Major obesity gene is 'lost in the shuffle'

...ws that during the evolution of gibbons, these Alu elements lined up and recombined with each other, erasing approximately 100 kilobases of DNA that spanned the ASIP gene." Ranging in size from 15 to 22 pounds, gibbons possess lithe, slender bodies that enable them to swing agilely across branches and vine...

Knowledge of infection may prevent spread of herpes virus

...iral therapy and condom use as the other necessary elements to control the spread of genital herpes nationwide. This most recent study also found that most people who transmitted HSV did not know that they had genital herpes. Wald, Hook, and Leone suggest that physicians should not only increase testing for ...

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...er they are infected or not," said Germann. Other elements of randomness modify the simulated disease course. A significant fraction of infected people (33 percent in the present model) never develop clinical symptoms, although they are themselves infectious. In addition, the durations of the incubation and...

Anti-inflammatory drug's potentially deadly side effect found to be rare

...the other studies of natalizumab will be important elements in "lively" discussions to be held by the Food and Drug Administration regarding the future of this therapy. "Patients with MS are eager to access more effective therapy," he says. "But regulators, physicians and patients alike will first have to w...

New crop of technology reveals plant health

...useful." The sensors and transmitters are two key elements of the system, but its heart is the management software, designed by Computer Technology Institute, Greece, that gathers, and then acts, on the data operating as a plant/environmental context management system. Called ePlantOS, it can control the dep...

Study finds 60 new genes controlled by DNA snippet

...terested in defining as many functional regulatory elements as we can to help geneticists pinpoint a growing number of disease-causing mutations." Study Details In Miano's study, the regulatory sequence under examination was the CArG box. The nucleotide building blocks of DNA chains may contain any one of ...

Salmonella bacteria use RNA to assess and adjust magnesium levels

... the journal Cell, responds to magnesium ions, key elements in the stability of cell membranes and reactants in an energy-making process that fuels most cells. "Magnesium ions are essential to the stability of several different critical processes and structures in the cell, so there has to be a fairly intri...

ASU researchers find link between social behavior, maternal traits in bees

...ancestors. Amdam's research supports the idea that elements of the reproductive behavior of those ancestors evolved to form a basis for social living and divisions of labor. This insight provides evidence for how complex social behavior evolves--evidence that could have value for studies of social behavior i...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

...cation and affiliative bonding behaviors. Both are elements involved in the age-old human social expression of dancing. The genetic evidence was corroborated by two questionnaires distributed by the researchers to the dancers. One is the Tellegen Absorption Scale (TAS), that correlates aspects of spirituali...

Where 'jumping genes' fear to tread

... are conspicuously devoid of ubiquitous mobile DNA elements called transposons. The locations of these region...content in the human genome. These mobile genetic elements are scattered throughout the human genome ?separated, on average, by only 500 base pairs. But Dr. J...

A bathroom that cleans itself

...odifying titanium dioxide nanoparticles with other elements such as iron and nitrogen so they can absorb light at longer wavelengths. Lab trials show that glass coated with the new nanoparticles can be activated by visible light from a lamp to kill Escherchia coli. "If you've got this on tiles or shower scr...

Relationship of brain and skull more than just packaging

...s with evolutionary history a reduction in cranial elements and coincident changes in the shape of the skull and brain. The researchers believe that studying craniosynostosis could shed light on the joint evolution of the brain and skull. The two types of craniosynostosis the researchers studied were early c...

Novel method reveals how menthol discovery could point towards new or improved pain therapies

...s yielded significant insights into the functional elements of TRPM8 ion channel protein that would have been difficult to obtain using other mutagenesis methods." Because the methodology can be used to screen for activation or inhibition, Bandell added, it could prove to be useful as a general method to a...

Polymer aids in blood clotting, pointing way to new treatment

...otozoa of tropical diseases and the blood-clotting elements of human blood." Although no longer at Illinois, Docampo said he's thrilled that the research will be continuing through the Carver grant to the U. of I. "It's theoretically possible to use this discovery to find ways to help the body's own blood-cl...

Report finds cruise industry is protecting the precious places it visits

...and indigenous people in order to include cultural elements in their shore excursions; implement standard operating procedures to ensure minimal negative impact on the local environment and cultures; and educate tourists about specific local regulations, laws, customs and needs. The cruise industry has grow...

Cracking the genetic code for control of gene expression

...e researchers showed that the predicted regulatory elements direct organ-specific expression of a marker gene ...methods enabled genome-wide analysis of regulatory elements in several species. Studying the control of gene expression is a growing area of research at the m...

Scientists develop a way to make the deadliest toxin known even more toxic

...lular catalysts, breaking up proteins into smaller elements such as amino acids and reducing the amount of energy needed for the activation. The study was released in an advanced online version by the Journal of the American Chemical Society. Kim Janda, currently the Ely R. Callaway Jr. professor of chemi...

UF researchers develop ways to keep the bloom on the rose

...ill buy flowers more often, which will benefit all elements of the floral industry. "Our whole business relies on the feelings flowers give to people," said Charles Kremp, owner of Kremp Florists in Philadelphia. "It is important for flowers to arrive to retailers looking their best and to remain looking goo...

Multi-million pound UK Biobank underway

... don't have a clear picture of how these different elements interact. By being so large and detailed, UK Biobank will be able to study many different risk factors together, each of which may have only modest effects on the likelihood of getting some particular disease." Taking part will involve the first vol...

Wisconsin scientists find a way to make human collagen in the lab

...precisely manipulate the lengthy molecules and add elements to collagen that confer new abilities. "We can make collagen that duplicates nature exactly, but we can diverge from that when it is desirable," says Ronald T. Raines, a UW-Madison professor of biochemistry who, with postdoctoral fellow Frank W. Kot...
