Elon Musk hints at a low-cost electric vehicle in the works, made in high volume, with advanced production technology, and the progress in China is a significant factor in Tesla’s success.
Questions to inspire discussion.

On their way to building fully autonomous vehicles, self-driving car makers are facing a tall task: training their AIs to be able to respond reliably to any and all scenarios that a car, truck or bus might encounter as well as, or hopefully better, than a human would. Today, a startup with a platform to help with that challenge is announcing a sizeable round of funding to take those strategies up a gear.
Foretellix, which builds verification and validation solutions to test the full range of driver assistance and autonomous systems that are coming out on the market, has closed its Series C at $85 million. The round includes financial investors alongside strategic backers from the automotive and chip industries, a signal of who is already doing business with Foretellix, as well as the longer business trajectory for the startup.
The round is being led by Israeli VC 83North, with Singapore’s Temasek and carmaker Isuzu investing alongside Woven Capital (Toyota’s venture fund), Nvidia, Artofin and previous backers MoreTech, Nationwide, Volvo Group VC, Jump Capital, Next Gear Ventures and OurCrowd. Foretellix may ring a bell for readers: The first close of this round was in May of this year (at $43 million).
As if space travel didn’t present enough challenges — from bone thinning and an elevated risk of cancer to the sheer tedium of spending months confined to a small capsule — scientists have now warned that prolonged exposure to microgravity and cosmic radiation could lead to erectile dysfunction.
For a NASA-funded study, published in The Faseb Journal, researchers exposed rats to doses of radiation equivalent to that found in deep space, and suspended them in harnesses to simulate weightlessness for four weeks. A year later the blood supply to the rats’ erectile tissue was found to be impaired, apparently mainly as a result of the radiation. The scientists described it as “a new health risk to consider with deep space exploration”, but said that there were signs it could be treatable. When astronauts are in orbit, such as on the International Space Station, they are protected from cosmic radiation by Earth’s magnetic field, which deflects the rays. Further out, they’re fully exposed, and transporting the material needed to shield them is difficult and expensive.
The people who were most afraid of the risks of artificial intelligence decided they should be the ones to build it. Then distrust fueled a spiraling competition.
Imagine brain scanning technology improves greatly in the coming decades, to the point that we can observe how each individual neuron talks to other neurons.
Then, imagine we can record all this information to create a simulation of someone’s brain on a computer.
This is the concept behind mind uploading – the idea that we may one day be able to transition a person from their biological body to a synthetic hardware.
A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly every gene to potentially target and treat a broader range of diseases through genome engineering.
The research involved collaborators at Harvard University, Massachusetts Institute of Technology, University of Massachusetts Medical School, University of Zurich and McMaster University.

A new technique using deep brain stimulation tailored to each patient exceeded researchers’ expectations in treating the cognitive impairments from moderate to severe traumatic brain injury.
In 2001, Gina Arata was in her final semester of college, planning to apply to law school, when she suffered a traumatic brain injury in a car accident. The injury so compromised her ability to focus she struggled in a job sorting mail.
“I couldn’t remember anything,” said Arata, who lives in Modesto with her parents. “My left foot dropped, so I’d trip over things all the time. I was always in car accidents. And I had no filter — I’d get pissed off really easily.”
So our experiences or how we handle those experiences may have an effect on the expression of genes in our body.
A surprising thing happened when researchers began exploring whether early-life stress compounds the effects of a childhood head injury on health and behavior later in life: In an animal study, stress changed the activation level of many more genes in the brain than were changed by a bump to the head.
It’s already known that head injuries are common in young kids, especially from falling, and can be linked to mood disorders and social difficulties that emerge later in life. Adverse childhood experiences are also very common, and can raise risk for disease, mental illness and substance misuse in adulthood.

Languages are a key factor in human societies. They connect people, serve as a vehicle to pass on knowledge and ideas, but they also distinguish between different groups of people. Languages can therefore tell us a lot about the societies that use them. As languages are constantly changing, it is important to know the factors that play a role in this. Scientists can then reconstruct past processes on the basis of languages.
In a study published today (Dec. 5) in the online journal PNAS Nexus, Kiel linguist Dr. Søren Wichmann, together with colleagues from China, demonstrates that average ambient temperatures influence the loudness of certain speech sounds. “Generally speaking, languages in warmer regions are louder than those in colder regions,” says Dr. Wichmann.
The basic idea behind the study is that we are surrounded by air when we speak and listen. Spoken words are transmitted through the air as sound waves. The physical properties of air therefore influence how easy it is to produce and hear speech.
Using lasers rather than scalpels and saws has many benefits in surgery. Yet they are only used in isolated cases. But that could be about to change: laser systems are getting smarter and better all the time, as a research team from the University of Basel demonstrates.
Even back in 1957, when Gordon Gould coined the term “laser” (short for “Light Amplification by Stimulated Emission of Radiation”), he was already imagining the possibilities for its use in medicine. Surgeons would be able to make precise incisions without even touching the patient.
Before that could happen, however, there were—and still are—many hurdles to overcome. Manually controlled light sources have been superseded by mechanical and computer-controlled systems to reduce injuries caused by clumsy handling. Switching from continuous beams to pulsed lasers, which turn themselves rapidly on and off, has reduced the heat they produce. Technical advances allowed lasers to enter the world of ophthalmology in the early 1990s. Since then, the technology has moved on in other areas of medicine, too, but only in relatively few applications has it replaced the scalpel and the bone saw.
