Researchers find 24 species believed new to science in Suriname rainforest

...limate change. The burgeoning global carbon market creates new economic value for carbon stored in standing rainforest, providing fresh incentive for developing nations such as Suriname to avoid deforestation....

Brightening prospects of using fluorescent nanotubes in medical applications

... The methods researchers use to produce nanotubes creates soot that contains a number of different types of nanotubes: metallic, semiconducting, double-walled, single-walled, etc. Of these, only the single-walled semiconducting nanotubes, or SWNTs, are capable of producing light. Metallic nanotubes actually...

Gene mutation linked to cognition is found only in humans

...ich also demonstrated the molecular mechanism that creates this novel protein, will be published online in Human Mutation, the official journal of the Human Genome Variation Society. The journal is available online via Wiley InterScience at http://www.interscience.wiley.com/journal/humanmutation . Led by D...

Scientists identify prion's infectious secret

...e." In many organisms, this conformational cascade creates long fibers called amyloids. (The brains of animals that have died from prion infections are literally packed with amyloid clumps.) In order to glean insights into the mechanics that enable amyloid formation, Peter Tessier, a postdoctoral scienti...

'Short-circuit' found in ocean circulation

...g across and rapid movement along density surfaces creates a 'short-circuit' in the overturning circulation, meaning it is more concentrated in this part of the Southern Ocean. The researchers made use of a unique signal - the spread of helium released naturally from the Earth’s interior at deep vents in...

Scientists see DNA get 'sunburned' for the first time

...sting. Scientists also believe that chronic damage creates mutations that lead to diseases such as skin cancer. For this study, the chemists used a technique called transient absorption to observe the DNA damage. Transient absorption is based on the idea that molecules absorb light at specific wavelengths...

Woven scaffolds could improve cartilage repair

...Moutos developed adds a third set of fibers, which creates a three-dimensional product. Also, since the scaffold is a woven material, there are tiny spaces where cartilage cells can nestle and grow. ...

3-D ultrasound identifies women at risk for impending preterm birth

...pulation at risk," they said. The current study creates the basis for further prospective studies to confirm that 3-dimensional ultrasound assessment of the fetal adrenal gland volume can assist clinicians with devising better therapeutic and preventive interventions for preterm birth....

Cold sore virus might play role in Alzheimer's disease

...lar form of the gene that puts people at risk also creates a fertile environment for herpes in the brain, allowing the virus to be more active than other forms of the ApoE gene permit. Scientists have known for more than 15 years that the ApoE-4 gene is a player in Alzheimer's disease, but the idea that i...

Microbes start immune response by sneaking inside cells

...he cell is what triggers the immune response. That creates a new perspective for developing new drugs,?says s...rchers discovered that a protein called pannexin-1 creates the pore, like a devious undersea diver drilling a hole in a ship hull. The team’s work joins a g...

MU researcher placing eye implants in cats to help humans see

... inside the back part of the eyeball, Narfstrom creates a small blister in the retina and a small opening, large enough for the microchip, which is just two millimeters in diameter and 23 micrometers (one-millionth of a meter) thick. The chip includes several thousand microphotodiodes that react to light ...

Researchers discover gene crucial for nerve cell insulation

...c Potential By understanding the process which creates myelin, researchers may now be able to investigate new therapies for disorders affecting myelin. "Our research has uncovered a whole new mechanism for regulating myelin genes," said Dr. Svaren. "Our hope is to exploit this knowledge so that we ca...

Scientists find potential 'off-switch' for HIV virus

...ons that runs in a loop. First, one of HIV's genes creates the Tat protein, which is part of the chemical sig...rotein into a message that activates the virus and creates more Tat protein, and eventually converts the T cell into an active HIV factory. "The more of th...

Study to explore using magnets to correct 'sunken chest'

...s coupled with a second one outside the chest that creates a steady, controlled, outward pull on the internal magnet to reshape the bone, cartilage and chest wall. The procedure marks one of the first times magnets have been embedded inside the body to treat a health condition, according to Michael Harri...

Einstein's tea leaves inspire new blood separation technique

...epel the oppositely charged ions close to it. This creates an airflow known as "ionic wind" that sweeps across the surface of the blood, causing it to circulate. The microscopic particles in the blood travel in a downward spiral because of the needle's angle relative to the surface. When the fluid begins t...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

...nol. Then the beads are coated with a polymer that creates a hydrophilic surface on the beads. This allows the beads to be functionalized by adding antibodies or DNA molecules to the surface that will capture the target molecules. These beads are dual-function -- both optical and magnetic -- but according...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...absorption spectroscopy, where a pulsed laser beam creates a brief absorption in a sample gas, which in turn creates a very small acoustic signal. A miniature quartz tuning fork acts as a "microphone" to record the re...

Triplex assay used to assay duplex genomic DNA

... It is surmised that specific third strand binding creates additional grooves into which additional YOYO-1 molecules intercalate. "We have decided not to focus on improving probe chemistry at this time, but rather to develop a flow injection based instrument which is matched to our chemistry," continued D...
