22nd amino acid synthesized and added to genetic code of e. coli bacteria

...ino acids uses a specialized translator protein to decode genetic information as that amino acid. But selenocysteine lacked its own translator protein and is put into the protein through a more circuitous route. That left open the question of whether future amino acids would follow the traditional path of t...

Convulsions in worms mimic epileptic seizures

...opes that the C. elegans convulsion model may help decode the mysteries of epilepsy and perhaps lead to better treatments for seizures. Researchers can knock out genes rapidly in worms, treat them with a variety of chemicals, and use other genetic techniques that are not possible with human patients. "Epil...

Brain signal predicts working memory prowess

...e visual representations and allows us to coarsely decode them, revealing how many objects are being held and their location in the visual field," explained Vogel. To find out if the amplitude of detectable signals reflects the number of object representions held in visual memory, the researchers presented...

Brain areas identified that 'decode' emotions of others

...nt first step [in theory of mind] is being able to decode other people's mental states, and that this skill is carried out within a very specific neural pathway,"says Dr. Sabbagh. The researchers used a technique called event-related potential.This involves fitting people with what looks like a hairnet cont...

Scientists discover way to streamline analysis of maize genome

... in the United States, so developing strategies to decode its complex genome is a high priority. More importantly, the techniques that we have developed will be useful in the analysis of many other crops such as soybean whose genomes are also highly repetitive." The two filtration techniques met...

New way to lock DNA-slicing enzyme onto chromosomes could lead to novel anti-cancer drugs

...ay that an enzyme crucial to the cell's ability to decode genes and duplicate chromosomes can be turned into...ay for other enzymes to unravel the DNA and either decode a specific gene or duplicate the entire chromosome. Normally, Top 1 moves along the DNA, clipping t...

Researchers describe new technique for cataloging RNA targets in rare brain disease

...ght of as merely the chemical messenger that helps decode DNA's genetic instructions for making proteins, can itself play a crucial role in regulating protein expression. Not surprisingly, this regulation occurs through proteins that bind to RNA. All cells in the body, especially nerve cells in the brain, u...

Turkey genome research may help producers breed a better turkey

...estic turkey (Meleagris gallopavo). In order to decode the genome, researchers first had to collect and separate the DNA. They then applied chemical processes to the samples to enable them to identify the sequences, or ordering, of the building blocks of the DNA. These building blocks are the four diff...

UCR entomologists report bee-dancing brings more food to honeybee colonies

...t have convinced most scientists that the bees can decode the direction and distance information, but the relative role of odor and location information has remained in question. To test the effect of the information in the dance, Sherman and Visscher turned the normally vertical beehive on its side. With t...

JGI to decode DNA of destructive plant pathogen

... Bioinformatics Institute (VBI) in Blacksburg will decode and study the genomes of two species of Phytophthora, which is Greek for "plant devourer." Phytophthora is a fungus-like microbe responsible for sudden oak death syndrome, soybean root rot, and a wide variety of other destructive plant diseases, incl...

Special report: Personal genomics

...t-entrepreneur who raced government-funded labs to decode the human genome. Earlier this year, he was ousted from Celera, the genome company he founded. But he has bounced back with a plan for a massive non-profit genome sequencing centre in Maryland. And in a widely publicised bid to attract funding for th...

Scientists decipher genetic code of malaria parasite

...nce it started in 1996. The genome was so tough to decode because about 80% of its sequence consists of only two of the four DNA chemical building blocks. "That makes the parasite's DNA very difficult to isolate and to sequence," Gardner said. "We persevered because we knew that this project would lay the ...

Joint Genome Institute to sequence key African frog genome

...ure is similar to humans but smaller and easier to decode than that of other frog species. "Frogs and other amphibians occupy a key evolutionary position between mammals and fish, the organisms whose genomes have been or are currently being sequenced," said Paul Richardson, the JGI project manager. "The pu...

New amino acid discovered; Fundamental building block of life

... "We realized that we had to know which tRNA would decode that amber codon," Krzycki said. "Finding it was an essential part of the puzzle." He believes this will be a very rare amino acid, given the fact that it has taken so l...

AAAS announces Science Journalism Award winners

...f Life" (17 April 2001). They followed the race to decode the human genome between the Human Genome Project and Celera Genomics. The producers won the award for portraying the impact of science on society and keeping a well-exposed topic stimulating through an exciting mix of interviews, sharp writing, and ...

Introducing the biology of the future

... to create a menu. The next task for biology is to decode the proteome, understanding the functions of molecules and charting their interactions, and Anne-Claude Gavin, Giulio Superti-Furga and their colleagues have now made a major step towards this goal. Although researchers have known that proteins frequ...

U-M scientists reveal prostate cancer's molecular fingerprint. Study links proteins to patient prognosis.
