New study of the world's smallest elephant

The world's smallest elephant species, the newly described Bornean elephant, will be the focus of a Cardiff University study in Sabah, Malaysia for the next three years. The Bornean elephant has recently been confirmed as a separate sub-species, dramatically increasing its importance for biodiver...

How the neuron sprouts its branches

...ble for receiving, sorting and shipping cargoes of newly synthesized molecules needed for cell growth and function. Until the new findings, researchers believed that only a central Golgi apparatus played a role in such distribution, said Ehlers. "In most mammalian cells, the Golgi has a very stereotyped s...

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

A newly identified gene expression profile could help predict how patients with advanced ovarian cancer will respond to chemotherapy treatment. Described in a study in the November 1, 2005 issue of The Journal of Clinical Oncology (JCO), the new findings fur...

Penn researchers study the use of ultrasound for treatment of cancer

... ultrasound because we observed that some of these newly formed vessels created by tumors are very weak in nature, and if you turn on low-intensity ultrasound vibrations you can disrupt the blood flow through these vessels," explained Andrew Wood, DVSc, PhD, a co-investigator of the study and based in the ...

In SAD patients, autumn antidepressants can prevent winter depression

...ssive disorder," says Dr. Rosenthal, author of the newly revised Winter Blues: Seasonal Affective Disorder: What It Is and How to Overcome It (Guilford Publications, 2005). "The strategy makes sense when dealing with a condition where the pattern of relapse is somewhat predictable and the symptoms being p...

Jefferson scientists identify gene defect leading to abnormal skin development and cancer

.... The GLFC is eager to use a synthetic form of the newly found pheromone to replace the poison by luring lamprey to traps and sterilizing the males, the researchers said. Using the pheromone would be environmentally friendly and less expensive. "The GLFC has the goal of controlling lamprey with a new and...

Leading lampreys to slaughter: Pheromone for scourge of Great Lakes identified

.... The GLFC is eager to use a synthetic form of the newly found pheromone to replace the poison by luring lamprey to traps and sterilizing the males, the researchers said. Using the pheromone would be environmentally friendly and less expensive. "The GLFC has the goal of controlling lamprey with a new and...

Phenotype is influenced by nature, nurture and noise

...ioengineering professor Jeff Hasty reported that a newly developed computer model shows that a combination of unscripted biochemical variations, or noise, leads to oscillations in gene regulation that couldn't otherwise be predicted. Such noise is routinely described by cell biologists who record large phe...

Neurons generated in the adult brain learn to respond to novel stimuli

Novel protein complex enables survival in hostile environment

...hanoarchaeon Methanocaldococcus jannaschii". "The newly discovered enzyme links biological methanogenesis and sulfate reduction, two most ancient respiratory metabolisms, in a unique way," said Mukhopadhyay, whose lab studies organisms that produce methane, in particular M. jannaschii. Commenting on the ...

Zooming in on the protein-conducting channel

Deep treasure to be found in Oculina Bank

...edition's goals is to "ground truth," or verify, a newly produced high-resolution multibeam sonar map of the region, which offers unprecedented resolution to reveal bottom features that were previously indistinguishable. The team will explore various areas using the ROV to compare observations with what ap...

NIAID researchers show how promising TB drug works

...ur PA-824-resistant mutant strains: two lacked the newly described M. tb protein altogether, while the remaining two mutants evidently acquired resistance to PA-824 through a mutation that made the protein unable to bind to the drug, Dr. Barry says. With the discovery of the specific protein that interact...

Sickle cell disease corrected in human models using stem cell-based gene therapy

...ells from SCD patients, researchers found that the newly formed red blood cells made normal hemoglobin and suppressed production of the sickle shaped hemoglobin typical of the disease. "Sickle cell disease can only be cured by transplanting healthy blood-forming stem cells from another individual, but thi...

Natural compound from 'pond scum' shows potential activity against Alzheimer's

...to moderate forms of the disease, experts say. The newly isolated compound, nostocarboline, was shown to be a potent inhibitor of cholinesterase -- a brain chemical thought to be important for memory and thinking -- whose breakdown has been associated with the disease's progression. The natural compound's ...

Einstein scientists discover how protein crucial for motion is synthesised at the right place in the cell

...protrusions. The team's previous work showed how newly formed actin messenger RNA molecules find their way to the cell's periphery: A protein called ZBP1 binds to the messenger RNA and "escorts" it out of the fibroblast nucleus and into the cytoplasm. On reaching the cell's periphery, the messenger RNA i...

Sudden change in social status triggers genetic response in male fish, study finds

...'s the top fish now and will vigorously defend his newly acquired breeding grounds. "We found that when the dominating male is removed, the subordinate male perceives an opportunity to advance in social status and responds both behaviorally and by turning on genes that ultimately make him capable of repr...

Tropical dry forests receive international recognition

...e that. Sanchez-Azofeifa is the director of the newly formed TROPI-DRY, a research network on tropical dry forests housed in the Faculty of Science. The Inter American Institute for Global Change Research has just funded the network to the tune of US$2.7 million for the U of A and all the contributing L...

Solexa and collaborating scientists illuminate the small RNA component of the transcriptome

The newly discovered small RNAs that match to genes are exciting, but so are those that derive from relatively featureless regions between genes," added Pamela J. Green, a professor at the University of Delaware and the Delaware Biotechnology Institute, anothe...

K-State professors discover enzyme responsible for creation of a beetle's hard shell

...." When the laccase-2 gene was not expressed, the newly formed cuticle remained soft and white instead of becoming hard and dark-colored. These results indicated which protein was responsible for the hard shell's formation, Kanost said. The identification of laccase-2 as the catalyst for cuticle tanning ...
