Alzheimer's disease to quadruple worldwide by 2050

...mer’s disease. However, if we can make even modest advances in preventing Alzheimer’s disease or delay its progression, we could have a huge global public health impact.” According to Brookmeyer and his co-authors, interventions that could delay the onset of Alzheimer’s disease by as little as one year wou...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...t cancer would benefit from more information about advances in treatments after surgery.” According to the survey, nearly all respondents were aware of chemotherapy and radiation. However, fewer than one out of four had heard of newer therapies such as aromatase inhibitors or monoclonal antibodies, nor we...

Researchers demonstrate way to control tree height

...e ornamental tree industry and agriculture. The advances for cereals have been part of the “Green Revolution,” in which plants such as rice or wheat were created that directed less energy to height growth and more to development of stout stems and plentiful seed. In orchards, semi-dwarf fruit trees produce...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...g insects that have subsequently allowed important advances in understanding how the human immune system works." As part of their innate immune system, insects use an enzyme called phenoloxidase to produce reactive molecules that kill bacteria and then encapsulate them in a dense coat of black pigment call...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

... MD, and colleagues. "This is an example of how advances in genetics research feed into practical applications. This research would not have been possible a very few years ago. We now have a new molecular target scientists can investigate in their search for better medications for bipolar disorder," said...

World's leading scientists announce creation of 'Encyclopedia of Life'

...ears ago, we could not create such a resource, but advances in technology for searching, annotating, and visualizing information now permit us, indeed mandate us to build the Encyclopedia of Life." Over the next 10 years, the Encyclopedia of Life will create Internet pages for all 1.8 million species curre...

Researchers attach genes to minichromosomes in maize

...any new avenues. If we can do this in plants, many advances could be done in agriculture that would not otherwise be possible, from improved crops to inexpensive pharmaceutical production to other applications in biotechnology,?said Birchler, professor of biological sciences in the MU College of Arts and Scie...

MIT's ocean model captures diversity of underwater forests

...t the genetic diversity of marine microbes, recent advances in computational capability and a simple recognition of his own bias. "Physicists, like myself, have a bit of a reductionist view. We often shy away from the complexity of the real world in our models and prefer to reduce things to the simplest ca...

Scientists identify pancreatic cancer stem cells

...is possible to do so, she added. The study also advances the emerging notion that stem cells may lie at the heart of some, if not all, cancers, Simeone said. That theory suggests that only cells that have the properties of "stemness" -- that is, cells that can self-renew and differentiate into other types ...

Tundra disappearing at rapid rate

...tional thinking on treeline dynamics has been that advances are very slow because conditions are so harsh at these high latitudes and altitudes," said Dr. Ryan Danby, from the Department of Biological Sciences. "But what our data indicates is that there was an upslope surge of trees in response to warmer temp...

Sandia researchers take new approach to studying how cells respond to pathogens

...at a time." The research is possible because of advances in several Sandia-developed tools, including: Microfluidics that allows researchers to do single-cell experiments Advanced imaging that allows researchers to image individual cells with much higher information content than possible w...

UCI scientists reconstruct migration of avian flu virus

...tive importance of the geographic and evolutionary advances the virus makes. From 192 samples obtained across Eurasia, the UCI team reconstructed the virus's geographic reach and evolution. The analysis shows that Guangdong ?home to a large poultry industry ?is the source of many H5N1 strains that have spr...

Study examines risk of soft tissue sarcomas in hereditary retinoblastoma survivors

"Improved treatment can be expected to reduce the incidence of ...

Protein overexpression at heart of heart failure

...tions.1 Molecular mechanisms are being studied and advances have been made in a minority of cases, e.g.: the familial forms. Intracellular [Ca2+]i homeostasis is essential for normal cardiac function and integrity, and dysregulation of [Ca2+]i is a hallmark of advanced heart failure.2 The primary trigger for ...

Elucidation of the genome for diabetics with DNA chips
