A fluorescent image of the cell taken four hours into the same experiment. At this time the quantum dot-siRNA complex is distributed throughout the cellular fluid. The dark region in the middle of the cell is the nucleus. Credit: University of Washington New work helps to overcome a long standing barrier in the siRNA (silence/turn …
Sound shield: An acoustic cloak comprising alternating layers of sound-scattering materials should make objects invisible to sonar–and insulated from sound. In this computer-generated image, a cylinder (green circle) is coated with 200 layers of such a material, which was found to be the optimal design. Sound waves moving from left to right (their peaks and …
From Yahoo Sports: The surgery on meniscus in Tiger Wood’s left knee in April didn’t work as well as hope. One knee expert, while obviously not privy to the medical records, watched Woods this weekend and saw trouble. This is not a story related to a “big future”, but it is science and medicine related …
NXP Launches The World’s Fastest Cellular Modem, the PNX6910, which is capable of achieving data transfer rates of 150 Mbits downlink and 50 Mbits uplink, and supports multi-mode LTE/HSPA/UMTS/EDGE/GPRS/GSM capability. The world’s fastest cellular modem from NXP – Nexperia Cellular System Solution PNX6910 will be available to early access customers in the second quarter of …
A transformation in the pace of economic growth can be achieved even without nanofactories. These pre-nanofactory methods would transition well to a world with nanofactories when they do arrive. A coordinated effort by research, companies and government could be made to plan and develop Rapid Automated Manufacturing by 2030. There could be an increase in …
Contour Crafting is an effort to scale up rapid prototyping/manufacturing (a billion dollar industry to make 3 dimensional parts) and inkjet printing techniques to the scale of building multi-story buildings and vehicles. The process could accelerate the trillion dollar (US only) construction industry by 200 times. Projections indicate costs will be around one fifth as …
It is 1.5 meters or 4 feet 9 inches across. The Hyperion Power Generation “nuclear battery” is a self contained, automated, liquid metal nuclear reactor. The company has venture capital funding. Each HPM provides 70 MW thermal energy or 25 MW electric energy via steam turbine for seven to ten years. This amount of energy …
Replacing one amino acid on the surface of a virus that shepherds corrective genes into cells could be the breakthrough scientists have needed to make gene therapy 30 times more efficient. Gene therapy will be a more viable option for treating genetic diseases such as hemophilia. The discovery could be the solution to a problem …
Many environmentalists love to point to public transportation as the blessed technology and policy which would reduce oil consumption and dependence. I agree that increasing public transportation can be helpful, but how helpful and how long would it take to have what level of impact ? In the big energy picture, the USA uses 40% …
Design of an on-chip microscale nanoassembly system has been published by Jason Gorman of the Intelligent Systems Division at the US government’s National Institute of Standards and Technology. They are currently fabricating a somewhat revised micro-scale nanoassembly system that we believe will be capable of manipulating nanoparticles by the end of the summer, 2008. Where …
Microphysiometer using multiwall carbon nanotubes is a major step toward developing the ability to assess the health of the body’s insulin-producing cells in real time. Among other potential applications, this method could be used to improve the efficacy of a new procedure for treating Type 1 (juvenile) diabetes that has demonstrated the ability to free …
