Another good use for AI. Fighting disinformation.

About 60% of adults in the US who get their news through social media have, largely unknowingly, shared false information, according to a poll by the Pew Research Center. The ease at which disinformation is spread and the severity of consequences it brings — from election hacking to character assassination — make it an issue of grave concern for us all.

Nigerian oil and gas regulator protests innocence after FBI says $50,000 in funds stolen from a wind turbine provider ended up in his account.

Oneka.

Out of the total water available on the planet, just about three percent is fresh water that can be used. The rest is salty sea water unsuitable for drinking or industrial usage, and desalination plants have helped put this water to some use.

Japanese scientists have developed a new type of plastic that’s strong at room temperature, but can be easily broken down on demand into its base components. In seawater, it starts to break down into food for marine life, and just to top it off, it can self-heal and remember past shapes.

Plastic is everywhere in our modern world, for better or worse. Its toughness makes it an extremely useful material for everything from household items to vehicle parts, but that same toughness makes it hard to break down for recycling or disposal.

In the new study, scientists at the University of Tokyo developed a new plastic material that can be broken down more easily, either in recycling plants or in nature. It’s based on a class of plastic called an epoxy resin vitrimer, which are strong at room temperature but can be reshaped and molded with a bit of added heat. Normally, vitrimers are brittle, but the team improved the recipe by adding a molecule called polyrotaxane.

Awkward name aside, the Lexus LF-ZC Concept that debuted at the Japan Mobility Show last week is a very big deal. When it goes into production in 2026, it will be the first electric vehicle on an all-new, ground-up Toyota platform; will do some very next-level things with the company’s steer-by-wire technology; and an alleged 620 miles of electric range.

It is not, however, going to do that with some huge battery pack that weighs as much as an apartment building. Instead, it’s going to rely mostly on chemistry to deliver on those big range claims.

As part of the auto show festivities, Toyota invited several international media outlets, including InsideEVs, to Japan last week. There, the world’s largest automaker previewed a number of emerging technology concepts, including a simulated “manual transmission” for electric cars, an advanced in-car AI assistant and its EV battery plans for the next few years.

Electric SUV platform – to be used by next Discovery Sport and Evoque – will underpin new brand Avinya’s EVs.

Tesla is going to integrate Elon Musk’s newly launched Grok AI assistant in its electric vehicles, according to the CEO.

Earlier this year, Musk launched a new AI startup, xAI, and said that it will work closely with Tesla.

The company’s mission is “to understand the true nature of the universe”, but in practice, its first project is to build a chatbot or AI assistant à la ChatGPT.

Things may not have ended well for dinosaurs on Earth, but Cornell University astronomers say the “light fingerprint” of the conditions that enabled them to emerge here provide a crucial missing piece in our search for signs of life on planets orbiting alien stars.

Their analysis of the most recent 540 million years of Earth’s evolution, known as the Phanerozoic Eon, finds that telescopes could better detect potential chemical signatures of life in the atmosphere of an Earth-like exoplanet.

An exoplanet (or extrasolar planet) is a planet that is located outside our Solar System, orbiting around a star other than the Sun. The first suspected scientific detection of an exoplanet occurred in 1988, with the first confirmation of detection coming in 1992.
