Basically, any liquid column should be able to act as a guide for light, thus behaving similarly to optical fibers. The problem with these liquid fiber optics is that they become unstable after reaching a physical limitation known as the Rayleigh-Plateau instability which states that in free-fall conditions the lengt... |

Mars had liquid water on the surface in its distant past and quite a lot of it too, according to the high-resolution spectrometry images relayed back to Earth by the CRISM instrument on board NASA's Mars Reconnaissance Orbiter. CRISM revealed that there is a great abundance of clay minerals, which usually form i... |

Knowing how solid surfaces interact with liquids is often required in domains such as chemical industry or nanotechnology, but so far nobody succeeded to describe these interactions in simple mathematical formulas. Every time scientists tried to explain the phenomenon through experiments in this field, calculations b... |

NEC, the Japanese electronics manufacturer, recently unveiled a new concept phone that uses fuel cell as power. While the idea is not new, as Motorola, Samsung and Toshiba also consider implementing this technology into handsets, NEC's fuel cell phone is really something that we haven't seen until now. ... |

All soft drinks that you ingest are artificial. They contain an array of synthetic added products. Do you really know what sh*t you are drinking? A new report by the EPA (U. S. Environmental Protection Agency) and the U.S. Food and Drug Administration (FDA), to be published in the ACS' Journal of Agricultural an... |

We know now that Mars had flowing water on its surface once, and that it still has some water trapped on its surface in the form of ice. However, scientists have recently discovered that Mars might still have some water flowing of its surface. This comes as a result of a study made by professor Berry Lyons, from the ... |

An experiment conducted by a team from the University of Chicago reported a surprising discovery. Grains of sand can behave in a liquid manner under the right conditions. These kinds of experiments are designed to simulate the birth of the universe and the way matter moved in the first seconds after the Big Bang.In t... |

Sun Microsystems just received its patent for a radical new cooling solution that uses a metal heatsink coupled with a closed circuit fluid system that is moved through the use of magneto-hydrodynamic technology. While there are many cooling solutions for computers that are using the heat pipe concept, this system is... |

Even if water is one of the most important and abundant molecules on Earth, it has unique traits, determined by hydrogen bonds, that still puzzle scientists. A recent research found a new one. "The interaction of water with electric fields has been intensely explored over the last years. We report another unusual ef... |

Guys love beer and that can be easily seen in beer ads, where besides the actual product, you can see all kinds of sports and beautiful women, mostly naked or who are about to lose their clothes to the happy owner of a can/pint.But there is more to beer than meets the eye. Many interesting stories circulating on the... |

Glass, even the one used in windows, has always fascinated scientists and not only due to its transparency. Like other solids, such as acrylic and polycarbonate, glass has a weird structure, which is not crystalline but disordered at the atomic scale.Essentially, glass is a liquid frozen in time. This freezing, howe... |

A newly developed technology could revolutionize most optical devices, making them much more adaptable, yet smaller and cost-effective. The variable liquid lenses and mirrors may one day replace conventional ones in camera phones, for instance, as they have no mechanical parts - thus taking less space - but maintain... |

A new discovery in the field of nanotechnology could produce the smallest "engines" in the world. The best part is that scientists will be able to remotely control them using rays of UV light that make a group of bacteria push the nanomachines both in straight line and on curved trajectories.Researchers led by Min J... |

Nanotechnology is full of surprises and new applications are discovered every day. One of the most unusual is the recent experiment of a team of scientists who were able to make a magnet change the color of a liquid, turning it from coffee-brown to orange, then green and finally dark blue.The liquid is actually a so... |

Plastics are made of semisynthetic polymerization products composed of organic condensation or addition polymers and may contain other substances to improve performance or economics. Their widespread use made them indispensable in almost all industry areas.There are methods by which plastics can be broken back down... |

Lenses are used to converge or diverge light in various optical and electronic devices and the first written records of the use of a lens date to Ancient Greece, in 424 BC. The optical zoom lenses in professional television cameras can have a magnification ratio as high as 100x.A group of scientists claim to have cr... |

What happens when you stick a knife into a solid material and drag it through? A cleavage splits the two sides of the material, leaving a visible trace of the knife. And when you do that to a fluid? Of course, the fluid behind the knife will get back to its original state and the two sides will reunite.However, natu... |

Anyons are exotic particles that exist in two-dimensional quantum liquids. A quantum liquid (fluid) is a state of matter where, under very high pressures and low temperatures, electrons condense, thus theoretically allowing electrical current to flow forever with a complete absence of voltage.They remain liquid at a... |

A team of Japanese chemists led by Kazuki Sada of Kyushu University have developed a new gel that can increase its volume 500 times when coming in contact with solvents.A gel is a colloidal system in which a porous network of interconnected nanoparticles spans the volume of a liquid medium. In general, gels are appa... |

Everybody knows water is essential to all known forms of life, or that it covers almost three quarters of Earth's surface. It is found mostly in liquid state, but the other states, solid (ice) and gaseous (vapor), and their behavior were also well known to scientists.Well, it seems we didn't know everythin... |

How many coolers does your PC have? 1, 2, 3...more? How about none, and without catching fire or melting?Almost all microprocessors inside servers, desktops and laptops are normally cooled using fans that blow air across the components. There is a company called Very-PC, that hopes to see a much more radical, oil-ba... |

Until now, the only known ways to move liquid were to apply pressure from a mechanical source, like an object or an other liquid or gas, but it seems that scientists have figured out how to create a jet of liquid with nothing but the power of light: they shined a laser beam through a soapy liquid, producing a long j... |

New measurements of Mars' south polar region indicate extensive frozen water, but could it be more to it than we presently now? Actually, the polar region contains enough frozen water to cover the whole planet in a liquid layer of approximately 11 meters (36 feet) deep. These south polar layers cover an area big... |
