the undersea journeys of Atlantic bluefin tuna and concluded that tighter restrictions should be placed on commercial fishing to protect the feeding and breeding grounds of this top migratory predator--one of the most commercially valuable fish in th...Biologists determine genetic blueprint of social amoeba

"We don't know what that logic is, but it seems as if it has something to do with the molecular features of the odorant."
