...The revolutionary product design required careful selection of materials. A strong synthetic sits on top of the gel-like lubricant to form a protective layer across the surface of the helmet. State-of -the-art vacuum casting was used to create prototypes and the materials tested for resistance and strength. The chosen synthetic stretched up to eight times its original length."

Low IQ among strongest predictors of cardiovascular disease -- second only to cigarette smoking in large population study
While lower intelligence scores -- as reflected by low results on written or oral tests of IQ -- have been associated with a raised risk of cardiovascular disease, no study has so far compared the relative strength of this association with other established risk factors such as obesity, smoking and high blood pressure. Now, a large study funded by Britain's Medical Research Council, which set out to gauge the relative importance of IQ alongside other risk factors, has found that lower intelligence scores were associated with higher rates of cardiovascular disease and total mortality at a greater level of magnitude than found with any other risk factor except smoking.

The man was one of 23 patients diagnosed as being in a vegetative state and recruited for a three-year study by Medical Research Council (MRC) scientists in Cambridge and colleagues from the University of Liège in Belgium.
Its aim was to see if brainscans could detect signs of awareness in patients who were thought to be closed off from the world.
Functional magnetic resonance scanning (fMRI) was used to measure activity in "motor" and "spatial" brain regions while the patients were asked to imagine specific scenes.
The scans use magnetic fields and radiowaves to detect surges of bloodflow that accompany neural activity.
For the "motor" task, patients were asked to imagine standing still on a tennis court and swinging an arm to return balls from an instructor. To activate the "spatial" region, they had to imagine navigating the streets of a familiar city or walking from room to room in their home.
In four cases, the scans were able to detect activity in the appropriate brain region as the patients carried out the scientists' verbal instructions.
But one Liège patient who had produced reliable responses was singled out for an even more remarkable test. He was asked to use "motor" or "spatial" imagery as "yes" and "no" answers to questions. The patient responded accurately to five out of six autobiographical questions posed by the scientists.
On one occasion he was asked "Is your father's name Alexander?" and correctly answered "Yes" by imagining the tennis scene. When he was asked "Is your father's name Thomas?", he answered "No" by thinking about roaming streets or walking around the house.
"Not only did these scans tell us that the patient was not in a vegetative state but, more importantly, for the first time in five years, it provided the patient with a way of communicating his thoughts to the outside world."

Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. Research on the product was carried out at the Saarbrücken Institute for New Materials. Nanopool is already in negotiations in the UK with a number of companies and with the National Health Service, with a view to its widespread adoption.
The liquid glass spray produces a water-resistant coating only around 100 nanometers (15-30 molecules) thick. On this nanoscale the glass is highly flexible and breathable. The coating is environmentally harmless and non-toxic, and easy to clean using only water or a simple wipe with a damp cloth. It repels bacteria, water and dirt, and resists heat, UV light and even acids. UK project manager with Nanopool, Neil McClelland, said soon almost every product you purchase will be coated with liquid glass.
Food processing companies in Germany have already carried out trials of the spray, and found sterile surfaces that usually needed to be cleaned with strong bleach to keep them sterile needed only a hot water rinse if they were coated with liquid glass. The levels of sterility were higher for the glass-coated surfaces, and the surfaces remained sterile for months.
Other organizations, such as a train company and a hotel chain in the UK, and a hamburger chain in Germany, are also testing liquid glass for a wide range of uses. A year-long trial of the spray in a Lancashire hospital also produced “very promising” results for a range of applications including coatings for equipment, medical implants, catheters, sutures and bandages. The war graves association in the UK is investigating using the spray to treat stone monuments and grave stones, since trials have shown the coating protects against weathering and graffiti. Trials in Turkey are testing the product on monuments such as the Ataturk Mausoleum in Ankara.
