Solar flare: Space weather disrupts communications, threatens other technologies (February 18, 2011) -- A powerful solar flare has ushered in the largest space weather storm in at least four years and has already disrupted some ground communications on Earth. ... > full story
Chemical guided missile could be the answer to wiping out cancer (February 18, 2011) -- Medical scientists in Australia have created the world's first cancer stem cell-targeting chemical missile, placing them a step closer to creating a medical 'smart bomb' that would seek out and eradicate the root of cancer cells. ... > full story
Hydrogen cartridges fuel laptops and phones for outdoor enthusiasts (February 18, 2011) -- Scientists have developed new hydrogen cartridges, which provide energy to fuel cells designed to recharge cell phones, laptops and GPS units. The green power source is geared toward outdoor enthusiasts as well as residents of the Third World, where electricity in homes is considered a luxury. ... > full story
The real avatar: Swiss researchers use virtual reality and brain imaging to hunt for the science of the self (February 18, 2011) -- That feeling of being in, and owning, your own body is a fundamental human experience. Now, researchers have announced an important step in decoding the phenomenon. By combining techniques from cognitive science with those of virtual reality and brain imaging, scientists in Switzerland are narrowing in on the first experimental, data-driven approach to understanding self-consciousness. ... > full story
World's first anti-laser built (February 18, 2011) -- More than 50 years after the invention of the laser, scientists have built the world's first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology. ... > full story
Compact high-temperature superconducting cables demonstrated (February 18, 2011) -- A researcher has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current. The compact cables could be used in the electric grid as well as scientific and medical equipment and may enable HTS power transmission for military applications. ... > full story
The green machine: Algae clean wastewater, convert to biodiesel (February 18, 2011) -- Researchers are developing biodiesel from microalgae grown in wastewater. The project is doubly "green" because algae consume nitrates and phosphates and reduce bacteria and toxins in the water. The end result: clean wastewater and stock for a promising biofuel. ... > full story
Catching space weather in the act (February 18, 2011) -- Special cameras aboard the Interstellar Boundary Explorer, or IBEX, spacecraft have snapped the first shots of a complex space environment. Instead of recording light, these two large single-pixel cameras detect energetic neutral atoms. ... > full story
Controlling a computer with thoughts? (February 18, 2011) -- Researchers will place brain-computer interfaces in patients with spinal cord injuries to test if it is possible for them to control external devices, such as a computer cursor or a prosthetic limb, with their thoughts. ... > full story
Sleeping Trojan horse to aid imaging of diseased cells (February 18, 2011) -- A unique strategy developed by researchers in the UK is opening up new possibilities for improving medical imaging. Medical imaging often requires getting unnatural materials such as metal ions into cells, a process which is a major challenge across a range of biomedical disciplines. One technique currently used is called the 'Trojan Horse' in which the drug or imaging agent is attached to something naturally taken up by cells. ... > full story
Improving microscopy by following the astronomers' guide star (February 18, 2011) -- A corrective strategy used by astronomers to sharpen images of celestial bodies can now help scientists see with more depth and clarity into the living brain of a mouse. ... > full story
New method for unraveling molecular structures (February 18, 2011) -- Chemists in Germany have introduced a new method for identifying chemical compounds. The approach they used is an improvement on nuclear magnetic resonance (NMR) measurements -- for decades one of the most successful methods for determining the chemical structure of organic molecules. The results show a sophisticated approach to structural data when classical methods of analysis fail. ... > full story
