Radiation degrades nuclear waste-containing materials faster than expected
...ds of meters beneath the earth's surface. Doing so necessitates selection of a site with sufficiently stringent geological features to withstand any potential leakage at a cost of billions of dollars. For example, there is an ongoing debate over the safety of the Yucca Mountain site in Nevada. A figure published ...Living view in animals shows how cells decide to make proteins
...anco said. "The complexity of alternative splicing necessitates its visualization as the decisions are occurring, because taking a cell out of its context shows only its current status and not how it arrived at that place." For instance, the splicing process can change even from day to day as an animal develops......eproduction. Progression to blast crisis currently necessitates a bone marrow transplant for survival. "Sometimes the BCR-ABL protein itself has a mutation, which makes it less susceptible to imatinib," said Li. "But in some patients who do not respond to imatinib, there's no imatinib-resistant mutations detect...HYPER-CEST MRI breaks new ground in molecular imaging
...ited by the fast relaxation time of protons, which necessitates the need for large magnetic fields to decrease relaxation effects and increase the difference between saturated and non-saturated MRI signals. It also requires a relatively large amount of the CEST agent to generate significant contrast enhancement. ...Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax
... cause disease and death. This delayed germination necessitates prolonged use of antibiotics after an inhalational exposure. Animal experiments have confirmed the prolonged persistence of spores and incubation period after aerosol exposure. In one study, rhesus macaques were protected during a 30-day course of a...Newly recognized gene mutation may reduce seeds, resurrect plants
... plants likely is a tightly regulated process that necessitates allowing some seed loss to conserve resources in a stressful environment without aborting all seeds, which would leave the plant with no healthy offspring." If researchers learn how to control plant embryo abortion, they may be able to increase yield...Researchers offer proof-of-concept for Altered Nuclear Transfer
...ritics who claim that embryonic stem cell research necessitates the destruction of human life. Scientists and ethicists have debated the merits of this approach, but so far it has not been achieved. "The purpose of our study was to provide a scientific basis for the ethical debate," says Whitehead Member Rudolf J...Novel approach yields predictions validated by experiments
...le and cars are going." Addressing this complexity necessitates the use of advanced mathematical equations based upon biochemical systems theory to describe dynamic biological processes, Void said. These processes include feedback mechanisms that work to stabilize a system much like a thermostat maintains a const...Human complexity and diversity spring from a surprisingly few (relatively speaking) genes
...e forms? The unexpected finding, says Stefan Maas, necessitates a clearer understanding of the role played in protein diversity by processes that take place after DNA is transcribed to RNA and after RNA is translated to proteins. Maas, an assistant professor of biological sciences, studies RNA editing, a phenomen...
