Researchers wake up viruses inside tumors to image and then destroy cancers

...st Martin G. Pomper, M.D., Ph.D. "This is the only example we know of where it is possible to image activated endogenous gene expression without having to transfect cells." A variety of blood and solid cancers are more likely to occur in people who have been infected with the Epstein-Barr virus (EBV), but...

Flies don't buzz about aimlessly!

... flying Drosophila appear to be the first reported example of searching behaviour that is both scale-free and intermittent. This suggests that these behaviours are not part of two different searching strategies, but rather represent a single very effective and perhaps widely adopted strategy." Mark Frye beli...

Biodiesel study targets cleaner air, cleaner engines

...t in transportation fuels by 2010. This is another example of how we can create new economic opportunities for farmers and the agricultural sector while also taking care of our environment." Natural Resources Canada contributed $300,000 to the project, with other partners Environment Canada, Agriculture an...

2 brains -- 1 thought

...minimal. "Applied to a real network, one could for example analyse which structural optimisation principles function in evolution," says Timme. The dynamics of a number of very simple networks that generate repetitive patterns - like the insect walking pattern - are already well-understood. Has evolutionary ...

A 'traffic light' for neurons means 'go' for improving brain research

...ector Elias A. Zerhouni. "The work is also a prime example of the highly innovative approaches to major challenges in biomedical research that we support through the NIH Director's Pioneer Award program." Karl Deisseroth, an assistant professor of bioengineering and of psychiatry who led the research grou...

In obesity, brain becomes 'unaware' of fat

... but it’s not doing its job,?Cowley said. “It’s an example of classic hormone resistance.? Cowley’s group set out to show exactly where that breakdown occurs. The researchers fed mice a high-fat diet for 20 weeks, a long time for the mice, which live only for a couple of years. For reasons that remain uncl...

Good behavior, religiousness may be genetic

...is type of behavior." This research is another example of the way that genes have an impact on behavior. "Society as a whole assumes that home environments have large impacts on behavior, but studies in behavior genetics are repeatedly showing that our behavior is also influenced by our genes," says Koen...

Study finds antibiotic resistance in poultry even when antibiotics were not used

...and keeping other foods away from raw chicken, for example ?to minimize the risk of illness. "All foods have the potential to contain pathogens ?all of them," Lee said. "There's no substitute for good food handling and preparation." ...

LIAI completes world's most comprehensive analysis on influenza virus data

...f a particular epitope had been used one time, for example by a single individual responding to a single virus, or 100 different times. Now, scientists can search the database and find out all existing information on their particular topic. This will enable them to avoid unnecessary repetition and make fas...

Prehistoric origins of stomach ulcers uncovered

...controversial questions about human migration. For example we could use our understanding of the bacteria's spread to gauge poorly understood human population shifts in Europe, Africa and Asia." ...

Mimicking how the brain recognizes street scenes

...lligence. "We chose street scene recognition as an example because it has a restricted set of object categories, and it has practical social applications." Near-term applications include surveillance and automobile driver's assistance, and eventually visual search engines, biomedical imaging analysis, rob...

NIAID DNA vaccine for H5N1 avian influenza enters human trial

...ently pose a threat in Indonesia and represents an example of our ability to respond to shifting viruses with modern technology," says Dr. Nabel. The study will enroll 45 volunteers between the ages of 18 and 60. Fifteen will receive placebo injections and 30 will receive three injections of the investiga...

Misclassified for centuries, medicinal leeches found to be 3 distinct species

...ial conservation status. "This study is a great example of why the field of taxonomy [the science of classification of organisms] is so important," said Patrick Herendeen, program director in the National Science Foundation (NSF) Division of Environmental Biology, which funded the research. "Taxonomists h...

A rarity among arachnids, whip spiders have a sociable family life

...been reported in amblypygids. "This was the best example I had ever seen of friendly behavior in an arachnid," said Linda Rayor, senior research associate in entomology and the lead author of both articles. Rayor describes in the articles how mothers habitually stroke their offspring with their long, thin ...

Why aren't humans furry? Stone-Age moms could be the answer

.... Professor Rees said: "This paper is an excellent example of the kind of bold thinking and theorizing which David Horrobin intended to encourage when he began Medical Hypotheses. I hope that Judith Rich Harris' idea provokes debate and further investigation of this topic." ...

Scientists clone mice from adult skin stem cells

...bryonic stem cells from the skin of a patient, for example an Alzheimer's patient, these embryonic stem cells might be used in the laboratory to enable scientists to generate neurons and study the neurodegenerative process. ...

In addition, Springer has committed up to $10,000 annually in grants and prizes for the best paper, the best lesson plan, etc. The journal, aimed at members of the educational, museum, and s...

How badger culling creates conditions for spread of bovine TB

...t the social disruption of badger populations, for example by culling, is likely to promote disease spread." Data for the study came from an undisturbed high-density badger population in the Cotswolds, Gloucestershire, that has been intensively studied by ecologists for more than 15 years. The authors ana...

Putting an old drug to a new use

...blood pressure. "Our discovery is an excellent example of how the combination of basic research and the expertise of clinicians can yield results that are relevant to medicine and could ultimately benefit patients," says Matthias Hentze, Associate Director of EMBL and co-author of the study.
