Carnegie Mellon University research reveals how cells process large genes

...exons. Lopez's team developed molecular tools to analyze the lariats released from any intron during splicing in vivo. In his analyses, he found that the production of recursive lariats greatly exceeded that of direct lariats, indicating that recursive splicing is the predominant processing pathway for lon...

UNC computer, marine scientists collaborate to predict flow of toxic waters from Katrina

...nded their work with RENCI, Reed and colleagues to analyze various aspects of last weekend's Hurricane Rita and its effects in Texas and Louisiana. "We are trying to be prepared and generate reliable information that the hazardous materials experts will need to have," said CSDL scientist Jesse Feynen. "We'r...

New technique rapidly detects illness-causing bacteria

...to determine a source quickly. It may also help to analyze a throat culture swab, to tell if someone has an illness like strep throat. "We hope to see this technique commercialized, because it is very rapid compared to all the standard methods right now," said Nugen, the study's lead author. Nugen conducted...

Sleeping beauty plays a significant role in identifying cancer genes

...eland and their colleagues will be to generate and analyze a large number of other tumors induced in mice using the Sleeping Beauty jumping gene. Largaespada and his team will focus on identifying genes causing prostate, lung and colorectal cancer; Jenkins and her team will study genes for tumors in the brai...

Unweaving amyloid fibers to solve prion puzzles

...tead used a combination of low resolution tools to analyze varieties of prion strains and piece together the puzzle of how amyloids form. "We now have an overall picture of how prions join together to form the amyloid's molecular structure," says Lindquist, who also is a professor of biology at MIT. Prions...

New technique may speed DNA analysis

...de. Scientists use DNA microarrays to discover and analyze a person's DNA or messenger-RNA genetic code. This allows for, say, the early diagnosis of liver cancer, or the prediction of the chances that a couple will produce a child with a genetic disease. Frequent, widespread use of these devices is hindere...

Ancient DNA confirms single origin of Malagasy primates

Yale biologists have managed to extract and analyze DNA from giant, extinct lemurs, according to a Yale study published in a recent issue of the Proceedings of the National Academy of Sciences. Radiocarbon dating of the bones and teeth from which the DNA was obtained reveal that each of the individua...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

...y of California-San Diego conducted brain scans to analyze structural volume changes in 103 adults divided among four populations: methamphetamine abusers who were HIV-positive; methamphetamine abusers who were HIV-negative; nonabusers who were HIV-positive; and nonabusers who were HIV-negative. They also as...

"You put the specimen in and the microscope is programmed to step down at fine intervals, perform its series of scans, and collect 3D coord...

Purdue's gold nanorods brighten future for medical imaging

...anced medical imaging techniques that use light to analyze blood vessels and underlying tissues. "One obstacle is that light in the visible spectrum does not pass through tissue very well," said Alexander Wei, an associate professor of chemistry who worked with Cheng and other Purdue researchers, including ...

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

KU scientists will test the strength of the synthetic cross-linked biopolymers tha...

Researchers find Amchitka seafood safe for now

...Complicated Data One of CRESP's challenges was to analyze biological samples for a long enough time to know what levels of radionuclides were actually there (since some radionuclides are present in any marine system). It had then to distinguish whether what it did find might have come from the nuclear tests...
