Remote control flies? Fly behavior controlled by laser light

...ording to a new report in the 8 April issue of the journal Cell. Susana Lima and Gero Miesenböck hope that the remote control system will provide a valuable way to study how nerve-cell activity and connections are related to specific behaviors, from simple movements to more complex behaviors like learning, ...

Research shows smoking adds a decade to reproductive age of IVF patients

...7 April) in Europe's leading reproductive medicine journal Human Reproduction[1]. Lead researcher Dr Bea Lintsen, from Radboud University Nijmegen Medical Centre, said: "The positive news from our results, however, is that they suggest that couples ?in particular, women with unexplained subfertility ?may be...

Scientists analyze chromosomes 2 and 4

... In a study published in the April 7 issue of the journal Nature, a multi-institution team, led by Washington University School of Medicine in St Louis, described its analysis of the high quality, reference sequence of chromosomes 2 and 4. The sequencing work on the chromosomes was carried out as part of th...

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...These findings, published today in the Open Access journal Reproductive Biology and Endocrinology, offer important new strategies for use in in vitro fertilization and stem cell research, and cast doubt on the established dogma on the fetal origin of eggs in adult human ovaries. It is now well established t...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...ator Award, which recognizes the best paper in the journal Metabolic Engineering. Funded by the National Science Foundation and the National Institutes of Health, Kao's research uses a "reverse engineering" strategy to learn from and exploit drug-company mutants--in this case the bacterial species that prod...

Embryonic Stem Cells Treated With Growth Factor Reverse Hemophilia In Mice: UNC Researchers

... study shows. A report of the study appears in the journal Proceedings of the National Academy of Sciences today (Feb. 15). The genetically altered mice lack the clotting substance factor IX, which in humans results in the hereditary bleeding disorder known as hemophilia B. This disease, much less common th...

While on trail of dioxin, scientists pinpoint cancer target of green tea

Mutation in clams protects against paralytic shellfish poisoning but raises human health risk

... discovery is reported in the April 7 issue of the journal Nature. The authors suggest that it has wide ranging implications for the evolution of shellfish in the presence of toxic algae and increases the risk of PSP to people who eat clams by enabling contaminated clams to survive in the presence of toxins....

Rabies spread speeds up

... new study reported in the freely-available online journal PLoS Biology, Real and colleagues apply a mathematical model to predict the likely spread of rabies across Ohio - a potential gateway for spread throughout the Midwest - and find that raccoon rabies could spread throughout the state in just three yea...

Scientists identify genes responsible for 'black rot' disease in vegetables

...pathogen to date, is published online today in the journal Genome Research. "Black rot" is caused by the pathogenic bacterium Xanthomonas campestris pathovar campestris (or Xcc). Under favorable conditions (high humidity and temperature), Xcc infects vegetable crops by spreading through the plants' vascular...

Venom doc tracks down snake bioweapons

...His results are reported in the March issue of the journal Genome Research. Venomous snakes, all of which belong to the superfamily Colubroidea, evolved glands for the storage and dispersal of their saliva approximately 60-80 million years ago. Since that time, various prey-immobilizing toxins have evolved ...

Engineers improve plastic's potential for use in implants by linking it to biological material

... Technology. It was published online May 15 by the journal Nature Materials. Polypyrrole is of interest for tissue engineering and other purposes because it is a non-toxic plastic that conducts electricity. As a result, it could be used to extend previous experiments in Schmidt's laboratory. The experiments...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

...o 50 per year. These findings were reported in the journal Science in 2001. Not only do insects interact with people, some insect species share characteristics with humans, Waldbauer said. For example, the tsetse fly has an analogue of a mammalian uterus. "Milk-secreting glands that empty into the 'uterus' ...

Atmosphere may cleanse itself better than previously thought

... this week's (May 9?3) online early edition of the journal Proceedings of the National Academy of Sciences. It will appear in the print edition on May 24 (vol. 102, issue 21). Much air pollution consists of chemicals called hydrocarbons, which are produced when we burn organic matter such as wood or fossil ...

Active Vaccine Prevents Mice From Developing Prion Disease

...he new findings, published online this week in the journal Neuroscience, could provide a platform for the development of a vaccine to prevent a group of fatal brain diseases caused by unusual infectious particles called prions. Although no cure for these diseases -- which include scrapie, mad cow disease, a...

NYU, Rockefeller researchers find complexity of regulation by microRNA genes

.... The paper, published in the latest issue of the journal Nature Genetics, found that a microRNA gene regulates, on average, 200 different human gene transcripts and that many microRNAs can coordinate their activities to regulate specific target genes. The paper contains detailed genome-wide predictions for...

Researchers Identify Cause of Early Bird Sleep Disorder

...report appears in the March 31, 2005, issue of the journal Nature. The sleep-shifting mutation they found is in "a gene that was not previously shown in mammals to be a circadian rhythm gene," Ptacek explained. It's not yet clear how the mutant gene works to shift people's sleep time, their circadian rhythm...
