New insights into how stem cells determine what tissue to become
An immunofluorescence image of a human mesenchymal stem cell growing on a plate of microposts, which have the approximate consistency of Silly Putty. This image was taken after one day of culturing. The red dots are the microposts, which are relatively short in this sample. The green is the cell and the blue is its nucleus.

Scientists theorize why volcano erupts
Scientists theorize why volcano erupts
CAMBRIDGE, Mass. Understanding the processes that cause volcanic eruptions can help scientists predict how often and how violently a volcano will erupt. Although scientists have a general idea of how these processes work - the melting of magma below the volcano causes liquid magma and gases to force their way to Earth's surface ' eruptions happen so rarely, and often with little warning, that it can be difficult to study them in detail.

Not a drag: breakthrough will create cleaner, faster planes
A world first model for predicting fluid flows close to surfaces will enable engineers to reduce drag in vehicles, and in turn, lead to more efficient and greener planes, cars and boats, according to a University of Melbourne study. Research team leader and Federation Fellow Professor Ivan Marusic from the Department of Mechanical Engineering at the University of Melbourne says skin-friction drag accounts for 50 per cent of fuel expenditure in aircraft, so even modest reductions in drag would save money and significantly reduce carbon emissions.

World first for quantum memory storage
World first for quantum memory storage
An ANU-led team has developed the most efficient quantum memory for light in the world, taking us closer to a future of super-fast computers and communication secured by the laws of physics. The team at the ANU Research School of Physics and Engineering used a technique they pioneered to stop and control light from a laser, manipulating electrons in a crystal cooled to a chilly -270 degrees Celcius.

Schooling Fish Offer New Ideas for Wind Farming
The quest to derive energy from wind may soon be getting some help from California Institute of Technology (Caltech) fluid-dynamics expert John Dabiri-and a school of fish. As head of Caltech's Biological Propulsion Laboratory, Dabiri studies water- and wind-energy concepts that share the theme of bioinspiration: that is, identifying energy-related processes in biological systems that may provide insight into new approaches to-in this case-wind energy.

New microscopy technique reveals mechanics of blood cell membranes
New microscopy technique reveals mechanics of blood cell membranes
CHAMPAIGN, Ill. Thanks to an interdisciplinary team of researchers, scientists now have a more complete understanding of one of the human body's most vital structures: the red blood cell. Led by University of Illinois electrical and computer engineering professor Gabriel Popescu, the team developed a model that could lead to breakthroughs in screening and treatment of blood-cell-morphology diseases, such as malaria and sickle-cell disease.

Tiny Gold Particles Help Researchers Find Protein Impostor
March 31, 2010 — Coral Gables — University of Miami assistant professor in the College of Engineering, Na Li and her collaborators have developed a fast, economical and easy method to detect melamine in milk. Melamine is the compound found in contaminated pet food and in tainted dairy products from China in 2007 and 2008 respectively.

MIT analysis suggests wind turbines could cause temperatures to rise and fall
Turbines installed in water could cause drop in temperature; land turbines could cause rise MIT analysis suggests wind turbines could cause temperatures to rise and fall New microscopy technique offers close-up, real-time view of cellular phenomena CAMBRIDGE, Mass. Although wind power has emerged as a viable renewable energy source in recent years ? one that proponents say could lessen the threat of global warming ? a new MIT analysis may serve to temper enthusiasm about wind power, at least at very large scales.

Princeton scientist makes a leap in quantum computing
Princeton scientist makes a leap in quantum computing
Jason Petta, an assistant professor of physics, has found a way to alter the property of a lone electron without disturbing the trillions of electrons in its immediate surroundings. Such a feat is an important step toward developing future types of quantum computers.

Engineers Invent New Process to Make Foundries Greener
Engineers at the University of Birmingham, with local company, Ntec, have invented a new casting process that could reduce the energy costs of light-metal foundries. The technology, called CRIMSON, means that foundries need only heat the quantity of metal required to fill a single mould rather than whole batches that use unnecessary energy and create waste.

Testfahrten eines Marsmobils im High-Tech-Sandkasten
Oerlikon Space is currently testing an autonomous robotic vehicle for Mars; in the year 2015, as part of its ExoMars scientific mission, the European Space Agency (ESA) plans to land an autonomous robot of this type on the Red Planet to search for signs of life there.
