A Flexible Approach To New Computer Displays

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?

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...

Venus Express Reveals New Details On Venusian Clouds

As ESA's Venus Express orbits our sister planet, new images of the cloud structure of one of the most enigmatic atmospheres of the Solar System reveal brand-new details. Venus is covered by a thick layer of clouds that extends between 45 and 70 km above the surface. These rapidly-moving clouds are mainly composed of micron-sized droplets of sulphuric acid and other aerosols (fine solid or liquid...

Could Nanotechnology End Cartilage Loss?

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...

A Molecular 'Salve' To Soothe Surface Stresses

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...

UK Medics Solve Ancient Riddle Of 'Finger Clubbing'

A puzzling medical condition, identified more than 2,000 years ago by Hippocrates, has finally been explained by researchers at the University of Leeds. The phenomenon of "finger clubbing", a deformity of the fingers and fingernails, has been known for thousands of years, and has long been recognized to be a sign of a wide range of serious diseases -- especially lung...

Blocking Signaling Protein Prevents Prostate Cancer Spread, Scientists Find

Researchers have shown that by blocking a signaling protein, they can prevent prostate cancer cells from metastasizing. In a series of experiments in both the laboratory and animal models, they found that the protein, Stat3, is key to the metastatic progression of prostate cancer. The work opens the door to studies examining the protein as a target for therapies to keep prostate cancer at...

Human Stem Cells Show Promise Against Fatal Children's Diseases

Scientists have used human stem cells to dramatically improve the condition of mice with a neurological condition similar to a set of diseases in children that are invariably fatal. With a one-time injection of stem cells just after birth, scientists were able to repair defective wiring throughout the brain and spinal cord -- the entire central nervous system -- of mutant "shiverer mice," so...

Kids May Hesitate To Tell Their Doctor, But Will Freely Answer Sex And Drugs Questions On Doctor's Computer Questionnaire

Texting, IM, email -- most kids are comfortable using computers to communicate. It's led to an innovative idea among doctors. Children are given a touch pad and asked a series of questions about topics like sexual activity and depression. Kids hesitate to talk openly to a doctor or in front of a parent, but the study shows they are honest with the computer. That gives doctors more chances to treat...

Rewriting Greenland's Immigration History

The first immigrants in Greenland were not Indians from the North American continent or Canadian Inuit as previously suggested. And it is not just a question of revising the Greenlandic immigration history. The discovery is the world's first successful attempt to sequence an entire mitochondrial genome from an extinct...
