The power of quantum mechanics for data transmission is intriguing because of potential for secure, high speed communications but current storage and transmission of quantum information is far too fragile to have any practical value in the near term.

In classical communications, a bit can represent one of two states - either 0 or 1. But because photons are quantum mechanical objects, they can exist in multiple states at the same time. Photons can also be combined, in a process known as entanglement, to store a bit of quantum information (i.e. a qubit). 
Galileo merged the fields of cosmology and astronomy, thanks to his telescope, which gave scientists a more accurate way to observe and define the heavens. His telescope helped shift authority in the observation of nature from men to instruments. From backyard astronomers to the Hubble Telescope to the Vatican Observatory, Galileo’s impact on astronomy is both formative and lasting.
Galileo's contributions to science in general, and optics and astronomy in particular, were so monumental that over 350 years later we still discuss them in introductory physics courses.
Galileo Galilei wasn't just an Italian physicist, mathematician, astronomer, philosopher and heresy suspect (not to mention father of modern observational astronomy, modern physics, science, and modern science, that last one he was named by both Hawking and Einstein). He was also a friend of the Medici, the political Italian dynasty whose patronage of scientists and artists led to the Renaissance.1
A real life Alice In Wonderland story is a little closer to reality now that researchers in China have created the first tunable electromagnetic gateway.

In a new paper,  researchers from the Hong Kong University of Science and Technology and Fudan University in Shanghai have described the concept of a "a gateway that can block electromagnetic waves but that allows the passage of other entities" like a "'hidden portal' as mentioned in fictions."

The gateway uses transformation optics and an amplified scattering effect from an arrangement of ferrite materials called single-crystal yttrium-iron-garnet that force light and other forms of electromagnetic radiation in complicated directions to create a hidden portal. 
Superman's X-ray vision may be closer than you think.   The tubes that power X-ray machines are shrinking and also improving in clarity.

A team of nanomaterial scientists, medical physicists, and cancer biologists at the University of North Carolina has developed new lower-cost X-ray tubes packed with sharp-tipped carbon nanotubes for cancer research and treatment.   This tiny technology was presented at this year's meeting of the American Association of Physicists in Medicine in Anaheim, California.

The science goal is to image human breast tissue, laboratory animals, and cancer patients under radiotherapy treatment, and to irradiate cells with more control than previously possible with conventional X-ray tubes.   The fun goal will be just about anything else.
Albert Einstein's theory of general relativity, which describes how the gravity of a massive object like a star can curve space and time, has been successfully used to predict the bending of starlight by the sun, small shifts in the orbit of the planet Mercury and the phenomenon known as gravitational lensing.
There's a bipolar force with a repulsive side that doesn't involve cosmic opera or wooden acting - it's light.  And it can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity, according to Yale researchers. 

The team previously discovered an 'attractive' force of light and showed how it could be manipulated tiny switches in semiconducting micro- and nano-electrical systems. They say they have now uncovered its non-evil twin - a repulsive force.
A team of physicists and engineers have demonstrated all-fibre quantum logic, where single photons are generated and used to perform the contolled-NOT quantum logic gate in optical fibers with high fidelity.

The only quantum technology in practical use today is quantum cryptography and is currently limited in the distance over which secure communication may occur.

More sophisticated quantum networks will require multiple nodes with the ability to implement small-scale quantum processing in order to increase the range of quantum communications. Such networks will rely on optical fibre links, making fibre-based photon generation and information processing of key technological importance.
Ounce for ounce, spinach has more nutritional value than iceberg lettuce; in general, darker colors in leafy vegetables mean more antioxidants and therefore more health benefits.

Knowing that, plant physiologists has developed a way to make lettuce darker and redder — and therefore healthier — using ultraviolet light-emitting diodes (LEDs).
