Scientists map key landmarks in human genome

..., allowing the factors to regulate expression of a nearby gene. It has long been assumed that these factors can't bind to a stretch of DNA that is bound by a nucleosome; they can, however, attach to DNA "linkers" between two nucleosomes. With their new method, Fisher's group found that transcription facto...

Beavers helping frogs, toads survive

...oads and 24 times more boreal chorus frogs than on nearby free-flowing streams. The study identifies beaver as a valuable 'surrogate species', said University of Alberta researchers Dr. Cam Stevens (lead author) and Dr. Cindy Paszkowski. The work is published in the January 2007 issue of Biological Conse...

Micro molecules can identify pancreatic cancer

...d human pancreatic tumor tissue and compared it to nearby normal tissue and control tissue for levels of microRNA (miRNA). It identified about 100 different miRNAs that are present usually at very high levels in the tumor tissue compared with their levels in normal pancreatic tissue. The findings suggest ...

Jefferson researchers uncover new way nature turns genes on and off

...so-called maintenance elements, one of which, in a nearby region, bxd, is located between two HOX genes, Ubx and abd-A. Dr. Mazo explains that several "long" ncRNAs are transcribed through bxd maintenance elements. They were thought to be expressed in the same cells as Ubx, and to regulate HOX gene coding s...

In 2004, WCS conservationists working in the Southern Highlands of Tanzania discovered a new species of primate--the kipunji monkey--which in 2006 they described as a new genus as well....

Wolves are suffering less from inbreeding than expected

...l genes are added by introducing a new wolf from a nearby population, the positive effects will be maintained longer than previously estimated. - We think our results are relevant also for other threatened populations of carnivores. Such spe cies require large areas for their territories and most natural r...

Study finds the air rich with bacteria

The team also determined that location was not as strong a source of microbial variation as time and weather. Specifically, the time of the year during ...

Study helps explain why botulinum toxin is so deadly

...out a map can locate an airport by first finding a nearby landmark, like a big river, and then searching for the airport. New research from the University of Wisconsin School of Medicine and Public Health (SMPH) and Scripps Research Institute shows how the astonishingly powerful botulinum toxin uses a simi...

Vanishing beetle horns have surprise function

With the larval horn tissue destroyed, the scientists observed most larvae were unable to break the husks of their larval head capsules, resulting in young adult hatchlings whose heads were tightly (and lethally...

Dernburg and Phillips applied "reverse genetics" to the neighboring genes, obtainin...

Pressured by predators, lizards see rapid shift in natural selection

The scientists kept six other control cays predator-free and exhaustively counted, marked, and measured lizards on all 12 isles. Anolis sagrei spends much of its time on the ground, but previo...

The researchers used the same system to see how the OPCs respond to injuries and conditions like multiple sclerosis. They did so by using a las...

Taking 'chips' to the next level of gene hunting

...pending on where they land, wrongly turn on or off nearby genes, interrupt a gene by lodging in the middle of it, or cause chromosomes to break. Transposable elements long have been suspected of playing a role vital to disease-causing mutations in people. Boeke hopes that the TIP-chip eventually can be used...

As global climate changes occur, "the role of organism temperature in driving species distribution patterns has assumed a further sense of urgency," say the authors.
