US/African project deciphers deadly parasite genome

...that Theileria lacks are found in an intracellular structure called the apicoplast. "This information could be used to develop drugs that could be targeted specifically at each parasite or at several related parasites," he says. TIGR determined the genome sequence of T. parva and shared in the annotation of t...

Scientists unpick genetics of first 15 minutes of life

...mazingly we still know relatively little about the structure of sperm DNA and the genetic processes involved in the most crucial early phases of reproduction." Because of the particular type of histone protein used in the re-packaging of sperm DNA, the researchers believe that this process leaves its mark in ...

Study hints at role of stem cell genes in testicular, breast cancers

...s, and go through a multi-stage evolution in their structure and genetic activity before attaining their mature state. The study revealed that the genetic misregulation leading to seminomas begins very early in the formation of sperm-producing germ cells. Next, turning to cancerous tissue outside of the repro...

Applying ecological laws to bacteria

...is discovery implies that similar processes, which structure the communities of large organisms, also determine those of microbial communities. Engineering machine metal-cutting fluid reservoirs are used as coolants and lubricants in metal machining processes. The reservoirs of the machines studied, such as l...

Amphetamines reverse Parkinson's disease symptoms in mice

...inson's," Gainetdinov said. "However, the chemical structure of amphetamines may lead to new, amphetamine-like drugs, that might provide a more lasting and beneficial alternative to L-DOPA in the treatment of Parkinson's disease." ...

Study provides insight into cellular defenses against genetic mutation

...hat is critically significant because, knowing the structure and role of CBP80, we can now seek to develop drug-based gene therapies that interfere with it in cases where NMD contributes to disease-causing protein shortages." Researchers may be able to convert mRNA quality control from NMD over to a more flexi...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

..., there is another enzyme, tautomerase, that has a structure similar to that of CaaD and catalyzes a reaction that's involved in conventional metabolism," he said. "So it's thought that tautomerase and CaaD may have a common evolutionary origin. The surprise is that the 'new ' enzyme is better at catalyzing th...

Chernobyl: The true scale of the accident

...e ostracism felt by the newcomers. The demographic structure of the affected areas became skewed since many skilled, educated and entrepreneurial workers, often younger, left the areas leaving behind an older population with few of the skills needed for economic recovery. The older population has meant that d...

Anti-cancer Compound In Beer Gaining Interest

...n hops. Researchers started studying its molecular structure in the 1950s, but for decades the only people who showed any real interest in it were brewers, who were trying to learn more about how hops help impart flavor to beer. In the 1990s, researchers at OSU, including Stevens and toxicologist Don Buhler, ...

Researchers find gland that tells fruit flies when to stop growing

...e of the prothoracic gland, part of a more complex structure called the ring gland, and send false signals about a fly's weight. Enlarging the gland by increasing insulin signaling triggered metamorphosis at smaller sizes than usual. Suppressing the gland's growth by decreasing insulin signaling allowed larvae...

Cornell finds natural selection in humans

These mutations are subject to weak negative selection, according to the study. In general, negative selection eliminates from the population very harmful changes to p...

New antifreeze protein found in fleas may allow longer storage of transplant organs

...oths, AFPs in snow fleas break down and lose their structure at higher temperatures," explains Dr Davies, Canada Research Chair in Protein Engineering. "This means that if used to store organs for transplants, they will be cleared from a person's system very quickly, reducing the possibility of harmful antibod...

New molecule may aid in production of biofuels and fungi-resistant plants

...ghly specific interactions that disrupt the chitin structure making the individual sugar chains in the chitin polymer more amenable to enzymatic degradation. The discovery of this new protein that participates in chitin degradation has many potential applications. For example, transgenic plants that expresses...
