U. of Colorado researchers hunting down, studying new microorganisms

...novel technique that extracts DNA from the soil to pinpoint the new groups of microbes and polymerase chain reaction, or PCR, to amplify and identify them, providing a snapshot of the microscopic diversity in the high alpine region, he said. "A major thrust of the new grant is to attempt to grow some of the...

Infectious disease expert warns of spread of Rocky Mountain spotted fever

...ppear until later in the infection and resembles a pinpoint pattern of pink-to-red spots over the entire body, or parts thereof. The rash is also noticeable on the soles of the feet and palms of the hands, where rashes do not usually appear. At this later stage of infection, antibiotic therapy becomes somew...

Immune system's distress signal tells bacteria when to strike back

...in a few days. Alverdy and colleagues were able to pinpoint key early steps of this lethal process. The transformation starts when a weakened host tries to boost its defenses against any possible invasion. The host's T cells release chemical signals that activate the immune system. One of those signals, int...

Researchers pinpoint genes that drive spread of breast cancer to lungs

.... "In essence, we used a mouse as a cell sorter to pinpoint the cancer cells," said Massagu. Once they had isolated the aggressive metastatic cells, the researchers then analyzed the activity of the cells' genes using DNA microarrays -- which are capable of measuring the activity of a vast number of genes at ...

Gene's mutations found to cause life-threatening aortic disease

...ntinues to scrutinize a stretch of chromosome 5 to pinpoint another genetic variation that they earlier mapped to that area of the genome. Researchers elsewhere have mapped two other genetic variations affecting single families to chromosomes 11 and 16. Milewicz also is on the faculty of the UT Graduate Sc...

Brain size may depend upon how neural cells are cleaved

...discovered, said Tsai, further studies will try to pinpoint how its signaling determines the orientation of spindles during mitosis, and thus the orientation of cell cleavage. "While this is basic research, we do know that this mechanism is very important in determining the ultimate size of the brain," said T...

The synapse is a shotgun

...aly at the receptor level, but it is impossible to pinpoint the problem with existing techniques. With our modeling technique, we can explore the detailed geometry of the damaged tissue and ask how much of that anomaly is caused by the geometry itself," he said. "Once we have pinned down where the real proble...

Naturally occurring asbestos linked to lung cancer

...isticated geographic information system mapping to pinpoint home or street addresses for every diagnosed individual. A map from the California Department of Conservation, Division of Mines and Geology, served as the reference for ultramafic rock deposits. Finally, statistical adjustments were made for sex, oc...

Ancient diets of Australian birds point to big ecosystem changes

... arrived. The analyses, which scientists used to pinpoint particular plant groups ingested by the birds, indicated that emus living before 50,000 years ago preferred nutritious grasses characteristic of milder temperatures and warm summer rains, Miller said. After 45,000 years ago, the eggshell evidence sh...

The Academy of Natural Sciences & team discover new catfish species

...-resolution computer images allowed researchers to pinpoint key differences from other species in the bone structure of the skull, the shape of the air bladder and the articulation of a barbel (the part that resembles a cat's whisker). Studies also show the fish is the only member of an ancient group that may...

Scientists create artificial cricket hairs

...specific neural cells, which allows the cricket to pinpoint low-frequency sound from any given direction by using the combined neural information from all the sensory hairs on the cerci. Physicists at the University of Twente in the Netherlands have now succeeded in building artificial sensory hair systems, w...

APNS sees abnormal cell division as possible precursor of Alzheimer's disease

...ural death. In this study, researchers set out to pinpoint the other reasons neurons were dying. In a study of mice genetically engineered to develop neurofibrillary tangles, they observed that neurons abnormally expressed cell cycle proteins, which are a prerequisite to cell division. This process does no...

Researchers track down cause of a disfiguring bone disorder

... on and off. Today's study is one of the first to pinpoint a disease-associated mutation that alters one of these long-range regulatory elements. "Our study addresses a fundamental issue with regard to the majority of the human genome that is noncoding in nature, and its potential impact on human health," Lo...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...arget. Also, existing drugs can be re-evaluated to pinpoint at what stage they actually work, to fine-tune their activity." The experimental set-up for this study was devised by Young and Melikyan last year to investigate viral infection in a manner as close to 'real life' as possible. The researchers filmed ...

FSU meteorologists' work may lead to better tracking of hurricanes

...came very clear. Because forecasters always try to pinpoint the eye of the hurricane, this knowledge will help with locating a storm's exact position and possibly lead to better tracking. The National Oceanic and Atmospheric Administration's National Hurricane Center (NHC) is the agency that issues hurricane ...

World Ocean Day: How satellites safeguard our waters

Identifying oil spills For detecting oil pollution, radar sensors such as Envisat's Advanced Synthetic Aperture Radar (ASAR) are effective. Oil has a dampening...

Study: 'homemade' gene expression technology unreliable

...thousands of genes at once, scientists can quickly pinpoint genes affected by drugs being tested to treat heart disease, mental illness, infectious diseases and cancer. In the past, researchers were only able to analyze a few genes at once, and they were often uncertain whether these were of greatest importan...

Fibromyalgia patients may benefit from cough remedy, UF study finds

...h now," he said. Future UF studies will attempt to pinpoint where the pain impulses are originating. In the current study, researchers worked with 14 women with fibromyalgia and 10 women who did not have the disease, using mechanical devices that tapped the participants' hands repeatedly. One part of the stud...

Two pioneers in genetic research win $250,000 March of Dimes prize

...mes. "Before gene targeting, researchers could not pinpoint how a specific gene worked, which was very frustrating," said Dr. Jennifer L. Howse, president of the March of Dimes. "Dr. Capecchi and Dr. Smithies, working independently, made a technological breakthrough that completely revolutionized biomedical ...
