Study: Predatory dinosaurs had bird-like pulmonary system

...ismic and evolutionary biology last month and will join the faculty at the College of the Holy Cross in Worcester, Mass., this fall. In birds, this special anatomical configuration increases the gas exchange potential within the lungs, boosting metabolism and creating warm-bloodedness. The researchers ar...

Purdue scientists may have found key to halting spinal cord damage

...ified, drugs that counter acrolein's effects could join the other approaches to treating spinal cord injury under development at Purdue's Center for Paralysis Research. "My colleague Richard Borgens and I have already had our hands in developing PEG, a substance that coats damaged spinal cells so that th...

Discovery of an American salamander where it shouldn't be: Korea

...current Nature paper, though Karsen elected not to join them in order to accept their offer to name it after him. To date, Wake and his American colleagues have seen only one live specimen and a few preserved specimens, though Vieites is scheduled to travel to Korea in May to scout the area, which is hea...

Unusual antibiotics show promise against deadly 'superbugs'

... Exactly how and why the collagen and the peptides join is uncertain. But researchers know that collagen molecules form a distinctive triple-helix in which three long protein strands intertwine like rope. Yu speculates that because the smaller collagen mimetic peptides have a propensity to make similar tr...

Modified collagen could yield important medical applications

But researchers know that collagen molecules form a distinctive triple-helix in which three long protein strands intertwine like rope.

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

... DNA technology utilizes a series of procedures to join (recombine) segments of two or more different DNA molecules. When put into cell culture, a recombinant DNA molecule multiplies itself to form a colony of daughter cells that secretes the desired protein. These cells become "factories" for the product...

Researchers discover key gene involved in bark beetle pheromone production

... few hours do they fly from one tree to another to join other bark beetles, mate and start a new life cycle. But other bark beetles know where to locate mates because they are responding to an "aggregation" pheromone. If this pheromone could be disrupted, the beetles wouldn't be able to organize a "mass ...

New miniaturised chip dramatically reduces time taken for DNA analysis

...some of the DNA fragments from the bacterial cells join the complementing fragments from the probe, creating a measurable electrical current. The sensor converts this current into a signal that can be seen by the person controlling the tests, making him aware there are bacteria. Also, because the sensors ...

Scientists use manufacturing methods to reconstruct mastodon

... on whose property it was discovered in 1998, will join the museum's female mastodon skeleton, which has been on display since the 1940s. Paleontologists rarely find complete skeletons, so they're often faced with the task of creating realistic substitutes for the missing bones. Incomplete skeletons are ...

Next Generation Body Scanner Launched By The University Of Manchester

...in imaging for patients." The new 3T scanner will join the University's other magnetic resonance research scanner a 1.5 Tesla Philips Intera scanner based at the Wellcome Trust Clinical Research Facility on the University campus. The human MRI research programme is overseen by the University's Faculty o...

The biggest family tree ever

...s the first time members of the general public can join a genetics project of this scale. Michael F. Hamm...he actual work load will depend on how many people join in the multi-national effort. "For the first time people all around the world can learn about their...

New tumor-suppressor gene discovered

...ted that the two protein products of the two genes join structurally at the molecular level to form a larger, more powerful, and more productive protein complex. Because of its far-reaching implications, this study is expected to establish a new area of research that is likely to engage scientists workin...

Multiple Campylobacter Genomes Sequenced

... Guillain-Barré syndrome, in which the nerves that join the spinal cord and brain to the rest of the body are damaged, sometimes permanently. Campylobacteriosis is usually caused by C. jejuni, a spiral-shaped bacterium normally found in cattle, swine, and birds, where it causes no problems. But the illne...

Affymetrix and Stratagene Announce Strategic Software Alliance

...enomic studies. In addition, we're very excited to join Affymetrix' consortium of developers in an effort to bring to market breakthrough gene expression microarray technology. By partnering with other thought leaders in our field, we believe we have the opportunity to position our technology as a standar...

An HIV Protein Plays a Surprising Role in Gene Activation

... transcribes protein-coding genes. RNA polymerases join with so-called general transcription factors to form a pre-initiation complex (PIC) on the gene's promoter, where it binds to region rich in thymine (T) and adenine (A) named the TATA box. The first transcription factor to associate with the TATA box...

Growth in the sea comes down to a struggle for iron

...erry collaborates on the project but was unable to join the trip. Also participating were professors Charles Trick of the University of Western Ontario and William Cochlan at San Francisco State University, along with their graduate students. Several members of the Japanese research team were onboard the...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

...at varies the brightness of a light. Co-activators join with other regulatory proteins called transcription factors in controlling the expression of genes. Spiegelman and Jiandie Lin, PhD, the paper's lead author and a researcher at Dana-Farber, have previously discovered the PGC-1 co-activator family and...

Bioartificial kidney under study at MCG
