View smaller image It may walk like a Japanese robot, but it's thinking like a monkey in the United States. Japanese and US researchers said Wednesday they have created a humanoid robot that acts according to the brain activity of a monkey all the way across the Pacific. The experiment was part of efforts to develop prosthetic limbs which can be mentally controlled by people with disabilities. A laboratory in the western Japanese city of Kyoto unveiled a 155-centimetre (62-inch) tall humanoid, with a friendly-looking face including bulging black eyes, who walked via signals coming into its legs through wires. Duke University in North Carolina. "We were able to detect the monkey's brain activity while walking on the treadmill and relay the data via net from the United States to Japan," the state-backed Japan Science and Technology Agency said in a statement.

Experiments to create Britain’s first embryos that merge human and animal material will begin within months after a Government watchdog today approved two research teams to carry out the controversial work.
Scientists at King’s College London and the University of Newcastle-upon-Tyne will now inject human DNA into empty eggs from cows, to create embryos known as cytoplasmic hybrids that are 99.9 per cent human in genetic terms.
cloning embryo
The cloning controversy is back in the headlines. A California company says it's produced the first human clone embryo. Stemogen is the name of the company.
Its doctors took an egg from a female donor and replaced the egg's DNA with DNA taken from an adult skin cell. The cells were then grown in a Petri dish.
The company claims that three of the five cell clusters were proven to be clones. The cloned embryos were destroyed after they were tested, but doctors say they would have grown into fetuses if implanted in a surrogate womb.
This process was documented in the on-line journal Stem Cells.

gene combo prostate cancer
Scientists have taken a key step toward revealing the causes of prostate cancer, finding that a combination of five gene variants dramatically raises the risk of the disease. Added to family history, they accounted for nearly half of all cases in a study of Swedish men.
