Go with the flow: How cells use biological flows to signal and organize
An EPFL (Ecole Polytechnique Federale de Lausanne) team led by professor Melody Swartz has demonstrated for the first time that the presence of very slow biological flows affects the extracellular environment in ways that are critical for tissue formation and cell migration. view more (2005-10-25)
Hammering sheet metal into shape
The tool at the pressing plant resonantly pounds the sheet metal, ejecting the newly formed vehicle hood moments later. Although this operation runs like clockwork on the production line, it caused the developers of the metal-forming equipment many a headache, since sheet metal springs back (unbends elastically) when the press is opened. The... view more... (2003-02-20)
Why exercising muscles tire when needed most
The cause of muscle fatigue during intense exercise is linked directly to the muscle's reliance on anaerobic metabolism for force production, according to a new study by researchers at Rice and Harvard universities. view more (2006-11-09)
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)
MIT solves 100-year-old engineering problem
As a car accelerates up and down a hill then slows to follow a hairpin turn, the airflow around it cannot keep up and detaches from the vehicle. This aerodynamic separation creates additional drag that slows the car and forces the engine to work harder. The same phenomenon affects airplanes, boats, submarines, and even your golf ball. view more (2008-09-26)
Examination of radiation left from birth of universe could alter theories
Using relic radiation from the birth of the universe, astrophysicists at the University of Illinois have proposed a new way of measuring the fine-structure constant in the past, and comparing it with today. view more (2007-04-03)
Scientists unlock more secrets of HIV and SARS
UK scientists have cracked one of the key biological processes used by viruses such as HIV and SARS when they replicate. view more (2006-05-11)
Gamma-ray photon race ends in dead heat; Einstein wins this round
Racing across the universe for the last 7.3 billion years, two gamma-ray photons arrived at NASA's orbiting Fermi Gamma-ray Space Telescope within nine-tenths of a second of one another. view more (2009-10-29)
When means become ends - considering the impact of patent strategy on innovation
The patent system is meant to encourage innovation. It may be doing no such thing. It may actually be discouraging innovation. The patent is meant to help patent holders turn their inventions into innovations. But the patent can also be used to prevent the competition innovating. The problem arises from the success of efforts to increase both the... view more... (2003-07-29)
Keeping an eye on fatigue in wind turbines
Wind farms are springing up everywhere like mushrooms. Business in this alternative sector of the energy industry is booming, thanks in part to federal and former state subsidies. The total output of the wind turbines installed in Germany today is theoretically enough to supply the whole capital of Berlin with electricity. But the durability of... view more... (2003-09-18)
Satellite reveals surprising cosmic 'weather' at edge of solar system
The first solar system energetic particle maps show an unexpected landmark occurring at the outer edge of the solar wind bubble surrounding the solar system. view more (2009-10-19)
New insight into joint lubrication that keeps osteoarthritis at bay
New evidence to explain how the body's natural joint lubricant prevents the wear and tear that can lead to osteoarthritis has been uncovered by researchers at Duke University's Pratt School of Engineering The findings may lead to new methods for treating arthritis, the researchers said. view more (2006-03-29)
Coral reefs are increasingly vulnerable to angry oceans
Size and shape may predict the survival of corals around the world when the weather churns the oceans in the years to come, according to a new model that relies on engineering principles. view more (2006-11-27)
Lung damage in babies with congenital heart disease under study
Trying to understand and stop the collateral lung damage that can occur in babies with congenital heart disease is the focus of a new study. view more (2008-03-11)
A single water molecule acting as gate keeper
How do the bonds cells form with their environments rupture? What enables some cells to migrate? It is known since quite a while that cells can have complex mechanical interactions with their environments. Not only the biochemical but also the physical properties of their environment can thus have significant impact on cell behavior and even gene... view more... (2004-11-12)
Bent tectonics
More than 80 undersea volcanoes and a multitude of islands are dotted along the Hawaii-Emperor seamount chain like pearls on a necklace. A sharp bend in the middle is the only blemish. view more (2009-04-03)
Mathematical Model Shows Why Defeating Insurgent Groups Like Taliban is So Difficult
Insurgent groups like the Taliban can only be effectively engaged with timely and accurate military intelligence, and even good intelligence may only succeed in containing the insurgency, not defeating it. view more (2009-07-17)
University of Minnesota researchers take new look at cellular suicide
Like a bodyguard turned traitor, a protein whose regular job is to help repair severed DNA molecules will, in some cases, join forces with another protein to do the opposite and chop the DNA to bits. view more (2006-07-07)
Protein 'nanosprings' most resilient found in nature
A component of many proteins has been found to constitute one of the most powerful and resilient molecular "springs" in nature, researchers have discovered. view more (2006-01-16)
The first results of Finuda will be announced on January 30th: a new window for the study of exotic atomic nuclei.
On Friday the 30th, during the XLII international winter meeting on nuclear physics at Bormio, the first results will be announced of Finuda experiment (Nuclear Physics at Daphne), settled in Frascati at Infn National Laboratories. Planned and made operating by a group of about forty physicists from Universities and Infn Sites of Bari, Brescia,... view more... (2004-01-29)
