Scientists are reporting an advance in overcoming a major barrier to the use of the genetic material RNA in nanotechnology "” the field that involves building machines thousands of times smaller than the width of a human hair and now is dominated by its cousin, DNA. Their findings, which could speed the use of RNA nanotechnology for treating disease, appear in the monthly journal ACS Nano. Peixuan Guo and colleagues point out that DNA, the double-stranded genetic blueprint of life, and...

Crystal structure shows how RNA, one of biology's oldest catalysts, is made In today's world of sophisticated organisms proteins are the stars. They are the indispensible catalytic workhorses, carrying out the processes essential to life. But long, long ago ribonucleic acid (RNA) reigned supreme. Now Northwestern University researchers have produced an atomic picture that shows how two of these very old molecules interact with each other. It is a rare glimpse of the transition from an...

A research team led by Teh-hui Kao, professor of biochemistry and molecular biology at Penn State University, in collaboration with a team lead by Professor Seiji Takayama at the Nara Institute of Science and Technology in Japan, has discovered a large suite of genes in the petunia plant that acts to prevent it from breeding with itself or with its close relatives, and to promote breeding with unrelated individuals. In much the same way that human inbreeding sometimes results in genetic...

CARLSBAD, Calif., Jan. 6 /PRNewswire/ -- GenVault Corporation, the leader in ambient temperature biosample stabilization, announces the launch of GenTegra(TM) RNA. GenTegra(TM) RNA is an inert chemical matrix that inactivates trace RNase in the liquid phase, providing an added level of RNA stability during sample handling, with or without ice. In the dry-state, GenTegra(TM) preserves RNA integrity by protecting samples from hydrolysis and oxidation, imparts thermal stability at...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
