A Flexible Approach To New Computer Displays
- ScienceDaily
- 08/6/5 16:34
Flat screen displays currently used in computer monitors, television sets and numerous other electronic devices are all built on a glass base. Most use liquid crystal devices (LCDs), which filter light from behind to form an image. But the glass substrate makes LCD displays rigid and fragile, limiting their use. Now display manufacturers are working to develop a new generation of robust, flexible...
Are Panic And Inability To Express Emotions Related?
- ScienceDaily
- 08/6/5 16:34
Investigators have explored the inability to express emotions (alexithymia) in panic disorder in an article in Psychotherapy and Psychosomatics. In patients with panic disorder (PD), the difficulty to identify and manage emotional experience might contribute to the enduring vulnerability to panic attacks. Such a difficulty might reflect a dysfunction of fronto-temporo-limbic circuits. The present...

Could Nanotechnology End Cartilage Loss?
- ScienceDaily
- 08/6/5 16:34
Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections. Now nanotechnology engineers have shown, for the first time, how a surface of carbon nanotubes combined with...

Laboratory tests and field studies continue to show promise that probiotic bacteria can be used to help amphibian populations, including the endangered yellow-legged frog, fend off lethal skin diseases.
Scientists Uncover How Plant Roots Respond To Physical Forces Such As Gravity, Pressure, Or Touch
- ScienceDaily
- 08/6/5 16:34
Researchers have identified two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery.
Neurologically Impaired Mice Improve After Receiving Human Stem Cells
- ScienceDaily
- 08/6/5 16:34
Scientists report a dramatic success in what may be the first documented rescue of a congenital brain disorder by transplantation of human neural stem cells. The research may lead the way to new strategies for treating certain hereditary and perinatal neurological disorders.
Nutritional Supplement Could Improve Clinical Situation Of ICU Patients
- ScienceDaily
- 08/6/5 16:34
For the first time, it has been determined the exact quantity of vitamins A, E and C and minerals needed to improve the clinic situation of critical patients. This study suggests that the oxide stress increase during patients stays in the Intensive Care Unit is due to the low levels of antioxidant food...
A Molecular 'Salve' To Soothe Surface Stresses
- ScienceDaily
- 08/6/5 14:00
A single layer of molecular 'salve' can significantly soothe the stresses affecting clean metal surfaces. The discovery may help scientists to understand the factors that influence surface stress, which is important in a broad array of applications from chemical and biological sensors to semiconductor manufacturing and metal...
Knowing Looks: Using Gaze Aversion To Tell When Children Are Learning
- ScienceDaily
- 08/6/5 14:00
People use eye contact in a variety of ways every minute of every day but how often do you find yourself staring into space with concentrating on an issue or problem? Psychologists now know that people who are carrying out a complex task tend to look away from anyone else who is nearby. They refer to it as "gaze...
Memory In Honeybees: What The Right And Left Antenna Tell The Left And Right Brain
- ScienceDaily
- 08/6/5 14:00
The idea that all vertebrate species, even nonhuman ones without any linguistic skills, have an asymmetric brain seems to be finally accepted. Now brain lateralization has been extended beyond the class Vertebrata. Insects, with their nervous system so different from that of vertebrates, are also...
Microsurgery On Fruit Fly Brain Leads To New Insights Into Irreparable Nerve Injuries
- ScienceDaily
- 08/6/5 14:00
Every year, millions of people are confronted with potentially irreparable brain or spinal cord injuries resulting from traffic accidents. Because the nerves in a damaged spinal cord cannot, or cannot fully, be repaired, the patient remains (partially) paralyzed. Now, scientists have successfully developed a simple model that enables the study of injured brain...
