15-year hunt finds cause of pseudothalidomide syndrome

...g that the two copies are lined up together at the center of the dividing cell. Once lined up, tiny molecular "motors" attach to the centromere of each copy and pull the original and the new copy away from each another as division proceeds. However, in cells from people with Roberts syndrome, the chromosom...

NHGRI targets 12 more organisms for genome sequencing

.... Louis. Assignment of each organism to a specific center or centers will be determined at a later date. NHGRI's selection process begins with two working groups comprised of experts from across the research community. Each of the working groups is responsible for developing a proposal for a set of genomes...

Insects, viruses could hold key for better human teamwork in disasters

...laboration during disaster relief efforts. At the center of the scientists' sights are a sub-group of their own species -- specifically, civil engineers, who historically have had a limited role in such efforts, especially those involving critical physical infrastructures. Supported by a five-year $2.37 m...

Scientists analyze chromosomes 2 and 4

...he chromosome's DNA sequence for the relics of the center (centromere) of the ape chromosome that was inactivated upon fusion with the other ape chromosome. They subsequently identified a 36,000 base pair stretch of DNA sequence that likely marks the precise location of the inactived centromere. That tract ...

Penn Researchers Use Robotic Surgery

... with three multi-jointed arms; a computer command center several feet from the patient, where the doctor sits, and a 3-D computer monitor similar to a "viewfinder" that affords a magnified view of the surgical site inside the patient. Equipped with a special, double-telescopic endoscope, the viewfinder all...

Alcohol consumption disrupts breastfeeding hormones

...ars, Monell has been the nation's leading research center focused on understanding the senses of smell, taste and chemical irritation: how they function and affect our lives, from before birth through old age. Using a multidisciplinary approach, scientists collaborate in the areas of: sensation and percepti...

Two new retroviruses—transmitted from animals—identified

Depression gene may weaken mood-regulating circuit

... the brain and the cingulate, an emotion-dampening center located near the front of the brain, were playing a duet under the baton of the depression-linked gene. The gene codes for the serotonin transporter, the protein in brain cells that recycles the chemical messenger after it's been secreted into the s...

Bioinformatics reveals new gene regulation system

...fand, director of the IITP's research and training center of bioinformatics. "It's a proof of principle that you can go a very long way by comparative genomics now." Their findings will be published in the July issue of Trends in Genetics, with early publication now online. Gelfand is presenting the work on...

Motor transport in bio-nano systems

...llular traffic: some vesicles travel from the cell center to the periphery and vice versa, some shuttle between different organelles or cellular compartments. An extreme case is provided by the long-ranged transport of vesicles and organelles along the axons between our nerve cells, which can be as long as ...

Study shows humans have ability to track odors, much like bloodhounds

...f the primary olfactory cortex - the brain's smell center - devoted to them, indicating that the brain at least encodes information that could help it localize an odor. A successful detection of an odor is accompanied by more activity in the region of the olfactory cortex associated with the particular nost...

New tool reveals secrets of migrating cells

...sis starts with immature T cells moving out of the center of the thymus, the medulla, to the very outside edge of the cortex, where they proliferate and fill up the cortex. At this point, Witt said, they undergo the first of two tests to see if their surface receptors (called T cell receptors) work properly...

Stem Cells Found In Cerebellum; Possible Cell of Origin for Childhood Brain Tumors

... gone awry. The cerebellum is the brain's control center for motor coordination and cognitive function, yet little has been known about the origins of the neurons and supporting "glial" cells that populate this region. The Duke discovery of stem cells in the cerebellum suggests a possible origin for these...

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

Using NCSA's Xeon system, a state-of-the-art parallel computer called Tungsten, the researchers were able to complete the required computational runs in about 15 hours, from midnight on Sept....

Virologist finds contagious equine flu in dogs

...r minds," said Ed Dubovi, director of the virology center at Cornell's Animal Health Diagnostic Laboratory, who isolated the virus from the University of Florida samples. Still, he added, there is no evidence of the virus jumping to humans, and there is no expectation of it doing so. It is possible the eq...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

...he human or monkey test subjects' attention to the center of a computer screen by showing them a yellow square. The subjects would then be shown either another square or an image of a monkey looking either left or right. Immediately after that, the face would disappear and to the left or right on the screen...

Duke Experiments Boost Radiation's Cancer-Killing Effects

...no overall inhibition of tumor growth. The tumor's center became "necrotic" or populated with dead cells, but the perimeter of the tumor continued to grow. In fact, blocking HIF-1 before radiation was detrimental to radiation's effects: it prevented cancer cells from engaging in the very behaviors that rad...
