A sticky business -- how cancer cells become more 'gloopy' as they die
The viscosity, or 'gloopiness', of different parts of cancer cells increases dramatically when they are blasted with light-activated cancer drugs, according to new images that provide fundamental insights into how cancer cells die, published in Nature Chemistry today (15 March). view more (2009-03-16)
Obtaining high performance coatings through simple latex film simulations
In the formation of high performance coatings, it is known that the process whereby a film forms from a colloidal dispersion is a key step. view more (2005-11-28)
Making thick Ketchup
Specialists of the Moscow company "IZOBRETATEL" ("Inventor") have designed and patented a new device - the consistence express analyzer. The designers do not assert that their device will cause a revolution in science. They do not even state that they have developed a device for scientific research. However, this simple device... view more... (2003-07-18)
Magnetorheological fluids set to revolutionise dynamic vehicle suspension systems
Magnetorheological (MR) fluids are smart materials whose flow/viscosity properties can be modified by applying an electric field. view more (2005-11-30)
Viscosity-enhancing nanomaterials may double service life of concrete
Engineers at the National Institute of Standards and Technology (NIST) are patenting a method that is expected to double the service life of concrete. view more (2009-02-12)
Water flows like molasses on the nanoscale
A Georgia Tech research team has discovered that water exhibits very different properties when it is confined to channels less than two nanometers wide - behaving much like a viscous fluid with a viscosity approaching that of molasses. view more (2007-04-25)
Butterfly proboscis to sip cells
A butterfly's proboscis looks like a straw -- long, slender, and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University. He hopes to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells. view more (2009-11-23)
Hyperviscous fluids: Better treatment for severe blood loss
Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. view more (2008-04-29)
Friction Inside The Earth Is A Source Of Heat
There is high temperature inside our planet and the reason is not known yet. A common belief that the Earth`s interior is heated by radioactive elements is now doubted of. Professor Felix Letnikov from Irkutsk Institute of the Earth`s Crust have proposed an idea that the heat is formed in the outer core because of friction between its layers.... view more...

'Electrospray' droplet research yields surprising, practical results
Chemical engineers at Purdue University are the first to mathematically describe precisely how droplets form when liquids are exposed to electric fields, an advance that could have applications in areas ranging from manufacturing to medical diagnostics. view more (2008-01-08)
Physicists create a 'perfect' way to study the Big Bang
Physicists have created the state of matter thought to have filled the Universe just a few microseconds after the big bang and found it to be different from what they were expecting. Instead of a gas, it is more like a liquid. Understanding why it is a liquid should take physicists a step closer to explaining the earliest moments of our Universe. view more (2005-07-21)
Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. view more (2005-12-06)
Fluidizing infant gruels with amylase to improve their nutritional value
The growth problems which affect the children of the countries of the South are attributable, among other causes, to insufficient and inappropriate complementary feeds. Such supplements are mainly composed of gruels made with flour from locally grown cereals mixed with water. Rich in starch, these gruels thicken and swell when cooked. Mothers... view more...

Atomic force microscopy reveals liquids adjust viscosity when confined, shaken
Getting ketchup out of the bottle isn't always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated. The opposite is not typically true - a liquid such as water does not become a gel when shaken. view more (2008-04-30)
New molecules with many branches will help unleash potential of nanotechnology
Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. view more (2008-10-27)
Gifted Kids Explore the Vile Side of Medicine by Studying the Science of Snot and Vomit
Students from the National Academy of Gifted and Talented Youth (NAGTY), at the University of Warwick, will explore the vile side of medical science by examining snot and vomit as part of an outreach event on Saturday 17th January at 2 Donegal Street, Islington, London, entitled 'Rude Science', which looks at the unpleasant side of the human body.... view more...

How Do Bacteria Swim? Brown Physicists Explain
Imagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim. view more (2008-11-20)
Mucolytic drugs may benefit patients with severe pulmonary disease
Mucolytic drugs may benefit patients with severe pulmonary disease (Oral mucolytic drugs for exacerbations of chronic obstructive pulmonary disease: systematic review) BMJ Volume 322, pp 1271-1274 Patients who suffer frequent, prolonged or severe recurrences of chronic bronchitis and chronic obstructive pulmonary disease (COPD) may benefit from... view more...

Researchers link jellyfish, other small sea creatures to large-scale ocean mixing
The ocean's smallest swimming animals, such as jellyfish, can have a huge impact on large-scale ocean mixing, researchers have discovered. view more (2009-07-30)
Microorganisms helps us to drive more oil from the oil-bearing bed
When the reservoir pressure drops the oil field dries up though there is a lot of oil. To pump out the remains one has to apply pressure by pumping into the oil-bearing bed water or gas. Other method - to apply biotechnology. The oil is contaminated with specially bred mi-croorganism strains, which produce gas, acids and surface active agents... view more... (1999-08-18)
