Tanks were an important weapons system in World War II. Even though tanks in the inter-war years were the subject of widespread research, production was limited to relatively small numbers in a few countries.
lacked the genes and enzymes required to manufacture a long list of neurotransmitters widely seen in other animals. These missing neurotransmitters included not just the ones that Moroz had noted back in 1995 – serotonin, dopamine and nitric oxide – but also acetylcholine, octopamine, noradrenaline and others. The ctenophore also lacked genes for the receptors that allow a neuron to capture these neurotransmitters and respond to them.
A new device can begin repairing damaged organs in seconds, heralding a major breakthrough for life-saving medicine. Developed at Ohio State University, the technology known as tissue nanotransfection (TNT) uses a small coin-sized silicon chip that "injects" genetic code into skin cells, converting them from one type to another.
Silicon Valley is a nickname for the southern portion of the San Francisco Bay Area, in the northern part of the U.S. state of California. The "valley" in its name refers to the Santa Clara Valley in Santa Clara County, which includes the city of San Jose and surrounding cities and towns, where the region has been traditionally centered. The region has expanded to include the southern half of the San Francisco Peninsula in San Mateo County, and southern portions of the East Bay in Alameda County.
