Genetics Could Explain Parrots Ability To Parrot
2012-07-05 04:42:15

redOrbit Staff & Wire Reports - Your Universe Online Scientists say they have put together a more complete string of genetic letters that may control how well parrots learn to imitate their owners and other noises. Researchers unraveled the certain regions of the parrots' genome using a new technology, single molecule sequencing, and fixing its flaws with data from older DNA-decoding devices. Researchers also decoded hard-to-sequence genetic material from corn and bacteria as proof...

Scientists are reporting an advance toward treating disease with minute capsules containing not drugs – but the DNA and other biological machinery for making the drug. In an article in ACS' journal Nano Letters, they describe engineering micro- and nano-sized capsules that contain the genetically coded instructions, plus the read-out gear and assembly line for protein synthesis that can be switched on with an external signal. Daniel Anderson and colleagues explain that development of...

Could First Century Bones Have Belonged To John The Baptist?
2012-06-16 05:35:03

Researchers from Oxford University claim that they have discovered new evidence supporting the notion that a knuckle bone and other human remains discovered under a Bulgarian church could belong to the Biblical figure John the Baptist. According to AFP reports published Friday, the remains, which were discovered two years ago in a small marble sarcophagus buried beneath a church floor on the island of Sveti Ivan, were dated by a university research team. They found that the knuckle bone...

Rice, UCSD scientists study genomes to reveal contacts, refine methods for protein-folding prediction José Onuchic has become an expert at connecting the dots, but finding connections merely implied by the dots “¦ well, that´s quite a trick. The Rice University biophysicist and his team have created a tool to do just that for proteins and, in the process, have advanced the art of predicting their form and function. In this case, the dots are amino acid...

New Weizmann Institute technology speeds up DNA “rewriting” and measures the effects of the changes in living cells Our ability to “read” DNA has made tremendous progress in the past few decades, but the ability to understand and alter the genetic code, that is, to “rewrite” the DNA-encoded instructions, has lagged behind. A new Weizmann Institute study advances our understanding of the genetic code: It proposes a way of effectively introducing numerous...

Scientists Create Rewritable DNA
2012-05-22 13:29:59

Scientists have found a way to create rewritable digital data storage in DNA through means similar to binary coding. The researchers worked to reapply natural enzymes adapted from bacteria to flip specific genetic sequences of DNA back and forth at will. The scientists, who all work in the Department of Bioengineering at Stanford University Medical Center, said their method essentially works like that of binary computer coding. "Essentially, if the DNA section points in one...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...
