| Nature pulls a fast one on astronomers: Two galaxies caught masquerading as one Posted: 15 Nov 2013 05:18 PM PST What might look like a colossal jet shooting away from a galaxy turns out to be an illusion. New data from the National Science Foundation's Karl G. Jansky Very Large Array (VLA) reveal that two galaxies, one lying behind the other, have been masquerading as one.  |
| New hologram technology created with tiny nanoantennas Posted: 15 Nov 2013 06:49 AM PST Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing.  |
| Organic lights and solar cells straight from the printer Posted: 15 Nov 2013 06:44 AM PST Flickering façades, curved monitors, flashing clothing, fluorescent wallpaper, flexible solar cells – and all printable. This is no make-believe vision of the future; it will soon be possible using a new printing process for organic light-emitting diodes.  |
| Rising concerns over tree pests and diseases Posted: 15 Nov 2013 06:43 AM PST New research has found that the number of pests and disease outbreaks in trees and forests across the world has been increasing. There is growing concern that aspects of globalization - in particular, high volumes and new forms of trade - may increase the risk of disease spreading and provide opportunities for genetic reassortment which can enhance pathogenicity (the ability of an organism to cause disease).  |
| Wireless power transfer for electric vehicles Posted: 14 Nov 2013 09:22 AM PST Engineering researchers have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver -- moving engineers closer to their goal of creating highway "stations" that can recharge electric vehicles wirelessly as the vehicles drive by.  |
| Copper intake makes tumors breathe Posted: 14 Nov 2013 07:25 AM PST Copper imbalances have been associated with a number of pathological conditions, including cancer. Scientists have found that copper in drinking water -- given at the maximum levels permitted in public water supplies -- accelerated the growth of tumors in mice. On the other hand, reducing copper levels reduced tumor growth. The study strongly suggests that copper is an essential factor for the growth of tumors in humans as well.  |
