The video of an accident on the Autobahn in the Netherlands caught on the dashcam of a Tesla Model X shows the Autopilot’s forward collision warning predicting an accident before it could be detected by the driver.

With the release of Tesla’s version 8.0 software update in September, the automaker announced a new radar processing technology that was directly pushed over-the-air to all its vehicles equipped with the first generation Autopilot hardware.

Missions at sea, in mountainous regions or close to skyscrapers are extremely risky for helicopter pilots. The turbulent air flows near oil rigs, ships, cliffs and tall buildings can throw a helicopter off balance and cause a crash. To provide pilots with optimal preparation for these challenging conditions, engineers at the Technical University of Munich (TUM) are developing new simulation software.

Providing helicopter pilots with the best possible preparation for extreme situations: That is the goal of the new simulation software being developed by researchers working at TUM’s Chair of Helicopter Technology. For the first time, real-time computational analysis will be implemented for both fluid mechanics and flight dynamics. “Until now, flight simulators have not adequately reflected the reality of flying in close proximity to large objects,” says Dr. Juergen Rauleder. “The problem is that, when it comes to wind conditions and the response of the helicopter, existing programs follow a rigid pattern. That means that local variations and changing conditions are not taken into account — unless the entire flow environment is known in advance.”

But it is the unforeseen air flows that can be the most treacherous: For example, a moving ship causes air turbulence and sudden local shifts in wind speed known by specialists as “ship airwake flow”. It changes continually through wave action and fluctuating inflow conditions. In addition, turbulence occurs near the deck, the bridge and other ship structures. As a helicopter approaches the ship, there is interference between these air currents and the flow produced by the rotors. Conditions near a mountain slope or next to high buildings are similarly complicated. In all of these cases, the helicopter’s flight characteristics are influenced by complex and overlapping aerodynamic effects.

The relationship between the government and the auto industry is about to be transformed. But into what?

Eight years ago, that relationship hardly could have been more awkward. Two of the Detroit 3 were begging Congress for a lifeline. The federal government would later fire General Motors’ CEO, orchestrate a bankruptcy of GM and Chrysler and emerge as a shareholder in both — a highly un-American arrangement that would lead to a successful recovery, yes, but also lingering tensions and shame.

The relationship is different now, but it’s not necessarily better. The Obama administration shed the stake in the car companies but has wrapped its tentacles more tightly around the industry in many ways, including strict consent decrees to monitor safety and tough targets for fuel economy and greenhouse gas emissions.

Researchers have discovered that tantalum carbide and hafnium carbide materials can withstand scorching temperatures of nearly 4000 degrees Celsius.

Being able to withstand temperatures of nearly 4000°C could pave the way for both materials to be used in ever more extreme environments, such as in heat resistant shielding for the next generation of hypersonic space vehicles.

Tantalum carbide (TaC) and hafnium carbide (HfC) are refractory ceramics, meaning they are extraordinarily resistant to heat. Their ability to withstand extremely harsh environments means that refractory ceramics could be used in thermal protection systems on high-speed vehicles and as fuel cladding in the super-heated environments of nuclear reactors. However, there hasn’t been the technology available to test the melting point of TaC and HfC in the lab to determine how truly extreme an environment they could function in.

LONDON The attack on a Berlin Christmas market showed the devastation that can be wrought by the simple act of driving a truck into crowds, and the problems in preventing another massacre.

The attack in Germany on Monday, in which 11 people were killed by the truck in addition to the murder of the Polish driver, mirrored a militant raid in the French city of Nice in July that killed 86.

Hauliers increasingly track their vehicles in real time but security experts say the technology cannot be used to stop an attack if a lorry has been hijacked to be used as a weapon.

Artificial intelligence (AI) technology has the potential to boost productivity but increase wealth inequality and wipe out millions of jobs, a research report by the White House claimed on Tuesday. With an increasing number of industries set to be affected by automation technology in the coming years, jobs could be displaced — a fear that has been voiced by academics and business leaders. Auto companies are developing driverless cars, and factories are seeing an increased use of robotics.

Because AI is not a single technology, but rather a collection of technologies that are applied to specific tasks, the effects of AI will be felt unevenly through the economy. Some tasks will be more easily automated than others, and some jobs will be affected more than others — both negatively and positively.

Researchers around the world have given varying estimates about the size of potential job losses. One recent estimate by Forrester suggests 6 percent of jobs in the next five years could be wiped out thanks to AI. The White House report cites a 2013 study from Oxford University suggesting that 47 percent of U.S. jobs are at risk because of AI. The report suggests that lower-skilled and less-educated workers could feel the heat the most. Overall, the White House report advocates a three-pronged approach to preparing for a future remade by AI that includes investing in AI for its benefits, training Americans for the jobs of the future and helping workers make the transition to new positions.

Even in the best case, automation leaves the first generation of workers it displaces in a lurch because they usually don’t have the skills to do new and more complex tasks, Mr. Acemoglu found in a paper published in May.

Robert Stilwell, 35, of Evansville, Ind., is one of them. He did not graduate from high school and worked in factories building parts for tools and cars, wrapping them up and loading them onto trucks. After he was laid off, he got a job as a convenience store cashier, which pays a lot less.

“I used to have a really good job, and I liked the people I worked with — until it got overtaken by a machine, and then I was let go,” he said.

Waymo, the newly-minted Alphabet company that was previously Google’s self-driving car project, has a new addition to its vehicle fleet: 100 Chrysler Pacifica hybrid minivans, which were produced by Fiat Chrysler specifically for the purpose of making them fully autonomous using Waymo’s tech, onboard computer power, sensors and telematics. The 100 new cars will join Waymo’s other self-driving vehicles in active service on public roads for more testing starting early next year.

These vehicles were created through a close partnership between Waymo and FCA that actually saw engineering teams from both companies co-located at a Michigan engineering site, and testing of tech through the development process happened both in Chelsea, Michigan, and Yucca, Arizona on the FCA side, and at Waymo’s own test facilities in California.

While the Chrysler Pacificas used are based on the 2017 production model that consumers can buy, changes were made to the vehicles’ electrical, powertrain and structural systems, as well as to the vehicle chassis itself, in order to make them better suited for using Waymo’s tech. This results in a much tighter integration than if the Alphabet company had just purchased Chrysler vehicles off the line and done their own aftermarket modifications on stock vehicles. Still, from project outset to these being ready to enter service took only six months, according to FCA.

If it works? LOL it’s 1960’s technology.

Shervin Pishevar is a startup investor and one of the central social figures in Silicon Valley. He recently founded Hyperloop One, a project to move people long distances through tubes at supersonic speeds.

His reputation and fortune come largely from a single investment he made in 2011 while at the VC firm Menlo Ventures: a $26 million stake in a small ride-hailing app called Uber. Those shares are now worth more than $5 billion.
