Radiologists attempt to solve mystery of Tut's demise

...ge of preservation," said Dr. Selim. "The body was cut into several parts with some missing pieces." With the help of the CT images, researchers estimated King Tut's age at death to be between 18 and 20 years. His height was 180 centimeters or approximately 5 feet 11 inches. The researchers discover...

Buildup of damaged DNA in cells drives aging

...hanism by which skin and other cell types normally cut out, or excise, damage to their DNA caused by UV light. Defects in one DNA repair mechanism, nucleotide excision repair (NER), causes xeroderma pigmentosum, a rare disease in which people have a 2,000-fold increased risk of skin cancer from sun expos...

Gene chip technology shows potential for identifying life-threatening blood infection

...sis, which can take several days. Gene chips could cut the typical time needed for diagnosis to eight hours or less, Cobb says. In the new research, Cobb and his colleagues mimicked sickness in four groups of mice: each of three groups had a varying severity of sepsis and a fourth had systemic non-inf...

Holiday gluttony can spell disaster for undiagnosed diabetics

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...els are not only attractive for their potential to cut reliance on oil imports but also their reduced environmental impact," said Dr. Gerald A. Tuskan, ORNL and DOE JGI researcher and lead author of the SCIENCE study. "Biofuels emit fewer pollutants than fossil fuels such as gasoline. In addition, popl...

Male circumcision reduces HIV risk, study stopped early

...counseling," Bailey said. "We can't expect to just cut off a foreskin and have the guy go on his merry way without additional tools to fight against getting infected." Opponents of circumcision have speculated that circumcised men may feel they are not at risk of contracting HIV and may be more likely...

Climate experts search for answers in the oceans

...modification of the water circulation patterns may cut off or modify some of that primary production, so it is important to know both sea-surface temperature and ocean colour." In order to make the most of all satellite information available on ocean colour and sea-surface temperature, ESA is merging...

Electric jolt triggers release of biomolecules, nanoparticles

... surface," he said. "We use an electrical pulse to cut the tether, and it floats away." This method could be used to control the release of drug molecules; nanoparticles; biopolymers such as peptides, proteins and DNA; and protein assemblies such as viruses, said Searson, who also is director of the In...

New system could drastically reduce herbicide use

...d, while the second layer applies herbicide to the cut weed. "This type of application is extremely effective," said Tian, "because it applies herbicide directly to the plant, instead of broadcasting uniform rates across a field." With this level of precision, Tian says the system has clear environ...

End of deforestation in view? Experts advance new way to size up global forest resources

...e huge areas of tropical forests are rapidly being cut and cleared. Encouragingly, in many other tropical areas forests are re-growing. Studies in Central America show tree cover in El Salvador grew by about one-fifth from 1992 to 2001. Forests are also recovering fast in the Dominican Republic, in ha...

Protein splicing upsets the DNA colinearity paradigm

...roteasomes,' components of the cell machinery that cut foreign proteins into peptides that are then displayed on the cell surface for recognition and destruction by CD8+ T lymphocytes. However, the Belgium/USA team has found that proteasomes can also splice the peptide fragments together in a reverse ord...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

...s placed alongside the endoscope allow surgeons to cut away inflamed tissue and polyps, clearing a path for the sinuses to drain normally. Lane says that if left untreated, polyps can lead to severe blockage and recurring infections. All patients were monitored for a minimum of nine months to see if...

Novel pathway regulates timing of brain cell development

...er protein called neuregulin 1 (NRG1), and then is cut in two by a third critical protein called presenilin, the researchers showed. The half of erbB4 that resides inside the cell--a protein called E4ICD--then joins with other proteins in the cell and travels to the cell nucleus. "Once in the nucleus, E4...

Brown scientists map structure of DNA-doctoring protein complex

...), the protein "surgeon" that allows mobile DNA to cut into a chromosome, insert its own genes, and then sew the chromosome back up. That work was conducted using the lambda virus, which infects Escherichia coli (E. coli) bacteria and serves as a model that scientists use to understand mobile DNA. Now...

NHGRI aims to make DNA sequencing faster, more cost effective

...complex diseases. Ultimately, NHGRI's vision is to cut the cost of whole-genome sequencing to $1,000 or less, which will enable the sequencing of an individual's genome during routine medical care. The ability to sequence an individual genome cost-effectively could enable health care professionals to tai...

Record ozone loss during 2006 over South Pole

...spheric mass above the Antarctic continent is kept cut off from exchanges with mid-latitude air by prevailing winds known as the polar vortex. This leads to very low temperatures, and in the cold and continuous darkness of this season, polar stratospheric clouds are formed that contain chlorine. As th...
