| Plant-made drug reverses breathing paralysis, study suggests Posted: 13 Jul 2013 09:28 AM PDT Paralytic drugs like succinylcholine are often used during surgery or when critically ill patients require endotracheal intubation. But if the drug is not swiftly cleared from the patient's system, the results can be deadly.  |
| Disks don't need planets to make patterns, NASA study shows Posted: 13 Jul 2013 06:52 AM PDT Many young stars known to host planets also possess disks containing dust and icy grains, particles produced by collisions among asteroids and comets also orbiting the star. These debris disks often show sharply defined rings or spiral patterns, features that could signal the presence of orbiting planets. Astronomers study the disk features as a way to better understand the physical properties of known planets and possibly uncover new ones.  |
| Posted: 13 Jul 2013 06:52 AM PDT Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work identifies an important component for regulating stem cell niches, with impacts on tissue building and function. The results could have implications for disease research.  |
| Sculpting flow: Supercomputers help microfluidics researchers make waves at the microscopic level Posted: 12 Jul 2013 01:10 PM PDT Researchers have discovered a new way of sculpting tailor-made fluid flows by placing microscale pillars in microfluidic channels. The method could allow clinicians to better separate white blood cells in a sample, increase mixing in industrial applications, and more quickly perform lab-on-a-chip-type operations.  |
| Surprising benefits about dairy cow inflammation Posted: 12 Jul 2013 07:28 AM PDT A new study finds surprising benefits about dairy cow inflammation, including benefits to late pregnancy and lactation.  |
| Injecting iron supplement lets scientists track transplanted stem cells Posted: 12 Jul 2013 05:46 AM PDT A new, noninvasive technique for tracking stem cells after transplantation -- developed by a cross-disciplinary team of radiologists, chemists, statisticians and materials scientists -- could help surgeons determine whether a procedure to repair injured or worn-out knees is successful.  |
| A hidden epidemic: Street children show high levels of drug use Posted: 12 Jul 2013 05:46 AM PDT A review of fifty studies of drug use among street children in 22 countries sheds new light on the magnitude of the problem, the causes and health consequences of drug use among street children.  |
| How to build your gate: Decade-old controversy over structure of nuclear pore solved Posted: 12 Jul 2013 05:43 AM PDT A decade-old controversy over the structure of the nuclear pore has been solved, thanks to a new method which combines thousands of super-resolution microscopy images to reach a precision of less than one nanometer.  |
