UN development work guided from space

...n Affairs) is using space-derived relief data that identifies areas most at risk of landslides to plan safe urban expansion. And by using GIS tools to combine a satellite image of newly built-up areas with local data on the limits of the local water supply, zones most at risk of disease are highlighted for att...

Newly invented Endometrial Function Test (EFT®) solves the puzzle of unexplained infertility

...July issue of the journal Fertility and Sterility, identifies two new biochemical markers, cyclin E and p27, that more accurately assess endometrial health compared to the routine examination that is done by pathology laboratories. "These findings will help women who have difficulty conceiving become pregnant a...

...g-sensitive and -resistant bacteria and ultimately identifies the drug concentration necessary to suppress a resistant mutant population. Directly applicable to a clinical setting, the model would allow easy determination of the antibiotic dose required to treat infection and also suppress the development of an...

Helping coral reefs survive climate change

...ar the damaged reefs. A new study of these patches identifies factors likely to protect these threatened marine ecosystems during climate change. "As baseline sea surface temperatures continue to rise, climate change may represent the single greatest threat to coral reefs worldwide," say Jordan West of the U.S...

ES cell model could provide clues to causes, cures for diabetes

...his model based on mouse embryonic stem cells that identifies their differentiation into pancreatic precursor cells and islet cell types, says Odorico, "should provide a valuable tool to study normal islet and pancreatic development. One could potentially use this model to identify novel genes and learn how isl...

First structure of transporter enzyme family is solved

...edded in the cell membrane. "Only when the enzyme identifies lactose does the other gate, connected to the inside of the cell, open and let the sugar go through. This process is driven by energy called the 'proton motive force' and should be common among membrane transport proteins." Professor Iwata added: "O...

Dual discoveries in genetic processing improve accuracy of genome information

...een species," said Reenan. The signature reliably identifies genes that are recoded during transcription, providing scientists with a means to predict the occurrence of editing. "Being able to predict editing sites is a revolutionary discovery that will greatly increase the value of existing genome sequences...

Stem-cell defect underlies common genetic disorder

...ly about half the cases," said Morrison. "Our work identifies new genes whose mutations might underlie the disease. We've found the mechanism by which one type of mutation impairs the function of the neural crest stem cells that give rise to the enteric nervous system." The researchers began by conducting a glo...

Scientists identify new sperm protein required for fertilization

..., a study published in the August 22 issue of Cell identifies a new protein that is required for a sperm to bind to an egg during the process of fertilization. This research provides important new insight into the molecular mechanisms that are involved in the initial events of sperm-egg association and may she...

Study at TSRI links dozens of proteins to several rare muscle and nerve degeneration diseases

...ponent parts) with tandem mass spectrometry (which identifies the components based on their masses). The instrument detects these masses and uses sophisticated software to identify thousands of separate proteins. But MudPIT alone was not enough in this case, because the inner nuclear membrane is in contact wi...

Molecule found to be critical for kidney development

...put together." Using an antibody that specifically identifies the active form of Notch, Kopan's group observed that the protein is extremely active in the kidney at an earlier stage than previously thought. So they teamed up with kidney development expert Jeffrey H. Miner, Ph.D., associate professor of medicine...

Fruit fly pheromone receptor first ever discovered linked to specific sexual behavior

...itical for mating, Amrein explained. First, a male identifies a female visually. The male then approaches the female and touches her with his forelegs -- which contain one of the flies' taste organs -- in a behavior known as tapping. After detecting pheromones from the female, the male produces a courtship song...

National lab trains U. S. customs agents against WMD

The U.S. border inspector training classes are modeled after a training program targeted to inspectors from other countries called INTERDICT/RADACAD, for Interdiction of Materials and...

Danger on chromosome 15

...ution and Prader-Willi and Angelman syndromes, and identifies four new genes named NIPA1, NIPA2, CYFIPI, and GCP5 in the most unstable part of chromosome 15. The second paper details how researchers linked a mutation in NIPA1 to families with hereditary spastic paraplegia. "What we see here is two very impo...

Researchers discover new genetic link to common colon cancer

... National Academy of Sciences (PNAS article #2286) identifies a specific stretch of DNA on chromosome 9 that houses a "susceptibility" gene. "Previous studies have shown that colon cancer risk can be inherited," says Sanford Markowitz, MD, principal investigator for the study. "By analyzing blood samples from...

Common genetic damages in non-dividing cells lead to the creation of mutant proteins

...genetic damages are capable of causing TM, it also identifies specific components of the cellular machinery whose job it is to repair damage from uracil and 8-oxoguanine to prevent TM from occurring," Dr. Doetsch explains. "The extent to which TM might occur for different kinds of genetic damages will depend o...

Heintz also added a reporter gene to the BACs so that cells with the selected gene activity glow bright green. Many new brain cell types or subtypes have been discovered...

Ethical guidelines needed before 'nutrigenomic' groceries come to market

Who should have access to nutritional genomics information, who should not, and how should improper access be prevented? How should nutritional g...
