The scientists say the work makes it crucial for migraine sufferers to do everything they can to prevent their headaches. Wh...

How to look at dinosaur tracks

...] demonstrate that great care should be taken when describing fossil footprints that have been exposed to subaerial erosion, because the shape, dimensions, and general appearance of the footprint become seriously altered by erosion.? Geologists also must account for whether the step was taken on a sloped surf...

Thymus transplants gives hope to babies with fatal immune disease

...lothes and she loves to dance." Lolita Harding is describing her daughter Dave'yana, who will turn three in September, thanks in large part to a thymus transplant she received at Duke University Medical Center in April 2005 to reconstitute her absent immune system. Dave'yana was the 31st baby to receive such a...

Executable biology -- Computer science sheds light on animal development

The high-resolution maps will enable researchers to use "virtual microscopy" to compare healthy brains with others, looking at structure, gene expression and the distribution of different proteins. They will enable better understanding o...

Uniform language for describing genes of pathogenic and beneficial microbes

Massey researchers induce cell death in leukemia

...he best of our knowledge, this is the first report describing synergistic interactions between HDAC inhibitors and Bortezomib combinations in the setting of CLL," said Grant. "The findings of our study -- as well as the emerging body of preclinical and early clinical data suggesting interactions between HDAC in...

Engineering the heart piece by piece

...irst author Yen-Chih Huang, PhD, published a paper describing their success in growing pulsing, three-dimensional patches of bioengineered heart muscle, or BEHM. That paper describes the use of an innovative technique, using a fibrin hydrogel, that is faster than others, but still yields tissue with significant...

Genomics throws species definition in question for microbes

... (or phenotypic) properties were the only means of describing microorganisms, so the system was based on measurable and observable characteristics of the organisms, not genetic traits. In the late 20th century, molecular biology uncovered the genetic relationships between microorganisms, and some of the sec...

Vaccine to cope with viral diversity in HIV

...the variation found in the strains of the virus by describing the molecules which stimulate the immune response to HIV (immunogens) that have multiple forms of variable elements of the virus. These antigens compress the variation found in many viral strains into lengths suitable for vaccine immunogens. "We can ...

Evolution of Old World fruit flies on three continents mirrors climate change

The research deals with an Old World fruit fly species called Drosophila subobscura, which originally ranged from the Mediterranean Sea to Scandinavia. ...

Vanishing beetle horns have surprise function

...olution report, the scientists examined literature describing the evolutionary relationship of 47 Onthophagus species. They also studied the development of eight beetle species in the laboratory (seven Onthophagus species and one species from the closely related but hornless genus Oniticellus). The scientis...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...ng in the Swaroop lab published an important study describing the "birth" of rod cells.* They were able to make this process visible by building on previous research, using an NRL gene regulatory element to tag the rods with a green fluorescent protein. This enabled Kellogg scientists to illuminate the rods, wh...

New bird discovered on unexplored Columbian mountain

...t the first of several new species that we will be describing from the Yariguíes Mountains. In my own specialist group, butterflies, we have found several new taxa that will be described soon." The new bird discovered was funded due to an on-going commitment to the environment from BP, whom supports the BP C...

The researchers found a significant concordance between activation of certain cortical are...

Bitter taste identifies poisons in foods
