Drug resistance testing in treatment-naive HIV patients is cost-effective

...gradually increased. "We're hoping that this study makes it part of standard care," said Dr. Sax. ...

Researchers at UGA provide first look at protein expression in Chagas disease-causing parasites

...sed contact surface. This reduced contact surface makes it harder for barnacles to attach, and reduces fouling by 67%. When applied to the ship hull, this artificial surface enables ships to ´self-clean´, and a speed of 4-5 knots would remove all organisms attached with little adhesion. Until recently, p...

Nanowires can detect molecular signs of cancer, scientists find

...eases like cancer, for which disease heterogeneity makes tests of single markers inadequate. Patterns of multiple cancer markers might, however, provide the information necessary for robust diagnosis of disease ?[and] detection of markers associated with different stages of disease pathogenesis could furth...

Discovery suggests why stem cells run through stop signs

...ew. "This latest discovery with stem cell division makes us wonder if microRNAs also control division of other types of cells such as cancer cells." Other authors on the Nature paper are Kenji Nakahara of Northwestern University and Karin Fischer, Steve Hatfield and Halyna Shcherbata of the University of ...

Envisat and ERS-2 reveal hidden side of Hurricane Rita

...ut also direction across the water surface. What makes ERS-2's scatterometer especially valuable is that its C-band radar frequency is almost unaffected by heavy rain, so it can return useful wind data even from the heart of the fiercest storms ?and is the sole scatterometer of this type currently in orb...

MERIS monitoring tracks planetary photosynthesis levels

...ocessing power, but ESRIN's Grid-On-Demand service makes it feasible. Grid computing takes its name and organising principle from the electricity grid: anything one computer can do, a pool of computers can do faster and better. These machines do not have to be in the same building, country or even conti...

Proposal would allow wild animals to roam North America

...any gaps developed in the web of interactions that makes up a healthy ecosystem. Introducing living counterparts to the extinct Pleistocene-period animals could fill the voids for American plants and animals that coevolved with large but now extinct mammals in the picture, the researchers said. For examp...

UF researchers kill resistant bugs one bandage at a time

Once given 'no respect,' cells' tiny RNAS take driver's seat

...oRNAs are made by the same cellular machinery that makes other forms of RNA -- like the messenger RNA used to build proteins. However, microRNAs are immediately processed by cellular machinery that deals with what is known as RNA interference -- a biological phenomenon that specifically prevents RNA from b...

Unweaving amyloid fibers to solve prion puzzles

...on, amyloids are also unusually robust, which also makes them attractive for nano devices. The advantage of the yeast protein is that it is not toxic, even for yeast. ...

Geckos: It's not always about sex

...d with Autumn at Lewis & Clark College. "This makes them a bit like mules, which are a cross between a horse and a donkey," said Kearney. "Mules are very robust animals, but they cannot reproduce." Kearney's research suggested that the hybrid forms of Bynoe's geckos could not only reproduce through pa...

New technique may speed DNA analysis

...mble along a pattern composed of DNA strands. This makes SuNS a versatile technology that could be used to produce other complex nano-devices currently manufactured slowly and expensively: micro- and nano-fluidics channels, single-electron transistors, optical biosensors and metallic wires, to name a few. ...

NHGRI Selects 13 More Organisms for Genome Sequencing

...it contains many chromosomal rearrangements, which makes it valuable for studying how such rearrangements have contributed to the evolution and speciation of humans and other non-human primates. To identify chromosomal rearrangements, researchers will need to sequence only small portions of the gibbon geno...

Possible treatment found for 'chemobrain'

Pollution-eating bacteria produce electricity

...sing simple sugars or organic waste products. What makes Milliken's and May's discovery so unique is the bacterium itself. It is the member of a genus known as Desulfitobacterium, which up until now was not known to have the capacity to generate electricity. These bacteria are most commonly known for their...

Use of high hydrostatic pressure to inactivate Hepatitis A virus in oysters studied

...tributors, as well as public health officials. HPP makes it possible to eradicate or inactivate pathogens while still delivering a 'raw' product to the consumer. The study will benefit processors and distributors by mitigating their food safety liability, but most importantly, also will help protect consu...

Simple explanation for complex pattern of feather development

... that cause things to develop -- an activator that makes things happen, and an inhibitor that suppresses the activator. To test the model in feathers, Harris forced expression of the activator, Shh, or the inhibitor, Bmp2, in the skin of six-day old chick embryos by injecting them with a retrovirus. The r...
