Don’t get ready for Scotty to beam you up quite yet, this is the teleportation of information. Though researchers have come close in the past, previous attempts transported incomplete or inconclusive information. It’s important to note that the information isn’t really traveling, rather, it effectively exists in two places at the same time.
The experiment's success was credited to a hybridized technique that blended the technology used for teleporting light along with reducing the frequency range of qubits. The ability to teleport information means that quantum computing may be getting closer to becoming reality.

While trying to create graphene, scientists accidentally developed the glass which is only two atoms thick. Researchers were actually able to see individual silicon and oxygen atoms under an electron microscope. This has helped answer questions about the structure of glass, which has stumped scientists for over 80 years.
The folks at the Guinness Book of World Records took note of this ultra-thin glass, and the scientists involved will be featured in the 2014 book.

Demodex folliculorum and Demodex brevisare are parasitic mites that particularly favour the hair follicles of eyebrows and eyelashes and measure a mere fraction of a millimeter long. They crawl about your face in the dark to mate and then crawl into the pores to lay their eggs and die. Healthy adults have around one or two mites per square centimetre of facial skin, though people with the condition rosacea can have 10 times more. Demodex does not have an anus and therefore cannot get rid of its faeces. Instead, their abdomen gets bigger and bigger, and when the mite dies it decomposes and releases its faeces all at once into the pore.

This creature lived 419 million years ago, and the discovery of its fossils may disprove the theory that all modern animals with a bony skeleton evolved from shark-like creatures with cartilage skeletons.

While scientists have been able to generate biodiesel from bacteria, biogasoline has been much more elusive. A team in Korea have successfully engineered E. coli bacteria that produce the short-chain alkanes of gasoline.
