Next generation cars that can think for themselves have clear advantages over flesh-and-blood drivers: they don't get drunk or drowsy, daydream or get distracted by mobile phones and squabbling kids. As the driver is taken out of the equation, so too will a large proportion of accidents.
Worldwide, 1.24 million people die each year in road accidents and as many as 50 million are injured. Human error causes over 90 percent of these collisions.
Driverless cars, which can sense other vehicles on the road as well as obstacles and lane markings, are already proving much safer than human-driven cars. Driverless cars use a mix of GPS, cameras, complex scanners and sensors to detect vehicles, traffic signals, curbs, pedestrians and other obstacles. A central computer system analyzes the data to control acceleration, steering and braking. The software can simulate different eventualities to ensure safety on the road - and the results can be incorporated into the design and production process.
As well as detecting their surroundings using ultrasophisticated mapping systems, future cars will be able to communicate with each other, allowing as many cars as possible to fit on the roads. Connected vehicles will feature safety warnings that alert drivers of potentially dangerous conditions - impending collisions, icy roads and dangerous curves.
Experts say it's not the technology slowing our progress, but legal and practical issues such as who is responsible in the case of an accident, urban infrastructure planning, and the security of car computer systems. Once these details are worked out, and manufacturers have used sophisticated software tools to eliminate all potential problems, it won't be long until we're all a lot safer on the roads.

1) getting people out of the control of the steering wheel should result in fewer accidents. 2) a flesh-and-blood generation of cars has been created that can think for themselves. 3) unlike human beings, driverless cars are not distracted by children or mobile phones. 4) digital technologies have a peripheral importance in the mobility revolution. 5) road accidents claim many lives and most car crashes are caused by human error.

Natural tooth repair method, using Alzheimer's drug, could revolutionise dental treatments
A new method of stimulating the renewal of living stem cells in tooth pulp using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London.
Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and this seals the tooth pulp, but it is insufficient to effectively repair large cavities. Currently dentists use manmade cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning that the normal mineral level of the tooth is never completely restored.
However, in a paper published today in Scientific Reports, scientists from the Dental Institute at King’s College London have proven a way to stimulate the stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements.
The novel biological approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings.
Significantly, one of the small molecules used by the team to stimulate the renewal of the stem cells included Tideglusib, which has previously been used in clinical trials to treat neurological disorders including Alzheimer’s disease.
Using biodegradable collagen sponges to deliver the treatment, the team applied low doses of small molecule glycogen synthase kinase (GSK-3) inhibitors to the tooth. They found that the sponge degraded over time and that new dentine replaced it, leading to complete, natural repair. Collagen sponges are commercially-available and clinicallyapproved, again adding to the potential of the treatment’s swift pick-up and use in dental clinics.
