Of lice and men

...consistent with the well-known phenomenon that any single species or lineage of lice (like other parasites) tends to stick only to one species of host and rarely jumps to other hosts. Scientists already knew that early ancestors of our species, Homo sapiens, diverged from other archaic humans about 1...

Talented sniffer: A receptor known for guiding sperm to egg plays a role in the nose

...r findings, the authors propose a model in which a single receptor protein helps perform diverse chemosensory functions in the nose as well as in sperm. It is tempting to speculate that in the future, "sniffing tests" could be employed as a diagnostic tool for fertility defects associated with olfactory rec...

Head lice reveal contact between modern and ancient humans

... evolutionary histories on the back (or head) of a single host. More likely, the New World louse evolved on an archaic form of humans and subsequently transferred to a modern version. The split between modern humans ( Homo sapiens ) and one of our archaic forerunners, Homo erectus , took place about 1....

NIH funds first nationaL SNP genotyping center at Broad Institute

...ommon type of variation in the human genome is the single nucleotide polymorphism, or SNP (pronounced "snip"). A SNP is a single DNA base pair, or unit of DNA, the sequence of which can vary from individual to individual. It is ...

Protein energy profiles offer clues about amyloids

...f the chemical interactions that take place when a single protein folds itself into its characteristic shape. Despite this mystery and complexity, Clementi and colleagues believe they are creating a statistical method that will help scientists predict which proteins are prone to misfold. "In designing a com...

University of Oregon professor wins 2004 Spiers Medal

"Quantum dots have novel properties, including improved brightness, resistance against photobleaching, and multicolor light emission. The larger size of the quantum dots also provides enough surface area for linking to ...

Interactive health information system to detect Japanese encephalitis in Asia

... All reported information will enter a single database. Health officials will log into the system via the web and can use the system's analytic tools to evaluate trends, identify outbreaks, and immediately deploy appropriate resources. "This solution will break new ground in p...

New technique targets pesticide-resistant insects

...eliver the enzyme inhibitor and the pesticide in a single dose. Firstly, an insect's resistance mechanisms are deactivated and then, four to five hours later, the insect is exposed to the pesticide. Dr Gunning said the technology had been found to be effective in some of the world's resistance 'hot spots'. ...
