Reversal of role for a viral protein associated with the development of lymphoma

...ons) that lie between long stretches of non-coding elements (introns). During processing, introns are snipped out and exons pasted together to form a template for proteins called messenger RNA (mRNA). Mistakes in RNA processing can reduce the expression of a functional protein or, worse, produce an abnormal p...

New Scripps Oceanography project to study sediments and ecosystem restoration in Venice lagoon

...iment research group) will dissect and analyze key elements of Venice Lagoon's sediment through a program integrating geochemical, physical, microbial, toxicological and ecological science. This multidisciplinary approach, the project's leaders say, will provide valuable data about the lagoon and the dynamics...

'Jumping genes' contribute to the uniqueness of individual brains

...cess of creating diversity with the help of mobile elements and then selecting for the fittest is restricted t...eless gibberish or "junk" DNA, the transposable L1 elements were thought to be intracellular parasites or leftovers from our distant evolutionary past. It has ...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'

...n of the opioid system was correlated with various elements of the experience of pain. For example, activity in the dorsolateral prefrontal cortex was associated with the expectation of pain relief reported by the volunteers. In other areas, that activation was associated with relief of the intensity of pai...

...etics. The former included our use of transposable elements or 'jumping genes'--discovered at Cold Spring Harbor by [Nobel laureate] Barbara McClintock--to 'tag' the ramosa1 gene. That enabled us to isolate the gene and determine its DNA sequence for a variety of other experiments." "As corn was being domest...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

... hydrogen peroxide. Its "green" design is based on elements used naturally in biochemistry. Fe-TAMLs were discovered by Collins, whose group has developed an extensive suite of these catalysts to provide clean, safe alternatives to existing industrial practices, as well as ways to remediate other pressing pro...

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...caused by rain and vibrations caused by snakes are elements of the temporal pattern," she says. "Snake bites, in general, last longer than raindrops, and the spaces between snake bites are generally longer than the spaces between raindrops." To test the hypothesis that embryos use these features of vibration...

Some studies show that circulating stem cells are capable of diffentiating into other types of tissue, including lung tissue, Zander said, and this study provides evidence of differentiation. Researchers examined lung biopsy specimens from...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

...tein's 326 amino acids in hopes of eliminating the elements that suppressed the immune response but retaining enough of the normal protein's structure to generate protective antibodies. Out of 11 altered versions they found one that met both criteria. In mouse and human macrophages, version rV10, missing ami...

UN: World in big ecological mess

...in any other period, some 60 per cent of ecosystem elements supporting life on Earth, such as fresh water, clean air or a relatively stable climate, are being degraded or used unsustainably, and the situation could become significantly worse during the first half of this century, according to the study. "Onl...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

...rogram on bioinformatics predictions of regulatory elements in genomes is being conducted at NYU's Center for Comparative Functional Genomics, where the focus of the research programs is to combine genomic approaches with developmental genetics and evolution to understand how changes in genomes give rise to t...

Scientists identify genes responsible for 'black rot' disease in vegetables

...veral genes located on strain-specific chromosomal elements that were unique to each strain. In addition, there were dramatic differences in the genomic arrangement of the two strains; the scientists identified significant rearrangements between the genomes, including major translocations, inversions, inserti...
