Getting to know your roots

The Genographic Project aims to map historical human migration patterns through collecting and analyzing DNA samples from many people all over the world. The project has already been around for almost two years, and perhaps its main attraction resides in that everybody can find out about their own personal lineage, if they purchase the [...]

Iron Fertilization Of Oceans against global warming

Global warming is a hot topic everywhere in the world. And probably we humans should be blamed for that. The careless use of resource and greed and lack of respect for mother earth could be what leads to our demise. The signs are everywhere but at first they were more obvious in the oceans. So [...]

New Light Shed On The ‘Hobbit’

Homo floresiensis (”Man of Flores”, nicknamed Hobbit) is the name for what may be a species in the genus Homo, remarkable for its small body, small brain, and survival until relatively recent times. It is a 3-foot-tall, 18,000-year-old hominin skeletondoes and it does not have a chin and it has a low twist in the [...]

Nanotubes seen inside living animals

Carbon nanotubes (CNTs) are allotropes of carbon. Their strength and flexibility makes them useful in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering. They are also used in concrete where they increase the tensile strength, and halt crack propagation in elevators, bridges, circuits, magnets, transistors, and they are [...]

What Is Genetic Engineering

So according to Wikipedia it involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein to reach desired effects. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, enhancing existing ones, [...]
