Mad Cow Resistant Cows Scientists
say they have produced the first cattle that may be biologically
incapable of getting mad cow disease. These bulls in South Dakota were
genetically engineered to be free of prions which makes them resistant
to mad cow disease.
Insect Repellants to target CO2 Receptors Rockefeller
University researchers have identified two proteins expressed by
CO2-sensing neurons in drosophila fruit flies and mosquitoes--a
discovery they say could help them design better insect repellants to
shield us from the disease-laden bugs.
Scientists find junk DNA's function For
long, the scientific community believed that 97 per cent of DNA
material is junk. However, an Indian study clearly demonstrated that
the Y-chromosomal junk DNA interacts and controls the function of a
gene located in another chromosome.
Cell Transplants make Blind Mice see again Scientists
have restored the vision of blind mice by introducing light-sensitive
cells into the rodents' retinas. The study invigorates the search for
cell transplants that might someday restore the vision of millions of
DNA Unbeatable at playing Tic-Tac-Toe A
computer that uses strands of DNA to perform calculations has mastered
the game tic-tac-toe. After a human has added an input DNA sequence,
the MAYA-II uses a system of DNA logic gates that results in a chemical
reaction marking the next move.
Beat malaria, eat Limburger! B.
Knols and R. de Jong of Wageningen University in Holland won the
IgNobel prize, the humorous alternative to the Nobel prizes. They
showed that malaria mosquitoes are attracted equally to the smell of
limburger cheese and to the smell of human feet
Scientists Publish First Tree Genome Scientist
have published the first complete DNA sequence of a tree, the black
cottonwood or Populus trichocarpa. The research was funded by the U.S.
Department of Energy. The research may lead to more cost-effective
Fruit juices may reduce Alzheimers risk In
a epidemiological study, researchers from Vanderbilt medical center
found that people who drank 3 or more servings of fruit and veg juices
per week had a 76 pct lower risk of developing Alzheimers than those
who drank juice less than once a week.
Spraying Viruses on Meat making it More Safe Last
week the FDA approved a cocktail of six living viruses to be sprayed on
cold meat before it is packaged. The viruses are bacteriaphages, which
means they only attack bacterial cells and protect the meat against
Fastest Evolving Human Gene Boosts Brain The
fastest evolving gene in the human genome is linked to brain
development. Scientists at the University of California have identified
the rapidly evolving region of DNA which is found out to be important
in the development of the cerebral cortex.
