Study dusts sugar coating off little-known regulation in cells
In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically ...

'Dark matter' of the genome revealed through analysis of 29 mammals
An international team of researchers has discovered the vast majority of the so-called "dark matter" in the human genome, by means of a sweeping comparison of 29 mammalian genomes. The team, led by scientists from the Broad ...

Breeding with Neanderthals appears to have helped early humans fight disease
(PhysOrg.com) -- Following up on evidence that Homo Sapiens and Neanderthals mated and produced offspring, following the sequencing of the Neanderthal genome last year, Peter Parham, professor of microbiology ...
A knockout resource for mouse genetics
An international consortium of researchers report today in Nature that they have knocked out almost 40 per cent of the genes in the mouse genome. The completed resource will power studies of gene activity in models of hum ...

Genetic sequencing alone doesn't offer a true picture of human disease
Despite what you might have heard, genetic sequencing alone is not enough to understand human disease. Researchers at Duke University Medical Center have shown that functional tests are absolutely necessary to understand ...

Fossil finger bone yields genome of a previously unknown human relative (w/ Video)
(PhysOrg.com) -- A 30,000-year-old finger bone found in a cave in southern Siberia came from a young girl who was neither an early modern human nor a Neanderthal, but belonged to a previously unknown group ...

Analysis of teeth suggests modern humans mature more slowly than Neanderthals did
A sophisticated new examination of teeth from 11 Neanderthal and early human fossils shows that modern humans are slower than our ancestors to reach full maturity. The finding suggests that our characteristically ...

Dormant ancient chimp virus revived
(PhysOrg.com) -- Researchers in New York have identified the receptor of an ancient chimpanzee retrovirus that has been dormant for at least a million years. Now the scientists have resurrected a key part of the virus to ...
Complete Neanderthal genome yields insights into human evolution and evidence of interbreeding
After extracting ancient DNA from the 40,000-year-old bones of Neanderthals, scientists have obtained a draft sequence of the Neanderthal genome, yielding important new insights into the evolution of modern ...

Neanderthals may have interbred with humans twice
(PhysOrg.com) -- Extinct human species such as Neanderthals may still be with us, at least in our DNA, and this may help explain why they disappeared from the fossil record around 30,000 years ago.
Human genome
The human genome is the genome of Homo sapiens, which is stored on 23 chromosome pairs. Twenty-two of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs. The Human Genome Project (HGP) produced a reference sequence of the euchromatic human genome, which is used worldwide in biomedical sciences.
The haploid human genome contains an estimated 20,000–25,000 protein-coding genes, far fewer than had been expected before its sequencing. In fact, only about 1.5% of the genome codes for proteins, while the rest consists of RNA genes, regulatory sequences, introns and (controversially) "junk" DNA.
