Chinese physicists developed the theoretical basis of a new technology that would allow to transform objects from one into another. The appearance of an optical illusion is based on the use of metamaterials, the properties of which depend on the structure, but not on the chemical composition. The materials bend light rays. For example, the metamaterials with the negative refraction in optical frequencies can make an object behind the materials or near them invisible.

Researchers at the University of Sussex in Britain have discovered that cats employ a “soliciting purr” to seduce their owners into giving them more attention and food. The study, published in the July 15 edition of Current Biology journal, says the purr proves irresistible because a high-frequency element embedded within it, similar to a cry or meow, subtly triggers a sense of urgency.
The team of Sussex psychologists discovered that cats appear to be exploiting innate tendencies that humans have for nurturing their own offspring. However, in this case the felines subtly bury their “feed me” messages in an otherwise pleasant purr. Lead author Dr Karen McComb initiated the study because her own cat, Pepo, had the knack of consistently waking her up in the mornings with insistent purring.

History books tell us that the planet Neptune was found in the mid-1800s after years of speculation and search.
But in 1613, more than two centuries before Neptune was officially discovered, Galileo Galilei knew he had found it, according to a new theory by University of Melbourne physicist David Jamieson.
Jamieson has been studying Galileo’s notebooks and found some interesting, buried notations that suggest the great astronomer – then working with a crude, early telescope he crafted himself – was onto something big.
It has long been known that Galileo observed Neptune, but it was thought that he discounted the object as a star and gave it no further thought. But it turns out Galileo may have known the “star” had moved in relation to other stars, Jamieson reveals. That sort of movement would have caught Galileo’s attention, since he knew that it was just the sort of thing planets did.

The world’s largest and most advanced underwater observatory project was launched in a ceremony at Canadian Forces Base Esquimalt in the western Pacific province British Columbia.
The 100-million-dollar Neptune Canada project will make it possible for life beneath the ocean to go live on the Internet, giving people an unprecedented experience. Led by the University of Victoria (UVic), it will provide 25 years of long-term monitoring of ocean events as they occur.
“At a time when our understanding of the oceans is clearly becoming more essential than ever, Neptune Canada will play a leadership role in advancing our knowledge of the oceans in ways not previously possible,” UVic president, said in a statement.
