Affymetrix 500K array used to identify memory gene

... genetic blueprints of people with good memory vs. poor memory and looking for the genetic variations consistently present in one group, but not the other. They then validated their discovery by replicating the Kibra gene finding in two separate and distinct groups of subjects. "This memory study is a ...

Where HIV rates are high, this allows particularly rapid spread of the disease within hospital settings and the community. Dr Lawn says several responses to this problem are requ...

Researchers create genetically matched embryonic stem cells for transplantation

...of imprinted genes has been linked with cancer and poor growth in some tissues. In addition, embryonic stem cells created through parthenogenesis may have some regions of their genome that contain duplicated copies of mutant genes that have been linked with malignancies or abnormal tissue growth. "Right...

Brain regions do not communicate efficiently in adults with autism

...ated neural activity," said Murias, "which implies poor internal communication between the parts of the brain." The UW researchers analyzed EEGs from 36 adults, ranging in age from 19 to 38. Half the adults had autism and all had IQs of at least 80. The EEGs, which measure the activity of hundreds ...

Research holds promise for herpes vaccine

...rom a theoretical standpoint, subunit vaccines are poor mimics of a natural virus infection," Halford said. "There's not enough there for our immune systems to build a protective response against the actual virus." Halford, 38, is aware that his approach is controversial. "This is where I'm young en...

Two particular bacteria , enteropathogenic E.coli (EPEC), which causes a persistent infection lasting more than 14 days, and Shigella, the cause of dysentery - are the most deadly in terms of killing children. They cause only 20% of cas...

New research to cut animal testing
