Audi RS7: An Autonomous Car That Reaches 240 km/h

Audi showed the RS7, an autonomous model that was able to reach 239 km / h in a closed circuit in Germany.

One of the advantages of autonomous cars is that they can get from point A to point B, without the intervention of a human being. Since it is not a person who is behind the wheel, the odds are minimized caused by human error, such as tiredness, sleep or distraction. Under these conditions, theoretically it will be safe to travel at speeds much higher than those that are currently legally permitted. And with that assumption is that the Audi RS7 presented an autonomous model capable of reaching 240 km / h, reports Popular Science.

The car manufacturer has tested this model in a closed circuit in Germany and then put a human pilot to do the same circuit. The driver took five seconds longer than the autonomous car. Still do not know pricing or release dates for this model.

Robot Performs Brain Surgery To Prevent Epileptic Seizures

American researchers are working on a prototype that is capable of performing brain surgery for epilepsy patients safer and less invasive. Not all patients with epilepsy can control their attacks through medication, so some have to resort to brain surgery. This option is invasive and requires that the patient part of the brain is removed, disconnected or stimulated, with the consequent recovery may take three months.

Now, researchers at Vanderbilt University have announced that they have spent the last five years to develop a robot that is able to do this surgery for a faster, less invasive and requires less recovery time. According to CNet, this robot was created by David Comber and Eric Barth, student and professor, respectively, mechanical engineering, and can enter the brain by inserting a needle 1.14 mm on the cheek of the patient, which prevents puncture the skull . Note that this equipment must be operated from a machine MRIs.

The next step will be to test the robot in cadavers, and the researchers hope to have ready to be in the operating room equipment within a decade.

Lowest Temperature Ever In Universe Recorded At Italian Laboratory

Scientists at National Nuclear Physics Institute's Gran Sasso National Laboratory, Italy have set a world record of the lowest temperature ever achieved in the universe. They cooled a copper vessel with a volume of one cubic meter to -273.144 degrees celsius. This is stunningly close to 'absolute zero', which is equal to -273.15 degrees celsius. Theoretical physics says that temperature can never go below this limit.

No experiment on Earth has ever cooled a similar mass or volume to temperatures such a low; similar conditions are also not expected to arise in nature. This gives CUORE the distinction of being the coldest cubic meter in the known universe. The cooled copper mass, weighing approximately 400 kg, was the coldest cubic meter in the universe for over 15 days.
