Human knowledge is based upon directed connectivity between brain areas

...r bird, familiar or unfamiliar humans are used to classify objects in the world around them and group them into categories that have been formed and shaped constantly through every day's experience. Categorization during visual perception is exceptionally fast. Within just a fraction of a second we effortles...

Reconstructing the biology of extinct species: A new approach

...rsonal knowledge or film of animals in the wild to classify species into one of six locomotor categories ranging from very slow and deliberate to fast and agile. The scientists then compared the canal size of each species to its category of movement. The results revealed a highly significant statistical re...

ENCODE map changes view of the human genome landscape

...developed and employed a computational approach to classify genomic regions as active or repressed. Remarkably, they found that the pattern of active versus repressed domains was strikingly conserved between different cell types, and thus may be a universal feature of human genome architecture. For over ...

New algorithms classify outcomes of nonsmall cell lung cancer patients

Smithsonian scientists discover new marine species in eastern Pacific

...ture during the next several years, as taxonomists classify each organism. This adventure is far from over. The STRI team is ideally positioned to thoroughly sample the entire fauna, not just the corals and fishes. Since most studies of the Eastern Pacific date back 100 years, it is vital to obtain current ...

2-step process filters evolution of genes of human and chimpanzee

... needed to decouple the two steps of evolution and classify mutations into many different kinds." The researchers used the very large survey of human genetic variation called HapMap for their analysis, which compared human variations with the chimpanzee genome. They focused their analysis on the simplest a...

Technology captures tumors' genetic profile, guides cancer treatment

...d whether it actually improves doctors' ability to classify and treat individual tumors. "We've shown the practical potential of this technique," observed Garraway, who is also an instructor in medicine at Harvard Medical School. "It is a step toward the day when cancer patients will routinely have their tu...

Investigating the invisible life in our environment
