Chemists create 'Superbowl' molecule; May lead to better health

...tion, he adds. There are hurdles to overcome. The current version of the superbowl molecule lacks solubility in water, which could compromise its potential medical applications, the researcher says. Superbowl molecules also have the potential to be toxic. But Sherburn and his associates are confident these ...

Molecular biology fills gaps in knowledge of bat evolution

...ng-standing problems in evolutionary biology. The current findings lay the groundwork for further research that, Springer hopes, will expand the coverage of classifications of bats from the family level to the genus level and probe in more detail into the bat evolutionary record. He also plans to compare th...

University of Manchester makes made-to-measure skin and bones a reality using inkjet printers

...ng to thesurface' which is a major disadvantage of current methods that infusethe cells into the structure after it has been built."The problem is getting cells into the interior of these constructionsas they naturally stick to the sides of whatever they are beinginserted into. If they stick to the sides the...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice

...imprinting of IGF2 and colon cancer in people, the current experiments were designed to find out whether the loss of imprinting is involved in cancer's development or just in its progression. "Most researchers, including me, expect epigenetic differences to influence progression -- whether a tumor would gro...

"We'vebeen using triclocarban for almost half a century at rates approaching1 million pounds per year, but we have essentially no idea...

Researchers Uncover Key Step In Manufacture of Memory Protein

...mechanism she and her colleagues deciphered in the current study may provide insight into long-term memory deficits. She explained that other researchers have learned that some human beings lack normal CPE due to mutations in the CPE gene. Future research may determine if the CPE mutation affects these indiv...

Scientists Replicate Hepatitis C Virus in Laboratory

...nfections worldwide and the type most resistant to current therapies. They constructed an HCV replica using a DNA copy of the original HCV single-strand RNA genome. They placed the DNA copy between two ribozymes, RNA molecules that have enzymatic function and can cleave RNA sequence at specific locations. Th...

The secret to longevity in tubeworms

... body that it tunnels into the sediments. However, current measurements of sulfide and sulfate fluxes in the water near the vents do not match the observed tubeworm colony size and individual longevity, leading Cordes et al. to propose that L. luymesi also uses its roots to release sulfate back to the microb...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

...ample. In short, it does this by using an electric current to propel ionized proteins toward a detector. The number of ions hitting the detector at each mass-to-charge ratio (also known as m/z ratio) is recorded to produce a protein spectrum. A peak in the graph of the spectrum represents a protein (the iden...

The current publication provided a completed fine map for the paternal strain¡°93-11¡± (Indica), and its comparison with the genome sequence of the Japonica. It is reported that BGI will finish whole genome assembly and analysis for the maternal strain "PeiAi 6...

These approaches are not yet being tested in humans, but Krebsbach said some small clinical trials are under consideration. If the combination therapy approach works, Krebsbach said the next step would be working with engineers to ...

This information is critical to current discussions of the International Whaling Commission (IWC) because some argue that the recent surge in minke populations is unprecedented and is hampering the recovery of other whales, pointing to the need for resumed whaling. Yet the whales?varied DN...

Goldstein said the results are important for a few reasons. Because skate red blood cells closely resemble cells ...

Color-blind method opens new doors in DNA sequencing
