| Lasers light the path to neuron regeneration Posted: 19 Sep 2011 04:40 PM PDT Lasers have been used to fabricate tiny scaffolds to be used as delivery vehicles to drop cells off at damaged locations and help treat diseases such as Alzheimer's and Parkinson's.  |
| 'Inexhaustible' source of hydrogen may be unlocked by salt water, engineers say Posted: 19 Sep 2011 12:13 PM PDT A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, according to engineers.  |
| Engineers use short ultrasound pulses to reach neurons through blood-brain barrier Posted: 19 Sep 2011 12:13 PM PDT Researchers have developed a new technique to reach neurons through the blood-brain barrier and deliver drugs safely and noninvasively. Up until now, scientists thought long ultrasound pulses, which can inflict collateral damage, were required. This new study shows that extremely short pulses of ultrasound waves can open the blood-brain barrier -- with the added advantages of safety and uniform molecular delivery -- and the molecule injected systemically could reach and highlight the targeted neurons noninvasively.  |
| NASA's WISE raises doubt about asteroid family believed responsible for dinosaur extinction Posted: 19 Sep 2011 11:40 AM PDT Observations from NASA's Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping open the case on one of Earth's greatest mysteries.  |
| Black hole, star collisions may illuminate universe's dark side Posted: 19 Sep 2011 09:18 AM PDT Researchers have unveiled a ready-made method for detecting the collision of stars with an elusive type of black hole that is on the short list of objects believed to make up dark matter. Such a discovery could serve as observable proof of dark matter and provide a much deeper understanding of the universe's inner workings.  |
| Brightest gamma ray on Earth -- for a safer, healthier world Posted: 19 Sep 2011 08:38 AM PDT The brightest gamma ray beam ever created -- more than a thousand billion times more brilliant than the sun -- has been produced in research that could open up new possibilities for medicine. Physicists have discovered that ultra-short duration laser pulses can interact with ionized gas to give off beams that are so intense they can pass through 20 cm of lead and would take 1.5 m of concrete to be completely absorbed. The ray could have several uses, such as in medical imaging, radiotherapy and radioisotope production for PET (positron emission tomography) scanning. The source could also be useful in monitoring the integrity of stored nuclear waste.  |
| Catching a breath -- wirelessly: Noninvasive method to watch for SIDS, help surgery patients Posted: 19 Sep 2011 04:42 AM PDT Engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome (SIDS).  |
